My buddy has 2 extra lights sitting around that he can add to his current grow; a 400mh and a 1000mh. He currently has two 600w HPS lights in the flower room. Since he wants to reduce power, I suggested putting the 600's on a schedule of 11hrs each (offset so one starts first, one finishes) and the middle 400mh being 11hrs also (middle of light schedule). He believes that plants can't absorb more than 6hrs of blue light in flowering though, so it's pointless. His idea uses about the same power, but with a lot more blue light and a little less red: Left side 600HPS --- 12am-10am (10hrs) Middle 1000MH --- 3am - 9am (6hrs) Right 600HPS --- 2am - 12pm (10hrs) The lights are set up from East to West, with the blue light being in the middle and all lights pretty close because it's only covering 2 plants deep by 5 plants long (10 total). He's medical so can't do anymore than 15 total and usually has a few in veg to be perpetual. Veg room just has a 250mh to reduce power. Which method is better? Does it even matter at this point?
