Amnesia emerged from Europe’s late-1990s and early-2000s cannabis renaissance, when Dutch and Spanish breeders were refining Haze-dominant selections for modern indoor cultivation. In coffee shops across the Netherlands, the name “Amnesia” rapidly became shorthand for an electric, euphoric sativa with an unmistakable citrus-incense bouquet. While multiple seedbanks now offer their own versions, World of Seeds Bank popularized a mostly sativa Amnesia line selected for vigor, resin production, and consistency. That focus helped shift Amnesia from a rare connoisseur cut to an accessible, reproducible seed variety.
It’s important to differentiate Amnesia from Amnesia Haze, a related but distinct cultivar that rose to fame for its classic Haze sparkle and has itself won prestigious awards. Many consumers conflate the two because both express Haze-family traits—uplifting, giggly energy and soaring euphoria. However, World of Seeds’ Amnesia typically flowers a bit faster and is bred with indoor practicality in mind compared to some longer-running Haze phenotypes. Despite these nuances, they share a lineage that emphasizes bright terpenes and a cerebral, talkative high.
Throughout the 2000s, Amnesia earned a cult following as a daytime strain that could spark creativity without sedating the body. Reports on consumer platforms consistently describe its effects as uplifting, creative, and euphoric, with a reliably high THC and very low CBD profile. These characteristics place it firmly in the “classic European sativa” category, a hallmark of the Haze family. Over time, the name became a staple on menus, particularly in markets that favor energetic, citrus-forward profiles.
Today, Amnesia remains a pillar strain in the sativa space, bridging the gap between vintage Haze character and modern cultivation demands. Its strong association with coffee shop culture still shapes expectations: zesty aroma, animated conversation, and a clean-headed buzz that can last for hours. Breeders continue to refine it, but the core identity—bright, hazy, and high-spirited—has stayed remarkably stable. For many, Amnesia is the benchmark by which other modern hazes are judged, especially when grown well and cured properly.
Genetic Lineage and Breeding Notes
Amnesia’s genetics are best described as Haze-dominant with selective hybridization to improve structure and flowering times. Across seedbanks, you’ll find lineage notes pointing to Southeast Asian sativas—Thai and Cambodian influences are commonly cited—tempered by Afghani or Skunk heritage to add backbone and reduce the exceptionally long flowering typical of pure Hazes. World of Seeds Bank’s expression leans mostly sativa, which aligns with grower reports of tall, high-vigor plants and airy-to-medium bud structures. That genetic balance helps retain the zesty citrus-incense terpene profile while supporting more reliable indoor yields.
Because multiple breeders have stabilized their own versions, genetic nuances do vary. Some phenotypes lean harder into classic Haze traits, stretching aggressively and finishing toward the later end of the 10–12 week window. Others exhibit clearer hybrid vigor with slightly denser flowers and better calyx-to-leaf ratios, often shaving a week off flowering under ideal conditions. This spectrum is a feature of the broader Haze family, where small pedigree differences—and selection pressure—drive noticeable variation.
Terpene inheritance in Amnesia tracks closely with the Haze family’s euphoric signature. Terpinolene, limonene, myrcene, ocimene, and beta-caryophyllene are often highlighted, with terpinolene and limonene driving the bright, uplifting top notes. Breeding efforts typically aim to lock in those aromatics alongside better internodal spacing and resin density. The result is a cultivar that feels classic in the nose and head but modern in the grow room.
In practical terms, Amnesia’s lineage translates into high light tolerance, brisk metabolism, and a propensity to stretch when flipped to flower. These are hallmark sativa traits that reward training and canopy control. The hybrid touches contribute to more manageable flowering times compared to older Haze lines that sometimes push 14–16 weeks. For cultivators, the genetic picture suggests a cultivar designed to capture Haze magic without taking over the grow tent.
Botanical Appearance
Amnesia plants typically present a tall, open-branching architecture with long internodes and narrow, serrated sativa leaves. In vegetative growth, vigorous apical dominance is common, encouraging upward sprinting unless topped or trained early. Under strong light, expect pronounced lateral branching that rapidly fills space, especially with low-stress training or a SCROG. Root vigor is high, so transplanting into adequately sized containers is crucial to avoid early root binding.
Buds are generally conical to spear-shaped with a medium-airy structure, reflective of the Haze influence. Calyxes stack in columns and can produce modest foxtailing, especially late in flower under intense light or heat. Pistils often emerge pale cream to orange, darkening toward harvest as stigmas oxidize. The calyx-to-leaf ratio tends to be better than average for a sativa-leaning hybrid, making trim work manageable when properly defoliated mid-flower.
Resin coverage is one of the standout features, typically heavy across bracts and sugar leaves by week 6–7 of bloom. Trichome heads are plentiful and visibly bulbous, giving the flowers a frosty cast even before maturity. With a dialed environment, the surface can appear almost sugar-dusted under white LEDs. This resin bounty is consistent with the strain’s reputation for potency and aromatic intensity.
Coloration trends lime to medium green, though cooler nights in late flower may coax faint lavender hues in some phenotypes. Stems can exhibit purple striping under temperature swings or slight magnesium stress, but that’s cosmetic when managed. Overall, Amnesia communicates “sativa energy” at a glance: elongated structure, expressive internodes, and flowers that shimmer with volatile-rich trichomes.
Aroma
Open a jar of well-cured Amnesia and the room fills with a citrus-haze bouquet that’s both sweet and zesty. The high notes often suggest lemon zest and sweet orange with a brisk, almost fizzy lift. Beneath that brightness, there’s a classic Haze incense—woody, slightly herbal, and airy—with hints of cedar and sweet basil. Some cuts also carry a faint floral note reminiscent of elderflower or jasmine.
On the grind, the aroma intensifies and becomes more complex. Creamy, pastry-like facets can appear, similar to lemon curd on warm bread, thanks to terpinolene interacting with minor esters. A peppery-woody backbone from beta-caryophyllene emerges too, grounding the citrus into something more sophisticated. It’s a multi-layered fragrance that evolves as the flower warms in the hand.
As the cure progresses past 3–4 weeks, the nose typically rounds off and deepens. Early grassiness vanishes, replaced by clean citrus oil and a dry, resinous haze character. Past the eight-week cure mark, some jars reveal a sweet tea or honeyed chamomile nuance in the background. For many enthusiasts, that long-cure sweetness marks the difference between “good” and “great” Amnesia.
Environmental conditions can tilt the aromatic balance. Cooler, drier late-flower rooms tend to preserve bright limonene-led top notes, while warmer grows amplify sweet-herbal terpinolene. Organic soil mixes often coax more layered spice and wood compared to sterile hydro setups. No matter the expression, the overall impression stays unmistakably Haze: airy, citrusy, and confidently uplifting.
Flavor
Amnesia’s flavor mirrors the nose with a crisp lemon-lime entry that turns gently sweet on the mid-palate. In well-grown samples, the inhale can feel almost sparkling, like citrus soda with a faint botanical bitters edge. Exhale leans woody and incense-like, keeping the finish clean and dry rather than cloying. The aftertaste lingers with citrus peel, white pepper, and a hint of sweet herbs.
Vaporization showcases the terpene architecture particularly well. At 175–190°C, terpinolene and limonene shine, producing a bright, smooth vapor with minimal harshness. Raising temps toward 200°C brings out caryophyllene’s spicy warmth and a touch of resinous pine. That temperature flexibility makes Amnesia a favorite for users who enjoy tasting the full arc of a cultivar.
Combustion preserves the citrus identity but can accentuate dryness if the cure is rushed. A slow dry at 60% relative humidity and a patient cure of 4–8 weeks typically yields the smoothest expression. In joints, the profile tracks steadily from lemon to incense without unpleasant bitterness. In glass, the flavor can seem even cleaner, making subtle floral tones easier to perceive.
Nutrient management also impacts taste. Excess nitrogen late in flower can muddy the finish, dulling the citrus and emphasizing chlorophyll notes. Clean water and moderate EC during the final 10–14 days, followed by a careful dry, consistently unlock Amnesia’s zesty-sweet signature. When dialed in, it’s as refreshing on the palate as it is on the mind.
Cannabinoid Profile and Potency
Amnesia is widely reported as a high-THC, low-CBD cultivar, consistent with its Haze heritage. Contemporary lab results for similar Haze-dominant selections commonly fall in the 18–26% THC range when grown under optimal conditions, with standout batches pushing slightly higher. CBD typically registers below 1%, often in the 0.05–0.5% band, which aligns with consumer reports of a potent, head-forward high. That low CBD means minimal buffering against THC’s psychoactivity, so dose titration is important for newer users.
Minor cannabinoids appear in trace-to-moderate amounts depending on phenotype and cultivation. CBG commonly falls around 0.1–1.0%, while CBC is usually trace-level. Some sativa-leaning lines exhibit detectable THCV, frequently under 0.5% by weight in flower but occasionally higher in select phenotypes. These minors can subtly shape the energetic, appetite-modulating character often associated with Haze-family strains.
The total cannabinoid content, when combined with a robust terpene load, explains Amnesia’s reputation for a “big” but clear high. The entourage of terpenes such as terpinolene and limonene can modulate mood and perceived clarity, complementing THC’s euphoria. In inhaled form, onset is typically felt within 1–3 minutes, with peak effects at 15–30 minutes and a functional plateau that can last 90–180 minutes. Edible or tincture preparations extend onset and duration considerably, so caution is advised.
From a practical standpoint, potency varies with grower skill, environment, and post-harvest handling. High light intensity, adequate mineralization, and a stable, slow cure are strongly correlated with stronger lab numbers and better sensory quality. Conversely, heat stress, overfeeding, and rushed drying can cost several percentage points of measurable THC and total terpenes. For consumers, lab-tested batches and reputable producers are the most reliable way to experience Amnesia at its best.
Terpene Profile and Sensory Chemistry
Amnesia’s terpene profile is classically Haze-oriented, with terpinolene frequently playing a lead role. In well-expressed cuts, total terpene content often measures in the 1.5–3.5% range by dry weight, with terpinolene commonly landing between 0.2–0.7%. Limonene and myrcene tend to follow, each often in the 0.2–0.8% range depending on environment and phenotype. Beta-caryophyllene and ocimene usually contribute in the 0.1–0.5% band, rounding out the citrus, spice, and herbal elements.
Terpinolene provides the airy, citrus-forward “sparkle” often described in Haze family strains. Limonene reinforces the lemon-orange lift and is associated with a bright, cheerful mood tone in many user reports. Myrcene adds a sweet, lightly earthy undertone that can soften the edges of sharper aromatics. Beta-caryophyllene brings a peppery, woody foundation and interacts with CB2 receptors, which some users associate with a grounded finish.
Ocimene’s presence is a hallmark of certain uplifting sativas, contributing green, slightly floral top notes and adding to the strain’s “springy” freshness. Trace terpenes such as linalool, humulene, and valencene can appear in some expressions and influence subtleties like floral lift or orange-zest sweetness. These micro-constituents help explain why two jars of Amnesia grown under different conditions can smell related but not identical. The core, however—citrus, incense, sweet herb—remains consistent.
In practical terms, the Haze-family terpene suite contributes to the upbeat, talkative character associated with Amnesia. Consumer sources widely list giggly, euphoric, and talkative as prominent effects in related Amnesia Haze entries, a pattern that closely tracks here. Conversely, high terpinolene and limonene with low CBD can predispose sensitive users to transient anxiety or dizziness at high doses. That balance underscores why Amnesia is beloved for daytime creativity but best approached with measured consumption.
Experiential Effects
Amnesia’s effects skew strongly cerebral, delivering an uplifting onset that many describe as immediate mental “brightening.” Early waves often include a boost in talkativeness and spontaneous humor, making it a sociable choice. Users commonly report a crisp focus that’s well-suited for brainstorming, music, or visual arts. When the dose is moderated, the high feels energetic yet controlled rather than chaotic.
As the experience unfolds, a euphoric plateau settles in, marked by elevated mood and a smooth, anxiety-free pace in resilient consumers. This phase can last 60–120 minutes for most inhalation routes before gently tapering. The body effect remains light-to-moderate, with minimal couch lock in typical doses. That profile aligns with widespread consumer descriptions of Amnesia and its close relative Amnesia Haze as creative and buoyant.
Potential negatives track with potent sativas: dry mouth, dry eyes, lightheadedness, and occasional jitteriness at higher doses. Sensitive individuals may experience fleeting paranoia, particularly in stimulating environments or when combining with caffeine. A slow, titrated approach helps minimize these reactions, especially given Amnesia’s common high-THC, low-CBD makeup. Hydration and a calm setting further support a pleasant experience.
Time of day and intention matter. For daytime focus, microdoses or a single small inhalation are often ideal, offering clarity without overstimulation. For social settings, slightly higher doses can add laughter and conversational flow but may shorten attention spans. Late in the day, some users report a clean afterglow that doesn’t interfere with sleep, but others prefer to switch to an indica-leaning cultivar for bedtime.
Potential Therapeutic Uses
Amnesia’s energizing profile and mood lift make it a candidate for daytime symptom relief among certain patients. Anecdotal reports often mention benefits for low mood, stress-related fatigue, and creative block, consistent with its uplifting, talkative character. The bright terpene blend dominated by terpinolene and limonene may complement these effects by supporting a positive mental tone. However, individual responses vary considerably, and professional guidance is recommended.
For patients dealing with depression or anhedonia, the immediate euphoria can feel supportive in short windows of relief. Those with ADHD may find the strain’s mentally stimulating quality helpful for short bursts of focus-intensive tasks. That said, the high THC and minimal CBD content can be counterproductive for people prone to anxiety or panic, especially at larger doses. In those cases, balanced THC:CBD chemotypes or gentler terpinolene profiles may be preferable.
Some patients report moderate relief from neuropathic discomfort and migraine aura with Amnesia, possibly tied to distraction, mood elevation, and beta-caryophyllene’s CB2 activity. The body-light effect rarely provides the deep muscular relaxation associated with indica-heavy cultivars, so it may be less suited for severe spasticity or nighttime pain. Appetite stimulation can be mild to moderate depending on dose and phenotype. Overall, Amnesia aligns best with daytime, mood-forward therapeutic goals rather than heavy analgesia or sedation.
Safety considerations center on titration and context. Start low and increase slowly to gauge tolerance, particularly for those unfamiliar with high-THC sativas. Pairing with calming rituals—hydration, light snacks, and a comfortable environment—can reduce adverse reactions like dizziness or paranoia. Always consult local regulations and, where possible, medical professionals when integrating cannabis into a care plan.
Comprehensive Cultivation Guide
Amnesia thrives in environments that balance high light intensity with disciplined climate control. Indoor growers should plan for significant stretch, typically 1.5–3x in the first 2–3 weeks after the switch to 12/12. Vegetative schedules of 18/6 for 3–5 weeks are common, with early topping or mainlining to impose structure. Optimal canopy PPFD ranges from 400–600 µmol/m²/s in late veg and 800–1,000 µmol/m²/s in mid-to-late flower, adjusting by cultivar response.
Temperature and humidity targets should follow a classic VPD curve. Aim for 24–28°C in lights-on veg with 55–65% RH, then 22–26°C in flower with 40–50% RH, dipping to 38–45% in the last two weeks. Nighttime drops of 2–4°C can help tighten bud structure without stressing metabolism. Strong, variable airflow is essential to avoid microclimates on lanky branches.
Substrate choice depends on grower preference. In high-quality living soils, Amnesia often shows a more layered, spicy bouquet, while coco or hydro can maximize growth rate and yield. Keep nutrient EC around 1.2–1.6 in late veg and 1.6–2.0 in peak bloom for coco/hydro, trimming back if leaf tips burn. Soil grows benefit from measured top-dressing and careful watering to maintain aerobic conditions.
pH control is straightforward: 6.2–6.8 in soil and 5.7–6.1 in hydro/coco generally maintains nutrient availability. Watch for calcium and magnesium demands under strong LEDs, especially in coco, and supplement with 0.3–0.5 EC of CaMg when needed. Excess nitrogen post-week 3 of flower can delay ripening and dull terpenes, so taper N and emphasize K and micronutrients. Consistent, moderate feeding beats aggressive dosing with this cultivar.
Training is where Amnesia truly pays off. Topping once or twice by week 3 of veg followed by low-stress training spreads the canopy and keeps apical surge in check. A single-layer SCROG net set 20–30 cm above the canopy at the flip helps maintain an even top and improves light capture. Growers of Amnesia’s Haze relatives routinely report tying down tall limbs to prevent light burn—expect similar management needs here.
Flowering time generally ranges 65–80 days depending on phenotype and environment. Faster hybridized expressions can finish near day 65 with a clean, citrus-bright profile, while more Haze-leaning plants benefit from 72–77 days for peak terpene complexity. Stretch management during weeks 1–3 of bloom is critical; reduce day temperatures slightly and increase blue fraction if possible to help contain vertical growth. Defoliate moderately around week 3 and again at week 6 to improve airflow without stripping essential leaves.
Yields reflect both the sativa structure and modern breeding. Indoors, well-trained plants under strong LEDs commonly produce 450–650 g/m², with advanced SCROG growers occasionally exceeding 700 g/m². Outdoors in warm, dry climates, individual plants can yield 600–1,000 g with ample root space and season length. Greenhouse grows in Mediterranean conditions often achieve the best of both worlds: high quality with excellent weight.
Irrigation strategy should track plant size and transpiration. In coco, smaller, more frequent feedings maintain a stable root zone and prevent salt swings; in soil, allow partial dry-backs to encourage oxygenation. Automated drip systems paired with runoff monitoring simplify consistency during late stretch and peak bloom. Avoid large EC swings near harvest to protect flavor and burn quality.
Integrated pest management is essential for a long-flowering sativa-leaning plant. Implement weekly scouting and preventive treatments for spider mites, thrips, and powdery mildew, especially during dense mid-flower phases. Good hygiene, HEPA intake filtration, and leaf-surface airflow reduce mold risk, while silica supplementation can fortify tissue. If you’re in a high-humidity region, consider UV-C or carefully dosed biologicals as part of a broad IPM program.
Harvest timing should reflect desired effect. For the most electric, zesty expression, harvest when trichomes are mostly cloudy with minimal amber (0–5%). For a slightly rounder, calmer finish, allow 5–10% amber before chop. Flush practices vary, but many quality-focused growers provide 7–14 days of low-EC solution or clean water to improve combustibility and purity of flavor.
Dry and cure complete the process. Target 16–18°C and 58–62% RH for 10–14 days, with gentle airflow and darkness to protect volatile terpenes. Jar cure at 62% RH for at least 4 weeks, burping as needed in the first 10 days, often unlocks the full citrus-incense signature. Mature jars stored cool and dark can maintain top-tier aroma for months.
Outdoor growers should select climates with long, relatively dry autumns, as Amnesia’s finish can run into October or early November at higher latitudes. Stake or trellis early to support lanky branches and prevent wind damage. Mulch and careful irrigation reduce soil temperature swings and protect microbial life, particularly valuable in living soil setups. Always verify local laws before cultivating.
For beginners, the key pitfalls are overfeeding, insufficient training, and late-flower humidity spikes. Start with conservative nutrient levels, plan a training strategy in veg, and invest in reliable environmental control. With these fundamentals, Amnesia rewards effort with high-potency, high-aroma flowers that epitomize the modern Haze experience. Few cultivars combine such an uplifting effect with this level of sensory sophistication.
In summary, World of Seeds Bank’s mostly sativa Amnesia captures the essence of the Haze family—zesty citrus, incense, and a buoyant, creative lift—while delivering a practical, high-yield path for contemporary growers. Expect significant stretch, a 9–11 week flower, and bright terpenes that reward meticulous post-harvest handling. When executed well, the result is classic European sativa energy in a jar. It’s a living lesson in why Haze genetics continue to inspire breeders and consumers alike.
