Extended Flowering Types

Extended flowering types refer to cannabis strains with notably prolonged bloom phases, typically requiring 10-14+ weeks to reach full maturity. These varieties are often encountered in indica-dominant and landrace genetics, particularly from equatorial and subtropical origins where longer photoperiods historically drove selection. Breeders distinguish extended-flowering plants by their slower calyx development, gradual trichome maturation windows, and extended resin-production periods. Documentation in breeding records frequently notes these strains as valuable for cultivators managing controlled environments where flowering duration can be precisely managed. The extended timeline is a heritable trait influenced by both genetics and environmental conditions like temperature and light exposure.

Breeders working with extended-flowering genotypes often cross them with faster-finishing cultivars to create intermediate-duration hybrids, or maintain pure lines for specific market niches. This trait provides extended windows for cannabinoid and terpene development, making it relevant in lineage work focused on chemical complexity.
