Grandaddy Purple x Purest Indica – 10 Regular Seeds for $50.00
Flowering Time: 8–9 weeks
Genetics: Grandaddy Purple (Clone Only) x Purest Indica (Steve Murphy Afghan)
Type: Broadleaf-Dominant Hybrid
I’ve always appreciated what Grandaddy Purple brought to Northern Lights #5, but this time, I wanted to go deeper—back to the source. By pairing the famous Grandaddy Purple clone with the Purest Indica (Steve Murphy Afghan) male, the result is a fast-finishing, deeply sedative cultivar with rich color, dense trichomes, and unmistakable old-school funk.
Grandaddy Purple: California’s Royal Purple
Grandaddy Purple, or GDP, is a clone-only cultivar that became iconic in the early 2000s California medical scene. With genetics traced back to Purple Urkle and Big Bud, it’s known for its grape-like aroma, purple hues, and strong body stone. The cut used in this cross is the true GDP, selected for its bag appeal, strong resin output, and therapeutic, calming effects.
Purest Indica: The Steve Murphy Afghan
Purest Indica is the original Steve Murphy Afghan, gifted to Seattle Greg in 1979 and used as a foundational component in early Northern Lights breeding projects. It’s a short, dense, fast-finishing broadleaf variety known for its narcotic effect, tight internodes, and strong Afghan flavor. As a male, it breeds consistently, contributing body, density, and finish time without overpowering the mother.
The Hybrid: Grandaddy Purple x Purest Indica
This cross blends GDP’s sweet, fruity grape terpenes with Purest Indica’s earthy, acrid funk, resulting in a plant with deep purple potential, heavy resin content, and a crushing, full-body effect. Expect compact growth, vibrant coloration, and a terpene profile that spans sweet berry to gassy Afghan. This line is especially suited for hash production, evening use, and pain management.
Ideal for:
-
Growers looking for a fast, heavy-yielding purple strain with old-school potency
-
Breeders wanting to stabilize dense structure and resin traits in purple lines
-
Smokers who appreciate richly colored buds with powerful body effects
