I think I'm jealous ha ha .Thanks for the advice, but what about natural light, like in a greenhouse window to start? My other houseplants really love it. and now to really show my ignorance, what does cfls stand for? I don't mind spending the money, but I need to know what to get w/o having to ask the friendly staff at home depot "Gee, I'm growing some pot and neeed to know what are the best lights to do so?" Thanks
