Some notes on finding supplies
Activated Charcoal: Your best bet for finding activated charcoal is an aquarium or pet supply store. They sell this charcoal in bulk packages. This is the type of charcoal used in Brita filters and air filter masks as well. You only need a few tablespoons of the stuff for one moss garden.
Peat Moss and Potting Soil: These are common and can be found in at most garden centres.
Pebbles: You can find pebbles on the ground, or you can buy them in a store. Aquarium stores sell pea gravel that is the perfect size. The stones should be quite small, about the size of lentils or raisins. You need enough pebbles to create a solid layer in the bottom of your container. Wash your pebbles well before using them.
