Instructions were a bit difficult to follow, but once I sat down and REALLY looked at the drawings, it all made sense. We'll see how this handles wind, but for now, I have folded the cloth under the frame, will be putting cinder blocks on the cloth inside the greenhouse and wood along the outside to prevent cloth damage when weed eating. To me, this appears to be a well thought out and constructed unit for the price. We'll see how the plants like it when I get the cinder blocs and raised bed soil in it. Put it together without help, so took me about 5 hours to assemble. Took a few breaks because it was also about 98 degrees out.
