I was pleasantly surprised by this greenhouse. Some of the reviews were so so, especially saying they had to watch a video to put it up. We had it ready to go in about 20 minutes. I have 4 large plants, we bunched them together and lifted the "igloo" over them. We put leaves on the inside around the edges to form a seal and they love it! It is warm and humid inside even when cold outside. Caveat: I live in Texas, so far it's only gotten as low as 28 degrees.
