When growing herbs indoors in a container, the most important thing to remember is to provide a growing environment of nutrient rich soil that has good drainage yet holds moisture. Fill the tank with water to check for leaks, using epoxy sealant to fix those present. An inch of small gravel or aquarium stones in the pot bottom ensures adequate drainage. Top with another inch of charcoal chips and add a layer of peat moss followed by a layer of potting soil mix (two parts potting soil with one part perlite or coarse sand). Plant your herbs and keep the soil moist, but don’t overwater.
