Damn. I must be overkilling it again. I have an intake to my tent, bringing fresh air from an adjoining room (6" flexi-duct hooked to 8" inline fan), 2-6" clip on oscillating fans, an 8" fan for my carbon filter and a 6" inline fan exhausting warm air from grow room into my basement stairwell and they all run 24/7 ---

24/7 and I have 3 fans in my 3x3, a small one on my drying tent and a one in my 2x2. Exhaust fans are 24/7 also or the dankness escapes and fills the hood with the pleasant smell of cannabis. ---

+1 for 24/7. Helps manage CO2, temps, humidity, a good breeze across your plants builds strong stalks/stems, and good air circulation mitigates mold and the like. I try to have the air in my tent replaced at least once per minute.
