AMG, sometimes expanded as Amnesia Mac Ganja, is a sativa-leaning cannabis cultivar bred by Royal Queen Seeds. The strain is widely described as roughly 80 percent sativa and 20 percent indica, combining the classic cerebral brightness of the Haze family with enough structural stability to satisfy modern growers. In retail and enthusiast circles, AMG has developed a reputation for clean, uplifting energy, a pepper-citrus bouquet, and a reliably high THC ceiling suited for experienced consumers. The name itself signals both its Amnesia heritage and a selective Dutch refinement associated with the Mac Ganja lineage.
In listings for Royal Queen Seeds feminized stock, AMG is presented as uncomplicated to cultivate and adaptable to a variety of environments. This ease-of-growth profile makes it suitable for first-time gardeners, while its potency and heady character continue to engage connoisseurs. The cultivar tends to sit at the intersection of practical horticulture and sophisticated effects, which helps explain its fast-growing fan base in Europe and beyond. For many, AMG serves as a go-to daytime strain that can still offer a surprising depth of flavor and nuanced psychoactivity.
Because AMG is sold by a major European breeder, its agronomic parameters are better documented than many boutique lines. Indoor gardeners can expect a manageable stretch, reasonable flower times for a Haze-forward hybrid, and yields that align with commercial expectations. Outdoor growers appreciate that it can handle non-ideal conditions better than many pure sativas, though it still rewards ample sun and steady airflow. Overall, AMG occupies a sweet spot where vigor, potency, and user-friendly cultivation converge.
History And Breeding Origins
Royal Queen Seeds developed AMG to capture the signature kick of Dutch Amnesia while smoothing out the quirks that often make Hazes fickle in the garden. The cultivar’s branding reflects an intentional nod to Amsterdam’s coffeeshop scene, where Amnesia and Haze phenotypes helped shape the modern European palate. While the breeder has not published a granular parent-by-parent pedigree, AMG is positioned as an Amnesia-dominant line refined with a Haze-centric selection, resulting in a fast, stable, and potent sativa expression. This places AMG firmly in the lineage of late-1990s and early-2000s Dutch breeding developments that prioritized resin output, terpene richness, and consistent structure.
Over the last decade, cultivators have pushed for sativa-leaning plants that finish in reasonable indoor timeframes without demanding extreme feed or surgical canopy management. AMG reflects that trend, typically finishing in 10 to 11 weeks of bloom, which is quicker than many classic Hazes that can stretch past 12 weeks. The goal was likely to preserve the racy, talkative high of Amnesia while enhancing grower confidence across soil, coco, and hydro systems. Anecdotal reports from European grow forums consistently praise AMG for transplant hardiness and root vigor, two traits that markedly reduce early-stage losses.
As the sativa renaissance continues, AMG’s adoption in hobby gardens and mid-scale commercial rooms has increased. Its familiarity to Amnesia fans eases the learning curve for consumers and budtenders alike, maintaining recognizable flavor markers while offering a polished footprint in the canopy. The cultivar’s success echoes a broader demand for strains that are unmistakably sativa in effect but modern in cultivation practicality. In that sense, AMG reads like a contemporary answer to a classic set of consumer expectations.
Genetic Lineage And Inheritance
AMG’s core identity is Amnesia-forward, which itself is a Haze-dominant hybrid known for terpinolene-rich bouquets and cerebral lift. Although Royal Queen Seeds has kept specific parent selections undisclosed, horticultural and sensory data point strongly to a Haze-centric background with a refined Amnesia cut as the anchor. In industry shorthand, this is effectively Amnesia x Haze selection, with the Mac Ganja naming convention signifying a curated Dutch phenotype choice. The result is a plant that inherits slender leaf morphology, elongated internodes, and a strong calyx-to-leaf ratio typical of high-grade Haze family lines.
From a chemotypic perspective, AMG commonly exhibits terpene distributions aligned with the Haze family, including notable contributions from terpinolene, limonene, and caryophyllene, with supporting notes from myrcene and pinene. These compounds collectively express as peppery citrus with herbal and pine undertones, matching sensory expectations for Amnesia variants. In practice, the expression ranges from citrus-spice heavy phenotypes to slightly sweeter, more incense-leaning cuts, depending on environment and harvest timing. This variability suggests a polyhybrid ancestry where multiple sativa inputs were harmonized for stability and a desirable chemotype.
Structurally, AMG leans sativa in canopy height and stretch behavior but stops short of the extreme vertical gains seen in some pure Hazes. The cultivar tends to double in height during the first 2 to 3 weeks of flower, with well-managed specimens achieving uniform tops in Screen of Green configurations. This moderated stretch is a direct inheritance from its Amnesia-forward selection, allowing efficient light distribution over a square meter. In this way, AMG preserves sativa aesthetics while wearing the manners of a disciplined indoor hybrid.
Appearance And Bud Structure
AMG typically forms long, tapering colas with a columnar structure and a high calyx-to-leaf ratio. The bracts are medium-sized but stack densely along the stem, creating spears that can run 20 to 40 centimeters on a well-trained plant. Sugar leaves are slender and sparse, making post-harvest trimming faster than many broad-leaf hybrids. The sativa influence shows in the plant’s fan leaves, which have narrow blades and a lighter green hue during peak vigor.
Trichome coverage is generous, with a noticeable frost that intensifies from mid-flower onward. Under magnification, resin heads appear mostly cloudy near maturity, with a transition to amber in later harvest windows. Pistils generally emerge pale cream and blush orange as they mature, darkening toward rust when the flowers reach full ripeness. The overall aesthetic aligns with high-grade Haze family buds, but with a tighter, more commercial trim profile.
Some phenotypes display mild foxtailing in late flower, especially under high-intensity lighting or elevated canopy temperatures. This is not typically a sign of genetic instability but rather a response to environmental stimulus and the sativa’s appetite for light. If managed, the foxtailing remains cosmetic and does not meaningfully impact resin density or aromatic intensity. When grown in stable conditions, AMG presents as sleek, sparkling, and unmistakably sativa leaning.
Aroma And Terpene Bouquet
Fresh AMG flowers broadcast a punchy blend of crushed black pepper, lemon zest, and green herbal notes. As the buds dry and cure, sweet citrus oils intensify while an earthy, incense-like undertone emerges, lending the nose depth and persistence. Many growers report a bright top note on day 10 to day 14 of cure, followed by a rounded spice after week three. The aroma persists in storage when properly sealed with stable humidity, indicating a robust terpene load.
Dominant aromatic markers commonly trace to terpinolene, limonene, and beta-caryophyllene, with complementary contributions from myrcene and alpha-pinene. Terpinolene lends a piney-citrus brightness, limonene pushes the lemon-lime snap, and caryophyllene imparts its signature pepper and warm spice. Myrcene softens the bouquet with a light herbal base, while pinene brings a conifer edge that reads as crisp and clean. The combined effect is a nose that feels active and alerting, even before consumption.
After grinding, the bouquet blooms dramatically, often adding faint notes of anise or fennel and a whiff of floral complexity. This expansion suggests a significant monoterpene fraction, which is typical for lively sativa profiles. In vaporization, these volatile aromas translate exceptionally well at low-to-mid temperatures, rewarding careful temperature control. AMG’s aromatic signature makes it easy to identify beside milder citrus varieties and heavier, diesel-forward lines.
Flavor Profile And Consumption Experience
AMG’s flavor is consistent with its scent but tilts slightly more pepper-forward on the inhale. Expect an initial burst of black pepper and lemon peel, quickly layered with herbal sweetness and a hint of pine. On the exhale, the palate often picks up orange oil and mild anise, framed by a light earthy finish that prevents the profile from feeling thin. The mouthfeel is clean and dry rather than syrupy, which suits extended daytime sessions.
In joints and blunts, AMG burns evenly when properly cured, producing light gray ash and a smooth draw. Glass and convection vaporizers capture more of the citrus lift and reduce pepper bite, especially between 170 and 190 degrees Celsius. Dab-like vaporization of rosin from AMG can sharpen the spice and amplify limonene brightness, though at the cost of some nuance. For users who enjoy tasting sessions, stepping vaporizer temperatures upward in 5 to 10 degree increments reveals each terpene layer in sequence.
Pairing AMG with beverages accentuates different facets of the flavor. Sparkling water with lemon highlights limonene and pinene, while lightly roasted coffee draws out the caryophyllene spice. Non-alcoholic ginger tonics can echo the pepper warmth and make the citrus feel rounder and juicier. These pairings underscore the strain’s culinary versatility without overpowering its delicate top notes.
Cannabinoid Profile And Potency Data
AMG is designed for potency and typically tests in the high-THC, low-CBD bracket. In breeder descriptions and third-party lab summaries, total THC commonly falls between 20 and 22 percent by dry weight, with some phenotypes ranging from 18 to 23 percent under optimal conditions. CBD is generally low, most often below 1 percent, reinforcing the strain’s stimulating identity. Total cannabinoids can approach the mid-20s percentage-wise when minor cannabinoids are accounted for.
CBG frequently appears in the 0.3 to 1.0 percent range in Haze-forward cultivars, and AMG follows suit with low but notable CBG levels. Trace THCV is sometimes detected, occasionally in the 0.1 to 0.2 percent window, although this varies and should not be assumed. Such minor cannabinoids can subtly adjust the subjective feel, especially in synergy with the terpene mix. The overall chemical profile is firmly anchored by delta-9-THC, making AMG best suited to consumers with some tolerance or a thoughtful approach to dosing.
From a pharmacokinetic standpoint, inhaled AMG typically reaches onset within 2 to 5 minutes, with a peak around 30 to 60 minutes and a taper after 2 to 3 hours. Oral formats shift those curves considerably, with onset stretching to 45 to 120 minutes and duration extending well beyond 4 hours. This difference has practical implications for daytime use versus evening relaxation. Users should calibrate intake to context, particularly because AMG’s profile leans toward alertness and mental activation.
Terpene Profile, Ratios, And Entourage Dynamics
Although terpene outputs vary by environment and phenotype, AMG consistently expresses a citrus-spice axis dominated by terpinolene, limonene, and beta-caryophyllene. In well-grown samples, terpinolene can approach roughly 0.3 to 1.2 percent of dry weight, limonene often falls between 0.2 and 0.8 percent, and caryophyllene in the 0.1 to 0.5 percent range. Supportive terpenes such as myrcene and pinene commonly land between 0.1 and 0.4 percent each, with ocimene and linalool in the trace to 0.2 percent band. These ranges are typical for Haze-leaning hybrids that have been selected for bright aromatics and alerting effects.
The synergy between limonene and pinene is frequently cited for subjective cognitive clarity and mood elevation. Beta-caryophyllene’s ability to engage CB2 receptors may lend anti-inflammatory potential while rounding the sensory experience with pleasant warmth. Terpinolene is widely associated with uplifting sativa character and a perception of freshness, which AMG’s bouquet strongly reflects. Together, these compounds contribute to a fast, sparkly onset that many users describe as creative and sociable rather than heavy or introspective.
Cultivators can influence terpene expression by managing canopy temperature, light intensity, and harvest timing. Cooler late-flower nights around 18 to 20 degrees Celsius with stable day temperatures in the 24 to 27 degree range can help preserve monoterpenes. Early harvests at 5 to 10 percent amber trichomes often favor sharper citrus and pine top notes, while waiting for 10 to 20 percent amber deepens spice and herbal complexity. Post-harvest care, especially slow drying and a controlled cure, is critical to retaining AMG’s volatile monoterpenes.
Experiential Effects And Use Scenarios
AMG leans decidedly cerebral, offering a bright, kinetic headspace that arrives swiftly and lingers in a sustained arc. Users commonly report uplift in mood, increased conversational ease, and a sense of mental momentum that pairs well with creative problem-solving. The body feel is present but secondary, described more as upright and light than heavy or narcotic. For many, the strain aligns with daytime use, collaborative projects, and outdoorsy social settings.
Because AMG carries high THC with low CBD, it can feel intense for those prone to THC sensitivity. Some users may experience transient racy feelings or a pressure behind the eyes at peak, especially with large inhalations. These sensations usually normalize as the session settles into a clear, focused cruise. Experienced consumers often find AMG a reliable go-to for sustained energy without the jittery edge sometimes associated with pure Hazes.
Task pairing is straightforward. AMG excels in brainstorming, music production, photography walks, and light athletic activities such as disc golf or easy hikes. It can also be a strong choice for social gatherings where conversation flows and attention shifts quickly. For wind-down routines, some users blend AMG with a CBD-dominant flower to soften the edges while keeping the clarity intact.
Potential Medical Applications And Considerations
While formal clinical studies on AMG specifically are limited, its chemical profile suggests several potential use cases. High-THC, limonene-forward strains are frequently reported by patients to help with low mood, anergia, and motivational deficits. Pinene may support subjective alertness and short-term focus, and beta-caryophyllene’s CB2 engagement is often discussed in the context of inflammation and discomfort. Some individuals use similar sativa-leaning profiles for migraines or tension-related headaches, though responses vary significantly.
Because AMG is stimulating, it may not be ideal for late-night use for those prone to insomnia. Individuals with a history of anxiety or sensitivity to THC may want to start with smaller doses or consider balanced formulations. As with any cannabis product, effects are highly individualized and can be influenced by set and setting. Medical users should consult a qualified clinician, especially if taking other medications or managing complex conditions.
If AMG is used during the day for mood or energy, patients often report success with low, repeated inhalation doses rather than a single large intake. Vaporization allows precise titration and minimizes smoke-related airway irritation. Some users blend AMG with CBD-rich flower at a 3 to 1 or 2 to 1 ratio to modulate intensity without losing alertness. This approach can preserve the functional clarity many people seek while smoothing the ride.
Comprehensive Cultivation Guide: Environment, Training, Flowering, And Yields
AMG is noted by Royal Queen Seeds distributors and third-party listings as easy to grow and adaptable, despite its 80 percent sativa heritage. Gardeners consistently find that the cultivar tolerates a wide range of substrates including soil, coco, and recirculating hydro. Early vegetative vigor is strong, and plants bounce back quickly from topping and low-stress training. For beginners, this forgiving nature significantly reduces the chance of catastrophic mistakes.
Environmentally, AMG thrives in day temperatures of 24 to 28 degrees Celsius during vegetative growth, with nights around 18 to 22 degrees. Relative humidity targets of 60 to 70 percent in veg and 45 to 55 percent in early flower help maintain fast growth without inviting mildew. Late flower benefits from a gentle drop to 40 to 45 percent RH to guard against botrytis in dense colas. Aim for a VPD of roughly 0.8 to 1.1 kilopascals in veg and 1.1 to 1.5 kilopascals in bloom for steady transpiration.
Under modern LEDs, AMG responds well to a photosynthetic photon flux density of 600 to 900 micromoles per square meter per second in late veg and 900 to 1200 micromoles in mid-to-late flower. Maintain CO2 around ambient for small grows or up to 900 to 1200 parts per million in sealed rooms to leverage higher PPFD. Keep leaf-surface temperatures in check with adequate airflow to prevent terpenoid volatilization. If foxtailing appears, consider lowering intensity 10 to 15 percent or increasing canopy distance by 5 to 10 centimeters.
Nutritionally, AMG follows classic sativa demands. In coco and hydro, a feed EC around 1.2 to 1.6 in veg and 1.6 to 2.0 in bloom is a reliable starting point. Soil growers can reduce bottled nutrient strength and rely on amended media with top-dressing during week three to five of flower. Maintain pH at 5.8 to 6.2 in coco and hydro and 6.2 to 6.8 in soil for optimal macro and micronutrient uptake.
Calcium and magnesium supplementation is advisable under LED fixtures, which drive vigorous transpiration and can reveal latent deficiencies. Silica additions in veg and early bloom can strengthen cell walls, helping the tall, spear-building canopy resist mechanical stress. Avoid overfeeding nitrogen past week three of bloom to prevent leafy buds and terpene bleaching. A modest PK boost from week three to six typically supports AMG’s long cola development without sacrificing flavor.
Structurally, AMG stretches approximately 1.5 to 2 times its pre-flower height during the first 14 to 21 days of 12 and 12 lighting. Topping once or twice in late veg, followed by low-stress training, keeps vertical growth manageable and encourages multiple even tops. Screen of Green methods with 2 to 4 plants per square meter facilitate excellent light capture and airflow through the sativa canopy. Sea of Green can also work with smaller plants packed at density, but consistent cloning schedules are needed to maintain a uniform canopy.
Pruning should focus on removing interior foliage that shades bud sites and traps humidity. A light defoliation at day 21 and day 42 of flower, tailored to plant response, promotes airflow without stalling photosynthesis. Lollipop lower branches that do not reach the primary light field, redirecting energy to the top third of the plant. Use oscillating fans to achieve 0.5 to 1.0 meters per second of air movement through the mid-canopy, reducing disease risk.
AMG’s flowering time is typically 10 to 11 weeks, with many indoor growers harvesting around days 70 to 77. Outdoor in the Northern Hemisphere, expect a late September to October finish in ideal climates, with some latitudes pushing late October. Trichome evaluation is the most reliable indicator of harvest timing. For sparkling, energetic effects, harvest around mostly cloudy with 5 to 10 percent amber; for deeper spice and slightly heavier body, wait for 10 to 20 percent amber.
Yield potential aligns with commercial expectations when canopy management and environment are dialed in. Indoors, AMG commonly delivers around 400 to 500 grams per square meter under high-efficiency LED and CO2-enriched conditions. Outdoors, single plants in large containers or in-ground beds can reach 550 to 700 grams per plant in sunny climates with long seasons. These figures assume attentive IPM, steady nutrition, and reliable post-harvest handling.
Integrated pest management is essential for any long-flowering sativa. Start with prevention: clean rooms between runs, deploy yellow and blue sticky cards, and inspect new plant material thoroughly. Beneficial insects such as predatory mites and lacewings can be introduced prophylactically during veg. Avoid foliar sprays after the third week of flower to preserve resin and prevent microclimate issues in dense tops.
AMG adapts well to diverse grow setups, which echoes third-party summaries noting it is uncomplicated and adaptable to any environment. In micro-grows, the plant’s cooperative structure tolerates close-quarters training and creative trellising. In greenhouses, AMG benefits from the sativa trait of thin leaves that shed humidity quickly, so long as air exchange is robust. Across contexts, the cultivar rewards consistency more than perfection, paying growers back with aromatic, sparkling colas.
Post-Harvest Handling, Curing, And Storage
AMG’s terpene profile is rich in volatile monoterpenes, which calls for a gentle dry and patient cure. Target 18 to 20 degrees Celsius and 50 to 58 percent relative humidity for 10 to 14 days, adjusting airflow to move air without directly blasting the flowers. Large colas can be split or partially bucked to prevent moisture pockets and internal botrytis. Bending stems should progress to clean snapping as a tactile indicator that the dry is complete.
For curing, place trimmed buds in airtight containers filled to roughly 70 to 80 percent of volume to limit oxygen exposure while leaving room for burping. In the first week, open containers one to two times per day for 10 to 15 minutes, then scale back to a few times per week in weeks two to four. Maintain jar humidity around 58 to 62 percent with dedicated two-way humidity packs if needed. A 21 to 35 day cure significantly improves flavor cohesion and mouthfeel, especially for AMG’s pepper-citrus balance.
Properly cured AMG stores best in cool, dark places. Light, heat, and oxygen degrade cannabinoids and terpenes, with THC-to-CBN conversion accelerating in warm, bright conditions. Vacuum sealing and cold storage at 2 to 8 degrees Celsius can dramatically slow degradation for long-term holds, though repeated temperature cycling should be avoided. For everyday access, smaller jars help limit headspace and repeated oxygen exposure.
Extraction and rosin pressing from AMG benefit from careful temperature control to preserve the top-end aromatics. For flower rosin, 85 to 95 degrees Celsius and moderate pressure can yield flavorful presses with minimal terpene loss. Allow rosin to rest for 24 to 48 hours at cool room temperature to let volatile fractions harmonize. This attention to post-harvest detail ensures AMG’s signature nose and flavor shine through from first jar-open to final gram.
Comparisons, Pairings, And Buyer’s Guide
AMG naturally invites comparison with classic Amnesia and broader Haze family staples. Relative to many pure Hazes, AMG is faster to finish, structurally neater, and less demanding in the canopy, while still delivering a bright, energetic high. Compared with zesty lemon-forward sativas like Super Lemon Haze, AMG leans spicier and more pepper-rich, with a slightly drier mouthfeel. Against diesel or gas-leaning sativas, AMG reads cleaner and more herbal, favoring clarity over weight.
Consumers who prefer daytime clarity often keep AMG alongside a CBD-dominant cultivar for blending. A 3 to 1 AMG to CBD ratio preserves sparkle while moderating intensity for new users or anxiety-prone individuals. Flavor pairings are straightforward: citrus seltzers and light roasted coffees enhance AMG’s pepper-citrus axis without muddying the palate. Culinary pairings can include grilled vegetables with cracked pepper and lemon or herb-forward salads that echo AMG’s green top notes.
For buyers evaluating batches, look for long, spear-like colas with dense calyx stacks and a frosted surface. Break a small nug to assess aroma expansion; a lively bloom of lemon, pepper, and pine signals freshness and terpene integrity. Avoid overly grassy or hay-like notes, which can indicate rushed drying or insufficient cure. When in doubt, select producers who publish third-party lab data and provide harvest and cure dates.
