I am very happy with the Greenhouse so far. It has withstood 45 mph winds with no problem. I had to have some help with a concrete block base as well as assembling it. The drawings are difficult to understand. I did put down a bead of silicon sealant on each panel to help ensure they stay in place in a high wind. I ordered the tie down kit and the automatic louver opener and both are a good idea. I inadvertently damaged one of the gutter downspouts and tried to order a replacement direct from Palram. Impossible. So I tried Wayfair and they got back promptly having tried to no avail to order them for me. Seems Palram does not sell replacement parts! How can that be?
