Each of the bedding materials that come in the Worm Factory Refill Kit are in the same convenient size packages that originally came with the Worm Factory 360 composter. They can also be used with the Worm Factory Standard composter. When used as instructed this kit contains enough materials for at least 8 composting trays. Bedding materials play an important role in reproduction rates and impact the manageability of the Worm Factory. They are essential for air space and moisture control. Bedding materials should compose at least 50% of the material you add to the feeding trays. The pumice and coconut coir prevent odors from forming in the Worm Factory360 and the Worm Factory Standard by providing carbon, without which the system would sour. They also keep the materials in the tray from packing tightly. This promotes increased air flow and free movement of the worms. Minerals provide grit for the worms and food for the microbes that are working sight unseen in the Worm Factory, helping to breakdown the food for the worms and ultimately providing nutrient rich vermicompost for optimal plant growth.
4 - 2 cup packages of pumice
