Best Way To Grow Weed Indoors (KISS: Keep It Simple, Stupid)
Last updated December 27, 2020 By Steven 6 Comments
The best place to grow cannabis is indoors.
You have complete control over everything when growing weed indoors, which allows you to really maximize rapid growth and huge yields with incredible potency.
But to get the perfect buds, you need the perfect environment.
The good news is: even if you make mistakes and don’t provide the perfect environment, you will still be harvesting buds. Marijuana is very resilient.
That said, the more things you get right, the better the result.
If you follow the instructions here, you will get all the basics right, while still keeping everything as simple as possible. To me, this is the best balance between great results and not over-complicating things to the point where it becomes stressful and no fun.
So let’s get started, by going through the whole growing process step by step, beginning with the preparation and ending with harvest.
Indoor Marijuana Growing
1. Find A Grow Space
The first thing you need to do is figure out where you will grow your cannabis plants. Are you setting up in the basement, in a closet, etc?
Once you have the space, you want to get it ready for growing marijuana indoors. The easiest way to do this is to get a grow tent. You can find tons of inexpensive tents on Amazon and these cheap tents are good enough for most of us.
Check them out here and just pick one that fits into your grow space and has enough room inside to fit your planned number of plants. If you need especially small grow tents, those can be a bit harder to find. Our article on mini grow tents will help.
2. Get Pots And Soil
Sure, you can grow hydroponically or in a soil-less growing medium without using hydroponics, but in my quest to keep it simple, I recommend growing indoors with soil. It’s easy to find and easy to use.
Any good quality potting soil will work, but avoid anything with artificial extended release fertilizer or that otherwise contains chemicals. Miracle Gro is a good example of a soil to avoid.
The Ocean Forest Potting Soil from Fox Farm is a great option. It contains a lot of nutrients, so you won’t need to any any for the first week or so. If you keep re-potting the cannabis plant, you may never have to add any.
If you start your seedlings in this soil (which I do recommend for simplicity), they will suffer some nutrient burn at first. This is not a huge deal, but you can avoid it if you like, by putting some less nutrient-rich soil on top of the Ocean Forest soil for your seedlings.
When it comes to pots, I recommend the fabric variety. They are by far the best option for growing cannabis.
If you want to use pots you already have, that works fine, too. Just make sure whatever container you use has some holes in the bottom for drainage. If you use a regular bucket, for example, make sure to drill a few holes in the bottom.
When it comes to pot sizes, you’ll want a small pot (1 gallon or less) for seedlings, but you can also just use a plastic cup. After that, you want to transplant the plants into ever larger pots.
Once their roots have expanded throughout their new pot, it’s time to give them a larger one so they have room for growth. An easy way to tell they are ready to move is when the roots start coming out the drainage holes in the bottom of the pot.
At some point, you want to stop giving them larger pots, to keep them from growing ever larger. A good rule of thumb for the largest pot size is this: you need about 2 gallons of container per 12″ in plant height.
Thus, if you want your plants to reach a height of 3 feet, you would need a 6 gallon pot. If you are using fabric pots (as I recommend) go twice as big. In this example, get a 12 gallon pot (or at least 10).
The reason fabric pots should be bigger is that the soil dries out much faster in a smart pot. Making the pot larger, increases the time it takes for the soil in the middle to dry out.
4. Add A Grow Light
There are ton of options for grow lights, but we’re keeping it simple. Just get an LED grow light. They cost less to operate and they’re easier to use. Nowadays, they actually cost the same or less than an equivalent HID system, once you account for all the equipment you need to run HID grow lights.
Those lights will work great for a grow of one weed plant. If you have a bit of a larger grow space, I highly recommend these Spider Farmer lights. They are the best value lights on the market right now and work great for growing cannabis plants.
Spider Farmer only makes lights in four sizes, though. If you need a different wattage, check out the Phlizon COB lights. They are also excellent grow lights and actually cost even less than the Spider Farmer fixtures. Plus, they use COBs, which some still prefer, despite the industry moving more to quantum board lights like those from spider Farmer.
Weed plants love fresh air. They achieve the best growth when they get a slight breeze. It also serves to prevent mold. The best way to give your plants the breeze they need is with a fan on the lowest setting. You can also remove larger leaves or lollipop your plants to improve air flow.
There is no need to spend a lot of money on a specialized “grow tent” fan. You can basically use any fan you may already have. If you don’t have one, you can buy them anywhere.
If you need a recommendation, this one works great.
It is small and comes with both a clip and a stand. That means you can clip one to the tent pole above the canopy and have a second one standing on the ground, blowing fresh air below the canopy. It does not oscillate, but that is not really necessary in a smaller grow tent or grow space.
You’ll also need to draw hot air out of the tent and replace it with cool air. This means you’ll need an exhaust fan, at the very least. You may also need an intake fan. This article helps you figure out your cooling needs.
7. What Else Do You Need For The Growing Process?
Since we’re keeping the process simple, I’ll leave it at the bare necessities. If you’ve only got a cannabis plant or two, you’ll be fine with that.
I do recommend a few additional things, though.
The most important additional items for ideal growth are: a nutrient solution, a pH meter or pH strips, and pH up and down solutions.
If you only have a plant or two, you can get by with just the fan for ventilation. You’ll just have to leave the tent door open at times to replace the air inside.
And you can get by without a charcoal filter to remove the odor as well. Ideally though, you want to ventilate your tent and you want to remove the odor from any air you ventilate out.
8. Start Growing Cannabis Indoors
Now that you have all your equipment gathered, it’s time to start growing cannabis. Well, there is one more thing you need. The most important of all. The actual cannabis plants.
The Best Places To Get Cannabis Seeds
If you know someone who is growing marijuana plants and can hook you up with seeds or clones, lucky you! You can skip this section. If you have clones, head here to learn how to get clones to root faster.
If not, your best bet is to buy seeds online from a seed bank. Most people prefer to buy from a bank located outside the US, though this really doesn’t matter much anymore.
The thinking is that having seeds sent across state lines could get you in trouble, since growing marijuana is a federal crime. But it is highly unlikely that anything will happen. In the highly unlikely event that your seeds are discovered, they will most likely only get confiscated.
But if you buy from outside the country, the worst that will happen is that they are confiscated at customs. That’s it. You don’t even get put on a list. Then you just contact the seed bank and they will send you a replacement shipment (if it’s a good seed bank).
These days, however, this is basically the same thing that happens when you ship inside the US. That is why our favorite online seed banks are both headquartered in Europe, but they have warehouses in the US. This cuts down on shipping times considerably.
Our favorite bank to buy from is I Love Growing Marijuana. They are based in Amsterdam, but they have a distribution center in the California. As mentioned, this cuts down on shipping times. Their seeds are high quality and they even have their own unique strains.
The biggest plus is their germination guarantee. If your seeds do not germinate, they will replace or refund them. The primary drawback is that they currently only ship to the US or Australia. If you do not live in either of those locations, read the next paragraph.
Crop King Seeds is another great option, especially if you are not in the US or Australia. They are headquartered in Vancouver, Canada and they actually have physical stores in Canada as well. They ship anywhere in the world.
For the US, we prefer ILGM, due to their germination guarantee and the free shipping. Crop King has a guarantee, too, but they only guarantee that 80% of the seeds will germinate. They also charge for shipping, with rates in the US being the lowest at $20 and international rates as high as $40.
You can read more about ILGM here and about Crop King Seeds here.
I would always spend a bit more and buy feminized seeds.
Only the female cannabis plants make buds that can be smoked. Buying feminized cannabis seeds saves you the trouble of identifying and removing male plants later on during the flowering stage. It also means you don’t waste time of seeding and vegging male plants, only to have to eliminate them.
I know many beginning indoor cannabis growers want to spend as little as possible, so they start by growing bag seed. I did this myself, so I won’t tell you not to, but you should be aware of the problems you may face.
This article covers all the possible issues and also guides you in maximizing your chance of success if you want to grow weed with bag seed.
Germinating Your Cannabis Seeds
The easiest way to germinate seeds of marijuana plants is to use a starter cube (or seedling plug). Rapid Rooters are great. You can find them here on Amazon. There is even a version that comes with a tray.
You simply put the seed inside, keep it warm and slightly moist and when the sprouts and root appear after a few days, put the whole plug, seed and all, into the soil in your seedling pot. That way you also don’t have to worry about handling the delicate seeds once they have sprouted.
If you don’t want to bother with the Rapid Rooters, you could also just germinate your seeds in the same container that you plan on using for your young seedlings. It could be a plastic cup or a 1-gallon fabric pot or whatever.
To do this, plant them the cannabis seeds about 1/2 to 1 inch deep (1.3 to 2.5 cm). The soil should be moist, but not soaking. Keep it that way during the entire germination process by adding water whenever it begins to dry out. You also want to keep the seeds warm, either with a heating pad or with a light that gives off some heat.
If you are using the Ocean Forest potting soil, you might want to mix it with a lighter potting soil for the seedling pot. If not, the seedling will suffer some nutrient burn, but it is not really that serious. I’d probably mix it, to avoid the nutrient burn, but it will not cause permanent damage to your plants.
Try to keep the temperature during seeding around 73° F (23° C) and the humidity around 70%. Give them 18 hours of light per day, followed by 6 hours of darkness.
You don’t need a powerful LED grow light during this stage, but you can use it. Just hang it higher, to keep from harming the delicate seedlings.
Many growers prefer using a weaker light for seedlings to save on power costs. If you have a lot of seedlings, a T5 light fixture is best. I prefer T5 LED lights. If you prefer fluorescent, you’ll find the best options here.
If you’ve only got a few, a CFL bulb will work just fine. This article tells you what you need.
Once your marijuana plant grows its first set of regular leaves (i.e. not the seedling leaves), it has officially entered the vegetative stage.
Vegging Your Cannabis Plants
The vegetative stage is when your marijuana grow starts to get exciting. The plants grow fast, but do not yet produce any buds or flower. The great thing about growing marijuana indoors is that you get to control everything, meaning you can provide the ideal conditions for maximum yields.
The first and most important thing you have control over is lighting. During vegging, you want to keep your grow lights on for at least 18 hours per day.
Some growers like to give a full 24 hours of light, but I recommend going with a schedule of 18 hours on and 6 hours off.
You also control the air temperature and humidity. For vegging you want the keep the grow area between 70 and 85° F (20 and 30°C), with a relative humidity of 40 to 60% (I’d stay over 50%).
If you don’t have a thermometer or humidity monitor, don’t worry too much. As long a your cannabis plants are not freezing or scorching, they will grow. Keeping the environment in the ideal range just means faster and better growth.
Make sure you water your plants regularly. Whenever the top inch of soil feels dry to the touch, give them more water. Water them until you see around 20% extra runoff water come out of the bottom of the pot. Be careful not to water too often. Always wait until the top one inch of soil is dry.
If you use a nutrient rich soil, your plants will be getting a good amount of nutrients, at least for a while. Eventually, you will need to provide more, by adding them to your plants’ water.
Begin by adding half the amount indicated on the nutrient schedule that came with your nutrients. If plants are growing rapidly and need more nutrients, up the dosage to 3/4 of the indicated amount.
I highly recommend training your plants during vegging.
Left on their own, they will grow tall and end up in a Christmas tree shape. This is not ideal, because it means one large bud at the top and not much else.
You want your plants to grow short and fat, with multiple peaks that are all about the same height. That way, each peak gets the same amount of light and grows the same large bud.
There are a number of ways to achieve this. I prefer bending the young main stem downward and tying it down, forcing it to grow horizontally. Then multiple other stems will grow upward from it. You can find much more on training your plants here.
Whenever your plants grow too large for their pots, but you want them to keep growing, you need to repot them. If you fill the new pot with fresh soil (assuming you are using a nutrient rich soil), remember to stop adding nutrients to the water until the plants have used up the nutrients in the soil (about a week).
How long should cannabis plants stay in vegging?
This is entirely up to you. You can keep them in this stage indefinitely, if you like. This is actually what growers will do with a female plant, if they use her for quality clones.
When you should take your plants from vegging to flowering depends on how large you want them to get. An average strain will double in size during flowering, so you want to take it out of vegging when it is about half the size you would like it to end up having.
This does depend on the strains, though. If the strain is labeled as short, you can expect it to not double in size during flowering. If it is labeled as tall, you can expect it to more than double in size.
Flowering Your Weed Plants
To get your plants to enter the flowering stage, simply adjust the amount of light they get every day. Change the lighting schedule to 12 hours on and 12 hours off and your plants will begin to flower.
Marijuana plants also need a lot more light during bloom, so you want to make sure you give them what they need. Powerful LED grow lights are best, but I also highly recommend CMH lights. HPS works well too, as it always has, but I don’t recommend it anymore, since LED and CMH are better. Assuming quality LED grow lights, of course.
During flowering, plants become more sensitive to humidity, so you want to keep it lower to prevent mold. Keep the temperature between 65 and 80° F (18 and 26° C) and maintain a relative humidity between 40 and 50% during the beginning of the flowering stage and 40 and 45% during the final weeks.
A week or two weeks after you switch to the flowering light schedule, you can finally see the gender of your plants. If you used feminized seeds, they will all be female and you have nothing to worry about.
If you used non-feminized seeds, you can expect about half of your plants to be male. Now that you can identify the males, you need to remove them from your grow room and get rid of them immediately. If they pollinate the females, you end up with buds full of seeds.
You can tell the difference by the pre-flowers they grow at the tops of branch joints (the “V” where the stems meet the trunk):
- Female plants start growing longer and thinner pre-flowers that are often fat on the bottom. Eventually, wispy white hairs emerge from the top.
- Male plants start growing balls/pollen sacs that have no white hairs or pistils. You can get a lot of them, which looks like a bunch of small grapes.
Sometimes the male and female growths look very similar, but if you see white hairs, it is female.
Even after removing the males, you should keep a close eye on the females. It is possible for them to become hermaphrodites, which usually happens if they are stressed. If that happens, you can try removing only the section of the plant that has begun forming male parts, but I recommend removing the entire plant, just to be safe.
If you don’t want to destroy it, you can continue to grow it separately from your other plants. That way you don’t loose the harvest (though it will be full of seeds), but the hermie plant also can’t pollinate the rest of your females.
The other important task during flowering is to make sure your buds are all getting sufficient light. If you see a bud in the shadows, try to get it light so that it can grow and give you extra yield.
The best way to do this is with supplemental lighting. Another reason to add supplemental lighting is if your primary fixture is not heavy in red spectrum light. In that case, some smaller all-red LED lights would really help boost yields.
Some growers will trim off large fan leaves that are blocking light. I would caution against this for your first grow, since those fan leaves are what turn light into energy. If you remove too many fan leaves, your buds don’t get the energy they need to grow big.
Instead, you can try tucking away some of the fan leaves, if they are impeding the light and causing shadows on your buds.
When is comes to actual nutrition, cannabis plants need much less nitrogen during flowering. If you bought a nutrient set made specifically for cannabis, it will contain a ‘bloom’ or ‘flower’ bottle. Switch to that one now, since it contains the right mix for flowering.
For the first month of flowering, your marijuana plants need a lot of nutrients. After that, they need less and less. Reduce the nutrients you give them gradually, starting around the halfway mark of flowering.
During the last two weeks before harvest, it is a good idea to flush your plants. This means you should give them plain water, with no nutrients. This ensures that the nutrients do not impart a flavor on the buds.
Your plants will look like they are slowly dying during this time period. That’s because they are. As the near harvest time, they will look pretty rough, because they stop taking in nutrients and everything they have is funneled into bud growth.
This is normal, so do not panic and give them more nutrients. They do not need them and the nutrients will only harm the flavor of your bud.
In general, the flowering stage lasts a minimum of 2 months (or 8 weeks) and some strains of cannabis need to be flowered for 3 to 4 months. Then it is time to harvest.
Harvesting Your Weed Plants
How do you know when to harvest?
It depends a lot on what you want.
Harvesting a bit early results in buds that give you a buzzed, heady experience. They cause anxiety and headaches in some people.
If you harvest later, you get more of a stony, relaxing bud. Harvesting very late results in weak bud that makes you extra-sleepy (why would anyone want this?).
The good news is: there is a fairly large window of time for when you can harvest your bud. Everything really depends on the strain and your personal preference. Just make sure you don’t harvest too early. That is the biggest mistake people make, so you can usually wait longer than you think you should.
There are two main methods for determining when to harvest. The first is easy, but less accurate. The second requires a magnifier.
Method 1: Check the Pistils
The quick way to determine when to harvest is to look at the little white hairs that grow out of your bud. These are the pistils and eventually they start to curl inward and darken. They can turn any number of colors: red, yellow, purple, pink, brown, etc.
To know when it is harvest time, you first need to wait until your buds stop growing new hairs. This is where many inexperienced growers jump the gun. Make sure they are done growing white hairs, because sometimes they just pause for a bit, then grow more.
Once new white hairs have stopped growing, wait until 40% of them have darkened at least. 40% is the beginning of your harvest window, but you should wait longer.
Harvest when 50 to 75% of the hairs have darkened for maximum THC levels. Wait until 80 to 90 % have darkened for some of the THC to turn into CBN, which is more relaxing and gives you that “fuse-you-to-the-couch”, anti-anxiety effect.
Method 2: Check the Trichomes
This method is more accurate, but you need a magnifier of some kind. A digital microscope works best, since it gives you a more accurate image. That said, a jeweler’s loupe like this one is much cheaper. I’d pay more and go with the microscope.
Use the magnifier to examine the trichomes. These are the crystals, or the frosty-looking stuff you see accumulating on your buds.
You only care about the ones with the ball on top, that look like little mushrooms. These are the ones that give weed its potency. The color of these trichomes determines when to harvest your weed.
- You get more of a heady high when some trichomes are clear and some are cloudy or milky white
- You get the highest THC levels when most of the trichomes have turned milky white or cloudy
- When the trichomes have become darker (generally amber or gold, but sometimes pink or purple) you have reached the end of the harvest window. Harvesting now means more CBN for a more relaxing and anti-anxiety high.
Here is a graphic that shows you what to look for:

Once you have harvested your bud, it is time to dry it and cure it. I will cover that in a separate article, since this one is about growing weed indoors.
If you have any questions about growing, please feel free to leave a comment below. I read them all and will answer any questions I can.
Growing marijuana indoors does not need to be as complicated as many make it seem. Follow these steps and you will get all the basics right and end up with great yields.
How To Grow Cannabis Fast, Both Indoors And Outdoors
The ideal temperament of a cannabis grower is patience. However, sometimes things need to be stepped up a gear. To grow cannabis faster, it’s key to start with faster genetics and an understanding of light cycles.
Gardening is usually a slow, meditative, and therapeutic process. It isn’t a hobby that revolves around instant gratification. Long-term investment and hard work pay off months after the seeds have been sown. Watching the slow and steady growth of plants whilst you stroll around a grow room or garden is deeply satisfying, and makes experiencing the fruits of your labour at harvest time that much richer.
THE CANNABIS ISSUE: YOU NEED BUD FAST!
However, when it comes to cultivating cannabis, some growers simply don’t have the time to spare. There are several reasons for this. Some cultivate the herb on a commercial scale, so the more frequently they can harvest their crop, the faster the turnover is. Other growers, such as those who reside within regions where cannabis is still illegal, desire to get their operations set up and closed down as quickly as possible to avoid getting busted. The faster they can harvest their buds, the less time they have to experience the constant anxiety of draconian laws.
Lastly, some growers who cultivate for personal use, whether for recreational or medicinal reasons, simply want a stash as fast as possible. Luckily for all these groups of growers, cannabis is a versatile species that can handle a broad range of environmental conditions. Environmental factors ultimately dictate how cannabis grows, and humans have mastered agriculture to the point that we can influence growing speed—at least to a degree.
SPEED UP YOUR CANNABIS GROW IN ANY CONDITIONS
When looking to speed up a cannabis grow, there are differences and limitations to growing indoors or outdoors. Ultimately, growing indoors provides much more control over environmental factors that contribute to speed. However, if you prefer to grow outside, or that’s all you have to work with, there are a few things you can tweak to move things along hastily. First, let’s take a look at what can be done indoors.
HOW TO SPEED UP AN INDOOR CANNABIS GROW
Growing indoors means you have a large amount of control over lighting, gas exchange, watering, and temperature. Most of these factors play a key role in rapid growth.
LIGHTING DURING THE VEGETATIVE PHASE
The cannabis grow cycle features two distinct phases: the vegetative phase and the flowering phase. Manipulating the light cycle during both of these phases can result in a faster pace of growth. During the vegetative phase (when plants feature only fan leaves and have not started to bloom), indoor plants are usually vegged under 18 hours of light and 6 hours of darkness per day to provide the best conditions for photosynthesis and respiration to occur.
However, by providing 24 hours of light per day, you will force your plants to remain in an anabolic state (the process of converting smaller molecules into larger molecules). This is because they will be photosynthesising around the clock and constantly using light, CO₂, and water to create glucose as an energy source to fuel growth.
LIGHTING DURING THE FLOWERING PHASE
The light cycle will need to be changed during the flowering phase depending on the genetics being used. Autoflowering strains don’t require a change, a topic we’ll delve into later in this article. However, traditional photoperiod strains require extended periods of darkness to begin flowering. This trait is due to the rhythms of nature; plants evolved to begin flowering when the days begin to get shorter and the harsher conditions of autumn approach. Lack of light is a signal for them to begin reproduction.
To initiate flowering and increase the speed of the flowering phase, a light cycle of 12 hours on and 12 hours off is usually recommended. There is, however, the option to run an 11/13 light cycle, which will make your plant hurry up in fear of the approaching change of seasons. Some growers do both, starting with 12/12 at the beginning of bloom, then moving to 11/13 at the latter half of the phase.
Another trick to speed things up massively is to avoid the vegetative phase altogether and begin flowering your plants immediately after germination has occurred. This can be achieved by applying a light schedule of 12/12 immediately and throughout the entire grow cycle. Although a rapid way to produce flowers, yields will be sacrificed for speed. Plus, this trick is only compatible with photoperiod strains.
MAKE SURE NUTRIENTS ARE DIALLED IN
Nutrients are also key for faster cannabis cultivation. This is primarily because any deficiencies in certain nutrients will result in various symptoms that slow growth and potentially reduce yields. Cannabis plants are hungry for increased levels of nitrogen during the vegetative phase and increased levels of phosphorus and potassium during flowering. To keep things simple, you can always purchase formulations specifically designed for both of these phases to make sure your plants get everything they need at the correct time. Moreover, you should always be diligent about checking pH to ensure your plants can uptake the nutrients they’re being given.
HARNESS THE POWER OF FUNGI
Fungi are simply mind-blowing life forms. Some fungi are pathogenic to cannabis plants and can damage them and slow growth. However, mycorrhizal fungi form a mutualistic allegiance with cannabis plants that can boost their health and growth. When supplementing your soil with these life forms, you will enhance the nutrient uptake of your plants and prevent potential deficiency and disease. These fungi penetrate into the intercellular space of roots where they work to transport nutrients to cells, receiving sugars created by the plants in return.
HYDROPONIC PLANTS ARE KNOWN TO GROW FASTER
Growing plants hydroponically means that water is the primary growing medium, as opposed to soil. This involves suspending plants above a water reservoir in a basket filled with media such as coco coir or clay pellets. The roots eventually grow down into the water below. There are many different forms of hydroponic growing, but the basic premise is that because the roots have direct access to nutrients within the water, they can uptake them with much greater speed and ease, resulting in faster growth.
HOW TO SPEED UP AN OUTDOOR CANNABIS GROW
Growing outdoors offers much less control over certain parameters. This requires a slightly different approach and some creative thinking.
HOW TO CONTROL LIGHT EXPOSURE OUTDOORS
Unlike indoor growers, outdoor growers have to deal with the sun. This constant light source is a great thing for those looking to grow all season long. However, those seeking a fast harvest will need to find ways to reduce light exposure. As mentioned above, altering the light cycle is perhaps the most powerful way to speed up growth. When it comes to achieving a 12/12 light cycle outdoors to initiate flowering from the get-go, growers can cover their plants with a tarp for periods in the morning and evening to avoid excess light exposure.
If you don’t fancy forcing flowering straight away, but still want to speed up the vegetative phase, you can expose your plants to 24 hours of light using the sun during the day and artificial lights at night. Just be aware that this may bring unwanted attention to your growing operation.
POLLINATE YOUR FLOWERS
Pollination is usually something growers strive to avoid. When pollen makes contact with flowers, they become fertilised and seed formation starts. This means energy that would otherwise be directed toward flower growth is instead directed to the formation of seeds. However, by pollinating your flowers by hand approximately 1 week before harvest, you will force them to mature faster. Be sure to harvest them before seeds begin to form.
INDOORS OR OUTDOORS, GENETICS MATTER MOST
Regardless of whether you intend to speed up cannabis growth indoors or outdoors, genetics will play the most fundamental role. Some cannabis varieties have been selectively bred over generations to strengthen the trait of faster growth and flowering. Autoflowering strains in particular are famed for their speed, with most emerging from seed to harvest in a couple of months or so, without any intervention at all. Here are some of the fastest-growing autoflowering and photoperiod genetics you might want to consider for a lightning-fast harvest.
VANILLA ICE AUTOFLOWERING
Vanilla Ice Autoflowering is a speedy lady that will explode from seed to harvest in as little as 55 days, without any of the above methods being implemented. She was created using the original Vanilla Ice, which was then infused with ruderalis. This indica-dominant specimen provides a giggly, happy, and relaxed body high with flavours of vanilla and sugar.
Vanilla Ice Autoflowering has an average THC content of 13%. She’ll yield up to 350g/m² indoors and reach a peak height of 90cm.
Lemon Kush is a fast-flowering photoperiod strain derived from Chemdawg, Lemon Thai, and Pakistani Kush. With a flowering time of approximately 55 days in normal conditions, this indica-dominant cultivar induces a stoning and meditative high shortly after being smoked. The terpene profile within her flowers features notes of spice and citrus.
Lemon Kush provides a rewarding yield both indoors and out. Indoor plants will yield up to 500g/m² and grow to heights of between 100–130cm. Plants cultivated outdoors yield up to 550g/plant and surge to heights of 170–230cm.
