History and Genetics of Granddaddy Purple

Granddaddy Purple was commercialised by Ken Estes, who describes himself as a "father, philanthropist, and entrepreneur". While there are many different accounts of the origins and exact genetics of GDP, Ken has gone "on the record" in several interviews, saying that his Purple is the offspring of Afghani, Buddha, and Thai strains that were brought back to the US by Vietnam War veterans.

Kept alive by veterans, growers, and breeders in Humboldt County, Ken believes that these original Asian genetics eventually got crossed with the Acapulco/Colombian Gold and Panama Red sativa varieties that were popular in the US at the time, creating the legendary Skunk. Ken claims that his unique cut of Purple is actually a Skunk offspring that was given to him by a community of Native Americans he befriended while living in Humboldt County, who had preserved the strain for 22 years before sharing it with him.

To this day, GDP is one of the most popular varieties at dispensaries and cannabis collectives, where it is sought out by recreational users and holistic users alike.

Besides being popular among recreational users, Granddaddy Purple is also very popular among holistic cannabis users seeking to address physical and mental tension, as well as appetite loss.

Like all high-THC cannabis strains, Granddaddy Purple is capable of producing some unwanted side effects. These include:

  • Dry eyes and dry mouth
  • Dizziness

Note that GDP has very strong physical effects. Many users report feeling couch-locked or lethargic after using this strain, so keep that in mind before trying Granddaddy Purple for yourself. Many users recommend using GDP at night, or when you have a free schedule so you can freely enjoy its intense physical stone.

Cultivation — How Easy Is Granddaddy Purple to Grow?

There is mixed information available regarding the grow traits of Granddaddy Purple. Ken Estes has said that the strain likes cold, dry temperatures, likely due to its indica dominance. Ken has also said that GDP doesn't produce the biggest yields, as his plants tend to stay short and compact, with dense bushy growth and few branches. Like all dense indica strains, Granddaddy Purple doesn't like high humidity, as this can attract pests and pathogens to make their home among its thick leaves and flowers.

Some tips to help you grow Granddaddy Purple at home include:

  • Keep temperatures cool, especially during the late flowering stage
  • Keep plenty of cool air moving around your tent/garden
