Here's my method.. I take a few handfuls of finely broken down WC'S & stuff them in an old sock/ panty hose. Submerge in a 5 gallon bucket with an aquarium bubbler & h20 that's been bubbling at least 48 hours. I use rainwater only btw. I then add a tbls. Or 2 of blackstrap molasses to help the Microbes along. Same approach for Bat Guano Tea or Manure Tea. Some of my buckets have been running for 7 years now. I just top them off when they dip low.
