400w in that space will be fine

Home depot has soil that is for seedlings, Scotts makes it I think. They also have a soil high in "P" that gets roots going.

Or just by good soil for around $3.00+ a bag

HD has soil by "Earthgrow" Do not by that cheap shit.
ProjectEight Reviewed by ProjectEight on . few questions on the stages of growth I've watched videos and documents and taken notes but I still have a few questions on the stages of growth 1) Germination and seedling - between moist paper towels and when a sprout cracks up you put it in 3/4 inches deep into those egg carton looking thingies. keep the soil moist and the hps light 2 feet away when a seedling pops up...my q is should i use fertilizer? and when do i transplant these seedlings into the 4 gallon pot? 2) vegetative - feed fertilizer and water frequently.
