Just pull your finished compost from the lower trays. Creates nutrient-rich fertilizer for houseplants and gardens. The moisture captured in the bottom tray is also a fantastic liquid fertilizer known as "worm tea". Complete instructions for easy set up and management of an odorless bin year round, indoors or out.
