Full Spectrum Testing

Full spectrum testing is a comprehensive analytical approach that profiles multiple cannabinoids, terpenes, and other phytochemical compounds present in a cannabis sample, rather than measuring only THC and CBD. Laboratories performing full spectrum analysis typically quantify major cannabinoids (CBN, CBG, THCA, CBDA) alongside minor compounds and volatile terpene profiles. This methodology provides breeders and growers with detailed chemical fingerprints useful for understanding cultivar consistency, phenotypic variation within seed lines, and preservation of strain-specific terpene signatures across generations. Full spectrum data differs from targeted testing, which isolates specific compounds of interest. Regulatory frameworks vary by jurisdiction regarding which compounds must or may be included in mandatory testing panels.

Breeders use full spectrum testing to identify and stabilize desired cannabinoid and terpene ratios within populations, track phenotypic consistency across seed generations, and document baseline chemical profiles for heirloom or stabilized lines. This data supports selective breeding decisions and helps maintain strain identity when working with limited or diverse germplasm.
