Growth Stages

Growth stages refer to the distinct phenological phases cannabis plants progress through—from seed germination through seedling, vegetative, pre-flowering, flowering, and maturation. Each stage involves documented shifts in cannabinoid and terpene production, plant morphology, and nutrient demands. Breeders and cultivators track these stages to optimize harvest timing, predict final chemotype expression, and maintain consistent genetics across generations. Understanding growth-stage physiology is foundational to cannabis breeding work, as terpene profiles and cannabinoid ratios often shift measurably as plants mature. Environmental factors (light, temperature, humidity) interact with genetic potential during each phase, influencing the final plant phenotype.

Breeders use growth-stage monitoring to identify stable phenotypes, select for desired maturation timelines, and predict chemotype outcomes before full flower completion. Seed producers and clone libraries document stage-specific traits to ensure accurate lineage records and consistent offspring expression.
