Terpene Development Cycles

Terpene development cycles refer to the temporal progression of volatile compound accumulation throughout a cannabis plant's lifecycle, from vegetative growth through flowering and maturation. These cycles are influenced by photoperiod, temperature fluctuations, nutrient availability, and plant genetics, with different terpenes expressing at different developmental windows. Early-stage plants typically show lower terpene concentrations, while peak terpene expression commonly occurs in late flowering as resin glands mature. Understanding these cycles allows cultivators and breeders to identify optimal harvest timing relative to desired aromatic profiles. Terpene ratios and complexity shift as plants age, meaning a strain's aromatic character at week 6 of flowering may differ significantly from week 9.

Breeders working with terpene development cycles select parent plants that produce stable, predictable aromatic progressions across multiple generations. By tracking terpene expression timing across flowering phases, breeders identify genetic markers for early-expressing versus late-expressing chemotypes, enabling selection for either rapid terpene maturation or extended aromatic complexity.
