Germinating Cannabis Seeds – A Step by Step Guide

Germinating cannabis seeds is one of the most exciting parts of the whole grow. It is almost magical to summon new life from a dormant seed; however, it can be very frustrating when things don’t go well. In this article, I explain how to germinate cannabis seeds successfully. I begin by reviewing the science of germinating cannabis seeds. I then describe several common cannabis germination strategies and share some cannabis germination tips and tricks. At the end of the article, I provide my step-by-step guide to germinating cannabis seeds. Be sure to watch my Germination Tutorial on YouTube!

Germination will always be exciting, but it does not need to be intimidating. There are many ways to germinate cannabis seeds successfully. Understanding the science and the shifting needs of the developing plant will allow you to choose the germination strategy that is right for you.

The Science of Germinating Cannabis Seeds

Cannabis seeds are among the easier seeds to germinate. They are large dicotyledon seeds that store a reasonable amount of energy for early life. Furthermore, cannabis seeds do not have any significant seed dormancy factors to overcome. If they are viable seeds they will germinate easily when exposed to the correct conditions.

Seeds become Sprouts During Germination

This may sound obvious, but it is important to consider because seeds and sprouts are different. When the cannabis seed is still a seed, it is resilient and does not depend on ideal conditions to survive. However, sprouts are different. As soon as the seed cracks open and exposes the radicle (tip of the root) it becomes a sprout. As a sprout, it becomes much more sensitive to external conditions. Whereas the seed only needs warmth and moisture to germinate; the radicle on a sprout needs warmth, moisture, oxygen, and darkness to survive and grow.

Germination Stage 1: Imbibition

The seed’s journey to planthood begins by getting wet which starts the process of imbibition. Imbibition is similar to rehydration. When wet, the testa or seed coat of cannabis seeds imbibe water which causes them to swell and soften. The force of water entering the cells in the testa physically ruptures the seed coat and allows the radicle (root tip) to escape. The imbibition of water also activates the metabolic activity within the seed protoplasm.

Warmth is Required for Metabolic Activity

The metabolic activity within the seed will only activate if the temperature is in the appropriate range. Like other seeds, cannabis seeds will not successfully germinate if the temperature is too low or too high. Room temperature is warm enough to allow germination, but warmer temperatures enable more metabolic activity and faster germination. The ideal temperature range to germinate cannabis seeds is 80-86 F (27-30 C).

Germination Stage 2: Respiration

Seeds carry stored energy to help power metabolic activity and growth until the plant can begin photosynthesis. However, just like humans and other animals, plants must engage in respiration in order to convert that stored energy into active energy that the plant can use. During the earliest stages of metabolic activity as the seed awakens from dormancy, the respiration is anaerobic or without oxygen. However, the sprout needs to quickly begin using oxygen in aerobic respiration to continue to survive and grow.

As metabolic activity resumes, the sprout will begin to grow. Cannabis seeds store most of their energy in their cotyledons in the form of starches and proteins. The plant uses energy from aerobic respiration to digest these starches and proteins into simple sugars and amino acids, which it mobilizes to grow the radicle (root tip) and hypocotyl (stem).

Cannabis Sprouts need access to both water and air

Seeds can be completely submerged in water during the first part of imbibition. However, if they are completely submerged after the radicle is exposed then the sprout will die from lack of oxygen. As soon as the seed cracks open and exposes the radicle it needs to have access to oxygen for aerobic respiration. This means that it needs some contact with air. However, it also needs continuous contact with water. To achieve the best results in the sprout and seedling stages it is best to use a grow media that will trap both air and water. As I explain below, paper towels work well for this during the early sprout stage and germination media like Jiffy Pellets or Rockwool cubes are perfect for young seedlings.

Germination Stage 3: Orientation

At this stage of germination, the plant must orient itself to grow properly. The radicle must push down into the soil or media and the hypocotyl must push the cotyledons (first leaves) up out of the soil or media. Both gravity and light help orient the plant to grow in the proper direction.

Apply Light but Keep the Radicle in the Dark

Cannabis seeds do not require darkness to germinate. However, the radicle is sensitive to light. Bright light will stunt the radicle and can lead to a failed germination. When seeds are germinated in paper towels it is best to keep the sprout in total darkness until the radicle is about half an inch long (about 1.25cm). However, as the cotyledons emerge from the seed casing, they will be looking for light to indicate the direction they need to grow. Therefore, when the radicle is longer than half an inch it should be placed in media which will protect it from light. Once the radicle is safely in the media, light should be applied to the top of the media to signal the direction of growth for the cotyledons.

Germination Stage 4: Photosynthesis

During the germination stage the plant relies exclusively on stored energy from the seed. This energy is limited, so the plant must quickly begin producing its own energy through photosynthesis. The young plant works to establish its radicle in the media and push the cotyledons up into the light to begin photosynthesis. Once the cotyledons open and receive light, the plant will begin photosynthesis. At this point, germination is complete, and the plant can start producing its own sugars, starches, proteins and fats.

Nutrients for Germinating Cannabis Seeds

The nutrients and supplements that we provide to our plants are not their food. Nutrients and supplements support photosynthesis. Therefore, they are not needed until the plant has begun photosynthesizing. Indeed, adding nutrients to the water used for imbibition can actually inhibit germination. It is best to use plain water at a neutral pH (7.0) to imbibe the seeds.

Once the cotyledons are open, the plant can use very small doses of nutrients. However, it is easy to overdo it and burn the plant. When and how to begin fertilization depends largely on the media that you are growing in. If you are growing in coco or other inert and unamended media, be sure to read “How to grow cannabis seedlings in coco coir”.

Cannabis Germination Strategies

There are many viable ways to germinate cannabis seeds. Different germination strategies may be more suitable for different growers. Therefore, before explaining my step-by-step guide to germinating cannabis seeds, I will review some of the more popular germination strategies.

Soaking Seeds

Many growers begin germination by soaking seeds in water. This allows for faster imbibition of the seed because it is surrounded by water. It is a safe strategy to follow as long as you remove the seeds from the water before the seed actually cracks open. If you soak seeds, you should use plain (low EC) water with a neutral pH (7.0). Filtered or distilled water is best.

The Paper Towel Method

This seems like a make-shift hack, but wet paper towels provide an excellent air/water ratio for germinating seeds. They also allow you to precisely control the temperature of the seed/sprout during germination. As a result, using paper towels can speed the germination process considerably.

See also  White Cannabis Seeds

The paper towels should be fully saturated with water, but not dripping wet. I like to fold the paper towel so that there are two layers below and above the seed. You can then place the paper towels in an air-tight container to prevent them from drying out. I use pyrex containers. If you use a plastic bag, just make sure that you trap some air in the bag (don’t squeeze all the air out). The radicle does need some air, but there will be plenty, even in a sealed container. Place the sealed container someplace warm and cover it to protect the radicle from light.

The main drawback to the paper towel method is that it is possible to damage the young sprout when you transfer it to media. There are some easy practices to mitigate this risk. First, use cheap, single-ply paper towels. This prevents the radicle from growing between the plies. Second, place only one seed on each paper towel. This allows you to pick up the whole paper towel and avoid touching the sprout when you transplant to media. Finally, don’t keep the seeds in paper towels for too long. Once the root has grown to about 0.5in or 1.25cm, it is time to transplant it to media.

Fail-Proof Cannabis Germination Method in Soil or Coco

We have a cannabis seedling germination page that includes everything you need to know about all the different germination methods, but this tutorial is different. In this tutorial, I’m going to share exactly how I do my seeds from beginning to end. Just follow these instructions and you’ll end up with healthy, fast-growing plants that germinate in just a few days. It’s basically fail-proof.

Turn your cannabis seeds…

This step-by-step tutorial will teach you how to germinate seeds and provide basic seedling care

Soon you’ll have healthy cannabis plants to admire

Supplies Needed

1.) Get Cannabis Seeds

There are a few different ways to get cannabis seeds, with the most common being ordering seeds online and growing seeds you find in weed that you buy. Learn how to research and find the right strain.

Here’s a picture showing several healthy and viable cannabis seeds

2.) Prepare Your Soil or Coco Containers

Before you start germinating your seeds, set up your soil or coco. It will still be a few days until your seedlings arrive, but you want to have everything ready before the seedlings need to be planted.

Get your containers ready before you start germinating

3.) Germination

When it comes to new growers, it seems like the most fool-proof method (at least for me, and many of the new growers who write in) is the Paper Towel Method! It’s so simple, but there’s something about wet paper towels that a young seedling loves Learn About Other Ways to Germinate Seeds.

Paper Towel Method – Place your seeds inside a folded wet paper towel (Important: use cheap brand!)

This method is hard to mess up if you follow the instructions. Place your seeds inside a folded wet paper towel, and put that between two plates. The purpose of the plates is to prevent the seeds from drying out. Don’t let any part of a paper towel hang out the edges or it will wick away all the moisture and dry out. Keep everything totally contained between the plates.

Surprisingly, the really cheap paper towels work the best because the seeds and roots lay on top without getting stuck to anything. This is important. The more expensive “cloth-like” paper towels (like Viva brand) aren’t good for germination because the roots actually grow into them instead of laying on top.

Wet a paper towel (use the cheapest brand you can find). If growing multiple strains, you may want to label the paper towel so you know which is which. Place each seed on the wet paper towel next to their label.

Cover with another wet paper towel

Add another plate on top to keep the paper towels from drying out. Make sure now paper towel is sticking out the sides.

Tips

  1. Check on your seeds every 24 hours but try not to disturb them. When they’ve germinated, you’ll see the seeds have cracked and there are little white roots coming out.
  2. They should germinate in 1-4 days, though some seeds can take 7 days or longer (especially older and smaller seeds).
  3. Keep them warm if possible. Seeds germinate a little faster is to keep them in a warm place (75-80°F). Some people use a seedling heat mat but in most cases that’s unnecessary. I leave mine near a sunny window. I usually put a thermometer in the same place to make sure it’s not too hot or cold (or just check the plate with your hands)

Here are those seedlings about 2 days later. Be extra careful when removing the paper towels. Don’t let the seeds roll around or you won’t know which is which. This is when you’ll be glad you used cheap paper towels, as they are much easier to peel off without disturbing your seedlings.

You can see some of the seeds sprouted, but some of them haven’t yet. That’s totally normal! Each seed is different. If this happens to you, you have two choices. You could plant the ones that have already sprouted and let the other ones stay in the paper towels until they germinate. Or you could just put all the seeds in Rapid Rooters now, and hope for the best as far as the slow-sprouting ones. It’s up to you. Letting the unsprouted seeds stay in the paper towels longer improves the germination rate in my experience, but it’s simpler (easier) to move them all at once.

Seeds often germinate at different rates even if they get the exact same conditions

4.) Place Germinated Seed in a Rapid Rooter

Now it’s time to get your Rapid Rooters! Alternatively, you could place your sprouted seeds directly in the final growing medium (coco or soil). I think these help them get started, but I’ve grown many successful plants by just putting the germinated seed directly in its final home.

Rapid Rooters are nice, but not necessary

The Rapid Rooter should be cut open lengthwise. I use big scissors but you could also use a knife.

Gently place the germinated seed inside, root down. Place the seed close to the surface so it doesn’t have far to go.

If you have a root that is curved or bent, don’t try to straighten it out. Open the Rapid Rooter and lay the germinated seed down gently. It will naturally lay on its flattest side. When you slowly close the Rapid Rooter, the bent parts of the root will end up in the “crack” of the Rapid Rooter that you cut to split it open from the side.

Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened. I love Rapid Rooters because their texture causes most seeds to stay in place and not “fall down” further into the hole once you’ve got the Rapid Rooter closed.

5.) Water the seedling in the Rapid Rooter until you see a root come out bottom, 1-2 days.

Make sure to always keep the Rapid Rooter moist but not soaking wet and give plain water.

Since your seed has already sprouted and been in placed into the right growing position, it’ll often pop its head out within just 12-24 hours! Sometimes you see just the leaves, but often you actually see the seedling push the shell above ground.

Don’t touch the shell if possible because a tiny tug in the wrong direction can pull the seedling out of the plug and break off the taproot.

Try to let the seedlings break free if possible. But if you have a seedling that’s stuck in a shell after a day or two, and doesn’t seem to be getting any better, you need to go in and help.

I’ve found that pointy tweezers are perfect to pry open a shell that’s stuck. Just close the tweezer, stick it inside between the shell halves, and let it slowly open to pull the shell apart without you ever touching the seedling.

Sometimes a “film” from inside the shell gets stuck on the leaves. If that happens, try putting a drop of water on the film a few times a day to soften it. If the seedling doesn’t push it off on its own, hold the stem between your fingers (so it doesn’t pull at the root) and use tweezers to gently tug at the membrane and release the leaves.

Don’t use a dome on seedlings unless it’s very dry where you live. If you do use a dome, consider keeping a vent open and watching the humidity. A young seedling doesn’t require as high humidity as clones (which are what the domes are designed for), and seedlings tend to get “wet feet” and stop growing as fast in constantly wet conditions.

Water your seeding in the Rapid Rooters until you see a root coming out the bottom. Keep Rapid Rooters moist but not wet. During this time, give seedlings bright filtered light. A CFL or LED light bulb kept several inches away works well. I’ve left mine on the kitchen table next to a sunny window, and that’s also worked fine for me as long as it doesn’t get too hot.

You should see a root come out the bottom in just a day or two!

After you see your first root, it’s time to…

6.) Put Seedling in its New Home

You are about to water your seedlings for the first time, so prepare your water now.

  • Coco – Prepare water with seedling-strength nutrients, and make sure to pH your water to 5.5-6.5 right before giving it to plants. Unlike soil, coco does not naturally contain any nutrients so you must provide nutrients in the water from the first watering.
  • Soil – Prepare plain water at 6-7 pH. You don’t need to add nutrients for the first 3 weeks or so because your plants will live off what’s in the soil. Adding extra nutrients at this point might overload and burn the seedlings.

Now that your water is ready, dig a hole that’s a little smaller than the Rapid Rooter, and place your seedling plug inside. The idea is to let the Rapid Rooter stick up above the soil a little to help the roots get more oxygen. It’s okay if the plug goes in flat with the soil, but don’t bury the stem as that can cause stem rot in some cases. Even if you’ve got a tall seedling, you usually won’t notice the extra length once the plant is bigger.

Gently pack the nearby soil/coco to hold the Rapid Rooter in place so the seedling is stable.

Your seedlings get a little extra oxygen if you let the Rapid Rooter stick up into the air slightly as opposed to burying it.

Example of cannabis seedlings growing in coco coir, about to get seedling-strength nutrient water. If they were in soil, I would give plain water for the first few weeks.

Water immediately in a small circle around your seedling. For most grow mediums and containers above 1 gallon, you can give 2 cups (500 ml) of water immediately without overloading your seedling. If the grow medium feels moist (for example coco that was recently re-hydrated), give 1 cup (250ml) of water this first watering.

Give 2 cups (500 ml) water in a circle around the seedling. If the grow medium is already wet, give just 1 cup (250 ml)

How to Water Seedlings in the Beginning

Two Main Goals

  • Seedling roots never dry out (most important)
  • Seedling roots aren’t staying soaking wet (roots need oxygen)

Seedlings “drown” and die due to lack of oxygen if they get too much water too often. To avoid this, try to provide an amount of water that lets you water seedlings every few days. Avoid giving so much water that the seedling roots are in a super wet grow medium for days as this causes “damping off” and root problems. Some grow styles like high-frequency fertigation call for watering more frequently. Just remember that the more often you water your plants, the less water you should give at a time. Also, keep in mind that a smaller container tends to dry out fast while a bigger container holds onto the water for longer

Try to maintain a schedule that lets you water your plants every few days without them looking droopy

  • Water in a small circle around the base of the plant at first
  • If the growing medium feels dry within 1 day, give more water next time. Otherwise, give the same amount again next time you water
  • Repeat, until you can give enough water to get at least a little runoff, and have it dry in a few days

If the medium is drying in less than 2 days, it means you need to give more water to the plant at a time, or possibly transplant to a bigger container if the plant has outgrown its current one.

If your growing medium takes longer than 3 days for the top inch to dry, it means the soil is staying wet too long, and plant roots aren’t getting enough oxygen. It also puts your plants at risk of getting fungus gnats . Try giving less water at a time until the plant is drinking more. It’s possible you may have a problem with drainage in your medium ( what is good soil? ) or there are no drainage holes so extra water can’t come out the bottom of the container. Always remove any runoff water instead of letting the plant sit in it.

More seedling resources

Some growers like to put seedlings in solo cups and then into their final container. When done right this can increase the rate of growth by providing more oxygen to the plant’s roots. If you go that route, I recommend paper cups as they’re not as bad for the environment.

Autopsy: Why Aren’t My Marijuana Seeds Sprouting?

If your seeds still aren’t sprouting and growing properly, consider the following factors.

If there’s no germination at all…

  • Temperature may be too hot or cold – aim for 75-80°F
  • Too wet – seeds and seedling roots should always be moist, but should not be soaking wet
  • Too dry – if a root dries out the seedling can die
  • Bad seeds – It might not be you, it could be the seeds themselves. Even if you purchase from a good breeder, sometimes you still get duds. How can I tell if seeds are viable?

If seeds sprout, but then stop growing…

  • Temperature is too hot or cold – aim for 75-80°F
  • Too wet – new seedlings don’t like “wet feet” so make sure your Rapid Rooter or growing medium never looks shiny or muddy, as that means there’s too much water! For this reason, it’s also usually recommended to avoid using a humidity dome with seedlings unless your air is dry. Although clones love humidity domes (they need water from the air because they don’t have any roots to get water), seedlings like it a little drier or roots tend to get mushy.
  • Too dry – less common unless you live in a very dry area, but sometimes your medium dries out too fast if you’ve got a heavy-drinking, fast-growing seedling!
  • Too much light – if the seedlings get blasted with high levels of light right away, it can shock them. They may need some time to adjust to higher light levels. Simply starting your grow light a little further away than normal is usually enough. Think sunny window at first, and start ramping up after a week of healthy growth.
  • Not enough light – if seedlings are growing long and stretchy without growing new sets of leaves, it means it wants more light.
  • No light for more than a day – if the sprouted seed doesn’t get light within 24 hours after sprouting, it may die. Once seeds are sprouted, get them in a Rapid Rooter and under at least some amount of light as soon as possible!
  • Roots damaged – If somehow your roots got damaged, it can sometimes stop the seedling from growing

Unfortunately, sometimes you will never know why certain seeds just don’t thrive. It’s all part of nature. But if you follow this tutorial you will get the best results possible.

How To Germinate Cannabis Seeds

Growing your own weed is fairly easy, as explained in our article ‘All You Need For Growing Weed At Home‘. The hardest part for some growers though, is germinating their newly bought cannabis seeds. After all, the vulnerable seedlings are easily damaged. However, making sure your cannabis seeds survive germination is essential for a successful grow. In this blog, we highlight three tested methods that let anyone germinate cannabis seeds with minimal effort.

How To Germinate Cannabis Seeds, Step 1: Get Good Genetics

We cannot stress this enough. If you want good results, you are going to need good materials to start with. In case of growing cannabis, the first thing on that list are good cannabis seeds, of course. Besides high quality cannabis seeds all you need is some water, a warm environment (between 20-25 degrees Celsius) and – lack of – light to start germinating your future cannabis plants.

Even though living weed plants love (and need) a lot of light, germinating cannabis seeds thrive better in a dark environment. And just like there are different methods of growing your own cannabis, there’s also a choice in how to make your seeds sprout.

Want good cannabis? Get good seeds!

Germination is actually a process where you activate a dry seed that is in a ‘sleeping state’. By adding water to the seed, a small root that is inside the seed-shell will want to come out in search for more water. This will make it develop into a big taproot that’ll serve as an anchor for the plant and from which more roots will sprout. Read more about root-development in this article: ‘Clones vs. Seeds: What Grows The Best Cannabis?‘

Germinate Cannabis Seeds In Water

The easiest way to germinate your cannabis seeds is to let them soak in a glass of water. The seed will absorb the water and due this process hormones will make the seed start to grow: expansion and elongation of seed embryo.
You will see them sprout after 24 to max. 48 hours. Note that you need to store the glass of water in a dark place on roomtemperature. After sprouting they are ready to plant in soil, 1cm to max 2cm deep. All they now need is love, light, water and heat!

How To Germinate Cannabis Seeds: Wet (Paper) Towel Germination

The best known way of germinating cannabis seeds is to put them on or between wet paper towels or cotton wool. This method exists in different varieties, as it’s not so much about the paper itself, but more about the absorbency of the material. It’s very easy to make sure the ‘medium’ doesn’t get too soggy and doesn’t dry out easily. If it does dry, you can effortlessly add a few drops of water to immediately re-moisten it.

Wet paper towels are probably the most common way of germinating cannabis seeds

The goal here is to balance out the moisture so it’s not too dry, nor to wet. Go for a piece of paper that is moist all over, but doesn’t drip when you pick it up. If the seeds stay to dry, the root that’s supposed to sprout won’t be able to make it out of its shell in search for water. If the paper is too wet though, the root will come out and quickly stop looking for water; as it’s already soaked in it. This stops the development of the root, delays the growth and might even cause the seeds to rot after a while. So, be careful not to give too much water as this is one of the most common rookie mistakes when it comes to growing weed!

Transplanting In Soil

After the root has sprouted and has gained a few millimetres in length, it’s time to transplant the seedling into its soil and put it under a light-source. As a rule, a small 1cm deep hole made with your fingertip should do. Gently pick up the seeds one by one, taking care not to touch the root. Use a clean pair of tweezers and don’t squeeze. Make sure that the roots don’t cling to the paper or cotton wool. Lovingly cover the seed with a little (loose) soil and add a few drops of water. Now, all you can do is wait whole the story continues below the surface. As soon as the seedling pops her head above the ground and green leaves emerge, she’ll needf light to continue growing.

This is the part where most growers (especially the hasty ones) sometimes lose a seed. Remember that you are handling a baby plant here. The vulnerable root is easily damaged during the transplant. If you don’t trust your steady hands, it might be better to choose another germinating method.

How To Germinate Cannabis Seeds In Soil

Another common method of germinating cannabis seeds, and probably the most natural one, is to stick the seeds directly in their intended medium: the soil. You can do this with or without soaking it in root stimulator for a few hours first.

By planting cannabis seeds directly in their soil or coco – or whatever other medium you might be using – growers cause the minimal amount of stress for the plant. Direct planting also allows the taproot to immediately dive as deep into the ground as possible. Furthermore, its leaves can enjoy the light as soon as they emerge from the developing seed. This way the seedling can start its growth with a fair chance, providing you with a steady, high-yielding cannabis plant.

Cannabis seeds and sprouted seedlings require constant temperatures of around 20-25 degrees Celsius

For this method, simply prepare your medium by moisturizing it, again, without soaking the soil completely. Then take your flower pots and use your finger to make a small hole about 10-15mm deep in the top layer to put the seed in. Cover the seed up loosely and top it off with a little water. Be careful not to give too much at once though! A stream of water can cause the seed to travel further down the pot where it’s too moist – and too deep to travel back up again.

The top layer is the perfect place to germinate cannabis seeds, as it dries out faster than the soil further down the pot. This makes it easier to ensure the right level of moisture for the seed to germinate. If it gets too wet, the seeds will rot in the soil. If it stays too dry, the plant will not be triggered to emerge from its shell. Again, it’s all about finding the perfect balance between too wet and too dry.

How To Germinate Cannabis Seeds in Plugs

Last but not least on this list is the germination of cannabis seeds in special plugs. These plugs are available in various materials, especially designed for quick and efficient germination of cannabis seeds.

Plugs are a practical way to germinate cannabis seeds

Most plugs are dry blocks of (usually) coco fibre. Peat plugs are an interesting alternative, as these contain some initial nutrients to help the seedling along. After fully absorbing about 500ml of moisture, or 250ml of a root booster and another 250ml water, they slowly turn into a moist, soil-like plug. Grow plugs usually have a premade hole in which to place the seed. After sticking the seed in the top of the plug, cover it lightly with a little leftover plug fibre. It takes a few days at maximum before you see the first heads pop. As soon as the roots grow out of the bottom or the side of the plug, you can stick the entire plug, complete with its seedling, into your intended medium. These plugs make germination and the initial transplant a piece of cake.

After Germination: Growing Your Seedlings

So there you have it: whichever method you chose, germination should now be underway. Remember that even the best seed banks work with organic, natural materials, so 100% germination rates can never be guaranteed. If you get your technique right, though, most or all of your seeds should germinate according to plan. Once your seeds have become seedlings, the next steps of your grow await. There’s a lot of choices to make from here to harvest time: indoor or outdoor, which spot to pick, what nutrients to use, and so on.
