No don't use either - mirrors eat your light, or at a push use the dull side of the tinfoil (not the really reflective side as this can burn your plants). Best to use Mylar or something like that (you can get it cheap on ebay), but I've heard bare white walls are a really good reflector. Just plain white paint, if you want it on the cheap (as we all do).
