Fast-flowering cannabis seeds offer a unique advantage to growers who would like to produce high-quality, resin-rich yields sooner. Whether you’re a cultivator looking to produce multiple harvests per year, or simply prefer faster results, our varied collection of fast-flowering seeds offer all the benefits of growing your favorite strains from the comfort of home—but in a more efficient way.
Fast-flowering cannabis seeds are a convenient option for cultivators looking for a way to produce resinous yields in a shorter time frame without compromising on quality. Cannabis seeds are considered fast-flowering if they have a flowering time of approximately 55 to 65 days or fewer.
Many fast-flowering cultivars are created by crossing photoperiod and autoflowering plants that include ruderalis lineage, though this is not always the case. Some photoperiod plants are simply bred to flower quickly without expressing autoflower traits.
Fast-flowering cultivars often combine strong potency, developed terpene profiles, layered flavors, and natural resilience.
By shortening the flowering phase compared to traditional photoperiod plants, fast-flowering seeds appeal to growers who value speed and efficiency.
Below is a quick overview of what you can expect.

Fast-flowering cultivars to consider
How Quickly Do Fast-Flowering Seeds Grow?
Fast-flowering cannabis seeds typically shorten flowering time by one to five weeks, depending on the cultivar. Standard photoperiod plants often take around 21 weeks from seed to harvest, with an 8 to 12 week flowering window. Fast-flowering options can be ready in as little as 16 to 20 weeks, with flowering periods closer to 6 to 8 weeks.
What Are the Benefits of Fast-Flowering Seeds?
Fast-flowering seeds work well for growers in regions with shorter seasons or anyone looking to increase yearly harvest potential. They do not change the fundamentals of cultivation, but they offer clear advantages.
Shorter cultivation time that can reduce flowering by two to five weeks
Better adaptability to cooler climates and unpredictable weather
Potential for multiple harvests within a single outdoor season
Reduced exposure to pests and disease due to quicker maturity
Lower energy costs for indoor growers through shorter lighting and climate cycles
Growing Tips for Fast-Flowering Seeds
Photoperiod fast-flowering cultivars still require a light schedule change to trigger flowering
Nutrients should be delivered on a tighter timeline due to the shorter lifecycle
Training methods like Sea of Green can help maximize yields
Stable temperatures between 70 and 85°F and humidity between 40 and 60% support healthy growth
