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 the cerebral elevation associated with sativas and the heavy resin production of indicas. Its rich genetic background gives rise to several different variations of Jack Herer, each phenotype bearing its own unique features and effects. However, consumers typically describe this 55% sativa hybrid as blissful, clear-headed, and creative. Everest Extracts has a wide variety of cannabis concentrates available for patients. Concentrates are a very popular derivative of cannabis purified to remove excess plant matter and leave a strong concentration of THC. Concentrated cannabis comes in an ever-growing number of different forms from wax to shatter to distillate cartridges.
