Late Terpene Expression

Late terpene expression refers to cannabis plants that develop their full aromatic profile primarily during the final weeks of flowering, rather than throughout the growth cycle. This classification describes genetic lines where volatile terpene compounds accumulate and become detectable later in maturation, often correlating with cannabinoid development timelines. Breeders working with late-expressing strains must allow extended flowering periods to capture the complete terpene spectrum intended by the cross. This trait is frequently observed in certain Indica-dominant and landrace-derived genetics, though expression patterns vary significantly based on cultivation environment, harvest timing, and individual plant phenotypes.

Breeders selecting for late terpene expression often extend flowering windows and monitor trichome development closely to time harvest when terpene volatility peaks. This trait is valuable for creating complex, nuanced aromatic profiles that develop through selective pressure rather than early-stage terpene dominance.
