In powder form, naturally fermented and decomposed in the caves of Indonesian archipelago for many-many years, through the years the nitrogen and organic matters will mix with the cave's soil and cave's ground stones, the lower sediment will increase in Phosphate content. Difficult to find and gather, can be used directly to the plant's soil. What we do, is to locate certain caves that contain certain soil and ground stones within the compositions that we are looking for, and then do the laboratory test to ensure our findings prior to actual collection process.
