Karel’s Haze by Super Sativa Seed Club: Old-School Haze Meets Modern OG Genetics
Karel’s Haze by Super Sativa Seed Club is a Sativa-dominant hybrid created by crossing Old School Haze x Chem Dog OG Fire. This distinctive combination brings together traditional Haze genetics from the 1980s with the pungent, fuel-inspired characteristics of modern American varieties.
Named after Karel, one of the key figures behind Super Sativa Seed Club, this release represents an important part of the breeder’s collection.
The original Haze parent contributes classic Sativa heritage, while Chem Dog OG Fire introduces a contrasting genetic influence with deeper, gassier aromatic characteristics.
The result is a variety that combines old-school cannabis history with a more contemporary profile.
For collectors interested in classic Haze genetics and influential American hybrids, kerel’s haze offers an appealing combination of two very different genetic backgrounds.
Tropical Lime, Fresh Citrus and Pungent Gas Aromas
One of the most distinctive features of this variety is its complex aromatic profile.
Super Sativa Seed Club describes tropical lime, fresh citrus, pungent gas and deeper fuel-like undertones, creating a combination that reflects both parent varieties.
The Old School Haze influence introduces a bright, refreshing character, with lime and lemon-inspired notes providing the foundation of its aromatic identity.
Alongside these citrus characteristics, Chem Dog OG Fire contributes a heavier, gassier quality.
The contrast between fresh tropical notes and darker fuel aromas gives the variety a particularly recognisable profile.
The breeder also highlights differences between individual genetic expressions, with some emphasising the fruity characteristics and others displaying stronger gas-inspired aromas.
This variation makes Karel’s Haze by Super Sativa Seed Club especially interesting for collectors exploring the aromatic diversity of traditional Haze and OG genetics.
Unlike many modern hybrids dominated by sweet candy or creamy dessert aromas, this variety offers a sharper combination of citrus and fuel.
What Makes Karel’s Haze Genetics Special?
The most interesting feature of this release is its carefully selected parentage.
Old School Haze represents an important part of cannabis breeding history, with genetics that have influenced numerous modern Sativa varieties.
Chem Dog OG Fire introduces a different genetic background, combining the pungent characteristics associated with the Chemdog and OG families.
Together, these parents create a hybrid that reflects both traditional Dutch breeding heritage and contemporary American influences.
