Will weed barrier work as a shade cloth?

My cukes can get stressed during July and August, the hottest months of the year in Michigan. Will black weed barrier work as shade cloth or will too much heat build up behind it and further stress the cukes?

My fava bean plants now formed pods. It is getting around twelve hours of sunshine on the roof. I am worried that the weather is now getting too hot, in Egypt. Should I move it back to a shady balcony or does it still need a lot of sun to grow?

A couple of my succulents have bent as they've grown over the past year or so. I suspect they're "reaching" for sunlight (they're next to a window, bending southward, and I live in the northern hemisphere -- though it's possible this is just a…
