The Cannabis Microbial Consortium (CMC) has been created over years of controlled experimentation with micro-organisms and the cannabis plant. The CMC is a consortium of facultative anaerobic acid producing micro-organisms, cultured from the cannabis plant’s microbiome. This ensures that the microbes are indigenous to the cannabis plant.
The consortium is a biodiverse product with various beneficial micro-organisms. Its primary purpose is to reintroduce a biodiversity of beneficial micro-organisms back to the plant and soil. Micro-organisms are crucial to healthy soil, plants and life. In soil they help break down organic matter and rock minerals to make the elements (nutrients) bioavailable to the plant while also defending the plant and soil from pests and pathogens. The optimal PH range for most plants is 5 to 7. A more focussed PH range for cannabis is 5.5 to 6.5 meaning cannabis prefers a slightly more acidic soil.
Cannabis is a hungry a plant and is happy consuming large amounts of nutrients quickly. Calcium, Magnesium and Potassium being some of those nutrients required by the cannabis plant in large amounts. To meet those nutritional needs of the plant large amounts of these elements are added to the soil, as these elements are all cations and contain a positive electrical charge, they often overly increase the PH of the soil, thus making various elements unavailable to the plant.
Using acid producing micro-organisms in conjunction with cation rich soils, ensures a balance is obtained.
One of the beneficial micro-organisms isolated and genetically verified in CMC is Paenibacillus Taichungensis (PT). An efficient plant growth-promoting rhizobacteria (PGPR), which competitively colonize plant roots and acts as a biofertilizer.PT produces IAA (indole acetic acid), one of nature’s organic plant hormones. A South African University Laboratory test conducted in September 2019 on a sample of CMC proved a Paenibacillus Taichungensis count of 4.75 x 10⁹ CFU/ml – i.e. 475 000 000 000 (475 Trillion) Colony Forming Units per millilitre.
