Greenhouse snow swept

If I heated it or waited for the sun, I wouldn’t even need to sweep it. I built this with a 5.5 12 pitch. You can get away with maybe a 3 12 pitch. I will change the next model to have the support Purlings to be recessed. I thought having them flat would cradle the snow. I don’t emend think I need any rafters for this span, if heated and inflated. Live and learn
