My husband and cousin built me a really nice greenhouse. No more buying $5 tomatoes at the grocery store. This thing is so well made, if a hurricane comes, we're hunker'n down inside the greenhouse. The plans can be seen at buildeazy.com. It's 8 by 10 and we used 6 concrete footers made using form tubes. We have since added four windows which we cut into the side using a 142 tooth Skillsaw blade and then covered with screen. We found it cuts polycarbonate the best. The polycarbonate sheets from a company called TufTex. We purchased ours at the local Lowe's. Changed music to video (12/18/2013) much better!
