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.

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!

Ready to sprout!

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.

Germinating Marijuana Seeds in a Water Cup

We have seen many methods of growing marijuana seeds. From the most basic to the advanced technique, cultivating marijuana is a well-loved hobby for beginners and experts alike. With various methods on how to germinate marijuana seeds, it all just comes to your preference on what type to use.

Why You Need to Germinate Marijuana Seeds

Marijuana germination is the procedure where a sprout breaks out of the seed’s coating. The sprout looks like a small white tendril and it is extremely delicate. It is the plant’s initial root and it is often referred to as the “taproot.” All the upcoming roots created by your marijuana plant will grow from the taproot. This means that the taproot is the building block of all your plant’s potential roots in the future.

The taproot, together with a few other tiny young offshoots around it – will grow and develop into longer and stronger roots. They will push the seed above the ground until the shell emerges from the surface of your growing medium and grow its first leaves known as the “cotyledons.”

These initial round leaves will sprout from the inside of the marijuana seed. The cotyledons developed as part of the plant embryo in the seed, which means there’s no need for the marijuana seedling to grow them. The sprouting first leaves are the ones that break open the shell after the taproot cracked it open.

How to germinate marijuana seeds

Marijuana seeds need three things to achieve successful germination and these are heat, water, and air. Using these, you can perform the simplest and easiest technique to germinate your seeds. But first, you’ll need paper towels, two clean plates, and marijuana seeds.

Here’s the process of this germination technique:

  1. Take your paper towels and soak four sheets in the distilled water. The sheets should be saturated with water but they shouldn’t have any excess dripping water.
  2. Get two sheets of the saturated paper towel and place them on one plate. Then, arrange the seeds on top of the plate with at least one inch of space between them. After that, get the remaining sheets of paper and cover it on top of the seeds.
  3. You need to make a dark protected area for your seeds. You can do this by covering the top with the remaining plate. This will create a dome-like space for your seeds to germinate.
  4. Lastly, keep the area warm and follow the correct temperature between 70-90°F.

These are all the steps to germinate your marijuana seeds. Once you completed each step, you only need to wait.

Don’t be impatient because this stage is crucial for the overall growth of your plant. Make sure you check the paper towels from time to time. If the papers are starting to lose their moisture, spray a little amount of water. Maintaining the proper amount of moisture around your seeds will keep them healthy and happy.

Note: each seed has different germination speed. Some may take longer than the others and that’s normal. You can tell that your seed has germinated once it breaks and one sprout begins to emerge from it. This sprout is the taproot of your seeds and it will be its main stem. Once you see the taproot growing from the seeds, that’s the indication that your germination process is successful. By this point, refrain from touching the seed or the taproot since it can disrupt their development.

Proper Way of Transplanting Germinated Marijuana Seeds

When the germination stage passes and your marijuana seeds have grown their taproot, it’s time to transplant them to a growing medium of your choice. Just like how you treat your seeds during germination, you also need to be extremely careful when transplanting your little plants. Remember, they are not yet fully-grown which makes them powerless against stressful factors.

Follow the steps below to properly transplant your germinated marijuana seeds:

  1. Prepare the growing medium in which you will transfer your germinated seeds. You can start with small 2-inch pots since they are cheap and easy to access. What you need to do with the pots is to fill them with coarse and light potting soil. Then, place a hole in the middle, which is at least a quarter-inch down the soil using a pencil or pen.
  2. When your growing medium is ready, it is time to transfer the seeds. Using a pair of tweezers, slowly pick up the seeds and place them in your growing medium, specifically inside the hole. Make sure its taproot is facing downwards. Then, gently cover it with soil.
  3. Next, you need to water the soil using a spray bottle. This will provide moisture in all areas of the soil without the risk of drowning your seeds. Remember that you should only provide sufficient water to your seeds because overwatering them can kill the little sprout.
  4. Lastly, you need to check the moisture level and temperature of the soil to maintain the good condition of your seeds. After a week, you can expect the seedlings to start appearing in your growing medium.

Germinating Marijuana Seeds in a Water Cup

If you want a cool, new method to germinate your seeds, the following has a 100% success rate. Though the results may vary, just like what usually happens to the all-natural growing method, this one is easy which is perfect for first-time growers.

First, you need the following materials before you start:

  • 1 plate
  • a glass of distilled water
  • paper towel
  • tweezers
  • pill bottle

A little reminder before you start with the method is you should always use distilled water.

  1. Never utilize tap water because it carries impurities that might harm your seeds. Lastly, see to it that your germinating space is situated inside an enclosed room that has a temperature of 18 to 25 °C. The following are the steps to follow on how to germinate marijuana seeds in a water cup:
  2. Place your seeds inside a cup or glass of distilled water. Some will instantly drop to the bottom while others will float. Leave them for a few hours until their shell is penetrated with water and then push them to the bottom of the cup/glass using your fingertips. Allow the seeds to soak for 15 – 18 hours. The soaking process will moisten the shell of the seeds which makes it easy for them to germinate.
  3. Get a thick dye-free paper towel and place it on top of a plate. Place the soaked seeds in the paper towel and position them with enough spaces around each other. Fold the paper towel to envelop the seeds.
  4. Place it in a warm and dim area until the seeds start to crack. Make sure the seeds are well-moisturized so check it every 5-12 hours and use a spray bottle to add water onto it.
  5. Be patient. Seeds may take seven days or longer to germinate. Remember that each seed has a different germination phase.
  6. Once the taproot begins to appear, you can transplant your germinated sprouts to your desired growing medium. Make sure the taproot is facing downwards when you plant it.

Most marijuana seeds take 1 to 2 days to germinate, while others take a week. This depends on the thickness of their shells. Each seed has different features and physical characteristics, hence the difference during the germination process. If you follow all the steps of the germination method we mentioned above, you can expect 80% success rate.

Conclusion

Knowing the right way of germinating your marijuana seeds is vital in starting your weed production. You can choose from all the methods we have provided above. Just make sure that you give your plants everything it needs including food, light, and water. They should also be kept in a growing space with proper levels of humidity and temperature.

Establishing an ideal environment for your plants will help you avoid obstacles along the way. Above all, be organized and precise. Place your seedlings, seeds, and clones in a clear jar and label them. This will help you avoid confusion and expensive mistakes as you learn how to germinate marijuana seeds. Now go and get your pot production going!

Germinate Seeds in cup of water.

I was going to just put my seeds in a cup of room temp water to germinate. But ive read that this is not a good idea, because if the seed is in the water for over 24hours it gets no oxygen. Causing the seed to not crack open. Has any one had success with this method? It seems like an easier way then the paper towel method

THis is the only method I use. I let them soak until I see a long taproot. I used to just wait until I saw a taproot crack, in say 18hours, but the last few seeds I just let go a coupke of days and let these mega taproots grow. I then popped them into rapid rooters and a day later I have advanced seedlings rooted and fine. I am pleased. The paper towel method is bad, it means that little root hairs will get stuck to the paper towel and get stressed or damaged and also their is so much that can go wrong there and the worry over heat and cold is there where as with the cup of water nothing ever goes wrong. Hot or cold it always works.

lol, ah a class. I get 100 percent germination this way. I had lost some seeds before using the paper towel or just popping them into media. No paper towel is needed with the cup of water. Just dark. I, in fact use plain tapwater straight from the faucet. Not cold not hot. Then place them in the dark. Traditional knowledge says that when they sink they are ready to go into soil, rapid rooter, rockwool, etc, etc. However, I dont mess with that and simply wait until I thinj the taproot is out far enough for how I feel that day, lol. That simple.

Rapid rooters are a gift from god. Or whoever it is that makes them. Very nice. Google `em. Very cheap and very handy. A coco peat or something material that is meant for hydro or soil. I have used them succesfully 100 percent of the time for both. No lie. They are also the perfect cloning medium.

When a seed has the taproot I use tweezers and place it into a rapid rooter cube or cone. Then I take a little peice of anything handy and gently cover the whole in the rapid rooter cube. The seed needs darl to keep sprouting and take root. After a day or two tops the seed will be poking out. Then just let it go.

Here it gets tricky about half the time. Because the seed does not half to push thru dirt the shell is usually stuck so a little very very very areful nuding is sometimes needed or the plant will die in the shell. It is Very obvious when this happens and what needs to be done and is actually pretty fun to do. SO dont stress. Also I like to put a clear plastic cup over the rapid roooter or the patch of dirt I bury the germed seed to keep the humidity up.

Keep the rapid rooter soaked. Keep the dirt wet too. Whatever you use. Rapid rooters are impossible to overwater. If you sprout in dirt be careful and just wet the the toplaer so as the seed stays moist.
