Im deciding whether to run two rooms on a flip flop schedule, or to just make it one big room and run the lights in an alternating checker pattern. I cant run all lights at once. Im trying to get input from people who have experience with this checker pattern style. Im looking for info on how much it effects both yield/quality. Also looking for info as to what how often you should alternate your lights. I think i remember reading a mag article that said to do it every 2 hours but i would like some more first hand knowledge. Thx in advance. -s'h
