Description

The Original 2005 Grand Daddy x Klar Cannabis Seeds 

This hybrid brings together two legendary strains: GrandDaddy Purp (GDP) and Klar, a rare IBL (inbred line) bred by Hash Bean as part of Denmark’s G13 Project. The result is a potent, resin-packed indica hybrid with incredible strength, deep flavors, and breeding potential.

GrandDaddy Purp (GDP) is a 75% indica / 25% sativa hybrid, created from Purple Urkle (Mendocino Purps phenotype) and Big Bud (Afghan x Skunk lineage). Known for its deep purple hues, grape-like aroma, and deeply sedative effects, it has been a staple in cannabis breeding for decades.

Klar was created by Hash Bean in the early 2000s as part of Denmark’s G13 Project, undergoing 17+ generations of inbreeding (IBL) to achieve absolute stability. The result is a strain that is exceptionally uniform, producing completely consistent plants with insane resin production and extreme potency. Its strength makes it perfect for extractions and breeding projects, delivering pure knockout effects. The aroma is intensely unique, described as burnt differential fluid mixed with burnt transmission fluid and rubber—a true old-school hash strain.

This GrandDaddy Purp x Klar cross delivers exceptional potency, high resin production, and robust indica effects. Its terpene profile is dominated by myrcene, caryophyllene, and humulene, producing a complex mix of fruity, earthy, and industrial fuel-like aromas. The effects are deeply relaxing, sedating, and ideal for pain relief, insomnia, and high-tolerance users.

With THC levels exceeding 25%, this strain is not for beginners but is a dream for extract artists and breeders looking to add raw power to their projects. It thrives indoors, outdoors, and in greenhouses, producing dense, resin-soaked buds with extreme trichome coverage.
