Mylar

Can anyone tell me a good local place to get mylar or a good reflective material that doesn't add heat (Not white paint, don't feel like painting 2 growboxes).

take the cheap way out and just buy some big chip bags... like some delicious dorito's the inside of those bags is a really good reflective alternative, especially if you have a small space

That's a lot of chip bags <.<

My boxes are 36Lx24Wx36H, and I have 2 of them. Probably cheaper to just order a mylar roll from HTG.

I heard the reflective Christmas wrapping paper works great but it's June =(
