I've just finished building my grow box and i've read somewhere that flat white paint is a good way to reflect light. What exactly is "flat" paint? Do they mean a dull finish, like emulsion, or gloss? Nick
hey fellow grower, i too grow indoors and i found that a plain white low odour emulsion works best. as you dont have any fumes to intoxicate your plants and with emulsion it only takes about 20 minutes to dry.
