I'm wondering, who leaves shade cloth up all year and why? Who is able to put the cloth on the outside and raise it above the roof, and how? Does anyone open and close their cloth during the day? I used to start taking down my inside hung cloth late summer as my north west grnhs was very light challenged, and start to put it back up as needed in the spring. I'm thinking for my new grnhs with the cloth outside, that leaving it up all year may offer a little frost protection as well. Right now as a temporary bandage till the sun moves over head, and we see if the north roof needs shading, we put up a huge piece of black 60%, way to dark. Once we track the sun over the next 6 weeks, I'll order aluminet 40 or 50%.
