I love the greenhouse, we have the same type in our garden ended up taking out a few poles and shortening it. We added big concretes blocks in the bottom to keep it from getting torn down in storms. Since then it's survived better than neighbours expensive glass ones in winter. Hope yours stands up well through winter too.
