Auto Amnesia is a sativa-dominant autoflowering cultivar developed by CBD Seeds, designed to deliver the cerebral brightness of classic Amnesia in a compact, day‑neutral format. As a ruderalis/sativa hybrid, it transitions from seed to harvest without any changes in photoperiod, making it highly accessible to growers working indoors or at higher latitudes. The aim is straightforward: preserve the electric, incense‑and‑citrus character of Amnesia while shortening the lifecycle and simplifying cultivation.
Among autoflowers, Auto Amnesia stands out for its head‑focused uplift, its zesty, Haze‑leaning aroma, and its capacity to produce dense, resin‑rich colas despite a smaller frame. Growers commonly see a full cycle in about 10–12 weeks, though environment and phenotype can push timelines slightly shorter or longer. In consumer feedback, its effects skew clear and energetic rather than sedative, aligning closely with its sativa lineage.
The strain is commonly sold in feminized autoflowering seed format by multiple breeders, enabling predictable gardens even for newcomers. CBD Seeds’ work seeded a broader family of Amnesia autos across the market, with several houses showcasing their own expressions of the profile. For the end user, that translates to a consistent theme—bright, uplifting sativa—delivered on a dependable autoflowering schedule.
Because Auto Amnesia bridges the gap between legendary flavor and modern convenience, it’s become a go‑to in personal gardens and micro‑grows. Its architecture supports tight spaces, and the cultivar responds well to moderate training when timed correctly. The result is a high‑energy cultivar that respects your calendar while still rewarding your palate.
Origins and Breeder History
CBD Seeds is credited with bringing Auto Amnesia to market, combining established Amnesia genetics with carefully selected ruderalis donors. This move responded to a rising demand in the late 2000s and early 2010s for faster, more discreet plants that still delivered recognizable flavor and potency. Early autoflowers were sometimes criticized for muted terpene intensity, but CBD Seeds and peers improved aromatic density through iterative selection.
As the autoflower segment matured, other breeders released their interpretations. Advanced Seeds markets an Auto Amnesia XXL variant emphasizing high production potential and ease of access, positioning it for growers chasing larger yields per square meter. Pyramid Seeds’ Auto Amnesia Gold focuses on fast growth and a superb sativa taste, explicitly signaling grower‑friendliness for those with less experience.
These parallel offerings illustrate how the Amnesia auto concept diversified while retaining its core identity. Each house emphasizes slightly different goals—yield, speed, flavor intensity—but all orbit the same Haze‑inspired experience. For consumers, this means you can choose an expression that matches your priorities without abandoning the hallmark Amnesia spark.
The broader arc of autoflowers also set the stage for Auto Amnesia’s popularity. Since the first stable day‑neutral cultivars in the early 2000s, autos have gained traction for their calendar certainty and stealth. Auto Amnesia fits that trajectory, bringing a classic European sativa profile to growers who need results in three months or less.
Genetic Lineage and Breeding Rationale
At its core, Auto Amnesia fuses Amnesia—an umbrella name tied to Haze‑dominant sativa hybrids—with Cannabis ruderalis selected for day‑neutral flowering. The ruderalis component contributes the autoflowering trait, which is recessive and requires careful breeding to fix in progeny. Breeders typically perform multiple filial generations and backcrosses to stabilize the trait while recovering as much of the Amnesia flavor and effect as possible.
From a Mendelian standpoint, crossing a photoperiod Amnesia with an autoflower donor produces F1s that are usually photoperiod, carrying the day‑neutral allele. Selfing or intercrossing F1s can produce F2s with approximately 25% autoflowering individuals, which are then selected and inbred to fix the trait. Subsequent generations focus on recovering terpene density and cannabinoid potency that can be diluted in early ruderalis crosses.
Breeding goals target several linked traits: day‑neutrality, sativa‑leaning effect, terpene fidelity to Haze‑style citrus and incense, and improved bud structure. The sativa fraction preserves tall internodes and a soaring high, while selection works to compact the plant to a manageable indoor form. Over time, breeders balance internode spacing, resin output, and flowering speed to deliver a reliable home‑grow performer.
Because Amnesia itself is a family of related lines rather than a single clone, expressions of Auto Amnesia can vary in minor ways. Some phenotypes lean sharper and citric, while others push a spicier, woody incense. The ruderalis donor also shapes vigor and timing, contributing to the 10–12‑week seed‑to‑harvest window typical for this cultivar.
Morphology and Visual Appearance
Auto Amnesia shows a compact‑medium stature, commonly reaching 70–120 cm indoors when grown under adequate light. Plants exhibit sativa‑leaning leaflets—slender, serrated, and elongated—but the overall structure is more compact than a full photoperiod Haze. Internodal spacing is moderate at roughly 5–8 cm, allowing light penetration without sacrificing cola density.
During early bloom, spear‑shaped colas stack along the main stem and upper branches, often forming a central top with several satellite spears. Calyces swell and fox‑tail modestly as maturation advances, a trait seen in many sativa‑dominant autos. Trichome coverage is generous, frosting bracts and sugar leaves with a silvery sheen that intensifies near harvest.
Coloration runs from lime to medium green, with occasional golden pistils that darken to amber as the crop ripens. Cooler nighttime temperatures can lend faint purple hues to sugar leaves, though this is phenotype‑ and environment‑dependent. In ideal conditions, bract‑to‑leaf ratio is favorable, easing trim work while retaining sticky resin.
Stem vigor is a notable trait, supporting the weight of developing colas without excessive staking. That said, soft plant ties or a single vertical support for the main cola can help in late bloom. Overall, the cultivar balances sativa expression with autoflower practicality, keeping size manageable without looking squat.
Aroma and Flavor Profile
The nose opens with bright lemon and sweet citrus, quickly joined by classic Haze incense—woody, floral, and slightly peppered. Beneath that top note lies a resinous herb tone, often described as eucalyptus or bay leaf in subtle traces. When broken up, buds release a sharper zest and a faint, sweet anise that lingers in the grinder.
On inhalation, the flavor mirrors the aroma with clean citrus and a silky herbal glide. The exhale leans spicier, delivering pepper, cedar, and a lingering, almost mentholated freshness. Many users report a dry, mouth‑coating incense aftertaste that’s emblematic of Amnesia‑type sativas.
Vaporizing at lower temperatures accentuates the terpinolene‑limonene brightness and a delicate floral sweetness. Combustion brings deeper caryophyllene spice and a toasted wood character, especially in the final third of a joint. In concentrates, the profile shifts toward sharper lemon‑pine with a persistent, perfumed haze.
Overall intensity is medium‑high for an autoflower when grown well and cured thoroughly. A 3–6 week cure in stable conditions brings out the sweeter edges and rounds off green, grassy notes. This maturation step often transforms the bouquet from simply citrusy to complex and incense‑laden.
Cannabinoid Profile and Potency Statistics
Auto Amnesia is bred for sativa‑style potency, with most breeder reports placing THC in the mid to high teens and sometimes above 20% under optimal conditions. Across the market, Amnesia‑leaning autos are commonly listed between 15–22% THC, though real‑world outcomes vary with environment, feeding, and harvest timing. CBD content tends to be low, often below 1%, keeping the psychoactive profile firmly THC‑forward.
Minor cannabinoids can be present in modest amounts, with CBG frequently detected in the 0.2–1.0% range. CBC and THCV may appear in trace levels, contributing subtly to the energizing feel. Total cannabinoids in well‑grown autoflowers typically land around 18–24% by dry weight, considering resin saturation and plant physiology.
Autoflowers historically trailed photoperiods in maximum potency, but the gap has narrowed considerably with modern breeding. Proper light intensity, balanced nutrition, and a disciplined harvest window can push potency to the top of published ranges. Conversely, stress events and under‑lighting can pull results down into the low‑mid teens.
Growers should interpret advertised THC percentages as best‑case scenarios rather than guarantees. Lab variance, testing protocol differences, and sample selection all influence numbers. The most reliable predictor of potency is environment consistency and the grower’s control over maturation cues.
Terpene Profile and Chemical Nuance
Auto Amnesia commonly expresses a terpinolene‑leading profile, with limonene, myrcene, and beta‑caryophyllene contributing prominently. In independent lab reports for sativa‑leaning autos, total terpene content often ranges between 1.0–2.5% by dry weight when cultivation is optimized. Within that, terpinolene is frequently observed around 0.3–0.8%, limonene 0.2–0.6%, myrcene 0.2–0.5%, and beta‑caryophyllene 0.2–0.4%.
Secondary terpenes like ocimene, linalool, humulene, and alpha‑pinene appear in trace‑to‑moderate amounts depending on phenotype and cure. These compounds collectively sculpt the citrus‑incense aroma, with limonene amplifying zest and caryophyllene layering spice. Myrcene adds a subtle herbal sweetness that rounds out sharper edges.
Terpinolene’s presence aligns with the energetic, effusive feel often attributed to Amnesia lines. While terpenes do not act in isolation, their ratios can correlate with subjective effects. Higher limonene batches are often described as brighter and mood‑lifting, whereas more caryophyllene‑rich expressions feel slightly warmer and spicier.
Cultivation practices materially impact terpene outcomes. Lower drying temperatures, extended curing, and minimal late flower stress generally preserve more volatile compounds. Conversely, high heat, rapid dry‑downs, or over‑ripeness can mute the top notes that define this cultivar.
Experiential Effects and Consumer Reports
Consumers most often describe Auto Amnesia as clear, cerebral, and uplifting within 5–15 minutes of consumption. The onset typically builds over the first 20–30 minutes, with peak intensity between 45 and 90 minutes. Many report enhanced focus and an extroverted, talkative mood that pairs well with creative tasks and daylight activities.
Body sensation tends to be light and mobile rather than heavy or sedative. The headspace can feel expansive, occasionally bordering on racy in high doses or for individuals sensitive to THC. As such, new consumers often benefit from conservative dosing—one or two draws—before ramping up.
Duration of noticeable effect frequently spans 2–3 hours for inhaled routes, tapering to a clean, non‑groggy finish. Edible preparations extend the timeline significantly, but may also amplify heart‑rate sensitivity common to bright sativas. Hydration and a nutrient‑dense snack can help maintain comfort during peak effects.
The overall tone is social and active for most users, with music, outdoor walks, and brainstorming sessions reported as favorable pairings. Those prone to anxiety should favor lower doses and calm environments to appreciate the cultivar’s clarity without overstimulation. Tolerance, set, and setting remain powerful variables in shaping the experience.
Potential Medical Uses and Considerations
Anecdotally, Auto Amnesia’s energizing profile is sought by individuals looking to combat daytime fatigue and low mood. Some users report short‑term relief from stress, situational blues, and creative blocks due to the cultivar’s upbeat and focusing qualities. The limonene‑forward bouquet may contribute to perceived mood elevation, though individual responses vary widely.
The cultivar’s clear head and low body weight can make it attractive for tasks requiring light movement without heaviness. A portion of consumers note benefits for appetite activation around mealtimes, especially with inhaled use before lunch. Others indicate it supports social engagement by reducing inhibitions in small group settings.
Caveats are important with potent sativa‑leaning THC profiles. Individuals with a history of panic or THC sensitivity may experience jitteriness at higher doses, particularly with concentrates. Starting low and titrating slowly is a prudent approach.
Nothing in this article constitutes medical advice, and cannabinoid therapy should be discussed with a qualified clinician where appropriate. Legal access, product consistency, and personal health history all influence outcomes. When in doubt, seek professional guidance and maintain a consumption journal to track what works for you.
Cultivation Guide: Planning, Setup, and Germination
Successful Auto Amnesia grows begin with planning for a 10–12 week seed‑to‑harvest cycle. Autoflowers do not wait for a 12/12 flip, so any early stress meaningfully impacts final size and yield. Choose a container that supports uninterrupted growth from day one, such as 11–15 liter (3–4 gallon) fabric pots for indoor runs.
Germination success rates over 90% are common with proper technique. Use the paper towel or direct‑seed method into pre‑moistened, lightly fertilized media at 24–26°C and 70–80% RH. Avoid soaking seeds beyond 18–24 hours to reduce the risk of oxygen deprivation.
Soilless blends of coco coir and perlite (70/30) or light, aerated soils work well for autos due to rapid root development. Aim for a gentle starter EC of 0.6–0.9 mS/cm with a pH of 5.8–6.2 for coco and 6.2–6.8 for soil. A microbial inoculant—mycorrhizae plus beneficial bacteria—can improve vigor and nutrient uptake.
Plan your light schedule in advance, as consistency is vital. Most growers favor 18/6 or 20/4 from sprout to harvest; both schedules work, with 20/4 sometimes providing a slight growth edge. Keep the light intensity modest during the first 7–10 days to prevent stress, then ramp carefully.
Cultivation Guide: Environment, Nutrition, and Lighting
Target daytime temperatures of 24–28°C and nighttime 18–22°C for steady growth. Relative humidity should start high and taper: 65–70% for seedlings, 55–60% for early vegetative growth, 45–50% for early flower, and 40–45% for late flower. This RH progression maintains a vapor pressure deficit near 0.9–1.2 kPa, supporting transpiration without inviting pathogens.
Under modern LEDs, Auto Amnesia responds well to 500–700 µmol/m²/s PPFD in early growth and 700–900 µmol/m²/s in bloom. That corresponds roughly to a daily light integral (DLI) of 35–45 mol/m²/day at 18–20 hours. Maintain 30–45 cm of fixture distance for mid‑power bar LEDs, adjusting by cultivar response and leaf edge curl cues.
Nutrition should be balanced and slightly conservative during weeks 1–3. Increase EC to 1.1–1.6 mS/cm after day 10 and to 1.6–2.0 mS/cm as pistils proliferate. Keep nitrogen moderate in early bloom to avoid leafy buds, and front‑load calcium and magnesium for LED environments.
Irrigation should be frequent but not saturating in the seedling phase, moving to full‑volume, 10–20% runoff events in coco once roots fill the container. Allow light drybacks in soil to support oxygenation and avoid root rot. Consistent pH—5.8–6.0 for coco and 6.3–6.6 for soil—is crucial to avoid micronutrient lockout.
Cultivation Guide: Training, Irrigation, and Plant Health
Autoflowers are time‑sensitive, so training must be gentle and early. Low‑stress training (LST) from day 12–21 is ideal, pulling the main stem laterally to open the canopy and promote multiple tops. Topping is possible for experienced growers if done once at the 3rd–4th node by day 18–20, but skipping it eliminates risk.
Selective defoliation can improve airflow, but keep leaf removal conservative—no more than 10–15% in a single session, especially in week 4–6. Removing large solar panels too aggressively can stunt an auto during its critical stretch phase. Tuck rather than cut where possible to preserve photosynthetic area.
Maintain steady irrigation cadence tuned to pot size and stage. In coco, daily or twice‑daily feeds with 10–20% runoff are common in mid‑late bloom. In soil, water thoroughly to full pot saturation, then wait for the top 2–3 cm to dry before the next event.
Adopt an integrated pest management program from day one. Sticky cards, weekly leaf inspections, and preventative sprays with neem or rosemary‑based products in early veg help avoid outbreaks. Cease oil‑based sprays once buds form to protect trichome integrity and flavor.
Cultivation Guide: Flowering, Harvest, Drying, and Curing
Auto Amnesia typically declares flower by day 20–28, with visible pistils and a rapid stretch through week 5–6. Total seed‑to‑harvest time commonly falls between 70 and 85 days in optimized indoor conditions. Phenotypes with more pronounced sativa expression may extend to 90 days, especially under cooler nights.
Begin bloom support by raising potassium, phosphorus, and micronutrients while moderating nitrogen. Supplement calcium and magnesium through week 7–8 to prevent mid‑flower deficiencies, particularly under high‑intensity LEDs. Keep airflow robust to manage transpiration and prevent botrytis in denser colas.
Harvest timing is best guided by trichome observation rather than day counts. For a bright, classic Amnesia feel, many growers target mostly cloudy trichomes with 5–10% amber. That window often coincides with peak terpene expression and a brisk, non‑sedating finish.
Dry at 18–20°C and 55–60% RH for 10–14 days to keep chlorophyll breakdown slow and aroma intact. After a gentle manicure, cure in airtight containers at 58–62% RH, burping daily for the first week and then weekly for 3–6 weeks. Well‑cured flowers show a marked increase in incense‑citrus complexity and a smoother throat feel.
Yield Expectations, Phenotypes, and Breeder Variants
Indoors, Auto Amnesia commonly yields 350–500 g/m² under dialed‑in LED lighting, with experienced growers and high‑efficiency spaces pushing higher. Single plants in 11–15 liter pots often produce 60–120 g, depending on training and environment. Outdoors, individual yields of 70–180 g per plant are typical in temperate summers with at least 12–14 weeks of frost‑free weather.
Advanced Seeds offers an Auto Amnesia XXL, explicitly highlighting large yield potential and ease of cultivation. Such XXL expressions can surpass 500 g/m² in optimized conditions, reflecting a selection bias toward production traits. By contrast, Pyramid Seeds’ Auto Amnesia Gold emphasizes very fast growth and superb sativa flavor, appealing to less experienced growers who value speed and taste.
Phenotypic spread within Auto Amnesia lines is moderate, as expected for stabilized autos. You may see a smaller pheno around 70–80 cm and a taller sister reaching 110–120 cm, with corresponding differences in cola length. Flavor can shift from lemon‑dominant to incense‑woody emphasis depending on terpene balance.
Consistency improves with controlled environments, gentle training, and tight nutrient management. Avoid transplant shock and late pruning, which can exaggerate size differences. Selecting seeds from reputable lots and storing them cool and dry preserves vigor and uniformity.
