    I've noticed that several people have mentioned the use of mylar for light reflection in their grow chambers. I've looked for this @ several places(aquarium shops, home improvement stores, etc.) but I have yet to find any. In fact, the people at those places are pretty much clueless about what I'm talking about. The best suggestion I was given was to use some sort of reflective paint. Where do you all get your mylar(or similar material), and how much was it?(I'm in the US, if that makes any difference)

    Thanks,
    elarwhis

    intensive hobby stores usually carry it. It is rather expensive though, like $50 for a 48" X 25' roll. I found mine at a hydroponics store. You can also use the shinier side of aluminum foil.

    Well, if it's that expensive, I'll probably end up using aluminum foil. Thanks.

    Yeah, when i was just restocking, Ebay ended up being the cheapest. One of those places that says "All sales are discrete. We don't want to know what you are growing. If you tell us, and it is illegal, we will not sell your our product..." LOL

    Aluminum foil really doesn't do the same thing. It's more diffuse than specular. But it may not matter, depending on your usage.

    Mylar does make a good insulator, though, if that's important. It helps keep my lowland terrarium much warmer than the surroundings in the winter.
    There's no 'a' in perlite.

    I think I'm going to order it from here:

    http://www.discount-hydro.com/mylar.asp

    It comes in 4' rolls, which is the size I need; the stuff I saw on ebay was only 3'.
