exhaust fan while drying

I have a question, If I am drying in my grow room. Do I want to keep the room sealed. Or would I keep my exhaust fan running a bit with the intake fan? or is it best just to seal it up.

I like some air exchange as long as there isn't a fan blowing right on the flowers

Fresh air is your friend, just keep it dark. What's your temp and humidity in your grow room?
