Greenhouse itself is a little flimsy. The supports bend easily. The tie down pieces are mostly attached incorrectly, so you can only attach a few of them to hold the cover on. I have placed large stepping stones on the frame to give it some stability. Well see how it does in the wind.
Wind arrived today, and despite putting the greenhouse in a fairly sheltered location, the wind broke several connectors, and the frame bent significantly. Were going to try to salvage it by inserting dowels in the larger pieces of the frame. Were also going to glue it together and add gorilla tape to the broken connectors. Fingers crossed that it wasnt a waste of money!
