Charlie – Very sorry to hear about your loss of the greenhouse. How fast were the gusts and was it in the open ? What a terrible shame, and all the work you put into it. JUST finished my 10×12 and must have spent over 150 hours building (and rebuilding) it. I’d heard about panel blow outs and have run a steel cable through most of the beams to at least keep them from getting away. I’d be interested in at least some of your panels as I’d like to build a vestibule / reinforcement between the GH and garage, and would like to have some replacements handy. Thanks.

Wow! – How strong were the winds and where do you live? I built my greenhouse with the north end attached to a garage, the east side blocked with large arbor vitae tress and the west side block by my house. We’ve had 60+ mph gusts and no problems.

WE lost our 10×12 greenhouse with the last strong winds. I happened to be home and was watching it, but my last trip out to see if it was ok turned out to be the last time I saw it. It collapsed in the wind. I was abble to save 90+ percent of the panels but the metal frame work is a total loss. Would anyone like to purchase the plastic sheets?

I wouldn’t say nothing but trouble…you must consider the price and remember that any item sold at HF, is not the top of the line quality. I will agree that the panels can be a pain, but I’ve screwed them down with on center screw & nylon washer backed by a rubber o-ring and this greenhouse has withstood some very nasty wind storms. I live near DePere Wisconsin and there is a polycarbonate distributor here who sells a 6mm UV protected panel. I had set up a preliminary site at uvpoly.com but have received no inquiries.
Bottom line is that the aluminum frame is nearly indestructible and the 4mm panels could be replaced quite easily with the 6mm variety.

Oh, and about the made in China statement – I’ve got news: EVERYTHING is now made in China!

I have two of these greenhouses. They are two years old and have been nothing but trouble. If you expect to keep the panels in, you will have to screw them down. There are some good web sites out there that tell you how to do that. Also, be aware that the Harbor Freight panels deteriorate very quickly. My roof panels are brittle and yellowing. I doubt if they have any UV protection at all. The panels are being advertised as being nearly indestructible. That is totally untrue. From what I hear, Harbor Freight is not standing behind the product. I don\\\’t know this for a fact because I haven\\\’t contacted them myself. If you replace panels, be sure to get good quality with a guaranteed life expectancy. I will have to replace many of my roof panels and will not be buying them from Harbor Freight. Everything they have is from China and there seems to be no quality control.

I too have this greenhouse and have had problems with the clip system. I now need to replace some of these panels. They have been damaged by blowing out. Where do you get these and how much are they?
