How to germinate cannabis seeds: Tried and tested method
At Cannabist we have tested just about every method to germinate cannabis seeds and always get the best results with the cotton pad method. There are a few critical things you need to pay attention to when using this method, other than that the method it is pretty straight forward.
Use make-up pads, nothing else
Don’t use roller/paper towel, tissues or toilet paper, only use make-up cotton pad as they retain the right level of moisture and allow air in to reach the roots.
Don’t use too much water, or your seeds will drown!
Each pad only needs 3-5 quick sprays from a misting bottle to moisten them. Cannabis seeds need both moisture and air. If the pads are too wet, the roots will be submerged in water when they sprout and won’t be able to breath. As a result they will rot and die! A brown colour on the tip of the root is a telltale sign that there is too much water.
Keep the moisture locked in, or your seeds will dry up and die!
If you wet the cotton pads and leave them out and exposed, the cannabis seeds will dry out and die! Place the cotton pads with the seeds in sealable container or on a plate wrapped in cling film / cling wrap to lock the moisture in.
Seeds germinate better when warm
Cannabis seeds have the highest germination success rate right around the sweet spot of 26°C. They can still germinate at other temperatures, although successful germination drastically declines below 21°C and above 30°C. What we at Cannabist find works best, is to pop the sealed container or covered plate containing the seeds on top of a fridge, near the back, which gives off a bit of heat which keeps the seeds nice and warm.
The less you fiddle, the better. Most seeds should germinate in 2-3 days but can take up to 10 days (or more). Sometimes the seed’s shell can be quite hard and water struggles to penetrate the shell. If your seeds haven’t germinated after 10 days, you can place them in a shot glass of water for 24 hours and then attempt the cotton pad method again.
