co2 can not be used during the dark .It does no good you have to have HID lights for it to work, no floruo's. You can exhaust all you want in the dark. The only way to cut down on smell is to be air tight and an air lock entry door system. I want to go co2 but the money is holding me back right now. I'm just finishing up a small flower room and the ehaust is not what I want but will live with it for now.
LOC NAR1958 Reviewed by LOC NAR1958 on . How can I use co2 without causing odor? Hereâ??s the problem: youâ??re running co2. So your exhaust is turned off for long periods of time. Youâ??re flowering. Obviously, with no exhaust the odor will quickly fill your house and next be smellable from outside. Iâ??ve heard ozone generators are harmful to plants (and humans) so canâ??t have one in the growroom to stop odor at the sourceâ?¦â?¦â?¦â?¦â?¦ Do people that run co2 just allow their house to reek?? Controllers turn the fans on periodically â?? but donâ??t do anything Rating: 5
