Do you hook that up inline with exhaust? or just put into the area? I've heard that ozone can be detrimental but I'm sure if it's only small amounts it wouldn't be too bad. The vaportek optimum 4000 I heard about from rezdog. He grows a lot of sour diesel so I'm sure if they can handle his fairly large areas they would handle most setups. I think those are industrial use anyways lol.
