About Jack Herer

History & Genetics

Jack Herer is a strain named after a lifelong cannabis activist whose 1985 book The Emperor Wears No Clothes continues to be an influential resource in the fight for cannabis decriminalization and legalization. A sativa-dominant hybrid developed by Sensi Seeds in the 1980s or 90s, it is a tasty and perennially popular strain. Jack Herer has passed its genetics and part of its name on to crossbred strains like Jack the Ripper, Jack’s Cleaner, and Jack Skellington.

Although the exact genetic formula is a guarded secret, Jack Herer is thought to be the product of sativa staple Haze and a cross of Northern Lights #5 and Shiva Skunk. Sticky buds have an appealing orange-lemon scent and taste with just a hint of some dank pine. The high provides an excellent balance between cerebral and physical effects, leaving users deeply relaxed but attentive and conversant. Jack Herer’s appealing flavor and well-rounded effects has made it hugely popular with medical and recreational cannabis users alike; it has won nine Cannabis Cup titles. Cannabis lab Analytical 360 has measured Jack Herer flowers as having between 15% and 24% THC.

Jack Herer’s flowers are not particularly visually impressive: pale to medium green leaves form in densely-packed buds that are more elongated than rounded. The trichome count is high, making this a very sticky plant to handle.

What Jack Herer lacks in visual appeal, though, it makes up for in scent. Cured properly, the flowers have a deep floral bouquet with hints of orange and lemon zest. Breaking open the dense buds shows off more of the citrus scent along with a peppery kick. When burnt, the flowers give off a surprisingly clean and herbal scent, similar to sage. The very smooth and easy smoke tastes similarly herbal. Although not overwhelmingly pungent, Jack Herer leaves behind a lingering spicy-floral odor giving the general impression of potpourri.


This strain acts quickly — users are hit with a strong headrush that is noticeably more energizing than disorienting. As time progresses, or greater doses are consumed, this initial tingle spreads down the neck and through the limbs, creating a sense of relaxation without immobilizing. What follows is an alert and easily suggestible high marked by creativity. This is a particularly good strain for creative brainstorming and visualization. The sense of ease and creativity also makes Jack Herer great for facilitating conversation in social settings.

Because it provides dual relaxation and buzz for the mind and body, Jack Herer typically leaves users feeling stimulated but in full lucid control of their actions. This mellow high is good for treating low-grade stress, anxiety, and depression. Users have also described relief from migraines. Although not high in CBD, Jack Herer can also be beneficial for chronic aches and pains. It is not recommended for those suffering from insomnia, as the stimulation of thought and mood can keep users awake. More of a daytime treat than an evening medication, Jack Herer could be considered an ideal “wake and bake” strain.


Seeds of Jack Herer are available from the strain’s creator Sensi; alternatively, prospective growers can obtain mature clippings from healthy plants in order to grow clones. Sensi describes four distinct phenotypes of Jack Herer: two that lean indica and two that are predominantly sativa. Outdoor growers should plant in Mediterranean-like climates that maintain daily temperatures between 72 and 80℉. Plants can reach heights of 8 feet in certain conditions, so indoor growers should be sure to curb the height of Jack Herer by topping and by flowering soon after the plants take root. Jack Herer typically has a lower than average yield. It flowers within a comparatively long 10 weeks when grown indoors and is ready for harvest in mid to late October.

Jack Herer’s well-rounded high makes it a great strain for cannabis newcomers. It’s uniquely social in its ability to facilitate conversation while allowing users to maintain a semblance of awareness. The rich, floral scent is bound to attract attention — which may alternately be a conversation starter or a way to attract undue attention. Jack Herer is also a solid option for solo consumption, as it allows for creative thinking and a soaring sense of euphoria.

Auto-Flower variety: OMG, so quick and thick buds. Don't harvest too early, wait another two weeks, then pull the cork.Truly a classic, tasty, and healthy.

I live at the 51rst. parallel and have grown JH for the last 15 years with two dozen other strains. Jack is everything that is advertized. I find that Jack Herer and one other strain, Durban Poison, are the only ones that stimulate the thinking process and increase creativity significantly without putting you to sleep. The energy level that the creativity causes can however be draining . It is may go to strain if I have to think my way through some very big deals.

Best sativa for me, as a 30 yr old, autistic guy. I vape my weed-, and the effects are as described. Vaping JH, makes me feel more like my true self, less anxiety and stress, I like to talk more, and am better at wording my thoughts. Just be careful to take it with people you trust, because you might overspeak.
