How to Grow Granddaddy Purple Autoflower Seeds

Growing GranddaddyPurple Autoflower seeds is straightforward and rewarding. The plant’s autoflower trait means it does not rely on changing light cycles to flower, making cultivation simpler.

  • Light: Use a full-spectrum LED light for indoor grows, aiming for 18 hours of light and 6 hours of darkness daily.
  • Feeding: Start with half-strength nutrients, increasing slightly during the vegetative phase, then switch to a bloom-specific formula rich in phosphorus and potassium during flowering.
  • Training: Low-stress training (LST) is recommended to maximize light penetration and yields, but avoid high-stress techniques as autos have a shorter life cycle.
  • Pest and Mold Prevention: Keep humidity levels moderate, especially during flowering, to prevent mold growth. Ensure good airflow indoors and monitor plants regularly.
  • Harvest Time: Expect to harvest in about 8–10 weeks from seed, with yields reaching up to 300g/m² under optimal conditions.

Indoor vs Outdoor Growing

Granddaddy Purple Autoflower adapts well to both indoor and outdoor environments.

Indoor: Its compact height (60-100 cm) makes it ideal for small spaces, tents, or discreet setups. The controlled environment helps prevent pests and mold while allowing you to optimize light and nutrients.


Outdoor: Thrives in warm, sunny climates with good airflow. Outdoor plants develop their signature purple hues under cooler nighttime temperatures. Position plants where they can receive full sun and be mindful of humidity to avoid mold.
