Jack Herer and DJ Short are two 1970s icons in the cannabis industry. The former is an activist that advocated to legalize the use of cannabis. He authored the The Emperor Wears No Clothes, a book on the five-fingered herb and its many uses. Meanwhile, the latter is a breeding pioneer from Oregon who developed the famous Blueberry along with other flavorful, potent buds.

Using Jack Herer’s namesake strain and DJ Short’s Blueberry, breeders came up with the Sativa-leaning Blueberry Jack. It has lively, stimulating effects combined with a soothing body buzz. Keeping users from falling into a couch lock, however, is its cerebral onset.

Blueberry Jack, or Blue Jack for short, has a moderate THC level of 12% to 16%. Although lower than more modern strains, it is equally effective and enjoyable. More importantly, it is versatile. Beginners may use it as an introductory strain, while seasoned users may up the dosage for a more clear-headed and functional high without the downtime.

      Indoors, thinning it out is essential as it will help circulate air better and assist in even light distribution in the lower nodes. It works best under the Sea of Green method, which takes advantage of its stature by grouping at least four plants together in a designated area. This not only maximizes space but also increases bud production of a single cola.

      Growers may also choose between different mediums. Soil, for instance, retains terpenes better, resulting in more flavorful buds. However, using hydroponics will significantly increase bud and trichome production as well as shorten the flowering time.

      Flowering Time


      It takes between 8 to 10 weeks for Blueberry Jack to fully flower. Growers can expect each square meter to produce at least 21 ounces of buds at harvest.


      In the northern hemisphere, Blueberry Jack blossoms between the middle of October to the last week of the same month. Each plant yields at least 32 ounces of buds per square meter at harvest.
