DO NOT BUY THIS!!!  Looks pretty, easy to set up, roomy... but Damages EASILY in winds over 15mph!  I lost over $100 worth of plants in this thing today, we had about 20-25 mph winds and some rain, and the greenhouse was secured by its straps to 5 concrete blocks but it still went bye bye.  Ripped the fabric right where the straps are attached to it, left those on the concrete blocks, and flew away.  Twisted the frame like a pretzel and dumped all plants in the process :(  Had to request a refund.  Very very unhappy and won't buy this type again.  I DO NOT RECOMMEND THIS!
