Granddaddy Purple Strain Overview

The grandfather of cannabis strains is here. You guessed it – Granddaddy Purple. “Grandaddy Purp,” “GDP,” or “Ken’s GDP” started rising to fame in 2003, when successful breeder Ken Estes first grew the tasty cultivar in the Bay Area of California. Merging the genetics of Afghani, Buddha, and Thai cultivars brought back from Vietnam, this potently perfumed strain delivers a wallop of cerebral euphoria that will leave you feeling alert yet relaxed. It gets its name from the tiny purple hairs that curl around the thickly frosted buds. These purple hairs may be minuscule, but they possess a mighty power 


Inhale the fruity essence of Grandaddy Purple for a sweet blend of berries and grapes infused with earthy and skunky undertones. Thanks to GDP’s robust genetic lineage, this strain is perfect for medical and recreational consumers alike. Sprinkle a little into your roll-up before bedtime to catch some undisturbed Z’s, or dabble in this iconic strain for an appetite boost.

Granddaddy Purple Strain Effects & Common Usage

High THC levels may encourage the release of adenosine an important sleep neurotransmitter to promote a healthy night’s rest. 

Euphoria. Limonene has been demonstrated to have mood-boosting and anxiety-relieving properties. 

Sedating. THC and myrcene may produce sedative effects when consumed at high levels. 

Physical relaxation. Caryophyllene is a terpene with anti-inflammatory and analgesic properties, which may help relieve muscle pain and inflammation. 

Anxiety/panic disorders.  Studies show that linalool has natural anxiolytic properties that limonene may prevent the proliferation of a stress hormone called cortisol. 

Pain relief.  Granddaddy Purple’s analgesic properties can be attributed to the high THC and blend of terpenes like linalool, pinene, caryophyllene, myrcene, and limonene. This profile makes it a solid choice for many patients hoping to alleviate chronic pain caused by conditions like arthritis, fibromyalgia, and neuropathic pain. 

Increase appetite.  Appetite-boosting cannabinoids like THC and terpenes contained in the Grandaddy Purple strain, such as linalool, may appeal to patients with eating disorders or cachexia.
