one more thing on your lights, 24/7 is good under flouros but not good under HID, there is much controversy to 24/7-18/6 which is better, but in one of the latest issues of maximum yeild theres an article on what your plants do at night, alot of the clorophyll produced during the day is used at night, as well as cell development and repair, if you get a chance to pick it up its a wealth of information, i personally run my sprouts for a week under 24/7 flouros then switch to MH at 18/6
