The Flash is an indica-dominant hybrid of the sativa Jack Herer, the indica Super Skunk, and Haze, itself a sativa. It’s best known for the speed of the high, which hits almost instantly, a result of this strain’s Jack Herer genetics. While THC levels are high, CBD levels are something of a mystery: This definitely isn’t recommended as a CBD strain, but the exact percentage of CBD is unknown. The Flash smells of earth and citrus and has a sweet flavour. The high is multi-faceted, with deep body relaxation, euphoria, energy, and creativity, along with a strong happy feeling.
