Amnesia Haze Autoflowering is a day-neutral, sativa-leaning cultivar designed to capture the zesty uplift and cerebral clarity of classic Amnesia Haze in a compact, fast-paced package. Bred by DutchFem in the Netherlands, it marries a stabilized Amnesia Haze cut with Cannabis ruderalis to remove photoperiod dependency while preserving the strain’s signature lemon-incense profile. The result is a modern autoflower that finishes reliably in roughly 10–12 weeks from sprout, even under constant 18/6 lighting.
Across European and North American grow logs, Amnesia Haze Autoflowering is widely considered a daytime favorite for its bright euphoria and motivating effects. Several reviewers and rankings have included it among standout autoflower varieties, with consistent praise for its clear-headed, functional high. Reports repeatedly highlight the strain’s ability to deliver a morning “lift,” an assessment aligned with its classic Haze heritage.
As an autoflower, this cultivar is particularly attractive to space-limited and first-time growers who want sativa effects without the long flowering phases common to photoperiod Hazes. Its manageable height, quick lifecycle, and terpene-rich bouquet make it a staple in many home gardens. The following sections break down its history, genetics, appearance, aroma, flavor, chemistry, effects, medical potential, and cultivation strategies in detail.
Origins and Breeding History
Amnesia Haze has deep roots in the Netherlands’ coffee shop era, where Haze-forward genetics gained international acclaim for their stimulating, creative highs. The original Amnesia Haze phenotype rose to prominence in the early 2000s, earning multiple competition wins and cementing its reputation as a connoisseur sativa. Its profile—lemon zest, incense, and tropical spice—became a hallmark of quality in Dutch dispensaries.
As demand for faster cycles grew, Dutch breeders began exploring ruderalis introgression to capture Haze character in a compact, day-neutral plant. DutchFem spearheaded one of the successful conversions, crossing a stabilized Amnesia Haze mother with robust ruderalis stock and backcrossing until the auto trait bred true. The goal was to maintain the uplifting, high-clarity experience while shaving months off the grow time compared to photoperiod Haze lines.
By the mid-2010s, Amnesia Haze Autoflowering had secured a place in the autos segment, with many growers reporting consistent harvests in 70–85 days from seed. Its reputation broadened beyond the Netherlands into EU and North American markets. This cultivar has since appeared on shortlists of top autoflowering strains, frequently praised for daytime use and reliable vigor.
Its ascent also tracks with industry-wide improvements in autos, which saw average THC and terpene levels climb sharply from 2012 onward. Where early autos often struggled to exceed 12–14% THC, contemporary versions like Amnesia Haze Autoflowering commonly test between 17–22% THC with total terpene content in the 1.2–2.5% range. This parity with photoperiod quality has been a driving force in the strain’s popularity.
Genetic Lineage and Heritage
Amnesia Haze Autoflowering is a ruderalis/sativa hybrid, inheriting heady cerebral traits from Haze-dominant parents and the day-neutral flowering gene from ruderalis. The Haze family typically mixes Southeast Asian and Caribbean landrace ancestry—Thai, Cambodian, and Jamaican lines are often cited contributors. These roots explain the cultivar’s citrus-forward fragrance, airy bud structure, and pronounced mental stimulation.
DutchFem’s conversion incorporated a stable ruderalis donor to trigger flowering based on age rather than photoperiod. During selection, breeders prioritized sativa morphology, high calyx-to-leaf ratios, and aromatic fidelity to Amnesia Haze. Phenotypic stabilization generally takes several generations, and reports suggest a strong uniformity in height and timing for this line.
Growers may still encounter two observable phenotypes within seed runs: a zesty, lemon-dominant expression and a more pine-incense leaning variant. Both retain sativa-leaning effects, though the lemon phenotype is often perceived as slightly more energizing. In either case, the ruderalis influence keeps plants compact and short-cycling compared to photoperiod Haze relatives.
This ruderalis/sativa heritage positions the cultivar as an excellent bridge between old-school connoisseur flavor and modern convenience. It makes high-spirited Haze effects achievable in smaller tents and balconies without light-proofing. The genetic balance also tends to produce sturdier stems and better tolerance to suboptimal photoperiod conditions.
Plant Appearance and Morphology
Amnesia Haze Autoflowering typically reaches 60–110 cm indoors and 80–140 cm outdoors, depending on pot size, lighting intensity, and environmental conditions. Internodes are moderately spaced, reflecting its sativa lean, but stems thicken enough to support top-heavy colas. Expect a 1.5–2.0× stretch after week 3, particularly under high PPFD and warm day temperatures.
Leaves present as narrow-fingered and lime to mid-green, transitioning to lighter tones with strong light and balanced nutrition. Buds develop in elongated, tapering spears with foxtail-like calyx stacking, especially when PPFD exceeds 800 µmol/m²/s late in flower. Pistils start cream to apricot and ripen to tangerine-orange, threading through a dense frost of glandular trichomes.
The calyx-to-leaf ratio is favorable for trimming, with sugar leaves staying petite and resin-coated. Under optimal conditions, buds exhibit a silver-green cast due to trichome density, indicating rich cannabinoid and terpene production. Average cola weights range from 10–20 grams dried per main stem on mid-sized plants, with exceptional phenos surpassing 25 grams when trained.
Root systems are vigorous yet fine, making the strain responsive to well-aerated media and larger final pots. In 11–15L containers, plants tend to balance canopy size with rapid, consistent flowering initiation by day 21–25. Outdoors, direct sowing into final planters improves anchor strength and reduces transplant shock, preserving the auto’s narrow development window.
Aroma and Bouquet
The bouquet is a classic Haze signature: bright lemon peel, sweet citrus rind, and fresh herbs over a backbone of incense and cedar. On the plant, the scent can be surprisingly floral at first crush, with lavender-lime notes lifting off sugar leaves. As flowers cure, deeper spice and faint pepper emerge, rounding the high-tone citrus into a balanced, perfumed profile.
Dominant aromatics often include terpinolene, limonene, and beta-caryophyllene, which together convey citrus, piney-herbal brightness, and warm spice. Many growers report a distinct zest reminiscent of grated lemon and yuzu, with a clean terpene bite when rubbing bracts. Below the top notes, you may detect green tea, coriander seed, and faint eucalyptus.
Freshness matters: terpene retention is highest when drying at 18–20°C and 55–60% RH over 10–14 days. Under rushed drying, the delicate citrus esters volatilize quickly, muting the bouquet. Proper cure restores linalool and ocimene complexity, yielding a richer, sweeter nose by week 3 of jar time.
Quantitatively, total terpenes commonly measure 1.2–2.5% by dry weight in optimized indoor runs. Limonene frequently sits at 0.4–1.0%, terpinolene at 0.3–0.9%, and beta-caryophyllene at 0.2–0.6% depending on phenotype and environment. These figures align with the strain’s pronounced citrus-incense aromatic profile and reported daytime lift.
Flavor and Palate
Expect a clean lemon-lime entry with a sweet, slightly resinous mid-palate and a peppery, incense-laced finish. The first impression is often a candied citrus akin to lemon drop or yuzu marmalade, followed by hints of green apple skin. On exhale, warming spice and cedar appear, echoing the Haze family’s classic cathedral incense.
Vaporization highlights the delicate top notes best: at 175–185°C, citrus zest and herbal tea tones dominate. Raising temperature to 190–200°C brings forward pepper, wood, and a faint diesel edge, increasing throat hit but deepening flavor. Combustion maintains lemon and spice but sacrifices some floral nuance.
Proper curing significantly improves the palate, with notable gains between weeks 2 and 6. As chlorophyll degrades and moisture equalizes, acidity softens and sweetness rises by a perceptible margin. Many tasters report the flavor stabilizes into a balanced lemon-herb profile with persistent, clean aftertaste by week 4.
Residual resin can be sticky and fragrant, with a terpene sheen that lingers on glassware. Water-cured or extended-cure flowers lose some sparkle but become exceptionally smooth, suitable for low-irritation sessions. Overall, the flavor is unmistakably Haze-forward yet approachable, accessible to both seasoned consumers and newcomers.
Cannabinoid Profile and Potency
Amnesia Haze Autoflowering typically delivers THC in the 17–22% range by dry weight under competent indoor cultivation. CBD remains low, most often 0.1–0.7%, preserving the strongly psychoactive, sativa-leaning effect. Minor cannabinoids are present in trace amounts, with CBG commonly 0.3–0.9% and CBC 0.2–0.6%.
These figures position the strain at the higher end of the autoflower potency spectrum, rivaling many photoperiod sativas. Across aggregated grower reports and lab certificates shared within the community, total cannabinoids often exceed 18% and can approach 23% in dialed-in environments. Outdoor and balcony grows usually sit toward the midpoint of the range due to variable light intensity.
Potency correlates with late-flower environmental controls, especially temperature and VPD that preserve terpene and cannabinoid integrity. Maintaining 20–24°C in the final 10–14 days and avoiding overripe harvest points can keep THC closer to peak values. Amber trichome ratios around 5–15% typically balance potency and brightness without over-sedation.
With low CBD and moderate CBG/CBC, the psychoactivity is clean and pronounced rather than body-heavy. Many users perceive a rapid onset and crisp ceiling before a gentle taper, reflecting the cannabinoid and terpene synergy. This profile aligns with the cultivar’s reputation as a productive, daytime-leaning sativa auto.
Terpene Profile and Aroma Chemistry
The terpene fingerprint is terpinolene-forward with strong limonene support, a pattern common to uplifting Hazes. Beta-caryophyllene adds warm spice and engages CB2 receptors, potentially modulating inflammation and tempering THC’s edginess. Myrcene appears in lower concentrations than many indica-leaning strains, which helps preserve the clear, non-sedative headspace.
Representative ranges for well-grown samples include terpinolene at 0.3–0.9%, limonene at 0.4–1.0%, beta-caryophyllene at 0.2–0.6%, and supporting levels of ocimene, linalool, and alpha-pinene at 0.05–0.2% each. Total terpene content generally spans 1.2–2.5%, with exceptional indoor runs surpassing 2.8%. Environmental factors like light spectrum, root-zone oxygenation, and late-flower temperature strongly influence these outcomes.
Chemically, limonene and terpinolene correlate with perceived uplift, increased alertness, and brighter mood in user reports. Pinene and linalool add cognitive clarity and gentle anxiolysis, respectively, which can smooth the high’s edges. Beta-caryophyllene’s CB2 activity is researched for anti-inflammatory potential, complementing the cultivar’s energetic psychoactive profile.
From an extraction perspective, the profile lends itself to live resin and high-terpene extract formats. Flash-freezing preserves the citrus-floral volatiles that define the strain, translating well into vape carts and dabbable concentrates. Care must be taken to avoid high-temperature purging that would degrade limonene and terpinolene and flatten the nose.
Experiential Effects and Use Cases
The effect begins with a swift cerebral lift—usually within 5–10 minutes after inhalation—accompanied by a wave of mental clarity. Users frequently report elevated mood, gentle euphoria, and a curiosity-driven focus that’s suited to brainstorming and creative tasks. Body sensation remains light, with minimal couchlock even at higher doses.
Peak intensity often arrives within 30–45 minutes and maintains for 60–90 minutes before gradually tapering over 2–3 hours. Many describe the experience as linear and functional, avoiding the heavy crash sometimes associated with denser indica profiles. Physiologically, a modest increase in heart rate and dry mouth/eyes are the most common side effects.
This is a reliable daytime strain, reflected in multiple summaries that praise its suitability for early mornings or busy afternoons. It pairs well with productivity routines, outdoor errands, and social situations where clear conversation is preferred. For sensitive users, smaller doses preserve stimulation without tipping into jitteriness.
The cultivar’s terpinolene-limonene dominance can, at very high doses, be edgy for those prone to anxiety. Simple strategies like lower inhalation temperatures, hydration, and calm surroundings mitigate this risk. Overall, the experience is bright, motivating, and consistent with its Haze lineage and widespread recognition as a top-tier auto for daytime use.
Potential Medical Applications
While formal clinical trials on this specific cultivar are limited, its chemistry suggests potential utility in mood and fatigue-related scenarios. The limonene-terpinolene-forward terpene profile aligns with user-reported improvements in motivation and affect. Patients managing depressive symptoms or anhedonia may find short-term uplift and engagement benefits with careful dosing.
Low CBD means it is not optimized for seizure control or high-anxiety presentations; however, beta-caryophyllene’s CB2 activity may offer adjunct anti-inflammatory effects. Anecdotally, individuals with mild neuropathic discomfort report distraction and cognitive reframing rather than deep analgesia. For appetite and nausea, THC can promote intake and quell queasiness, though results vary by individual and dose.
For attention-related challenges, some patients cite improved task initiation and sustained focus for 60–90 minutes post-dose. Vaporization at lower temperatures (175–185°C) can produce a cleaner headspace with fewer peripheral sensations, helpful for sensitive users. Importantly, those with anxiety or panic histories should start low to assess tolerance, given the strain’s brisk psychoactivity.
As always, medical use should be supervised by a qualified clinician familiar with cannabinoid therapy. Interactions with SSRIs, SNRIs, and other psychoactive medications are possible and warrant caution. Dosing journals and consistent product sourcing improve reproducibility and outcomes over time.
Comprehensive Cultivation Guide
Lifecycle and timing: Amnesia Haze Autoflowering typically finishes in 70–85 days from sprout, with some phenotypes running to 90 days under cooler conditions. Flower initiation commonly begins by day 21–25 regardless of light schedule. Indoor yields of 400–550 g/m² are achievable under optimized LEDs, with outliers reaching 600 g/m²; outdoors, expect 60–150 g per plant depending on latitude and season.
Environment: Aim for 24–28°C daytime and 18–22°C nighttime temperatures through most of the cycle. Relative humidity targets progress from 65–70% in seedling stage, 55–60% in early veg, 45–50% in early bloom, and 40–45% in late bloom. Maintain good air exchange (at least 30–40 air changes per hour in small tents) and cross-canopy airflow to mitigate mold.
Light: Autos perform well at 18/6 or 20/4 light schedules; most growers balance vigor and energy costs at 18/6. Target PPFD around 350–500 µmol/m²/s in week 1–2, 600–800 µmol/m²/s in weeks 3–5, and 700–900 µmol/m²/s in weeks 6–10. A daily light integral (DLI) of 35–45 mol/m²/day supports high-yield outcomes without excessive stress.
Media and containers: Use a well-aerated substrate such as 70/30 coco-perlite or light-mix soil with 20–30% perlite. Final pot size of 11–15L allows the auto to maximize root zone without hitting constraints that slow growth. Transplants should be minimized; ideally, sow directly in the final container to avoid stunting during the short vegetative window.
Nutrition: This cultivar is a moderate feeder with sensitivity to elevated EC. In coco, aim for EC 1.1–1.3 (seedling), 1.4–1.7 (veg), and 1.7–2.0 (bloom), with pH 5.8–6.2. In soil, water at pH 6.2–6.8 with light amendments and avoid over-fertilization early.
N-P-K strategy: Provide higher nitrogen in weeks 1–3 (e.g., NPK ~3-1-2), shift to balanced growth feed in weeks 3–5 (~2-1-2), then emphasize phosphorus and potassium in weeks 5–10 (~1-2-3). Supplement calcium and magnesium at 0.3–0.5 EC above base in coco to prevent interveinal chlorosis under strong LED lighting. Silica at 50–100 ppm supports stem rigidity and stress tolerance.
Irrigation: Keep media evenly moist, avoiding saturation in the first two weeks to encourage root expansion. In coco, fertigate daily to 10–20% runoff once roots establish, adjusting volume to plant size and transpiration. In soil, water thoroughly then allow the top 2–3 cm to dry before the next irrigation to reduce gnat pressure.
Training: Low-stress training (LST) is recommended from day 14–21 to open the canopy and spread apical dominance across multiple sites. Avoid late topping; if topping is attempted, do so once between day 14–18 only on vigorous phenotypes. Strategic leaf tucking and selective removal of 2–4 large fan leaves in weeks 4–5 can improve light penetration without over-defoliating.
Pest and disease management: Keep VPD within 0.9–1.3 kPa in bloom to deter botrytis and powdery mildew. Sticky traps and beneficial nematodes help control fungus gnats, while predatory mites (Neoseiulus californicus) provide insurance against spider mites. Microbial preventatives like Bacillus subtilis and potassium bicarbonate foliar sprays (pre-flower only) can suppress early mildew pressure.
Outdoor and balcony grows: Choose the sunniest location available—minimum 6–8 hours of direct sunlight daily. Use breathable fabric pots (15–20L) with added perlite for winter-spring runs to avoid waterlogging. If nights dip below 12°C, consider a small greenhouse or cold frame to maintain metabolic pace and keep harvest within 85–90 days.
CO2 and advanced controls: If enriched, maintain 800–1,000 ppm CO2 during lights-on while keeping PPFD above 800 µmol/m²/s for meaningful benefit. In the final two weeks, many growers revert to ambient CO2 to prioritize volatile retention. Gentle temperature drops at lights-off (2–4°C) can enhance color expression and terpene preservation.
Week-by-week outline: Days 1–7: establish, low EC feed, 350–450 PPFD, RH 65–70%. Days 8–21: ramp PPFD to 600 µmol/m²/s, begin LST, EC 1.4–1.6, RH 55–60%. Days 22–42: transition and early bloom, PPFD 700–800, EC up to 1.8–1.9, defoliate lightly, RH 45–50%.
Week-by-week outline continued: Days 43–70(85): mid-to-late bloom, PPFD 800–900, EC 1.8–2.0, RH 40–45%, increase K and micronutrients. Watch trichomes from day 60 onward—harvest typically aligns with cloudy trichomes and 5–15% amber. Flush schedules vary; in inert media many growers apply a 7–10 day low-EC finish for flavor clarity.
Harvest, Drying, and Curing
Harvest indicators include swollen calyxes, pistils receding and turning orange-brown, and trichomes transitioning from clear to mostly cloudy with 5–15% amber. For a brighter, more energetic effect, harvest around 0–5% amber; for a touch more body, wait until 10–15% amber. Avoid pushing beyond 20–25% amber to prevent a muted, sedative haze.
Wet trimming reduces drying time but can diminish delicate citrus volatiles; many Haze growers prefer a light dry trim followed by a final manicure post-dry. Target 18–20°C and 55–60% RH with gentle air circulation for 10–14 days to retain terpenes. Stems should snap rather than bend before jarring.
For curing, fill jars to 65–75% volume and add hygrometers to monitor moisture. Burp daily for the first 7–10 days to maintain 58–62% RH, then burp weekly thereafter. Flavor and aroma typically peak between weeks 3 and 6, with continued refinement up to 12 weeks.
Finished flower should exhibit a bright lemon-incense nose, sticky trichome heads, and a clean burn. Properly cured samples test closer to their cannabinoid and terpene potential, often showing 5–15% higher perceived flavor intensity than rushed dries. Stored in cool, dark conditions, quality holds for 6–9 months with minimal degradation.
