Grandaddy Purple is a world-renowned 80/20 indica-dominant hybrid strain that initially hit the California medical marijuana scene in 2003 when Ken Estes, the medicine man himself, cultivated the first sweet and candy-like phenotypes that became Grandaddy Purple. In this Grandaddy Purple review, we cover the strain’s genetics, appearance, aroma and taste, and effects.

Grandaddy Purple Genetics

Grandaddy Purple, sometimes simply called “GDP,” is a cross between the high-yielding Big Bud strain and the herbaceous purple strain known as Purple Urkle. Since it’s early debut in California, Grandaddy Purple has become a global cannabis icon for its compelling medicinal value. GDP tests anywhere from 17-24% THC, making this strain a go-to for chronic pain, insomnia, stress and even a lack of appetite.

Grandaddy Purple Appearance

Next in this Granddaddy Purple review, we take a look at this strain’s appearance. GDP is easily recognizable by her large flowers and vibrant purple coloration. Physically, she takes after her Big Bud parent, though she gets her delicate aromas and flavors from the Purple Urkle parent, making her both beautiful to look at and well-balanced to smell and enjoy. Like most indica-dominant strains, she tends to grow short and stocky with a dense and thick cola structure. 

Her broad water leaves are a deep, nitrogen-rich shade of green, though her stems tend to appear lighter in color. Her flowers are bright sage green with sporadic hints of a deep royal purple that give the plant a unique, almost-alien look. Each flower is covered in a blanket of thick, resinous trichomes and sandy orange-yellow pistils curving through the leaves. Inside a flower, you can see the juicy trichome heads that make the flowers incredibly sweet and sticky. This resin production makes her a popular choice for concentrates.

Grandaddy Purple Grow guide

The Grandaddy Purple strain is rated as moderately difficult to grow for beginners. While her stocky indica growing structure makes her easy to grow and train, she relies on a relative humidity level of around 50%, which can be challenging to maintain in dry places like Colorado. However, she is naturally resistant to most molds, pests, diseases and powdery mildew. She can be grown both indoors and outdoors and takes 8-12 weeks to fully mature and flower. 

Grandaddy Purple Aroma

On the nose, Grandaddy Purple offers notes of citrusy sweetness, though earthy undertones of wood tend to shine through. A more in-depth inhale will bring out bright notes of grape and berry. However, when you grind Grandaddy Purple flowers or break them apart, a pungently fruity, earthy aroma appears to envelop the entire room. Ultimately, the strain smells ‘purple.’ 

Grandaddy Purple Taste

Smoking Grandaddy Purple is a delight for the taste buds. On the initial inhale, you’ll be met with a tart tangy grape and berry flavor. The smoke is on the thicker side and tends to be earthy and peppery thanks to its high levels of relaxing and sedative terpenes like Myrcene and Caryophyllene. The thick smoke is known for making medical patients cough and may cause dry mouth and dry eyes. On the exhale, you’re met with a pleasant aftertaste that is reminiscent of grape-flavored hard candies, like Jolly Ranchers.
