1 ft when done or 1 ft when put into flower from veg? i'd get some y-splitters and get more lower wattage cfls, i'd get a 4 pack(at least, more is always better as long as you can control the heat) of 26w 2700k(about, it doesnt have to be 26w, a 23w or 32w pack will do fine if you cant find any, its just they are the most effecient usually in their watt to lumen ratio) and 2 blue spectrum 6500k 26w (around 26w, like i said b4, lol) how big is your grow area?
