Grandaddy Purple’s Origins

Grandaddy Purple hasn’t always been the most popular strain on the block. In fact it’s origin story is quite interesting. The gentleman credited with bringing Grandaddy Purple to the mainstream in California is Ken Estes. This is how Mr. Estes describes the evolution of Grandaddy Purple.

Ken Estes the man credited with bringing grandaddy purple to california

During the Vietnam War many veterans returned home with highly potent strains of Marijuana. Among the strains imported into the US were Thai, Buddha and Afghani.

Thai, Buddha and Afghani

The vets knew these strains were very potent and purple, but had low yields. Many in Northern California in the Humboldt area started breeding these purple strains. This created powerful purple hued Indicas. Yet for some reason they never caught on in popularity. Until that one legendary day Ken Estes met up with a Northern California Indian tribe.

Ken had hooked up a few members in the tribe with marijuana in the past, so he was in their good graces. Ken was invited to a ceremony and brought into a circle with prayers and a medicine man. The medicine man presented Estes with a strain of marijuana the Indians had been growing for 22 years. Ken’s jaw dropped when he saw the buds in the light. Covered inside and out in purple and with the sweetest smell imaginable. Ken said “It smelled Purple, I didn’t even know what Purple smelled like.”

Ken nicely asked the Indians if they had more. They gave him some and the rest is history. He brought this mystical Indian strain to California residents and it has been a favorite ever since. Though Ken doesn’t know the exact genetics, he speculates it is a product of multiple crosses. Likely from the original Vietnam vet strains and various skunk strains. Some believe modern GDP is a cross between Purple Urkle and Big Bud,. This cross is favorable for increased yields. Regardless of genetics, it is undeniable Grandaddy Purple is now one of the most popular strains in the world.

Why is GDP Purple?

Grandaddy Purple’s signature purple hue can be attributed to two main factors.

1. Genetics. Buddha and Afghani have a lot of purple in them and the original GDP was likely a result of multiple crosses within these strains.

2. Temperature. To Turn Purple GDP requires very low temperatures around 55 degrees in the end of flowering. This is to simulate GDP’s original harsh environments where winter comes quickly.
