I hung my fluorescent lamps from above, kept them 1" -2" above the plants ... I still use an additional four tubes in flowering, I screwed them to the rear wall about 2' above the floor ... that gives my plants 400-watt HPS above, and 160 watts of fluorescent light, along the back wall, to light up my lower branches (only two in this older photo) ... I give the pots a 1/4 turn every coupla days ... :smokin:
