I should mention the most important item you will definitely need. A shade cloth. Go to a site like greenhousemegastore.com. Look for a 12 x 12 45% black shade cloth with grommets. You can see mine in the photo. Without a shade cloth your greenhouse will seriously overhead on a sunny day in early spring, summer and early fall. It is an essential item. Good luck.
