Leaf hairs (actually called trichomes) are glandular structures that secrete plant alkaloids, like nicotine, to deter insect predation. Generally speaking, the hairier the leaf, the stickier it feels. It's this secreted nicotine that is rinsed away following a rain.
Although I haven't read any study of sunlight diffraction by trichomes, I'm sure they would have some impact.

I noticed the hairy/stickiness correlation with my harvest. It escapes me which variety it was but I remember when I was priming , just after one row my hands were as if I had dunked them in tar . Which by the way took using Comet and a scrub brush to clean my hands.Leaf hairs (actually called trichomes) are glandular structures that secrete plant alkaloids, like nicotine, to deter insect predation.
