Earthworm Castings – Fine Grain


Microbe-rich castings from juvenile earthworms, screened from finished vermicompost through a 1/8” inch mesh hardware cloth.

With less potential for clogging, these finer grain castings from younger worms are ideal for preparing liquid extracts or actively aerated teas to more economically supply a broad diversity of beneficial soil microorganisms.

In the GEOTEA System, 1 cubic ft / 40 lb of castings are used for each 250 gallon batch.
