Hi we built a greenhouse in the summer, the base didn't set quite level so its a few mm lower one end. It seems sturdy enough and survived the storm we just had ok. I guess the slope helps the run off into the water butt. Its pretty solid. Can't do much about it now but I think it should be ok and last several years? Do any of you guys have your greenhouses sloped slightly? I think its just my ocd haha. Another thing is it best to put some kind of sealant around the polycarbonate?
Thanks đ
