Soma’s Sacred Seeds

Member rating scores

Soma’s Sacred Seeds offers excellent high grade organic cannabis seeds, in Amsterdam and online.

Back in 1967, Soma was working at IBM as a mail clerk in the office products division on Madison Avenue in NYC. Another employee helped him get some Marijuana rolled up in joints. Right after work, he walked down to the East River dressed in his three-piece suit and tie and lit up my first joint. He instantly fell in love with the calm feeling it brought to his whole being. He was 18 years old.

In the 45 years that passed since his first joint he found cannabis to be one of the most positive forces in his life. Soma started growing cannabis in 1971 in southern Vermont. He owned and ran a vegetarian restaurant and bakery. As he became more aware of his diet, a deeper knowledge of ecology and its effect on the environment came with the territory.

This naturally led to growing cannabis in an organic eco-friendly manner. From that point on, he have been finding different ways to make his thumbs greener. This magnificent plant species has helped teach him the art of having and taking care of houseplants, the art of nurturing, and the art of photography to name but a few. Far from being a demotivator, marijuana has become interwoven with many of his interests, and its influence has opened his mind to explore many he might have never other wise pursued. Although marijuana laws are never fair around the planet, he refuses to give up his right to have his sacrament and medicine constantly near him in the form of clothing, food, plants, paper and smoke. In this way he does his part to overgrow the whole darn place.

Soma’s book ‘Organic Marijuana Soma Style’ is available online and at the American Book Center in Amsterdam.

Absolute favorite strain and it’s grown right here in Washington. Smoke this stuff just before work to deal with chronic body pain. Plus it gets me going, focused, and most of all enjoying the shit I don’t want to do! Haha This is great for my social anxiety and all other stress/anxiety. I would highly recommend this strain, not only for the high, but it tastes like Fruity Pebbles. Weed and Fruity Pebbles?! Now that’s the shit.

fast growing weed seeds

Top Fastest Growing Cannabis Seeds By Categories (2020 Update)

Choosing the right seeds is the first most important part of a successful grow. These selections from Autoflowering, Feminized and CBD plants are our most popular fast growing strains. They are easy to grow, produce good yields and deliver the goods all the way.

Cannabis cultivators look for specific traits when selecting a strain. Some search for flavour and potency above all else, whereas others are more concerned with speed. Luckily for both the former and latter camps, the breeders at Royal Queen Seeds have dedicated a lot of time to developing top-quality strains that are quick off the mark and rapid to deliver their goods.

Our team has created both fast-flowering feminized genetics and autoflowering genetics to satisfy all types of growers. The former offers all the benefits of photoperiod strains, but with a reduced flowering time.

Our autoflowering varieties, on the other hand, are the fastest in our archive. Infused with Cannabis ruderalis genetics, these cultivars don’t require external cues to flower. Instead, they surge from seed to harvest in a matter of weeks, making them perfect for stealthy home growers.

Let’s explore the fastest RQS cannabis seeds by category. Though the following timeframes are approximations, they are accurate.

AUTOFLOWERING

Autoflowering seeds can be both sativa and indica. However, they have been crossed with a type of cannabis called ruderalis. This enables them to flower on their own in as little as 2-4 weeks without exposing them to strict 12 hour light regimes.

Some of our most popular strains in this category include:

QUICK ONE

Quick One is one of the fastest auto-growing strains on the planet. The plant is based on the original auto flowering strain – Lowryder. This strain was created from a cross between William’s Wonder x Northern Lights x Ruderalis. These plants are usually ready for harvest in 8 weeks from germination. The plants also reach between 50 and 60 cm and can yield up to 150g per plant.

Quick One
Quick One
Lowryder 1 x Old School Indica
275 – 325 gr/m2
50 – 60 cm
5 – 6 Weeks
THC: 13%
Sativa 10% Indica 60% Ruderalis 30%
100 – 150 gr/plant
60 – 100 cm
9 – 10 weeks after sprouting
Physically Relaxing

EASY BUD

Easy Bud received her name for good reason. As well as being one of the easiest cannabis strains to grow, she also boasts one of the fastest growing cycles. Her speedy and robust nature makes her ideal for those seeking a fast turnover, and those ready to take their first step into the world of growing weed.

As the progeny of White Indica and ruderalis, Easy Bud produces frosty flowers featuring a THC content of 12% alongside citrusy and earthy terpenes. These buds won’t blast you to the moon, but they will offer a soothing and subtle effect perfect for any time of day.

After germinating these seeds, Easy Bud will explode into a mature plant in as little as eight weeks. Prepare to harvest up to 325g/m² from indoor plants, and between 30–80g/plant from outdoor specimens.

Easy Bud
Easy Bud
White Indica x Ruderalis
275 – 325 gr/m2
50 – 60 cm
5 – 7 weeks
THC: 12%
Sativa 15% Indica 55% Ruderalis 30%
30 – 80 gr/plant
60 – 110 cm
9 – 10 weeks after sprouting
Physically Relaxing

ROYAL BLUEMATIC

Not only does Royal Bluematic offer quick results, but she also delivers aesthetically stunning flowers and relaxing body highs. This strain emerged after Royal Queen Seeds crossed the legendary cultivar Blueberry with a high-performing ruderalis variety. Thus, they took the best traits of this classic and made them much easier and faster to cultivate.

After placing her seeds in the soil, growers should be prepared to harvest her bud within a timeframe of 8–9 weeks. Such impressive speed makes her a great candidate for guerrilla growers looking to stay below the radar.

Royal Bluematic blooms colourful buds boasting shades of orange, green, purple, and yellow, as well as a THC content of 14%. Her phytochemical mix provides a stoning high augmented by sweet and earthy flavours.

70 – 120 gr/plant

Powerful , Stoned

FEMINIZED FAST GROWING STRAINS

Feminized cannabis seeds are designed to produce only female plants. Feminized seeds will produce a female plant 99.99% of the time. Don’t waste your time trying to produce flower from a male plant – they will only pollinate you females, resulting in seeds rather than bud.

Fast Flowering strains are hybrids of these and autoflowering strains. They are genetically coded to produce flowers quickly with little care, but still rely on a change in photoperiod to flower.

Some of our most popular selections in this category include:

CANDY KUSH EXPRESS

As well as offering a rapid flowering time, Candy Kush Express is a rich source of terpenes, emanating notes of sugary sweet citrus. Her speed of growth and incredible taste make her a great strain for cannabis chefs who want a crop that yields well on a regular basis. This strain features a close balance of 60% indica genetics and 40% sativa, which exerts an effect that relieves tension from the body while keeping the mind alert and functional.

Candy Kush Express is a speedy photoperiod variety that features a flowering time of only 7–9 weeks. Plants grown indoors under good-quality lights will yield up to 525g/m². Those grown outdoors are capable of yielding between 450–500g/plant.

Cannabis cultivators looking for a quick and easy grow experience read this. These are our top selections in every category of plant.

Top 6 Fastest-Growing Cannabis Seeds

Check out these 6 strains if you’re looking for speed. This mixture of autoflowering and feminized photoperiod strains will race through veg and bloom to deliver a yield with immense flavours and potent effects.

Cannabis strains have been selectively bred over the years to produce specific, desirable traits. Some breeders aim for sheer potency and try to promote max THC levels. Others focus on the therapeutic effects of the herb, attempting to increase CBD and terpene concentrations. However, there is one demand that will always exist among all cannabis growers: speed.

Speed is an important aspect to many different kinds of growing operations. Commercial growers value this trait because of the fast turnover. Discreet growers and guerrilla growers develop a taste for speed as it allows them to begin and end their operation as fast as possible. Below are 6 of the fastest-growing cannabis seeds.

FAST AUTOFLOWERING STRAINS

1. VANILLA ICE AUTOFLOWERING

Vanilla Ice Autoflowering was crafted using the original Vanilla Ice along with a ruderalis strain. Ruderalis genetics are primarily included for their autoflowering traits, with speed of growth being a massive bonus in many strains. Here too, ruderalis delivers the goods, whereas Vanilla Ice transferred her fresh, sugary, and vanilla flavours and indica-dominant genetics. Her THC level of 13% provides a soft and gentle high that is easily manageable, even after several joints and bong hits. She’s perfect for complete novices and those who don’t get along too well with sky-high THC levels.

Vanilla Ice Autoflowering produces impressive harvests of tall and narrow buds within a short time frame. Both indoor and outdoor crops will be ready to harvest a mere 55–65 days after germination. Indoor plants grow to around 60–90cm, making them easy to conceal, and produce a harvest of up to 350g/m². Plants grown outside will remain stealthy among the undergrowth at heights of 50–100cm, yielding 100–175g/plant.

2. CANDY CARAMELO

As her name suggests, Candy Caramelo is known for more than just her brief grow cycle. The trichomes of this strain truly work overtime pumping out terpenes that merge to create mouthwatering flavours of mint, caramel, and sugar. Utilising simple extraction methods such as cannabutter allows users to craft sweet edible delights that are irresistible. Smoking this flower brings on a stoning indica high that soothes the body and induces a chill state for a couple of hours.

The flowers of Candy Caramelo are small, compact, and tapered. But don’t judge them by their size. Each toke is infused with unparalleled flavour and a THC level that hovers around 15%. Expect a yield of 300–350g/m² and a height of 75cm when growing this strain indoors. Alternatively, outdoor plants will pump out 220g/plant and max out at a height of 120cm. Growers don’t wait long to taste these flavours; she’ll be ready to trim as little as 50 days after germination.

3. NORTHERN LIGHTS XL AUTOFLOWERING

Northern Lights XL Autoflowering ticks almost all of the boxes that autoflowering growers are looking for. She offers a good yield, fast flowering time, decent potency, and brilliant aesthetics. To make this possible, the legendary Northern Lights XL was bred with a ruderalis strain, a move that saw highly prolific and legendary genetics shift over into the auto realm. This lady offers a chill and mellow indica high fuelled by a 14% THC level and tastes and aromas of sweetness and citrus.

This speedy specimen pumps out gorgeous flowers that are narrow, tall, and feature shades of green, grey, light purple, and white. When grown indoors, she’ll ascend to a height of around 120cm and yield up to 400g/m². Outdoors, she’ll grow to a taller height of 150cm and deliver up to 230g/plant.

FAST-GROWING FEMINIZED PHOTOPERIOD STRAINS

4. WHITE CHEESE

White Cheese was forged in the grow room using the reliable and productive genetics of Afghan and Skunk. This merging created a fast-flowering delicacy with a rich taste of spice and cheese, and a physical indica high that’s ideal for experiencing in the late evening thanks to its sedating qualities at high doses. A THC level of 17% places her on the more mellow end of the spectrum; it’s enough to induce relaxation without catapulting the smoker into a hazy state of paranoia and overwhelm.

White Cheese will be ready to dry and cure within a brief flowering time of 50 days, reaching a manageable height of up to 90cm and yielding 350–450g/m² indoors. Outdoor plants put out satisfying yields of 150–220g/plant and achieve a maximum height of 120cm.

5. POWER PLANT XL

The highly efficient and extremely productive genetics behind this strain are derived from South Africa. Power Plant XL is known for her massive yield that is conveniently paired with fast-paced growth. Growers will watch the plant flower for around 55 days until they can begin drying, curing, and sampling the fruits of their labour. What’s more, this sativa-dominant lady produces a THC level of approximately 20%. The terpene profile within the flowers augments this experience with flavours of sweet, sour, and pine.

Power Plant XL doesn’t mess around; it’s almost like she wants to be smoked as quickly as possible. These flowers appear on indoor plants in quantities of 600–750g/m², with specimens reaching just over a metre in height. Plants grown outdoors in Mother Nature’s embrace will provide a mammoth yield of up to 600g/plant and peak at a height of around 200cm.

6. LEMON KUSH

Lemon Kush offers an incredibly tangy citrus hit delivered alongside a THC level of 18%. This zesty and refreshing profile complements the indica high well by adding an edge of stimulation and alertness. This interesting combination came about as breeders matched parent Strains Chemdawg, Lemon Thai, and Pakistani Kush. These desirable traits are available to growers after a short flowering time of approximately 55 days.

Lemon Kush isn’t fussy, growing with ease in both indoor and outdoor environments. Indoor plants grow to a height of between 100–130cm and easily yield up to 500g/m². In comparison, outdoor plants top out at 230cm and yield between 450–550g/plant.

Speed is an important factor in cannabis cultivation, and these 6 seeds fit the bill perfectly whether you're a novice or an experienced hand.

How Long do Marijuana Seeds Last?

There is plenty of debate surrounding how long do marijuana seeds last before they go bad. Some people say that they can last for years if they are kept in the correct conditions, while others disagree and state that they can only be used within 6 months to 1 year after packing. So the question is, how long do marijuana seeds last?

In some cases the latter may be true, if they are weak genetics or the seeds have been kept in adverse conditions. How long the seeds will last depends totally on the conditions they are stored in. If the seeds are humid or exposed to light, they will not germinate from being damaged internally. It is also essential to add that the seeds must be protected from being crushed.

Will Cracked Marijuana Seeds Still Germinate?

Unfortunately, the answer to will a cracked seed still germinate is No. It cannot germinate as the valuable internal part of the seed that contains the genetic information of the plant is exposed, then the seed will no longer germinate. Great care must be taken to ensure the seeds are not damaged or crushed, including putting them in vials stuffed with cotton wool to ensure they don’t rattle around and harm each other.

Cannabis seeds can withstand long amounts of time in storage, as long as they are well protected. A cool, dark environment with no humidity or strong aromas is good to store the seeds for a few months, but if you want to extend the shelf-life of the seeds, then they must be refrigerated.

How Long Do Marijuana Seeds Last Before They Go Bad?

As we mentioned before, marijuana seeds can be made to last very long if they are refrigerated. Without any interference, marijuana seeds can last a few months before they go bad, even up to a year if they are kept in a cool, dry and dark place, but if they are refrigerated, marijuana seeds can last up to a decade.

How Long Do Marijuana Seeds Last With Great Care?

How long your seeds will last can vary. If great care is taken for the seeds to be protected from humidity and light, and provided a cool environment the center of the seed will remain dormant, making the marijuana seed last longer. That way, the only thing needed to germinate the seed will be to soak them overnight in water then place them in a damp tissue or Jiffy plug and germinate normally.

So, how long marijuana seeds will last depends on the care you take to conserve your marijuana seeds in the correct way. If you are very careful marijuana seeds last you for ages. You can even stock up on strains to have your own collection and at the same time, remain self-sufficient throughout the year.

How long do cannabis seeds remain viable?

Marijuana seeds should be kept in a cool, dark place such as a basement or in your refrigerator. They should be in an air-tight container and must stay dry. Putting a cotton ball in with the seeds before storage can help suck up any extra moisture (this is why you often see little bits of cotton in seed breeder packs).

Heat and moisture ‘signal’ to cannabis seeds that it’s time to sprout, so as long as you keep the seeds in a dry, dark environment they can remain viable for years. I have heard cases of seeds sprouting after being in storage for 5 or even 10 years. However, you will notice that older seeds take longer to germinate than fresh seeds and a few of them may not sprout at all. As time goes on, fewer and fewer of the seeds will successfully germinate.

What Plants Grow the Fastest From Seeds?

Related Articles

For many gardeners, waiting for seeds to germinate and plants to grow is part of the hobby’s reward. For others, however, it can be maddening, especially if you are gardening with children. Distract impatient growers with fast-growing plants while they wait for the rest of the garden to catch up.

Annual Flowers

Many flowering plants sprout and grow rapidly, and they provide the added benefit of splashes of color for your yard. Sweet alyssum, celosia, cornflower or bachelor button, marigold and cosmos sprout within five to seven days. Zinnias, sunflowers and morning glories bring even more color and quick growth, while fast-growing nasturtiums multitask as garden beauties that you can add to salads or as dinner-plate garnishes.

Perennial Flowers

Dianthus (Dianthus chinensis) will add to your garden year after year, while black-eyed Susan (Rudbeckia hirta) and Sweet William (Dianthus barbatus) are biennial or perennial plants, depending on the varieties you select. These flowery plants will germinate in five to 10 days and grow quickly after sprouting. Other perennial choices include blackberry lily (Belamcanda chinensis), blanket flower (Gaillardia x gradiflora), rose campion (Lychnis coronaria) and gaura (Gaura lindheimeri). All of these perennials are hardy in United States Department of Agriculture plant hardiness zones 3 through 8, while many thrive through zone 10.

Herbs

Not only do many herbs germinate and grow quickly, they add fragrance to the garden and flavor to your menu. Consider basil, which sprouts in about four days, or chives, cilantro and dill, which make their appearance seven to 14 days after planting. Mint grows quickly, as well, but you’ll probably want to plant it in containers to keep it from invading other areas. Garden cress adds a sharp aroma and a peppery taste to dishes.

Vegetables

Several vegetables grow very quickly, including most types of lettuce and radishes. Cucumbers germinate within seven to 10 days, as well, and mustard greens, spinach, scallions and turnips hold their own in the race. Blue Lake and Pencil Wax bean varieties are especially suitable for quick gardening, and cucumbers, squash, cantaloupe and watermelon, with their four- to six-day germination period make excellent garden additions.

Miscellaneous Plants

Noted in Thomas Jefferson’s garden journal as early as 1812, hyacinth bean vines can grow 6 to 20 inches in a single season, twining through the garden, their maroon seedpods and purple flowers bringing tropical drama to the landscape. Grasses, especially wheat grass and rye, also grow quickly. Add a little fun by growing grass in a hollowed potato decorated with craft wiggle eyes, so that it seems to grow green hair.

Fast Growing Seeds for Kids

Here are some great ideas for fast growing seeds – perfect for kids!

First: Get Your Supplies!

Next: Get to Work!

Whether you are introducing your kids to gardening, or making crafts or science projects that involve growing seeds – it can often be beneficial to use seeds that sprout quickly! I did some research and tried out various options. One of our favorite ways to plant seeds is in plastic cups. Cheap, transportable (great for classrooms!) but also you can actually see the roots forming!

Vegetables and Herbs:

Radishes, lettuce, basil and salad cress (more common in the UK than in the US!)

We planted radish and basil seeds and grew them inside. The radishes were SUPER fast, sprouting in just three days. This photo was taken after six days:

The basil took a little longer, this was after two weeks:

Annual flowers:

Sweet alyssum, celosia, cornflower or bachelor button, marigold, cosmos, zinnias, sunflowers, morning glories and nasturtiums.

We planted some sunflower seeds outside but they didn’t sprout for two weeks – although we did have a couple of unexpected cold days during that time that may have delayed them.

Perennial flowers:

Dianthus, black-eyed Susan, Sweet William, blackberry lily, blanket flower, rose campion and gaura.

We planted some Sweet William seeds in plastic cups and although not as fast as the radish, they were fairly speedy! This photo was after a week:

And don’t forget grass! We didn’t have any grass seed to try out but they are perfect for crafts like this Grass Head activity from Red Ted Art.

To increase the chance of any of these seeds growing faster – you can also try planting them in Seed Starter Mix! Or try this wildflower mix of annuals and perennials – everything you need in one bag!

Common Mistakes Made While Growing Seeds Indoors

Guidance on Watering, Lighting, and Other Growing Factors

  • Pin

  • Email

The Spruce / K. Dave

It is quite economical to start seeds indoors, especially when the seedlings grow into robust plants. However, growing seeds indoors can be challenging. To significantly increase your chances of success, avoid these common seed-starting mistakes.

Watch Now: Mistakes to Avoid When Growing Seeds Indoors

Not Supplying Enough Light

Seedlings need a lot of light to grow into sturdy, healthy plants. No matter what anyone tells you, chances are that you do not have enough natural light in your home to grow robust seedlings. Even a south-facing window usually will not do. You can, however, use artificial light to achieve the right amount of light required by seedlings. To do so, obtain grow lights explicitly designed for plants. Or, for a more economical solution, purchase large fluorescent shop lights outfitted with one warm bulb and one cool bulb.

Suspend the lights from chains so that you can raise the lights higher as the seedlings grow. Keep the lights as close to the seedlings as possible without touching them (2 to 3 inches). When seedlings first appear, keep the lights turned on for 12 to 16 hours per day. To reduce your hands-on time, use a timer to turn the lights on and off automatically.

Applying Too Much or Too Little Water

The amount of water you supply can make or break seedling growth. Watering is one of the most challenging aspects of seed starting. Because seedlings are so delicate, there is very little room for error when it comes to watering. You must keep the sterile seed-starting medium damp but not wet.

To increase your chances of getting it right, here are a few things you can do:

  • Create a mini-greenhouse to keep soil moist: cover the container with plastic until the seeds germinate.
  • Water from the bottom to enable the seedlings to soak up water through the container drainage holes. There is less chance of over-watering when you use this approach. Add water slowly for 10 to 30 minutes, and use your finger to touch the top of the soil to ensure that moisture has reached the top of the container.
  • Check soil moisture at least once a day.
  • Buy a self-watering, seed-starting system.

Starting Seeds Too Soon

Many plants do not tolerate cold temperatures, and exposing them to chilly air or cold soil will stress them out. Chas Gill, who runs the Kennebec Flower Farm, agrees that one of the biggest mistakes people make when starting seeds is starting the seeds too early. Stressed-out plants are more susceptible to pests and disease. Most plants are ready to go outside four to six weeks after you start the seeds.

Planting Seeds Too Deeply

Seeds are finicky when it comes to how deep they are planted. Some seeds need complete darkness to germinate and others require light to germinate.   Proper planting depth is usually provided on the seed packet. If there is no information on the packet, the rule of thumb is to plant seeds two to three times as deep as they are wide. Determining depth can be a challenge, but if you are not sure, err on the shallow side.

For seeds that need light to germinate, make sure the seeds are in contact with the seed starting medium but are not covered. To do this, gently press the soil medium to create a firm surface. Then, place the seed on top of the medium and gently press down, making sure the seed is still exposed.

Moving Seedlings Outdoors Too Soon

There is no benefit to a tough-love approach with seedlings when they are young. They will either instantly die or become weak and then fail to thrive. Even the most stalwart plants, when young, need a considerable amount of coddling and attention.

When your seedlings are large enough to plant outdoors, you need to prepare them for the transition by hardening off.   Hardening off gradually prepares them for outdoor conditions like wind, rain, and sun. The hardening-off process is simple, though it can be time-consuming; it involves exposing your plants to the elements gradually. The first day of hardening off, place your seedlings outdoors for one hour, and then bring them back indoors. Gradually increase the amount of outdoor time every day for 6 to 10 days. You will need to make some judgment calls based on the outdoor temperature and the fragility of your seedlings. If it is a particularly cool day or very rainy, you will want to decrease the time of that hardening-off session.

Sowing Too Many Seeds

When sowing seeds, begin modestly if you are a beginner. If you sow more seeds than you can reasonably maintain, it will become challenging to nurture the seedlings into adulthood. Depending on the type of plant you want to grow, you might be able to direct-sow seeds in outdoor containers or in the ground when outdoor temperatures warm up.

Keeping Seeds Too Cool

For seeds to germinate, most must be kept warm: about 65 to 75 degrees Fahrenheit. A favorite place to keep seeds warm in order to germinate is on top of the refrigerator. Or, you can purchase seed-warming mats to place under the seed trays. Once a seedling emerges, they can tolerate fluctuating temperatures (within reason). Whatever type of light you use, natural or artificial, make sure it produces enough heat to keep the plants in the 65- to 75-degree range.

Failing to Label Seeds

To be able to identify seedlings as they grow and to know when they will be ready for transplanting, you should label the seed containers as you are sowing. For every type of seed sown, use popsicle sticks or plastic plant markers and permanent ink pens to record the plant name and date sown. Insert the plant labels into the soil near the edge of the container or tray.

Giving Up Too Soon

Starting seeds can be a difficult process. However, one of the most satisfying benefits of this labor of love is eating a tomato or marveling at the flowers that you nurtured from day one. Growing plants from seed takes dedication, attention, and time. Recognize that you might make mistakes along the way, but you should not give up. The results outweigh the challenges along the way.

Growing seeds indoors isn't hard, yet keeping them alive can be challenging. You can save a lot of money by starting plants from seeds.

Growing Seedlings Under Indoor Grow Lights

Anyone who’s tried growing plants from seed knows that proper lighting is critical to producing an abundance of stocky, green seedlings. For those of us lucky enough to have a south-facing window with 12+ hours of full sun, lighting isn’t an issue. But for the rest of us, an indoor lighting system of some kind is a necessity.

This primer on indoor lighting for seed starting will help you choose the options that work best for you.

Light Color

Light color is also referred to as color temperature, with cool light describing the blue end of the spectrum and warm light being the red end. Sunlight contains the complete spectrum of light, including all colors of the rainbow.

Although plants use the full spectrum for photosynthesis, red and blue light seem to be most critical. Red light stimulates vegetative growth and flowering (but if a plant gets too much, it will become tall and spindly). Blue light regulates plant growth, which makes it ideal for growing foliage plants and short, stocky seedlings (but too much will result in stunted plants).

You can tell which color a grow light produces by looking at its Kelvin rating. Lamps with a rating of 5000 Kelvins will appear bluish, while those with a 2500 Kelvin rating will be reddish.

Light Intensity

The intensity of light that a plant receives is determined by the wattage of the bulb and the distance between the plant and the light source. So, for example, a brighter bulb that’s farther away from the plant could provide the same light intensity as a dimmer bulb that’s closer to the plant.

Different plants have different light intensity needs, but most seedlings grown for the garden will need higher intensity light to flourish. In general, the leaves should be about 2 – 4 inches away from the light source (assuming use of a fluorescent bulb – see below).

Duration of Light Exposure

There’s still debate about how many hours of supplemental light is ideal when starting seeds and growing plants indoors.

Most vegetables and garden plants require at least 16 to 18 hours of light each day; without enough light, they get pale and leggy. The conventional advice was to turn lights on for 16 hours each day. However, some growers maintain that 24 hours of consistent light every day provides a better outcome when growing seedling (i.e., there’s no need to give seedlings a nightly rest but this advice doesn’t necessarily apply to full-grown plants).

It’s certainly easier to leave your grow lights on all the time and that’s what I do. If you choose to go with 16 hours on, 8 hours off, put the lamp(s) on a timer so you won’t forget to turn the lights on or off.

Types of Bulbs

You can choose between incandescent, fluorescent, LED, and high-intensity discharge (HID) bulbs, each of which has its own pros and cons. Choose the grow light that works best for the type of plants you want to grow and where you plan to grow your seeds.

Incandescent Bulbs

These include halogen bulbs and are the type of light bulbs still used in most homes (although they’re getting harder to find now that stores are carrying only more efficient bulbs, such as CFLs and LEDs).

Incandescent bulbs are a good source of red light, but a poor source of blue, meaning that plants will likely become spindly when grown under incandescent light.

Incandescent bulbs, and especially halogen bulbs, also produce a lot of heat in relation to the amount of light they give off; plants growing too close to the bulb can be easily burned.

Generally speaking, these are not the best type of lamps for growing seedlings.

Fluorescent Bulbs

These types of bulbs produce two to three times more light than incandescent bulbs for the same amount of energy and are the most inexpensive lights for indoor gardening. However, they usually require bulky external ballasts (like, for example, overhead shop lights) so aren’t as easy to work with as incandescent and LED bulbs.

Cool white bulbs are a good source of blue and yellow-green light, but are a poor source of red light. Plants grown under cool white bulbs will be stocky or even slightly stunted. Warm white bulbs emit plenty of orange and red light, but less light in the blue and green spectrum. These bulbs, when used alone, result in tall, spindly plants. If you are growing seedlings under two-bulb fluorescent fixtures, you can usually achieve a good color balance by combining one cool white and one warm white bulb.

A set of stacked shelves with fluorescent T5 lamps (or LED lamps) makes it easier to grow a large number of seedlings.

Full-spectrum fluorescent bulbs produce a balance of cool and warm light that replicates the natural solar spectrum, although these are less energy efficient than other fluorescent bulbs and tend to produce more heat. But, given the wider range of light frequencies emitted by these bulbs, they are a good choice for growing seedlings.

T5 lamps are fluorescent lamps that are 5/8″ of an inch in diameter, making them much less bulky than typical fluorescent bulbs. These are the lamps you’re most likely to find in grow light kits.

When using fluorescent lamps, be sure that all plants get ample light. For a typical seedling tray, that means using 2 bulbs, ideally with a reflector hood over them to focus all the light on the seedlings below.

LED Grow Lamps

Unlike other bulbs which produce light across a broad spectrum, light-emitting diodes (LEDs) give off light within a narrow band. LEDs designed for growing plants emit light in the two bands that plants need – red and blue. The result is a purple glow that not everyone likes.

LEDs are mercury-free and won’t shatter like glass. These bulbs are long-lived (up to 5x longer than fluorescent lamps) and very energy efficient, but they cost considerably more than fluorescent bulbs.

Research is still ongoing to determine which combination of light frequencies are best for plant growth and how LED grow lights compare to fluorescent bulbs in producing healthy seedlings. I haven’t seen a definitive answer on this one yet but more and more companies are producing LED grow lights and seed-starting kits, and even commercial growers are slowly moving in that direction.

High-Intensity Discharge Lamps

These lamps are used by commercial growers and serious horticulturists. These energy-efficient bulbs generally emit twice the amount of light (lumens) as a fluorescent bulb. However, the bulbs and special fixtures are considerably more expensive than those needed for incandescent or fluorescent lights. They also tend to be high-wattage bulbs, so you need to be sure your electrical system can handle the load. Some of these lights burn so brightly that they must be located in a special room and you’ll need to wear eye protection when working around them.

Metal halide lights emit an intense, bluish-white light that is excellent for growing plants. The foliage stays green and vigorous, and plants are usually stocky and strong. Metal-halide lights are currently the number one choice for serious indoor gardeners. Mercury vapor lamps emit a bluish, relatively well-balanced, high-intensity light. High-pressure sodium bulbs are usually used to promote flowering and fruiting but, when used exclusively, they produce leggy, weak-stemmed plants.

What’s the best option?

For the average home gardener starting seedlings indoors, a fluorescent or LED lamp will usually be the best choice to ensure that your plants get the quality, intensity, and duration of light they need to stay in peak condition.

how to germinate seeds in rockwool

How to Grow Lettuce from Seed in Rockwool

In this tutorial we are going to learn how to grow lettuce (type: May Queen) from seed in the rockwool as growing medium. The process is easy and straight forward.

Equipment need

Before we start we have to make sure that we are having all necessary parts for growing lettuce. The parts that we need are:
– A pack of May Queen Lettuce seeds
– A sheet of rockwool blocks
– A water pH Meter
– A pH Minus solution
– A thermometer that can measure the temperature of the water and the temperature of the air
– A enough large transparent food container with cover

All the things needed in this tutorial you can buy at local garden or hydroponics store. Or if there is none of them around, you can find them on this Amazon list here: http://amzn.to/1TkwktC

Prepare rockwool for planting lettuce

  1. First we take a bowl and that is large enough to have all of our rockwool soaked in water.
  2. Fill 3/4 of bowl with tap water
  3. Take a pH meter and remove the black cap from it.
  4. Place pH meter tip (the point that cap was placed before we removed it) in water and turn the pH meter ON.
  5. Wait few minutes for value to stabilize
  6. If the pH level is higher than 4.0 then add few drops of the pH Down (or pH Minus) liquid to bowl and stir it well and go to 3. point of this step and repeat points 3,4,5 and 6 until you get pH level of the water in bowl to be 4.0
  7. Now you can put cap back to pH meter and turn pH meter off and place it somewhere else
  8. Take the thermometer and check the temperature of the water
  9. If temperature is not in range of 15 to 20 ВєC (59 – 68 ВєF) then heat up or cool down water so it’s temperature is in our desired temperature range
  10. Now we can place our rockwool in the bowl with water
  11. Put it aside for 30 min and then place it on the steep surface so the rockwool can release all unnecessary water.
  12. Leave the rockwool on that surface for 15 min before proceeding to next step.

Make holes in the rockwool

In case that your rockwool is combined with many pieces in one big piece now is the time to split it in those smaller blocks.
1. Take a small stick, wooden or plastic it doesn’t matter, just make sure that it is not more than 2.5mm wide. For example you can use stick for placing small meat pieces on the grill or toothpick.
2. From bottom of the stick measure 6 mm and with the marker or pen write a tin line exactly on 6mm point from the bottom of the stick
3. Take each block of the rockwool and push the stick in it so that you reach that 6mm mark that you’ve previously made. Please take special caution to make sure you don’t push the stick more than 6mm in the rockwool.

Place the seeds in rockwool holes

  1. Takeout the seeds from packaging
  2. Place a single seed in each hole that we’ve previously made in the rockwool.

To make it easier, you can use the stick that we used before and carefuly with the stick push the seed inside the hole. Also make sure that you don’t push the seeds more than 6mm in the rockwool.

You can also put a ice cream stick on the edge of the rockwool and write the date so later when you plant more lettuce you can easily see when are the seeds planted

Place the seeds container near the window

  1. In the transparent food container place all the rockwool blocks so the holes are facing up and close the lid
  2. With thermometer check the temperature in the room, it should be in range of 15 to 20 ВєC (59 – 68 ВєF). In case your room temperature is warmer or colder than accordingly adjust the temperature so it is in between 15 and 20 ВєC (59 – 68 ВєF)
  3. Place the food container near the sunny window

In next 2-4 days we should see small sprouts coming out. During this time please maintain the room temperature in between 15 and 20 ВєC (59 – 68 ВєF), also check the rockwool and see if it’s drying out, and if necessary spray water on it so it get moisture but make sure to not over water the rockwool so when you pull the block of the rockwool up, water should not leak from it.

How to use Rockwool Cubes for Growing, Seed Starting, and Cutting Propagation

Rockwool is a mainstay growing media for commercial hydroponics growers, primarily those who implement drip irrigation systems. Originally used as insulation and also known as mineral wool or stone wool, rockwool was developed in Denmark back in the 1970’s for gardening. It retains moisture well, it retains oxygen well, it never impedes root growth, it is chemically inert, and it comes in a variety of sizes and shapes. These benefits contribute to its popularity amongst growers, accommodating almost any plant they are growing.

Here is my favorite Rockwool brand.

What are Rockwool Cubes?

Similar in texture to steel wool, rockwool is a dense mat consisting of long strands of natural fibers. Basalt rock and chalk are combined and then melted at a very high temperature (approximately 3000°F) to form lava. Then people throw the lava into a spinning chamber to create the fibers in a process much like making cotton candy.

Due to the firing process, rockwool cubes are chemically and biologically inert. This creates an ideal growing medium for hydroponic growing systems.

After the fibers are spun, they are mixed with a binding agent and pressed into large mats. The mats are then cut into various sizes of cubes and slabs to be sold to customers as a growing medium for plants.

Rockwool cubes are popular with hydroponics growers, as well as conventional growers because of their beneficial structure. When the fibers are spun it creates a structure that is perfectly suited to retain water while holding more oxygen than typical soil mediums. The increased water holding capacity and oxygenation within the root zone is exceptionally beneficial when starting seeds and rooting propagation cuttings.

Another benefit to rockwool cubes is they are considered to be a natural product even though they are man made. This is because they originate from basaltic rock and chalk which are natural ingredients. Being considered a natural product makes them acceptable in organic growing systems, increasing their popularity.

Their inert nature also means growers can quickly adjust the conditions within the root zone to meet the needs of plants. A non-existent cation exchange capacity (CEC) prevents nutrients from being changed by the growing medium or tied up and made unavailable for plant uptake. The cubes can also be quickly rinsed with fresh water, leaching fertilizer salts out.

Rockwool cubes come in a couple of different sizes. The smallest ones work well for starting seeds and propagating stem and leaf cuttings; the larger cubes are used by growers to grow more compact plants.

Do’s and Don’ts of using Rockwool Cubes

One of the drawbacks to using rockwool cubes is the special care and consideration that needs to be taken when working with them. While they are a beneficial resource for hydroponics growing system, they do have some important drawbacks that need to be addressed.

  • DO take the time to properly prepare rockwool cubes before starting seeds or trying to root cuttings. Their natural pH is too high for optimum plant growth and will create problems and instability within the hydroponics system if left at that alkalinity.
  • DO wear protective gear to keep yourself safe when handling rockwool material. The fibers are irritating to skin, lungs, and eyes so it’s imperative to protect yourself. At the minimum, wear a dust mask to prevent inhaling fibers into your lungs. It’s also recommended to wear eye protection and long sleeves if there is a chance of prolonged contact with your skin.
  • DO sterilize the feeding solution before running it back through the rockwool cubes. Even though it is a manmade, inert material, it can still be prone to algae and bacterial growth that can contaminate the hydroponics system if the feed solution is recirculated without being treated properly.
  • DO dispose of the materials properly after you are done using the cubes. Unlike other growing mediums, rockwool is not composed of natural materials so it will not break down over time. If it reaches the landfill it will be there indefinitely. Instead of throwing them away, break up the pieces and work them into your garden or potting soil to help increase their water retention.
  • DO heat treat the rockwool cubes if you are going to reuse them for a successive growing season, or even numerous seasons. This can be done by steaming them, or pouring boiling hot water through them to kill off any bacteria or fungus that may be residing with the cube’s fibers. Some websites recommend using chemical treatments to sterilize rockwool cubes to use again but this can be dangerous unless you are absolutely sure you have rinsed all of the sanitizing chemicals out of the fibers.
  • DON’T squeeze the cubes when they are wet. If you need to remove some of the water from them after preparing them in a pH controlled solution it’s best to shake them gently. Rockwool cubes are known for their internal structure that gives them such great water holding capacity and oxygen movement; squeezing them compacts the structure and hinders the benefits they are so well known for.
  • DON’T forget rockwool is completely inert and can not provide any nutritional value to the plants growing in the cubes. Everything the plant needs has to come from the nutrient solution supplied to them.

How to Prepare Rockwool

Before using your rockwool in a hydroponics system it’s important to prepare it for use. Unlike other pH-neutral hydroponic growing media like Hydroton, and Coco Coir, Rockwool has a naturally high pH, typically around 8.0, because of the way it’s manufactured. During the process there is an abundance of lime that is deposited on the fibers; lime naturally neutralizes acidity, raising the pH.

A pH of 8.0 isn’t optimum for growing plants so it needs to be adjusted to a level that is better suited for growth. A higher pH will make many plant essential nutrients unavailable for plant uptake, causing deficiency symptoms. Most plants prefer to grow in slightly acidic conditions, and will benefit if the pH of rockwool cubes is brought down to a more acidic level.

There are different ways to prepare rockwool for use, none of which are difficult, but they can be time consuming. Due to this you will need to account for a couple of days to prep rockwool before being able to use it.

The first step in preparing rockwool cubes is to soak them in acidic water to lower the pH. The acidic water will dissolve the lime that is formed on the fibers during the manufacturing process and the pH will drop to a better level.

It is best to use distilled water because of its purity but tap water can work in a pinch if it is the only thing available. Adjust the pH slowly until it reaches the desired 5.5; it is critical the pH doesn’t drop below 5.0 since it will start todamage the rockwool fibers when it is too acidic.

After Then submerge the rockwool cubes in the water and allow them to soak for up to 24 hours. When they have finished soaking, remove them from the water and carefully add them to the hydroponics system and allow the system to run without any plants until the pH of the system stays between 5.5 and 6.0 — this means the cubes are stable and can be used.

This video will show you how to prepare rockwool properly.

What are the Uses of Rockwool Cubes

Rockwool cubes hold a tremendous amount of water for their size, which provides a buffer against power outages that make shut down pumps or timers. On average they also hold at least 18% oxygen between the fibers providing a tremendous amount of oxygen to the root zone, as well as making it incredibly difficult to overwater the plants.

Growers primarily use rockwool cubes as growing media for two main purposes in their hydroponics systems: germinating seeds and propagating new cuttings. Typically the 1.5” cubes are used for starting seeds or propagating cuttings. Some of the larger cubes (up to 4”) are used as a growing medium for compact plants as well, but on a much smaller scale.

Germinating Seeds

Starting seeds can sometimes be a stressful adventure. It’s a constant balance between keeping them wet enough to promote germination without having them so wet they dampen off and die. Rockwool cubes are popular for germinating seeds in because of their excellent moisture retention — they are great at helping to keep seeds or seedlings from drying out but don’t let them sit in a waterlogged environment.

Moisture is the critical factor in seed germination. Water enters the seed through the seed coat or tiny opening called a micropyle. The presence of water will activate the enzymatic reactions within the seed that begin germination.

Cloning New Plants

Propagating new plants is the process of taking an existing plant part (usually a leaf or stem cutting) and growing it into a whole new plant. This method results in an identical clone of the original and is cheaper than purchasing seeds and starting from scratch.

Maintaining a high humidity around the cutting is critical for successful propagation. Plants need to keep from drying out; without enough moisture the plant will go into self-defense mode and will stop trying to develop new roots.

Growing new plants through propagation techniques needs to happen in a sterile environment, free of bacteria or fungus. Rockwool cubes are completely inert because of the heating process they undergo during manufacturing. This ensures they are sterile and free of any harmful microorganisms that could hinder propagation.

Step by Step Instructions Using Rockwool for Seed Plantings and Propagating Cutting

  1. Prepare the rockwool cubes for use, making sure to soak them in pH adjusted water to bring their pH down between 5.5 and 6.5.
  2. To Plant Seeds:
    1. Insert 2 seeds in the hole on the top of the rockwool cube. Use a toothpick or other similar object to press the seeds down to the bottom of the hole.
    2. Pinch the hole closed.
    3. Place the cubes in a nursery tray and cover with a humidity dome to lock in moisture.
    4. Maintain at 70 – 80°.
    5. Keep rockwool cubes moist by watering sparingly every couple of days or misting with a spray bottle when they start to dry out.
    6. Remove from humidity dome and place under lights as soon as seeds sprout.
    7. Cut the tops off the seed in each cube (if you planted 2 per cube) that isn’t the strongest or tallest. Do not pull them out as it may dislodge the healthier plantlet at the same time.
    8. Transplant when plantlets reach 2-3” in height.
  3. To Propagate Cuttings
    1. Water the stock plant well the night before beginning the propagation process.
    2. Remove a 3-4” leaf stem cutting from the main stem of the plant, cutting it off as close to the main stem as possible without damaging the node.
    3. Dip cut end in rooting hormone.
    4. Plant the cutting in the rockwool cube making sure it doesn’t poke out the bottom of the cube.
    5. Fill a nursery tray part way full with perlite or vermiculite.
    6. Set rockwool cubes on top of growing media.
    7. Cover nursery tray with a humidity dome to lock in moisture.
    8. Maintain close to 80°.
    9. Crack humidity dome when roots begin to emerge, gradually increasing the day after.
    10. Remove the humidity dome a couple of days after roots first appear.
    11. Transplant when roots begin to poke out the bottom of the cubes.

Conclusion

Rockwool cubes are an indispensable product in the hydroponics growing industry. Naturally occuring basaltic rock and chalk are melted down at really, really high temperatures in a molten lava. This lava is then put into a spinning chamber to create long fibers that are later formed into blocks or cubes for easy handling. Rockwool cubes are popular because they retain moisture and oxygen well and they never impede the development of roots. With a variety of sizes and shapes available, they are adaptable to almost any grower’s setup.

Rockwool is a mainstay growing media for commercial hydroponics growers. I’m going to find out its use, how to prepare, and use it for growing, and propagation

10 Fast-Growing Cannabis Flowers for Impatient Gardeners

Growing cannabis can be an arduous process. Beyond the space, materials, and nutrients needed, time and light are the most essential ingredients in the cannabis cultivation equation. But what if you’re impatient or short on time? Is there a way to speed up the growing process?

Historically, black market growers would seek out or hybridize strains to harness attributes that catered to their surreptitious needs. These plants would usually be short and stalky with larger-than-average yields, and in some instances they would be autoflowering (such as a ruderalis hybrid). They were designed to be fast-flowering for both a quick turnover and so they could be easily relocated from time to time.

The fast-flowering cannabis strains listed below are now emerging for professional and hobby growers to utilize. They’re perfect for novice growers as well as set-it-and-forget-it growers who want to squeeze out a harvest with little time to spare. The list includes a mixture of both photoperiod and autoflowering varieties so you can find the perfect plants for your setup.

Wondering if you can legally grow in your state? Check our state-by-state guide to home cultivation laws to find out.

Photoperiod Strains That Grow Quickly (7-9 Weeks)

Lowryder

Lowryder is a hybrid strain that was inbred for nine generations by Joint Doctor Seeds to give it a dwarfed size. Growing no more than 16 inches tall, it’s the cannabis equivalent of a bonsai for the discrete grower’s windowsill or balcony. Lowryder’s small size comes from a species of cannabis ruderalis crossed with Northern Lights #2 and then William’s Wonder. Consumers, be patient with this strain: its medicinal and cerebrally stimulating effects have a slow but powerful onset. A mild earthy aroma radiates from the small, conic buds which autoflower in a short 40 to 45 days. Lowryder is a stalwart plant that can survive in harsh, colder climates, making it a popular strain in northern regions like Finland and Canada.

Critical Kush

Critical Kush from Barney’s Farm is a mostly indica strain that blends together two famed cannabis staples, Critical Mass and OG Kush. Aromatic notes of earthiness and spice usher in a calming sensation that relaxes the mind and body. Critical Kush pairs a staggeringly high THC content with a moderate dose of CBD, making this strain a perfect nighttime medication for pain, stress, insomnia, and muscle spasms. Growers cultivating this strain indoors will wait 50 to 60 days for Critical Kush to complete its flowering cycle.

Early Girl

Early Girl is the wallflower of cannabis strains since its introduction in the 1980s. Lovingly preserved by the breeders at Sensi Seeds, this strain is lazy and relaxed, nothing over the top. A 75/25 indica-dominant hybrid, Early Girl is a good one for those new to cannabis who would like relief from stress. Also a great strain for novice growers, it’s compact, resilient, and has a particularly short flowering time of 7 to 8 weeks. Early Girl grows especially well outdoors, but won’t put up a fuss if she’s stuck inside.

OG Kush

OG Kush makes up the genetic backbone of West Coast cannabis varieties, but in spite of its ubiquity, its genetic origins remain a mystery. Popular myth maintains that Chemdawg and Hindu Kush parented OG Kush, passing on the distinct “kush” bud structure we see in many strains today. However, we can’t be sure because OG Kush first came from bag seed in the early 90s. The earliest propagators (now known as Imperial Genetics) are said to have brought the seeds out of Florida to Colorado and southern California, where it now flourishes. There are many different phenotypes of OG Kush, some of which include Tahoe OG, SFV OG, and Alpha OG.

OG Kush is cherished for its ability to crush stress under the weight of its heavy euphoria. It carries an earthy pine and sour lemon scent with woody undertones, an aroma that has become the signature of OG Kush varieties and descendants. With OG Kush, patients most commonly cite improvements in migraines, ADD/ADHD, and stress disorders.

Superglue

Superglue is a hybrid strain bred by Seedism Seeds. A cross between Afghani and Northern Lights, Superglue inherits indica growth patterns along with a sweet caramel and pine aroma. Superglue brings calming relaxation to the mind and body, but leaves you functional and energetic enough for social activities or a productive afternoon.

Autoflowering Strains That Grow Quickly (7-12 Weeks)

Red Dwarf

Red Dwarf is a rarer strain of cannabis that is an autoflowering plant. This trait comes from its cannabis ruderalis genetics, which is a third variety of the plant that’s usually not bred due to its lower THC content. The wonders of selective breeding from Buddha Seeds have resulted in seeds that grow to adulthood in an incredibly short six weeks. This strain’s squat, small plants are easy to grow in smaller spaces, making it a popular choice for growers who want something simple and fast. Indica-dominant, Red Dwarf will eventually make you sleepy, but not without some relaxed euphoria first.

Hobbit

Hobbit by Kannabia Seeds is a resilient autoflowering variety with sweetness and strong elemental resistance. This strain has a sweet aroma that has been described as “strawberry candy” and an equally sweet smoke with latent earthy notes. Hobbit deftly combines stimulating Haze elements with a pervasive body buzz that is lightly weighted while remaining pleasant and functional. Many growers covet this autoflowering wonder for its quick 65-day flowering time and above-average yield.

White Ryder

White Ryder is Riot Seeds’ attempt to create a ruderalis version of White Widow by crossing Buddha Seeds’ White Dwarf against Lowryder. By blending two stout, autoflowering plants, Riot Seeds created a potent indica-dominant hybrid that finishes in under 80 days and can easily be hidden from view. Enjoy this flower for anti-anxiety and sleep-inducing effects.

Purple Cheese

Purple Cheese is an indica-dominant autoflowering hybrid that combines Purple #1, Blue Cheese, and Lowryder. Bred by Auto Seeds, Purple Cheese was designed to have a sweeter, less cheesy flavor than its Blue Cheese parent. It does, however, inherit a tight bud structure and a high CBD profile. With a palatable fruit aroma, Purple Cheese delivers powerful full-body effects best suited for night owls or patients treating pain. Colder climates will bring out this hybrid’s purple hues, and for best results, growers should keep this autoflowering variety between 50-80 cm in height.

Royal Haze

Royal Haze (or Royale Haze) by Dinafem Seeds is a mostly sativa strain bred from Skunk, Haze, and Northern Lights genetics. Taking after her Haze parent, this sativa inherits a spicy citrus flavor and buzzing, energetic effects that keep you alert and productive throughout the day. Outdoor growers will appreciate her flexibility and resilience even when the temperature drops, although her 10-11 week flowering cycle demands a bit of patience.

An autoflowering rendition of Royal Haze was bred by Royal Queen Seeds, who mixed Amnesia Haze, Skunk, and a ruderalis strain. Its effects are similarly energizing and cerebral.

These fast-flowering cannabis strains are perfect for novice growers as well as set-it-and-forget-it growers who want to squeeze out a harvest with little time to spare.

Top Fastest Growing Cannabis Seeds By Categories (2020 Update)

Choosing the right seeds is the first most important part of a successful grow. These selections from Autoflowering, Feminized and CBD plants are our most popular fast growing strains. They are easy to grow, produce good yields and deliver the goods all the way.

Cannabis cultivators look for specific traits when selecting a strain. Some search for flavour and potency above all else, whereas others are more concerned with speed. Luckily for both the former and latter camps, the breeders at Royal Queen Seeds have dedicated a lot of time to developing top-quality strains that are quick off the mark and rapid to deliver their goods.

Our team has created both fast-flowering feminized genetics and autoflowering genetics to satisfy all types of growers. The former offers all the benefits of photoperiod strains, but with a reduced flowering time.

Our autoflowering varieties, on the other hand, are the fastest in our archive. Infused with Cannabis ruderalis genetics, these cultivars don’t require external cues to flower. Instead, they surge from seed to harvest in a matter of weeks, making them perfect for stealthy home growers.

Let’s explore the fastest RQS cannabis seeds by category. Though the following timeframes are approximations, they are accurate.

AUTOFLOWERING

Autoflowering seeds can be both sativa and indica. However, they have been crossed with a type of cannabis called ruderalis. This enables them to flower on their own in as little as 2-4 weeks without exposing them to strict 12 hour light regimes.

Some of our most popular strains in this category include:

QUICK ONE

Quick One is one of the fastest auto-growing strains on the planet. The plant is based on the original auto flowering strain – Lowryder. This strain was created from a cross between William’s Wonder x Northern Lights x Ruderalis. These plants are usually ready for harvest in 8 weeks from germination. The plants also reach between 50 and 60 cm and can yield up to 150g per plant.

Quick One

EASY BUD

Easy Bud received her name for good reason. As well as being one of the easiest cannabis strains to grow, she also boasts one of the fastest growing cycles. Her speedy and robust nature makes her ideal for those seeking a fast turnover, and those ready to take their first step into the world of growing weed.

As the progeny of White Indica and ruderalis, Easy Bud produces frosty flowers featuring a THC content of 12% alongside citrusy and earthy terpenes. These buds won’t blast you to the moon, but they will offer a soothing and subtle effect perfect for any time of day.

After germinating these seeds, Easy Bud will explode into a mature plant in as little as eight weeks. Prepare to harvest up to 325g/m² from indoor plants, and between 30–80g/plant from outdoor specimens.

Easy Bud

Sativa 15% Indica 55% Ruderalis 30%
30 – 80 gr/plant
60 – 110 cm
9 – 10 weeks after sprouting
Physically Relaxing

ROYAL BLUEMATIC

Not only does Royal Bluematic offer quick results, but she also delivers aesthetically stunning flowers and relaxing body highs. This strain emerged after Royal Queen Seeds crossed the legendary cultivar Blueberry with a high-performing ruderalis variety. Thus, they took the best traits of this classic and made them much easier and faster to cultivate.

After placing her seeds in the soil, growers should be prepared to harvest her bud within a timeframe of 8–9 weeks. Such impressive speed makes her a great candidate for guerrilla growers looking to stay below the radar.

Royal Bluematic blooms colourful buds boasting shades of orange, green, purple, and yellow, as well as a THC content of 14%. Her phytochemical mix provides a stoning high augmented by sweet and earthy flavours.

70 – 120 gr/plant
70 – 100 cm
11 – 12 weeks after sprouting
Powerful , Stoned

FEMINIZED FAST GROWING STRAINS

Feminized cannabis seeds are designed to produce only female plants. Feminized seeds will produce a female plant 99.99% of the time. Don’t waste your time trying to produce flower from a male plant – they will only pollinate you females, resulting in seeds rather than bud.

Fast Flowering strains are hybrids of these and autoflowering strains. They are genetically coded to produce flowers quickly with little care, but still rely on a change in photoperiod to flower.

Some of our most popular selections in this category include:

CANDY KUSH EXPRESS

As well as offering a rapid flowering time, Candy Kush Express is a rich source of terpenes, emanating notes of sugary sweet citrus. Her speed of growth and incredible taste make her a great strain for cannabis chefs who want a crop that yields well on a regular basis. This strain features a close balance of 60% indica genetics and 40% sativa, which exerts an effect that relieves tension from the body while keeping the mind alert and functional.

Candy Kush Express is a speedy photoperiod variety that features a flowering time of only 7–9 weeks. Plants grown indoors under good-quality lights will yield up to 525g/m². Those grown outdoors are capable of yielding between 450–500g/plant.

How to Grow Cannabis in a Greenhouse: A Guide

Growing cannabis in a greenhouse is an effective cultivation method that combines the perks of outdoor growing with those of indoor cultivation. Learn all about it below!

Learn to grow cannabis in a greenhouse.

Contents:

Growing cannabis in a greenhouse is ideal because it combines the benefits of outdoor growing with those of indoor cultivation. In this guide, we’ll show you how to do it, offering tips and advice as we go along. If you don’t have a greenhouse yet, and want to build one, we can show you how to do that, too.

WHY GROW CANNABIS IN A GREENHOUSE?

Maybe you’re wondering why you’d want to grow weed in a greenhouse, as opposed to growing indoors in a tent or having an ordinary outdoor grow in your garden. Let’s look at the advantages of greenhouse cultivation over other growing methods.

YOU CAN EXTEND YOUR GROWING CYCLE

You can extend the cultivation period into the fall and winter seasons simply by adding more light during cloudy days, and progressively keeping them on longer to compensate for shorter daylight hours. Likewise, if you want to start a new grow before the end of winter, you can add a low-powered light to supplement natural daylight.

PROVIDES THE IDEAL MICROCLIMATE FOR GROWING CANNABIS

A greenhouse environment can sustain higher average temperatures than chilly open fields or gardens. Plus, during cold or hot seasons, you can heat or cool a greenhouse if needed. Even without a heater or cooling system, a greenhouse will provide a more consistent range of maximum and minimum temperatures, without the extremely dry and hot conditions typical for indoor grow rooms. A more consistent microclimate means healthier plants and bigger harvests.

ALLOWS FOR YEAR-ROUND CULTIVATION

The climate within greenhouses can easily be controlled, for instance by opening windows or installing fans. And, since the walls of a greenhouse keep humidity and heat inside, it allows for year-round cultivation. This control over climate and exposure to light isn’t possible in regular outdoor cultivation.

MORE CONSISTENT HARVESTS

Greenhouse harvests tend to be more consistent over time, both in quantity and quality. This is also why the majority of commercial medicinal cannabis produced today is grown in greenhouses.

MORE ENERGY-EFFICIENT THAN INDOOR GROWING

Since cultivators can take advantage of natural sunlight, growing in a greenhouse is way more energy efficient. You will also have much lower electricity costs compared to growing in a room or tent.

PROVIDES PROTECTION FROM THE ELEMENTS

Unlike outdoor cultivation, a greenhouse protects your plants from the elements. There is no threat of rainfall or storms harming your precious ladies. In addition, a greenhouse prevents scavenger animals from having their way with your crops.

KEEPS PLANTS SAFE FROM DETECTION

A greenhouse allows for discreet growing with a greatly decreased risk of detection. Your plants will be safe and secure, so you can go to sleep without worrying about thieves and vandals.

IT’S NOT EXPENSIVE

Growers don’t need to spend a lot of money to set up a greenhouse. A simple walk-in greenhouse can be purchased for little money, and will do a decent job of housing your plants. Building a DIY greenhouse is another inexpensive option. For a simple grow using natural light and hand-watering, there’s no need for expensive grow equipment.

HOW TO GROW WEED IN A GREENHOUSE?

Growing cannabis in general involves many variables that need to be kept in check. Growing in a greenhouse is no exception. However, differences in methodology from indoor and outdoor cultivation need to be taken into account. Here is a list of steps you can take to run a successful greenhouse grow.

PICK A SUITABLE STRAIN

Cannabis strains differ in how they grow, and in regards to their requirements. The best type of cannabis for your greenhouse setup ultimately depends on a number of factors, including your local climate, available space, and whether you’re planning to use an artificial grow light. Let’s dig in a little deeper:

AUTOFLOWERING SEEDS

Autoflowering cannabis is optimal if you’re growing using natural sunlight. As autoflowers don’t require a set light schedule to veg and flower, variations in sun exposure won’t harm your plants or diminish yields as much as photo-feminized plants. This also means you can plant and harvest autos in your greenhouse at any time of year—as long as you support ideal environmental conditions.

Lastly, the smaller size of most autoflowering varieties comes in handy if space is constrained, which is usually the case with small greenhouse setups. To make up for lower yields from smaller plants, you can simply grow more of them in your available space (e.g. the sea of green method).

FEMINIZED SEEDS

Growing photoperiod feminized cannabis is also possible in a greenhouse, but comes with some constraints, especially if you’re using exclusively natural light. As these strains flower based on the hours of light they receive, you rely on the seasons to support vegetation and stimulate flowering.

However, you could also set up an artificial grow light on a timer to control your plant’s development. But then you may also need to look into making your greenhouse light-proof. Otherwise, the natural daylight could interfere with your artificial light schedule, causing its own issues.

Another issue when growing photo-feminized plants in a greenhouse is that you may need to train and prune your ladies to prevent them from growing out of contol. Especially if you’re using only sunlight, plants can get tall and spindly, and may require some topping, scrogging, and the like to remain at a reasonable height.

PLAN YOUR GROW WINDOW

With natural light as the main source of energy in your greenhouse, you need to plan your grow window accordingly. Ideally, you want to be ready as soon as daylight hours (and temperatures) start increasing in spring.

Even though your greenhouse will maintain higher temperatures than those outdoors, you should wait until there is no risk of frost before bringing your plants into the structure. Depending on your location and local climate, this may be early or quite late in spring.

GERMINATE INDOORS

Building on the above, you can always germinate your seeds indoors and start nurturing your plants with low-powered CFLs to give them a head start. You won’t need much space for this, and CFLs tend to run cheap. This way, even if the rest of your grow is conducted using sunlight, you can still take full advantage of the outdoor growing season.

MOVE SEEDLINGS TO THE GREENHOUSE GRADUALLY

As soon as your plants get a little bigger and stronger, after about a week or two, you can gradually get them used to their new growing environment. Go easy on them, and don’t move them abruptly from the cosy indoors to the greenhouse. Set them in the structure for just a couple of hours each day and increase over the first few weeks.

This way, stress is reduced and plants can continue to develop without a hitch. Your plants are sensitive, especially at this stage, so don’t use your greenhouse as an excuse to be negligent.

SUPPLEMENT LIGHTING ACCORDING TO WEATHER

One of the great things about greenhouses is that they allow growers to supplement natural lighting with an extra grow light. Stretches of poor/cloudy weather can be overcome without fear of a diminished harvest, and your electricity bill will be vastly lower than if you grow indoors.

Then again, if one is growing in a suitable climate with plenty of sun, a supplemental light may not be necessary. Still, having one at the ready is never a bad thing for a cannabis grower.

USE BLINDS OR COVERS TO FORCE FLOWERING

A greenhouse makes it possible to force-flower cannabis using light deprivation techniques. Elaborate timed shutters could be installed to obscure plants for this purpose, but simple blackout covers or blinds can also do the trick—at a fraction of the price and with much less effort.

In addition to allowing you to flower your weed at any time, blackout covers also serve to prevent cannabis light pollution (e.g. nearby street lighting), which could otherwise interfere with flowering for photo-feminized plants.

Cannabis cultivation can take place indoors, outdoors, or in a combination of these two venues: the greenhouse . A greenhouse, traditionally fashioned from glass, can be as small as a tool shed or as large as an industrial building. If you have enough space to accommodate even a small marijuana greenhouse, this option may propel your cultivation to the next level.

In this guide, you’ll learn why growing cannabis in a greenhouse can be effective as well as the first steps you’ll need to take to do it.

Benefits of growing marijuana in a greenhouse

The key word when it comes to cannabis growing in a greenhouse is control . A greenhouse provides the ideal meeting point of an indoor and outdoor climate while eliminating the unpredictability of the latter. Periods of rain and wind can wreak havoc on your weed garden, but a greenhouse protects plants from the elements. Likewise, pests, bacteria, and diseases are less likely to invade your plants in the shelter of a greenhouse.

A marijuana greenhouse also puts you in control of two primary factors in a successful grow:

Lighting: A greenhouse gives cannabis plants the benefit of natural light without exposure to harmful environmental stressors. The sunshine also translates to savings in your pocket since you won’t have to worry about the electricity bill for all those LED lights.

Climate: In addition to protection from rain and wind, marijuana greenhouses can contain helpful tools like dehumidifiers, fans, air conditioners, and heating systems, none of which are possible for outdoor growers. With the help of these tools, greenhouses can weather all different seasons, making them an excellent choice for year-round cultivation.

What type of greenhouse is best for growing cannabis?

Whether you want to grow recreational weed or medical marijuana, the best greenhouse may be one that you build yourself. If you have the time and skills (or helpers) to construct your own greenhouse, this route will be the most cost-effective.

Building your own greenhouse requires an ideal location facing the sun. A slightly shaded area is fine, but make sure nothing is keeping the sun’s light from reaching your greenhouse. The more hours of direct sunlight, the bigger the yield.

Think about the storage space you’ll need for equipment such as supplemental lighting and nutritional blends. You’ll also need an easily accessible place to store water and soil, so that the greenhouse is a one-stop location for all your cannabis cultivation needs.

Consider which greenhouse material will create the ideal environment for your cannabis. While glass is the traditional material, you can also use fiberglass or plastic. The latter two will be equally effective but not as fragile or expensive. Whichever material you choose, make sure you install proper ventilation to let your plants breathe.

Before you start building a greenhouse, check local laws to see if building permits or other formalities are needed.

Buying a cannabis greenhouse

If DIY is not your style, then you should be able to purchase a top-quality greenhouse at a relatively low cost. Here are two popular design choices:

Polytunnel: These dome-shaped greenhouses have an aluminum base and a covering of polythene. Polytunnels are on the lower end of the price range, starting at around $200. These greenhouses are durable but do need some maintenance, especially replacement of the cover every five years or so.

Cold frames: Cold frames are another affordable choice. While it’s possible to construct a cold frame yourself, you can purchase a solid one for between $300 and $600, depending on the size. Cold frames are constructed out of wood or plastic and covered in clear plastic. This kind of greenhouse can be used as is, with only heat from the sun, especially if you live in a warm, dry climate like California. In a colder climate, consider installing a heating system, also known as a hotbed.

Neither of these choices should break a modest budget, but be prepared to maintain and/or replace parts as necessary.

Growing marijuana in a greenhouse

Once you have selected the type of greenhouse that works best for you, it’s time to put your gardening skills to the test. Here are the most important aspects of growing top-quality weed in a greenhouse.

Soil: First and foremost, invest in top-quality soil as this will impact the entire growing process. Pick a nutrient-packed soil that contains organic substances like compost and worm castings. Pay attention to the pH levels of the soil as well — aim for a range of 5.8 to 6.3. Other qualities to look for in soil include good drainage ability, high oxygen levels, and effective water retention.

Equipment: From heating systems to oscillating fans, the supply list for a cannabis greenhouse can be long. But once you make an initial investment in equipment, most equipment will last season to season.

Knowledge: The most high-tech equipment won’t matter unless you have a thorough foundation in how to grow cannabis . This means understanding when seeds should be sown (generally April), when flowering occurs (8 to 12 weeks typically), and which cannabis strains do best in greenhouses (autoflowering strains such as Purple Punch Auto, Jack Herer , and 8-Ball Kush enjoy a great reputation among cannabis growers).

Should I grow weed in a greenhouse?

To answer this question, consider how much control you would like to have over your crops. If reliable conditions make growing cannabis a more enjoyable experience for you, then a greenhouse may be the way to go. Also, assess how much elbow grease you want to put into the growing process and if you want to build a structure from the ground up. Finally, evaluate your budget and grow goals before you make the decision to grow marijuana in a greenhouse. Whether you choose to grow weed outdoors, indoors, or in a greenhouse, raising plants from seed to harvest can be a rewarding experience.
