Black Jack Weed Strain Review & Information

As you’ll find in this Black Jack strain review, sometimes genetic lineages get mixed up and multiple breeders take credit for a child strain. Black Jack marijuana isn’t the most well-known strain available, but its genetics make it an intriguing prospect for your next batch!

Both lineages of Black Jack weed are incredibly similar, so we’ll look at both as a singular entity here at CTU. If you want to try both varieties and let us know which one you like better, feel free to do so!

Black Jack Strain Genetics

Sweet Seeds is the company responsible for the Black Jack strain. Nirvana Seeds is responsible for the BlackJack marijuana strain. Aside from the spacing, the strains are incredibly similar even though they are produced by two different breeders.

Black Jack from Sweet Seeds is a cross of Black Domina and Jack Herer strains. BlackJack from Nirvana Seeds is a cross of Black Domina and Jock Horror, their unique phenotype of Jack Herer.

Even with these differences in genetic lineage, they come out incredibly similar, as mentioned.

Black Jack cannabis is a sativa dominant hybrid that takes on beneficial traits from both parents. It is important to note that there are so many phenotypes of Jack Herer.

The indica or sativa dominant traits that show up in Black Jack will be due to the type of Jack Herer used in breeding. While it usually leans towards sativa, you can have Black Jack lean towards indica as well, like the phenotype produced by Sensei Seeds.

Black Domina is a cross of 4 types of marijuana strains and leans way towards the indica lineage. The indica effects that are useful for treating insomnia weren’t given to Black Jack, however. Instead, the high is similar to that of its other parent Jack Herer.

Jack Herer is one of the most well-known cannabis strains and has been used to parent multiple child strains. It’s known to boost focus and creativity and leans more towards the sativa family, just like Black Jack.

Black Jack has been used to create a couple of child strains in Sweet Cheese and Jackalope.

Sweet Cheese is a cross of Black Jack and Cheese and was also created by Sweet Seeds. It is known for a lasting high with complex flavors and aroma, just like its parents.

Jackalope strain is a cross of Black Jack and Chocolope and is less well known than Sweet Cheese but still pleases its users.

Black Jack Strain Yield

Black Jack can climb and stretch vertically like a thoroughbred sativa plant. It can result in heavy harvests whether you grow indoors or outdoors. If you are growing this strain indoors you should top your crop to encourage more lateral growth or you might run out of vertical space!

Black Jack will do best with trellising since it tends to stretch far and get top-heavy, which may cause breakage in the branches before full maturity.

It’s relatively easy to grow and will provide a medium-to-large harvest as compared to other cannabis varieties.

Flowering Time

The flowering period of Black Jack is between 62-72 days. The strain is known for fat buds with large calyxes. The trichomes offer the visual of a light dusting of fresh snow. With the large variety of phenotypes of Jack Herer, it makes sense that Black Jack plants may have remarkably different features within the strain.

With this in mind, it’s important to know what the genetics of your phenotype are to ensure you provide the best growing conditions and pick your bud at the right time for the highest amounts of cannabinoids and terpenes.

Weed Strain THC Percentage

This strain clocks in somewhere between 14-24% THC. This is a wide range, so smokers should be aware of the percentage of THC in their actual batch.

Consuming 24% THC when you are expecting 14% can set you up for a heavy experience. Or, if you expect a 24% THC high but are consuming Black Jack that is only 14% THC, you’ll probably be disappointed.

Black Jack Strain Flavor & Aroma

Black Jack has a hint of berries in the aroma and the flavor, granting a sweet experience for most. It’s also known to have a more earthy, piney essence. It depends on the phenotype of Black Jack that you grow or purchase.

The variety is rich in Terpinolene, Caryophyllene, and Ocimene, contributing to the more focused and energizing experience typical with Jack Herer and its child strains.

Another phenotype was found to be richer in Pinene, Caryophyllene, and Myrcene, which would lead to a much different flavor, aroma, and experience.

It’s hard to tell what you’ll get in your specific batch of Black Jack but its noted effects for the original strain are apparent.

Medical Conditions This Pot Strain Can Help

Black Jack is known to help users with energy levels to fight fatigue. It can also boost focus and creativity, making it a good day time bud.

Medical users who struggle with conditions like ADHD, Chronic Fatigue, and Depression will have a good experience with this uplifting ganja.

The phenotypes of Black Jack that are high in THC will help users with insomnia and a suppressed appetite as well.

It’s not just a medicinal marijuana strain, however. Plenty of recreational users consume it and enjoy the benefits!

Final Words On The Black Jack Weed Strain

Some cannabis strains are well known and have fully defined genetic lineages. Others have been produced by multiple breeders and you end up with inconsistent cannabis across the strain.

This may have an effect on the popularity of strains like Black Jack, since cannabis users like a predictable experience when using a certain strain time and time again.
