oh, I see, well, i kind of agree with the guy who starts under cfls, but i only do it the first 3-5 (maybe 7 days if they arent doing as well as i'd like) till they get semi-established and then put under the hid lighting. ive got a air cooled hood so i start the hid 12-16 inches till they start taking off then bring it down to 4-6 inches. if you can do the same w/o it frying them i'd reccomend you do the same.
