so my friends got this little grow box and he is debating wether to paint it white inside or use aluminum foil. he does not want to spend money. ok so while at home i was chillin with my son and he got thirsty. so i walked over to the kitchen and picked up a capri sun.the color of the pouch reminded me of the topic. so i looked up online what the capri sun pouches are made out of. CAPRI SUN pouches are polyester-reverse side printed to aluminum then laminated to polyethylene (a plastic polymer). the material is also very reflective. i stood it side by side next to aluminum foil and a white wall surface. the pouch proved to be more effective in reflecting light. i hope some one tries this and gets back at me. do some reasearch and tell me what you think
