at least 18/6 vegging until they get about 12" - 18"

get some foxfarm ocean forest soil at any good grow store and some bloom food...organic preferrably...just as P-man said...start simple and don't over water. your temps can go pretty low as long as you don't freeze them literally you are ok but i personally like to keep mine 60+ in the dark!

looks good so far!:thumbsup:
