Jack Flash is a cannabis hybrid originally bred by Sensi Seeds, with genetics of Jack Herer, Haze and Super Skunk. This strain produces plentiful, large buds with an earthy, citrusy aroma and flavor. Orange pistillate hairs and frosty trichome crystals are evident throughout. Jack Flash gets its name for its fast-acting effects, which include energizing euphoria and pain relief. Due to its prevalent sativa characteristics, Jack Flash is recommended for morning and daytime use.
