KFFKFF 20ft by 10ft by 7ft Walk-through Tunnel Greenhouse, Movable Plant Warm House with Zinc-coated Steel Hoops, Trio of Upper Beams, Cross Poles, Dual Zippered Entrances & Dozen Roll-up Windows

I got it earlier than expected which was super! But I still haven't gotten the chance to assemble it. I will update this review after I build it. The galvanized steel tubing is rather thin but I got this one because it was the cheapest for its size and good structural support. The plastic for the cover is a mesh with clear plastic on it. Mine came with a tiny hole because the tubing ripped a small hole in it. I don't mind though since I plan to replace this with better official greenhouse plastic when it gives out and also replace the end walls by making polycarbonate walls with a door instead of a wimpy zipper. I will also say that the instructions are not very great but it is simple in design. I have done some research and from what I found I believe this will need added structural support. I wanted to find more tubing that could fit in the bottom of the arches. Then put them into the ground and bolt them onto the frame as they do professionally. I think I will settle with rebar bent into a u shape then secure the bottom of the frame into the ground for now since I have the rebar. I was hoping I could get this at a discount since I'm a Walmart employee but it didn't accept the discount so that was a shame.
