Flowering Time 12 14 Weeks

Flowering time of 12–14 weeks refers to cannabis cultivars that require approximately 84–98 days from the initiation of flowering until harvest maturity. This range typically describes photoperiod-dependent strains that need a 12/12 light cycle (or natural seasonal darkness) to trigger and complete reproductive development. Breeders working in this category often select parent lines from extended-bloom heritage, including certain indica-dominant hybrids and pure landrace expressions. Cultivars in this window are commonly associated with denser bud development and extended terpene/cannabinoid maturation phases. Documentation of exact timing varies by growing environment, nutrient regimen, and phenotypic expression, making this classification a general reference rather than a fixed guarantee.

Breeders targeting longer flowering cycles often cross for desirable secondary metabolite complexity and structure traits that benefit from extended bloom duration. This timeframe is frequently selected when breeding cultivars intended for indoor controlled environments, where extended photoperiod schedules are manageable.
