Autoflower Cannabis Seeds: Fast, Easy Harvests for Any Grow Space
Everything you need to know about autos — timelines, light cycles, yields, training, and our top picks.
Why Choose Autoflower Seeds?

- Simple light: 18–24 hours of light from start to finish — no 12/12 flip required.
- Compact: Great for small tents, closets, or balconies.
- Beginner-friendly: Short lifecycle = fewer chances to make big mistakes.
Quick Specs & Best Practices
- Light schedule: 18/6 or 20/4 (many keep 24/0 for simplicity).
- Temps: 20–26 °C (68–78 °F); RH: 45–60% (lower late flower).
- Pot sizes: 3–5 gal (11–19 L). Plant in the final pot to avoid transplant shock.
- Training: Favor LST; avoid heavy topping late (autos don’t have time to recover).

Autoflower Grow Notes (Stage by Stage)
- Week 1–2 (seedling): gentle light, high RH (65–75%), minimal feeding.
- Week 3–4 (early veg/early flower): begin LST; keep EC/ppm modest.
- Week 5–8+ (flower): lower RH to 40–50%; increase P/K; support colas.
Autoflower FAQs
Do autoflowers yield less than photoperiods?
Often slightly less because veg time is fixed, but modern autos can rival photoperiods in small spaces when trained well and kept under strong LED lighting.
Can I top an autoflower?
Early topping is possible but risky; low-stress training is safer. If topping, do it once around day 18–21 and allow recovery.
What light cycle is best for autos?
18/6 or 20/4 are the sweet spots for growth and efficiency. Some growers run 24/0; it works but offers no dark-period metabolism.
