I'm in the process of making vermi extract. It is a different process then making a oxygenated tea from the worm casts. I put the castings into a tightly stitched burlap sack the I use my power washer to knock the microbes off into a barrel. Extract can stay alive for up to 18 months. The problem being is the water in my well has frozen solid so no water 😔😔😔
Anyway the joys of worm farming in Ireland🤘
