This feels like one of those things that needs a long term update in another 6 months. What size fan do you have feeding it? And is the fan pushing or pulling air through the filter?
My wife gives me those side glances, especially when it gets to harvest time, so I’m interested. Especially since I like to allow my exhaust fan to turn off now & again to prevent environment controls from needing to work harder to keep up with what’s being exhausted.
I already run a round filter on my tent exhaust fan input & another filter on the output, but even with that there’s some odor as the plants mature. I keep looking for possible solutions to exhaust outside…but aside from running a second dryer-style outlet from the basement, I haven’t come up with anything yet.
