I've had a couple of those stand up greenhouses and they can work great but there's tricks to it. Once you set it up, put heavy stuff on the bottom shelf to stabilize and weigh it down, or it can get blowed over in the wind. As long as your temps are halfway decent (atleast 40 or more), unzip the plastic cover for air circulation. and to keep temps inside down a bit from frying your starts.....but that also depends on how hot your area is when using it too.
And one of the worst things about them is that plastic cover. It can get kinda brittle and break or tear easily if you leave it out exposed to weather all year long. Then of course those zippers get stuck and/or break as well.
I had mine set up right against the house on the east facing side, so I figured it should have had plenty of protection from extremes, but there was still all those challenges. It did help protect seed starts and give them a little boost to the growing season, maybe by a couple of weeks so that is some help. Maybe they would have lasted longer & better, if that's all I had used it for and had then taken it down & put away. Which to me and my way of thinking, a greenhouse should be usable almost year round.
