thas is a perfect chart.....that is asssuming its accurate, which it looks like it is. that being read, 10 or 12 inches away really has NOT that much difference for phto...which is the goal....its still 100% diff or whatever but if ten inches is too hot, go to 12, or 11......
very good question. that chart is sweet. hope its right.......600w vented, sealed is the ay to go..
give it more vent, get more light!!!
easier said than done.....
whats the temp running in there?
