This is a great greenhouse so far. It came quicker than expected. I built a platform for it to help keep it level. My two young boys and I put it together easily in about 90 minutes. It was missing two connecters so I bought some PVC pipe alternates for the time being. I also had an extra shelf and no cable ties.

Had a little trouble fitting the cover flush, but Im sure after a day or so in the sun and loosening up from being rolled up for shipping, it will fit fine. I did use cable ties to secure the shelves and used cable staples to secure it to the platform. Having a tall person will help with getting the cover on. Otherwise, its easily a one person project. 

 I love the windows! I hope to use it for my winter plantings.
