Amnesia Haze is a flagship member of the Haze family that rose to prominence through Amsterdam’s coffee shop scene in the early 2000s. Multiple European breeders stabilized their own takes on this cultivar, and contemporary lines include a predominantly sativa version distributed by Zativo. In headshops and seed catalogs, Amnesia Haze became synonymous with daytime clarity and festival-ready energy, a reputation that helped it spread globally.
While lineage stories vary, the strain’s ascent was cemented by numerous competition placings and its persistent popularity among connoisseurs. Trade publications and seed banks routinely describe it as a “super strain,” with Zamnesia highlighting its “psychedelic powers” and high prestige. In retail data from legal markets, it consistently ranks among top sativa-dominant choices, matching consumer demand for uplifting, social effects.
On consumer platforms, Amnesia Haze is routinely tagged as a high-THC type with low CBD, and community reports emphasize giggly, euphoric, and talkative moods. Leafly’s strain pages summarize these effects along with common negatives like dry mouth, dizziness, and occasional paranoia. That blend of intense cerebral lift with a sharp sensory sparkle has helped Amnesia Haze remain relevant even as newer hybrids flood the market.
The name “Amnesia” reflects the sometimes heady, dreamy nature of the high, which can feel cloud-like or “hazy” while still energizing. Sativa-leaning Hazes often occupy the sweet spot between motivation and abstraction, and Amnesia Haze became a textbook example. Over time, the cultivar inspired numerous crosses, from Amnesia Lemon to hybrids with Northern Lights, preserving its influence across breeding projects.
Genetic Lineage and Breeding
Amnesia Haze’s heritage is mostly sativa, a point reinforced by both grow behavior and user experiences. Although exact pedigrees differ by breeder, the archetype blends classic Haze building blocks with landrace influences from Southeast Asia. Many lines lean on Thai, Cambodian, and Jamaican inputs to create an aromatic, terpinolene-forward sativa profile.
European breeders refined the cultivar in Amsterdam’s unique micro-ecosystem of indoor grows and coffee shops. Zativo’s line represents one modern stabilization, maintaining the hallmark citrus-incense profile and long-flowering Haze architecture. Other seed houses have created feminized and autoflower variants, some by introducing ruderalis traits for faster harvest cycles without losing the strain’s signature top notes.
The “Haze” family is famous for terpinolene-driven chemistry, an attribute prominently featured in Amnesia Haze. This terpene backbone typically accompanies bright limonene and peppery caryophyllene, yielding the classic lemon-zest-meets-spice character. Breeding programs consistently select for this aromatic fingerprint alongside a soaring, euphoric headspace.
Hybrids derived from Amnesia Haze often attempt to reduce flowering time or boost resin output while retaining the uplifting effect profile. Northern Lights x Amnesia Haze crosses, for instance, aim to add structure and shorten bloom, without muting the “hazy” mental clarity. The resulting family tree is broad, but the core phenotype remains a tall, lanky sativa with citrus-spice terpenes and high THC potential.
Botanical Appearance
Amnesia Haze plants grow vigorous and tall, reflecting their sativa dominance. Internodal spacing is medium to wide, and branches can stretch significantly during the first two weeks of 12/12. Growers often report a 1.5–2.5x stretch from the onset of flower, which can easily push canopies too close to lights if untrained.
The buds form elongated, tapering spears rather than squat, golf-ball nuggets. Calyx-to-leaf ratios are favorable, and colas can be impressively long with a somewhat airy sativa structure. Under high light and slightly warm conditions, fox-tailing can occur, especially late in bloom.
Colors range from lime to forest green, offset by long, copper-orange pistils as maturity approaches. Trichome coverage is heavy, contributing to a sparkling frost that’s obvious even on fan leaves near the tops. Cooler night temperatures can coax subtle lavender hues but are not a defining hallmark.
Dried flowers are typically conical, with knobby calyx stacks and a touch of spire-like architecture. Grind reveals a resin-rich interior that clumps slightly, a sign of abundant trichomes and fresh terpene content. Overall, it presents as a classic Haze: elegant, elongated, and unapologetically sativa in its posture.
Aroma and Bouquet
Open a jar of Amnesia Haze and the first impression is bright, citrusy, and slightly sweet. Many batches smell like lemon zest rubbed over fresh-cut herbs, with a top note reminiscent of sweet fresh fruit—a descriptor echoed by Canadian producers profiling Haze lines. Underneath, there’s a trace of incense and sandalwood that nods to its Southeast Asian heritage.
Dominant terpinolene contributes to a piney-citrus sparkle, while limonene amplifies the lemon peel edge. Caryophyllene adds a peppery dimension, tethering the bouquet with a warm, spicy bass note. Myrcene and ocimene can add tropical undertones, framing the fruitiness without tipping it into heavy musk.
Breaking the flower releases more volatile notes, especially from the rind-like terpenes. Expect sharper, almost effervescent citrus aromas and a shimmer of floral-herbal complexity. The terpene intensity often measures in the 1.5–3.0% total range by weight in modern, well-grown batches, supporting the strain’s reputation for robust aroma.
Proper curing is critical to preserve the bouquet’s highs and lows. A 58–62% relative humidity cure window helps maintain monoterpenes that otherwise volatilize easily. When dialed in, the nose is unmistakably “Haze”: sparkling, layered, and invigorating.
Flavor and Palate
The flavor closely mirrors the aroma, leading with lemon-lime zest and sweet fruit. On the inhale, expect clean citrus and a lightly herbal top, with a crispness that recalls lemongrass. On the exhale, pepper and a faint note of sandalwood or incense appear, grounding the brightness.
Vaporizing at 180–195°C accentuates terpinolene and limonene for a zesty, sparkling profile. Slightly higher settings, around 200–205°C, unlock more caryophyllene and bring pepper-spice more forward. Combustion can obscure some top notes, but well-cured flower retains a recognizable lemon-herb signature.
Consumers often report a lingering aftertaste of candied citrus peel. A subtle floral character may emerge as the palate acclimates, particularly with slower sips in a vaporizer. The total impression is refreshing and uplifting, the sensory counterpart to its cerebral effects.
Because monoterpenes are volatile, fresh flower and airtight storage maintain flavor consistency best. Avoid heat and UV exposure, as both degrade terpenes and mute the strain’s distinctive sparkle. When stored correctly, the palate stays faithful for months, rewarding patient curing and careful handling.
Cannabinoid Profile and Potency
Amnesia Haze is widely recognized as a high-THC, low-CBD cultivar. Seed houses regularly list THC potential above 20%, and retail certificates of analysis (COAs) frequently land in the 18–26% total THC range. CBD typically measures under 1%—often around 0.1–0.7%—yielding a THC:CBD ratio that can exceed 20:1.
In well-grown samples, THCA is the dominant acidic form present in flower, with decarboxylation during heating converting much of it to psychoactive THC. Minor cannabinoids such as CBG are commonly detected in trace-to-low amounts (e.g., ~0.2–1.0% total CBG), while CBC and THCV appear intermittently. Although these minors are not primary drivers of effect, they can subtly shape the experience, especially in high-terpene lots.
Potency variability stems from genetics, cultivation practices, and postharvest handling. Light intensity, nutrition, and harvest timing can swing total THC by several percentage points between runs. Proper drying and curing further stabilize potency by protecting THCA and limiting terpene degradation.
Consumer platforms like Leafly categorize Amnesia Haze as high THC with a stimulating effect set, correlating with psychoactivity aligned to 18%+ THC. SeedSupreme’s listings reinforce the “Very High” THC bracket and “Low (0–1%) CBD,” aligning well with COAs from legal-market dispensaries. This potency profile explains the robust, vibrant effects and the potential for overconsumption in novices.
Terpene Profile and Chemistry
Amnesia Haze typically expresses a terpinolene-forward terpene profile, a hallmark of the Haze family. In many lab-tested batches, terpinolene leads with approximate ranges of 0.3–1.0% by weight in well-grown flower. Limonene is commonly the second driver (~0.2–0.6%), while beta-caryophyllene follows (~0.1–0.4%).
Supporting cast members include myrcene (~0.2–0.8%), ocimene (~0.1–0.5%), and pinene (~0.05–0.3%). Linalool and humulene appear in smaller amounts but can contribute to floral and woody nuances. Total terpene content often sits between 1.5–3.0%, with elite phenotypes occasionally exceeding that range under optimal cultivation.
Chemically, terpinolene’s multifaceted aroma integrates citrus, pine, and floral aspects into one lively top note. Limonene contributes mood-elevating brightness, while caryophyllene—unique among major terpenes for its activity at CB2 receptors—adds peppery depth and potential anti-inflammatory synergy. Myrcene shapes fruit-forward lower notes and may modestly influence perceived body sensation even in a sativa-dominant context.
Leafly’s exploration of Haze-family terpenes emphasizes the role of terpinolene and limonene in uplifting, euphoric effects. This aligns with widespread user reports for Amnesia Haze, which skew toward energized, euphoric, and social states. The terpene ensemble thus complements the strain’s high-THC backbone, producing a signature “clear but hazy” cerebral style.
Experiential Effects and Onset
Users commonly describe Amnesia Haze as giggly, euphoric, and talkative—attributes consistently reported on community platforms like Leafly. The headspace is bright and expansive, with fast-firing thoughts and a compelling urge to move or converse. Focus can merge with a dreamy edge, hence the “haze,” yet motivation typically remains intact.
Onset is rapid with inhalation, often within 2–5 minutes, reaching peak intensity at 30–60 minutes and tapering over 2–3 hours. Edible preparations extend timelines, with peak effects around 1.5–3 hours and a total duration of 4–6 hours or longer depending on dose and metabolism. The energizing tilt makes it a popular daytime choice, though sensitivity varies.
Potential negatives mirror other high-THC sativas: dry mouth and dry eyes are common, and some users report dizziness or transient paranoia at higher doses. Individuals prone to anxiety may prefer microdosing or pairing with CBD to soften the edge. Hydration and mindful pacing significantly reduce discomfort for most consumers.
Compared to lemon-skewing hybrids like Super Lemon Haze, Amnesia Haze often feels slightly more incense-spice and “floaty.” It balances sociability with a trippy, sensorial bloom—music, conversation, and creative tasks can feel charged with novelty. For many, it’s a prime festival or daylight hike companion when used responsibly.
Potential Medical Applications
Amnesia Haze’s stimulating profile appeals to patients seeking daytime relief without sedation. Anecdotally, patients report benefits for low mood, fatigue, and motivation deficits, consistent with terpinolene/limonene-forward strains that emphasize uplift. For individuals with depressive symptoms, the rapid-onset mental elevation can provide short-term relief during functional hours.
Pain patients sometimes leverage the strain’s distraction and elevated mood to reduce perceived discomfort, especially in neuropathic or stress-amplified pain. While the National Academies (2017) found substantial evidence for cannabis in chronic pain generally, strain-specific evidence remains limited. Patients often experiment with dose timing—small, frequent inhalations during activity can maintain clarity while taking the edge off.
Individuals with ADHD-like symptoms occasionally report improved task initiation due to heightened interest and novelty perception. However, overstimulation can fragment attention in others, underscoring dose sensitivity. Microdosing via vaporization (e.g., 1–2 small puffs every 60–90 minutes) is a common strategy to harness benefits while minimizing jitter.
Because CBD content is typically low (<1%), those sensitive to anxiety may consider adding a separate CBD source in a 1:2 to 1:4 CBD:THC ratio to moderate intensity. Dry mouth and dizziness are common, so hydration and seated starts for new users are advisable. As always, this information is not medical advice; patients should consult clinicians familiar with medical cannabis and start with low doses, especially with high-THC, sativa-leaning chemovars like Amnesia Haze.
Comprehensive Cultivation Guide
Overview and cycle planning:
Amnesia Haze is predominantly sativa and requires more patience than fast-flowering indicas. Expect 4–6 weeks of vegetative growth indoors and a 10–12 week flowering window, though some phenotypes finish in 9–10 weeks. Autoflower versions compress total time to about 10–12 weeks from seed but still tend to stretch.
Plan plant count and training early to manage height. Untrained plants can double—or even 2.5x—their height after flip. Many growers target 60–90 days from germination to harvest for autos and 14–18 weeks total for photoperiod runs.
Environment, light, and VPD:
Sativa-leaners like Amnesia Haze thrive under moderate warmth and abundant light. Aim for day temps of 24–28°C and night temps of 18–21°C. Maintain relative humidity around 55–65% in veg, 45–50% in early flower, and 40–45% in late flower.
Use PPFD around 500–700 µmol/m²/s in veg and 900–1100 µmol/m²/s in flower, if CO2 is ambient and leaf temps are managed. If not supplementing CO2, staying near 900–1000 PPFD in bloom is safer to avoid photo-oxidative stress. Keep leaf VPD around 0.8–1.2 kPa in veg and 1.2–1.5 kPa in bloom for optimal gas exchange.
Medium and pH:
Amnesia Haze performs well in aerated coco, living soil, or RDWC, but sativa root systems appreciate high oxygen and excellent drainage. Target pH 6.2–6.8 in soil and 5.7–6.1 in hydro/coco. Add 20–30% perlite to soil or coco mixes to improve porosity and reduce overwatering risk.
In hydro or coco, monitor electrical conductivity (EC) closely due to the strain’s sensitivity when over-fed. Start veg around 1.2–1.4 EC and climb to 1.6–1.8 EC in early bloom, peaking around 1.8–2.0 EC in mid bloom if plants are thriving. Back off if leaf tips burn; many Haze phenos yield best with moderate feeding.
Nutrition by phase:
Veg nutrition should emphasize nitrogen for rapid canopy build, using an approximate 3-1-2 NPK ratio. Supplement calcium and magnesium early, especially in coco, to prevent interveinal chlorosis and tip necrosis. Silica (50–100 ppm) fortifies stems against stretch and supports stress tolerance.
In flower, shift to a 1-2-3 NPK emphasis to support bud set and resin formation. Introduce bloom boosters cautiously; pushing phosphorus above 70–90 ppm and potassium above 200–250 ppm can cause lockouts or leaf burn if not balanced. Many growers find that keeping total EC under 2.0 and magnesium steady (60–80 ppm) prevents classic Haze finickiness late in bloom.
Training and canopy control:
Expect aggressive vertical growth—leaf tucking, topping, and low-stress training (LST) are invaluable. Top once or twice by the 4th–6th node, and use SCROG nets to spread branches horizontally, maximizing light distribution. LST maintains an even canopy, reducing apical dominance and controlling the notorious Haze stretch.
Supercropping (stem pinching and bending) can be used during early flower to tame runaway colas. Avoid severe high-stress training beyond the end of week 2 of bloom, as recovery time can reduce yields. Defoliation should be moderate: remove large fans that block sites, but preserve enough leaf mass to drive photosynthesis during the long bloom.
Irrigation and root health:
Sativas dislike waterlogged conditions—adopt a wet-dry rhythm that encourages roots to seek oxygen. In coco, frequent, smaller irrigations once roots are established help maintain stable EC and pH. In soil, water thoroughly to 10–20% runoff, then wait until the top 2–3 cm are dry before the next irrigation.
Root-zone temperatures around 20–22°C optimize uptake. In hydro, maintain ample aeration; dissolved oxygen above 7–8 mg/L helps prevent pythium and encourages explosive root growth. Enzyme products or microbial inoculants can aid root hygiene across long flowering cycles.
Pest and disease management:
Amnesia Haze’s long bloom increases exposure to pests like spider mites and thrips. Implement integrated pest management (IPM) with weekly scouting, sticky cards, and preventative measures such as beneficial mites (Neoseiulus californicus) in veg. Avoid oil-based sprays once flowers form to prevent residue and botrytis risk.
Humidity control and airflow are non-negotiable to prevent bud rot late in bloom. Use oscillating fans to disrupt microclimates, and ensure 20–30 total air exchanges per hour in sealed rooms. Prune lower larf to improve airflow and direct energy to top sites.
Flowering time, harvest cues, and yields:
Amnesia Haze usually flowers 10–12 weeks, with some phenotypes ready around day 65–75 and others stretching to day 80+. Begin checking trichomes around week 9: cloudy trichomes with ~5–10% amber often deliver peak euphoria with minimal couchlock. Letting it run longer (15–20% amber) can mellow the edge and deepen body feel.
In dialed-in indoor environments, yields of 500–650 g/m² are achievable with SCROG or multi-top canopies. Outdoor plants in warm, dry climates can surpass 600–700 g per plant if given long, sunny seasons and strong IPM. The cultivar’s structure rewards even light distribution more than brute nutrient force.
Autoflower variant notes:
Growers often remark that Amnesia Haze autos stretch substantially—plan for tie-downs to keep tops off the lights. One common report includes mild light burn when canopies rise too close, and overfeeding tendencies can magnify stress. Keep PPFD closer to 750–900 µmol/m²/s for autos unless CO2 is added, and keep EC modest (1.4–1.7) through mid bloom.
Drying, curing, and postharvest:
Dry at 18–20°C and 55–60% RH for 10–14 days to preserve monoterpenes and prevent chlorophyll bite. Once branches snap rather than bend, jar and cure at 58–62% RH, burping daily for the first week, then weekly. A 3–6 week cure magnifies the citrus-incense complexity and stabilizes the smoke.
Common mistakes and pro tips:
Overfeeding nitrogen late in veg and early flower can lead to excessive stretch and lanky internodes. Underestimating stretch is the number-one cause of light burn and uneven canopies—flip earlier than you would with indica hybrids. Keep an eye on calcium and magnesium; low levels manifest quickly under high-intensity LEDs.
Finally, resist the urge to harvest too early. Letting the strain complete its resin maturation unlocks the intricately layered aroma and the signature euphoric profile. With patience, Amnesia Haze rewards growers with premium, connoisseur-grade sativa flowers that justify the longer calendar.
