Flowering Time Extended

Extended flowering time refers to cannabis cultivars that require longer periods—typically 10-14 weeks or more—from the initiation of flower to full maturity and harvest readiness. This trait is often observed in landrace genetics, certain Sativa-dominant lines, and some deliberate breeding selections. Extended flowering periods can correlate with increased resin production and complex cannabinoid/terpene development in some lineages, though causation varies by genetics. Breeders document flowering duration as a critical cultivation parameter, distinct from terpene profiles themselves. Understanding flowering timeline is essential for crop planning, resource allocation, and phenotype stability across growing environments.

Breeders selectively work with extended-flowering lines to explore potential secondary metabolite complexity and genetic diversity from slower-maturing germplasm. Conversely, many commercial breeding programs actively select *against* extended flowering to reduce cultivation costs, making this trait valuable primarily in preservation and landrace-focused breeding contexts.
