Should I block AC vent in grow room

From a fellow grower: I have an empty room in my house and plan to use grow tents, I guess. My one question is should I block the ac vent in that room? Thanks

Ac good heat bad


Why are you thinking of blocking the vent?
Temperature? Smell? Humidity?
I just adjust my vent to keep the temps where I want them.

Agree, except when its 20 degrees outside. :cold_face:

I wouldn’t block the vent.

My thoughts say the room is 70 degrees in the house tent set up in room with lights on 78 to 80 degrees. Exhausting hot stale air outside. Pulling fresh air in out of room at 70 degrees should be a pretty good balance I would not shut vent, just my thoughts good luck.
