Review on Gardman 7622 Walk-In Greenhouse: Superior Shelving, Size 75" L x 49" W x 75" H by Tony Jockheck

Not a large greenhouse, but good for holding my seedlings before they are ready for outdoor planting. I think if I were to leave it up all winter it may become damaged because the plastic isnt that thick and the poles aren't so sturdy. We have it placed in a well protected nook nestled between the house and the deck where it is protected from the wind somewhat. I don't think it would last long in high winds without any windbreak or protection. For our purpose, only using it a few months in the spring and winter for seedlings I think it should last several years at least.
