Granddaddy Purple (Royal Queen Seeds)

Experience the Royal Deep Relaxation of Granddaddy Purple

Granddaddy Purple, often abbreviated as GDP, is an absolute legend of the West Coast scene that originated in 2003. This prestigious indica-dominant cultivar is the result of a masterful cross between Purple Urkle and Big Bud. With a genetic profile of 75% indica and 25% sativa, you’re bringing home a powerful classic renowned for its majestic purple appearance and impressive lineage.

Aroma & Effect

As soon as you open the jar, you’re greeted by a complex and enticing bouquet of sweet blueberries, ripe grapes, and a hint of candy. Beneath these fruity top notes lies a refreshing hint of pine, providing a refined sensory experience. The effect is exactly what you’d expect from a high-quality indica: a potent, physically relaxing stone accompanied by a happy, euphoric vibe. It’s the ultimate choice for an evening of pure relaxation and mental satisfaction after a busy day.

Growing Characteristics & Yield

Cultivating Granddaddy Purple is a true joy for both novice and experienced enthusiasts, thanks to its robust and low-maintenance nature. Indoors, the plants reach a manageable height of 80-120 cm, while outdoors under the sun, they can grow up to 150 cm. After an average flowering time of 8 to 10 weeks, you can expect a generous harvest of compact, resinous buds, with yields reaching up to 500g/m² indoors and up to 600g per plant outdoors by early October.

Grow Tips

To really make those iconic, deep purple colors that Granddaddy Purple is famous for pop, I recommend carefully lowering the night temperature during the final phase of flowering. Because the buds of this cultivar can become extremely compact and heavy, it’s essential to monitor humidity closely and provide extra support to the branches around day 60. Good air circulation through the canopy ensures this 'Granddaddy' stays in top condition until harvest.
