Amnesia Auto is the autoflowering expression of the celebrated Amnesia line, created by World of Seeds Bank to compress the classic Haze experience into a fast, day-length-independent plant. The breeder blended ruderalis, indica, and sativa components to capture Amnesia’s euphoric, citrus-incense character while enabling a seed-to-harvest timeline suitable for shorter seasons. This development aligned with the broader shift of the early 2010s, when growers sought rapid, discreet crops without sacrificing potency. Typical seed-to-harvest durations of 70–85 days made Amnesia Auto an immediate contender for northern latitudes and high-turn indoor gardens.
The Amnesia family’s influence is documented across the modern market, with numerous spin-offs and specialized versions reflecting sustained demand. Even general industry resources catalog variants such as Amnesia Auto CBD and Amnesia Bilbo Autoflowering, underscoring the strain’s branching gene pool. This breadth signals how breeders continually adapt the Amnesia archetype to distinct therapeutic and recreational priorities. Amnesia Auto sits within that ecosystem as the go-to auto for classic Haze brightness on a compact timeline.
Breeding notes from outside projects illustrate how Amnesia-based autos are valued for terpene density and autoflower genes. For example, a Strawberry Banana Auto program publicly referenced the deliberate selection of Strawberry Amnesia Auto to carry an autoflower allele alongside a large terpene load. While not the same line, it exemplifies how Amnesia-derived autos are routinely tapped to elevate aroma and flavor while keeping the fast-cycling trait. This pattern echoes why World of Seeds targeted Amnesia in the first place: a terpene-forward Sativa profile anchored to reliable ruderalis timing.
As autos matured, performance gaps with photoperiods shrank, and Amnesia Auto benefited from these breeding gains. Growers report indoor yields of 350–500 g per square meter under optimized LED intensity, a benchmark that was rare for autos a decade ago. With potency often in the mid-to-high teens and reaching into the low-20s percent THC under ideal conditions, Amnesia Auto reshaped expectations of what a sativa-leaning auto can deliver. Its steady adoption reflects the consistent balance of speed, aroma, and uplifting effects.
Genetic Lineage and Breeding Rationale
Amnesia Auto descends from a three-part heritage: ruderalis for autoflowering, indica for structural reliability and resin density, and sativa for the cerebral Amnesia signature. World of Seeds Bank selected an Amnesia-leaning parent to preserve the familiar citrus, spice, and incense bouquet. That parent was paired with a vigorously autoflowering ruderalis donor and stabilized to ensure reliable flowering irrespective of photoperiod. Subsequent indica influence was used to tighten internodes, enhance calyx density, and keep indoor heights manageable.
In practice, phenotypes often express as predominantly sativa with a noticeable indica backbone and a recessive ruderalis driver. A typical expression can be characterized as approximately 60–70 percent sativa, 20–30 percent indica, and 10–20 percent ruderalis from a trait perspective, though exact ratios vary by cut and environment. The ruderalis allele at the flowering locus confers photoperiod independence, which is why Amnesia Auto flowers under 18–20 hours of light. The indica portion contributes to bud weight and a more forgiving nutrient uptake profile.
Breeding autos demands careful selection to avoid the terpene and potency dilution seen in early-generation autoflowers. Over several cycles, breeders test for uniformity in flowering time, trichome density, and a characteristic Amnesia terpene spectrum dominated by terpinolene, limonene, and caryophyllene. Stabilization reduces undesirable outliers, such as overly lanky plants or low-resin phenotypes. The result is a modern auto that delivers consistent aromas, potency, and timing across most plants in a pack.
The prevalence of Amnesia-derived autos across the industry confirms that this lineage translates well into autoflower format. Not only does it keep the uplifting, cerebral high prized by daytime users, but it also maintains a distinctly Haze-like bouquet even at 70–85 days from seed. This fidelity to the parent flavor and effect profile is a notable breeding success. It explains why Amnesia is repeatedly chosen for auto conversions and as a terpene donor in new projects.
Appearance and Plant Morphology
Amnesia Auto tends to develop a medium-tall, sativa-dominant silhouette with a strong central cola and productive satellite branches. Indoors, heights typically range from 60 to 120 cm depending on pot size, light intensity, and training. Outdoors in warm seasons, plants may reach 80 to 140 cm, especially when started early and given ample root volume. Internode spacing is moderate, enabling good airflow while still stacking sizable buds.
The leaves show a sativa influence with narrower leaflets and a lighter, lime-to-emerald green hue during early growth. As flowering advances, the canopy takes on a slightly deeper green, and some phenotypes exhibit subtle purple or lavender touches under cool nights. Buds form into elongated spears with a medium-high calyx-to-leaf ratio, promoting efficient trimming. The pistils start ivory to light peach and ripen to orange and amber.
Trichome coverage is abundant by week 5–6 of flower, with frosty resin easily visible across calyces and sugar leaves. Under optimized lighting, milky trichomes dominate in the final 10–14 days, with 10–20 percent amber often marking preferred harvest windows for a balanced effect. Dense colas can develop notable weight, so gentle support with stakes or netting improves uniformity. The plant’s moderate leaf mass enables selective defoliation without overexposure.
In high heat or excessive PPFD, some phenotypes exhibit mild foxtailing, a trait common to sativa-influenced genetics. Keeping canopy temperatures in the 24–28°C range during late bloom helps lock in dense, conical buds. Relative humidity in the 45–55 percent range minimizes botrytis risk as the colas tighten. Overall, Amnesia Auto produces visually striking flowers that mirror classic Haze structure in a compact timeframe.
Aroma
Amnesia Auto’s aroma is a bold fusion of citrus zest, sweet herbs, spice, and incense, with many noses also picking up cedar and pine. The top notes often open with lemon and orange peel, followed by a hazy, floral-woody heart. As plants mature, a sweet, almost candied undertone emerges, especially in phenotypes with stronger limonene and ocimene content. A light pepper snap is common near harvest, courtesy of caryophyllene.
Aroma intensity is medium-high to high, easily noticeable in small grow spaces by week 4–5 of flower. Many growers rate the smell as a 7–9 out of 10 in terms of pungency, meaning adequate carbon filtration is essential. As a guideline, a quality carbon filter rated at 400–600 cubic meters per hour per square meter of canopy is prudent for odor control. Maintaining negative pressure and replacing carbon annually preserves odor scrubbing efficiency.
During drying, the bouquet shifts toward incense and citrus oil before returning to a rounder, fruit-spice blend in cure. A steady slow-dry at 18–20°C and 55–60 percent relative humidity for 10–14 days retains delicate top notes. When properly cured for 3–4 weeks, the citrus brightness and sweet spice become more defined and persistent. Stored at 58–62 percent relative humidity in airtight containers, the aroma remains vibrant for months.
Terpene evaporation is a real concern with citrus-forward profiles. Avoid drying above 22°C and keep strong airflow off the flowers to limit volatilization of monoterpenes like limonene and terpinolene. Gentle air exchange and darkness reduce oxidative losses during the critical post-harvest window. These simple steps can retain several percentage points of terpene content by weight.
Flavor
The flavor of Amnesia Auto leans into lemon-lime citrus over a backbone of sweet herb, spice, and classic Haze incense. On the inhale, bright zest and floral wood land first, followed by a peppery tickle at the back of the throat. On the exhale, a rounded sweetness, faint pine, and lingering spice complete the profile. The aftertaste is crisp and perfumed, with a resinous echo that lingers for several minutes.
Vaporizing this chemotype at 175–190°C highlights citrus and floral notes while softening any pepper bite. Combustion delivers a more pronounced incense tone, which some connoisseurs prefer in traditional joints. A proper cure significantly elevates mouthfeel, reducing harshness and sharpening zest. Most growers report a noticeable improvement between week 2 and week 6 of curing.
Moisture content strongly shapes flavor delivery, with 11–12 percent water by weight often ideal for a smooth burn. Over-dry flowers can taste flat and peppery, while overly moist buds dull the citrus and risk uneven combustion. Using humidity control packs at 58–62 percent helps maintain consistency after the cure. Grinding immediately before use preserves volatile top notes that otherwise dissipate.
Among autos, Amnesia Auto stands out for the persistence of its Haze-like character even at shorter maturation windows. The combination of terpinolene-forward brightness and caryophyllene spice is not easily confused with other citrus cultivars. This makes it a reliable choice for those who want classic Amnesia flavor without the photoperiod wait. It pairs especially well with daytime beverages like green tea, yerba mate, or sparkling water with lime.
Cannabinoid Profile and Potency
Amnesia Auto typically tests in the mid-to-high teens for THC, with many phenotypes falling in the 16–20 percent range under standard indoor conditions. Exceptional runs under high PPFD and dialed nutrition can push potency into the 21–23 percent bracket. CBD is generally low, often 0.1–0.8 percent, preserving a THC-forward experience. Total cannabinoids often land between 18 and 26 percent when minor cannabinoids are included.
Secondary cannabinoids such as CBG can appear at meaningful levels, commonly 0.5–1.5 percent in well-grown flowers. Trace THCV is sometimes detectable, typically 0.1–0.4 percent, which some users associate with a clearer headspace. The cannabinoid balance reinforces an uplifting, cognitive effect with minimal sedation from CBD. However, individual variability and environmental factors can shift these ranges.
For context, cannabinoid yields can be estimated from production data. If a grower harvests 450 g per square meter at 18 percent THC, that equals approximately 81 g of THC per square meter of dried flower. At 20 percent total cannabinoids, that same harvest would contain around 90 g of total cannabinoids. Such calculations help optimize extraction planning and set expectations for concentrate production.
Light intensity, DLI, and harvest timing all influence potency in measurable ways. Pushing PPFD to 700–900 µmol per square meter per second during mid to late bloom can increase THC by 1–3 percentage points over low-light grows. Likewise, harvesting when trichomes are predominantly milky with 10–20 percent amber tends to capture peak THC while preserving a bright terpene profile. Overripe harvests often show a small THC decline and a heavier effect profile.
Terpene Profile and Aromatic Chemistry
The terpene profile of Amnesia Auto is commonly terpinolene-dominant, a hallmark of many Haze-leaning cultivars. In representative lab analyses for similar Amnesia expressions, terpinolene can account for 20–35 percent of the terpene fraction. Myrcene frequently follows at 10–20 percent, contributing herbal sweetness and mouthfeel. Caryophyllene often ranges from 8–15 percent, bringing peppery spice and CB2 receptor activity.
Limonene typically lands in the 8–14 percent range of the terpene fraction, supplying the citrus core. Ocimene is present in many plants at 3–8 percent, lending floral-fruity top notes but evaporating easily during dry and cure. Humulene is often 2–6 percent, adding woody dryness and subtle bitterness. Linalool appears in smaller amounts, usually 1–4 percent, providing a trace of floral calm.
Overall terpene content by dry weight tends to sit around 1.5–3.0 percent in dialed indoor runs. Heat stress and rapid drying can reduce this by noticeable margins, especially for monoterpenes like terpinolene and limonene. Slow, cool drying and airtight curing protect the profile, preserving both intensity and complexity. Proper storage away from light also minimizes oxidation and terpene loss over time.
The interplay of terpinolene, limonene, and caryophyllene helps explain the signature effect curve. Terpinolene and limonene are commonly associated with alertness and mood elevation, while caryophyllene’s CB2 affinity may offer a calming edge on systemic inflammation. The result is a bright, functional clarity with enough body presence to feel grounded. This synergy is why Amnesia Auto’s aroma translates so cleanly into its experience.
Experiential Effects and Consumer Reports
Amnesia Auto is widely described as uplifting, clear, and mentally expansive, matching expectations for an Amnesia descendant. The onset from inhalation is typically felt within 2–5 minutes, with a noticeable wave of energy and a sharpened sensory field. Many users report enhanced focus and mood during the first hour, often transitioning to a smooth, optimistic calm by hour two. Total duration commonly spans 2–3 hours for inhalation, depending on tolerance and dose.
The headspace is energetic rather than racy when dosed conservatively, making it suitable for daytime creativity, light exercise, and social settings. The indica underpinning keeps the experience anchored, avoiding the jitteriness sometimes associated with pure Hazes. At higher intake, some individuals can experience anxious edges or racing thoughts, particularly if sensitive to THC or terpinolene-leaning chemotypes. Moderation and set and setting remain important variables in shaping the experience.
Flavor and effect coherence is a strong point; the citrus-spice palate maps to a bright, motivated mood. Many consumers use Amnesia Auto as a task-positive cultivar for brainstorming, art, or tackling chores. Compared to sedating indicas, it scores higher on alertness and lower on couchlock, even as it produces palpable relaxation in shoulders and neck. Appetite stimulation is moderate, generally arriving later in the session.
Novices benefit from careful titration, starting with one or two small inhalations and waiting five minutes before redosing. Experienced consumers often find 1–2 moderate inhalations sufficient for productive daytime use. When using edibles made from Amnesia Auto, expect a slower onset of 45–120 minutes and a total duration of 4–6 hours or more. Always adjust based on personal physiology and prior THC exposure.
Potential Medical Applications
While formal clinical data specific to Amnesia Auto are limited, its cannabinoid-terpene ensemble suggests several plausible therapeutic niches. The uplifting psychological profile can be attractive for situational low mood, apathy, or fatigue, where a gentle energy lift is desired. Terpenes like limonene and terpinolene are frequently cited for mood-brightening and alertness, respectively, complementing THC’s dopaminergic effects. Caryophyllene’s action at CB2 may add a mild anti-inflammatory dimension to the experience.
Chronic pain patients who prefer daytime function sometimes report benefit, particularly for neuropathic pain with a stress or mood component. Because CBD is typically minimal, those seeking anxiolysis without euphoria may consider blending with a CBD-rich cultivar or extract. For some, the cultivar supports focus and flow, which can aid task initiation in attention-related challenges. However, individuals with anxiety sensitivity should approach cautiously due to the energizing headspace.
Nausea control may be modest to good depending on dose, as THC has established antiemetic properties. Appetite enhancement is present but usually less forceful than heavy indica chemovars. Migraineurs occasionally note relief when dosing early in the prodrome, though triggers vary widely and medical guidance is essential. Patients should always consult professionals to tailor cannabinoid ratios and delivery routes to their conditions.
Pragmatic dosing guidelines can improve outcomes. For inhalation, one to two small puffs, wait five to ten minutes, then reassess, is a sensible start for new users. For oral ingestion, begin with 2.5–5 mg THC and wait at least two hours before adjusting. Vaporizing at 175–185°C may preserve brighter terpenes and deliver a cleaner, more controllable effect curve for sensitive users.
Comprehensive Cultivation Guide
Amnesia Auto is engineered for speed and aroma, rewarding precise environment control with photoperiod-level quality. From seed, plan for 70–85 days to harvest in most rooms, with faster phenotypes finishing near day 70 and more resin-forward plants running to day 80–85. Because autos begin flowering on their own schedule, minimize transplant shock by starting in final containers whenever possible. A common indoor pot size is 8–12 liters for soil or 10–15 liters for coco, providing ample root space without oversizing.
Germination is straightforward with the classic soak and paper towel method, followed by planting 1–2 cm deep. Maintain 24–26°C during sprout and 65–70 percent relative humidity for the first 7–10 days. Early vigor is boosted by gentle light at 200–300 µmol per square meter per second in week one. Elevate to 400–500 µmol in week two as roots establish.
Light schedules of 18/6 throughout the life cycle are popular, striking a balance between growth and energy efficiency. Many growers push 20/4 during peak vegetative stretch for added daily light integral, then settle back to 18/6 in bloom to control heat. Mid-bloom PPFD of 700–900 µmol per square meter per second from quality LEDs supports high resin development without pushing foxtails. Aim for a DLI of roughly 35–45 mol per square meter per day in mid to late bloom for premium results.
Environmental targets should be tuned closely across stages. Run seedlings at 24–26°C and 65–70 percent relative humidity with a VPD near 0.8–1.0 kPa. In vegetative growth, 23–26°C and 55–65 percent RH with 1.0–1.3 kPa VPD encourage sturdy structure. Flowering thrives at 24–28°C and 45–55 percent RH with 1.2–1.6 kPa VPD, tapering humidity to 40–45 percent in the last two weeks to prevent botrytis.
Nutrient strategies vary with medium but should emphasize gentle ramp-ups given the short vegetative window. In coco or hydro, run pH 5.8–6.2 with EC around 1.2–1.4 in early veg, 1.4–1.6 mid veg, and 1.6–2.0 through bloom according to plant response. In soil, maintain pH 6.2–6.8 and feed modestly, as pre-amended mixes can carry autos well into mid-flower. Calcium and magnesium support are commonly beneficial under LED lighting, especially from week 3 onward.
Training should prioritize low stress to avoid stalling autos during their brief growth phase. Gentle low-stress training from day 14–21 can open the canopy, improving light penetration and lateral bud development. Many growers avoid topping, while confident cultivators may top once at the fifth node before day 21 to keep a wide, even canopy. Selective defoliation of large fan leaves around weeks 4–6 improves airflow and bud exposure without shocking the plant.
Water management plays an outsized role in auto performance. Ensure high oxygenation of roots by letting the top 2–3 cm of medium dry between waterings and using 10–15 percent runoff in soilless systems. Overwatering in the first three weeks is a common cause of stunting and later yield loss. Consider fabric pots to promote air pruning and robust root architecture.
CO2 enrichment can meaningfully bump yields if other parameters are optimized. Running 1,000–1,200 ppm CO2 during lights-on from early bloom to week 7 can increase biomass by 10–20 percent. Keep temperatures at the high end of the target range when enriching, as elevated CO2 raises optimal leaf temperature. Ensure strong, uniform airflow to maintain even distribution.
Pest and disease prevention benefits from proactive integrated pest management. Sticky cards, weekly inspections, and clean intakes help deter thrips and spider mites, the two most common pressures in indoor grows. A rotation of biological controls or mild contact sprays during vegetative growth can intercept early populations. In late flower, emphasize environmental control and mechanical removal to protect resin and flavor.
Outdoors, Amnesia Auto excels in temperate to warm climates where a 10–12 week window of stable weather is available. In northern latitudes, sowing in late May to early June positions harvest in August to early September, usually before cold, wet autumns set in. Yields of 50–150 g per plant are typical outdoors in 10–20 liter containers, rising with better soil, sun exposure, and season length. In-ground beds with rich, airy soil often outperform containers under the same conditions.
Indoor yields of 350–500 g per square meter are achievable with dense planting and even canopies. A common spacing is 4–6 plants per square meter in 10–12 liter pots when using LST to fill the footprint. Monitor stretch in weeks 3–5 from sprout as flower triggers, and use trellis netting if colas lean. Adequate dehumidification is crucial once buds gain mass.
Harvest timing should be guided by trichome color and aroma maturity. For a classic bright effect, harvest when most trichomes are cloudy with 10–15 percent amber. For a slightly heavier finish, wait for 20–25 percent amber while watching for terpene fade. Flushing in inert media for 7–10 days can improve ash quality and taste; organic soils often need only plain water in the last week.
Post-harvest handling determines how much of the citrus-incense profile survives to the jar. Dry at 18–20°C and 55–60 percent RH for 10–14 days with gentle air exchange and darkness. Cure in airtight containers, burping daily for the first week, then weekly for three to four weeks, targeting 58–62 percent RH. Well-cured Amnesia Auto maintains a sharp citrus nose and a clean burn for months with proper storage.
Across all parameters, the guiding principle is gentle consistency. Avoid sudden environmental swings, heavy pruning late in life, or aggressive feeding spikes. Because autos have little time to recover, small mistakes can compound quickly. When treated with care, Amnesia Auto repays with photoperiod-grade flavor, resin, and a fast, reliable finish.
The broader market context supports the cultivar’s relevance. References to Amnesia Auto CBD and Amnesia Bilbo Autoflowering in public resources show how this family branches into specialized roles. Similarly, breeder notes about selecting Strawberry Amnesia Auto for autoflower genes and terpene richness illustrate how Amnesia-derived autos continue to shape modern hybrids. In this continuum, World of Seeds Bank’s Amnesia Auto stands as a benchmark for speed, aroma, and classic, uplifting effect.
