Full Spectrum Phenotype

Full Spectrum Phenotype refers to cannabis plants expressing a complete or near-complete range of cannabinoids, terpenes, and flavonoids across their tissue. Rather than displaying dominant single compounds, these phenotypes produce measurable quantities of CBD, CBG, CBC, minor cannabinoids, and diverse terpenoid profiles simultaneously. Breeders pursuing full-spectrum genetics typically work with polyhybrid crosses or landrace-derived lines known to retain chemical complexity. Documentation of full-spectrum phenotypes relies on laboratory chromatography (HPLC, GC-MS) rather than visual or organoleptic assessment alone. This classification emerged from breeding programs focused on preserving plant secondary metabolite diversity, particularly in hemp and therapeutic-oriented cannabis development.

Breeders working toward full-spectrum phenotypes typically select parent plants with complementary minor-cannabinoid production and cross them to concentrate genetic traits across multiple biosynthetic pathways. Stabilizing full-spectrum offspring requires multi-generational selection and rigorous testing, as chemical complexity often segregates unpredictably in F1 and F2 generations.
