mylar, I saw the actual results of a scientific research , unfortunately I never saved it. (Flat) white paint out performs both aluminum foil and mirrors
A very inexpensive form of Mylar is the reverse side of "foil wrapping paper."
You don't want the X-mas theme facing your plants. The shiny side is a very good reflector and doesn't burn spots unlike foil.
Dollar Store for the low low.
