Growing Galactic Jack Auto

Galactic Jack Auto is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 300g/m2. Plants typically reach 100-160cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Galactic Jack Auto features a citrus, skunky, sweet terpene profile that develops complexity throughout the flowering cycle.

The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.
