Currently I use plain old tin foil for the backing on my terrariums (lame, I know) and I'm looking to upgrade to something much better.
What is the very best kind of reflective backing you can get? I think I heard it was mylar once. Also, where can you buy it? Is it expensive? Is it worth it? I need as much info as possible. Thanks!
