New atuoflower cabinet

hey guys i pretty much have all the things i need for my new two door cabinet im putting together for my atuoflowers this is my first actual cabinet just trying to get som pointers my first question is what should i use as a liner on the inside to keep the cbinet from glowing like a big jack'o lantern????

what are you building it out of.
what light are you using.
how big is it.
where is it going.
what kind of doors/hinges.

didnt think had to be specific just thought it would be a brand of foil or something its a 3ft cab its like a heavy duty plastic im useing a 150wat hsp may add two 40watt cfl ummm shit is going in my closet i dunno what other info ud need but what i was think was maybe get those car sunlight reflectors or something and line the inside of my cabinet

ill throw pics up tmrw
