Khyber is correct.
There's not a lot of help light-wise and the under-leaf is a hard sell, for photon absorbtion.

I cover my coco to thwart thrips n Fungus gnats n Whitefly.
They all reproduce in soil.
I use reflective material while I'm at it because, well, "it can't be a bad thing".
And specular reflections do seem to confuse the whitefly.
