Worm Factory®

Environmentally Minded Urbanites and Gardeners are Happy to Invite These Guests to Dinner

Vermicomposting with this worm bin can't be simpler.

Three Tray Worm bin seen sitting right on the deck close to the kitchen. Can also be used inside. Extra Trays are available if you need to expand, or buy the 4-tray or 5-tray for large amounts of kitchen waste.

Here we have some of the planet's most lowly creatures taking some of our kitchen scrapes and turning it into fertilizer. Bacteria and other organisms break down food scraps buried in the bin maintained at proper temperature and moisture levels. Then the worms get to work, eating everything in their path-waste, organisms, and bedding. Afterward, the worms excrete a soil-like rich, dark humus. The worm castings are consider by most Master Gardeners to be the very best for your garden and house plants.

With ordinary worm bins, sorting out undigested scraps can be a messy, inconvenient chore. The Worm Bin Factory does the sorting for you, automatically separating food scraps from finished compost. 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 nutrient-rich castings behind. It couldn't be easier or cleaner. No mess. No unpleasant odors, you will get a bit of an earthy smell.

In full operation, The Worm Factory bin houses 10,000 to 12,000 red wiggler worms which consume 3 to 8 pounds of food a day, allowing you to harvest a full tray of castings every month.

Each Worm Factory comes with full instructions and everything you need to get started. The Worm Factory is made in the U.S.A. and includes a 5 year limited warranty, on materials and workmanship. Constructed from high quality recycled plastic, using our exclusive molds, it is simple to assemble and can be set up either inside or outside.
