Jack Herer is a sativa-dominant cannabis strain that has gained as much renown as its namesake, the marijuana activist and author of The Emperor Wears No Clothes. Combining a Haze hybrid with a Northern Lights #5 and Shiva Skunk cross, Sensi Seeds created Jack Herer hoping to capture both cerebral elevation and heavy resin production. However, consumers typically describe this 55% sativa hybrid as blissful, clear-headed, and creative.
