which is better, painting the grow room white or lining the walls with aluminium foil?
i've read that painting white better and that only use aluminum as last resort, iz not very reflective
well, given only those two choices, i would assume painting white is better... however, the real answer is neither.
Get Mylar. It reflects light like nothing else ive ever seen.
If there is a hydroponic or garden store in your area, they will most likely sell it. If not, i know for a fact it can be bought on the internet very easily as long as there's nothing sketchy about you getting a big poster sized roll-package in the mail.
White is good, Mylar is king and foil is a waste of money.
