Heavy Metals Testing

Heavy metals testing is a critical laboratory analysis that detects the presence of contaminants such as lead, cadmium, arsenic, and mercury in cannabis plant material. This testing falls outside traditional terpene profiling but represents an essential quality and safety assessment in cannabis genetics work. Heavy metals accumulate in plant tissues through soil composition, water sources, and growing conditions rather than genetic expression. Breeders and seed developers working with established lineages often evaluate testing data to understand how specific cultivars or growing environments interact with soil chemistry. Comprehensive heavy metals analysis is now standard in regulated markets, making it an important consideration when documenting strain stability and cultivation safety across different geographic regions.

Breeders use heavy metals testing data to identify cultivars that show lower bioaccumulation tendencies in contaminated soils, informing decisions about which genetics to recommend for specific terroir conditions. This information helps establish baseline profiles for seed preservation and heritage strain documentation.
