I had a thread in soil grows when I did this wee crop but I thought I might throw one in Micro grows since there is alot of cfl threads in here. I did this box up for about $150. had about 300W of flouros in her (added a couple more towards the end to get at some dark spots) and kept them as close to the plants and specifically the main bud sites as possible. Moved them alot but it was well worth it. I went in somewhat skeptical as it was my first time flowering under cfls but I was pleasantly surprised.
