Terpene Production Timeline

Terpene production in cannabis is not constant throughout the plant's life cycle. Biosynthesis begins during vegetative growth, accelerates during flowering, and peaks around mid-to-late bloom before declining in the final weeks before harvest. Environmental factors—light intensity, temperature, humidity, and nutrient availability—significantly influence both the timing and volume of terpene accumulation. Understanding this timeline is crucial for breeders selecting parents, cultivation timing, and preservation strategies, as harvest date directly affects the terpene profile's composition and concentration. Different terpene compounds follow distinct production curves; some accumulate early while others emerge only in late flowering.

Breeders monitoring terpene production timelines can identify cultivars with desired aromatic peaks, breed for extended terpene retention in late flowering, or select for rapid biosynthesis in shorter seasons. Selecting parent plants based on their terpene expression windows helps stabilize desired profiles across generations.
