 Soil light absorption, subsequent drying, and how to prevent it?

I've heard of people mulching the surface of their planters with various things, such as coco coir or certain rocks.
It seems rational to me that you would want to use a white stone to reflect as much light as possible.
Is this commonplace and I just don't know it? Because it seems a nobrainer that black soil is going to soak up light energy and dry out faster.
Do people just use perlite as a top layer, or is it some other kind of rock that I see in this role? And are there downsides?

Indoor, outdoor, or both?

Oh, my bad, I meant indoors under artificial lighting.

I don't see why white rock would not work. As long as it does not somehow effect the pH, like a limestone rock. Many people cover their pots with a white sheeted material or other reflective materials.

Cool... it seems pretty reasonable to figure out a way to utilize that space directly under the plant for light reflection! I could just cut some floating cd-shapes of reflecting material I guess... hmmm.

straw works really well and it breathes so your roots wont rot.

Thanks, this is the sort of thing i was worried about! Straw sounds like a good solution, thanks. I'll see if I can get some of the sea straw my mom was using to mulch her gardens when I go down there.

Make sure it is pest free.
