Cbd Thc Ratios

CBD-to-THC ratios represent the relative proportion of cannabidiol to tetrahydrocannabinol within a strain's profile, measured through laboratory analysis. This ratio is a key breeding and selection criterion rather than a terpene itself, but it fundamentally shapes how cultivars are categorized and developed. Lineage records frequently report ratios ranging from 1:1 (equal parts) to 20:1 (CBD-dominant) or higher, with some strains containing negligible CBD. Breeders working across different markets and regulatory frameworks have prioritized ratio stability as a heritable trait, making it central to strain identity and predictability.

Breeders select parent plants and stabilize offspring specifically for consistent CBD-to-THC ratios, as this trait is largely determined by genetics and relatively stable across grows. Ratio targeting has enabled the development of distinct cultivar families—high-CBD, balanced, and THC-dominant types—each serving different cultivation and consumer segments.
