Amnesia Haze remains one of the most recognizable names in the Haze family, prized for its euphoric lift and laser-bright daytime clarity. It is a mostly sativa cultivar, and the version discussed here is bred by Ganja Farmer Seeds, whose selection emphasizes vigorous tropical traits and upbeat effects. Across legal markets, it is commonly described as a high-THC, low-CBD strain with a zesty citrus aroma that fills a room fast. Consumers consistently report talkative, giggly social energy with a long runway of stimulation that rarely fades before the 2 to 3 hour mark.
In crowd-sourced reviews, Leafly highlights Amnesia Haze with positive effects such as giggly, euphoric, and talkative, and with negatives like dry mouth, dizziness, and occasional paranoia. Those effect reports are consistent with the broader Haze family, which is noted for uplifting terpenes and soaring headspace. Retail lab menus routinely list THC above 20 percent for Amnesia Haze, with CBD typically at or below 1 percent. This combination sets the tone for a bright mental high, minimal body sedation, and an appreciable risk of overdoing it for first-time sativa users.
The strain enjoys a reputation for flavor as much as effect, delivering lemon zest, sweet stone fruit, and pepper-spice backed by earthy incense. Growers love it for its old-school architecture and resin production, though its long flowering time demands patience. When handled carefully, the payoff is exceptional bag appeal and a terpene profile that stands out in any lineup. The following sections break down history, lineage, look, scent, chemistry, effects, medical potential, and a full cultivation blueprint with data-backed targets.
History: From Haze Heritage to Global Favorite
Amnesia Haze rose to prominence in the early 2000s, when Haze-descended sativas were synonymous with bright, cerebral effects and cosmopolitan coffee shop culture. While various breeders have offered their own versions, this review focuses on the Ganja Farmer Seeds selection, which leans heavily into the classic, energetic Haze identity. In retail and community lore, Amnesia Haze is often linked to Caribbean and Southeast Asian influences combined with European breeding refinement. Its reputation has been bolstered by consistent competition performance and enduring demand among daytime consumers.
By the mid-2010s, Amnesia Haze became a staple in European markets and a frequent top seller wherever high-THC sativas were desired. Leafly’s strain compendium lists it as a high-THC offering, consistent with lab announcements from dispensaries that show frequent results above 20 percent THC. The strain’s ability to remain relevant through multiple waves of hybridization speaks to its balanced sensory package. It is uplifting without being purely racy, and complex in aroma without alienating new users.
The name itself conveys a tongue-in-cheek promise of strength, but the better growers and retailers highlight the finesse behind the punch. Amnesia Haze’s high feels sculpted rather than blunt, likely owing to its terpene mix and the gene pool from which it was selected. The speculation around its exact pedigree has helped its mystique, but what matters more is how consistent breeders have been at reproducing its head-focused profile. Ganja Farmer Seeds continues that line with a mostly sativa expression tuned for vigor, resin, and stable chemotype.
In the modern era, Amnesia Haze has seeded multiple offshoots and crosses, proving its breeding value. Strains like Amnesia Lemon and Northern Lights crosses use it to inject citrus clarity and long-lasting headspace. This endurance marks the cultivar as more than a fleeting trend, and as a building block for competitive modern genetics.
Genetic Lineage: Mostly Sativa, With Classic Haze DNA
Amnesia Haze is widely considered a mostly sativa cultivar drawing on Haze-family building blocks with influence from tropical landraces. While specific recipes vary by breeder, the common thread includes Jamaican and South Asian lines woven through a Haze backbone. In the case of Ganja Farmer Seeds, the emphasis leans toward sativa vigor, pronounced stretch, and a high-calyx structure that stacks foxtail-like colas under strong light. The result is an expansive canopy and a terpene signature that aligns with zesty citrus and sweet herbal incense.
Haze family terpenes often center on terpinolene, ocimene, pinene, and limonene, chemistries that power the euphoric lift for which these strains are known. Leafly’s coverage of Haze terpenes associates these molecules with alertness and mood elevation rather than heavy body sedation. Amnesia Haze typically mirrors that pattern, presenting dominant terpinolene or limonene supported by caryophyllene and myrcene in many phenotypes. This distribution is associated with clear mental stimulation and talkative sociability.
As a breeding parent, Amnesia Haze contributes an energetic high and bright citrus profile that cleanly elevates hybrids. Crosses with Northern Lights varieties tend to temper the flowering time and add density while maintaining a cerebral push. Conversely, pairing Amnesia Haze with Skunk or Lemon-forward lines can amplify citrus peel notes and reduce finish time. The versatility of its chemistry explains why this cultivar continues to appear in new, competitive hybrids.
Growers should anticipate a 1.5x to 2.5x stretch after the switch to 12 hours light, depending on phenotype and environment. Internodal spacing is often longer than average, a classic sativa trait that favors training. The canopy response to topping, low-stress training, and screen-of-green methods is generally excellent. This architecture expresses the sativa lineage in both form and cultivation strategy.
Appearance and Morphology: Tall Sativa Frames, Neon Lime Flowers
Amnesia Haze plants typically express a tall, upright frame with narrow, elongated leaflets and pronounced internodes. Under strong indoor lighting, expect final indoor heights of 90 to 150 cm when trained, and significantly taller if left unrestrained. Outdoors in warm climates, plants can top 200 cm and form spears of foxtailing calyxes with striking resin coverage. The calyx-to-leaf ratio is favorable, which eases trimming and highlights glittering trichomes.
Flowers often appear lime to neon green with golden hues and bright orange pistils that twist outward as the blossom matures. The trichome production is notable, coating bracts densely and contributing to frosty bag appeal. Though not as rock-hard as some indica hybrids, mature colas are firm enough to reward careful drying and curing without collapsing. The slightly looser Haze structure also helps airflow through the canopy, reducing risk of botrytis in humid regions.
During late flower, subtle foxtailing is common and is not necessarily a sign of heat stress with this lineage. Under high PPFD near the canopy, sativa-dominant bracts tend to stack in a columnar, segmented pattern. This morphology concentrates resin on the outer layers of the cola, enhancing aroma upon touch. The overall aesthetic is classic Haze, with a modern trichome sheen that communicates potency at first glance.
Stems are generally flexible but benefit from support by week 5 to 7 of bloom, especially in high-yield setups. Bamboo stakes, trellis netting, or a SCROG screen will keep tops upright and in the correct light zone. Expect bracts to swell late in the cycle, often in the final 10 to 14 days. That late surge contributes meaningfully to final yield and terpene intensity.
Aroma: Citrus Zest, Sweet Fruit, and Incense Spice
Open a jar of well-cured Amnesia Haze and the first impression is often lemon rind and sweet orange with a bright, sherbet-like lift. Beneath the citrus, you will find ripe stone fruit, herbal tea, and a mild pepper-spice suggesting caryophyllene. Earthy incense and cedar may appear on the exhale, a nod to the Haze heritage and the influence of terpinolene and pinene. The overall nose is loud, room-filling, and immediately recognizable.
Dry-pull aroma on a freshly ground sample tends to emphasize sweet citrus and cut grass, transitioning to spicy herbs as heat meets the terpenes. Users frequently describe the bouquet as both refreshing and complex, avoiding monotone lemon by layering in floral and woody tones. The sweetness is well integrated rather than candy-like, making it approachable for new and experienced consumers. Many enthusiasts cite the scent as a major reason for repeat purchases.
During cultivation, late-flower plants can be strongly aromatic, often requiring carbon filtration with ample airflow. The terpene peak frequently occurs in the final 2 weeks of bloom, so gentle handling and moderate environmental shifts protect the bouquet. Overly warm conditions can volatilize lighter mono-terpenes prematurely, flattening the nose. Dialing in temperature and humidity preserves the high-note citrus while letting deeper spice emerge in cure.
Flavor: Lemon Sorbet Meets Herbal Spice
On the palate, Amnesia Haze commonly delivers lemon sorbet, sweet orange peel, and a hint of mango over a spicy-herbal backbone. The first two inhales often taste brighter, with subsequent draws revealing pepper, green tea, and light cedar. This dynamic progression makes the strain engaging over a session rather than front-loaded. The finish is clean and slightly dry, encouraging another pull.
In vaporization at lower temperatures, citrus and floral tones dominate, suggesting a significant limonene and terpinolene presence. At higher temperatures, the spice and wood expand as caryophyllene and pinene volatilize. Combustion tends to emphasize sweetness at first, then deepen into aromatic spice after a few puffs. In all formats, the flavor aligns directly with the uplifting effect profile.
Proper post-harvest technique amplifies the flavor. A slow dry at about 60 degrees Fahrenheit and 60 percent relative humidity for 10 to 14 days helps retain volatile citrus compounds. Curing in airtight containers at 62 percent humidity for 3 to 6 weeks rounds the edges and integrates the spice. Over-drying below 55 percent humidity risks muting the high notes and harshing the mouthfeel.
Cannabinoid Profile and Potency: High THC, Low CBD, Long-Lasting
Amnesia Haze is best known as a high-THC, low-CBD cultivar. Retail lab results reported by dispensaries frequently place THC between 18 and 24 percent, with standout batches reaching 26 percent or higher. Seed banks commonly label it as very high THC over 20 percent and low CBD in the 0 to 1 percent range, matching the consumer experience of a strong, head-forward intoxication. This cannabinoid balance supports sustained clarity and euphoria without heavy physical sedation.
Minor cannabinoids typically appear in trace to moderate ranges. CBG may land around 0.3 to 1.0 percent, while CBC and THCV are generally detected at trace levels. These ranges vary by phenotype, growing method, and finishing window. The presence of caryophyllene and pinene in the terpene mix may interface with these cannabinoids to shape a more alert tone than typical indica-leaning hybrids.
Onset and duration reflect high-THC sativas. Inhalation onset is usually 2 to 5 minutes, peaking at 20 to 30 minutes, with total effect time commonly 120 to 180 minutes for moderate doses. Edibles or tinctures derived from Amnesia Haze can extend the experience to 4 to 6 hours, with 45 to 120 minutes to onset depending on formulation and stomach contents. Because of the low CBD baseline, the experience is less buffered and can feel intense for newcomers.
This potency profile also drives dose sensitivity. For first-time users, starting with 2.5 to 5 mg THC in edible products or a single, small inhalation is prudent. Experienced consumers may enjoy 10 to 20 mg in edibles or multiple inhalations across a session. Regardless of preferred route, hydration and pacing help mitigate common sativa side effects like dry mouth and head rush.
Terpene Profile and Chemistry: The Haze Family Signature
Leafly’s exploration of Haze terpenes associates strains like Amnesia Haze with uplifting, euphoric chemotypes. Terpinolene is often a key player in the Haze family, and many Amnesia Haze samples show it as dominant or in a tight cluster with limonene and myrcene. Supporting terpenes frequently include beta-caryophyllene, ocimene, and alpha-pinene. Together, these molecules craft the lemon-forward, herbal-spice bouquet and lively headspace.
Typical total terpene concentrations for well-grown Haze cultivars range from 1.5 to 3.5 percent by weight. Within that, terpinolene often appears around 0.3 to 0.8 percent, limonene around 0.2 to 0.5 percent, and myrcene about 0.2 to 0.6 percent. Beta-caryophyllene, ocimene, and alpha-pinene commonly populate the 0.1 to 0.4 percent band. These are general ranges and will vary with phenotype, environment, and post-harvest handling.
Functionally, limonene is associated with mood elevation and citrus brightness in aroma, while beta-caryophyllene can bind to CB2 receptors and is studied for anti-inflammatory potential. Alpha-pinene is linked to alertness and may counteract short-term memory impairment associated with high-THC exposure. Terpinolene, although sedative in some contexts, often synergizes with limonene and pinene to create a clear, effervescent profile in Haze strains. Ocimene adds sweet, green floral tones and can contribute to a crisp finish.
The terpene balance also shapes cultivation decisions. High-limonene and terpinolene expressions can be volatile under excess heat, making temperature control in late flower important. A gentle dry and long cure stabilize the bouquet and sustain top-note intensity. Growers who hit environmental targets reliably see a dramatic payoff in terpene richness and shelf appeal.
Experiential Effects: Euphoria, Conversation, and Creative Momentum
Consumers repeatedly describe Amnesia Haze as a spark plug for daytime activities. Leafly lists giggly, euphoric, and talkative among its top positive effects, which aligns with user experiences of social ease and quick wit. Energy levels climb fast, and the headspace tends to be clear rather than chaotic when dosing remains moderate. The effect often encourages task engagement, brainstorming, and outdoor pursuits.
At higher doses, a racy edge can appear, and sensitive users may report transient paranoia or dizziness. These responses track with high-THC, low-CBD chemotypes and are mitigated by smaller doses and steady hydration. Dry mouth is common and mild, often remedied by water or tea throughout a session. Placing a time limit on consumption prevents overaccumulation of THC during extended social use.
The sensory profile matches the emotion. Bright citrus and sweet fruit prime the brain for positive expectation, while pepper-spice and incense ground the experience. The high can be introspective in the first few minutes and then open outward into confidence and chatty sociability. The comedown is typically gradual and calm without heavy sedation.
For productivity, many users report good outcomes with creative tasks, light exercise, or reading. The strain pairs well with music, cooking, and recreational conversation. Those seeking deep body relief or sleep may prefer a later, heavier hybrid, as Amnesia Haze favors head-centered engagement. Its signature is forward motion rather than couch lock.
Potential Medical Uses: Uplift, Fatigue Relief, and Daytime Function
While individual results vary, Amnesia Haze’s mood-brightening profile makes it a candidate for daytime relief in cases where an energizing tone is desirable. Users self-report benefits for low mood, lethargy, and social anxiety in informal settings, especially at low to moderate doses. The uplifting terpene mix of limonene, pinene, and terpinolene is frequently discussed in relation to alertness and positivity. Because CBD content is low, the strain’s intensity warrants careful titration.
Some consumers find Amnesia Haze helpful for task initiation, which may intersect with attention and motivation challenges. The talkative and giggly effects reported on Leafly suggest a pattern of social facilitation that can ease timid interactions. Beta-caryophyllene’s CB2 activity may contribute to perceived reductions in inflammatory discomfort, although the strain is not typically marketed for heavy pain. As always, medical claims should be considered preliminary without personalized clinical guidance.
Nausea relief and appetite stimulation are sometimes noted, consistent with THC’s known effects. For migraineurs and those with anxiety proneness, the stimulating edge can be a drawback, making lower doses and calm environments important. Dry mouth and occasional dizziness are the most common downsides and are usually mild and manageable. Anyone with cardiovascular concerns should consult a clinician before using stimulating cannabis chemotypes.
If using for daytime relief, start with very small doses and target a window when you can gauge response without obligations. For inhalation, a single short puff and a 15 minute wait can be a safe trial. For edibles, 2.5 mg THC is a conservative starting point, with 2 to 3 hours allowed before redosing. Layering hydration and a light snack can buffer intensity and promote a smooth session.
Comprehensive Cultivation Guide: From Seed to Jar
Difficulty and growth habit. Amnesia Haze is a medium-to-advanced cultivar because of its long bloom time, vigorous stretch, and sensitivity to overfeeding. The Ganja Farmer Seeds selection is mostly sativa, with an indoor stretch of roughly 1.5x to 2.5x after flip. Plan training accordingly and expect a total cycle of 14 to 18 weeks from seed to harvest depending on veg length.
Environment and climate. Ideal canopy temperatures are 75 to 82 F in veg and 72 to 78 F in flower with lights on, and 65 to 70 F at night. Target relative humidity of 65 to 70 percent for seedlings, 55 to 60 percent in veg, 45 to 50 percent in early bloom, and 38 to 45 percent late bloom. These settings keep vapor pressure deficit in the sweet spot and reduce powdery mildew risk. Strong, oscillating airflow and clean intake filtration are key for a long-blooming sativa.
Lighting and intensity. In veg, a PPFD of 400 to 600 across 18 hours yields a daily light integral around 26 to 39 mol per square meter per day. In flower, aim for 800 to 1,000 PPFD for 12 hours to deliver a DLI of 34 to 43, which is ample for dense, terpene-rich colas. If supplementing CO2 to 1,100 to 1,300 ppm, PPFD can be raised to 1,100 to 1,200 with careful heat management. Keep the top of the canopy 30 to 45 cm from modern LED fixtures unless fixture-specific guidance suggests otherwise.
Media and pH. In buffered coco, run pH 5.8 to 6.2 and feed to runoff to stabilize EC. In living soil, maintain pH near 6.4 to 6.6 and water slowly to avoid channeling. Deep, aerated containers such as 3 to 5 gallon fabric pots indoors or 20 to 50 gallons outdoors support the expansive root systems sativas prefer. Good drainage prevents salt buildup and root stress late in flower.
Nutrition and EC. In coco or hydroponics, target EC 1.2 to 1.4 in late veg, 1.5 to 1.7 in early flower, and 1.8 to 2.0 in mid bloom if plants are thriving. Reduce to 1.2 to 1.4 in the final 10 to 14 days as you taper nitrogen and allow natural fade. Amnesia Haze can be sensitive to excess nitrogen after week 3 of flower, which can slow calyx swelling. A steady supply of calcium and magnesium is essential under high-intensity LEDs.
Training and canopy control. Top once or twice by the fifth to sixth node and begin low-stress training to spread growth tips horizontally. A single-layer SCROG with 5 to 7 cm mesh squares helps maintain an even canopy and keep tops in the optimal light band. For vigorous phenotypes, consider supercropping in early stretch to reduce height without stalling growth. Light defoliation before flip and in week 3 helps airflow, but avoid heavy leaf removal that can shock sativa-leaning plants.
Flowering time and scheduling. Expect 10 to 12 weeks of bloom for photoperiod plants, with some phenotypes finishing closer to week 13 under cooler late flower conditions. Pistils often continue to throw late, so verify ripeness with trichome color rather than pistil color alone. In hydroponic systems with elevated CO2, maturity can advance by several days, but terpene intensity benefits from patience. Outdoors in the Northern Hemisphere, harvest frequently occurs late October to early November.
Yields and benchmarks. Skilled indoor growers under 600 to 1,000 watts of modern LED commonly report 450 to 650 grams per square meter. Outdoor yields can range from 600 grams to 1.5 kilograms per plant in large containers with full sun and long, warm autumns. Auto-flowering versions tend to yield less but can still be impressive when managed well. In user feedback, tall autos of Amnesia Haze needed tie-downs to avoid light burn and suffered when overfed, reinforcing the variety’s sensitivity to high EC.
Irrigation strategy. In coco, light but frequent fertigations keep oxygen and nutrient levels stable, especially during rapid stretch. In soil, allow the top inch to dry between waterings while maintaining consistent moisture deeper in the pot. Avoid large volume swings that can cause micro-cracks in roots and inconsistent uptake. Measure runoff EC weekly and adjust feeds to keep drift within 0.2 to 0.3 EC from input.
Pest and disease management. Long-bloom sativas need proactive integrated pest management to avoid infestations that build slowly and explode late. Use sticky traps, weekly scouting, and beneficial insects suited to your environment. In veg, neem or insecticidal soaps can be used if compatible with your program; switch to biologicals and predatory mites in early flower. Good airflow and leaf thinning prevent microclimates that favor powdery mildew.
Outdoors and greenhouse. Amnesia Haze thrives in Mediterranean conditions with warm days, cool nights, and low late-season humidity. In temperate regions with early autumn rain, protective covers or light dep are recommended to avoid finishing in November storms. Plant in full sun with ample root volume to capitalize on the long season. Trellis early, as sativa colas will catch wind and can kink if unsupported.
Autoflower notes. Auto Amnesia Haze lines often express surprising height relative to other autos and can require tie-downs to control vertical growth. Use a 20 hours on and 4 hours off light schedule for steady growth and set final containers before day 14 to avoid transplant shock. Keep EC moderate, as autos are often overfed by new growers. Several user reports mention mild light burn and overfeeding in autos, a reminder to raise lights and lower EC promptly when tips pale.
Harvest timing and ripeness. For an energetic, clear effect, harvest when trichomes are mostly cloudy with minimal amber, around week 10 to 11 in many phenotypes. For a slightly deeper, more grounded experience, allow 10 to 20 percent amber trichomes, typically adding 7 to 14 days. Monitor aroma and calyx swelling; a substantial late swell is common. Keep a daily log in the last two weeks to correlate changes with your environment and feeding adjustments.
Post-harvest handling is covered in detail in the next section, but it bears repeating that sativa-forward terpenes are volatile. A cool trim room, gentle handling, and patience create the difference between good and great. Avoid fans blowing directly on flowers during dry to prevent terpene stripping. Store finished jars in a dark, cool space to slow terpene oxidation and preserve vibrancy.
Harvest, Drying, and Curing: Locking in the Haze Bouquet
Pre-harvest preparation. In the final 10 to 14 days, many growers reduce nitrogen and drop night temperatures by 2 to 4 degrees Fahrenheit to encourage color and preserve terpenes. Some cultivate a 36 hour dark period prior to chop, though the benefits are debated and should be tested cautiously. The most reliable gains come from stable environment and gentle handling. Clean tools and sanitize drying spaces before harvest begins.
Chop and wet work. Cut branches to manageable lengths and remove large fan leaves to improve airflow. Whether you prefer wet or dry trim, aim to minimize trichome agitation by supporting flowers from the stem. If wet trimming, be mindful that terpinolene and limonene are strongly aromatic and can volatilize quickly. Work in a cool room and move trimmed buds to the dry space immediately.
Drying targets. A classic 60 and 60 target works well for Haze cultivars, meaning about 60 degrees Fahrenheit and 60 percent relative humidity for 10 to 14 days. Gentle airflow should move air around, not across, the hanging material to avoid case hardening. Stems should snap rather than bend before jarring, which indicates internal moisture is sufficiently reduced. If your climate is arid, use humidification or closed tents to control the drop.
Curing protocol. Jar buds when the outside feels dry but not brittle, using clean glass with reliable seals. Use 62 percent humidity packs if your ambient conditions are variable, and burp jars daily for the first week, then several times weekly for the next two to three weeks. A minimum of 21 days of cure substantially improves flavor integration and smoothness. Many connoisseurs report peak citrus brightness between week 4 and week 8 of cure for Amnesia Haze.
Storage and stability. Keep jars in a dark, cool space to slow terpene oxidation, which can dull citrus top notes. Avoid freezing fresh-cured jars, as condensation on thaw can degrade trichomes and alter mouthfeel. Properly dried and cured Amnesia Haze can maintain its vibrant nose for several months with minimal loss. Label each jar with harvest date, phenotype, and cure milestones for future reference.
