greenAFanswered grow question 23d ago Not to mention if ur grow space isn't completely sealed and is in your home/occupied space ozone is a no no. It will also degrade any activated carbon if there is any recirculation. Maybe would work if it was carbon ozone directly sent outdoors. Also if your fan is moving more air that the 03 can handle it will just push past it and defeat the purpose. It's also not good for plants, I would uninstall it immediately if your venting into an occupied space but that's just me. Get a bigger or more carbon filter would be my move, but to ea their own.
