Post Harvest Phenotype

Post-harvest phenotype refers to the observable changes in cannabis plant material that occur after cutting and during drying, curing, and storage phases. These modifications include shifts in terpene profiles (through oxidation and evaporation), color changes in flowers and trim, and development of secondary aromas often described as hay, spice, or earthiness. Unlike the living plant's phenotype, post-harvest changes are influenced by environmental factors—temperature, humidity, light exposure, and handling methods—rather than genetics alone. Understanding post-harvest phenotype is essential for breeders and producers seeking consistent product quality and flavor stability across batches. The distinction matters because a strain's dried expression may differ noticeably from its fresh-harvested profile, affecting both breeding records and consumer perception.

Breeders track post-harvest stability and aroma development as part of phenotype selection, as some genotypes demonstrate more favorable terpene retention or aromatic complexity after curing. Documenting how a line's sensory profile evolves post-harvest informs decisions about breeding for storage resilience and secondary metabolite expression.
