Extended Flowering Phenotype

Extended flowering phenotype refers to cannabis plants that require longer bloom cycles than typical varieties, often 10-14 weeks or beyond standard 8-9 week expectations. This trait appears across multiple strain families and is influenced by both genetics and environmental factors like photoperiod sensitivity. Breeders working with extended flowering lines often note delayed trichome maturation and prolonged secondary metabolite development. The extended timeline can affect cannabinoid and terpene profiles, though individual results vary significantly based on growing conditions. Understanding flowering duration is essential for cultivation planning and breeding selection, particularly in regions with seasonal constraints.

Breeders selecting for extended flowering phenotypes often pursue them intentionally to develop complex terpene profiles or specific cannabinoid ratios that benefit from longer maturation windows. This trait is frequently crossed into indica-dominant or landrace-influenced lines where extended bloom periods are already documented in lineage records.
