Meet Granddaddy Purple, the legendary purple cultivar with rich grape-and-berry character, frosty buds, and a deeply soothing finish. With THC potential up to 25%, this feminized favorite brings classic appeal and generous harvest potential to gardens of every experience level.
Our breeders bring together Purple Urkle and Big Bud to create Granddaddy Purple’s celebrated 70% indica, 30% sativa profile. Purple Urkle lends its signature berry sweetness, while Big Bud contributes sturdy growth and impressive flower production. First introduced in 2003, GDP has become a benchmark for purple genetics.
Expect a bold burst of sweet grapes and ripe berries, rounded by a smooth, fruity finish. Dense flowers wear a sparkling coat of resin, giving every harvest striking visual appeal and rich aromatic character.
The experience opens with a gentle wave of euphoria and a happy, talkative mood. Then the indica influence settles in, bringing profound physical relaxation and a calm, unhurried feel. Its lasting potency makes GDP a natural fit for relaxed evenings and well-earned downtime.
Valencene adds a bright citrus-and-berry accent, linalool brings soft floral notes, and camphene grounds the profile with a subtle, earthy edge. Together, these terpenes shape GDP’s unmistakable fruity aroma and mellow character. Many enthusiasts choose this classic for evening relaxation and quiet moments.
These feminized seeds produce female plants, making it easier to focus your grow on flower production. Granddaddy Purple suits indoor and outdoor gardens and is beginner-friendly with attentive care. Grassfarmer guarantees germination, so you can start your grow with confidence.
In early growth, provide a quality, well-draining medium such as coco, peat, or a suitable soil blend. Keep moisture balanced and feed a steady, appropriate nutrient schedule as plants develop. Indoors, ScrOG training can help create an even canopy and improve light access to lower growth.
GDP grows into a compact, sturdy plant, reaching around 4.92 ft (1.5 m) under suitable conditions. Strong branches support its dense, resin-rich flowers. Maintain good airflow, watch for pests, and manage humidity carefully as flowering progresses to help protect those heavy buds.
Allow 8–10 weeks of flowering before harvest. Indoor growers can expect around 1.47–1.64 oz/ft² (450–500 g/m²), while outdoor plants can produce approximately 21.16–24.69 oz (600–700 g) per plant in favorable conditions. Outdoor harvest typically arrives in October, with cool nights helping bring out the signature purple hues.
