If heat is not an issue why would you vent a good carbon scrubber outside the grow room ? I thought the whole point of filtering the air with carbon is to remove odors , so once the air passes through why not keep it circulating though the room ?
Would be easier as well , or am I missing something ?
Thanks for the reply , but fresh air can be brought in through a fresh air vent . I guess I am wondering why risk people noticing/hearing a large exhaust fan running an exterior vent ? Fresh air intake isn't a problem it can be passive, but an exhaust fan is noisy and leaves a heat print .
Is the average efficiency of a scrubber not that good at completely cleaning the air of ALL the odors ? So most just dump what remains outdoors for everyone to smell instead ? I can walk/drive around the city I live in and can smell where some of the grow OP's are because of the air dumping outside .

Because even though fresh air is coming in, you need to move the stale air out. Cannabis likes to have the entire volume of the grow area exchanged about twice a minute.
