So if I germ my seeds in a paper towel and put then in soil after they pop and a plastic bag with holes over the cup how close should I put my 120 watt led from them and how long before they sprout?
You dont need the light on untill they sprout .. anywarw between a day and 3 is average for them to pop soil. When they do they arent going to need all that light ao if you have anyrhing smaller you can ise that till there a bit better established.
