Worm composting is an incredibly efficient way to convert kitchen waste into nutrient-rich compost for your garden. The GREEN GREEN Gusanito® Worm Composter design allows food waste to be put into upper trays separating it from finished compost in the lower trays. Simply fill the bottom tray with red wiggler worms, bedding and food scraps. As the worms finish digesting, they will migrate upward into the tray above, leaving rich castings behind. In full operation, the Gusanito® Worm Composter may house 10,000 to 12,000 worms (approx 10 lb), consume 5 to 8 pounds of food a day, allowing you to harvest a full try of castings per month. Each unit comes with full instructions and everything you need to get started. The GREEN Gusanito® Worm Composter is made in China and constructed from high quality recycled plastic, with a limited 5 year warranty on materials and workmanship. It is very simple to assemble and can be stored inside or outside. Measures 16 X 16 X 28, height depends on number of trays used
