Taste Profile



This Session Garden strain guide article provides crowd sourced information about the Jack Herer strain including the origins, THC content, appearance, effects & more.

Jack Herer is a popular Sativa-dominant strain, named after one of the most famous activists in cannabis history. Herer wrote The Emperor Wears No Clothes, a book that has often been cited in efforts to decriminalize cannabis around the United States and other countries. With such a famous and influential namesake, it stands to reason that Jack Herer is a very popular strain.

Jack Herer combines features from numerous strains, including Haze, Northern Lights #5, and Shiva Skunk. The relatively young strain is now widely available throughout the United States and is well-known for its delicious flavor and enjoyable effects. Generally, users report a euphoric high that allows for ample productivity and creativity. In addition to its mild body high, Jack Herer has been reported to relax muscles and relieve pain for some users. Thanks to its favorable effects, Jack Herer is now common among both recreational and medical users.

What is the Origin of the Jack Herer Strain?

Since the Jack Herer strain was developed more recently, much more is known about its origins. Developed by Sensi Seeds in the 1990s, Jack Herer has since gained popularity amongst growers and consumers alike. Its heavy resin production and relaxing, cerebral high make it a top choice at many cannabis shops around the country.

The Lineage Of Jack Herer

Jack Herer is a hybrid of Haze and a cross between Northern Lights #5 and Shiva Skunk. It borrows its fruity flavors and aroma from the Haze Strain, while it gets its more earthy aftertaste from the Skunk hybrid. Jack Herer is now the parent to dozens of cannabis hybrids, to which it lends its distinctive amora, flavor, and effects. Jack Herer is the parent of both Chem Jack and Lennon, among others.

Jack Herer History

Though the exact timeline is somewhat unclear, cannabis experts know that Sensi Seeds first developed the Jack Herer hybrid in the Netherlands, sometime in the mid-1990s. It was first distributed to pharmacies around the country for medical cannabis users. Sensi has guarded the exact genetics of the strain for decades to retain control over sales in the Netherlands. However, growers can now acquire cuttings of mature Jack Herer plants to create their clones. Since cannabis legalization has gone into effect in parts of Europe, the United States, and Canada, Jack Herer has become one of the most popular strains around the world.

How Is The Jack Herer Strain Grown?

Jack Herer plants require a mild to moderate climate, with temperatures ranging between 22 – 28 degrees Celsius. Growers should be aware of its sensitivity to pests, which can devastate unprotected cannabis crops. Due to this drawback, it is generally recommended that growers cultivate Jack Herer in a controlled environment.

Nonetheless, Jack Herer can be cultivated in both indoor and outdoor environments. The plant grows to be quite tall, so growers will need to keep a close eye on the plant’s access to sunlight. Growers may need to trim larger leaves on top to ensure that sunlight reaches every part of the plant. The height may also be a problem in smaller indoor environments so ample space and regular trimming are both necessary for Jack Herer plants. On average, it takes Jack Herer plants about 8-10 weeks to flower indoors, and potentially a little longer if grown outdoors.

Physical Traits of the Jack Herer Strain

Jack Herer comes from tall plants, which generally grow upwards of two meters. In addition to their large stature, Jack Herer plants are also notable for their distinctive leaves and buds.

What Does Jack Herer Look Like?

Jack Herer has many of the same physical traits as most other Sativa-dominant plants. The flowers are very dense, though relatively oblong compared to the small, round flowers of other strains. Generally, the flowers are a dull shade of green, with light yellow streaks. Additionally, they are extremely sticky to the touch, due to the high trichome count. Finally, the plant’s leaves are usually long and thin, though the color can range from very light to very dark green.

What Aroma Does Jack Herer Have?

Jack Herer does not have a singular, identifiable aroma like many other strains. However, the strain is generally known for its fruity, citrus aroma. Much like the Northern Lights strain (from which it is derived), Jack Herer also has earthy, woody undertones that linger for quite a while after consumption.

What flavours can you expect from Jack Herer?

The taste of Jack Herer is very similar to its aroma. Users report light citrus flavours that combine beautifully with earthy, woody undertones. For those who choose their strain based on flavour alone, Jack Herer can be a popular choice. That said, the flavour is somewhat mild compared to stronger citrus strains, like Super Lemon Haze.

What Effects Can You Expect From Jack Herer?

While Jack Herer can have various effects on different people, it is well-known for producing a strong “heady” high that is euphoric and energizing, without feeling overwhelming to newcomers. Thanks to its fast-acting pain relief, euphoria, muscle relaxation, and stress reduction, Jack Herer is a favourite among medical cannabis users, though it is equally popular among recreational users.

However, there’s a lot more to Jack Herer than euphoria and relaxation. The following are just a few of its most common effects:

  • Euphoria – While feelings of euphoria are pretty common among all strains of cannabis, they are particularly strong with Jack Herer. Due to its high levels of THC, Jack Herer produces strong cerebral effects that elevate mood and lower stress levels. This is why it is often used to help with anxiety.
  • Energy Level – Users generally report high energy levels when using the Jack Herer strain. Jack Herer does not have strong sedative effects, so it can easily be used at any time of day or night.
  • Creativity – Many users will have creative thoughts and ideas with Jack Herer. The reduction of anxiety allows for thoughts to flow more freely, while higher energy levels can lead to better productivity.
  • Sensitivity – Listening to music or watching movies can be much more enjoyable. Also, because Jack Herer does produce a mild body high, physical sensations are more pleasurable.
  • Relaxation – Jack Herer works extremely well to alleviate anxiety. The euphoric effects combine with muscle relaxation to help users destress and enjoy the experience. That said, like most strains that are high in THC, Jack Herer can cause paranoia in higher doses, so users should be careful about over-consuming when using Jack Herer.
  • Pain Relief – While Jack Herer does not have high CBD levels, it is still a good choice for pain relief. The body high produced by Jack Herer is strong, so when combined with the cerebral high, it produces a numbing and relieving sensation throughout the entire body.
  • Nausea Relief – Like many cannabis strains, Jack Herer is sometimes used for experiences associated with decreasing nausea and increasing appetite. This makes it a popular option or choice for users suffering from various ailments.
