Granddaddy Purple is a classic indica variety that traces its genetic lineage to the crossbreeding of Afghani and Northern Lights. This strain is cultivated in indoor environments.
The chemical profile of Granddaddy Purple is defined by a complex terpene structure, led by primary caryophyllene, followed by linalool, myrcene, humulene, bisabolol, pinene, caryophyllene-oxide, ocimene, beta-pinene, nerolidol, limonene, and borneol. These compounds create a distinct sensory experience, blending earthy and floral notes that reflect the intricate terpene arrangement.
As a THC-dominant cultivar with 18.8% THC, Granddaddy Purple is recognized for inducing feelings of relaxed, happy, and sleepy states. It is primarily utilized by those seeking relief from stress, pain, or sleep-related difficulties. The strain’s influence on the broader cannabis market is evident through its list of offspring, which includes Cherry Pie, Apples and Bananas, Frostberry, Purple Punch, GDP Special, Granddad's Lavender, Granddaddy Purple X Chocolate Trip, and Granddads Blue Cheese.

Russo 2011: only terpene that is a selective full CB2 agonist (100 nM); Gertsch et al. 2008: acts as dietary cannabinoid; unique anti-inflammatory and gastric cytoprotective properties.
Russo 2011: local anesthetic equal to procaine; anticonvulsant via glutamate/GABA modulation; reduces morphine tolerance via multisite opioid/GABAergic/cannabinoid action.
Russo 2011: naloxone-sensitive analgesia, potentiates barbiturate sleep; dominant sedating terpenoid; blocks hepatic carcinogenesis by aflatoxin.

★★★★★too much couch lock for mid day
17 Jun 2026This stuff is super potent. I smoked a little too much mid-day and ended up glued to the couch, totally useless for my errands. Might be good for insomnia but kinda wrecked my afternoon productivity.
★★★★★my anxiety meds but delicious grapes
15 May 2026My go-to for winding down after a long day. One hit from the bowl and I'm floating, all the stress just melts away. Total bliss for my racing thoughts.
