nice nice nice. your setup is very similar to mine. i do (2) 4x4 tents, both with 600 watts, flip flopped. air circulates from room to room via cooltubes. my intakes are on a timer so when the light is off in room a, the intake is on, so in tent b the inake is off whem light is on, and vice-versa. wanna go to propane burner soon.
