Very good started greenhouse for me. I am very pleased. I live in zone 9 so we don't get cold very often but it held up with gust of wind and kept my babies nice and warm. I definitely recommend. I also recommend digging around the area and preparing a place for this greenhouse. It explain it in the instructions. I wish the instructions were a little more details but with my husband's help I was able to out it up fairly quickly and I couldn't be happier
