So very disappointed in this greenhouse purchase. The metal is VERY thin. Bolts and plates are already rusting. Hasnt even been a month yet. Finished setting it up around Sept. 19, 2026 as we still had to finish prepping the area when it arrived. Wish I had sent it back before we even attempted to put it together. But we were hoping it would be sturdy once it was built. I bought it because it said heavy duty, price was good, had a 4+ review and wind rating was higher then most. We are retired, on a fixed income, so I try to be smart with big purchases. There's ALOT of room for improvement.. Lulu. FL. Mon Oct 05 2026

It turned out pretty nice for the price. We have a couple of spots that are damaged- one seam was apart and the Velcro strap came off when strapping around the bottom. I would suggest making sure you prep your land prior to assembling, which is what we did. Both doors are rollup and straps with clasps.. Sherah. Talladega, AL. Wed Feb 18 2026

We were able to build it fairly easily BUT we had a few parts that were not the correct size. We are waiting for the manufacturer to contact us regarding replacement of the 2 roof vents which were about 6inches too short. One of the corner frames was too short by about an inch as well. we were able to make this work by drilling a different hole but it was incredibly frustrating to deal with. I think we were unlucky enough to get a box that had been previously opened. Many of the parts were dented, though not beyond use, and it was not really obvious that they were until we started putting the poly panels into the frames. If the manufacturer makes this right, by replacing the vents, I would probably give it 4 stars. I am very excited to have it completed and it is quite sizable. My husband is 6ft1 and is able to walk around the majority of the space without ducking. I am 5ft4 and can stand at the shortest side without ducking. Update!! The manufacturer was super helpful and replaced our incorrect parts quickly. Edited review to 4 stars. Sarah. Waukesha, WI. Fri Jun 19 2026

Nice greenhouse. Sturdier than I expected. Directions aren’t the greatest but we got it together. I had an issue with a missing part and Wayfair’s customer service was phenomenal.
