Granddaddy Purple

This indica-dominant hybrid is known by more than five names, but under each one it remains recognizable for its unique character in both cultivation and use. The remarkable Granddaddy Purple, also known as GDP, is one of the best strains of North American origin, with unique genetics that allow for relatively easy cultivation of massive plants with large, fragrant buds of excellent quality. It goes without saying that it's one of the best representatives of indica hybrids with a purple hue, repeatedly awarded in international cups and competitions.

A Glimpse into History and Characteristics

Developed in 2003 by American breeder Ken Estes, Granddaddy Purple is a feminized photoperiod indica-dominant (70/30) strain that harmoniously combines the genetics of Big Bud and Purple Urkle. From its lineage, the strain inherited amazing productivity, a compact structure, charming appearance, potency and a unique flavor and aroma.

Treat this plant with respect and attention, as this "granddaddy" of indica hybrids needs plenty of time to reach full maturity. Outdoors, if sturdy seedlings are planted in the spring, expect to harvest in October at the earliest. Indoors, the flowering stage lasts 9-10 weeks, followed by no less than 500 g/m² (18 oz) of delicious buds with up to 24% THC.

Flavor and Aroma

The GDP's aromatic bouquet is a rich blend of sweet grape with subtle hints of forest berries, pine and spices, highlighted by a dash of black pepper. The flavor mirrors the sweetness of the aroma, enhanced by ripe fruits, subtle skunk undertones and the earthiness typical of indica strains.

Recreational and Medicinal Use

Despite its venerable age, GDP is a powerhouse in terms of its potent effects on the body and mind. Beginners should approach it with due respect, as even experienced stoners can be easily knocked out. You can expect total relaxation that encompasses both the physical and mental realms. In the midst of the overall serenity, a pleasant bonus will be a gentle cerebral buzz, giving a sense of bliss and carefree fun.

With its high THC content, this strain has a diverse terpene profile and moderate CBD and CBG levels, each within 1%. All this contributes to significant relief from chronic pain and inflammation, alleviation of stress, anxiety, PTSD symptoms, normalization of appetite, and elimination of insomnia.

Cultivation

Granddaddy Purple is easy to grow, and its striking appearance will appeal to novice growers and cannabis connoisseurs alike. Around the sixth week of flowering, leaves and buds will begin to show a distinctive purple hue. As they mature and experience the nighttime temperature drop, this color will become dominant. By the way, always check the environmental conditions, as significant deviations from the normal at any stage of the cycle can affect the overall progress. When choosing a pot, give preference to fabric pots or airpots with a capacity of at least 20 liters (5.3 gallons). Fill it with organic soil supplemented with drainage components and mycorrhizae, and maintain a consistent watering and feeding schedule. Use boosters during flowering. All this, along with pH and ppm control, will help prevent overwatering and overfeeding.

When determining the training techniques, KADAMA experts recommend avoiding ScrOG and giving the plant more freedom. However, LST and tying during the vegetative stage will have a significant and positive influence on maximizing yields. As colas mature, branches may need support due to the weight of overly massive and resinous buds. Thousands of tiny trichome crystals, like stardust, look magical against the dark purple hue.
