My greenhouse has been up and in use (before the cold) and it really is a nice little addition. I’m sure next year I’ll love it.
Shipping was very slow. It finally arrived in manageable boxes. There are a LOT of components. It would have helped if the nuts and bolts were labeled as they are very similarly sized. I had 3 missing parts that I could improvise through. The instructions are all visual, not much written, making it tough to follow. Assembly is a bear!! I cursed a lot and it took a while. Get extra help. Make absolutely certain it is squared up. Components will not fit together if it’s not squared.
I purchased two vent windows that again were difficult to fit properly but they work quite well.
During assembly with all my cursing I said “I’d better love this thing forever after all this” and fortunately I think I will. It has been sturdy through strong wind, heavy rain, and now snow.
