Jack Herer is a sativa-dominant cannabis strain that has gained as much renown as its namesake, the marijuana activist Jack Herer. Combining a Haze hybrid with a Northern Lights #5 and Shiva Skunk cross, Sensi Seeds created Jack Herer hoping to capture both the cerebral elevation associated with sativas and the heavy resin production of indicas. Consumers typically describe this 55% sativa hybrid as blissful, clear-headed, and creative.
