I love these green houses and they worked great with my raised garden beds.  I used them to get a jump on the growing season.  They worked well, I would open in the morning and close at night.  It keep the animals out and protected the plants from frost.  I had great success with my peppers and lettuce.  NOW THE ISSUES I would suggest staking them down as the wind will pick them up and blow across the yard, once I did that they stayed in place.  The other issue is one of the zippers broke the first month I had to tape that side closed and was not able to open during the day. Watering was a bit of challenge.
