There are certainly many different ways of germinating a seed. Personally I have never used the glass of water method. Most of the time I plant directly into soil if I'm using soil. If I'm using cocoa I use the paper towel method. Knock on wood, so far I have a 100% germination rate. If you are using soil my best recommendation is to use red solo cups poke a bunch of holes in the bottom. Fill the cup with whatever medium you're using and completely saturate it with properly ph'ed water say 6.5 ph. Let all of the water completely drain out then poke a hole in the soil in the middle of the cup to the first knuckle of your index finger. Drop the seed in and cover it loosely. Yes, the seeds should be in the dark and the soil should be around 80 degrees. A seed heating blanket is great. Once the seeds poke though the soil then you can use your light. As for the paper towel method I would let your seeds get to room temp then put them in the wet paper towel method, Keep it moist dark and warm. Once they pop very carefully remove from the towel being careful that the tap root hasn't attached to the fiber of the towel and then transplant into solo cup using the same method. Tap root down.
Thank you mate for your reply !
Well , i have 5 seeds left in the paper towel ( closed dark place under my bulbs ) , I will wait 1-2 days and then i will put them in soil whatever their condition (even if they haven't show root)
Peace !
