if the snow stuck to my glacier greenhouse so that I had to push it off, it will stick to a hoop house made from cattle panels for sure, or a carport tent. It may not *always* or even often stick, but sometimes it will. If you want something that’s guaranteed to slide off, a true A-frame seems to me like your best bet.
Yeah, I'm really thinking of a good A-Frame design because I don't want to brush/shovel off snow after every storm. I was thinking a hoop house with a domed top would work, but with a wet snow it would probably stick to the plastic and build up.
