A superb source of organic nitrogen, phosphorus, calcium and magnesium. A byproduct of the West Coast crab harvest, enhances beneficial soil microorganism populations due to its rich chitin content. These microorganisms exude enzymes known as chitinases, which break down the chitin shell of bad microorganism exoskeletons, an all-natural soil pest control biopesticide! The microorganisms are produced by the plant as a defense mechanism. This stimulates the immune system of the plant resulting in higher terpene and cannabinoid content. The coarse texture is ideal for improving aeration, drainage and overall soil tilth.
