I've been out of the market for several years now due to a mOve into town. But we recently purchased two acres dirt cheap hahaha. There is an old pole barn which has a decent roof structure but the tin is about shot. The sides are just old garage doors shower doors anything big and flat I'm stripping it down with the intent of converting it to a greenhouse. Gh plastic on the sides which are a little less than eight feet. I was thinking of using that clear corrugated from lowes for the roof. Any advice?
