what you talking about. Big greenhouse grows use carbon filters even when the sides are up, pretty sure they use 10-12in units at 1 per 10sq metres or something like that. It’s not about removing all the smell just some of itI figure you guys aren’t looking at hanging a carbon filter/exhaust fan outside in the open?? Won’t be too effective if planning on doing that imo. You really need plants to be somewhere that’s fairly boxed in so the fan/filter can filter the air around plants....
