The Paper Towel Method For Cannabis Seed Germination

The paper towel method is the most commonly used technique to germinate cannabis seeds.After your seeds have been soaked, you will need to prepare some things before moving the seeds onto paper towels:

4-6 Paper Towels
2 x Plates or Saucers
Cling film/ Plastic wrap

Step 1: Wet a paper towel (or 2, depending on how thick the towels are), so it is wet, but not dripping with water, place this on top of one of your saucers.

Next, place your seeds, around the paper towel on top of the plate. Space them out evenly, and then cover them, with another paper towel.

Lightly wet the paper towel that covers the cannabis seeds, and then, turn your second saucer upside down, and place it over the top of the seeds like a dome.

Step 2: Paper Towels
Wrap the saucers in cling film, so that no moisture can easily escape. Now, you have to store it in a warm place, like your heated propagator, modem, or games console for 24 hours.

Check on the paper towels after 8 hours, just to ensure they have not dried out. If moisture is escaping, then the towel may dry out. This will cause your cannabis seed to dehydrate and die.

After 24-48 hours, you should see the cannabis seed is cracking, and a taproot is forming. This is a good time to plant your cannabis seed into the growing medium.
