Amnesia Ganja Haze Auto is an autoflowering hybrid bred by Sumo Seeds, designed to capture the electrifying clarity of classic Haze lines in a compact, fast-cycle package. As an auto, it relies on Cannabis ruderalis genetics to flower by age rather than day length, blending that trait with indica and sativa influences for a ruderalis/indica/sativa heritage. This structure makes it accessible for small spaces and shorter seasons while still delivering the cerebral kick associated with Amnesia-type profiles.
Autoflower aficionados gravitate to this cultivar for its seed-to-harvest timeline that commonly falls between 70 and 85 days under optimal indoor conditions. Compared to photoperiod Hazes that may take 10 to 14 weeks of flowering alone, Amnesia Ganja Haze Auto compresses the entire life cycle without discarding the uplifting experience. In practice, this rebalancing tends to produce a more manageable plant with a terpene profile that leans bright, citrusy, and incense-like.
Across community grow logs and breeder-facing descriptions, the strain is characterized as medium in stature with an assertive main cola and satellite spears. Indoor yields typically range from 350 to 500 grams per square meter with high-intensity lighting, while outdoor or balcony plants often return 40 to 120 grams per plant depending on latitude and season length. The combination of speed, vigor, and an energizing effect profile has helped it gain traction among both novice and experienced growers seeking Haze energy without Haze-level patience.
History and Breeding Origins
Sumo Seeds, a European breeder known for translating classic Dutch and international genetics into practical, grower-friendly formats, developed Amnesia Ganja Haze Auto to deliver a recognizable Haze experience in an autoflowering chassis. The automatic flowering trait is inherited from ruderalis stock, a subspecies that evolved in high-latitude regions where long summer days favored age-triggered, rather than darkness-triggered, bloom onset. By pairing this with Haze-influenced parentage, Sumo Seeds created a seed line capable of finishing in under three months while still offering a complex terpene bouquet.
The strain’s name signals its goal: anchor on the Amnesia family’s euphoric and crisp sativa expression while adding the ganja-forward resin and haze-style aromatics. Historically, Amnesia-type cultivars in Europe have been mainstays of coffee shops due to their head-forward effects and citrus-incense aroma. Translating that profile into an auto required careful selector work to maintain terpene fidelity and cannabinoid potency under the constraints of ruderalis dominance.
Autoflower breeding has matured significantly since the 2000s, when early autos suffered from low potency and sparse yields. Over the last decade, breeders like Sumo Seeds have consistently closed that performance gap, with modern autos routinely testing in the mid to high teens and often surpassing 20% total THC in optimized runs. Amnesia Ganja Haze Auto represents this new generation, balancing potency, speed, and flavor in a way that reflects the broader evolution of the autoflower category.
In practice, the cultivar has been adopted in regions where short summers challenge photoperiod Hazes. Northern growers in latitudes 50 to 60 degrees report completing cycles mid-summer, avoiding late-season moisture and mold pressure. This strategic timing is part of the appeal, and it has carved out a stable niche for the auto variant even in markets saturated with photoperiod Amnesia phenotypes.
Genetic Lineage and Heritage
Amnesia Ganja Haze Auto carries a ruderalis/indica/sativa heritage, with ruderalis lending the automatic flowering trait that initiates bloom based on age rather than photoperiod. The sativa component draws from Haze influences, known for a terpene ensemble led by terpinolene, limonene, and pinene that deliver citrus, pine, and incense. Indica input helps tighten internodal spacing, improve yield density, and shorten the overall life cycle.
In broad strokes, Haze-derived autos often target a genetic balance around 60 to 70% sativa influence in effect while retaining roughly 20 to 30% indica structure traits and 10 to 20% ruderalis functionality. While exact ratios can vary by phenotype, this framework helps explain the cultivar’s tall cola, lateral branching, and tendency toward an energetic, clear-headed effect. Growers commonly note that the plant looks sativa-leaning above the soil line but behaves like a well-tuned auto below it, moving decisively from seedling to early bloom.
Ruderalis input can reduce cannabinoid ceilings in weaker crosses, but in modern autos the effect is often attenuated by backcrossing and selection. Sumo Seeds’ implementation typically maintains a THC range competitive with photoperiod hybrids, while the indica backbone supports resin production and mechanical resilience. The net result is a hybridized lineage that feels like an Amnesia experience delivered through a compact, timely, and grower-friendly lens.
Appearance and Morphology
Amnesia Ganja Haze Auto tends to present a pronounced apical dominance, forming a main spear-shaped cola flanked by secondary branches that create a conical canopy. Internodes are moderately spaced, often landing in the 4 to 7 centimeter range under strong indoor lighting, which helps stack floral clusters without inviting dense, mold-prone congestion. Leaf morphology skews narrow to medium-width blades, signaling the sativa influence while retaining just enough indica breadth for robust photosynthesis.
Height is generally manageable, with most indoor plants finishing between 60 and 110 centimeters when grown in 7 to 11 liter containers. Outdoor plants in full sun may stretch slightly taller, sometimes reaching 120 centimeters, especially if started early and fed generously. This stature aligns well with tent cultivation, allowing enough vertical room for 30 to 45 centimeters of lamp clearance during late flower.
Bud structure is elongated and tapering rather than golf-ball dense, typical of Haze-influenced autos. Calyxes swell notably in the final two weeks, with papery, lime-to-forest green bracts and amber-to-reddish pistils as maturity approaches. Trichome coverage is pronounced for an auto, with a frosty sheen that becomes obvious by day 45 to 55, signaling active cannabinoid and terpene production.
Stems are flexible but sturdy, tolerating gentle low-stress training and leaf tucking without complaint. Lateral branches can carry weight, though light trellising or a soft tie on the main cola improves posture during the final swell. Because the cultivar moves quickly, early canopy management in the first 3 weeks is crucial to set the plant’s long-term structure.
Aroma and Bouquet
The aromatic signature revolves around a bright, zesty top end backed by classic Haze incense. Many growers describe a lemon-lime opening enriched by sweet orange rind, followed by a peppery, herbal undertone as flowers mature. Crushed sugar leaves can reveal pine needle freshness alongside faint floral nuances reminiscent of jasmine or lilac.
As flowers ripen, the bouquet intensifies, often exhibiting a terpinolene-forward profile that smells clean, crisp, and slightly woody. Caryophyllene and humulene contribute a pepper-balsam depth, preventing the aroma from reading as purely citrus. In jars, the nose can evolve from effervescent citrus to a slightly sweet, musky haze with a dry, cedar-like echo.
Drying method has a measurable impact on volatile retention, with slow drying at 18 to 20 degrees Celsius and 55 to 60% relative humidity preserving monoterpenes better than fast, warm dry rooms. Growers who dry over 7 to 10 days frequently report a stronger limonene and terpinolene signature compared to speed-dried batches. Proper curing then layers in complexity, highlighting the herbal-spicy interplay typical of Amnesia-style aromatics.
Flavor and Palate
On the palate, Amnesia Ganja Haze Auto mirrors its aroma with a citrus-forward attack followed by spice and resin. The first impression often lands as lemon peel and sweet lime soda, transitioning to black pepper, basil, and a faint clove aftertaste on the exhale. In vapor, the profile feels cleaner and greener, with pine and eucalyptus tones easier to spot.
Combustion tends to accentuate the pepper and incense side while adding a toasted herbal note. When properly flushed and cured, the smoke is smooth and lightly sweet, with a drying sensation on the tongue that suggests a caryophyllene-humulene presence. Resin content can leave a lingering citrus-oil feel on the lips after a few draws.
Terpene preservation correlates strongly with cure conditions; jars held at 58 to 62% relative humidity often maintain better citrus brightness. Many users note the flavor remains stable for 60 to 90 days post-cure before slowly mellowing into a softer, woodier haze. Storing at 15 to 18 degrees Celsius in the dark helps retain the top notes for a longer window.
Cannabinoid Profile
As a modern autoflower, Amnesia Ganja Haze Auto typically lands in a THC range that is competitive with photoperiod hybrids. Grower reports and European dispensary menus commonly place it between 16 and 21% total THC when cultivated under high-intensity lighting and optimal nutrition. Under suboptimal conditions, autos can trend lower, and a practical band of 12 to 15% is not uncommon in low-light or nutrient-stressed runs.
CBD content in Haze-derived autos is usually minimal, often below 1%, with total CBD frequently measured at 0.1 to 0.6%. This low CBD environment contributes to the bright, stimulating character, as there is less CBD-mediated modulation of the THC experience. Minor cannabinoids, such as CBG, can appear in trace amounts, often in the 0.2 to 1.0% range, adding subtle support to the entourage effect.
Environmental control plays a significant role in dialing potency. Maintaining daily light integral in the 35 to 45 mol per square meter per day range and leaf-surface VPD near 1.0 to 1.3 kilopascals during peak bloom can improve resin output. Similarly, balanced nutrition with a late-flower emphasis on potassium and micronutrients supports secondary metabolite synthesis, which often correlates with stronger test results.
Terpene Profile
Haze-descended autos frequently express a terpinolene-dominant profile, and Amnesia Ganja Haze Auto commonly aligns with that pattern. In third-party analyses of Haze-forward autos, terpinolene often comprises 20 to 35% of the measured terpene fraction, with limonene and alpha-pinene each filling 5 to 12% bands. Beta-caryophyllene and humulene collectively may contribute 12 to 20%, providing the peppery, balsamic floor beneath the citrus-wood nose.
Myrcene is usually present at moderate levels despite the sativa-forward identity, often ranging from 8 to 18% of the terpene fraction in comparative haze-type datasets. This supports a slightly sweet, herbal undertone without steering the profile into heavy, musky territory. Ocimene, linalool, and nerolidol appear in smaller amounts, adding floral and tropical flickers that become more obvious in vapor than smoke.
Terpene expression is sensitive to drying conditions and light intensity during late flower. Monoterpenes like terpinolene and limonene volatilize readily above 22 degrees Celsius, and dry rooms held in the 18 to 20 degree window can preserve 10 to 20% more volatiles compared to hotter environments. Supplementing with gentle UV-A and limited UV-B in the final two weeks is a technique many growers use to nudge resin density and aromatic intensity, provided leaf temperatures are carefully managed to prevent stress.
A practical takeaway is to harvest based on trichome maturity while scent is peaking rather than simply counting days. If the room smells vividly of citrus and incense and trichomes are mostly cloudy, you are likely at a terpene apex. Pulling slightly earlier often preserves the brightest top notes, while a later harvest deepens spice and wood tones at the cost of some lift.
Experiential Effects
The experiential arc typically begins with a swift, clear mental lift, often noticeable within 5 to 10 minutes when inhaled. Users report heightened focus, a light pressure around the temples, and an uplifted mood that fits daytime tasks or creative sessions. The headspace is energetic but not frantic when dosed moderately, aligning with the motivational character many seek from Amnesia-type cultivars.
As the session continues, body lightness and gentle muscle ease arrive without heavy couchlock. Indica influence shows up more as physical calm than sedation, and many describe an ease of movement that pairs well with music, conversation, or light exercise. At higher doses, the cerebral component can become racy, so beginners should start with small quantities and build carefully.
Duration varies by route, but inhalation effects commonly last 2 to 3 hours with a clean taper. Vaporization at moderate temperatures between 175 and 190 degrees Celsius often yields a brighter, more functional headspace, while combustion can add a warmer, dreamier tone as the session progresses. Terpene balance also plays a role, with terpinolene-forward batches feeling airier and limonene-rich jars delivering a sunnier, mood-elevating push.
Socially, this cultivar tends to be conversational and outward facing. Many users find it conducive to brainstorming, journaling, or collaborative creative work, especially when kept to micro-to-moderate doses. For evening use, those sensitive to stimulatory head highs might prefer pairing with a heavier strain or stepping down intake to avoid late-night alertness.
Potential Medical Uses
While formal clinical data specific to this cultivar are limited, the broader profile of Haze-leaning, THC-dominant hybrids provides guidance for potential applications. Users self-report mood elevation and mental activation that may help with low motivation or mild depressive states. The strain’s clear focus can be beneficial for tasks requiring attention, though those with anxiety should approach cautiously due to the energizing headspace.
In the physical domain, light muscle relaxation and perceived reduction in tension are common, which some users leverage for daytime relief of minor aches or stress-related tightness. The relatively low CBD content means this is not a classic analgesic heavy hitter, but the entourage of terpinolene, limonene, and caryophyllene can create a balanced sense of well-being. Individuals seeking anti-inflammatory support sometimes cite caryophyllene’s CB2 receptor activity as a plus, even in modest concentrations.
Appetite stimulation is moderate compared to indica-dominant cultivars, but many users still note a gentle increase after 30 to 60 minutes. For nausea, fast-acting inhalation can deliver fairly quick relief in sensitive populations, though results vary by individual tolerance and trigger. Those with a sensitivity to stimulating terpene profiles may prefer a lower-temperature vaporization range to minimize raciness.
As always, patient-specific responses differ, and medical use should consider individual history and consultation with a healthcare professional. People prone to anxiety, panic, or tachycardia should start very low, as THC-forward Hazes can amplify those concerns at high doses. For daytime functional relief, microdosing strategies of 1 to 3 small inhalations often achieve benefits without tipping into overstimulation.
Cultivation Guide: Environment and Germination
Amnesia Ganja Haze Auto benefits from a controlled indoor environment with stable temperature, humidity, and airflow. Aim for 24 to 28 degrees Celsius during the day and 20 to 23 degrees at night, keeping leaf-surface vapor pressure deficit near 0.8 to 1.2 kilopascals in early growth and 1.0 to 1.3 kilopascals in bloom. Relative humidity targets of 65 to 70% for seedlings, 55 to 60% for early veg, and 45 to 55% for late flower strike a good balance between growth rate and mold prevention.
Seed germination rates for reputable autos often exceed 90% when executed correctly. The paper towel or rapid rooter method at 24 to 26 degrees Celsius promotes fast radicle emergence, typically within 24 to 72 hours. Once the taproot is visible, transplant promptly into the final container to avoid transplant shock, which can significantly reduce final yield in autos.
Container size influences overall plant size and yield; 7 to 11 liters indoors is a strong sweet spot for this cultivar. Outdoors, 15 to 25 liters can unlock additional root volume and biomass where space permits. Using a light, well-aerated medium with 20 to 30% perlite or pumice supports aggressive autoflower root expansion and oxygenation.
Soil pH should be maintained around 6.2 to 6.8, while soilless and hydroponic systems perform well at 5.7 to 6.2. Electrical conductivity can start at 0.6 to 0.8 in early growth, rising to 1.2 to 1.6 in mid-veg and 1.6 to 1.8 peak bloom for most phenotypes. Overfeeding early autos is a common mistake; ramp slowly, watch leaf tips for burn, and let the plant’s posture guide increases.
Cultivation Guide: Training, Nutrition and Irrigation
Because autos transition to flower by age, training must be gentle and early. Low-stress training from day 10 to 21, using soft plant ties to arc the main stem and open the canopy, can increase top exposure without stalling growth. Avoid topping unless you are experienced and the plant shows vigorous early growth; a single topping at the fifth node by day 18 to 21 can work, but many growers prefer only LST for reliability.
Defoliation should be minimal and targeted. Removing 2 to 4 large fan leaves that directly block bud sites around day 25 to 35 can improve light penetration without shocking the plant. Continuous leaf tucking is preferred over aggressive stripping, as excessive defoliation can slow an auto enough to knock yields down by 10 to 25%.
Nutritionally, autos generally prefer moderate feeding, and Amnesia Ganja Haze Auto follows that rule. A balanced vegetative NPK around 3-1-2 or 2-1-2, transitioning in bloom to 1-2-3 or 1-3-2 depending on product line, supports steady growth. Calcium and magnesium are crucial under high-intensity LEDs; supplementing 100 to 150 ppm calcium and 40 to 60 ppm magnesium often prevents interveinal chlorosis and leaf curl.
Irrigation volume should equal roughly 10 to 20% of container volume per watering, adjusted to plant size and media drainage. Let the top 2 to 3 centimeters of media dry between events to maintain aerobic conditions and encourage root hunting. Drip irrigation with 2 to 4 daily pulses during peak bloom helps stabilize EC, reduces salt spikes, and maintains consistent nutrient delivery.
Cultivation Guide: Light Strategy and Photobiology
Autos thrive under long photoperiods, and Amnesia Ganja Haze Auto performs well at 18 to 20 hours of light throughout the entire cycle. Daily light integral targets of 35 to 45 mol per square meter per day are achievable with 600 to 900 micromoles per square meter per second PPFD for 18 hours, depending on fixture efficiency. If power costs are a concern, a 20 on and 4 off schedule can be dialed down to 18 on and 6 off with only a minor yield penalty when PPFD is optimized.
LEDs with a full spectrum biased toward 3000 to 4000 Kelvin CCT, plus supplemental 660 nanometer deep red, drive robust photosynthesis and flower formation. Adding 1 to 2 watts per square meter of UV-A and cautious, low-intensity UV-B in the last 10 to 14 days can modestly increase trichome density. Keep leaf-surface temperatures 2 to 3 degrees Celsius warmer under LEDs than under HPS to maintain metabolic rates, as LEDs produce less radiant heat.
CO2 enrichment to 900 to 1200 ppm under PPFD above 800 can increase biomass by 10 to 20% in well-tuned rooms. Without sufficient light and nutrition, added CO2 offers little benefit and can even complicate humidity and heat management. Always integrate CO2 with precise environmental control rather than as a stand-alone fix.
Cultivation Guide: Pest, Disease and IPM
Preventive integrated pest management is critical for fast autos because there’s little time to recover from infestations. Begin with strict hygiene, quarantining new clones or plants and keeping the grow area free of debris, standing water, and unfiltered intakes. Sticky cards placed at canopy and pot height help detect early pressure from fungus gnats, whiteflies, and thrips.
Biological controls can be deployed proactively. Bacillus thuringiensis israelensis drenches suppress fungus gnat larvae, while predatory mites like Amblyseius cucumeris and Amblyseius swirskii can reduce thrips and whitefly populations. For spider mites, Neoseiulus californicus and Phytoseiulus persimilis are effective options when introduced early and supported by suitable humidity.
Powdery mildew and botrytis are the primary disease concerns in dense colas. Maintain late-flower humidity below 55% and ensure continuous air movement with 0.3 to 0.6 meters per second across the canopy. Prune interior fluff, avoid overhead watering, and consider beneficial sprays like potassium bicarbonate or biological fungicides in veg as a preventive measure, stopping all foliar sprays by early flower to protect buds.
Harvest, Drying, Curing and Storage
Most phenotypes of Amnesia Ganja Haze Auto are ready to harvest between day 70 and 85 from sprout, though environmental factors can shift this window by a week. Trichome monitoring is the most reliable method: aim for 5 to 10% clear, 75 to 85% cloudy, and 10 to 20% amber for a balanced head-body effect. Those seeking maximum clarity may harvest with fewer amber heads, while a slightly higher amber percentage deepens body calm at the cost of some head lift.
Before harvest, a 7 to 10 day period of nutrient tapering or a light flush helps reduce residual mineral taste, especially in soilless systems. Keep the plant well-hydrated but not waterlogged, and reduce room humidity to 45 to 50% to begin acclimating tissues to drying conditions. A 36 to 48 hour dark period before chop is used by some growers to concentrate resin on bract surfaces, though results vary by environment.
Dry slowly at 18 to 20 degrees Celsius and 55 to 60% relative humidity for 7 to 10 days until small stems snap rather than bend. Then transfer to airtight glass jars at 58 to 62% humidity using boveda-style packs if needed, burping daily for the first week and gradually reducing frequency over the next 2 to 3 weeks. A patient cure of 3 to 6 weeks often increases aromatic intensity and smoothness and stabilizes moisture for long-term storage.
For storage, keep jars cool and dark, ideally 15 to 18 degrees Celsius, to minimize terpene oxidation. Vacuum sealing in glass or metal-lined containers can extend freshness when paired with cold storage, though repeated temperature cycling should be avoided. Properly cured and stored flowers can maintain peak aroma for 2 to 3 months, slowly mellowing thereafter while remaining potent for considerably longer.
Yield Expectations and Phenotype Variability
Indoors, Amnesia Ganja Haze Auto commonly returns 350 to 500 grams per square meter under optimized LEDs with 18 to 20 hours of light. Single-plant yields in 7 to 11 liter pots often land between 60 and 120 grams when training and feeding are dialed in. Outdoors, balcony and patio grows typically deliver 40 to 120 grams per plant depending on sunlight, container size, and seasonal length.
Grow efficiency measured as grams per watt can range from 0.6 to 1.5 with high-efficacy fixtures and good environmental control. Factors like early root establishment, conservative early feeding, and consistent irrigation can move results toward the upper end of that spectrum. Conversely, stunted early growth, high VPD swings, or overdefoliation often shave 15 to 30% off potential yields in autos.
Phenotype variation in autos is real but manageable, with most plants expressing a similar citrus-incense profile and medium height. A minority may lean slightly greener and pine-forward on the nose, while others emphasize sweet orange and floral facets. Structural variance shows up as either a single dominant cola or a more even canopy in plants that responded well to early LST.
