Late Flowering Secondary Metabolites

Late Flowering Secondary Metabolites refers to a classification of chemical compounds—including cannabinoids, terpenes, and flavonoids—that accumulate primarily during the final weeks of the flowering cycle. Breeders and researchers recognize that certain strains exhibit delayed or extended production of these compounds, particularly cannabinoids like CBN and complex terpene profiles, rather than front-loading them early in bloom. This trait is often attributed to genetic factors controlling metabolic timing and enzyme expression patterns. Understanding this family helps breeders select for extended harvest windows and nuanced chemical maturation profiles. Documentation of these patterns is valuable for standardizing cultivation practices and studying cannabinoid biosynthesis variation.

Breeders working with late-stage secondary metabolite production use this trait to extend optimal harvest windows and develop lines where cannabinoid or terpene complexity peaks later in flowering. Tracking this characteristic across generations helps stabilize desirable maturation timing and supports research into the genetic architecture controlling secondary metabolism.
