The Worm Factory is an efficient way to compost. The square stacking bins allow you to put the worms (ordered separately), their bedding, and some food scraps in the bottom and more food waste and junk mail or corrugated box scraps in the top trays. The worms migrate upward in search of food as the supply below is used up. When they migrate, their castings in the bottom tray can be harvested. Worm castings are rich with phosphorus, nitrogen, and many other nutrients and trace minerals, making them an excellent organic fertilizer.

There is a handy spigot on the bottom tray of the Worm Factory to drain the compost tea. This can be used as liquid fertilizer wherever needed, too. The worms in a fully functional 5-tray system use about 5-8 pounds of food scraps a week, and you can harvest one bin of castings about every six weeks. Each set comes with a complete, detailed 16 page instruction booklet, printed on recycled paper with soy ink.

The operational temperatures are between 45 and 85°. The Worm Factory can be used year-round. In the warmer months, place the unit outside in a dry place away from direct sunlight. In the cooler months, place the unit inside; used correctly, it is an odor-free system. Comes with Coconut Coir Brick to give your worms their first "home" while they make castings.

  • Stacking Trays and Base
  • "Worm Tea" Collection Tray
