A step-by-step guide describing the best way to germinate your cannabis seeds. This germination method is ideal for the indoor and outdoor grower. Whether you are growing pot for personal use or for income, it is crucial to give your plants the best start in life possible. Just as with animals and children, healthy beginnings will encourage rapid, strong growth. You have two basic options for growing your own cannabis: start with seeds or use clones. If you choose the seed route, you will want to know the best way to germinate marijuana seeds. Experimenting with marijuana germination is your best bet for determining what’s right for you, since even seasoned growers often argue about the best methods for germinating marijuana seeds. And maybe you have been using trial and error but ended up thinking, “Why won’t my marijuana seeds germinate?”” Truth is, you’ve likely been making some mistakes without knowing it. You can increase your results, although some seeds inevitably will be duds. No one can attain 100% germination, but there is room for improvement regardless. DripWorks is happy to provide this primer on how to germinate marijuana seeds fast. These methods can get you and your seeds off to a good start. Select the Right Seeds Germination simply means getting a seed to sprout a taproot, which will serve as its main root into the soil as it grows. For the best results, start with the best seeds you can afford to buy online or get from friends. Choose between indica and sativa according to your preferences for cannabis effects or the market’s demand. You will also have dozens of strains to choose from. If possible, get feminized seeds. Because female pot plants produce the bodacious bud that cannabis connoisseurs crave, starting with feminized seeds will produce more buds when the plants mature. Feminized seeds won’t provide 100% female plants, but they will greatly increase your odds from the 50-50 chances of a standard seed selection. Germination How long does it take to germinate marijuana seeds? Typically, it will take anywhere from a couple of days to up to a week to see your seeds start to turn into plants. There are five basic germination methods that are popular. With any of these methods, remember that seeds will need adequate warmth, moisture, and air to germinate properly. Generally, cannabis seeds like a temperature of 70° F to 90° F for sprouting. Paper Towels The paper towel method is a favorite for many home growers. Simply take two pieces of paper towel. Moisten them with water. Then place your pot seeds in between the two layers of moist paper towels. Put a plate or other object under the bottom towel to prevent moisture damage and another over the top towel to keep the seeds in a dark space. When you see the white taproot emerge from your seeds, they will be ready to transplant. Make sure to plant them taproot down. Water Soaking Lots of folks like this simple, direct method. Simply soak your seeds overnight in a glass of lukewarm water. The next day, plant them directly in the ground, containers or wherever you plan to grow them. Direct Planting This is an even more natural method than water soaking. Just plant your seeds 1/2 inch to one inch deep in soil or another medium that has been moistened. A key benefit of this technique is that your seedlings won’t be subject to transplant shock. Because they have grown up in their surroundings, they will have acclimated to them. Jiffy Pots Some folks like to germinate their seeds in Jiffy Pots. You can buy these at nurseries and other places as little round disks. When you are ready to plant, just add water. They will expand into little individual soil pots you can use as a growing medium. Plant a seed or two in each pot, making sure to keep the pots moist. Once the plants sprout, you can transplant them in their Jiffy Pot to a container or to a raised bed or garden plot. Germination Station Also known as seed starters, germination stations are like mini greenhouses. They include a tray filled with soil and a heat pad underneath to keep the soil warm. A clear plastic cover on the top keeps the warmth in. You can make one of these at home or purchase one inexpensively at your local nursery or online. Simply plant your pot seeds in the growing medium and let them grow. When they are big enough, transplant them to a place where they will grow to maturity and harvest.

How to Germinate Cannabis Seeds

Germination is the beginning of your cannabis seeds’ life and is easy to master. At this crucial stage, seeds grow and sprout into young seedlings. The best genetics deserve the best start, and all you need is two plates, some paper towel, and water. Apply the best germination method today and enjoy a great harvest.

1. Germination set-up

Prepare the first plate by lining the inside surface with two to three layers of damp paper towel. Drain excess water from your plate.

Place cannabis seeds on the top surface of the damp paper towel. Approximately three per plate; ensure they are not touching but are evenly spaced apart.

Add only a few layers of damp paper towel on top of the seeds, and let any excess water drain from the plate. Too much water lowers the chance of successful germination.

To complete the set-up, place the remaining plate upside-down and on top of the first plate, resembling pearls inside a clam.

2. Germination

Cannabis seeds need a dark, warm, and humid atmosphere to germinate.

Around 21°C (70°F) is perfect. Check the paper towels every second day and if required, spray with water to keep conditions moist for your seeds.

After a few days, tiny roots will begin to emerge. Congratulations! Your seeds have survived their first stage of life. Don’t worry if some of your seeds have not yet changed, they may just need a little more time as germination can take up to 14 days.

3. Plant of the seeling

Once the roots are a few millimetres long, they are ready to be delicately transferred to a small container filled with your growing medium of choice (rockwool, coco-fibre, or soil).

Make a hole in the growing medium that is 2 – 5 mm deep. Use tweezers or your fingers to transfer germinated seeds gently into the hole (root pointing down) and lightly cover with a fine layer of your medium. Do not pat it down too hard. The stem and the first tiny set of leaves, called cotyledons or ‘seed leaves’, should begin to emerge 24 to 72 hours after the seeds are planted.

4. Supplying a light source

Seedlings must be exposed to sunlight once they sprout. Ensure this is a gradual process as too much heat causes stress and will stunt growth.

Find a sunny place where you can begin to increase sun exposure, such as a windowsill. Ensure sun exposure is increased by an hour or so a day.

For an indoor plant you can use a fluorescent light (keep normal distance from bulb) or HID lighting (50-80 cm from the bulb).

Take care in the first week or two, as seedlings are still quite delicate and sensitive to the elements. They won’t need a lot of attention until the vegetative stage so avoid overhandling.

Germination is the beginning stage of the growing cycle, and this easy-to-follow guide gives your premium genetic cannabis seeds the best start to life.

Hi, Once seeds have sprouted, how long can or should you leave them to grow under 24 hr lights before moving to your outdoor garden?

Good afternoon Ken,

I hope you’re having a great day.
For the vegetation process, a light schedule of 18 hours of light, and 6 hours of darkness is preferred. Many growers get plants acclimatized to outside by placing them in a window, or under direct sunlight for a few hours a day.

Thanks again, and have a great day!

Hello everyone, all these suggestions are wonderful but I think a lot of you make it sound a little overwhelmingly. I’ve been very successfully cultivating for decades and I’ve always just placed my seeds, be it 1 or 100, in between 2 folded sheets of tissue which I’ve made wet with tap water. I then place them on a tray or plate in a warm dark area , such as an airing cupboard and leave for how ever long they take usually, 12 to 24 hours. The ONLY thing I do which takes effort is PH balance the water I germinate them in and I’ve only lost 5 seeds in nearly 40 years .

Good afternoon Paul,

I hope you’re having a good day,
Thanks for sharing your experiences with germination. pH balancing is a great tip You also might be interested in our new Jamaican Pearl Feminized Grow Report

Thanks again, and I hope you continue to enjoy the blog,

I lightly score my seeds by shaking them inside a rolled up piece of sandpaper – sandpaper side on the inside before leaving them in a cup of water for a few hours to hydrate. I then place them between wet (good quality) paper towel per instructions above. I find using an old plastic takeaway container with a heatmat below keeps the humidity high and with good end results.

Good morning Jonny,

Thanks for sharing your methods for germination with us, the heat mat and low-humidity are great tips!

Thanks again, and I hope you continue to enjoy the blog,

I have found out that the best and fastest way is to take a glass of clean/filtered water and place the seed right on top of the water (floating – NOT immersed in it!). If the seed is viable it will sprout in no more than 48 hours. Right after that you plant it in your pot/soil etc and you’re done.

Good morning Mary Jane,

Thanks for your support, and for sharing your experiences with germination!

What happend if they sink I had em sink they came out fine

Once you put the seeds in water they normally won’t sink straight away, leave it for around 5 hours and then tap your seeds and they all should start sinking if they don’t then they won’t work. But still leave them over night and tap again and take out the ones that didn’t sink and throw them away or plant if you want to try your luck.. take all the other seeds out and follow instructions above you’ll see the open within a day..

Are you saying they sprout in the glass of water and don’t “drown”?

No, don’t leave the seeds in water for longer than 24 hours or they will drown.. after around 12 hours all your seeds should have sunk if they haven’t then just give them a tap and they will sink.. then take them out and follow the paper towel and plates instructions

Take aluminum foil flatten it out and put on top of your dirt it detects planes and grow it just like a tomato plant

Good morning Tammy,

Thanks for getting in touch with Sensi Seeds, and sharing your germination method with us!

Thanks again, and I hope you continue to enjoy the blog.
With best wishes,

Detects planes? Like magnetic? I’ve always has best success 24-48 hours soaked In water, spring water if possible. Usually do this in a shot glass, once they pop I’ll take a paper towel fold so it’s 2 layers then fold once more so you know where center is. Dump the seed in the middle of the edge and the true center (reason we folded a 2nd time)as well as the water just enough to saturate the paper towel. Do not soak! Carefully with the seed in the middle using sterile tweezers turn so the tap is growing down. This will prevent circling and tangling if doing multiple seeds. Now you can fold the other half so your seed will be “sandwiched” between 2 layers. At this time carefully take a corner and the waters attraction should keep your paper towel from unfolding but just in case be gentle. Holding it from 1 corner you can dangle it over a cub or the original shot glass so any extra water runs off. Now take a standard zip or press n seal sandwhich bag and slide your napkin in Carefully . REMEMBER which way was down! Work the air out making jt flat snd seal. Find a temperate dark area around 70°. A cabinet works we’ll as your going to prop it up with taproot facing downwards. Now just close it up and wait in 24-72 hours checking once a day. In rare cases you could have a 1/2″ tap root in the first 24 hrs some may take 4-5 days. Once the tap is about 1/2″-3/4″ long its ready for transplant into its first small pot. With this paper towel method I typically have 100% success.

Can you leave your seed to develop longer roots in the germination phase and can this make them better to grow or is a big no no?
Last year, I had 2 seeds that had really long roots with lots of secondary roots coming out when they were planted, one of which died after a couple of weeks and the other grew into a huge plant.
The other two seeds only had a short germinated growth and both died almost immediately after planting so not sure what I can learn from this…lol

Appreciate any thoughts and advice

Unfortunately, legal restrictions mean we can’t answer grow-related questions or give grow advice on this blog. However, other readers of this blog will often answer questions like yours.

Please check out the following articles on our blog which I think you may find of use, and I hope you continue to enjoy the blog!

With best wishes,

How often do you water and how wet should the plant be? Please.
Also if they are outdoor plants do you need to keep them covered with clingfilm for a wee while or do you just hope for the best. Thanks

This article, about how to water cannabis plants, should answer your questions. I can’t help you with the clingfilm one though, as it depends on the climate. Good luck, and happy gardening!

With best wishes,

Just drop the seeds in water, they will sprout , don’t have to use a towel and check it all the time , drop it in the water , let it float then it will sink and the root will grow out ,let the root get 1/4 inch and plant it where it’s going to grow , 8 hours sunlight starting as soon as it is out of the soil. Always grows great , don’t have to transplant from cup to gallon to bigger and bigger , if it’s growing outside put it where it stays , always does just fine.

Good afternoon Graham,

Thank you so much for sharing your experiences with germination.

Thanks again for your comment, and I hope you continue to enjoy the blog.

Have a great day!

I recommend this article to all breeders and cultivators who plans to germinate seeds and to some who don’t know how to germinate seeds, this article has the best and perfect ways on how to do it.

I have large bay windows at my condo which get about 11-12 hours of light per day. They are tinted but warm. I grow other indoor plants there perfectly. Is an ok place for my pot plants?

This sounds like a great place for all kinds of plants! I recommend you have a look at autoflowering varieties, as otherwise light pollution may negatively affect the flowering cycle. Good luck, and happy gardening!

With best wishes,

How to germinate marijuana seeds

Germination begins the life of your plant, so it is essential to understand precisely how to do it. There are many methods for germinating marijuana seeds – some more successful than others.

This guide will discuss the many ways to germinate your seeds as well as some strategies for ensuring you get the best results possible. But if even the right methods fail I stand by my seeds and replace non-germinated seeds for free.

About germinating cannabis seeds

Too long to read? Watch the video

It starts with the seed

Like all plants, marijuana starts as a seed. What looks like a pebble is actually an entire plant conveniently stored with a few days supplies of food to support itself. During germination, this food is converted into sugars that the plant uses to break through its shell and form its roots. From that point forward, the young seedling depends on its environment to provide the nutrients it will need to survive.

Germination brings a seed out of its slumber and triggers the growth process. A seed will begin germinating once it receives enough moisture.

At that point, it will increase in size and break open its shell. A germ opening forms and a root will emerge, which will help the plant absorb nutrients from the earth.

Nature and gravity ensure that the root grows downwards and the stem upward, creating a young seedling that can survive off light and earth.

Since all marijuana grows from a cannabis seed, many people want to know how to identify a healthy seed.

Honestly, it is difficult to tell if a plant will be healthy based on its seed alone. There are, however some tell-tell signs.

Generally speaking, a pale-green, white, or very dark marijuana seed may have trouble germinating well. But this does not always reflect the outcome of the plant and is always worth trying.

If you are unable to use all of your seeds, store them in a cool, dark and dry place until you can. A refrigerator is ideal.

Planning for germination

Seeds are designed to germinate, but they are more likely to do so if given the ideal environment. There are many methods of germination, but they will all require:

  • Moisture to help the seed expand and break through its shell
  • Minimal interference so that delicate structures aren’t accidentally broken that mimic springtime (between 20°-22° Celsius or 68°-72° Fahrenheit)

If you remember these three things, your germination attempts are more likely to be successful.

It should go without saying that successful germination is important. Your seed is the foundation for your plants – which is why many successful growers choose to start with high-quality seeds.

You can also improve your germination attempts (and possibly speed up the process) by soaking your seeds in 1% hydrogen peroxide or a compost tea solution for 12 hours before using them. This process will kill any infectious agents.

3 Simple ways to germinate your seeds

The best germination method is the one that works for you, and if you are like me, you’re going to want something simple and natural.

My favorite way to germinate seeds is a 24-water soak followed by soil germination, but something else may work better for you. Here are three of the easiest ways to germinate seeds.

Germinate seeds directly in soil

Planting your seeds in the soil that you intend to grow in is the most common and often, most successful method of germinating marijuana seeds.

This method is perfect for ensuring young seeds have minimal interference since the fragile root is protected by the soil. It’s also the most natural way for marijuana plants to grow.

How to plant marijuana seeds directly in soil

The first step in learning how to plant marijuana seeds directly in soil is to first make sure you use the right type. Use mildly fertilized potting soil or a seed starter. It should have a pH of approximately 6.

This type of soil will have spores and minerals that help young marijuana plants thrive. Do not add nutrients – potting soil has enough nutrients for at least the first two weeks of the plant’s life.

If you add any more nutrients, you risk killing your seedlings due to a nutrient overdose. Place your soil in a small pot.

Steps to germinating cannabis seeds

To prepare the soil for your seed, push your finger into it to create a small hole that is up to 1.5cm (0.6 inches) deep.

You can also use a pen or pencil.

  1. Place one seed into the prepared hole and cover it with soil. If you’ve already germinated, the seed will have a root – place the root facing downward (more on that later).
  2. After you’ve covered your seed with loose soil, do not mess with it.
  3. That includes pushing it down further – this will happen naturally as you water it.
  4. Use a plant sprayer to moisten the soil and place the pots under a fluorescent lamp.
  5. Don’t use a windowsill, because the temperature is not stable enough for germination.
  6. The temperature of the soil should be 22° Celsius or 72° Fahrenheit which is easy to achieve with lighting.
  7. Keep monitoring your soil to make sure it stays moist.
  8. Within a week (or as little as 4 days) you should start seeing stems emerge from the soil. You now have a seedling!
  9. Once your plants are 2 to 4 inches tall (5 to 10 centimeters), transplant your plants into a larger pot with the stems further in the ground. Your plant will now have many roots that will support it for the rest of its life.

Germinate seeds in water

As I mentioned above, germinating in water is my favorite way to start my seeds.

It may seem like a bad idea, as there are more water and light than recommended when using this method, but it works! I’ve found that it is around 90% effective.

The “trick” is not leaving the seeds in water too long.

Usually, 24 to 48 hours is enough for the seeds to show their tail, but you can leave them soaking for up to 7 days without too much of a worry.

Water germination

Water germination is useful because it assures that there is the right amount of moisture to begin germinating.

If done for just a short period, it can help crack open the shell, pre-sprouting the plant right before your eyes.

Water germination shortens the process by making it easier for the plant rather than having to push through the soil.

  • To germinate with water, fill a glass with tap water and allow it to reach room temperature over a few hours.
  • The temperature should be around 18° C or 65° F. Do not add nutrients. Drop 2 to 3 cannabis seeds into the water and watch for any changes.
  • Refill the glass with fresh water every other day while maintaining its temperature.

After about 2 to 4 days the seeds should start to split.

You can place your seeds in the soil at any point, but once the roots are 3 to 5 mm (.1 to .2 inches) long, they must be planted.

These are the basic instructions from my store that I share with new growers:

As much as I prefer to germinate my seeds in water, it does have its downside.

At some point, you will need to handle your seeds, and this is risky. Germinating seeds are delicate, and the roots are especially fragile. If you harm them in any way, your plant might not develop well.

Be very careful when placing your sprouted seed into the soil, and if possible place the root facing down.

Germinate with cotton pads or paper towels

Another easy way of germinating your seeds is to use cotton pads or paper towels.

This is a common way of doing it because cotton pads or paper towels can keep the seeds moist and protected.

See also  Amazon Cannabis Seeds

While cotton pads (or balls) or the best for this method, cheap, non-porous paper towels will work as well.

Just make sure they are plain single-ply paper towels – the cloth-like ones may cause your roots to grow into the towel.

  1. To germinate using cotton pads, place a few seeds between two cotton pads and moisten with a plant sprayer.
  2. When using a paper towel, place the seeds in between two paper towels and store the towel-cushioned seeds in between two plates, under an upside-down bowl or in a plastic bag.
  3. Keep the temperature around 22° Celsius, or 72° Fahrenheit, and (once again) do not place the seeds on a windowsill.
  4. In about 2 to 5 days, the seeds will start to split open, and a tiny root should appear.
  5. Place them in the soil when they are 3-5 mm or 0.1- 0.2 inches long.

Like the water method, germinating this way has its risk. If you are not careful, you can damage fragile roots while transporting them to the soil. You can also tangle the root in the wet paper towel if you are not extremely careful.

Explore the beginner cannabis seeds in my shop and start germinating your first seeds!

Use your fingers or tweezers to move delicate sprouts, and don’t allow the root to grow too long before moving it into the soil.

Other germination methods

Water, soil, and cotton pads or paper towels are the easiest ways to germinate your seeds, but they aren’t the only ways. You can also use starter cubes or plugs for germinating cannabis seeds. Simply drop the seed in, add water, and wait for it to germinate.

They aren’t always as successful, but they eliminate the risk of damaging your root when transporting a young sprout to its final growing home.

Below are two types of starter materials that can safely germinate your seeds.

Germinating seeds in rockwool

Rockwool provides the perfect environment for germinating seeds.

It is mineral wool that is made from volcanic rock and other materials (such as basalt and limestone). Rockwool is man-made by melting its ingredients into molten lava that is quickly spun into threads. These threads are then compacted, cured, and cut.

Rockwool is an ideal growing environment, but it will need to be amended slightly for marijuana plants.

First of all, you will need to add some fertilizer before you use it to start seeds. The TDS should be around 600ppm. You’ll also need to lower the pH since Rockwool has a pH of 7.0, which is too high for germination.

To lower the pH, soak Rockwool plugs in water for at least a day. Since water has a pH of 5.5, this will bring down the pH.

It should also be noted that there are some serious drawbacks to using Rockwool.

Because it does not occur naturally, it’s not the best for the environment.

It’s also not the greatest for your health; wear gloves and cover your mouth and eyes when handling this stuff.

Because of the extra steps involved (such as adjusting the nutrients and pH) and handling issues, this method is not recommended for beginners, although it is not terribly difficult to do.

You’ll need to purchase and TDS meters for the most successful germination, but outside of that, the material is very affordable and easy to find.

Because it does not require soil, this method is ideal for those who plan to grow hydroponically.

Germinating seeds in peat pellets

Peat pellets are another way to germinate seeds without the risk of damaging young roots.

Peat pellets are compressed peat, which is made of partially decomposed vegetable matter and is simply yummy for young plants.

The pellet enlarges when you add water to it, forming a container of nutrient-dense soil alternative around germinating seeds.

Unlike Rockwool, peat is already optimized for cannabis germination.

It has a pH of 5.5 and a TDS of 625, so you don’t have to worry about making any adjustments. The only preparation required is soaking the pellets in warm water.

Once the roots become visible, (by popping out of the peat), simply move the entire pellet into the soil, rock wool, or coco coir, where it will continue growing.

This type of germination is not recommended for hydroponic setups.

Peat pellets have a good germination rate, are easy to use, and are suitable for beginners. They are also ideal for cloning.

I recommend the Jiffy brand of peat pellets which can be purchased on Amazon.

Germination environment

In addition to the material used to germinate your seeds, the grow environment you provide will play a huge role as well.

Your seeds will need the correct temperature and levels of moisture to sprout into a strong, healthy plant.

“Weak plants are the result of weak seeds and poor growing conditions.”

Jorge Cervantes

Below are some tips for creating the perfect germination environment.

How to water sprouting seeds

Watering is essential throughout the cannabis life cycle, and germination is no exception.

Not enough water and your seeds do not germinate, too much and that root doesn’t survive.

Excess water keeps oxygen from the roots and can attract mold, which is why you have to be very careful not to overdo it.

When germinating weed seeds indoors using soil or another growing medium it is relatively easy to monitor the water levels. You should water your seed until you see water dripping out from below (and not more).

Even though the seedling cannot absorb that much water, it will evaporate quite quickly, so you need to make sure there is always enough around.

If you water it until it reaches this point, it should supply enough moisture for a few days.

Lighting and temperature

Like water, lighting is essential to a cannabis plant. In a mature plant, light enables the plant to form sugars from carbon dioxide and water.

Buy feminized seeds

  • High-quality feminized seeds
  • Guaranteed germination
  • Incredible high yields
  • F or grower’s of all experience

The plant then uses those sugars to power its growth – something we humans call photosynthesis.

For a seed, lighting is important as well because it provides heat, which a seed needs to push open its shell and send its root into the earth.

The best way to give your seeds the temperature it needs is with fluorescent lights. (T5 high output with a color temperature of 6500K).

Fluorescent lights are ideal because they do not use too much power, and they don’t give off too much heat.

You can place them as close to a young plant as you need, and although your seed doesn’t need it at this point, it will as soon as those first leaves start peeking out from the top of the soil.

Incandescent bulbs can also be used because they are great at generating heat. You can’t use them as grow lights, but for germination, they work just fine.

You can also use a seedling heating pad (available at most gardening stores). These heat the seeds from the bottom instead of the top. They will not be enough once your plant has started growing, however.

Keep the temperature of the soil around 72 degrees.

Seeds germinate best in warm, humid temperatures, similar to springtime.

To create a humid environment, wrap plastic wrap around your pot, creating a biodome for your plants. Just remember to remove the plastic wrap the minute you see any sprouts emerge from the soil.

If the soil, or water, or whatever you are growing in is hotter than 72 degrees Fahrenheit, move the lamp further away from the plant.

Dry air won’t kill seedlings, but if you can reduce it, even better.

Where to germinate seeds

When you’re planning your outdoor grow and you received your seeds, it’s best to germinate them indoors. This is because indoors it is much easier to maintain the correct temperature, water levels, and light exposure.

Even if you plan to grow your plants outdoors, you do not want to try starting them outside (unless you absolutely need to).

Outdoors you must worry about rain, clouds, and plenty of other things that could keep your seeds from sprouting.

You’ll also have to wait until the final frost has passed, meaning your growing season may be delayed compared to if you had started the seeds inside.

Starting indoors gives you a head start and your plants a better chance at survival.

If you still plan to germinate outdoors, choose a location that will support the plant its entire life. You will not be moving the plant so choose wisely.

  • Plant seeds when corn is typically planted in your area.
  • Dig 6x6x6 holes at least three feet apart and fill them with potting soil.
  • This will give the seeds enough nutrients to start.
  • Then, dig a small, quarter-inch deep hole into the potting soil and drop the seed in.
  • Soak that soil with water, and water it again in a few days if the weather is warm enough.
  • You can use row covers to protect your seeds and keep the area warm but be careful to not leave them on too long – young plants will need the light once they break through the soil.
