It's my first relatively succesful grow, and i just had a question for the experienced growers about aluminum foil. Currently my grow room is lined with aluminum foil i did it as an "ughhh what the heck" kind of thing thinking it might do some good since im too cheap to buy mylar. Now currently my temp varies 34-38 degrees celcius, i know its way too hot but theres no signs of heat stress so im doing my own thing. However i would like to get more wattage into the mix and im wondering does the aluminum foil do any good towards recycling light and alll that. Also how much does aluminum foil affect heat. behind the aluminum foil i have a very pale flat pink paint, am i better off with just that? I dont want to paint the walls white or buy mylar im jus wondering if im better off with or without the aluminum foil and does it do more harm than good?
