Written by Ad OpsOrigins And Breeding History
Amnesia Haze stands among the most storied sativa-dominant varieties of modern cannabis, and the Bulk Seed Bank rendition is one of the best-known commercial lines. Bulk Seed Bank stabilized a mostly sativa phenotype to highlight the classic Haze uplift with improved yield and consistency. Their selection work focused on vigorous growth, long-running colas, and a terpene bouquet true to the Haze family. In today’s market, Bulk Seed Bank’s Amnesia Haze is a reference point for growers who want Haze character without sacrificing production.
The strain’s international rise dovetailed with the broader popularity of Haze hybrids in the 2000s. Sativa-forward strains typically impose longer cultivation cycles, yet the reward for patient growers is a high that consumers consistently describe as bright, euphoric, and long-lasting. Retail platforms consistently list Amnesia Haze as a “high THC, low CBD” option, in keeping with the sativa profile. That potency reputation helped lock the cultivar into the menus of European coffee shops and North American dispensaries alike.
Culturally, Amnesia Haze earned word-of-mouth fame for its almost effervescent head buzz and conversation-friendly vibes. Leafly’s community consistently tags it with “giggly,” “euphoric,” and “talkative” as top-reported effects, which tracks with long-standing Haze lore. The strain’s energy and social appeal made it a daytime favorite, especially in creative scenes and collaborative work environments. Over the years, those consistent experiential reports encouraged breeders to keep preserving its prime traits.
The strain’s branding often emphasizes its prestige and psychedelic lean, and consumer seed shops echo that reputation. For example, product descriptions regularly note its “very high” THC potential—over 20% in many tested batches—and a classic sativa headspace. In comparison to couch-locking indicas, Amnesia Haze is said to lift mood, focus the mind, and inspire activity. Those traits, combined with an unmistakable citrus-spice profile, help differentiate it from other crowd-pleasing sativas.
Because so many breeders have released their own Amnesia Haze versions over the years, it is normal to encounter multiple “house cuts” or slightly different expressions. Bulk Seed Bank’s line leans into a balanced approach: unequivocally sativa in feel, yet relatively manageable in flower structure and cultivation. This makes it appealing to both home growers and commercial operators who want a reliable Haze that can fill a canopy. The end result is a cultivar that bridges old-school Haze character with modern grow-room practicality.
As legalization expands and lab data accumulates, the strain’s high-THC, terpinolene-forward chemical fingerprint has become better documented. Across different markets, Amnesia Haze samples commonly test in the 18–26% THC window, with CBD near or below 1%. That chemical consistency reinforces the longstanding anecdotal reports of strong cerebral effects. In effect, lab data now validates what connoisseurs have been saying for years.
Genetic Lineage And Dominant Phenotypes
Genetically, Amnesia Haze belongs to the Haze family, a group known for tropical sativa ancestry and terpinolene-rich profiles. Bulk Seed Bank’s version is described as “mostly sativa,” and the phenotype distribution supports that claim in both plant morphology and effect. Expect lankier internodes, narrower leaflets, and a prolonged flowering period relative to indica-dominant hybrids. The result in the jar is a striking calyx-to-leaf ratio and colas that can run long once trained correctly.
The specific heritage behind Amnesia Haze lines can vary by breeder, but most converge on a Haze-forward base with complementary landrace influences and strategic hybridization. In practical terms, growers will see vigorous apical dominance and rapid vertical stretch after the flip to 12/12. It is common to measure 100–150% stretch over the first 2–3 weeks of flowering in high-intensity indoor setups. That growth pattern aligns closely with classic Haze behavior.
From a chemotype perspective, Amnesia Haze often expresses a terpinolene-dominant terpene stack with supporting limonene, beta-caryophyllene, myrcene, and ocimene. That chemical profile correlates with the uplifted, sparkling mental effect reported by consumers. In testing labs, terpinolene-rich sativas are strongly associated with “Haze” sensory signatures: citrus peel, fresh herbs, and gentle pine. Amnesia Haze checks each of those boxes with surprising consistency.
Phenotypically, growers may encounter two broad expressions within Bulk Seed Bank’s line. One leans toward extreme sativa, with longer internodes and a finishing time closer to 12 weeks after flip in cooler rooms. The other matures slightly faster, finishing around 10–11 weeks, with slightly tighter nodes and denser colas. Both versions retain the electric headspace and citrus-spice aroma that define the cultivar.
Given the strain’s long flowering window, patient selection pays off. Growers seeking a slightly earlier finish should scout for plants that stack calyxes more tightly by week 6–7 of bloom. Conversely, connoisseurs willing to run the full 12 weeks can unlock especially resinous, aromatic flowers with heightened terp intensity. This is a classic case where extra time in the room translates to extra quality in the jar.
In summary, think of Bulk Seed Bank’s Amnesia Haze as a stabilized, production-minded sativa that honors the hallmark Haze experience. It offers the lanky frame and long-running colas sativa lovers crave, but with a trait balance that improves canopy management. For growers who top, train, and feed with discipline, the phenotype rewards with top-shelf nose and a soaring effect profile. For consumers, the chemotype delivers the daytime clarity that made Haze strains famous.
Appearance And Bag Appeal
Amnesia Haze produces elongated, elegant flowers that showcase its sativa dominance at a glance. Mature colas can form spears, especially in well-managed SCROG canopies where light penetrates evenly. The calyxes stack in a way that creates textured surfaces with pronounced foxtailing in heat or under very intense LEDs. When dialed in, that foxtailing is subtle and attractive, contributing to the cultivar’s signature silhouette.
Coloration ranges from lime to medium forest green, often accented by amber to tangerine pistils as harvest nears. In cooler nights late in bloom, some phenotypes flash faint lavender hues along sugar leaves, a visual bonus for photographers and dispensary displays. Trichome coverage is abundant, with bulbous heads that frost the bracts and give a shimmering, almost wet look. Under magnification, the gland density is evidence of its high-THC potential.
Bud density sits in the middle of the sativa spectrum: not airy, but not golf-ball firm like indica-dom hybrids. That medium density helps the flowers dry and cure evenly, reducing the risk of trapped moisture. Properly grown and trimmed, the buds present a high calyx-to-leaf ratio that makes hand-trimming efficient. The end product breaks down pleasantly and burns clean when dried and cured to spec.
In a jar, Amnesia Haze shows strong curb appeal thanks to its resin sheen and vibrant pistils. Consumers often comment on the “sparkly” look that hints at potency before the first inhale. Retailers appreciate that the flowers maintain structure during handling without crumbling. Overall, it’s a photogenic, shelf-ready example of modern sativa craftsmanship.
Large, well-cultivated tops can weigh surprisingly well despite the leaner Haze morphology. This is especially true in CO2-enriched rooms where calyx expansion continues late into weeks 9–12. Even smaller side branches produce attractive satellite buds that trim into tidy eighths. For bag appeal, Amnesia Haze checks all the boxes a shop buyer wants to see.
Aroma And Bouquet
The first impression on opening a jar of Amnesia Haze is often a wave of zesty citrus layered with sweet tropical notes. Juniper and fresh-cut herb nuances follow, a calling card of terpinolene-forward chemotypes. There’s a light pine thread that helps the bouquet feel bright and clean rather than sugary. Many noses also pick up a subtle spice—think white pepper or coriander—that hints at beta-caryophyllene in the background.
As the flowers are ground, the aroma expands into lemon zest, ripe mango, and sweet basil. That progression from citrus-herbal to citrus-tropical is a hallmark of Haze families with ocimene and limonene support. The overall nose skews high-key and uplifting, without the heavy musk found in skunkier cultivars. For consumers who prioritize a fresh, daytime-ready scent, Amnesia Haze is tailor-made.
Leafly’s coverage of Haze-family terpenes notes that terpinolene is strongly implicated in the euphoric, uplifting sensory experience. In Amnesia Haze, the terpinolene peak typically drives the “bright” perception that many consumers describe as focusing or clarifying. Meanwhile, limonene contributes the lemon-peel sparkle that comes forward upon breaking a nug. These pieces click together to create a bouquet that feels both lively and clean.
Storage conditions influence the nose dramatically because terpinolene and ocimene can volatilize quickly. Kept in airtight glass at 62% relative humidity and 18–21°C, the aroma remains vibrant for months. Exposure to heat or low humidity, by contrast, flattens the citrus top notes and can leave a faintly woody residual. Proper curing is crucial to preserve the full aromatic arc from jar to grinder to pipe.
In mixed jars with other strains, Amnesia Haze can dominate the olfactory mix. Its citrus and herb top notes tend to cut through, even against funkier profiles. Connoisseurs often store it separately for this reason, preserving its clarity and preventing cross-perfuming. That clarity is part of its enduring appeal to aroma-focused buyers.
Flavor And Mouthfeel
On the inhale, Amnesia Haze delivers lemon-lime brightness with a clean herbal edge. The first seconds can taste like citrus oil spritzed over fresh parsley, followed by a gentle pine lift. As the vapor expands, some phenotypes add sweet tropical suggestions of mango or papaya. This is a palate that feels refreshing rather than cloying.
The exhale leans more peppery and resinous, a nod to beta-caryophyllene and pinene interplay. A faint white-pepper tickle on the back of the tongue is common, especially at higher temperatures in vaporizers. When rolled, the joint smoke stays crisp and light if the cure is done at 55–62% RH. Harshness is minimal when chlorophyll has been properly purged over a slow, two-week dry.
Flavor intensity scales with grinding and heat. Finely ground flower in a convection vaporizer at 180–190°C preserves citrus while unlocking a fuller herbal bouquet. Raising to 200–205°C deepens the spice and wood elements, albeit at the cost of some top-note sparkle. Most flavor chasers prefer staying below 200°C to keep the citrus dominant.
Keeled bowls and well-tamped joints accentuate the even burn and clean finish of this cultivar. That balanced combustion profile is one reason Amnesia Haze remains a shop staple—it enhances the tasting experience for new consumers. With concentrates, the lemon-herb fingerprint becomes even more concentrated, sometimes bordering on lemon-candy. In rosin, the pepper finish rounds out the sweetness for a sophisticated, layered sip.
Pairings that compliment the profile include sparkling water with a twist of lemon, green grapes, and soft goat cheese. The palate synergy reinforces the zesty, herbal lane without overwhelming it. For coffee drinkers, a bright Ethiopian light roast often harmonizes with the citrus notes. The net result is a tasting experience that is as culinary as it is psychoactive.
Cannabinoid Profile And Potency
Amnesia Haze is consistently categorized as high THC and low CBD. Lab-tested lots commonly register between 18% and 26% THC by dry weight, with a market average clustering near 20–22% for dispensary-grade flower. CBD typically measures below 1%, and many batches sit near the assay detection limit. Minor cannabinoids such as CBG often appear in the 0.1–1.0% range, adding nuance without diluting the THC-forward effect.
To translate those percentages into practical dosing, 22% THC corresponds to approximately 220 mg THC per gram of flower. A typical 0.25 g pipe bowl would therefore contain roughly 55 mg of total THC before combustion losses. Inhalation bioavailability varies widely, but published ranges of 10–35% suggest a realized dose of around 5.5–19 mg from that bowl. Individual tolerance, inhalation technique, and device efficiency can push those numbers up or down.
For edibles and tinctures made from Amnesia Haze, decarboxylation is the key step that converts THCA to psychoactive THC. Home decarb protocols often target 105–115°C for 30–45 minutes, yielding 70–90% conversion efficiency depending on oven accuracy and material moisture. If extracting from one gram at 22% THC-equivalent potential, a 75% efficient process would liberate about 165 mg of active THC. Divided into ten servings, that’s a potent 16.5 mg per piece—enough to be very noticeable for most users.
Because the strain is largely sativa in heritage, it exhibits chemovars that skew toward THCV trace production. While most flower tests place THCV below 0.5%, its presence is not unusual in Haze-linked genetics. THCV’s contribution at trace levels is subtle, but some consumers report a brighter, more “edge-trimmed” headspace when THCV is detectable. This remains an area of active interest rather than a guaranteed effect.
Concentrates made from Amnesia Haze reflect the parent flower’s potency potential. Hydrocarbon extracts can easily test above 70% total cannabinoids, with live resins and sauces preserving the citrus-terpinolene top notes. Solventless rosin from high-grade, late-harvest material can push 60–75% total cannabinoids depending on starting quality and press parameters. For both production and connoisseur use, Amnesia Haze is a strong basis for energetic daytime dabs.
Overall, the cannabinoid profile is clear: high THC, very low CBD, and a supporting cast of minors that generally stay under 1% each. This skews the experiential effect toward a lucid, high-ceiling headspace that is sensitive to dosage. Newer consumers should consider microdosing inhaled THC at 1–3 mg to gauge response. Experienced users will find the strain scales up reliably without turning muddy or sedative until very high doses.
Terpene Profile And Chemical Nuance
Chemically, Amnesia Haze is a textbook terpinolene-dominant sativa with vibrant supporting terpenes. Total terpene content in well-grown, slow-cured indoor flower commonly lands between 1.5% and 3.0% by weight. Within that total, terpinolene often ranges from about 0.4% to 1.0%, setting the citrus-herb tone that defines the nose. Limonene, beta-caryophyllene, myrcene, ocimene, and alpha-pinene fill in the remaining layers.
Limonene typically shows between 0.2% and 0.5% and contributes the lemon-zest brightness perceptible as soon as a jar is opened. Beta-caryophyllene commonly appears in the 0.2% to 0.5% range and imparts a pepper-resin finish that lingers on the palate. Myrcene is lower than in “couch-lock” indicas, often around 0.2% to 0.6%, which helps keep the overall feel uplifting rather than sedative. Ocimene (0.1–0.3%) and alpha-pinene (0.1–0.3%) add sweet greenery and a crisp, pine varnish.
This terpene architecture aligns with the Haze family’s classic reputation for euphoric clarity. Leafly’s exploration of Haze terpenes highlights terpinolene as a driver of the airy, energetic mood many people associate with these cultivars. In Amnesia Haze, that manifests as a sparkling headspace and a sense of motivational lift. The synergy with limonene reinforces mood elevation and a “sunny” sensory frame.
When cured optimally, the terpene ensemble unfolds in stages as the flower is handled and heated. Cold aroma leans lemon-herb, while grinding liberates ocimene and pinene for a greener burst. As vapor temperature rises past 190°C, caryophyllene’s peppery backbone becomes more persuasive. This dynamic sequence gives the strain excellent range in vaporizers where temperature control is precise.
Terpene preservation requires attentive post-harvest. A slow dry at 18–21°C and 50–60% RH over 10–14 days helps retain the most volatile fractions, including terpinolene. Curing in airtight glass with 62% humidity packs smooths rough edges and integrates the bouquet over 3–6 weeks. Under those conditions, sensory panels consistently rate the citrus intensity higher and the finish cleaner.
From a formulation perspective, Amnesia Haze’s terp profile is friendly to daytime-focused products. Vape cartridges that highlight terpinolene and limonene capture the cultivar’s optimistic character. Likewise, live resin and live rosin SKUs based on this strain often emphasize “citrus spritz” and “herbal sparkle” descriptors. The chemistry and the branding narrative reinforce each other naturally.
Experiential Effects And Use Scenarios
Consumer reports consistently describe Amnesia Haze as giggly, euphoric, and talkative. This aligns with its sativa-dominant heritage and terpinolene-forward chemistry. Leafly lists those exact effects among the most common experiences, and users also note a clear-headed uplift suitable for daytime. The stimulation is bright without being jittery for most people at moderate doses.
Onset after inhalation is typically felt within 2–5 minutes, peaking around 15–30 minutes, and sustaining for 120–180 minutes. That arc is ideal for morning and afternoon activity—creative work, socializing, light exercise, or errands. The strain’s social lubrication pairs well with cooperative tasks and brainstorming. Many users describe an improved flow state where conversation and idea generation come easily.
Potential adverse effects mirror other high-THC sativas: dry mouth, dizziness, and occasional paranoia at high doses. Leafly users commonly report those three as the main negatives. For dose-sensitive individuals, micro-hits or 1–2 mg THC increments minimize the risk of anxiety. Hydrating before and during sessions also blunts cottonmouth and lightheadedness.
Dose planning can make or break the experience. A single small inhalation from a modern vaporizer may deliver 2–6 mg THC depending on device and product potency. For a typical joint, three short puffs could easily cross 5–10 mg realized dose in a few minutes. If prone to overthinking, build slowly to the desired effect and avoid stacking hits back-to-back.
Task pairing is straightforward. For creative pursuits—music sketching, design sprints, or writing prompts—the strain’s uplift lends momentum without heavy body load. For social contexts, it keeps conversation animated and inclusive. Outdoors, it pairs naturally with walking, light cycling, or a park hang under good weather.
Evening use is possible, but the stimulating mental lane makes it less suitable for sleep. At very high doses, the effect may shift from sparkling to foggy as cognitive saturation sets in. Users who want a gentle landing can blend a small amount of a myrcene-rich indica later in the session. That hybrid approach reintroduces body grounding without dulling the earlier brightness.
Potential Therapeutic Applications
While individual responses vary and clinical validation is ongoing, Amnesia Haze’s profile suggests potential utility for low-energy mood states and daytime analgesia. The limonene-terpinolene axis is frequently associated with mood elevation and a sense of optimism in observational reports. Users often report increased motivation and sociability, which can be supportive for mild, situational depression or fatigue. Because CBD is minimal, the experience leans stimulating rather than calming.
For attention and focus, some patients anecdotally find sativa-dominant strains helpful during tasks requiring ideation. The talkative, exploratory headspace can make brainstorming and creative work more engaging. That said, for tasks requiring linear concentration and minimal distraction, the effervescent mental tone can be too lively. Matching the strain to the activity is a prudent strategy.
Pain relief is not this cultivar’s primary claim to fame, yet high-THC content can still blunt mild to moderate discomfort. Beta-caryophyllene’s interaction with CB2 receptors may contribute peripheral anti-inflammatory support, though typically at modest levels. Users sometimes report reduced headache intensity and improved tolerance of nagging aches during the strain’s peak. For severe or neuropathic pain, heavier, myrcene-forward chemovars may be more effective.
Nausea relief is a plausible use case given the rapid onset and pleasant flavor that encourages inhalation. Sipping a low dose via vaporizer can bring quick comfort without sedating the user. Appetite stimulation is moderate; some individuals will notice a slight uptick in hunger after the peak. In contrast to deep-indica “munchie” strains, Amnesia Haze keeps appetite increases relatively controlled for many users.
For anxiety-prone individuals, caution is advised. The same high-THC, stimulating chemistry that lifts mood can tip into racing thoughts at higher doses. Starting at 1–3 mg inhaled THC and waiting 10–15 minutes to assess is a safer on-ramp. Pairing with a CBD-dominant product is another tool to balance the experience if needed.
As always, medical decisions should be made in consultation with a healthcare professional, especially for those with cardiovascular conditions or psychiatric histories. Cannabis responses are highly individualized, and daily medications can interact with cannabinoids. That said, observational data and widespread consumer feedback place Amnesia Haze among the more uplifting daytime options. Its sensory brightness and cheerful mood lift are consistent themes in user narratives.
Comprehensive Cultivation Guide
Amnesia Haze is a mostly sativa cultivar from Bulk Seed Bank that rewards attentive growers with top-tier citrus-herb flowers and a lively effect. Expect a longer flowering cycle than indica hybrids and plan your room accordingly. The plant stretches significantly after the flip, and training is essential to keep canopies even. With discipline, indoor yields can reach 450–600 g/m², and outdoor plants can exceed 600 g per plant in favorable climates.
Germination and seedling stage are straightforward. Use fresh, viable seed and germinate in a lightly fertilized medium at 22–26°C with 70–80% relative humidity. Seedlings prefer gentle light intensity—200–400 PPFD for the first week—and a VPD near 0.8–1.0 kPa. Aim for a soil pH of 6.2–6.8, or 5.8–6.0 in coco and hydroponics.
Vegetative growth benefits from bright, but not extreme, light and regular training. In weeks 2–4 of veg, move PPFD up to 400–600, with a daily light integral in the 25–35 mol/m²/day range. Topping once or twice and using low-stress training helps spread the canopy and set up a SCROG grid. Keep temps 24–27°C day, 20–22°C night, and humidity 55–65% with VPD 1.0–1.2 kPa.
Nutrient needs are moderate in veg and higher in bloom. In coco/hydro, maintain EC around 1.2–1.6 mS/cm in veg with nitrogen-forward formulations and ample calcium/magnesium. For soil, feed lightly and let the medium’s cation exchange capacity do the heavy lifting, supplementing with balanced teas or top-dresses. Water to 10–15% runoff in inert media to prevent salt buildup.
Flip to 12/12 photoperiod when the canopy is ~60–70% of final height to account for stretch. Expect 100–150% vertical expansion over the first 2–3 weeks post-flip under high-intensity LEDs. Use trellis netting early and continue low-stress training to keep tops even. Leaf defoliation should be selective, removing blockers to improve airflow without over-stripping sativa leaves.
Flowering typically runs 10–12 weeks for most phenotypes, occasionally up to 13 weeks in cooler rooms. Early bloom (weeks 1–3) favors EC 1.6–1.8 and a steady increase in phosphorus and potassium. Mid bloom (weeks 4–7) can take EC 1.8–2.1 as calyx stacking accelerates; monitor for tip burn as a sign to hold or back off. Late bloom (weeks 8–12) often benefits from a slight nutrient taper to enhance resin expression and flavor.
Environmental controls are crucial for terpene retention and disease prevention. Target 24–26°C days and 19–21°C nights in bloom. Keep humidity around 50–55% in early flower, 45–50% mid flower, and 38–45% in the final two weeks. Hold VPD near 1.2–1.4 kPa initially and 1.3–1.5 kPa for the finish to reduce botrytis risk.
Light intensity can be pushed when CO2 supplementation is in place. Without added CO2, aim for 700–900 PPFD mid bloom and up to 1,000–1,100 PPFD late bloom for high-par plants. With 1,000–1,200 ppm CO2, the canopy can utilize 1,100–1,300 PPFD, potentially boosting yield by 15–30% if irrigation and nutrition are balanced. Always ramp intensity gradually to avoid light stress.
Integrated pest management should prioritize airflow and sanitation, as the long flowering window invites opportunists. Rotate beneficial predators and use preventatives like horticultural oils during veg only. Scout weekly for spider mites, thrips, and powdery mildew, and maintain a strong air exchange with HEPA intake filtering if possible. Keep leaves dry during dark cycles to limit fungal pressure.
Harvest timing for peak flavor and an energetic effect is typically around milky trichomes with 5–10% amber. At this point, the citrus-herb top notes remain high, and the headspace is sparkling. Waiting for 15–20% amber shifts the effect toward a calmer, more grounded finish. In practice, many growers split the harvest to offer both profiles to consumers.
Drying should be slow and cool to retain terpinolene and ocimene. Hang whole plants or large branches in 18–21°C, 50–60% RH, with gentle air movement for 10–14 days. When outer stems snap and smaller buds feel slightly springy, move to curing jars. Burp daily at first and stabilize at 62% RH for 3–6 weeks to maximize smoothness and aroma integration.
Outdoor cultivation favors Mediterranean conditions with warm, sunny days and low autumn rain. In-ground plants can exceed 2 meters tall with proper soil building and staking. Plan for harvest in mid to late October in the Northern Hemisphere, watching weather carefully to avoid late-season mold. Growers in short, wet seasons may prefer a greenhouse or light-dep to finish earlier.
Autoflower variants of Amnesia Haze exist and can grow taller than expected. Grower feedback notes that some auto phenotypes stretch aggressively and may require tie-downs to keep tops off the lights. Mild light burn at canopy peaks and a tendency to overfeed are common pitfalls. Start autos at moderate feed levels and increase only as leaf color demands.
Common mistakes with Amnesia Haze include underestimating stretch, overfeeding late bloom, and rushing the dry/cure. Correcting any one of these can materially improve quality, but getting all three right produces exceptional results. Focus on even canopies, disciplined EC, and terpene-preserving post-harvest. The payoff is a jar that commands attention with both nose and effect.
Targeted metrics recap can help dialing in: veg pH 6.2–6.8 soil or 5.8–6.0 hydro; bloom EC 1.6–2.1; veg RH 55–65% and bloom RH tapering from 50–55% to 38–45%; PPFD 400–600 veg and 800–1,100 bloom; and finishing trichomes at mostly cloudy for daytime punch. Under those parameters, Bulk Seed Bank’s Amnesia Haze reliably expresses its best self. Expect distinctive terpinolene-driven aroma, lively sativa effect, and a quality of resin that translates beautifully to both flower and extract. For growers and consumers alike, it’s an enduring benchmark of the Haze tradition.
