When it comes to choosing the right cannabis genetics, one of the first decisions every grower faces is whether to grow photoperiod strains or autoflowering strains. Both have unique advantages and challenges—and knowing which is best for your goals can make the difference between a successful harvest and wasted potential.
At MOSI EXOTIX, we specialize in breeding and testing elite cannabis genetics. Below, we’ll break down the differences between photoperiod and autoflower genetics so you can make an informed choice—and find the strains that fit your grow.
Photoperiod strains depend on light cycles to trigger flowering. In nature, they begin to flower when days shorten and nights lengthen. Indoors, growers typically switch the light cycle from 18/6 (veg) to 12/12 (flower) to initiate bloom.
Control: You decide when to flip plants into flower.
Bigger yields: With a longer vegetative phase, plants can grow larger and deliver heavier harvests.
Training flexibility: Respond well to topping, low-stress training (LST), and SCROG setups.
Genetic variety: Most premium strains—like Love Chocolate Feminized Seeds—are photoperiods.
Longer grow time (can take 4–5 months total).
Requires strict light cycle control indoors.
Best for: Growers looking for maximum yield, terpene richness, and control.
Autoflowering strains flower automatically after a certain number of weeks, regardless of light cycle. These genetics were developed from Cannabis ruderalis, known for its ability to thrive in harsher climates with shorter summers.
Speed: Ready to harvest in as little as 8–10 weeks from seed.
No light cycle changes: Stays in the same lighting schedule from start to finish.
Compact size: Great for small grow spaces or stealth grows.
Beginner-friendly: Less sensitive to mistakes in lighting schedules.
Smaller plants → lighter yields compared to photoperiods.
Limited training options.
Less genetic diversity compared to photoperiods.
Best for: Growers who want fast harvests, discreet setups, or easy-entry genetics.
Photoperiod vs Autoflower
Flower trigger | Light cycle (12/12) vs Automatic (time-based)
Harvest time | 4–5 months vs 8–10 weeks
Yields | Higher potential vs Lower overall
Plant size | Larger vs Smaller, compact
Training | Works well with topping/SCROG vs Limited surface topping
Best for | Experienced & commercial growers vs Beginners, quick harvests
🌿 Which Is Right for You?
The choice depends on your goals:
If you want top-tier flavor, heavy yields, and full control, go with photoperiod genetics like our Morning Coffee Feminized Seeds or Love Chocolate Feminized Seeds.
If you need fast turnaround and low-maintenance plants, autoflower genetics might be the perfect entry point.
Either way, MOSI EXOTIX ensures every strain is bred, tested, and selected for elite performance and unique terpene profiles.
Choosing between photoperiod vs autoflower genetics isn’t about better or worse—it’s about what’s right for your grow. Autoflowers deliver speed and simplicity, while photoperiods reward patience with higher yields and richer terpene expression.
At MOSI EXOTIX, we’re here to guide your grow—whether you’re a beginner just starting out or a commercial cultivator looking for tested, elite strains. Explore our full Genetics Collection to find the perfect fit for your cultivation journey.
