Whats the best thing to use for reflective light?

a white surface is just as good. paint the walls white or buy some foam board at an art store or drug store. whatever you do, do not use aluminum foil, the crinkles cause light to reflect unevenly and can cause hot spots and burn your plants

ive painted the inside black already will that work?
Black absorbs light, you want flat white paint. But you have already painted black so it will take lots of coats of white unless you primer. maybe get on ebay and order some mylar.

You can use those heat/survival blankets that they sell at camping stores.. They are made of mylar & they are cheap too
