Chemotype

Chemotype is the broad cannabinoid-ratio classification of cannabis: Type I (THC-dominant), Type II (balanced THC:CBD), and Type III (CBD-dominant). Chemotype is set by genetics and is more stable than chemovar (which also incorporates terpene profile and can shift more with environment).

Example: Type II chemotypes give you both THC and CBD in usable quantities.

Etymology: From 'chemical' + 'type'; standard cannabis-science taxonomy since the 1970s.
