Volatile Organic Compounds Voc

Volatile Organic Compounds (VOCs) are low-molecular-weight organic molecules that readily evaporate at room temperature, forming the aromatic profile of cannabis flowers and trim. In cannabis genetics, VOCs are primarily composed of terpenes—monoterpenes and sesquiterpenes—along with other organic molecules that interact with sensory receptors. VOC profiles vary significantly across cultivars due to genetic expression, environmental conditions, and curing practices. Breeders and researchers analyze VOC composition through gas chromatography to map strain characteristics and predict aromatic outcomes. Understanding VOC behavior is essential for lineage documentation, as these compounds remain relatively stable markers across grow cycles.

Breeders monitor VOC profiles to stabilize aromatic expression across generations and to differentiate cultivar families within strain populations. VOC analysis helps geneticists track inherited terpene ratios and identify phenotypic consistency in seed-based and clone lineages.
