The humus can be gathered by sieving or after migration of the earthworm and can bu used to enrich a soil or a potted substrate. In this specific system, the earthworms establish their colony in the superior part (the first 15cm), the humus created stays in the inferior part and the percolate which is evacuated in the organic filter is enriching by going through the humus. This kind of earthworm composting is intended mostly for percolate gathering.
