Why Choose Autoflower Seeds?

• Speed: Seed to harvest in ~8–12 weeks.
• 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).
• Feeding: Start light; autos often need ~10–20% less nutrients than photoperiods.

Autoflower vs Photoperiod: When to Pick Autos

• Pick Autos if you need speed, have limited height, or want a simple light schedule.
• Pick Photoperiods if you prefer full control over veg time, big training projects, or monster yields.

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.
