Outsunny is here to help you extend your growing season. This lean-to greenhouse offers you the support of leaning against your own house. Featuring four zipper mesh windows, you can use to ventilate out excess humidity or check the progress of your plants. Use the two zipper doors that make up the side to walk in or seal shut your growing space. Made with outdoor in mind, the PE cover blocks UV to stop plants from receiving sun damage, and the strong galvanized steel frame resists water.
