Hello I was posting wondering if an Window Ac unit brings fresh air for plants & is it healthy for them? I know its dehumidified air & I plan on making up the difference if any with a Humidifier/Dehumidifier.
Ac units only recirculate air in the room, they don't bring in fresh air. And don't count on it hehumidifying if the rh is high, you may need a separate dehumidifier.
You still need a fresh air source. The negative pressure of the tent keeps the parasites out and keeps the odor from escaping. If you have sealed hoods, you can draw and vent directly to the outside without worrying about odor.
