Black Jack Strain Review - Why Do Potheads Love This Indica-dominant Weed?

Terpene and Taste Chemistry

Black Jack contains the following terpenes:

  • Terpinolene (as a dominant terpene)
  • Myrcene
  • Phellandrene
  • Caryophyllene
  • Valencene
  • Ocimene

Due to the prevalent terpinolene terpene, the Black Jack strain smells of earth and citrus. Phellandrene adds a distinctive pine note balanced by sweet aromas typical for myrcene. The smoke is described as heavy but smooth to inhale.

Black Jack Strain Potency and Main Effects

On average, the THC level is 17.25-20.75%. The high lasts longer than average (up to several hours). The kush should not be consumed at work as it interferes with concentration. Moreover, smokers mostly feel aroused and have giggle fits. This marijuana offers a nice balance between physical and cerebral effects. The effects are uplifting, relaxing, and anxiety-relieving.

When it is not consumed in moderation, Black Jack weed may have negative effects such as:

  • Dry eyes
  • Dizziness
  • Anxiety
  • Fatigue
  • Nausea
  • Thirst and dry mouth

Growth Tips

Many growers are familiar with the Black Jack strain because it is easy to grow. They claim that it is not demanding. It reaches only 30’’-60’’ in stature in both inside and outside conditions. When grown in a greenhouse, the plants deliver 0.5-1 oz./ft2. The harvest for outdoor herbs amounts to 10-15 ounces of dried buds per plant. The flowering time takes approximately 75-86 days, which is a catastrophe for impatient gardeners. The harvest time is expected in 92 days. Since Black Jack is very popular, its seeds are easy to obtain.


If you’re thinking of growing the plant, know that its yield is high. You can expect 250 grams per meter if you grow it indoors. This number almost doubles when you grow it this way, as you can expect up to 550 grams per meter.
