Growing Big Jack Widow Auto

Big Jack Widow 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 400-500g/m2. Plants typically reach 60-100cm indoors.
