hey guys, ive seen post/blogs etc.. about cfl lights everyone uses them, but im new and i was wondering if any kind of cfl light would work, does it have to be a certain colour? i have a 20w cfl that has a yellowish colour, sun-like. Then i have a 32w CFL which is cooler white ice like colour, can anytype of CFL be used or must it a certain colour. right now for my sprout im using the 20w yellow coloured bulb and also placing the sprout outdoors in the side during the day, all ideas are welcomed thanks.
