Fastflowering cannabis seeds are the perfect choice for those looking to buy marijuana seeds with a short cultivation cycle, rapid flowering, and high yields. These strains are popular among growers thanks to their quick development and adaptability to various conditions. At Sunny Seeds, we offer a wide range of fast-flowering strains that guarantee results.
What are fastflowering cannabis seeds
Fastflowering cannabis seeds (also known as Fast Version or Fast Flowering) are hybrids that combine the genetics of autoflowering and photoperiod strains. These seeds were developed to shorten the flowering phase without losing the ability to control the light cycle. They begin flowering after the reduction of daylight hours, like regular photoperiod strains, but mature 2–3 weeks earlier.
On average, fast strains have a flowering period of 6–7 weeks, allowing you to harvest before rains, cold temperatures, or mold set in. These seeds are ideal for outdoor growing in regions with short summers, as well as for indoor cultivation where speed matters. Thanks to carefully selected genetics, fast-flowering varieties retain high THC potential and rich flavor and aroma profiles.
Fast strains should not be confused with autoflowers — they don’t flower automatically, but their life cycle is significantly shorter compared to traditional photoperiod plants. This hybrid approach gives you the best of both worlds: control and stability + speed.
Comparison: fastflowering vs autoflowering vs photoperiod
| Characteristic | Fastflowering | Autoflowering | Photoperiod |
| Flowering time | 6–7 weeks | 5–6 weeks | 8–11 weeks |
| Light cycle control | Required | Not required | Required |
| Yield | Medium–high | Medium | High |
| THC potential | High (up to 22–25%) | Medium–high (16–22%) | High (20–27%) |
| Resilience | High | Very high | Medium |
| Genetics | Auto + photoperiod hybrid | Ruderalis + sativa/indica | Pure sativa/indica or hybrid |
Fast-flowering strains stand out for their speed and reliability. They offer solid yields, maintain light cycle control, and come close to photoperiod strains in potency and consistency.
Why growers choose fastflowering cannabis seeds
Growers worldwide prefer fast-flowering strains for their versatility, reliability, and performance. Here are the key benefits of these seeds:
- Time-saving: from sprouting to harvest in just 8–9 weeks. This is crucial for short growing seasons or limited grow time.
- Hybrid genetics: combining the resilience of autos with the power of photoperiods.
- Environmental flexibility: suitable for indoor, outdoor, greenhouse, and polytunnel setups.
- Ideal for unstable climates: early harvesting helps avoid issues with rain, cold, and mold.
- High stability: fast strains are well-adapted with consistent phenotypes.
- Powerful effects: THC levels often reach 22–25%, with dense, resinous, and aromatic buds.
- Versatile use: perfect for both recreational and medical applications.
These advantages make fast strains a great choice for beginners who need simplicity and speed, as well as experienced growers looking to optimize their grow cycle and potentially harvest twice per season.
