Jack Herer
Jack Herer
Also known as: JH, The Jack, Premium Jack, Platinum Jack
Overview
Jack Herer is a legendary sativa-dominant hybrid strain named after the renowned cannabis rights activist and author of 'The Emperor Wears No Clothes,' Jack Herer, who passed away in 2010. Originally created by Sensi Seeds in the Netherlands in the mid-1990s, the strain was developed to capture both cerebral elevation and heavy resin production. The true genetics of Jack Herer consist of (Northern Lights #5 x Haze A) x (Skunk #1 x Haze C), though it is commonly described as a three-way cross of Haze, Northern Lights #5, and Shiva Skunk (though this is disputed by breeders). This strain has gained recognition as a medical-grade cannabis variety, distributed by Dutch pharmacies, and has won numerous awards including multiple High Times Cannabis Cup victories.
Jack Herer is a balanced hybrid with approximately 55-60% sativa and 40-45% indica genetics, providing users with the best of both worlds - energizing cerebral effects combined with mild body relaxation. The strain produces dense, resin-covered buds with a sparkling crystalline appearance, featuring bright green hues accented by rusty orange pistils and abundant trichomes that give it a frosty, sticky texture. Jack Herer exhibits a complex aromatic profile with herbal spice, sweet pine, citrus, and woody notes, creating an inviting fragrance that signals its top-shelf quality.

Growing Information
Jack Herer has a flowering period of 8-10 weeks when grown indoors, with some phenotypes flowering as early as 8 weeks. Indoor yields are approximately 600-900 grams per square meter (around 18 ounces per square meter), with some growers achieving 1-1.5 grams per watt of light. Outdoor cultivation can yield 400-600 grams per plant in suitable climates, with harvests typically ready in late September to early October. The strain prefers temperatures between 70-80°F (21-27°C) during the day with slightly cooler nights, and thrives in Mediterranean-like climates. Humidity should be maintained at 60-70% during vegetative growth, reduced to 40-50% during flowering to prevent mold. This strain can grow quite tall and bushy, requiring adequate spacing and branch support, with training techniques like SOG, SCROG, or topping recommended to manage height. Jack Herer is considered moderately challenging to grow, suitable for beginners but requiring some experience to maximize potential.
