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
