Black Jack

Black Jack is described by Leafly as a Sweet Seeds hybrid of Black Domina and Jack Herer. The reported cross is retained as family context without implying fixed terpene or cannabinoid concentrations across samples.

OGKB

OGKB expands to OG Kush Breath, but Leafly describes its family connection as a believed descent from GSC. The name alone is not used to add OG Kush as a direct parent. An ancestry link preserves the tentative scope of the source account.

Trainwreck

Trainwreck is associated by Leafly with Northern California and Mexican, Thai and Afghan ancestry. The source offers more than one story for its name rather than a single documented origin. Its summary classifies it as hybrid, while the narrative uses sativa language; these labels should not settle pedigree. Pine, earthy and woody are displayed reader tags, separate from a terpinolene-led catalog profile. The ancestry remains broader than an authenticated pair of immediate parents.

UK Cheese

UK Cheese is described by Leafly as a Skunk 1 phenotype associated with the Exodus collective. This page identifies that selection separately from the broader Cheese entry, whose source discusses later family contributions. Shared Cheese names should not erase differences between a clone and later seed lines.
