Amnesia Auto is the autoflowering rendition of the iconic Amnesia family, developed by Kera Seeds to deliver the unmistakable Haze-forward experience in a faster, more manageable package. By introducing Cannabis ruderalis genetics into a proven Amnesia cut, Kera stabilized an auto that preserves the uplifting, citrus-and-incense character while finishing far quicker than photoperiod Hazes. The goal was straightforward: compress the notoriously long bloom of Amnesia into a seed-to-harvest schedule of roughly 10–12 weeks without diluting potency or aroma. The result is a modern auto that behaves like a compact, day-neutral Haze hybrid with sativa energy and surprising resin density.
The Amnesia lineage itself traces to Dutch breeding programs that married classic Haze lines to select indica stock for structure and density. While multiple versions exist, most Amnesia cuts are sativa-leaning, carry strong terpinolene-forward bouquets, and were historically celebrated in the Netherlands for their cerebral punch. The challenge with translating that character into an auto is that ruderalis additions can blunt terpene intensity and THC output. Kera’s work shows how far autos have come in the last decade, closing the gap between photoperiod vigor and autoflowering convenience.
Context from today’s seed market underlines how influential Amnesia-derived autos have become as terpene and effect donors. For example, breeders seeking big terp profiles have turned to Amnesia-based autos to spice up new lines; one publicized path described leveraging Strawberry Amnesia Auto specifically for its rich terpene payload in a modern hybrid project. This trend aligns with the reality that Amnesia-type autos often test with above-average terpinolene and limonene, making them ideal for elevating aroma in subsequent crosses. Amnesia Auto’s impact is visible in how frequently it appears as a parent or benchmark in new autoflowering releases.
You can also see Amnesia Auto’s broad footprint in the way resources, knowledge bases, and seed catalogs index Amnesia variants. Site maps and strain directories routinely list multiple Amnesia autos and CBD-forward expressions—entries like Amnesia Auto CBD, Amnesia Bilbo, and Amnesia Bilbo Autoflowering reflect the lineage’s spread across formats. This breadth signals strong demand for the recognizable Amnesia effect profile across diverse use cases, from recreational focus to calmer, CBD-modulated experiences. Kera’s Amnesia Auto sits squarely in this ecosystem as a faithful, fast version of a classic.
The project philosophy behind Amnesia Auto is pragmatic: deliver sativa brightness in climates and schedules where full-season Hazes struggle. Breeders typically select for rapid floral initiation (day-neutrality), moderate internodal spacing, and a terpene stack that survives ruderalis introgression. Each generation focuses on reconciling texture and resin production with predictable finish times. Growers benefit from a cultivar that can thrive under long daily photoperiods—18/6 or 20/4—and still ripen on schedule.
Genetic Lineage and Botany
Amnesia Auto’s heritage is a composite of ruderalis, indica, and sativa, with sativa-led traits dominating the chemotype and effect profile. The ruderalis component confers autoflowering behavior, enabling flowering independent of day length. Indica ancestry tightens bud structure, moderates stretch, and can bolster resin output for better bag appeal. The sativa portion drives the classic Amnesia signature: a bright, citrus-forward, terpinolene-dominant nose and a soaring cerebral lift.
From a botanical perspective, Amnesia Auto tends to express medium internodal spacing and slightly elongated calyxes, true to its Haze roots. Leaf morphology is typically hybridized—narrow blades compared to broadleaf indicas, but not as needle-like as pure tropical sativas. Pistil color transitions from white to orange-amber late in flower, often with high pistil density early. Trichome coverage is abundant by week 7–8 from seed, reaching peak cloudiness near harvest.
Autoflowering physiology changes how growers interact with the plant. Instead of triggering bloom via a 12/12 schedule, Amnesia Auto will declare pre-flowers around days 18–28 from sprout and enter full bloom by weeks 4–5. This compressed lifecycle means less room for high-stress training or recovery from major errors. The plant rewards consistent, gentle care with a balanced canopy and consistent finish windows.
Appearance and Morphology
Amnesia Auto typically matures at 60–120 cm indoors, depending on container size, light intensity, and phenotype. Outdoor plants in temperate climates commonly reach 80–130 cm when started early and kept well-fed. The structure is moderately open, allowing better airflow than dense indica autos, which contributes to mold resistance in humid locales. Buds form as stacked, tapered spears with modest foxtailing possible under high heat or intense PPFD.
Calyxes are medium-sized, with a tendency to swell during the final 10–14 days as trichomes turn cloudy. You’ll observe a shimmering blanket of glandular trichomes across sugar leaves, often producing a frosted look by week 8. Pistils begin bright white, then age to tangerine and eventually a subdued rust tone near full maturity. Mature bracts can show subtle lime-to-emerald hues that pop against orange pistils and silver trichomes.
The canopy is responsive to gentle shaping. With light low-stress training (LST), you can create a shallow, multi-branch structure that evens out colas and improves light penetration. Stems lignify adequately to hold midweight flowers, but stakes or soft ties help in high-wind outdoor settings. Overall, the morphology blends sativa elegance with autoflower practicality.
Aroma and Bouquet
The bouquet is dominated by citrus-zest brightness layered over incense, pine, and faint herbal sweetness. On first rub, many growers note lemon peel, pink grapefruit, and a classic Haze incense that hints at cedar and sandalwood. Secondary aromas include sweet melon, fresh-cut herbs, and light earthiness—a reminder of the ruderalis contribution and the cultivar’s hybrid nature. The overall effect is clean, invigorating, and unmistakably Amnesia.
During flowering, aroma intensifies markedly after week 7, correlating with a surge in monoterpene production. Limonene adds sparkling citrus while terpinolene delivers that airy, effervescent top note that many associate with classic Dutch coffeeshop sativas. Beta-caryophyllene brings a peppery undertone, especially noticeable when flowers are agitated. In sealed environments, carbon filters are recommended once resin heads begin to cloud.
Cured flowers reveal a more complex incense-and-wood spine. Faint floral hints—lilac and orange blossom—can appear in the background of well-cured batches. As the cure progresses from week 2 to week 6, volatile top notes mellow slightly, allowing deeper cedar, tea, and honeyed herb nuances to emerge. The bouquet remains bright but gains polish and cohesiveness over time.
Flavor and Mouthfeel
The flavor profile mirrors the nose but leans even more citrus-forward on the inhale. Expect lemon-lime soda with a crisp pine bite and a trailing haze of herbal incense. On the exhale, peppery caryophyllene and subtle anise can appear, followed by a lingering grapefruit pith bitterness that cleanses the palate. Vaporization at 175–185°C accentuates the floral and citrus layers while keeping the wood and spice in balance.
Combustion reveals a slightly richer, resinous mouthfeel, with cedar and herbal tea tones becoming more pronounced. Many users describe the smoke as clean and bright, with minimal harshness in well-flushed, slow-dried samples. A proper cure—10–14 days of drying and 3–8 weeks of curing—significantly improves smoothness and brings forward honeyed citrus sweetness. In edibles, the citrus-peel note translates to a zesty, pleasant finish without overwhelming baked goods.
Terp-wise, the palate is consistent with a terpinolene-limonene emphasis. Terpinolene contributes the spritzy, green-citrus sparkle, while limonene layers tangy lemon and slight sweetness. Myrcene softens edges and introduces mild herbal depth, and ocimene adds a fresh, green snap. The total package tastes like a modern, refined take on classic Haze.
Cannabinoid Profile and Potency
Modern autoflower breeding has pushed potency into territory once reserved for photoperiods, and Amnesia Auto is a beneficiary of that progress. Typical lab results for comparable Amnesia-based autos fall in the 16–21% THC range, with standout phenotypes occasionally testing slightly higher under optimal conditions. CBD is usually low, commonly between 0.1–0.8%, maintaining a decidedly THC-forward chemotype. Minor cannabinoids like CBG often register 0.2–1.0%, while THCV is usually present only in trace amounts (<0.2%).
Such a profile maps closely to the experiential feedback reported by consumers: fast onset, vivid cerebral activation, and a clear ceiling where stimulation can flip into raciness if overdosed. Inhaled onset tends to occur within 2–5 minutes, peaking around 30–45 minutes, and tapering over 2–3 hours. Vaporization yields a slightly cleaner arc with fewer combustion byproducts and often a more nuanced sense of clarity. Edible formulations extend duration to 4–6 hours but shift the character toward a heavier body feel as 11-hydroxy-THC predominates.
From a cultivation standpoint, environment and harvest timing can shift potency by several points. High light intensity (800–1,000 µmol/m²/s PPFD in bloom), consistent root-zone oxygenation, and stable temperatures (24–28°C day, 20–22°C night) tend to improve cannabinoid synthesis. Harvesting at 5–15% amber trichomes generally preserves the bright, energetic quality while maximizing THC. Waiting for heavy amber tends to mellow the effect and may reduce perceived peak stimulation.
Terpene Profile and Aromachemistry
Amnesia Auto commonly expresses a terpinolene-dominant or terpinolene-limonene co-dominant terpene profile, consistent with its Amnesia/Haze ancestry. In well-grown samples, total terpene content often falls between 1.2–2.5% of dry weight, with exceptional phenotypes edging higher. Terpinolene typically ranges from 0.4–0.9%, limonene from 0.15–0.5%, and myrcene from 0.2–0.6%. Beta-caryophyllene and ocimene often each contribute 0.1–0.3%, while linalool appears in smaller amounts (0.03–0.10%).
Terpinolene is associated with fresh, zesty, and slightly woody fragrances that read as “sparkling” to the nose. Limonene layers bright citrus and is frequently linked in user reports with mood elevation and perceived stress relief. Beta-caryophyllene is unique as a dietary cannabinoid-terpene that can engage CB2 receptors, potentially contributing to anti-inflammatory effects. Myrcene and ocimene modulate the bouquet with herbal depth and green, slightly sweet freshness.
The stability of terpene expression improves with careful post-harvest handling. Drying at 18–21°C and 55–60% RH for 10–14 days preserves monoterpenes better than fast, warm dries. Airtight curing (with periodic burping) in the 58–62% RH range retains the delicate top notes that define Amnesia’s signature. Over-drying below 55% RH can flatten the profile, muting limonene and terpinolene disproportionately.
In the wider market, Amnesia-derived autos are prized for their terpene density relative to lifecycle length. Breeders repeatedly harness this trait to elevate the aroma in derivative projects. Notably, autos with Amnesia ancestry have been selected as terpene donors in new crosses where both speed and a complex citrus-incense nose are required. This aligns with observations that terp-rich autos can rival photoperiods when correctly cultivated and cured.
Experiential Effects and User Reports
Users consistently describe Amnesia Auto as energizing, clear-headed, and mood-lifting, especially in the first 60–90 minutes post-inhalation. The early phase features sharpened focus, brighter colors, and a mild to moderate euphoria that remains functional for most consumers. Creative tasks, socializing, and light outdoor activities pair well with this arc. As the peak settles, many report a comfortable body lightness without heavy sedation.
Dose and tolerance shape the experience significantly. At low to moderate doses (e.g., 5–15 mg THC inhaled estimate), Amnesia Auto is typically uplifting and mentally organized. Above that, some sensitive users may experience raciness or transient anxiety, a pattern common with terpinolene-forward sativas. Hydration, slow titration, and mindful setting can reduce the risk of over-stimulation.
Anecdotal duration runs around 2–3 hours for inhalation and 4–6 hours for edibles, with residual afterglow stretching a bit longer. Vaporized sessions tend to feel cleaner with less throat fatigue and a more present citrus-herbal aftertaste. Music, brainstorming, photography walks, or tidy creative tasks often get a boost during the middle of the arc. As with many sativa-leaning cultivars, late-night use can delay sleep for some people.
Side effects follow the well-known THC pattern: dry mouth and dry eyes are common, and transient appetite increase can occur after the peak. Rapid heart rate or a brief anxious wave can appear at high doses or in unfamiliar settings. Starting low, especially for new users, is the best strategy to ensure the enjoyable, bright side of the experience. Many seasoned consumers find Amnesia Auto to be a reliable daytime companion when dosed thoughtfully.
Potential Medical Applications
While formal clinical data specific to Amnesia Auto are limited, its chemotype suggests several plausible therapeutic use cases. The THC-forward profile and limonene-terpinolene emphasis align with user reports of mood elevation and reduced perceived stress. For some, this translates to short-term relief of low mood or situational anxiety, though individuals prone to THC-induced anxiety should proceed cautiously. The generally clear, functional mindset may also be useful for addressing fatigue or motivational dips.
Beta-caryophyllene’s engagement of CB2 receptors adds a theoretical anti-inflammatory and analgesic dimension. Patients with mild neuropathic discomfort or inflammatory pain sometimes report benefit, particularly when dosing remains moderate to avoid counterproductive stimulation. Myrcene’s presence, even at modest levels, can slightly soften the experience and may contribute to muscle relaxation later in the arc. Together, these constituents offer a multifaceted effect that some medical users find adaptable across daytime scenarios.
Appetite modulation is another potential avenue, albeit less pronounced than with heavier indica chemovars. Users occasionally note a gentle appetite nudge during the comedown, which could support those managing mild appetite loss. Nausea relief, a common THC-linked benefit, has been reported anecdotally in contexts such as motion-related queasiness or medication-induced nausea. Vaporized delivery is often preferred for faster onset and titration control.
Cognitive and mood-related support is where Amnesia Auto may shine for certain individuals. Creative engagement, focus during routine tasks, and a perceived lifting of mental fog are recurring themes in user narratives. However, those with a history of anxiety disorders or panic should evaluate tolerance carefully, as stimulating terpenes coupled with higher THC can be a double-edged sword. Medical guidance and low-and-slow experimentation are prudent.
As always, responses vary widely by individual physiology, tolerance, and context. Patients should consult healthcare providers, especially when combining cannabis with existing medications or conditions. Product testing, consistent dosing, and attention to setting will help users find a stable therapeutic window. Documentation of effects in a personal log can further optimize outcomes over time.
Comprehensive Cultivation Guide
Lifecycle and timing
Amnesia Auto typically runs 70–85 days from seed to harvest indoors, with some phenotypes completing closer to 90–95 days under cooler or lower-light conditions. Pre-flowers often appear by days 18–28, and full bloom follows by weeks 4–5. Because autos do not rely on 12/12 to flower, you can maintain an 18/6 or 20/4 light schedule throughout. Consistency is key; avoiding major stress in the first four weeks pays big dividends at harvest.
Environment and climate
Aim for daytime temperatures of 24–28°C and nighttime 20–22°C, with relative humidity around 55–65% in early growth. Reduce RH to 40–50% in mid-flower and 35–40% in late flower to minimize botrytis risk. Vigor improves with stable VPD; target roughly 0.8–1.2 kPa during veg and 1.2–1.5 kPa in bloom. Good airflow—oscillating fans and steady extraction—keeps the microclimate uniform and fragrant but manageable.
Lighting and intensity
Amnesia Auto responds well to modern LEDs. For seedlings, 300–450 µmol/m²/s PPFD prevents stretch without stress; in veg, 600–800 PPFD drives strong growth; in bloom, 800–1,000 PPFD is a sweet spot for density. Daily Light Integral (DLI) in the 35–45 mol/m²/day range is often sufficient for autos without CO2 supplementation. If enriching CO2 to ~1,000–1,200 ppm, you can push PPFD toward 1,100–1,200, provided temp and nutrition rise proportionally.
Mediums and containers
Soilless mixes (coco coir with 20–30% perlite) promote rapid root development and allow precise feeding. Living soil growers can succeed with a lightly amended, well-aerated mix, top-dressing as needed. Container sizes of 11 L (3 gal) are common for small spaces; 15–19 L (4–5 gal) support larger phenotypes without excessive height. Transplant only once or start in final pots to avoid growth stalls in autos.
pH, EC, and feeding
In coco, maintain pH 5.8–6.2; in soil, 6.2–6.8. Early veg EC of 1.0–1.3 mS/cm rises to 1.4–1.8 mS/cm in mid-flower and up to ~2.0 mS/cm for heavy feeders if leaves remain healthy. Nitrogen should be moderate in early bloom to avoid excess leaf growth; shift emphasis to phosphorus and potassium as buds stack. Calcium and magnesium supplementation is often beneficial under LEDs; 0.5–1.0 ml/L of a Cal-Mag product or equivalent can prevent interveinal chlorosis and tip burn.
Watering and root health
Autos prefer a gentle, frequent irrigation pattern that keeps the root zone oxygenated. In coco, watering once or twice daily to 10–20% runoff prevents salt accumulation and keeps EC stable. In soil, water thoroughly and allow the top 2–3 cm to dry before repeating; avoid chronic saturation to prevent pythium. Root inoculants (mycorrhizae, Trichoderma) at transplant can improve nutrient uptake and stress tolerance.
Training and canopy management
Keep training low-stress, especially before day 25–28. Bending and tying branches to open the canopy works well, while topping is best reserved for vigorous phenos and only if done very early (around node 3 and before day 20). A light defoliation to remove large fan leaves that cast deep shade can help prevent humidity pockets. Avoid heavy stripping that autos may not have time to recover from.
Nutrition strategy by week (generalized)
Weeks 1–2: Mild feed (EC 0.8–1.1), focus on root development with balanced NPK and micronutrients. Keep RH 60–65% and PPFD modest.
Weeks 3–4: Increase EC to 1.2–1.4 as rapid vegetative growth peaks and pre-flower appears; begin light bloom boosters only as pistils emerge.
Weeks 5–7: Bloom stack; EC 1.5–1.8, reduce N slightly, raise K to support turgor and terpene synthesis; monitor for Mg/Ca demand under strong LEDs.
Weeks 8–10+: Maintain bloom feed as needed; consider gentle taper or flush 7–10 days before harvest in soil and 3–7 days in coco, depending on leaf status and accumulated salts.
Pest and disease management
The open, sativa-leaning structure of Amnesia Auto helps airflow, but dense mid-colas can still trap moisture. Preventive IPM is best: yellow sticky traps for fungus gnats, beneficial nematodes for larvae, and careful watering practices. For foliar pathogens, employ biologicals like Bacillus amyloliquefaciens or Bacillus subtilis during veg, and sulfur (if used) only well before bloom to avoid residue and terpene impact. Keep intake air filtered and quarantine new plants or clones when applicable.
Outdoor cultivation
Outdoors, plant after the last frost and aim for 10–12 weeks of stable weather. In full sun, expect plants 80–130 cm tall with 60–150 g per plant under average conditions; rich soil and mid-summer timing can push higher. Use fabric pots for better root aeration and temperature control. Watch late-season humidity and morning dew; light pruning and staking keep colas upright and drier.
Yield expectations
Indoors, experienced growers under quality LEDs can achieve 350–500 g/m² with 8–12 plants per m² in 11–15 L pots. Single-plant yields often range 60–120 g in 3–5 gallon containers, scaling with canopy management and intensity. CO2, dialed PPFD, and impeccable environment can lift yields beyond these baselines. As always, phenotype variance and grower technique heavily influence outcomes.
Harvest timing and trichomes
Begin checking trichomes from day 60 onward under magnification. For a bright, energetic profile, many growers harvest at mostly cloudy with ~5–10% amber. For a slightly calmer finish, wait for 10–20% amber. Watch pistil recession and calyx swell as complementary cues rather than relying solely on calendar days.
Drying and curing
Dry in 18–21°C and 55–60% RH with gentle airflow for 10–14 days. Stems should snap, not bend, when ready for trimming and jarred curing. Cure in airtight containers at 58–62% RH, burping daily for the first week, then weekly. A 3–8 week cure markedly improves smoothness and crystallizes the Amnesia citrus-incense personality.
Common pitfalls and fixes
Overfeeding nitrogen in early bloom can delay flower set and promote excess leaf mass—dial N back as pistils initiate. Heavy defoliation after week 4 can stall autos; opt for gradual, selective leaf removal. Cold nights below ~17°C can stunt growth and mute terpenes, while heat above 30°C can drive foxtailing and terpene volatilization—tighten environmental control accordingly. If runoff EC climbs steadily, reset with a light flush and resume balanced feeding to restore uptake.
Scent control and post-harvest handling
Amnesia Auto develops a pronounced aroma by week 7; properly sized carbon filters and sealed ducting prevent leaks. Avoid drying too quickly; monoterpenes that define the citrus-topper are volatile and easily lost. Minimize handling during trimming to protect trichome heads—consider a hybrid wet-dry trim approach depending on humidity. Store finished flower in dark, cool conditions to slow terpene and cannabinoid degradation.
Scaling and automation
Autos benefit from stability, making them excellent candidates for automated irrigation in coco or rockwool. Utilize moisture sensors or consistent manual rhythms to avoid the feast-famine cycles that stress autos. In multi-plant runs, staggered sowing by 7–10 days can smooth workflow from transplant to harvest. Keep records of phenotypes, feeding, and environment to refine future cycles of Amnesia Auto.
Context in Modern Breeding and Market Presence
Amnesia-based autos are widely leveraged in contemporary breeding for their distinctive citrus-incense top notes and brisk, motivating effects. A publicized example includes the choice of Strawberry Amnesia Auto as a terpene-rich, autoflower gene donor in a modern hybrid project, showcasing how Amnesia-line autos can elevate aroma in new creations. This pattern mirrors broader market behavior where breeders tap into familiar, proven noses to anchor novel crosses. Aroma consistency, speed, and user recognition make Amnesia autos strategic building blocks.
Market catalogs and educational portals routinely list multiple Amnesia derivatives, including autoflowering and CBD-modulated versions. Site indexes that enumerate entries such as Amnesia Auto CBD, Amnesia Bilbo, and Amnesia Bilbo Autoflowering highlight the lineage’s adaptability across chemotypes and target audiences. Such breadth signals sustained consumer demand for the mental clarity and citrus-forward character that Amnesia is known for. Kera Seeds’ Amnesia Auto fits into this continuum as a faithful, fast, and potent representative.
For growers and users, this presence translates to better access to region-appropriate options—short-season autos for cooler climates, higher-CBD variations for gentler effects, and terp-forward crosses for connoisseurs. The cross-pollination between auto and photoperiod programs continues to compress the historical performance gap. As analytical labs and breeders iterate, we can expect even tighter potency ranges and more repeatable terpene stacks in Amnesia Auto lines. The net effect is a more predictable experience backed by data-driven selection.
