The cream of the crops and perhaps the most exquisite ganja you will ever encounter; this strain ranks as the most awarded variety in the history of harvest festivals. Nine awards and counting would be the pinnacle of recognition for any strain, yet Jack Herer manages to go a step further and bears the distinction of being distributed under prescription by Dutch pharmacies as a recognised variety of medicinal-grade cannabis.

Sensi’s champagne of strains is named in honour of Jack Herer, author of The Emperor Wears No Clothes. Through tireless activism and his landmark book, Jack Herer can take most of the credit for reminding the world that cannabis in all its forms has always been one of humankind’s most valuable resources, and that we can literally save the planet with hemp!

The sublime blend of tropical Sativa high and monstrous Indica resin production captured in Jack Herer must be seen and sampled to be believed. At their peak, buds are so thickly smothered with clear trichomes that they appear sugar-frosted or sparkling with dew-drops. This crystal-coating extends to spear-leaves, fan leaves and even to Jack’s stems and stalks.

Plants from seed show favourable variation, due to Jack Herer’s complex background and delicate balance right at the cusp of Sativa and Indica. Enhanced features from both sides of the family are strongly evident and are expressed in different combinations, allowing growers to select mother plants tailored to their circumstances and tastes.

Three of Jack’s four main phenotypes are heavily Sativa-influenced while the fourth has a growth pattern leaning towards Indica - fast-flowering and relatively compact with a dense, expansive, rounded bud structure that’s suited to cash-cropping. Jack’s Sativa phenotypes can also produce a good per-metre or per-plant yield when cultivated skilfully, though it is rare for these crops to be sold commercially. Most growers who have watched their succulent, super-sized calyxes swell and mature will be hesitant to sell such buds, and the best Jack Herer is often passed around a select circle of friends - an example of one of those things that money just can’t buy.

The trait common to all Jack Herer phenotypes is a dazzling double-edged potency - a stratospheric cerebral high underpinned by a breathtaking body-buzz with seismic power. Smokers should be prepared to feel the earth shake beneath their feet - which can be a very pleasant feeling when your head is firmly in the clouds.

Grow your way to heartfelt happiness

by MidNightToker on 26-12-2014

I purchased a 10 pack, and had 810 germ and of the plants I had 68 females. When you put this plant into bloom, she will continue to stretch until the end of week 4, with the indica phenotype being less stretchy. I grew the plants organically but noted that starting around the third week of bloom they were VERY heavy P feeders. I top dressed with P guano to counter as well as dumping on heavy quantities of P based organic nutes. The plants are crystal and resin coated, but they never expressed a heavy Mg uptake. The wording of the description of the strain appears to good to be true (TGBT) but I assure you, these plants are like blessed tower makers. I had a good variety of phenotypes, including the one I know as Jack Herer from previous samplings, a lime one, an extremely dank skunky one that grows like a sativa, and a hazey smelling indica. minimal effort during trimharvest. It is not hard to imagine finding a valued keeper mother plant, in fact you may find yourself having difficulty reducing them to merely 1.

Reminds me of the weed in the early seventies, physcedelic without sedation.

I was so tired of the same old Kush buzz that I considered quitting my habit of forty years. The Jack Herer strain that my buddy purchased from you guys renewed my faith in smokables as a viable escape from everyday stress. Gonna try growing out a few cuttings myself.

Very good strain.

by Kelsey Bouchard on 26-9-2014

I find this strain helps me with my nerve pain and I tend to use it more as a daytime pain relief . It didn't seem to help me as much as other stains for muscle and chronic joint pain. I would recommend for diseasesdisorders such as FM. Would not recommend for nightbedtime usage. I found the effects varied very little from dispensary to dispensary. Pretty solid genetics.

One of the best highs I've ever gotten I strongly reccomend this strain

Jack legendary Herer

by Speedfiend111 on 27-4-2014

This legendary strain goes way back to its roots named after this famous person who brought allot to the medical strains I went with this strain after meeting sensiseeds in Telford uk at hemp expo I went with staff who helped me choose and this strain is one of the best if not the best pleasant feelings with a numb like stone


by Terry Ashland on 15-4-2014

this is the best iv had thanks seeds 5********

excellent medicinal qualities

by sniff my fingers on 15-4-2014

Grew this as medicine for a patient suffering fibromyalgia, rheumatoid& osteo athritis. Almost immediate relief. This strain was easy to grow (outdoors) (Southern Hemisphere). Once harvested and cured, I placed it into vaccuum sealed bags. This seemed to improve the flavour even more. Highly recommended. Sensi...you rock!

Amazing Strain

by Polly on 5-4-2014

Some of the best cannabis I've seen in years. None can match up to Jack Herer.

I always like Jack Herrer

by Ziggy Majewski on 31-3-2014

I always like Jack Herrer . I find her to be very beautiful plant an when it doubt. I always underestimate this plant due to her smell. which is unlike any smoke I had before. I make sure to roll a big j. I inhale the sweet and smooth smoke. Wonderin if I should smoke more . she creeps up on me slowly an surely. The effects come on slow an calm feeling washes over me like a warm Sunday.As time passes the effects get stronger an amazed to see how long they high lasts. Getting lost in a moment. A reason why the Emperor wears no clothes. You feel true and free
