Vapor Barriers

[buddog]

Is there any problem with having two vapor barriers in your grow room?

I don't even have one, at least that I know of. Don't you hate that feeling you get when you find out you might be missing something important?

What is the reason for a vapor barrier?

 

[buddog]

Acts like insulation It is just dead air space

batted insulation will have the treated paper vapor barrier. that is all my room has for a vapor barrier. but then I also have the room drywalled and taped and bedded then painted I think in my shed it is not needed as the temps inside and out are kinda close. maybe 20degrees different
