Terpene Synthesis Timeline

Terpene synthesis in cannabis occurs across distinct developmental stages, from seedling through flowering and post-harvest curing. Primary terpenes accumulate earliest in plant development, while secondary and trace terpenes often increase in abundance during late flowering and maturation phases. Environmental factors—light spectrum, temperature fluctuation, soil nutrients—influence the timing and concentration of volatile compound production. Terpene profiles continue evolving during drying and curing, as some compounds degrade while others form through oxidation and enzymatic conversion. Understanding this timeline helps breeders select for desired aromatic phenotypes and informs cultivation practices that may affect final volatile composition.

Breeders monitor terpene expression across growth stages to identify stable genetic markers for aroma type and timing of peak volatile production. This knowledge supports selection for cultivars with consistent aromatic profiles and helps optimize harvest windows for target terpene ratios.
