I LOVE this greenhouse!!
We've had it for 2 months and one evening when it wasn't supposed to rain, I left one end open with all windows open. The next morning, popup storm!! Shredded the cover in multiple places, frame still looks great. I'm guessing the wind kept picking up the cover and slamming it back down on to the frame. Only the end that was still zipped got the most damage.
We did not bury the edges. We have the frame on a 12" thick base rock foundation and is secured to the ground with 2' steel stakes. We did reinforce a few places in the frame with conduit for extra support. The edges are held down with 2" concrete blocks all the way around.
The morning of the storm, I ordered another one :)
