VEVOR Walk-in Green House, 4.6 x 2.4 x 6.7 ft, Greenhouse with Shelves, High Strength PE Cover with Doors, Windows and Steel Frame, Set Up in Minutes, for Planting and Storage

No

Yes

Not really

I had it anchored well, it withstood some very high spring wind storms, I’ll use it again this coming spring it’s still in great shape

I have found that the shelves are a little flimsy. They cannot holdore than 10lbs

Well I wouldn’t waste money on it. I would get something a little more sturdy. Small . Wind blows it’s Gone.

Not sure what exactly you are asking. If is about withstanding strong winds...you will need to anchor the greenhouse or it will tip over/blow over.

This greenhouse is perfect for unpredictable spring weather, starting seedlings or holding young plants until no cold nighttime temperatures. I don't think it will work for your cold winter temperatures. There is no heater and no ventilation other than opening the door.

I really don't know. We purchased this in the Spring and have not been thru a winter yet. Additionally, we are located in Louisiana, not quite as cold as your area.

no...I only use the greenhouse when the temps are down to the 20's. I move the plants inside when lower than that.

Not with out a heat source to maintain a minimum of 55degrees F
