Known by various names such as "JH," "Premium Jack," and "Platinum Jack," or simply "The Jack," Jack Herer has gained fame equal to the person it was named after – the cannabis activist and author of the book The Emperor Wears No Clothes. If you’re a cannabis enthusiast, chances are that you’ve come across this popular strain before. However, do you know what exactly sets it apart from other strains? Read on to find out!

Origins and History

The Jack Herer marijuana strain has a fascinating history dating back to the mid-1990s. Sensi Seeds developed this Sativa-dominant hybrid to pay tribute to Jack's unwavering efforts in pushing for the legalization of marijuana. Since then, the strain has garnered numerous awards for its exceptional quality and potency. In fact, it was even distributed by Dutch pharmacies as a recognized medical-grade strain.

Said to be bred based on Haze, Northern Lights #5, and Shiva Skunk, Jack Herer’s lineage can be traced back to authentic strains from various regions around the globe. Haze, a popular Sativa strain known for its energizing effects, originates from Thailand, Colombia, Mexico, and South India. Northern Lights #5, on the other hand, is a potent Indica strain that comes from an Afghani lineage and is known for its relaxing properties. Last but not least, Shiva Skunk is an Indica-dominant hybrid created by crossing Northern Lights #5 with the original Skunk #1, so it offers a sweet mix of cerebral stimulation and physical relaxation.

JH was so popular that it passed down its genetics and part of its name to other hybrid strains such as Jack the Ripper, Jack's Cleaner, and Jack Skellington.

THC and CBD Levels

According to the cannabis lab Analytical 360, the THC percentage in Jack Herer buds ranges from 15% to 24%, while its CBD content is approximately 0.7%-1.0%. This high THC content contributes to its potent effects and popularity among recreational users. However, while it may provide relief from certain symptoms, JH might not offer the same therapeutic benefits as strains with higher CBD concentrations.

Effects of Jack Herer

The strain contains about 50-60% Sativa and 40-50% Indica genetics, which offers a well-balanced experience that provides both cerebral and physical effects, typically leaving users feeling energized but still in complete control of their actions. This strain acts swiftly and promotes imagination, so it's no surprise that it's a favored choice among individuals seeking boosts in productivity or creativity. Numerous users also notice that they become chattier and more engaged in conversations while using this strain, which makes it desirable for those who struggle with social anxiety or aim to spice up their social gatherings. Its uplifting effect also makes it a popular daytime strain and a great option for social events where enhanced focus and communication are desired.

While Jack Herer offers many advantages, you should also keep its potential negative impact in mind. Common side effects some users report are dry mouth and dry eyes. In case you face these problems, we recommend staying hydrated before, during, and after consuming this strain and using eye drops. Occasionally, users may also encounter a feeling of anxiety or paranoia. To avoid this, start with low doses and increase them gradually until you find your optimal level.

Taste and Terpene Profile

When cured properly, JH’s flowers emit a deep floral scent with subtle notes of orange and lemon zest. Breaking open the dense buds, you smell a stronger citrus aroma accompanied by a hint of pepperiness. Once lit, the flowers produce a pleasantly clean and herbal fragrance similar to sage. The smoke itself is smooth and easy, with a taste that resembles herbal flavors. Although not overpoweringly strong, Jack Herer leaves a lingering spicy-floral smell, reminiscent of potpourri.

Medical Uses

According to feedback from users, Jack Herer has the potential to alleviate stress, depression, and social anxiety. Due to its invigorating characteristics, it is most effective when consumed in the morning but usually isn’t recommended for treating insomnia. The ability of cannabinoids to regulate the transmission of serotonin can assist in reducing the occurrence and severity of headaches and migraines. Additionally, the stress-reducing terpenes found in cannabis may also provide relief from tension headaches.

Although Jack Herer holds great promise in terms of its medicinal advantages, you should also consider its potential drawbacks. Just like with any other type of cannabis strain, individual experiences may differ due to factors such as tolerance, consumption techniques, and personal body composition.

Jack Herer Weed Strain Growing Tips

Jack Herer plants can be cultivated both indoors and out. When grown outdoors, it thrives best in a Mediterranean-like climate. It has a high resistance to diseases, mold, and pests, although it's crucial to feed it lightly with essential nutrients to avoid burning. Silica-based fertilizers are the best choice, as they enable the plant to develop large, strong stems that can support the weight of its substantial and compact buds. The plant thieves when grown in a temperature range of 21 to 27 degrees Celsius (70-80 degrees Fahrenheit).

The plants can reach towering heights of up to 2 meters (6.5 feet), which is taller than most other cannabis strains. This means that if grown indoors, they may need to be pruned or topped. Topping involves trimming the top of the main stem to prevent excessive height growth and instead encourage the growth of lateral branches. This results in a shorter and bushier plant.

Flowering and Harvesting Timeline

When cultivated indoors, the Jack Herer strain typically takes around eight to ten weeks to reach the flowering stage. If grown outdoors, expect it to flower between late September and early October.


In terms of yields, growers can anticipate up to 800 grams per square meter (2.62 oz. per square foot) when cultivating this strain indoors, and up to 1,200 grams (42.32 oz.) per plant when it’s grown outdoors.
