From what I know about growing, DONT MESS WITH THE LIGHTING! I've never had nothing but bad luck messing with the lighting, it made my first indoor plant stop growing all together. it was still alive, but grew no more, when i flowered it, it took twice as long as it should have, and the weed sucked! i re-veged the same plant, and it did alot better the second time around, but i learned if you start with one light, switch it off, and switch it again and again, your gonna be pissed at the results.
