Jack Herer doesn’t need an introduction. It’s the strain that is the introduction. If someone’s getting serious about growing, it’s only a matter of time before this legendary hybrid ends up on their radar. Named after the iconic cannabis activist and author, Jack Herer is more than just a nod to a pioneer. It’s a potent, perfectly balanced sativa-leaning strain that’s earned its place in the cannabis hall of fame, and then some.
With a reputation built on uplifting effects, razor-sharp focus, and a smooth citrus-haze profile, Jack Herer has long been a go-to for creative sessions, social moments, or just dialing into the day with a clear head. But this isn't just about the smoke. Growers love her for her stability, vigor, and ability to deliver chunky, crystal-laced buds in solid amounts, whether indoors or out. A little finicky during flower, maybe. But give her the care she deserves and she’ll show you exactly why she’s stood the test of time.

Jack Herer is the result of some of the most precise and thoughtful breeding work in cannabis history. She’s a three-way cross between Haze, Northern Lights #5, and Shiva Skunk, each a heavy-hitter in its own right. This blend marries the spicy cerebral fire of classic Haze with the robust structure and resin production of NL#5, and the raw potency of Shiva Skunk. Originally developed in the Netherlands, Jack was designed to hit medical-grade quality. And it shows. She quickly became a staple in Dutch pharmacies before going global.
She’s not just popular. She’s legendary, with a long list of cannabis cup wins and more than a few modern strains tracing back to her lineage.
Jack Herer Fem brings the kind of high that creeps in with a grin and sticks around with purpose. Expect a fast onset of mental clarity, uplifting energy, and just the right touch of body calm to keep things grounded. It’s not overwhelming, but it’s definitely not mild either. Great for brainstorming, working on a project, or firing up a conversation with friends.
flavour-wise, she leans classic. A bright citrus punch over a background of hazy spice. There’s something almost electric about the inhale, like peeling a fresh lemon over incense, and the finish has that earthy warmth that stays with you.
Jack Herer clocks in with 20% THC and a gentle 0.8% CBD, which makes her plenty potent without tipping into the overwhelming side. She’s functional, but not forgettable.
Jack’s terp profile is a layered one, led by terpinolene, alpha-pinene, and limonene, giving it that signature zesty, herbal, and piney haze aroma. You’ll also find nerolidol, eugenol, and a touch of gamma terpinene in the mix. Altogether, it delivers a complex scent with fresh citrus highs, a peppery tickle, and a subtle woody undertone.
This terp blend doesn’t just smell amazing. It plays a big role in the alert-but-calm effect that makes Jack such a great daytime strain.
This one’s not for absolute beginners. Jack Herer Fem tends to stretch, and while she’s stable and well-bred, she does ask for attention in flower. If you’ve already grown a few plants and feel comfortable with training techniques and dialing in your environment, you’ll be just fine. She rewards attentive growers with top-tier resin production and a finish that’s every bit worth the effort.
Jack adapts well to both indoor and outdoor setups, as long as she’s given the right conditions. Indoors, her height stays manageable with some topping or low-stress training. Outdoors, especially in Mediterranean or arid climates, she’ll happily take up space and stretch taller, delivering a strong, healthy structure with plenty of airflow through her branches.
She also handles greenhouses nicely, especially if you’re somewhere with fluctuating temps and need a bit more control. Just keep an eye on humidity in flower. Her dense colas can get sticky fast.
Expect a flowering time of 60 to 70 days, with indoor yields around 500 to 600 gram per m2. Outdoors, you’re looking at 600 to 700 gram per plant, depending on climate and how much love you give her.
She grows to 90 cm to 130 cm indoors and can reach up to 130 cm to 180 cm outdoors, especially if left to stretch under the sun. Buds are frosty, firm, and come with that classic sativa crown structure. Long, spear-like, and absolutely drenched in trichomes by the final weeks.
Ready to grow a true classic? Jack Herer isn’t just a strain. It’s a rite of passage. Whether you’re after iconic flavour, sharp mental clarity, or a grow that teaches you a thing or two along the way, she delivers.

A really great example of Jack Herer. My phenos grew more leaning to the sativa heritage topping out at 1.8m indoors and that was after super cropping in week 2 of flower. She takes everything in her stride and would be a good choice for anyone who has the vertical space. Worth bearing in mind if you plan on doing mixed strains. The smell off the bud is insane. It gets to the back of your throat and makes your mouth water. High is for me a great zone out buzz when I need focus. Maybe too much focus😋. Simple to grow with no signs of stress or disease which is credit to weedseedsexpress for breeding such strong genetics
2 found this usefulThe seed genetics are phenomenal! All of the seeds that I started germinated and all of the plant matured to about 6 feet covered with massive buds. This was an outdoor grow. Considering such a high yield per plant, it is a must to train/stabilize these plants. Especially when you are in an area of high wind. I could not ask for such great service, support, shipping and superior genetics from this company! Look no more! You have found the best! Thanks WSE
