I plan to grow 12 plants in ebb and grow system in a 8 by 8 by 8 tent. I will move them in next week under 2 400 MH lights for veg. Im wondering what would be best way to light during flower. Obviously Im trying to maximize yield. I have the lights on an adjustable system, so can put any distance away from plants. Im considering 600 or 1000 hps. I have seen the chart for optimal distance but I wonder should I put 2 1000 watt in there or 3 600 watt, or some other combination for optimum grow? Looking at the chart it seems 600's at closer distance is better/cheaper, but something must be wrong there or nobody would ever use 1000's. Must have something to do with coverage area I guess.
Thanks
