Shade cloth question

[donna13350]

Is anyone aware of any studies done on the height of shade cloth above plants with respect to increase/decrease in percentage of shade ?
I googled it, and just found a couple sites that said 2-3 feet above plants, but nothing with a study or a reason.

I think a lot of that will depend on the angle of the sun hitting the plants. A lot of light and heat comes in from the side, not just straight down.

If anyone is aware of any studies like that it should be the manufacturers of the shade cloth. You could try contacting them.
