  • Patent number: 3961603
    Abstract: A small-scale habitat for the cultivation of earthworms is designed for the optimum production of live worms, eggs and worm castings. The habitat comprises a plurality of superimposed, stackable containers with perforated bottoms and inward projections at their upper flanges. These projections sustain the weight of the upper containers, admit air to each individual container and permit feeding and breeding activity by earthworms at all levels of the stacked assembly; the movement of the earthworms from one level to another being facilitated by the aforementioned perforations in the bottoms of the containers. The bottom-most container has an unperforated bottom and is adapted to hold water in a matrix of pebbles or crushed stone for the control of the moisture content of bedding, suitably peat-moss or coarse earth, in the superior containers.
