What is the Jack Herer strain?
Jack Herer is a sativa-dominant hybrid made by crossing a Haze with a Northern Lights #5 × Shiva Skunk hybrid. Sensi Seeds developed it in the Netherlands in the mid-1990s, and Leafly says it was later distributed by Dutch pharmacies. Sensi Seeds’ founder, Ben Dronkers, calls it his all-time favourite strain.
The Haze side gives it the spicy, uplifting sativa character, while Northern Lights and Shiva Skunk add yield, resin and a steadier body. Leafly notes four phenotypes, three sativa-leaning and one more indica-like, which explains why reports of the same strain can differ. Leafly also lists Amnesia and Cinderella 99 among its offspring.
Who was Jack Herer?
The strain is named after Jack Herer (1939–2010), the American activist who wrote The Emperor Wears No Clothes, a book on the history of hemp first self-published in 1985. He died on 15 April 2010 from complications of a heart attack he had the previous September. Sensi Seeds named the strain in his honour, and it is often sold under nicknames such as JH, The Jack, Premium Jack and Platinum Jack.
Is Jack Herer a sativa or indica?
Jack Herer is a sativa-dominant hybrid. The sources agree on the direction but not on the ratio:
| Source | Type | Genetics | THC | Rating |
|---|---|---|---|---|
| Sensi Seeds (breeder, feminized seed) | 50% sativa, 50% indica | Not stated on the seed page | Not stated (“huge levels of resin and THC”) | n/a |
| Leafly | Sativa-dominant, about 55% sativa | Haze × Northern Lights #5 × Shiva Skunk | 18%, CBG 1% | 4.4 from 5,160 ratings |
| AllBud | 80% sativa, 20% indica | Haze × (Northern Lights #5 × Shiva Skunk) | 15% to 24% | 4.6 from 199 votes |
Sensi Seeds says flowering takes 10 to 12 weeks depending on phenotype, with strongly indica plants finishing in about 8, which matches the spread of reported effects. Our sativa strains guide covers other daytime picks.
How strong is Jack Herer?
Jack Herer is a mid-to-high THC strain: Leafly lists 18% and AllBud a range of 15% to 24%. Google’s AI Overview quotes 18% to 24%. Sensi Seeds gives no percentage but calls the plant ultra-potent and very resinous.
Those figures are for the flower. The Jack Herer products most shops sell, including ours, are distillate: refined THC oil with flavouring that matches the strain profile. Distillate is far more concentrated than flower, so a small puff or a rice-grain-sized dab goes a long way. Canada’s Lower-Risk Cannabis Use Guidelines recommend starting with a small amount and waiting before taking more.
What does Jack Herer taste and smell like?
Jack Herer tastes of pine and wood with a citrus edge. Leafly’s top flavours are pine, woody and earthy. AllBud lists citrus, lemon, orange, sour and sweet, with aromas of citrus, earth, herbs, lemon, pine and wood, and says the smell has been compared to Pine-Sol.
The terpenes explain it. Leafly lists terpinolene first, then caryophyllene and pinene. Terpinolene is less common than myrcene or limonene and gives a fresh, herbal-fruity note; pinene is the pine-needle smell; caryophyllene adds a peppery finish. Our terpenes guide goes through each one.
What are the effects of Jack Herer?
Jack Herer is mostly reported as a clear-headed, energetic daytime strain. Leafly’s most reported effects are focused, energetic and creative, and AllBud lists creative, euphoria, focus, sociable and uplifting. The usual description is an upbeat head high without heavy sedation.
The most reported negatives on Leafly are dry mouth, feeling anxious and dry eyes. Racy sativas can feel too stimulating for some people, so if you prefer a calm evening, an indica-leaning strain is a better fit. This describes what consumers report, not a health claim.
Which Jack Herer products does Bud Cargo stock?
Bud Cargo stocks Jack Herer in three oil formats, all in stock as of 21 October 2026. We do not have Jack Herer flower right now.
| Product | Format | Size | Price | Best for |
|---|---|---|---|---|
| Boost THC Vape Cartridge, Jack Herer | 510 vape cartridge | 1 g | $25.50 | Vaping with a 510 battery you already own |
| Boost THC Distillate Glass Syringe, Jack Herer | Distillate syringe | 1,000 mg | $21 | Dabbing, topping a bowl or joint, refilling |
| So High Distillate Syringe, Jack Herer | Distillate syringe | 1 mL | $30 | The same uses, from the So High brand |
The cartridge needs a 510-thread battery; if a cart stops working, our cart not hitting guide walks through the usual fixes. The two syringes hold the same kind of oil without hardware, so they are the cheapest way to get the Jack Herer flavour. Our Boost brand guide covers the rest of that range, and the distillate menu lists every syringe in stock.
What is the closest flower to Jack Herer?
The closest flower we stock is from the Haze family, Jack Herer’s dominant parent. The Lemon Haze ounce is $55 and the Mango Haze ounce is $62; both share the bright, citrusy sativa character, though neither has Jack Herer’s pine-forward terpinolene profile. Our Lemon Haze strain guide compares it with Super Lemon Haze. Everything else sativa-leaning is on the sativa menu.
