VEVOR Walk-in Tunnel Greenhouse, Portable Plant Hot House w/ Galvanized Steel Hoops, 3 Top Beams, Diagonal Poles, 2 Zippered Doors & 12 Roll-up Windows, Green, 20'x10'x7'

take some 4x4 posts and lay them out and then build this on top of the 4x4's and then screw this down to those and use 2x4 scrap to fasten the 4x4 together and you have a very sturdy wind/stormproof beast. i also went ahead and used 2 10 foot 2x6 and 2 4x4 to make a header. i post holed the 4x4 a bit into the ground and then held up the 2x6's and bolted the to the 4x4 down the middle. i made sure the 2x6 was touching the bottom inside of every loop and now it can take some serious weight. i went a bit further and built out 2x4 doors on each end and i stapled the fabric on the outside of the zipper to the 2x4 frame and then screwed some 1x2 to sandwich the fabric. this thing now will last years of some pretty serious storms and can take a lot of weight from rain/snow. you could hang off it now.

Do NOT buy this product. Arrived in terrible shape, no instruction manual, and missing parts. It is not powder coated as described either. We did not open it completely even though it was in terrible condition as it was winter. After opening it a couple of weeks ago and finding the problems, we were instructed by Amazon to contact Vevor directly. After having to google and find Vevor, we had to send an email. Found out Vevor is on China. Received a response that said we had to send a photograph and the exact pieces missing. After telling them we have no idea what pieces were missing, we got no better response. Sadly then found out it was past the return date for Amazon to return it. BIG rip-off. Disappointed in Amazon. Will not be ordering items from them again.

I bought one,, put it together,, and then it got windy,, where I live we get 30+ mile an hour winds twice a month,, the wind kicked its butt,, the next day I got some screws and washers, and I drilled holes in the frame and screw washers to hold it in place,, that turned out to be a really good idea,, then I zip tied the bottom of the tarp to the frame so the whole thing is basically attached to the frame and now it takes the wind a lot better,, other than that,, love the thing,, we’re having a lot of fun with it

The price was great as a beginner set up. My wife wanted it taller so I set landscape timbers as post and built a 24" tall foundation. It took me a day to assemble. I just used 1/2" 2hole pipe straps to anchor to the wood frame. Installed landscape fabric for the floor threw in some wire rack shelves works like a dream for my seed starting and bonsai trees.

Was a cool green house. Assembly took about an hour by myself. Plenty of room on the inside. Collapsed in the first mild thunderstorm and bent many poles

Materials could have been little stronger. Blew over in storm. But for price it served the purpose for the most part.

The build quality was perfectly fine. The manual recommended the frame be buried: check. Tie downs used: check. Greenhouse covering weighted down: check. 3 days after set up, I come home to this (pictures). The tunnel section is completely ripped away from one of the door panels. For extra clarification, my area has only had sporadic wind gusts up to 15mph.

I purchased this greenhouse in the spring and it is now midsummer. I will explain modifications I made and how it is going so far. I had a family friend clear and level and spot with a tractor before we setup the greenhouse. I am 5'4 and I was able to mostly assemble the frame by myself and had family help me install the canvas. We used the stakes included and put the bottom flaps in a trench per the instructions. For additional support we added 3 large ratchet straps across the roof to keep it from blowing away and lined all of the sides with cement blocks. After some heavy winds about a week after setup the bottom flaps came out of the blocks and dirt. We had to add more dirt and rocks to help hold it down. After this incident we have not had any other issues with the wind so far. However a few small holes have occurred in areas of the canvas and one of the zippers broke after a couple of weeks of use and I had to put a keyring on it to open and close it. We run a solar fan and a small box fan inside during the hot summer days. So far, we have grown tomatoes, cucumbers, lettuce, squash, watermelons and a couple of potted blueberry bushes inside of the greenhouse. I hope it will continue to hold up for further seasons.
