Vernalization
Vernalization is not a terpene, but rather a physiological process in cannabis cultivation where plants experience prolonged cold exposure to trigger flowering. Some breeders intentionally subject photoperiod-sensitive strains to cold periods—typically 2-4 weeks at temperatures between 40-50°F—to simulate seasonal transitions and induce reproductive development. This technique is often employed when growing long-photoperiod cultivars in controlled environments or when accelerating breeding timelines. The process can influence terpene expression and cannabinoid profiles by stressing the plant in controlled ways, though individual responses vary by genotype. Understanding vernalization remains relevant for breeders working with heirloom or landrace genetics that retain strong seasonal flowering cues.

Breeders use vernalization to reliably trigger flowering in strains with strong photoperiod dependency, reducing unpredictable vegetative cycles. This practice is particularly valuable when stabilizing new crosses or maintaining genetic lines that require environmental cues to enter reproductive phases.
