Amnesia Haze emerged from the Amsterdam breeding scene, with Soma Seeds widely credited for stabilizing and popularizing this standout cultivar. In a city where Haze lines set the standard for cerebral cannabis, Amnesia Haze earned quick renown for its soaring, euphoric effects and complex citrus-incense bouquet. By the mid-2000s it had become a cafe staple and an international benchmark for modern sativa-dominant excellence.
Its trophy cabinet helped cement its legacy. Amnesia Haze is frequently cited among High Times Cannabis Cup winners of the 2000s, and it has maintained a top-shelf reputation in European coffee shops for nearly two decades. That longevity is rare; few strains sustain demand that long without periodic rebranding or novelty crosses.
Adoption spread beyond Amsterdam as seed banks feminized the line and released both photoperiod and autoflower variants. The strain’s presence on major consumer platforms underscores its popularity; it has amassed thousands of user reviews globally, with consistently high ratings and commentary on its distinctive uplift. Retail data from European and Canadian markets also shows steady shelf presence for Haze-forward sativas, and Amnesia Haze remains a reference point in that category.
The cultural footprint is also tied to the Haze family’s identity. As Leafly’s coverage on Haze terpenes highlights, this family is synonymous with bright, uplifting effects driven by a specific terpene signature. Amnesia Haze exemplifies that profile, translating the Haze mystique into a modern, reliable cultivar that growers can reproduce and consumers can recognize.
Genetic Lineage
Amnesia Haze is a mostly sativa hybrid that traces its ancestry to classic Haze genetics combined with an Afghani influence. Although the exact recipe has been closely guarded, credible accounts point to tropical sativa landraces from Southeast Asia and the Caribbean—Thai, Laotian, Cambodian, and Jamaican—interwoven with a short, resin-heavy Afghani line. This structure helps explain why the plant exhibits both towering sativa vigor and dense, frosty flowers.
Soma Seeds is commonly named as the breeder that refined this line for commercial release, an attribution repeated across seed marketplaces and breeder histories. The Afghani contribution is more than historical trivia; it likely bolsters trichome output and calyx density, improving bag appeal and resin extraction yields. Meanwhile, the sativa side is responsible for the long flowering time, zesty terpene profile, and high-energy effects.
Phenotypically, Amnesia Haze leans 70–80% sativa in most catalogs, and that aligns with how it grows in real-world gardens. The strain stretches aggressively after the photoperiod flip and forms elongated, spear-shaped colas typical of Haze descendants. Chemical clues reinforce the lineage too: a terpinolene-forward terpene profile, frequently seen in Haze cultivars, is common in lab reports for Amnesia Haze.
Hybrids featuring Amnesia Haze genetics—such as pairings with Northern Lights or Skunk lines—tend to retain the uplifting headspace while compressing flower time. These crosses demonstrate the genetic flexibility of the pedigree. They also show how the Afghani component can be dialed up or down to fine-tune structure, resin density, and finish date.
Appearance
Mature Amnesia Haze flowers are typically lime to forest green with rich amber to bright tangerine pistils. The buds are elongated and tapering, with a high calyx-to-leaf ratio that makes trimming comparatively efficient. When grown under strong light, the bracts stack into spears and can show slight foxtailing near the topmost colas.
Trichome coverage is substantial, a trait likely inherited from the Afghani side. The resin heads are abundant and give the buds a frosted sheen even before a full cure. Under magnification, capitate-stalked trichomes are dominant, which is favorable for solventless extraction.
On the plant, internodal spacing is medium to long, particularly in early flower, which is typical for Haze-dominant cultivars. Plants can exceed 120–180 cm indoors if untrained and may surpass 250–300 cm outdoors in warm climates with long seasons. Stems are moderately sturdy but benefit from trellising or soft ties due to the strain’s long, weighty colas.
Leaves are slender-fingered with a classic sativa look, though some phenotypes show slightly broader blades in early vegetative growth. Late in flower, sugar leaves can exhibit a silvered appearance thanks to thick trichome deposition. The overall visual impression is elegant and elongated rather than golf-ball chunky, reinforcing its Haze heritage.
Aroma
Open a jar of Amnesia Haze and you are greeted by a vivid citrus top note—lemon zest, grapefruit spray, and sweet tropical undertones. That brightness sits over an incense-like, woody backdrop that Haze aficionados immediately recognize. Many users also report fresh, sweet fruit aromatics, a sensory thread mirrored in Leafly’s coverage of Haze family traits.
On the nose, the bouquet evolves as it warms in the hand. Terpinolene’s piney-floral character blooms into hints of green apple and melon, while limonene boosts the sense of freshness. Caryophyllene introduces a subtle peppery-spice dimension that emerges more strongly after the grind.
In a freshly ground sample, sharper herbal notes can appear—basil, lemongrass, and a wisp of eucalyptus. A faint earthiness anchors the profile so the citrus doesn’t feel thin or one-dimensional. Well-grown, properly cured batches carry the scent across the room without becoming cloying or skunky.
Compared to lemon-centric strains like Super Lemon Haze, Amnesia Haze’s aroma is usually rounder and less candy-forward. The incense-wood facet gives it a mature, classic nose reminiscent of old-school coffeeshop jars. This balanced aromatic architecture is one reason it remains a connoisseur favorite.
Flavor
The first draw usually delivers bright lemon and sweet grapefruit overtones that echo the aroma. As the vapor or smoke saturates the palate, floral and herbal accents come forward—think orange blossom, lemongrass, and a whisper of pine. On the exhale, spice and wood trail behind with a mild pepper tickle, suggesting caryophyllene at work.
Proper curing accentuates layered sweetness rather than raw citrus bite. A 4–8 week cure in stable humidity preserves the terpinolene sparkle while smoothing chlorophyll edges. When dialed in, the aftertaste can linger as a delicate citrus tea with faint incense.
Temperature matters for flavor retention. Vaporizing at roughly 175–190 Celsius tends to foreground terpinolene and limonene, preserving delicate top notes. Moving above 200 Celsius will emphasize wood-spice depth and increase throat hit, which some users prefer for a denser, more hash-like character.
Compared side by side with other Haze-lineage cultivars, Amnesia Haze often presents less skunk and more polished citrus-herb clarity. It fits well in daytime sessions where a clean, refreshing palate is welcome. Many fans also find that its flavor remains distinct even in mixed blends or joints with multiple cultivars.
Cannabinoid Profile
Amnesia Haze is reliably high in THC, with many seed vendors and lab-tested retail lots reporting totals over 20%. SeedSupreme classifies it as very high potency, often in the 20–26% THC range for optimized indoor flowers. CBD is typically low, commonly 0–1%, and CBG is often detected in the 0.3–1.0% range.
Trace amounts of THCV have been noted in some Haze-leaning chemovars, and Amnesia Haze can occasionally show measurable THCV (for example, 0.1–0.5%). However, THCV presence and magnitude vary widely by phenotype and growing conditions. Consumers looking specifically for high-THCV chemovars should verify with batch-specific lab reports rather than relying on strain name alone.
Total cannabinoid content frequently falls in the 18–28% window for top-shelf lots, with the ratio dominated by THC. This chemotype explains the quick, assertive onset and the energizing cognitive push users report. Because of the potency, novice consumers may find that 1–2 inhalations suffice to reach desired effects, particularly in products testing above 20% THC.
Decarboxylation is efficient via smoking or vaping, but dose control is tighter with vaporizers and standardized products. For inhalation, a typical effective THC dose for many adults is around 5–10 mg equivalents, though experienced users may prefer 15–25 mg. Always titrate slowly, especially given the tendency for Haze sativas to feel more stimulating than equivalently potent indicas.
Terpene Profile
As a Haze-family flagship, Amnesia Haze commonly expresses a terpinolene-dominant terpene profile, a chemotype associated with uplifting, euphoric effects. In lab-tested samples, total terpene content often ranges from 1.0–2.5% by weight, with terpinolene frequently leading at 0.3–1.2%. Limonene, beta-caryophyllene, and ocimene are common secondary contributors, each typically in the 0.1–0.6% range depending on phenotype and cultivation.
The Haze family’s characteristic mood-elevating feel aligns with this terpene architecture, as noted by Leafly’s overview of Haze terpenes. Terpinolene provides a piney, floral, and citrus-tinged brightness, while limonene augments perceived freshness and may complement THC’s energizing qualities. Caryophyllene adds a peppery grounding note and interacts with CB2 receptors, contributing to the strain’s complex feel.
Other recurring minor terpenes include myrcene (often 0.1–0.4%), alpha-pinene (0.05–0.3%), and linalool (trace to 0.2%). While myrcene is typically not dominant here, its presence softens edges and can subtly shape body feel. Pinene may contribute to the clear, focused top end that many users appreciate in daytime settings.
Growers can influence terpene outcomes via environmental controls and curing. Cooler night temperatures late in flower and minimal handling during trimming help preserve volatile terpenes. A slow dry at approximately 60% RH and 60 Fahrenheit, followed by a controlled cure, is ideal for maximizing aromatic fidelity.
Experiential Effects
User reports consistently describe Amnesia Haze as giggly, euphoric, and talkative, echoing Leafly’s effect tags. The onset is typically fast with inhalation, arriving within 2–10 minutes and peaking around 30–45 minutes. Many note a buoyant, sociable mental state that pairs well with conversation, creative work, or active recreation.
The headspace tends to be expansive and sensory-forward, with colors seeming brighter and music more engaging. Unlike sedative indicas, this cultivar usually avoids heavy body load, instead promoting a light, mobile feel. That said, some phenotypes can deliver a gentle, warming body glow once the initial cerebral surge settles.
Potential negatives mirror classic sativa caveats. Higher doses, especially for sensitive or inexperienced users, can provoke transient anxiety, dizziness, or paranoid ideation. Dry mouth is common, and dry eyes can appear with extended sessions, so hydration and moderation are prudent.
In terms of duration, inhaled effects commonly last 2–4 hours, with a clean taper if dosing is conservative. Combining with caffeine or other stimulants can intensify the experience and may not be advisable for those prone to jitters. For daytime productivity, small, spaced doses often yield the best balance between motivation and overstimulation.
Amnesia Haze’s audio-visual enhancement and social lift make it a favorite for outdoor walks, brainstorming, and collaborative tasks. Many users also report improved focus on repetitive chores when dosing lightly. In contrast, very high doses are better suited to unstructured leisure and creative play rather than complex, high-stakes work.
Potential Medical Uses
While strain-specific clinical trials are rare, the broader cannabis evidence base and aggregated user reports offer guidance on Amnesia Haze’s potential utility. High-THC, terpinolene-forward sativas are often selected for mood elevation, low motivation, and fatigue during the day. Users commonly tag Amnesia Haze for stress relief and depressive mood, consistent with its bright, energizing signature.
For chronic pain, the 2017 National Academies review found substantial evidence of cannabis efficacy for adult chronic pain, though not specific to Amnesia Haze. In practice, many patients reserve stimulating sativas for neuropathic or inflammatory pain during waking hours, when sedation is undesirable. The caryophyllene content may contribute modestly via CB2 engagement, potentially aiding inflammatory pathways.
Attention-related concerns and daytime focus are another frequent use case. Anecdotal reports describe improved task initiation and engagement with light doses, though excessive amounts can fragment attention or provoke anxiety. As with any high-THC product, careful titration is key, starting low and gradually increasing to find the functional dose.
For mood and anxiety, results are mixed and highly individual. Some patients find that the uplifted, sociable tone enhances resilience against stress, while others experience overstimulation. Population surveys often show a subset—particularly new users—reporting anxiety at higher THC levels; choosing lower-dose formats and avoiding late-night use can mitigate that risk.
Sleep is not a primary indication for Amnesia Haze due to its energizing profile. However, by improving daytime function and reducing pain or low mood, some users indirectly report better sleep quality. When nighttime relief is needed, many patients pair a sativa like Amnesia Haze during the day with a more sedating chemovar in the evening.
Comprehensive Cultivation Guide
Amnesia Haze is a vigorous, mostly sativa cultivar that rewards skillful training and patient flowering. Indoors, expect a 10–12 week bloom (70–84 days) after the 12/12 flip, with total crop time from seed often running 16–20 weeks including veg. Indoor yields of 500–650 grams per square meter are achievable under optimized conditions, with outdoor plants producing 600–1000 grams per plant in long-season climates.
Germination and early vegetative growth are straightforward in quality seed-starting media with 20–25 Celsius ambient temperature. Maintain gentle light intensity (200–400 µmol·m−2·s−1 PPFD) for seedlings and increase to 400–600 PPFD as plants develop 3–5 nodes. Root health is critical; avoid overwatering and keep substrate oxygenated, particularly in coco or hydroponic systems.
Vegetative management benefits from early structure. Top at the 4th–6th node, then apply low-stress training to spread the canopy horizontally. Screen of Green (SCROG) and multi-top manifolds work well, helping to control stretch and create uniform light exposure for the long, sativa colas.
Photoperiod and stretch management are essential. Expect 1.5–2.0x stretch in the first 2–3 weeks of flower; some phenotypes may exceed this if vegged aggressively. Many growers flip to flower earlier than with indicas, once desired node count is established, to keep final height manageable indoors.
Environment should target moderate warmth with good airflow. Ideal daytime temperatures are 24–28 Celsius in veg and early flower, tapering to 22–26 Celsius late flower. Night temperatures of 18–22 Celsius help maintain metabolic balance; lowering nights slightly in the final two weeks can improve color and aroma retention.
Relative humidity should sit around 60–65% in veg, 45–55% in mid-flower, and 40–45% in late flower. The long flowering window increases vulnerability to botrytis, so strong, directional airflow and leaf plucking for improved penetration are prudent. Maintain vapor pressure deficit in a plant-friendly zone (approx. 0.8–1.2 kPa) to drive transpiration without stressing stomata.
Lighting should scale with vigor. In flower, 700–1000 µmol·m−2·s−1 PPFD provides strong photosynthetic drive; CO2 supplementation at 800–1200 ppm can safely raise that target toward 1000–1200 PPFD. Monitor leaf temperature and watch for light stress signs—upturned leaf edges, bleaching tops—since Amnesia Haze stretches toward light.
Nutrition is best delivered steadily rather than aggressively. Despite the sativa appetite for light, many Amnesia Haze phenotypes are medium feeders that can be over-fertilized if pushed. Aim for electrical conductivity around 1.2–1.6 mS/cm in veg, 1.6–2.0 mS/cm in peak flower, with a calcium-magnesium supplement if using RO water or coco.
pH control ensures nutrient availability. Keep soil irrigations at pH 6.2–6.8 and coco/hydro solutions at pH 5.7–6.1. Mild runoff in inert media helps prevent salt accumulation; periodic flushes or low-EC irrigations can reset the root zone if tips burn.
Training and canopy support pay off with this cultivar’s long colas. A grower anecdote from SeedSupreme’s autoflower page notes tying down multiple limbs to keep them out of the lights and encountering mild light burn and overfeeding—classic signs of sativa vigor and sensitivity. Use soft ties, bamboo stakes, and trellis nets to spread weight and maintain even tops.
Pest and disease prevention should be proactive given the lengthy bloom. Scout weekly for spider mites, thrips, and whiteflies; integrate beneficials such as Phytoseiulus persimilis for mites where permitted. Manage powdery mildew risk with consistent airflow, leaf sanitation, and avoiding large, humid microclimates in dense canopies.
Watering cadence should follow dry-back principles. In soil, water thoroughly to 10–20% runoff, then allow the pot to lighten substantially before re-watering. In coco or hydro, smaller, more frequent irrigations maintain stable EC and root oxygenation; automate if possible to reduce swings.
Flowering nutrition should elevate potassium and sustain sufficient phosphorus without overdoing it. Many successful feed programs ramp PK starting week 2–3 of flower, peaking around week 5–6, then tapering to promote clean senescence. Watch nitrogen late; excess N can delay ripening and mute aroma in Haze cultivars.
Harvest timing is critical for the desired effect. For an uplifting profile, consider chopping when trichomes are mostly cloudy with minimal amber (for example, 0–10% amber). Allowing more amber (10–20%) can deepen body feel but may reduce the sparkling, cerebral tenor that defines Amnesia Haze.
Post-harvest handling can make or break the terpene profile. Dry in 10–14 days at about 60 Fahrenheit and 60% relative humidity, with gentle airflow that moves air around, not across, the flowers. Cure in airtight containers, burping as needed to maintain 58–62% RH; optimal water activity for long-term storage is roughly 0.55–0.65.
Indoor yield expectations in optimized rooms are 500–650 g/m2 with dense canopies and adequate light. Outdoors, in Mediterranean-like climates, plants can exceed 2.5 meters and deliver 600–1000 grams per plant with a late October to early November finish. In humid, short-season regions, greenhouse cultivation with dehumidification or early-finishing hybrids may be more reliable.
For autoflower variants, expect a seed-to-harvest window of about 10–12 weeks, smaller plant size (often 80–120 cm), and reduced yields per square meter compared to photoperiods. Light intensity can remain high (DLI scaled to autos), but training should be gentler—low-stress techniques over topping in most cases. Autos still stretch and can approach lights; maintain adjustable fixtures and be prepared to tie down tops to avoid bleaching.
Organic growers can succeed with rich, living soils and top-dressed amendments. Focus on calcium, magnesium, and sulfur sufficiency to support terpene biosynthesis. Compost teas and microbial inoculants can enhance nutrient cycling, but avoid overwatering to keep aerobic conditions.
If CO2 is used, monitor closely and match with adequate PPFD and nutrients; otherwise the benefit is limited. Keep leaf surface temperatures at appropriate levels, ideally measured by infrared thermometer, to align with VPD targets. Routine defoliation is helpful but conservative; over-stripping sativas can reduce energy capture more than desired.
Quality control hinges on patience and consistency from seed to cure. Calibrate pH and EC meters monthly, verify hygrometers, and document each run’s parameters and outcomes to tune future cycles. With attention to these details, Amnesia Haze rewards growers with aromatic, high-clarity flowers that capture the classic Haze experience.
