Plant Chemistry Testing

Plant chemistry testing refers to laboratory analysis of cannabis flower and biomass to quantify cannabinoid profiles, terpene composition, and residual solvent or contaminant levels. These tests measure compounds like THC, CBD, CBG, and trace cannabinoids, along with volatile organic compounds that contribute to aroma and flavor. Chemistry data informs breeding decisions, helping growers and breeders understand how genetic lineages express specific phytochemical ratios. Testing protocols vary by jurisdiction and lab, affecting how results are reported and compared across seed banks and cultivation records. Accurate chemistry profiles are essential for documenting strain stability and predictability in multi-generational breeding programs.

Breeders use chemistry testing to select parent plants with desired cannabinoid and terpene profiles, establish baseline genetic expressions, and track chemical consistency across generations. Repeatability of chemistry results helps validate F1 hybrids and stabilized lines before commercial release.
