I bought one from Lowe's for 10$ it blew away once so now I have it very tied down to my porch. I also duct taped it together because it really wasn't sturdy. I have been keeping it open during the summer months because it's just too hot closed. So far it works wonderfully for seed starting. I have heat matts for the winter for it and I will probably be buying a little bit heavier plastic to cover it more in the winter months.
