Volatile Organic Compound Timing

Volatile organic compound (VOC) timing refers to the developmental window during cannabis growth when aromatic molecules are most actively synthesized and expressed. These compounds—including terpenes, esters, and sulfur-containing volatiles—emerge at different stages: some during vegetative growth, others during flowering, and some only in late maturation. Understanding VOC timing is critical for breeders selecting for specific aroma profiles, as harvest date, environmental conditions, and genetic expression windows all influence which compounds dominate. Lineage records frequently report that parent plants from different geographic origins show distinct VOC production schedules, affecting the final phenotype's aromatic character.

Breeders working in this category prioritize plants that express target aromatic compounds at predictable developmental stages, enabling consistent flavor and aroma in offspring. Selecting for early, mid, or late-stage VOC expression allows breeders to stabilize desired sensory profiles across generations and environmental conditions.
