Auto Amnesia by Divine Seeds is an autoflowering hybrid that merges ruderalis, indica, and sativa genetics to deliver the signature Amnesia uplift in a compact, fast-finishing format. Typical seed-to-harvest time ranges from 75 to 90 days, making it suitable for growers in short-season climates and for indoor cultivators seeking multiple harvests per year. Plants commonly reach 60 to 120 cm indoors, with trained specimens staying on the shorter side without compromising canopy coverage. Yield potential is competitive for an auto, with experienced growers reporting 350 to 550 g per square meter indoors and 60 to 180 g per plant in outdoor containers under favorable conditions.
Potency is generally medium to high for an autoflower, with total THC frequently testing between 15 and 22 percent depending on phenotype, environment, and nutrient management. CBD levels are usually low, often between 0.1 and 0.8 percent, while minor cannabinoids such as CBG can reach 0.2 to 1.0 percent. The terpene profile leans toward the classic Haze bouquet, dominated by terpinolene, myrcene, limonene, and beta-caryophyllene in many lab-tested samples of Amnesia-derived autos. Expect bright citrus, sweet herbal wood, and a crisp, incense-like top note that intensifies when the flower is properly cured.
Other seedmakers reinforce the strain family’s reputation for speed and volume, lending external context to Divine Seeds’ Auto Amnesia. Advanced Seeds markets a version named Auto Amnesia XXL, emphasizing large yields with minimal fuss. Pyramid Seeds highlights very fast growth and approachability for less experienced growers in its Auto Amnesia Gold, noting that even novice cultivators can succeed. These third-party points align with the core promise of Auto Amnesia genetics: quick harvests, high resin output, and a clean, cerebral experience anchored by Haze terpenes.
History of Auto Amnesia
Amnesia as a family traces back to Dutch breeding circles of the late 1990s and early 2000s, where Haze hybrids were selected for their soaring cerebral effects and layered citrus-incense aroma. The original photoperiod Amnesia lines became staples in European coffeeshops and competitions, with numerous cuts and seed versions circulating under Amnesia and Amnesia Haze labels. As autoflowering breeding matured in the 2010s, breeders worked to capture the iconic Amnesia profile in shorter, photoperiod-independent plants. This required careful backcrossing to stabilize the Haze-forward terpene spectrum while incorporating the flowering trigger from Cannabis ruderalis.
Divine Seeds entered this space by developing an Auto Amnesia tailored to variable climates, consistent with the breeder’s broader focus on hardy, practical cultivars. The company’s approach typically emphasizes robust seedling vigor and resilience, qualities that are valuable when translating a finicky sativa-leaning profile into an autoflower format. Across Europe, the success of auto Amnesia variants popularized the concept that a heady, creative sativa effect does not have to be constrained by long flowering times. This opened the door for growers with limited seasons or space to experience the Amnesia signature without the long, lanky growth of classic Hazes.
The rise of Auto Amnesia also mirrors the broader shift in home cultivation, where autos have grown from a niche to a mainstream choice. Short cycles allow two to four indoor runs per year in the same space, a major efficiency gain compared to 10 to 14 week photoperiod Hazes. Outdoor hobbyists at high latitudes also benefit because a July sowing can still finish by late September, beating early autumn rains. This combination of flexibility and a premium flavor-effect profile explains why Auto Amnesia remains a perennial listing on seed menus.
Genetic Lineage and Breeding Rationale
Auto Amnesia combines three broad genetic inputs: sativa-dominant Haze ancestry for flavor and head effect, indica influence for structure and resin density, and ruderalis to ensure autoflowering. In most plants, the sativa component is expressed as longer internodes early in growth, high leaf-air exchange rates, and a preference for moderate EC levels during bloom. Indica traits tend to tighten bud structure and shorten maturation windows, often raising the calyx-to-leaf ratio compared to pure Hazes. Ruderalis contributes the day-length independence and a predictable transition to flowering around the fourth week.
Although percentages vary by phenotype, many Amnesia autos behave like a 60 to 70 percent sativa, 20 to 30 percent indica, and 10 to 20 percent ruderalis composite. This blend balances a tall, airy architecture with adequate stem strength for indoor environments and light training. The ruderalis input also confers resilience against mild temperature swings, a valuable trait for balcony or greenhouse grows. Successful breeding stabilizes the chemotype while preventing excessive stretch, a common pitfall when sativa-leading autos are rushed to market.
In practice, modern Auto Amnesia lines are the result of multi-generational selection and recurrent crossing. Breeders track traits such as days to preflower, internodal spacing, apical dominance, and terpene ratios, culling outliers that drift away from the Amnesia signature. Lab testing during selection helps verify THC consistency and maintain the desired terpinolene-forward profile. The end result is a cultivar that tastes and feels like Amnesia, yet behaves like a disciplined auto in the tent.
Appearance and Plant Morphology
Auto Amnesia typically grows with a central cola and several satellite spears if left untrained, reaching 60 to 120 cm indoors under an 18-hour light schedule. Internodes are medium length early and shorten as the plant transitions into bloom, creating a layered stack of golf ball to soda-can buds. The canopy generally shows a lighter lime to medium green, with leaves slightly narrower than pure indica autos. Many growers report a calyx-forward structure that makes trim work straightforward.
Mature flowers are often coated in a thick trichome layer, with bulbous heads that express well under macro photography. Pistils start off pale and can range to orange and copper by the final weeks; in cooler nights, some phenotypes develop faint lavender hues at the sugar-leaf tips. The resin output is noteworthy for an auto, and sticky fingers during harvest are common. Resin-rich bracts tend to swell late, so plants can visually transform in the last 10 days.
Root systems are vigorous when given adequate container volume, often filling 11 to 18 liter pots with a dense fibrous network. A strong root mass supports rapid uptake in mid-bloom, when daily water demand can rise to 5 to 8 percent of container volume. Stems are flexible rather than woody, allowing gentle low-stress training without breakage. This morphology suits compact indoor setups that favor even, flat canopies.
Aroma and Flavor
The aroma of Auto Amnesia leans classic Haze, with bright citrus top notes, sweet herbal wood, and a clean, almost minty incense as flowers cure. Freshly ground buds often release terpinolene-dominant tones reminiscent of pine and green apple, supported by limonene’s lemon zest and a peppery caryophyllene edge. Myrcene contributes a soft, slightly earthy sweetness that rounds out the bouquet. During late flower, rubbing the sugar leaves brings out a resinous, sweet-spice character.
Flavor follows aroma closely, delivering a brisk citrus inhale and an herbal, woody exhale with hints of cedar and basil. Vaporization between 180 and 195 Celsius tends to highlight the brighter terpenes and preserve the cleaner, heady finish. When combusted, the smoke is typically smooth if cured for two to three weeks at 60 to 62 percent relative humidity. A slow cure intensifies the incense note and can deepen perceived sweetness.
Compared to heavier Kush or Cookies profiles, Auto Amnesia feels lighter and cleaner on the palate, with less lingering fuel and more forest-citrus lift. The flavor performs well in joints and convection vaporizers where airflow and temperature control allow the terpenes to bloom. Proper storage at 16 to 21 Celsius and 58 to 62 percent relative humidity helps preserve the top-note brightness for three months or more. Beyond that window, oxidation gradually dulls the citrus edge and pushes the profile toward herbal wood.
Cannabinoid Profile and Potency
Auto Amnesia commonly tests in the mid to high teens for THC, with many indoor-grown samples landing between 15 and 22 percent. This equates to roughly 150 to 220 milligrams of THC per gram of dried flower, acknowledging that moisture content and lab methodology introduce natural variance. CBD is typically low, often measured between 0.1 and 0.8 percent, while CBG can appear in the 0.2 to 1.0 percent range. Total cannabinoids frequently exceed 16 to 23 percent when all minors are included.
For inhalation, onset is rapid, typically within 1 to 5 minutes, with peak subjective effects arriving at 10 to 30 minutes. The main experience persists for 2 to 4 hours for most consumers, depending on dose, tolerance, and individual metabolism. When prepared as an edible, 10 milligrams of THC feels notably stronger and longer lasting than the same amount inhaled, with onset in 30 to 120 minutes and a duration of 4 to 8 hours. Due to the sativa-leading nature of Auto Amnesia, higher doses are more likely to feel stimulating rather than sedating.
Grow conditions can shift potency by several percentage points, making environment and nutrition significant factors. In controlled rooms with 600 to 900 micromoles per square meter per second of PPFD and stable VPD, well-fed plants consistently reach the upper potency band. Overfeeding nitrogen late or allowing excessive heat can depress total THC by 1 to 3 percentage points. Proper harvest timing tied to trichome maturity preserves the chemotype and avoids degradation of THC into CBN.
Terpene Profile and Aromatics
Across Amnesia-derived autos, total terpene content often ranges from 1.0 to 2.5 percent by dry weight when grown and cured carefully. Terpinolene is frequently dominant in the Amnesia family, appearing in the 0.2 to 0.8 percent range in well-expressed phenotypes. Supporting terpenes commonly include myrcene at 0.2 to 0.6 percent, limonene at 0.1 to 0.4 percent, and beta-caryophyllene at 0.1 to 0.3 percent. Secondary contributors like ocimene, alpha-pinene, and linalool may register between 0.05 and 0.2 percent each.
This terpene mix frames the sensory experience by providing high-tone citrus, green apple, pine, and sweet wood, with a peppery spice underpinning. Terpinolene’s airy, botanical character is central to the impression of cleanliness and mental clarity many users associate with Haze lines. Limonene elevates perceived brightness and mood, while caryophyllene adds grounding spice and interacts with CB2 receptors. Myrcene can subtly soften the edges without muting the top notes.
Because terpene expression is environmentally sensitive, cultivation practices directly impact results. Cooler night temperatures during late flower and a careful cure at 60 to 62 percent relative humidity help retain monoterpenes that would otherwise volatilize. Minimal handling during trimming and airtight storage limit oxidative loss. These steps preserve the crisp, incense-citrus identity that defines Auto Amnesia’s appeal.
Experiential Effects, Onset, and Duration
Auto Amnesia is celebrated for an energetic, head-forward experience that arrives quickly and clears the mental cobwebs. Many users describe a clean lift, improved focus, and a buoyant mood in the first 20 minutes. Creative tasks, casual conversation, and light outdoor activities often pair well with the effect profile. Relative to indica-leaning autos, this cultivar is less likely to bring heavy body sedation at moderate doses.
As the session continues, a gentle euphoria builds without a heavy crash for most consumers. The strain can be stimulating, and sensitive individuals may feel racy at higher doses, especially with THC above 20 percent. A measured approach is wise; two to three small inhalations commonly provide a comfortable plateau for new users. The primary effects taper after 2 to 3 hours, with residual clarity sometimes lasting longer.
Side effects are typical of THC-dominant cannabis. Dry mouth and dry eyes are common and can be managed by hydration and eye drops. Overconsumption may lead to anxiety or jitters, especially in crowded or unfamiliar settings. Those prone to such reactions should start low, favor vaporization, and pair with calming activities to smooth the experience.
Potential Medical Applications
While medical outcomes vary and should be discussed with a clinician, Auto Amnesia’s profile suggests utility for certain daytime needs. The uplifting, fast-onset effect may support people seeking to boost motivation and counter fatigue during the day. The strain’s focus and clarity can be conducive to creative work or task switching, which some users find helpful for attention-related challenges. The low CBD content means it is not tailored for conditions that respond best to CBD-forward ratios.
Terpinolene and limonene are frequently associated with bright mood and alertness, which aligns with many Auto Amnesia user reports. Beta-caryophyllene’s interaction with CB2 receptors can contribute a subtle anti-inflammatory edge, although the effect is usually overshadowed by THC in this chemotype. Some patients with migraine or tension-type headaches report benefit from stimulating sativa-leaning chemovars, but triggers are individual, and close self-monitoring is essential. For anxiety-prone patients, a gentler THC dose or a CBD companion product may be advisable.
Given the stimulating nature of the effects, evening use may impact sleep onset for some individuals. Patients prioritizing appetite stimulation can respond variably; Amnesia lines can either modestly increase or leave appetite unchanged compared to heavier indica chemotypes. A practical approach is to titrate dose in small increments, track timing and symptoms in a journal, and maintain consistent product and method for two weeks before drawing conclusions. Professional guidance helps align expectations with the pharmacology of a THC-dominant, terpinolene-forward cultivar.
Comprehensive Cultivation Guide: Planning, Media, Containers, and Lighting
Auto Amnesia thrives in a well-lit, well-aerated environment with moderate nutrient strength. Indoors, aim for 18 hours of light per day throughout the cycle, delivering 600 to 900 micromoles per square meter per second of PPFD in mid to late bloom. A daily light integral between 35 and 45 mol per square meter is a practical target for autos without supplemental CO2. If boosting CO2 to 900 to 1200 ppm, PPFD can be increased toward 900 to 1000 to match the added carbon.
Container size influences final plant size and yield. For indoor soil or coco, 11 to 18 liter pots balance root volume and floor space; outdoors, 20 to 30 liters give headroom for heat and wind. An airy medium helps autos avoid early stress; a simple blend is 60 percent high-quality coco or light soil, 30 percent perlite or pumice, and 10 percent worm castings. Maintain media pH at 5.8 to 6.2 for coco and 6.2 to 6.6 for soil during the bulk of the cycle.
Nutrient strength should remain modest compared to photoperiods. In coco, target EC around 1.0 to 1.2 during early growth, 1.4 to 1.6 in mid flower, and up to 1.7 to 1.8 at peak demand if leaves remain healthy. In soil, feed by runoff every second or third watering, watching tips and leaf color to avoid overfeeding. Cal-mag supplementation of 100 to 150 ppm Ca and 30 to 50 ppm Mg is helpful under high-intensity LEDs.
Comprehensive Cultivation Guide: Germination, Early Growth, and Training Strategy
Germinate seeds using a 24-hour soak followed by the paper towel method until the taproot reaches 0.5 to 1.0 cm, then plant 1 to 1.5 cm deep into the final container. Autos dislike transplant shock, so sowing directly into the final pot minimizes delays. Maintain a warm, humid environment at 24 to 26 Celsius and 65 to 75 percent relative humidity for the first 10 days. Gentle air movement encourages sturdy stems without desiccating seedlings.
By days 10 to 14, growth accelerates, and preflowers may appear as early as days 18 to 25. Avoid topping beyond day 14 to 20, as autos have limited time to recover; instead, practice low-stress training by bending the main stem and securing lateral branches to open the canopy. Removing one or two large fan leaves that shade key bud sites is acceptable, but aggressive defoliation can stall growth. The goal is even light distribution without stunting.
Watering discipline is crucial. In coco, daily fertigation at 10 to 20 percent runoff once roots fill the pot supports rapid development. In soil, water when the top 2 to 3 cm are dry, aiming for full container saturation and then allowing a moderate dryback. Overwatering in early life is the most common cause of underperformance in autos.
Comprehensive Cultivation Guide: Environment Control, Flowering Management, and IPM
Keep daytime temperatures between 24 and 27 Celsius in veg and 22 to 26 Celsius in bloom, with lights-off no lower than 18 to 20. Relative humidity should step down from 65 to 75 percent in seedling stage to 55 to 65 percent in early bloom and 45 to 55 percent in late bloom. This tracks a VPD of roughly 0.8 to 1.2 kPa early and 1.2 to 1.5 kPa late, encouraging transpiration without excessive stress. Maintain strong air exchange, with total room air turnover at least once per minute in small tents.
Flowering typically initiates on its own around days 21 to 30, and stretch continues for 10 to 20 days after pistils first appear. Increase phosphorus and potassium during this window and temper nitrogen to avoid lush, soft growth that invites pests. Keep PPFD closer to 700 to 800 during early stretch, then increase to 800 to 900 as flowers set, provided leaves remain perky and green. If leaves taco or bleach, back off intensity by 5 to 10 percent and reassess.
Integrated pest management should begin before pests are seen. Yellow sticky traps monitor flying insects such as fungus gnats and whiteflies; beneficial microbes like Bacillus subtilis and Trichoderma in the root zone reinforce disease resistance. Neem or horticultural oils can be used during early veg for prophylaxis; switch to microbials or biological controls as buds form. Good sanitation, filtered intakes, and quarantining new plants are the highest-leverage defenses against mites and mildew.
Comprehensive Cultivation Guide: Harvest Timing, Drying, and Curing
Auto Amnesia generally finishes between days 75 and 90 from sprout, though faster phenotypes can conclude around day 70 under ideal conditions. For a balanced head-to-body effect, harvest when trichomes are mostly cloudy with 5 to 10 percent amber and minimal clear heads. This window preserves the bright terpene profile and avoids a sedative tilt that can come with higher amber percentages. Use a jeweler’s loupe or macro lens to confirm resin maturity across multiple buds.
Drying parameters make or break the final quality. Aim for 18 to 20 Celsius and 55 to 60 percent relative humidity with gentle airflow and darkness, targeting a 10 to 14 day dry. Branches should bend before snapping when ready for trim and jar. Faster dries push chlorophyll forward and dull the incense-citrus top notes.
For curing, jar at 62 percent RH using humidity control packs and burp daily for the first week, then every few days for weeks two and three. A three to four week cure polishes the flavor and brings the aroma into sharp focus, often increasing perceived sweetness. Store jars in a cool, dark place; every 10 Celsius reduction roughly halves the rate of terpene oxidation. Under proper storage, terpenes remain vibrant for several months.
Yield Expectations, Plant Size, and Benchmarks
With diligent culture, indoor yields of 350 to 550 g per square meter are attainable using 600 to 900 micromoles per square meter per second of PPFD and an 18-hour day. Single-plant yields in 11 to 18 liter containers often fall between 50 and 120 g, with outliers exceeding 150 g under high-intensity lighting and dialed-in fertigation. Outdoor balcony or garden plants can produce 60 to 180 g per plant in 20 to 30 liter pots, contingent on sunlight hours and temperature stability. These figures align with the reputation of the Amnesia auto family for robust production.
Height at harvest typically lands between 60 and 120 cm indoors, depending on pot size, light intensity, and training. Low-stress training can flatten the canopy and expand footprint without increasing height. Stretch ratios of 1.5 to 2.5 times the preflower height are common, so planning for vertical headroom prevents late-stage crowding. A trellis or soft ties can tame enthusiastic tops during the peak stretch window.
Independent seedmakers provide contextual benchmarks for the class. Advanced Seeds positions its Auto Amnesia XXL as a large-yielding option, aligning with upper-range g per square meter expectations under strong light. Pyramid Seeds markets Auto Amnesia Gold as very fast and novice-friendly, which dovetails with the shorter end of the 70 to 90 day finish window. These external signals reinforce the expectations for Divine Seeds’ Auto Amnesia when given proper care.
Comparisons to Photoperiod Amnesia and Other Autos
Compared to photoperiod Amnesia or Amnesia Haze, the auto version finishes significantly faster and is easier to manage in confined spaces. Photoperiod Hazes can require 10 to 14 weeks of flowering alone, with total cycle times extending beyond five months from seed. Auto Amnesia compresses this to roughly 11 to 13 weeks total while keeping much of the bright citrus-incense identity. The tradeoff is a slightly lower ceiling on potency and yield per plant compared to large, long-trained photoperiods.
Versus indica-leaning autos, Auto Amnesia offers a more cerebral and active experience with less body sedation. Terpene composition differs, with terpinolene and limonene taking the lead rather than myrcene-dominant or fuel-heavy profiles. Growers will notice taller structure, more pronounced stretch, and a stronger response to canopy management. For consumers, the mouthfeel is lighter and the aftertaste cleaner.
Within the broader market of auto Hazes, phenotypic variation is normal. Some plants lean fruitier with more limonene and ocimene, while others push a drier, incense-forward tone with elevated terpinolene. Breeder selection reduces but does not eliminate this spread, so planting two to three seeds improves the odds of finding a personal favorite. Cloning autos is possible but inefficient, so repeated seed runs remain the practical route.
Consumer Guidance, Dosing, and Storage
For first-time users, start with one or two small inhalations and wait 10 minutes to assess potency, especially with THC near or above 20 percent. Regular consumers often find two to four inhalations sufficient for daytime function without overshooting into raciness. Edible formulation requires modest dosing due to the longer and stronger effect arc; 2.5 to 5 milligrams can be a better starter range than 10 milligrams for those new to THC. Spacing sessions and staying hydrated reduce the likelihood of side effects.
To preserve quality, store flower in airtight glass at 58 to 62 percent relative humidity and 16 to 21 Celsius. Avoid light exposure, which accelerates terpene loss and THC degradation to CBN. Ground material stales faster; grind only what you need for a session. Under these practices, Auto Amnesia retains much of its bright aroma for three months, with gradual softening thereafter.
Device choice influences flavor and effect perception. Convection vaporizers accentuate high-tone terpenes and can make the experience feel cleaner and more controlled. Joints and clean glass provide a traditional feel but can mute subtle citrus notes at higher combustion temperatures. Regardless of method, a slow and mindful approach showcases the cultivar’s clarity.
Breeder Context and Live Information Integration
Divine Seeds positions Auto Amnesia as a resilient, fast auto that captures the uplifting spirit of Amnesia within a practical grower’s timeframe. The genetic heritage is a three-way ruderalis, indica, and sativa mix, chosen to harmonize Haze expression with dependable autoflowering and compact stature. This aligns with Divine Seeds’ focus on robust plants suited to a range of latitudes and skill levels. The result is a cultivar that rewards both careful indoor dialing and hands-off outdoor runs.
Market peers help triangulate expectations around speed and yield within the Amnesia auto category. Advanced Seeds promotes Auto Amnesia XXL as a high-yield interpretation, signaling that the Amnesia auto architecture can push g per square meter to the upper band when lighting and nutrition are optimized. Pyramid Seeds describes Auto Amnesia Gold as very fast and friendly for less experienced growers, underscoring the category’s accessibility without sacrificing flavor. These signals echo the lived experiences of gardeners who value quick turnarounds and bright, energizing profiles.
Taken together, the Divine Seeds entry aims to deliver the core Amnesia experience with minimal barriers to entry. The sativa-forward aroma and effect ride atop a surprisingly forgiving growth habit for a Haze-leaning plant. For cultivators seeking a first foray into auto Hazes, this is a logical starting point. For veterans, it is a productive, terpene-rich staple that slots neatly into perpetual schedules.
