Original Design. The Worm Factory's stackable, multi-tray design makes it the most efficient worm bin composter around. Worms begin eating waste in the lowest tray, and then migrate upward in search of food. Use it indoors or out.
Four stackable trays and base with drain
16-page instructional booklet and DVD
Available in Green, Terracotta, and Black
Additional trays can be added to expand capacity
Accessory Kit (thermometer, scraper, rake) and soil amendments
10 year manufacturer's warranty
Once the worms have finished your original trays, add another tray with fresh material. The worms will migrate up as they finish the lower tray and find your newer kitchen waste and tray components. As many as 8 trays can be used over the sturdy base.
