Was wanting to know if in the spring summer months ,Tennessee humidity,if i should be opening my vents for air circulation to crawlspace.
I had moisture issue under home,no ac operating either,and i do have the black plastic in crawlspace.sometimes small condensation on it before I dehumified it .
Some say close entire area off to keep outside humidity out ,another says let air circulate to prevent mold/fungus..and vapor escape.
Which would be best considering location,set up,etc?
 
I would leave them open. If you are the guy suggesting leaving them closed to stop humitity from getting in, would you then close all attic vents too, I don't think so.
