I bought the Sturibuilt Tropic model greenhouse 10 x 14 feet. The workmanship on the pieces was good and it was a good working greenhouse. We grew flowers in it for about 10 years until it started to rot away. Every place there were iron fasteners installed by their factory the redwood rotted first. The door started sagging and eventually the whole roof line started to droop. The redwood was so completely disintegrated that it could not be repaired. It became an eyesore to the neighborhood and had to be replaced. The experience was very disappointing and Rick at Sturdibuilt was not helpful. This time we are going with aluminum so it will last more than just a few years.
