Vermicompost

Vermicompost is a soil amendment produced through the controlled decomposition of organic material by earthworms, primarily red wigglers (Eisenia fetida). Unlike traditional compost, vermicompost is created in lower-temperature, aerobic conditions within contained systems, resulting in a nutrient-dense, microbially active product. Cannabis cultivators working with vermicompost often incorporate it into growing media to enhance soil structure, water retention, and microbial populations. The finished product typically contains elevated levels of plant-available nutrients and beneficial microorganisms compared to raw organic amendments. Vermicompost is commonly used as a base ingredient in living soil systems and regenerative cultivation protocols.

While not a breeding trait itself, vermicompost is relevant to phenotype expression and plant vigor testing. Breeders and cultivators use consistent vermicompost-amended media to standardize growing conditions, allowing more reliable observation of genetic traits across generations and reducing environmental variables in phenotype documentation.
