Sealed-ish room exhaust.

[Valeris]

I have a room that isn't purposely a sealed room, but I've sealed off the air return and the gaps in the door etc and maybe a small amount of air could come from the vent in the ceiling that's closed but not sealed like the air return (needed to stop scent travel). What happens if I run the exhaust outside as normal? Where does the air that's being exhausted come from and would it be problematic?

Edit: note I'm running an I inch ac infinity I keep at a minimum of 4 and a max of 7 on a high temp trigger.

You will create a negative pressure in the room which is bad. You need some sort of intake or your gonna cut the life of your exhaust fan by half at least.

Sealed grows don't have exhausts. If you want to refresh the air you gotta use high grade HEPA filtration, Carbon Scrubbers (Ideal for removing VOCs), Air Conditioning (Heating/Cooling), Dehumidifier(s) and Co2 Supplementation to treat the air. Plants put off oxygen when lights are off so that naturally replenishes the o2 in the rooms, HEPA filters, dehumidifiers and air conditioners will keep your environment in check. I would strongly avoid intakes or exhausts as its just inviting pests & disease.

Don't ACs pull warm air out of a room to replace it with cooler air? How do you do this without exhaust and intake?
