What Are Autoflower Weed Seeds?
Autoflower cannabis seeds are strains that flower automatically based on age rather than light-cycle changes. Unlike photoperiod cannabis, autoflowers do not require switching from an 18/6 light schedule to 12/12 to begin flowering.
This trait comes from Cannabis ruderalis genetics, which evolved in regions with short growing seasons—allowing plants to mature quickly and reliably.
Key Advantages of Autoflower Cannabis Seeds
No light-cycle changes required
Faster harvests (30–90 days)
Compact plant size
Ideal for indoor, outdoor, and stealth grows
Beginner-friendly genetics
Multiple harvests per year
Autoflower vs Regular Autoflower Seeds
Growers often ask about the difference between regular autoflower seeds and feminized autoflowers.
| Seed Type | What You Get | Best For |
|---|---|---|
| Autoflower regular seeds | Male + female plants | Breeding & seed preservation |
| Autoflower feminized seeds | Female plants only | Bud production & yield |
If your goal is harvesting flowers efficiently, feminized autoflowers are the best option. For breeding or genetic preservation, regular autoflower seeds are ideal.

FAQs - Autoflower Cannabis Seeds
Are autoflower cannabis seeds worth it?
Yes, autoflower cannabis seeds are worth it for growers who want fast harvests, easy cultivation, and minimal maintenance. They flower automatically, require no light-cycle changes, and finish quickly, making them ideal for beginners, indoor growers, and short growing seasons.
What are the disadvantages of autoflowering cannabis?
The main disadvantages of autoflowering cannabis are smaller plant size, limited recovery time from stress, and slightly lower yields compared to large photoperiod plants. Because autos flower on a fixed timeline, mistakes early in growth can impact final results.
How much yield do autoflower plants produce?
Autoflower plants typically yield between 30 and 150 grams per plant, depending on genetics, grow conditions, and grow length. Modern 60–90 day autoflowers can produce impressive yields, especially under strong lighting and proper nutrition.
Do autoflower seeds need 12/12 lighting?
No, autoflower seeds do not need a 12/12 light schedule to flower. They bloom automatically based on age. Most growers use 18–20 hours of light per day throughout the entire life cycle for optimal growth and yield.
How many times can you harvest autoflower cannabis?
Autoflower cannabis plants can only be harvested once per plant. However, because they grow quickly, growers can complete multiple grow cycles per year, resulting in several harvests annually rather than repeated harvests from the same plant.
Can autoflower cannabis be grown year-round?
Yes, autoflower cannabis can be grown year-round indoors with proper lighting and climate control. Outdoors, they can be grown multiple times per year in warm or mild climates due to their short life cycle and fast flowering genetics.
Are autoflower seeds weaker than photoperiod strains?
No, modern autoflower seeds are not weaker than photoperiod strains. Advances in breeding have produced autoflowers with high THC levels, strong terpene profiles, and potent effects that rival many photoperiod cannabis strains.
