Stinky, I mean for when I run co2. I don't wanna dump the gas every time the humidity gets above 50%. The controller I'm getting has seperate outlets so you can use a dehumidifier instead of dumping the gas. That way If I can keep the temps under 93 F or so (I have an air-cooled light) then I'll use less co2. See pics of my setup here..
