Strain Spotlight: Mr. Jack
Sativa Dominant Hybrid | Available in Arizona
For cannabis connoisseurs, few names evoke nostalgia like Jack. This legendary, sweetly pine-scented, sativa-dominant strain has long honored its namesake, Jack Herer—a trailblazer in the fight for cannabis rights and freedoms. Mr. Jack is 22Red’s signature pheno-twist on the original genetics, paying tribute to a legacy that changed the game. More than just a strain, it’s a celebration of the plant’s power to uplift, inspire, and spark a revolution—one toke at a time.
Digging Into the Genetics: Why This Combo Works
Mr. Jack is built on three iconic pillars: Northern Lights #5, Shiva Skunk, and Haze.
- Northern Lights #5 adds weight and warmth to the experience, grounding the high with subtle body effects.
- Shiva Skunk brings sweet and funky depth to the flavor and rounds out the smoke with smoothness.
- Haze injects the sativa surge—mental clarity, euphoria, and a clean cerebral push that lasts.
The result is a pheno that’s rich in old-school flavor but modernized for creative output and social spark. It’s a tribute to a revolutionary strain, reborn for today’s high-functioning stoners.
Mr. Jack Terpene Highlights
Aromatically, Mr. Jack strikes a vivid chord: sweet citrus meets pine and mint, cut with a sharp herbal edge from its terpene-rich profile:
🍏 Farnesene (Sweet Apple Calm)
Often associated with fruity calm, Farnesene adds a smooth, sweet green apple undertone that softens the strain’s sharper notes. Known for its subtle calming effects, Farnesene gives Mr. Jack a grounded base layer without muting its sativa energy.
🌶 Beta-Caryophyllene (Peppery Warmth)
This terpene adds a savory, peppery depth that balances out the sweeter top notes. Known for its anti-inflammatory potential and its unique interaction with the endocannabinoid system, b-Caryophyllene gives Mr. Jack a rounded, body-aware edge.
🍋 Terpinolene (Pine-Sour Spark)
Fresh pine, sour citrus, and a spark of floral zest make Terpinolene a standout in the Mr. Jack profile. Energetic, mentally uplifting, and unmistakably bright, it pushes the aroma into classic sativa territory while delivering the heady euphoria Jack lovers crave.
🌿 Alpha-Humulene (Earthy, Herbal Snap)
Humulene brings a dry, woody-herbal element that gives Mr. Jack depth and structure. Commonly found in hops, this terpene has been linked to appetite suppression and anti-inflammatory effects—making it an ideal counterweight to the citrusy highs.
The result?
An inhale that starts zesty and sweet, dips into earthy mint, and finishes with a herbal exhale that leaves your head buzzing and your mouth smiling. This is a high that lifts you without rushing you, sharpens your senses while keeping your feet on the ground.
22Red Cultivation Insights: Notes from our Head Grower
Grow Cycle Timeline
Mr. Jack is a true legendary Sativa, easily recognized by her classic long, narrow leaves and wide internodal spacing. The signature 5-leaf structure is a hallmark of this cultivar, and ours is no exception. She’s also a heavy drinker—requiring more water than any other strain in our lineup.
Cloning takes a bit longer, typically rooting in 9–11 days, but once established, her structure develops beautifully. During the first 21 days of vegetation, Mr. Jack takes off quickly, preparing for her vigorous stretch. Once flipped into flower, she can triple in height, continuing to stretch through the fourth week. Without adequate water and nutrients, leaves may senesce prematurely, impacting yield—so attentive care is key. By weeks 7–8, she begins to naturally defoliate, and with her large fan leaves, late-stage defoliation is straightforward, improving airflow and light penetration. True to her Sativa heritage, she is generally resilient against mold and fungal issues.
Nutrient Schedule & Feeding Approach
As mentioned, Mr. Jack loves to drink. In both the mother and flower rooms, she requires 1.5x more emitters than our average plant to reach her full potential. She’s also a hungry feeder. In veg, a higher nitrogen mix supports her rapid growth, while in flower, increased phosphorus and potassium drive bud development. While she can be sensitive to overfeeding, a gradual increase in EC ensures she keeps pace with her demanding nutrient needs.
Plant Structure & Density
Mr. Jack grows tall with wide-stretching branches, so we typically lower plant density per light to accommodate her frame. Though internodal spacing is tighter in veg, it expands significantly once she takes off in flower. The buds form large lime-green clusters—not as dense as Gelato, but substantial enough to impress. Thick stems support her structure well, allowing her to hold weight without additional support, unlike strains such as Jokerz or OG.
Finishing Notes
Mr. Jack usually requires a slightly longer flowering cycle, though under LEDs she tends to finish in about 9 weeks. Reducing nitrogen in the final two weeks helps accelerate senescence, encouraging fan leaves to fade and fall naturally. At harvest, expect triangle-shaped, neon-green nugs with golden undertones, bright orange hairs, and a frosty amber trichome coat—a visual signature as bold as the high itself.
Delivering Results: COA Breakdown

On the terpene side, Mr. Jack expresses a vibrant aromatic fingerprint, totaling 22.63 mg/g of terpenes, anchored by a trio of dominant compounds. Farnesene (5.89 mg/g) leads with its sweet, green, magnolia-like notes; β-Caryophyllene (5.57 mg/g) brings peppery warmth and potential anti-inflammatory properties; and Terpinolene (5.45 mg/g) contributes fresh, citrus-pine aromatics associated with uplift and focus. Supporting terpenes like α-Humulene (1.54 mg/g), Myrcene (1.21 mg/g), and bright accents of δ-Limonene (0.56 mg/g) and α-Pinene (0.54 mg/g) round out the complexity, enhancing both flavor and experiential nuance.
The primary aroma impressions—magnolia, cinnamon, turpentine, hops, and lemon—reflect a terpene mix that blends floral sweetness with spice, citrus, and resinous depth. This terpene-driven sensory profile, combined with potent THC content and clean lab results, makes Mr. Jack a standout choice for connoisseurs who appreciate flavorful, high-clarity sativas with strong full-spectrum expression.
