Don't put the shade cloth right onto the greenhouse. It will rub the UV coating off the polycarbonate. My frame is a foot above the greenhouse. It is made out of metal pipe and fixtures that I bought at the camping outlet. The current cloth is 40%. I used to have 80% but it was way too dark inside. 40% is still too dark for my high-light plants.
