Do window ac's pull odor out or just recirculate the same air. My big window ac in living room has a lever on it that says exhaust, when I use it the ac is still cooling but also exhausting and bringing in fresh air from the outside. My little bedroom size ac does not have that feature just ac high or low or fan only, so i'm not sure if it will exhaust the odor and bring in fresh air ??? The living room ac cost over $500 i'm not going to spend that much on my little grow box LOL. Will my smaller window ac exhaust and bring in fresh air while cooling and exhaust and bring in fresh air while just running the fan and not ac for cooling. If this extra little ac I have in basement would work as I described it would solve my problem all the way around as I have one that I'm not using. No more $$$ spent.I'd suck the air out of the grow box, keeping it under vacume. If you pressurize it more odor will escape. I'd definately throw a small A/C unit in the window. Then you'll be able to contain the air and odor in the room. You can then control the temp & RH in the room subsequently controlling the atmosphere in the grow space. Good luck!
