Cbd Cbd Ratio

The CBD:CBD ratio classification refers to cannabis plants expressing elevated cannabidiol (CBD) levels relative to tetrahydrocannabinol (THC). This category encompasses strains typically containing CBD concentrations of 1% or higher, often with THC levels below 0.3% in jurisdictions where legal thresholds apply. Breeding programs targeting this classification emerged from medical and research cannabis cultivation practices, where breeders selected for CBD-dominant phenotypes across generations. The ratio itself becomes a foundational metric in cultivar development, allowing breeders to establish stable lineages with predictable cannabinoid profiles. Documentation of CBD:CBD ratios helps growers, researchers, and seed companies communicate about plant chemistry without relying on effects-based language.

Breeders working in CBD-dominant categories use cannabinoid ratio testing to select parent plants and stabilize offspring phenotypes. Achieving consistent high-CBD expression often requires crossing established CBD-rich genetics or backcrossing to stabilize recessive cannabinoid-synthesis traits across multiple generations.
