The Worm Factory® is a stackable, multi-tray composting worm bin system. Worms begin by eating waste in the lowest tray, and then migrate upward as food sources in that tray are exhausted. By allowing worms to migrate upward, the worms move themselves away from the finished compost that is then ready for your garden.

As waste composts in your Worm Factory®, moisture filters through the composter, dragging nutrient-rich particles with it. This liquid fertilizer, known a leachate, gathers in the collection tray below and can be easily drained from the spigot.
