The Worm Factory-Three Tiered Worm Factory

5-year warranty on parts and workmanship.  The newest pets on the block, and the hardest workers!  Your worms will be the easiest animals you've ever cared for, and they make your composting easy.  Just feed them your food scraps, and they'll make rich, black worm castings.  Nutrient rich, biologically diverse, worm castings add life to your soil, reinvigorating your plants.  The Worm Factory® is a stackable, multi-tray composting system. Worms begin eating waste in the lowest tray, and then migrate upward as food sources in the lower trays are exhausted. By allowing worms to migrate upward, the worms move themselves away from the finished compost that is then ready for your garden. The Worm Factory is not just for the experienced gardener, it is designed so that people of all ages and gardening experience can operate it.  Year-round, odor-free operation.  Houses eight to twelve thousand worms that consume 5-8lbs of food per week. Built in "worm tea" collection.   16-page instructional booklet with easy-to-use photos and illustrations.  Easy to assemble and to manage.  Add-on tiers available for expansion.  Available in black, terracotta & green.  "Quick-Tips" lid for easy reference.  Includes: 3-tiered Worm Factory
