How It Works: Simply add a handful of worms and your organic waste to the bottom tray. The worms will start processing the food. Once the bottom tray is filled add another tray. The worms migrate upward to the newest food source leaving the bottom tray full of nutrient rich compost. As waste is broken down, moisture filters through the system, taking nutrient-rich particles with it. This makes it possible to harvest organic liquid fertilizer right from the spigot.
