Do not buy this greenhouse is you're area gets even wild wind. A few of my panels blew off at 40km/hr winds. Now we got 80km/hr winds (greenhouse is rated for 90) and my greenhouse is gone. Spend a bunch of money and time setting it up. I went above and beyond their installation recommendations even cementing the base into the ground and cross bracing all of the panels. The material all the structural components are made of are very thin.
