I'm considering a 2 tent, closed loop system to better control temp, humidity and maintain a good CO2 level. My current system takes in fresh air and exhausts outside. The cooling and dehumidification I do goes right out the proverbial window. The exhaust fans will pretty much act as scrubbers but with a good carbon filter (looking at the Can 24" units) should keep the smell down. Does anyone have any experience with this type of application? Looking for advice
