THC: 0.7% | THCA: 18.84% -- Galactic Jack is a name given to two similar, extremely potent (THC 16-26%), energetic and functional, 70/30, Sativa-Dominant, afternoon/evening hybrid pairings. Both strains have the aroma and flavor of lemons, grapefruit and skunk, but while one is a cross between Alien Dog and Sour Jack, the other is a union of Jack Herer and Space Queen. Buyer be wise and aware.
