Product Description
Charcoal can be used to "sweeten" soil or water (aquariums, ponds). It is invaluable for drainage in the bottom of pots, and as an additive to home made potting mix.
Excellent for the bottom of non draining planters like tearrariums. It prevents the potting mix from becoming sour.
Good growth can be achieved by mixing 40% charcoal with 60% pine bark for Cattleya and Dendrobium orchids.
