The cultivar is particularly interesting from a genetics perspective because it combines the traditionally indica-associated Black Domina with the influential Jack Herer lineage. Current Leafly information identifies Black Jack as a cross of Black Domina × Jack Herer.
Black Jack Strain Genetics
The commonly documented genetics of Black Jack are:
Black Domina × Jack Herer
Sweet Seeds is credited with breeding Black Jack. The Black Domina side brings together several established indica lines, while Jack Herer contributes its well-known Haze-related heritage.
Leafly notes that Black Domina itself has genetic connections to Northern Lights, Ortega, Hash Plant and Afghani, while Jack Herer combines a Haze hybrid with Northern Lights #5 and Shiva Skunk genetics.
Because individual phenotypes and breeding lines can vary, breeder documentation remains the best source for confirming the genetics of a particular Black Jack product.
Black Jack Strain Profile
Black Jack is generally described as a hybrid with a complex aromatic profile.
Commonly reported characteristics include:
- Pepper
- Pine
- Tobacco
- Earth
- Herbal notes
- Spicy undertones
Leafly currently lists pepper, tobacco and pine among Black Jack’s leading flavour characteristics.
The combination gives Black Jack a more traditional, spicy and forest-like character compared with cultivars dominated by sweet tropical or dessert aromas.
Black Jack Terpene Profile
Terpenes are naturally occurring aromatic compounds that contribute to the smell and flavour of cannabis.
Current Leafly certified strain data lists terpinolene as the dominant terpene, followed by caryophyllene and ocimene.
These compounds are associated with different aromatic characteristics:
- Terpinolene — herbal, floral and fresh notes
- Caryophyllene — peppery and spicy characteristics
- Ocimene — fresh, sweet and herbal notes
The exact terpene concentrations can vary between phenotypes, growers and batches. Exact percentages should therefore only be included when supported by laboratory results for the specific product.
Black Jack Aroma and Flavour
Black Jack has a distinctive aroma that combines peppery spice, pine and earthy characteristics. Tobacco-like notes are also commonly reported in descriptions of the cultivar.
The flavour profile generally follows the same direction, with spicy and herbal notes complemented by pine and deeper earthy characteristics.
Its aromatic identity reflects the interaction between the Black Domina and Jack Herer sides of its genetic background.
Black Jack Characteristics
Black Jack is generally associated with dense, resin-covered flowers and a pronounced aromatic profile. Leafly describes the cultivar as producing thick buds with large calyxes and substantial trichome coverage.
However, flower appearance can vary according to phenotype, cultivation environment, harvest timing and post-harvest processing.
Cannabinoid concentration should also be treated as product-specific information. Generic strain databases may publish representative THC figures, but those figures should not be treated as laboratory results for every Black Jack product.
For an Australian product listing, batch-specific laboratory or product documentation should be used whenever available.
Black Jack and Jack Herer Genetics
Jack Herer is an especially important part of Black Jack’s genetic identity. Leafly’s strain research identifies terpinolene, caryophyllene and pinene as the primary terpenes of Jack Herer, while Black Jack shares terpinolene and caryophyllene but has ocimene as its third major terpene in current certified data.
This provides an interesting example of how breeding can preserve certain aromatic characteristics while introducing additional traits from another parent.
Why Black Jack Is Recognizable
Black Jack stands out because it brings together two established genetic lines: Black Domina and Jack Herer.
Its profile is particularly recognizable for its combination of pepper, pine, tobacco and earthy characteristics, supported by a terpene profile led by terpinolene, caryophyllene and ocimene.
The cultivar has also been used in further breeding. Leafly currently identifies cultivars including Sweet Cheese and Jackalope among Black Jack’s descendants.
Black Jack Strain Australia
For people researching Black Jack strain Australia, it is important to distinguish general cultivar information from the specifications of an individual Australian product.
Genetics, cannabinoid concentrations, terpene composition, flower appearance and availability can vary between producers and batches. Where available, a certificate of analysis or product-specific laboratory documentation should be used for exact cannabinoid and terpene values.
Australian cannabis products are also subject to applicable local laws and regulatory requirements. Availability and lawful supply depend on the current regulatory framework and the status of the particular product.
Black Jack Strain FAQs
Is Black Jack an indica or sativa?
Black Jack is generally classified as a hybrid.
What are the genetics of Black Jack?
The commonly documented genetics are Black Domina × Jack Herer. The cultivar was bred by Sweet Seeds.
What does Black Jack smell like?
Black Jack is commonly associated with pepper, pine, tobacco and earthy aromas, with herbal and spicy characteristics also reported.
What terpenes are found in Black Jack?
The leading reported terpenes are terpinolene, caryophyllene and ocimene, with terpinolene currently listed as dominant in Leafly’s certified strain data.
Does Black Jack have a fixed THC percentage?
No. THC concentration can vary between cultivators, phenotypes and individual batches. The appropriate THC value for a particular product should come from its batch-specific laboratory or product documentation.
Who bred Black Jack?
Black Jack is commonly credited to Sweet Seeds.
Is Black Jack the same as Black Jack Herer?
The names can sometimes be used inconsistently in cannabis markets, so they should not automatically be treated as identical cultivars. For a specific product, breeder information and product documentation should be used to confirm the genetic identity.
What makes Black Jack distinctive?
Its combination of Black Domina and Jack Herer genetics, together with a peppery, pine, tobacco and earthy aromatic profile, gives Black Jack its distinctive cultivar identity.
