In 60 minutes of minor disagreements my wife and I had the greenhouse assembled, tied down, staked down (stakes from Harbor Freight), windows rolled up, and plants inside protected from hungry birds and rabbits. Two NM windy monsoons have not been able to move or damage the unit in any way. And best of all is your price was $40 less than Lowe¡¯s.
Overall, I feel this is a good purchase though I do have some regrets after putting it up because I live in South Florida and due to hurricanes. My own fault of course but I did not realize the entire thing was as light as it was. So I used the provided ropes to tie it down and put a ton of rocks and weights on all around the base. The problem is that the ropes all broke within two weeks. I don't just mean break, I mean disintegrate. I have never seen such cheap ropes before. I went to untie the first broken rope after one week and the knot just fell off as soon as I touched it. I didn't even untie it yet before it just came off in pieces. Also, the stakes are not going to work either so you will have to invest in quality stakes. So if you buy this, buy your own rope/twine to tie it down. Other than that, it is working just fine and I love how big it is.
My greenhouse came so quickly, was reasonably easy to put together. it works well, had the inside warmed up instantly. instructions were easy to follow, and everything was labelled. Followed the extra suggestion to secure it for wind, have plants growing inside it already.
Quick delivery, Went up easy as directed. Only problem is that the 4 stakes & ties are not sufficient to hold down in wind. We have weighted down with breaks for now & will later add pressure treated wood & conduit clamps. We get some pretty high winds here in Montana but for the price I am very happy. Hope to extend my garden season longer! I should have bought 2 since this only covered half of my garden area, definitely recommend.
Bought this in hopes of using it all seasons, it would have been helpful if all the holes had been drilled, this in turn made it not totally square, the cover certainly cannot stand up to wind it busted open at the seams at 2 corners so I have had to duct tape the seams, no idea how long that will last. If I could replace the cover I would.
