Sensi Seeds developed the sativa-dominant hybrid Jack Flash by combining the famous strains Jack Herer, Haze, and Super Skunk together into an energetic and buzzy hybrid.
Jack Flash is enjoyed by sativa lovers for the intensely energetic head high this strain produces, giving its patient an uplifted head effect and a mellow body buzz.
Jack Flash's gorgeous flowers are a light green color, brightened by the chunky gem-like trichomes that lay along the surface of the bud, alongside amber-colored pistils that twist between calyxes.
This strain's flowers produce a pungent, earthy aroma, that becomes sweet and citrusy when this strain is vaporized or smoked.
