Basic / Breeders Info

Jack Herer (aka Bedrocan) is an indica/sativa variety from and can be cultivated indoors (where the plants will need a flowering time of ±60 days) (as like as outdoors in the right climate zones). Sensi Seeds' Jack Herer is a THC dominant variety and is/was also available as feminized seeds.

Sensi Seeds' Jack Herer Description

Sensi Seeds Jack Herer 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!

After several years of breeding and stabilising, the Jack Herer strain was launched in 1994 during a ceremony in The Cannabis Castle. This was done in the presence of the most important figures in the cannabis industry and, of course, of the man himself, who triumphantly enjoyed this moment.

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.

HZ C male produced 5Hz1 which won a Cup or 2, this was a daughter of NL5 which won a cup. 5Hz1 when crossed with Sk1x HzC produced Silver Haze which won a Cup. Ben renamed it Jack Herrer.
The original JackHerer cutting was a selected NL5xHzC X SK1HZC

High Times about the lineage:
While Sensi say the exact lineage is a closely-guarded secret, it is accepted that Jack Herer is a 3-way hybrid of Skunk #1, Northern Lights #5 and Haze. The precise lineage is probably Haze x [Northern Lights #5 x (Northern Lights #5 x Skunk #1)] which suggests that Sensi began by selecting a male from their NL5 x SK1 seedline (AKA Shiva Skunk) and backcrossing him to the NL5 female cutting. As Sensi purchased Neville's breeding plants, they had both the Haze A and C males, so it is likely that they then chose a female NL5 x (NL5xSK1) plant and pollinated it with one of the Haze males to create Jack Herer., this would make Jack 50% Haze, 37.5% NL5 and 12.5% SK1. This gives Jack Herer a similar composition to Super Silver Haze and Mango Haze which are 50% Haze, 25% NL5 and 25% SK1.

This comment is connected to a Jack Herer review!

Put 5 seeds into earth, all germinated. Three feminin, two men had to go. Raised below a 125W ESL, this must be considered when reading my report! Good harvest for this equipment. Harvested the first a bit too early, but the high was excellent! As far as I can say, it was a fantastic Mix of a sativa and an indica-High. The two others I will harvest soon. Explicit recommendation! Will report more, when the others are done.

17.05.2016 Have taken a little bud and put it into the oven to dry it fast. Not the best method, so even more updates may follow. Two characteristics must be mentioned. Number one, which happened both times is, that it is very euphoric! Had to laugh a lot and even my wife asked me to take it again. Second: it relieves pain! I had a broken rip, very intense pain. So, after vaporizing a little piece the pain did not vanish, but it was softer, a lot softer! That was an enormous relieve which I enjoyed deeply. Cool, a DEFINITE recommendation! Maybe I give another update when trying the finished version of my buds. A night later I tried a differnet strain: EasyBud. There was no comparison, Jack Herer from SensiSeeds is a special one! Two thumbs up!

24.03.2017 After growing some Indica-weed I have to underline that Jack Herer is special. A wonderful plant, I do appreciate the turn so much! Still my highest recommendation.


24.07.2017 2 more seeds that sprouted all - nice quality. One was a cripple but now looks good. Today week 8 hast started, since a week light is in flowering mode.

03.08.2017 Because of lice everything seems to delay. Nearly three weeks flowering and still no gender.

16.08.2017 I'm so lucky, both are females. So another two Jacks will be harvested in - lets say: two months plus/minus two weeks. GREAT! :)

20.10.2017 Harvest 5 and 4 days ago. Drying is in process. Test and report will follow soon.

23.10.2017 Tested the first harvested one. Very nice turn, with a slight plus on the sativa turn. Still my recommendation! this comment

First of all. This is an expensive strain so the seeds are mostly lying around some time in some shop hopefully in the fridge.

Bought the seeds online at the sensi seeds shop at the beginning of the year and told them i want freshest stock they have got.

Germinated 5 seeds all sprout 4-males 1 very nice girl. With a real haze smell fat calyx and fast growth and 10 weeks bloom. Very nice.

Next 5-seeds 2-girls 3-males. 1 girl with extreme long flowering maybe 16-20 weeks was cut down because of it is unpractical for indoor.

The second is a nice girl with small calyx but fat buds and a good production of bud-mass.

The smell on the two girls is nearly the same just the structure is complete the opposite.

Overall a nice strain for the grower who knows what to expect. this comment

Jack Herer/Super Silver Haze - Amnesia cut

Understandable why the original breeder(s), whomever that is, might wish to hold back some information, and indeed may wish to hide their best creations within a sizeable gene pool to ensure a degree of exclusivity. this comment
