Make a hole in the growing medium that is about twice as deep as the seed is long, so that each germinated cannabis seed sits 2-5mm below the surface.
The best way to germinate cannabis seeds requires only two saucers or plates and some moist tissue. Here is a step by step guide.
Lastly, cover everything with the second plate, upside down, to form a ‘clam-shell’ shape – this will create the dark, moist environment necessary for germination.
Step 3. Potting – How to germinate cannabis seeds
Seedlings intended for outdoors should be acclimatised to direct sunlight by placing them on a windowsill inside the house and increasing their exposure to direct sunlight by an hour or two per day.
Place another few layers of moist tissue on top of the seeds, again allowing excess water to drain off.
Line the bottom of the first plate with a few layers of wet tissue and drain any excess water from the plate.
Cannabis seedlings usually emerge from the growing medium 24 to 72 hours after the germinated seeds are planted.
So, Rockwool or peat? The primary difference comes down to how you will grow the plant after germination.
After examining each method, if you absolutely had to pick one, it would be starter cubes and seedling plugs.
How To Germinate With Plugs:
Rockwool cubes, composed of fibrous wool-like material provide great water and air exchange, which is ideal in hydroponics.
Next, transition them to either soil or plugs.
Step 1: Place your seeds in a container of clean water and allow to soak overnight, or for at least 12 hours.
