¶ Black Jack
¶ Overview
Black Jack is a sativa-dominant hybrid that crosses the heavy, resinous Black Domina with the legendary cerebral stimulant Jack Herer. The result is a strain that blends the best of both worlds: the dense, resin-laden structure of Black Domina with the creative, uplifting sativa effects of Jack Herer. Black Jack delivers THC levels in the 15-20% range with a terpene profile dominated by caryophyllene, pinene, and terpinolene, producing an earthy, pine-forward aroma with spicy undertones. The strain is prized for its energetic and creative effects, making it a popular choice for daytime use among users who want functional cerebral stimulation.

¶ Genetics & Lineage
Black Jack combines two well-established genetics:
- Black Domina -- A heavy indica created from Afghani, Northern Lights, Ortega, and Hash Plant genetics, known for extreme resin production and dense bud structure
- Jack Herer -- The legendary sativa-dominant strain (Haze x Northern Lights #5 x Shiva Skunk) renowned for creative, uplifting cerebral effects
Parent lineage: Black Domina x Jack Herer
The cross was designed to introduce the heavy resin production and structural density of Black Domina into the creative, energetic framework of Jack Herer. The resulting sativa-dominant hybrid retains the mental clarity and creative drive of its Jack Herer parent while gaining some of the physical resin and bud density from Black Domina.
¶ Cannabinoid Profile
| Cannabinoid | Typical Range |
|---|---|
| THC (Total) | 15-20% |
| CBD | <1% (typically 0.1-0.3%) |
| CBG | 0.5-1.2% |
| CBN | <0.5% (increases with age) |
Black Jack sits in the moderate to upper-moderate THC range, providing noticeable potency while remaining accessible to users with varying tolerance levels.
¶ Terpene Profile
| Terpene | Approximate Share | Notes |
|---|---|---|
| Caryophyllene | 25-35% | Primary terpene; spicy, peppery, woody character |
| Pinene | 15-25% | Significant presence; pine, fresh aroma inherited from Jack Herer |
| Terpinolene | 10-20% | Floral, herbal, citrus notes contributing to the uplifting quality |
| Myrcene | 5-10% | Lower, consistent with the sativa-dominant profile |
| Humulene | 3-8% | Earthy, hoppy depth from the Black Domina heritage |
The caryophyllene-pinene-terpinolene combination produces the earthy, pine-forward, and slightly spicy aroma that defines Black Jack.

¶ Growing Information
| Attribute | Details |
|---|---|
| Difficulty | Moderate -- requires some experience but generally manageable |
| Flowering Time | 55-65 days (indoor) -- reasonable for a sativa-dominant strain |
| Yield | 400-500 g/m² indoor; 500+ g/plant outdoor |
| Plant Height | Medium -- sativa stretch is moderate; the Black Domina heritage keeps height more manageable than pure sativas |
| Preferred Environment | Indoor or outdoor; prefers warm, sunny conditions with good air circulation |
| Resistance | Good resistance to mold and pests. The Black Domina heritage contributes resilience. Responds well to SOG, SCROG, and topping. |
Black Jack is moderately challenging to grow. Its sativa-dominant characteristics require some height management, but the Black Domina genetics keep the plant more compact and manageable than pure sativa varieties. The reasonable flowering time (55-65 days) is an advantage. Outdoor harvest in the Northern Hemisphere typically falls in late September to early October. The dense bud structure inherited from Black Domina means growers should monitor for mold in high-humidity environments.
