Do you want to know what’s the best, quickest and easiest way to successfully germinate your weed seeds at home and what you need? Please take your time to read all the information on this page carefully. In this way you ensure yourself of a successful germination process.

Best way to germinate weed seeds

Although there are several germination methods, not all methods are equally efficient. An example of a less efficient method is for example by planting the seed directly in the soil. Especially since you cannot determine the direction of root with this method and the change of rot. Fortunately, there are different ways that prove to be efficient like the germination in rockwool. Yet the best and most safest way to germinate weed seeds is by applying two different methods one after the other. First the water cup method and then the paper towel method. Both really easy methods which you can do at home.

How to germinate weed seeds in a paper towel?

The germination process of cannabis seeds with the paper towel method consists 5 simple steps. Here’s a short summary:  

  1. Place the cannabis seeds in a cup of lukewarm water and put them in a dark room for 18 to 24 hours. Wait until the seeds start to crack a bit before you apply the paper towel method. 
  2. Put two layers of paper towel on a plate and spray the paper wet with a plant spray.
  3. Pour your seeds carefully on the wet paper towel, place a new paper towel over it and spray the paper wet. Make sure that the seeds are in contact with the wet paper towels. 
  4. Take another plate and place it upside down on the plate with the seeds so that you create a dark space. However, do not exactly align the edges of the plates. The seeds need oxygen to germinate. Check every 5 to 8 hours if the paper towel has not dried out and spray water again if necessary.
  5. Check after 24 hours if the seeds have germinated. If not just let them germinate for another 24 hours. Note: some seeds need 48 to 72 hours to germinate but it can even take 168 hours (7 days). Patience is therefore required. 

How to germinate weed seeds – step by step

Below is an explanation of the above steps. If you stick to our step by step guide you ensure yourself of germinating cannabis seeds in the right way.

What do I need to germinate weed seeds?

For a successful germination you need:

  • Cannabis seeds
  • Paper towel
  • Two ceramic plates with the same size
  • Plant spray
  • Water
  • Drinking cup (glass)
  • Tweezers

Step 1: Soaking weed seeds in water 

For an successful germination, it is important to soak your weed seeds before applying the paper towel method. By pre-soaking the cannabis seeds, the husk of the seed softens and the seed will germinate more easily.

How to do this?

Grab a glass drinking cup and fill it for three quarters with lukewarm water. Then place the cannabis seeds into the cup of water. You will see that the cannabis seeds will float first. Try to push the seeds down gently with the tip of your finger without touching the bottom of the glass. Will the cannabis seeds rise again? Then wait 1 – 2 hours and try again.

Put the glass with the seeds for a maximum of 18 to 24 hours in a dark room with a temperature of 21° to 25°. In the meantime, check if the cannabis seeds are all sunk. Are some seeds still floating? Try pushing the cannabis seeds down again carefully.

What will happen?

Cannabis seeds will sink to the bottom. This happens normally after a few hours. After 14 to a maximum of 24 hours most of the seeds are on the bottom, and some are cracked open. This does not necessarily apply to all seeds. However, do not panic. In step 2 these cannabis seeds are further stimulated to germinate.

Note: be careful with leaving the seeds in the water for more than 24 hours. If you do that, seeds can get a lack of oxygen, drown and rot.

Step 2: Prepare the plate and kitchen paper

In step 1, some marijuana seeds probably germinated a bit. Others possibly not yet. Whatever the situation is, after a maximum of 34 hours you go to step 2 of the germination process.

What to do in step 2?

In this step you need a ceramic plate and two sheets of kitchen paper (paper towel). Kitchen paper is thick enough to retain the moisture, which is very important for the germination of your cannabis seeds.
Take the plate and put two sheets of kitchen paper on it. The kitchen paper must cover the dish or plate entirety. Spray the paper towel completely wet with a plant spray. The paper must be wet, but not dripping wet. You are now ready to proceed to step 3.

Step 3: Place the cannabis seeds on the wet kitchen paper

Before placing your pot seeds on the wet kitchen paper, the cannabis seeds are still in the glass with water. Depending on the glass, you may have a lot of water in it. Therefore, carefully pour ⅔ of the water out of the glass. Be careful not to wash the seeds down the drain. A colander is therefore recommended.

What to do in step 3?

Leave the pot seeds in the glass with about 1 cm of water and carefully pour them out onto the center of the kitchen paper. Carefully pick the seeds up with a tweezers and place them on the center of the edge slope. Place the blunt end of the seeds, the tip without point, on the paper towel and make sure there is a space of 1.5 cm to 2.5 cm between the seeds. In this way you prevent their roots from becoming entangled. Do you have insufficient space on one plate? Then use two plates.

Note: try to place the seeds in place with as little contact as possible. The less you touch the seeds, the smaller the chance of damage. Besides, never touch the roots.

Are all the seeds neatly in place? Then grab another double paper paper. Spray the kitchen paper a little damp and place the paper over the first sheet of kitchen paper where the seeds are on. Once the paper is in place, spray the paper again so that the wet paper towel makes good contact with the seeds. This is very important to let the pot seeds germinate well.

Step 4: Covering

To germinate the seeds, the seeds must be in a dark environment.

What to do?

You take the second plate and place it upside down on the plate with the seeds.

Note: because the seeds need oxygen to germinate, the edges of the plates may not lie exactly on top of each other. Then place the double plate with seeds for 24 hours in a dark room with a constant temperature of 21° to 25°. Check every 5 to 8 hours if the paper is not dehydrated, without removing the top layer. Spray the paper again if necessary. This is very important. When the seeds become too dry, they can die and never germinate.

Step 5: How long does it take for weed seeds to grow roots: Check after 24 hours

A germination process lasts on average between 24 – 48 hours. After 24 hours you can do your first check by carefully removing the top layer of kitchen paper. The germinated seeds with a root of 1 to 1.5 cm have to be planted directly.

Seeds that haven’t germinated after 24 hours will need extra time. Provide these seeds with another additional 24 hours and repeat step 5 by keeping the paper towel wet. Check again after 24 hours whether these seeds have germinated. In rare case, germination can take up to 168 hours.

Note: Be very careful when the seeds germinate. Avoid poking, pulling or touching the seeds with bare hands. You don’t want to damage the roots.
