Because of my living area & space issues I've converted my setups into 3 DarkRoom 60II tents. Each w/ a 400 HPS / 6" blower exhaust & 2 x 6" intake. 2 plants a piece , all scrog grows. I keep them in the same room a few feet away from each other in a line. I've recently noticed that a light leak must be occurring through the duct fans ( since they are staggered, one on veg might be leaking into a night tent next to it. I thought I accounted for this w baffles but... I figure the best way to fix the problem would to be make three separate chambers out of the one w/ blk/wht plastic, creating light trap walls in between each unit. I o II o II o I Like so. The o's being tents and I 's the plastic walls Any thoughts about a better way?
