I have had no luck with cfl's, It wasent until i purchased an HID that i got anything good to grow. go to a local hardware store and get a HPS floodlight, i've heard of people having good results with them. Or look in the phone book, or on websites for addresses of hydroponic stores near you, they tend to post up in places you would have never thought of looking, I think they get cheaper leasing that way, or something.
