Flowering Time 9 10 Weeks

Flowering time of 9–10 weeks describes cannabis cultivars that complete their reproductive cycle from initiation of flowering to full maturity in approximately 63–70 days under standard 12/12 photoperiod conditions. This timeframe is commonly observed in many modern hybrid and photoperiodic cultivars, representing a middle ground between faster-finishing and extended-cycle varieties. Breeders often select parent plants with this finishing window to balance yield potential, cannabinoid development, and practical cultivation timelines. Lineage records frequently report this range in F1 hybrids and stabilized IBL lines developed for commercial and small-scale production environments. Environmental factors—including light spectrum, temperature, and nutrient availability—can modulate actual finishing time within this window.

Breeders working in this category prioritize this flowering duration because it aligns with typical indoor seasonal cycles and outdoor harvest windows in temperate zones. Selection for this trait involves phenotypic screening across generations to identify consistent, stable finishers within the 9–10 week range.
