I have a regulator at 1500ppm my issue is I'm hitting high 80s low 90s!! I'm thinking alot of it is in use of the halide bulb I'm considering switching in my hps but in the mean time I turned off the co2 and put down my decided to slow basement air to flow freely like I had before my issue is as soon as things are rolling that's not an option as A: I need two rooms, and B: I HAVE TO KEEP ODOR IN!!! so... I'm trying to work the kinks out of my set up while I can before its too late ya know!?
