Here’s a clear comparison to help you understand the difference between fast version seeds and Autoflower Seeds in cannabis cultivation:
🌱 1. What Are They?
Fast Version Seeds
- Traditional photoperiod cannabis seeds that have been bred to grow faster than regular photoperiod strains.
- They still depend on light cycle changes (more darkness) to trigger flowering, but overall they finish quicker than standard photoperiod plants.
Autoflower Seeds
- Cannabis seeds that automatically switch from vegetative growth to flowering based on age — not light cycles.
- They’re usually derived from Ruderalis genetics and are known for speed and simplicity.
⚡ 2. Growth & Flowering Timeline
| Type | Starts Flowering When… | Typical Grow Cycle |
|---|---|---|
| Fast Version Seeds | Light schedule change (e.g., 12h light / 12h dark) | Generally shorter than normal photoperiod, but longer than autos |
| Autoflower Seeds | Maturity (age) | Very fast (often 8–10 weeks total) |
- Fast Versions: Faster than standard plants but still depend on a light switch to flower.
- Autoflowers: Flower automatically around a certain age — no light schedule change needed.
🌞 3. Light Schedule
Fast Version Seeds
- Need controlled light cycles.
- Usually started at long light (18–24h) then switched to 12/12 to flower.
Autoflower Seeds
- Can be kept under long light hours throughout (e.g., 18–20h) — no switching needed.
- Great for beginners or simple setups.
📏 4. Size & Yield
Fast Version Seeds
- Tend to grow larger than autos.
- Usually higher potential yields (more biomass).
Autoflower Seeds
- Often smaller plants, lower yields per plant.
- But you can grow multiple cycles per year.
🧬 5. Control & Flexibility
- Fast Version: Offers more control over plant size and flowering timing.
- Autoflower: Very low maintenance — simple but less flexible.
💪 6. Which Is Better for You?
Choose Fast Version Seeds if:
✔ You want larger plants
✔ You don’t mind managing light schedules
✔ You want higher yields
Choose Autoflower Seeds if:
✔ You’re a beginner
✔ You want the easiest grow
✔ You want faster cycles with minimal care
🧠 Summary
- Fast Version Seeds = Photoperiod plants bred for faster flowering, but require light changes.
- Autoflower Seeds = Auto-flowering regardless of light, super fast and easy to grow.
