Cannabinoid & Terpene Reference Data

USA Premium genetics are predominantly bred in California, Oregon, and Colorado, the three states where cannabis breeding has matured most since legalization. Lab data shows that USA-bred strains lead the global market in peak THC numbers and Cookies/Gelato-family terpene complexity. These are the genetics other countries import.
