Amen to that! I took off one of the tarps I had on the run over the winter, and am amazed at how much light they didn't have.Clear roofing is one of those "Climate matters" things.
It's great for people in cool climates who need to maximize sunshine. In my climate it turns the chicken housing into a chicken rotisserie
I'm going to be putting clear roofing panels on soon, but will keep a tarp handy if I need it to cut down the light/heat.
