Black Jack Seeds Info

Available as feminized seeds with an equal mix of Indica and Sativa, Black Jack is well-suited for growing in both cold and warm environments, indoors or outdoors. The smoke will give you a boost of happiness while keeping you extra relaxed for quite some time.


A direct descendant of Black Domina and Jack Herer, Black Jack is like an encyclopedia of Old World genetics. Her family tree includes Northern Lights, Ortega Indica, Hash Plant, Afghani, Shiva Skunk, and Haze – amazing seeds, every one!


Buds grown from these seeds will relax you while making you feel undeniable happiness and euphoria with the right amount of energy – perfect for stress relief and lessening depression.

THC And CBD Levels

THC levels hover around 16-20% when harvested at the right time, while the CBD content remains at 1%. This is enough for Black Jack to draw its serious healing properties from both cannabinoids.

Smell And Taste

Black Jack has an herbal and sweet yet spicy and woody flavor, almost incense-like, with just a touch of citrus. This makes for a very interesting mix of terpenes to help these seeds seriously stand out from the crowd.


Outdoors, these seeds guarantee about 500-700g (17.6-24.7oz) per plant. Grown in a tent, they yield about 500-600g/m² (1.6-2oz/ft²).

Flowering Time

Black Jack needs 9 weeks to bloom indoors and is ready to harvest in early October if you choose to plant these seeds outside.

Grow Tips

Growing this resinous lady doesn’t require a lot of experience. In fact, a novice grower can have a successful cultivation following just a very basic routine. Black Jack can reach 3m (10ft) in height if planted outdoors, becoming a beautiful giant with many hairy heads. If planted indoors, the plant behaves more moderately, growing to only about 1m (3.3ft).

  • Control the height indoors with the size of the container.
  • Make the veg longer to get bigger plants at harvest.
  • She’s a branchy plant, so be sure to prune lower branches and defoliate.

Offered at a very attractive price, these feminized seeds are extremely rewarding and capable of providing you with truckloads of bud of the highest quality.

    • General impressions
      I am impressed! The smell is so sweet, but with slight touch of floral to it. It's scent cuts through all the other plants growing around it. Really nice trichrome development as well. This is day 53 of flower and it still has a while to go by the looks of it. I will grow this strain again for sure.
    • Advantages
      Great germination rate!!!
    • Disadvantages
      Can cause dry mouth
    • General impressions
      Nice strain. The germinating rate was 100%. It grows at standard rate, with a dominant not too branchy structure. The blooming is longer than expected, but with a decent amount of calyxes and trichomes, that are ready to harvest around the ninth flowering week.
      Citric and Earthy aromas with incense touches were observed during cultivation. The high is one of the best things of this variety, mixing the relax and happiness with a talkative and creative status.
