Potency Classification

Potency classification systems categorize cannabis genetics by their cannabinoid profiles and concentrations, primarily THC and CBD levels. These classifications emerged from breeding records and laboratory testing data as cultivators sought consistent ways to document plant chemistry across generations. Common frameworks range from low-potency (sub-5% THC) through high-potency (20%+ THC) categories, with some systems including CBD-dominant and balanced ratios. Classification systems vary by region and testing standards, making direct comparisons across datasets challenging. Breeders reference potency classifications when selecting parent plants to establish predictable offspring chemistry. Understanding these frameworks is essential for seed banks and cultivators managing genetic libraries and breeding objectives.

Breeders use potency classifications to select parent plants with desired cannabinoid ranges and to track trait stability across filial generations. Classification data helps document whether offspring consistently express parent-plant potency profiles or show segregation patterns.
