Making a witches brew to charge some raw bio char for some soil I'm building. 4 Cups my castings, 1/2 Cup CoWoCo castings, 2 Tbsp Build A Soil Nitrogen Blend, 1 tsp Big 6 micronutrients(Humic and Fulvic acids), 2 Tbsp Malted Barley Powder, 2 Tbsp Kashi Gold and 1 tsp Rootwise Mycorrhizael inoculant. Brew for 24 hrs then soak the raw bio char for about 48 hrs.
