A Classic Purple Heritage in Autoflower Form

Granddaddy Purple Auto is a robust, mostly Indica autoflower designed for growers seeking dependable results and a manageable growth cycle. This hardy strain offers a fast turnaround from seed to harvest, making it an excellent choice for both indoor enthusiasts and outdoor cultivators.

Lineage and Genetics

The genetic blueprint of Granddaddy Purple Auto combines the berry-rich Indica personality of Purple Urkel with the high production potential and sturdy structure of Big Bud. These parents are fused with Ruderalis genetics to provide its automatic flowering behavior. The result is a compact plant that maintains the signature mellow character of its ancestors while offering practical garden manners.

The terpene profile is defined by a sweet, berry-forward palette. Growers can expect a complex blend of:

• Sweet caramel grapes
• Mixed berries
• Floral undertones
• Herbal notes that provide a balanced, dry finish

Expected Effects

This strain provides a focused sense of calm that maintains mental clarity while ushering in a happy, bright mood. As the Indica dominance takes hold, a gentle relaxation settles through the body. It is designed for a smooth, non-chaotic experience, making it ideal for evening unwinding or finding a peaceful headspace after a long day.

Cultivation and Yield

Granddaddy Purple Auto completes its life cycle in 56-70 days (8-10 weeks). It reaches a manageable height of approximately 3.9ft (120cm), making it suitable for indoor spaces where vertical room is limited. It thrives in Mediterranean-style conditions, preferring temperatures between 70-85°F (21-29°C).

Yields are impressive for an autoflower, producing between 400-550g/m² indoors and roughly 300g per plant in optimal outdoor conditions. To maximize results, indoor growers should utilize 18/6 or 20/4 lighting schedules, maintain a relative humidity of 55-60% during the vegetative stage, and ensure steady airflow as resin production peaks in the final weeks.
