I bought this little portable Greenhouse and I couldn't be happier with it. It has 21 square feet of growing space that is full of young plants.  It went together easily and the vinyl covering was absolutely no  problem to put on.  It is not going to withstand really gusty winds but we had gusts up to 15 mph, and it did just fine. But it's next to our house.  I'm happy with it, and since it is only a temporary structure, I will be probably putting it away soon until next fall when I plant cold weather veges.
