About Jack Herer
Jack Herer is a sativa-leaning strain named after the cannabis activist and author of The Emperor Wears No Clothes. Developed in the Netherlands by Sensi Seeds, it combines Haze with a cross of Northern Lights #5 and Shiva Skunk. You may see it shortened to JH or called The Jack.
The aroma is distinctly piney, with earthy and woody undertones. Pinene is widely associated with that fresh pine scent, terpinolene, its leading terpene, often adds a herbal, slightly floral brightness, and caryophyllene contributes woody spice. Buds are typically light green and frosty, with a slightly airy, sativa-style structure.
Jack Herer is commonly described as energetic, focused and creative, which has made it a long-standing daytime favorite. Many people report a clear-headed feel that pairs well with activities or socializing. THC usually measures between 18% and 23%, with CBD at about 1% or less, though potency varies by grower and batch.
Its moderate-to-high THC makes it a good fit for consumers with some experience, while beginners may prefer a smaller serving. Start low, go slow, and check the lab results printed on the package. Find Jack Herer at licensed dispensaries and delivery services near you on WhereLeaf.
