    Cheap replacement for mylar!(?)

    so i was talkin to my construction worker buddy the other day about the costs of mylar. i told him what i needed it for (lighting) and he told me that it was hella expensive. but he brought to my attention the lays potato chip bag sitting on the coffee table.

    he reminded me that the inside of most potato chip bags are really shiney!

    i didn't have any mylar to compare it to, but i'm pretty sure it'd do the same job. it was certainly more reflective than aluminum foil (which i've seen some people use).

    unless someone here can offer a technical explanation as to why it wouldn't work?

    99 cents can buy you about one square foot and then some of potato chip bag (im told it's made of polyethylene terephthalate or PET). that sounds like a hella cheap way to make the walls of your growbox/closet light reflective, no?

    any thoughts?

    And for $1.50 to $2.00 you can buy mylar camping/emergency blankets from just about anywhere. They are about 4 foot by 7 foot. It would take a lot of .99cent potato chip bags to equal them.lol Walmart and Kmart and Target sell them in the camping sections.

    Maybe it is my lack of experience in this but why not simply run to the glass store and have them cut you custom size mirrors to line your grow box?

    My father in law works at a glass works and told me he could get me any size cuts of scrap mirrors for a couple dollars a square meter. I was thinking of lining my first grow box with them.

    Maybe I am over looking the obvious, mirrors are more reflective correct?

    Wrong! Mirrors are not a good choice. They are known to put out hot spots which burn plants. Flat White Paint or Mylar or astrofoil are the choices I would go with. I myself use astrofoil.
