Swim has a Panasonic speaker that is blown. Swim wishes to turn it into a grow box. What all does swim need to do to turn one speaker box into a grow box? Is it as easy as take the speakers out put something reflective covering on the inside? Swim knows not to use tin foil. Then start the grow process? This will be swims first grow. Swim is going to be using CFLs. Whats a good soil to use?
