I put the greenhouse together. A lot of the steps putting it together had you put stuff together and then in next step you had to take bolts loose. The biggest thing I don’t like is there are not any hinges for the vent! If the wind blows the vent falls down. As you can see in the pictures I anchored mine down with post in the corners and put rubber mats in the bottom of the greenhouse. The metal along the bottom of the greenhouse is too lightly made. It is sturdier after you put the metal frame under the bottom of it.
