I have a small backyard. I bought this greenhouse for the couple of winter months we get in the Southwest. As it turns out, we got 6 inches of snow! These were the perfect size, so I bought 2. I had been shopping, and these were over $100. These are my "outdoor" walk in closets for my succulents and cacti (116 pots)  I didn't want permanent fixtures, so these will be easy to disassemble and store them for the summer months. 

Pros: Value! Value! Value!  
Cons: None.
