Amnesia Haze (Cannabis Strain) — Strainpedia
Amnesia Haze is a renowned Sativa-dominant Hybrid celebrated for its bright citrus terpene profile, elongated flower structure, and energetic cerebral expression. Developed from a complex lineage including South Asian and Jamaican landrace influences with Afghan genetics, Amnesia Haze became a defining European cultivar in the early 2000s. Its vibrant terpene clarity and high-yield Sativa architecture positioned it as a benchmark for modern Haze breeding. This profile is provided strictly for scientific and horticultural reference.
Quick Facts
| Genetics | South Asian × Jamaican × Afghan lineage (stabilized Haze selection) |
|---|---|
| Variety | Sativa-Dominant Hybrid (~70–80% Sativa) |
| Flowering Time | 9–11 weeks (63–77 days indoors) |
| Yield Potential | 600–700 g/m² (High under optimal conditions) |
| Plant Height | 120–180 cm; significant stretch during transition |
| Climate Preference | Warm, Mediterranean climate; excels indoors with vertical space |
| Difficulty | Intermediate–Advanced (requires canopy control) |
Scientific & Botanical Overview
Amnesia Haze plants display classic Sativa architecture, characterized by elongated internodal spacing and spear-shaped colas. Flower clusters are less compact than Indica-dominant cultivars, allowing improved airflow while maintaining substantial resin production.
Trichome coverage becomes pronounced by mid-flowering, forming a bright crystalline layer across calyx surfaces. Resin glands are often clear-to-milky during peak ripening, and terpene volatility remains high through proper curing. The plant’s vertical stretch requires structural support in later flowering weeks.
Effects & Use-Cases (Reported)
- Commonly reported effects: strong cerebral stimulation, elevated mood, enhanced focus.
- Onset: rapid mental clarity and uplift, followed by light physical relaxation.
- Use-case context: daytime productivity, creative engagement, social interaction.
- Note: Observational reports only; not medical claims.
Aroma & Flavors
- Aroma: bright citrus zest, earthy spice, subtle floral sweetness.
- Flavor: lemon-forward inhale with herbal haze undertones.
- Finish: lingering citrus-pepper complexity.
- Terpene associations: terpinolene, limonene, caryophyllene, myrcene.
Tested Cannabinoid & Terpene Ranges
| Compound | Typical Range* | Notes |
|---|---|---|
| Δ⁹-THC | ~19–25% (occasionally higher) | High-potency Sativa tier. |
| CBD | ~0–1% | Trace levels typical. |
| Terpinolene | ~0.4–1.0% | Primary contributor to haze brightness. |
| Limonene | ~0.3–0.8% | Citrus elevation component. |
| Caryophyllene | ~0.2–0.6% | Spice structure. |
| Myrcene | ~0.1–0.5% | Moderate grounding effect. |
*Ranges vary depending on phenotype, cultivation methods, harvest timing, and laboratory methodology.
Cultivation Notes
- Light Cycle: 18/6 vegetative; 12/12 flowering.
- Stretch Factor: Significant during first 2–3 weeks of bloom.
- Humidity Targets: 45–50% during flower to protect elongated colas.
- Nutrition: Moderate feeder; monitor nitrogen during early bloom.
- Harvest Window: Late October outdoors (Northern Hemisphere).
Grower Notes (Week-by-Week Snapshot)
- Weeks 1–2: Strong vertical stretch; install support structures.
- Weeks 3–4: Flower sites form along extended branches.
- Weeks 5–6: Resin production increases; citrus aroma intensifies.
- Weeks 7–8: Calyx swelling and terpene peak development.
- Weeks 9–11: Final ripening; harvest based on trichome clarity for energetic expression.
- Post-Harvest: Dry at 18–20°C and 55–60% RH to maintain volatile citrus terpenes.
Genetic Lineage
Amnesia Haze blends South Asian and Jamaican landrace Sativa influences with stabilizing Afghan genetics. This fusion created a cultivar capable of high resin output while maintaining classic Haze brightness and elongated flower structure. Its popularity across European markets cemented its place as a modern Haze benchmark.
Research Insights
The dominance of terpinolene combined with limonene contributes to the cultivar’s reported energetic and uplifting profile. Caryophyllene provides structural depth, while moderate myrcene content tempers excessive stimulation. This chemotype exemplifies a bright, terpene-forward Sativa architecture with balanced physical grounding.
