Nice, small and simple greenhouse. Don't expect it to stay put unless you do some extra modifying. We were slightly over estimating the toughness of the greenhouse. Metal pipes-nice! Bolts and nuts along with ties downs-nice! Ours was protected some from the Mi. elements, when we placed it behind a sturdy building. Then a heavy snow came and we did not get to clean if off fast enough and the roof poles failed. The company was on the spot with quick action to help out! Here is what could be done to help it out though. Use lock washers on all the 1/4-20 bolts. They just rattle off as the wind shakes it and poles come loose. Better tie downs are also key, better rope and stakes are a must. Inside could use a couple center poles for stability if you live in a snow biome. We also attached 2x4's along the bottom with screws to keep the flapping plastic from fraying away. It is like trying to tie a kite down and keep it from getting damaged. Directions need more love. Just take your time and breathe...... The more you secure, the longer it will last!
