Black four tray indoor worm farm

$55.99
Catalog updated 2026-11-04

This black worm farm uses a multi-tray system to process kitchen scraps into nutrient-rich fertilizer. The vertical design allows worms to migrate upward through the four layers as they finish consuming organic waste. It holds about 7.4 gallons of material, making it a manageable size for small households or apartment balconies.

The unit is built to function both indoors and outdoors, providing flexibility for those with limited garden space. By separating the waste into different levels, the bin maintains airflow and prevents the contents from becoming too compacted. This setup helps speed up the decomposition process while keeping the footprint of the bin relatively small.

Constructed for durability, the dark finish helps regulate internal temperatures for the worm colony. The lid fits securely to keep pests out and moisture in, creating a stable environment for composting. It is an effective way to recycle food waste into liquid tea and solid castings without needing a large backyard setup.
