the greeks used mirrors and the sun to burn roman ships, so in my mind it must reflect light

and you want to put a mirror on your plants? So you can break them in and be burnt early? nvm.

they REFLECT 35% of the light that hits them, WHITE MYLAR 95%, Flat White Paint 94%...

so on so for..

Mirrors can also cause heat spots... DO not use them

Aluminum foil reflection rate is like 65% at best..
