Substrate Expression
Substrate expression refers to how cannabis terpene profiles vary based on growing medium composition, pH levels, and nutrient availability during cultivation. While a strain's genetic blueprint determines its baseline terpene potential, environmental factors—particularly soil or hydroponic substrate chemistry—can influence which terpenes are synthesized and in what concentrations. This phenomenon is commonly observed across different phenotypes of the same cultivar grown under distinct substrate conditions. Breeders and cultivation researchers study substrate expression to understand how terroir-like factors affect cannabinoid and terpene outcomes, though genetic expression remains the primary determinant of overall profile.

Breeders monitoring substrate expression can identify which genetic lines show stable terpene expression across varying growing conditions versus those sensitive to substrate variables. Understanding substrate-dependent terpene shifts helps inform cultivation recommendations and phenotype selection for commercial stability.
