Marijuana Strain Descriptions
Jack Herer
Cannabis Strain Summary
Terpene Profile- Primary
Terpinolene (dominant; 30-40% in typical profiles); provides fresh pine-forward notes with floral undertones; uncommon as dominant terpene in modern genetics; creates clean, bright aromatic signature
Terpene Profile- Secondary
Beta-caryophyllene (moderate; 10-15%); adds spicy, peppery complexity with woody undertones; pinene (alpha and beta; moderate); reinforces pine character with forest-like freshness; ocimene, myrcene, limonene, humulene (trace to moderate); add herbal, earthy, citrus, and woody layers
The Experience- Common Effects
Enhanced creativity and lateral thinking; improved focus without racing thoughts; uplifted mood and mild euphoria; increased sociability and conversational ease; gentle physical relaxation without sedation; sustained mental energy and motivation; heightened sensory awareness of music and visual details; described as functional and clear-headed
The Experience- Duration
Total duration 2-3 hours when inhaled with gradual tapering; peak effects 30-45 minutes post-consumption; sustained intensity for next hour before gentle decline; notably smooth comedown without crash or fatigue; edibles extend duration with clarity persisting; vaporization at 325-350°F emphasizes terpenes and cerebral effects; 375-400°F releases fuller cannabinoid spectrum
The Experience- Onset
Rapid onset within minutes; begins with cerebral head rush bringing immediate mental clarity and heightened awareness; flows into sustained cognitive stimulation with enhanced focus and mental energy; 20-30 minutes in, gentle physical relaxation emerges to ground cerebral effects without sedation; creates signature balance of mental activation with physical comfort
The Experience- Potential Side Effects
Dry mouth and mild eye dryness (common; manageable with hydration); heightened anxiety or mild paranoia possible with higher doses or in THC-sensitive individuals; can interfere with sleep if consumed too close to bedtime; mild headaches during comedown reported occasionally; start with small doses and increase gradually to find optimal range
Strain Type
Sativa-Dominant Hybrid
Not Recommended For
Late evening or bedtime use (due to energizing properties); individuals with anxiety sensitivity to sativa-dominant strains; those seeking heavy sedation or pain relief; users with very low THC tolerance without starting with microdoses; situations requiring sedation or deep physical relaxation
Lineage and Origins
Created by Sensi Seeds in mid-1990s Amsterdam to honor cannabis activist Jack Herer; three-way cross of (Northern Lights #5 x Haze A) with (Skunk #1 x Haze C); released 1994 at The Cannabis Castle; distributed through Dutch pharmacies as medical-grade strain; draws from Thai, Colombian, Mexican, and Afghani landrace genetics
Cannabanoid Profile
THC: typically 18-24% (modern selections); original 1990s releases 15-19%; exceptional specimens 25-27%; CBD: 0.7-1.0% consistently; minor cannabinoids CBG and CBC in trace amounts; potency characterized by effect quality rather than maximum THC; terpene synergies crucial to experience
Comparable Strains
Super Silver Haze (nearly identical genetics and terpene profile; higher sativa ratio 70/30; more purely energizing); J1/Jack Herer x Skunk #1 (direct descendant; sweeter aromatic profile); XJ-13/Jack Herer x G13 Haze (Haze-heavy descendant; more citrus notes); Durban Poison (pure sativa with terpinolene dominance; less physical grounding); Green Crack (comparable daytime functionality; fruitier flavor profile)
Thinking about growing your own cannabis?
Cultivation Resilience
Robust growth vigor; demonstrates resilience to common stressors with stable environmental parameters; prefers slightly lower humidity during flowering (40-50%); resistant to many common diseases when properly managed; requires attention to airflow in late flowering due to dense bud structure
Cultivation Flowering Time
Indoor: 8-12 weeks depending on phenotype (indica-leaning 8-9 weeks; sativa-dominant 10-12 weeks); outdoor: late September to mid-October harvest in northern hemisphere
Cultivation Yield
Indoor: 500-600g per square meter with proper technique; outdoor: 800-1200g per plant in optimal conditions; generous yields when well-tended; responds excellently to SOG and SCROG methods; yield quality high with proper environmental control
Cultivation Plant Structure
Medium to tall stature; sativa phenotypes show significant vertical stretch during early flowering; responds well to training techniques (topping, LST, SCROG); develops multiple productive flowering sites; requires height management in indoor cultivation; prefers stable temperatures 70-80°F (21-27°C)
Cultivation Quality Indicators
Dense, resin-saturated buds with crystalline coating; vivid green base color with abundant orange pistils; immediately apparent pine-spice aroma; trichome coverage extending to sugar leaves; proper moisture content (neither too dry nor humid); clean smoking characteristics; strong and clear effects; avoid hay-like or muted aromatics indicating poor processing
