Pretty good greenhouse for the price. Im 56 and I do have to duck when I enter and walk around but its not too bad. We anchored it to the concrete slab its on because it was trying to run off everytime it got windy. It only took me a few hours to put together by myself but for the roof panels I do recommend having a second person to help. We added a solar panel with a fan to give it circulation and my husband also rigged up some actuators to open the vent panels when it gets too hot. I have some very happy bell pepper plants now.
