All 3 seeds germinated within 24h in the damp paper towel (this method ALWAYS seems to work for me). I planted all of them in roughly 20L of coco coir each.
I decided to not give them any nutrients yet until the vegetative stage starts. Not having much experience yet, I have no idea if that beneficial or not.
Once the seeds were placed in the pots, I activated the FC4000 grow light from Mars Hydro to 25% light intensity, at approximately 30cm height from the top of the coco coir.
