Amnesia Amazon Haze is a modern haze hybrid bred by R-KIEM Seeds, a European breeder known for resin-forward selections and careful stabilization. The strain’s name signals two pillars of its identity: the sparkling clarity of Amnesia-type hazes and a lush, tropical haze influence evoked by the Amazon moniker. The breeder’s stated heritage category of ruderalis, indica, and sativa points to a deliberate multi-pool cross designed to balance vigor, structure, and day-neutral flowering potential. In practice, this creates a contemporary haze that aims to be more forgiving to cultivate than old-school, long-flowering tropical lines.
The Amnesia portion of the pedigree nods to a lineage that has won multiple Cannabis Cup awards and has set a benchmark for citrus-forward, uplifting sativa experiences. Amnesia-type hazes are frequently lab-tested in the mid-high THC bracket, with many commercial batches ranging from about 18% to 24% THC by dry weight, which equates to roughly 180 to 240 milligrams of THC per gram of flower. This potency profile has shaped expectations for a fast-onset, euphoric, and motivational effect. R-KIEM’s contribution lies in taming the growth curve while preserving the signature sensory sparkle.
By weaving in ruderalis genetics, the breeders sought to expand the cultivation envelope and shorten total crop time for some phenotypes. Day-neutral flowering traits can reduce reliance on strict photoperiod changes and help synchronize harvest in tighter schedules. The indica touch likely contributes to density, a stronger calyx-to-leaf ratio, and firmer bud architecture compared to wispier haze expressions. Together, the composite aims at an enthusiastic sativa experience within a grower-friendly chassis.
Since release, Amnesia Amazon Haze has found traction with home cultivators and small craft grows looking for citrus-forward terpenes and energetic effects. Reports from experienced growers often highlight a hospitable training window and responsive branching, especially under high-intensity LEDs. In markets that reward terpene-driven profiles, the cultivar’s bright bouquet of citrus, pine, and floral incense can stand out on a retail shelf. Consistency through proper selection and phenohunting remains critical to capturing its full haze character.
Overall, the breeding objective was to deliver a haze you can schedule. While maintaining the uplifting potency associated with Amnesia lines, R-KIEM Seeds worked in genetics that improve resilience and shorten finishing times relative to pure tropical sativas. The result is a cultivar that bridges classic haze appeal with modern cultivation realities. In capable hands, it can express the best of both worlds: high-energy aroma and flavor, alongside a manageable growth profile.
Genetic Lineage and Inheritance
R-KIEM Seeds lists the heritage of Amnesia Amazon Haze as ruderalis, indica, and sativa, indicating a three-pool approach. The sativa core frames the high-limonene and terpinolene leaning sensory profile, taller stature, and sun-loving vigor. The indica influence often tightens internodes, thickens calyces, and improves trichome coverage, which is crucial for the cultivar’s resin-rich presentation. The ruderalis portion introduces the possibility of day-neutral flowering, commonly called autoflowering.
In plants that express the ruderalis trait, flowering initiates by age rather than day length, typically within 3 to 5 weeks from sprout. This can lead to seed-to-harvest cycles in roughly 70 to 95 days under an 18-hour light schedule, depending on phenotype and environment. In lines where the ruderalis expression is recessive or intentionally minimized, the cultivar behaves like a photoperiod haze hybrid, requiring a 12-hour dark cycle to trigger bloom. That duality is why verifying the specific seed line and pack notes is important before scheduling a grow.
Haze ancestry often imparts elongated internodes and a 1.5 to 3.0 times stretch after the onset of flowering. The indica component tempers this, which helps indoor cultivators keep canopies even. This blend also encourages a higher calyx-to-leaf ratio compared to pure sativa expressions, making trimming easier and improving bag appeal. A balanced architecture lets the plant take well to low-stress training and screen-of-green strategies.
Chemotypically, the strain trends THC-dominant with modest minors such as CBG and trace CBD in many haze-descended hybrids. The terpene ensemble commonly features terpinolene, limonene, myrcene, and beta-caryophyllene in various proportions. These compounds contribute to citrus peel, pine-lilac, and peppery incense notes that haze enthusiasts often seek. The net effect is uplifting and clear, with a stimulating edge that rewards daytime use for many users.
Morphology and Appearance
Amnesia Amazon Haze typically grows with sativa-forward posture, presenting medium-long internodes and lanky, upward-reaching branches. Fan leaves often carry a slender, lanceolate shape with light to medium serration, and a lighter green chlorophyll tone in fast, high-light grows. During early to mid-veg, the plant can rapidly stack nodes, responding well to gentle bending to even the canopy. The overall silhouette is elegant rather than squat.
In flower, bud sets organize along sizable colas with a noticeable calyx stack that can foxtail slightly under high PPFD or late-flower heat spikes. Buds exhibit a lime-to-emerald green palette with a sheen of resin that thickens significantly by weeks 6 to 9 of bloom. Orange to copper pistils weave through the canopy and transition to deeper amber as maturity approaches. Sugar leaves are modest, which simplifies post-harvest processing.
A well-grown sample often shows a frosty trichome mantle, with bulbous heads that hold the citrus-forward oils. Under magnification, trichomes progress from clear to cloudy, with amber appearing later in the harvest window as cannabinoids oxidize. The calyx-to-leaf ratio leans favorable for a haze, a nod to the indica input in the lineage. This balance enhances visual appeal while retaining the classic haze bud shape.
Indoors, an untrained plant can readily reach 90 to 120 centimeters before flip and finish 1.5 to 2.0 times taller depending on the cut. Outdoors in full sun and warm climates, plants can exceed 200 centimeters with broad lateral branching. Canopy management with stakes or trellis is advised to support heavy top colas during late bloom. Good airflow helps prevent microclimates, which is especially important in dense, resinous tops.
Dried and cured flower presents a sparkling surface and a structured yet slightly wispy haze architecture. The buds break apart with a balance of stickiness and spring, reflecting adequate cure humidity around 58% to 62% RH. The groomed flower’s visual signature aligns with consumer expectations for modern haze hybrids. Altogether, the cultivar offers the bright, resinous look that complements its uplifting chemotype.
Aroma and Sensory Notes
Aroma begins with a clear blast of citrus rind, especially lemon and sweet lime, supported by piney and floral overtones common in terpinolene-forward hazes. Underneath the citrus, you may detect a sweet herbal facet akin to fresh basil and fennel tips, suggestive of ocimene and myrcene contributors. A faint peppery tickle and incense-like wood follow, hallmarks of beta-caryophyllene and trace humulene. The bouquet is clean, crisp, and stimulating.
When a nug is broken open, the citrus peels intensify while a resinous, coniferous heart note expands. Some phenotypes show a tropical edge reminiscent of passionfruit or guava, likely the interplay of monoterpenes layered on a haze backbone. The grind releases an extra flash of zest and a slightly floral lilac nuance often tied to terpinolene-rich chemotypes. Many users describe the jar note as bright and invigorating even before consumption.
During combustion or vaporization, the nose shifts toward pine-and-incense with a candied lemon finish. A peppery warmth can appear at the back of the palate, consistent with caryophyllene. With proper cure, sulfurous off-notes are minimal, and the aroma remains focused and layered. Over-drying can mute the top notes, so maintaining cure humidity is key to aroma retention.
Storage influences aroma integrity over time. At 58% to 62% RH and in light-proof containers kept below 21 degrees Celsius, top notes remain vivid for several months. Exposure to heat, oxygen, and UV degrades monoterpenes quickly, reducing citrus intensity first. Airtight storage with minimal headspace helps preserve the cultivar’s signature brightness.
Flavor and Consumption Experience
On the palate, Amnesia Amazon Haze delivers crisp lemon-lime peel over a pine-and-incense mid-body with a faintly sweet herbal finish. Some expressions show a mango-like or passionfruit hint, particularly on the exhale, giving the impression of tropical zest. The smoke can be smooth if the cure is dialed, with a light caryophyllene spice at the finish. Overall, the flavor echoes the aroma with a clear, citrus-forward arc.
Vaporization highlights the top-end terpenes and offers a cleaner read on the profile. Many users find flavor fidelity strongest in the 175 to 190 Celsius range, where volatile monoterpenes remain intact and pronounced. Pushing temperature to 195 to 205 Celsius increases vapor density and potency delivery but can wash out delicate citrus and floral notes. Adjusting temperature across a session can balance flavor and effect.
Combustion presents a sturdier pine-incense core and a more noticeable peppery warmth. A white to light gray ash typically indicates a clean finish and proper dry and cure, which supports smoother flavor. Over-fertilization and poor flush or fade can leave a harshness that obscures the citrus top notes. Experienced consumers often prefer a slow, even burn to savor the layered haze character.
Edibles and tinctures translate the terpene signature less directly but preserve the chemotype’s energetic tone. Citrus-forward tinctures can be paired with limonene-rich natural flavorings to echo the cultivar’s character. With ingestible forms, the onset is slower and the peak duration longer compared to inhalation, emphasizing the importance of patient titration. Flavor aside, the experiential arc remains uplifting for many users.
Cannabinoid Profile and Potency
Amnesia Amazon Haze trends THC-dominant, consistent with Amnesia-descended hybrids. Across Haze-forward cultivars in legal markets, lab-tested THC commonly falls between 16% and 24% by dry weight, or 160 to 240 milligrams per gram of flower. CBD typically measures low, often below 1%, with CBG sometimes registering in the 0.2% to 1.0% range. Total cannabinoids frequently surpass 20% in well-grown, resinous cuts.
Because the breeder’s heritage listing includes ruderalis, some seed lines may prioritize shorter cycles at a modest trade-off in peak potency relative to long-season photoperiods. In autoflower-leaning phenotypes, THC concentrations in the 15% to 20% range are common in commercial runs when environmental and nutritional variables are optimized. Photoperiod expressions, when allowed a full 9 to 11 weeks of bloom, can push toward the upper end of the typical haze range. Phenotype selection and dialed cultivation practices strongly influence these outcomes.
Potency perception is a function not only of THC percentage but also of terpene composition and minor cannabinoids. High-limonene and terpinolene profiles are frequently reported to feel more stimulating and clear at identical THC percentages compared to myrcene-heavy chemotypes. The synergy between THC and terpenes, often called the entourage effect, modulates subjective intensity. As a result, a 18% THC batch with 2.0% total terpene content can feel more vivid than a 22% sample with muted terpenes.
For consumers, translating lab percentages into dosing can be practical. A 0.25 gram inhaled portion at 18% THC contains roughly 45 milligrams of THC, though actual systemic delivery is lower due to combustion or vaporization losses. Beginners generally do better with one or two small puffs, while experienced users may prefer short, spaced draws to gauge the effect. For edibles derived from the strain, 2.5 to 5 milligrams THC is a prudent first step with a two-hour wait.
Lab analytical methods, such as high-performance liquid chromatography for cannabinoid quantification and gas chromatography for terpene profiling, underpin these data ranges. Variability arises from cultivation conditions, harvest timing, and post-harvest handling. Consistency improves with pheno selection, environmental control, and standardized curing protocols. In all cases, interpreting potency alongside terpene content yields a fuller picture of the cultivar’s strength and character.
Terpene Profile and Minor Compounds
Amnesia Amazon Haze frequently presents a terpinolene- and limonene-forward terpene stack, with supportive myrcene and beta-caryophyllene. In Haze-dominant hybrids, total terpene content commonly ranges between about 1.5% and 3.5% by dry weight when grown under high-intensity light with good nutrition and careful curing. Within that total, terpinolene often lands between roughly 0.3% and 1.0%, limonene 0.2% to 0.6%, and myrcene 0.2% to 0.8%, though expression varies by phenotype. Beta-caryophyllene and humulene typically trail as secondary contributors, adding spice and wood.
Ocimene shows up in a portion of haze lines and may contribute to the sweet herbal and tropical edges perceived in some expressions. Linalool occasionally registers at modest levels, providing light floral undertones and relaxation synergy even in sativa-leaning strains. These compounds interact to shape the cultivar’s crisp citrus and pine-lilac identity. Their presence helps explain why the aroma feels both bright and structured.
Minor cannabinoids like CBG can appear at measurable levels, especially in plants harvested slightly earlier in their maturity window. While THC dominates the psychoactive picture, the ratio of minors to majors can subtly affect smoothness and perceived clarity. For example, a sample registering 0.6% CBG may feel fractionally steadier than an otherwise identical batch at 0.2% CBG. Such nuances become noticeable to experienced consumers.
Environmental factors such as light intensity, spectrum, temperature, and harvest timing materially influence terpene expression. High nighttime temperatures can volatilize monoterpenes prematurely, lowering citrus intensity by harvest. A controlled dry at 18 to 21 degrees Celsius and 55% to 62% RH preserves these volatiles in the cure. Glass storage with minimal headspace helps retain the top notes over time.
Experiential Effects and User Reports
The experiential arc is classic haze: fast, bright, and mentally engaging. Many users report an initial rush of citrus-sparked euphoria that transitions into clear-headed motivation. Focus and sociability tend to increase, with music and creative tasks gaining a felt lift. The strain is commonly chosen for daytime sessions.
Physically, the body load is light to moderate, reflecting the sativa-dominant ancestry. Some phenotypes offer a gentle neck-and-shoulder relaxation after the initial mental rise. The finish can feel clean and non-sedating, especially at modest doses. Many users find the comedown short and functional.
Onset and duration vary by route. Inhalation typically produces noticeable effects within 1 to 3 minutes, with a main peak around 15 to 30 minutes and a tail that lasts 2 to 3 hours. Oral ingestion starts in 30 to 90 minutes, peaks between 2 and 4 hours, and can last 6 hours or more. Set, setting, and nutrition status strongly influence the experience.
Sensitive users or those prone to anxiety should approach higher doses cautiously. The same citrus-terpinolene sparkle that energizes many can edge into raciness in others, particularly above 10 to 15 milligrams of inhaled THC equivalents. Staying hydrated, pacing intake, and adding a small snack can help ground the experience. A calm environment and measured dosing greatly improve outcomes.
Tolerance patterns resemble other THC-dominant sativas. Frequent users may find subjective potency drops over a week of daily use, then rebounds after a short break. Rotating with different terpene chemotypes can keep the profile feeling fresh. As always, personal biology and context shape the response.
Potential Medical Applications and Considerations
While not a medical product, Amnesia Amazon Haze’s chemotype suggests potential utility for certain symptom profiles based on user reports and general cannabinoid science. The uplifting, limonene-rich aroma and THC dominance are often sought for low mood, lethargy, and motivational deficits. Light body ease with a clear mental effect may also suit daytime discomfort that benefits from distraction and engagement. Individuals frequently cite productivity and creative flow as qualitative benefits.
Appetite stimulation is a recognized effect of THC, and this cultivar is no exception. For those dealing with situational appetite loss, small inhaled doses before meals can be helpful. The bright terpene profile may counteract nausea in some individuals, though responses vary considerably. Controlled, low-dose trials help establish a personal baseline.
Regarding pain, the strain’s caryophyllene content could provide mild anti-inflammatory and analgesic support. This effect, while not dramatic, can complement the cognitive shift that recontextualizes discomfort. Neuropathic pain sometimes responds better to THC-forward profiles than purely CBD-dominant options, though optimal ratios are individual. A dual approach with topical cannabinoids can add local relief without increasing psychoactivity.
Anxiety responses are bidirectional with THC. For some, limonene-forward profiles paired with small doses can feel bright and mood-lifting. For others, higher doses may provoke unease or racing thoughts. Starting with 2.5 milligrams THC equivalents and slowly titrating allows users to gauge benefit while minimizing adverse effects.
Safety considerations include the usual cautions around impairment, interactions, and personal health context. Avoid driving or operating machinery after consumption. Those with cardiovascular concerns should note that THC can transiently increase heart rate and reduce blood pressure, particularly at onset. As always, individuals should consult a qualified clinician for personalized advice, especially when combining cannabinoids with prescription medications.
Comprehensive Cultivation Guide
Because R-KIEM Seeds lists the heritage as ruderalis, indica, and sativa, growers should confirm whether their specific pack is autoflowering or photoperiod. Autoflower-leaning expressions can be run at 18 hours of light from seed to harvest, often finishing in 10 to 13 weeks total. Photoperiod expressions typically veg under 18 hours and bloom under a strict 12 hours dark cycle for 9 to 11 weeks of flower. Plan your nutrient schedule and canopy strategy accordingly to hit the desired harvest window.
Environment targets follow best practices for haze-forward hybrids. Keep daytime temperatures around 24 to 28 degrees Celsius in veg and 22 to 26 degrees Celsius in flower, with a 2 to 4 degree drop at night. Relative humidity of 65% to 70% in seedlings, 55% to 60% in veg, and 40% to 50% in flower supports healthy respiration and mitigates botrytis risk. Vapor pressure deficit in the 0.8 to 1.2 kPa range during mid flower balances stomatal opening and disease pressure.
Light intensity drives yield and terpene synthesis. Aim for a PPFD of 300 to 400 micromoles per square meter per second in early veg, 600 to 800 in late veg, and 900 to 1100 in mid flower for photoperiod lines, easing to 800 to 950 in late flower to limit foxtailing. Autoflower phenotypes respond well to 18 hours of light at a daily light integral near 35 to 45 mol per square meter in late flower. Keep diodes or lamps at manufacturer-recommended distances and watch leaf posture for early signs of excess.
Media choices include quality peat-based soil mixes, coco coir blends, and hydroponic systems. In soil, target a pH of 6.2 to 6.8; in coco and hydro, 5.8 to 6.2 usually optimizes nutrient availability. Electrical conductivity near 1.2 to 1.6 mS per centimeter in mid veg and 1.8 to 2.2 mS per centimeter in peak flower suits many haze hybrids. Allow 10% to 20% runoff in container grows to prevent salt accumulation.
Nutrition should be balanced and progressive. Provide ample nitrogen through early veg, then taper slightly at the flip to encourage flowering signals. Potassium and phosphorus demand ramps in weeks 3 to 7 of bloom, with secondary elements such as magnesium and sulfur critical for terpene synthesis. Many growers report that sulfur inputs in the 50 to 80 ppm range during mid bloom help enhance the citrus-and-pine bouquet.
Canopy management is key to harnessing the sativa vigor. Low-stress training from the fourth to sixth node spreads the apical dominance and evens light distribution. Photoperiod plants take well to topping once or twice before flip and perform strongly in a screen-of-green layout with 4 to 6 tops per plant. Autoflowers prefer gentle bending and tie-down without heavy topping after day 20 to 25 from sprout.
Watering discipline prevents root stress and preserves terpene quality. Allow the top few centimeters of medium to dry between irrigations while keeping the root zone uniformly moist, not saturated. Root-zone temperatures around 20 to 22 degrees Celsius support oxygenation and nutrient uptake. Enzymes or microbial inoculants can help maintain root health in warm rooms.
Pest and disease management should be proactive. Common greenhouse pests include spider mites, thrips, and fungus gnats; inspect leaf undersides and sticky traps weekly. Beneficials such as Phytoseiulus persimilis for mites and Hypoaspis miles for gnats can integrate with IPM, while foliar sprays should be halted by week 3 of bloom. Good airflow from multiple oscillating fans minimizes microclimates and reduces powdery mildew risk.
Outdoor and greenhouse grows should consider climate suitability. In warm, sunny regions, the cultivar can stretch and fill a trellis with long spears, rewarding the grower with impressive cola length. Cool nighttime temperatures nearing 12 degrees Celsius in late season can slow terpenes and risk moisture buildup in dense tops. Rain protection and morning sun exposure mitigate bud rot, especially during the final two weeks.
Flowering time depends on the line and environment. Autoflower expressions commonly finish in 70 to 95 days from sprout, with the earlier end of the range achievable under stable indoor conditions. Photoperiods often complete in 63 to 77 days of bloom, with some haze-leaning phenotypes needing a few more days for full terpene maturity. Monitor trichome heads and pistil coloration to fine-tune harvest timing.
Harvest timing dramatically shapes the experience. Pulling at predominantly cloudy trichomes, with 5% to 10% amber, preserves the brightest citrus and the most energetic effect. Letting amber climb toward 15% to 20% adds body and a slightly calmer finish at the expense of top-end sparkle. Many haze enthusiasts favor the first window for classic clarity.
Flushing or a well-planned fade improves post-harvest quality. Two plain-water irrigations over the last 7 to 10 days for soil and coco runs can reduce residual salts. In hydro, a 3 to 5 day finish with balanced, low EC solution often suffices. Leaves should pale slightly as nitrogen is remobilized, indicating an orderly senescence.
Drying and curing lock in the cultivar’s aroma. Hang whole plants or large branches at 18 to 21 degrees Celsius and 55% to 62% RH with gentle air exchange, targeting a 10 to 14 day slow dry. Once small stems snap, jar the buds and burp daily for the first week, then weekly for a month. A stable cure brings out the lemon-lime, pine, and floral incense harmonics clearly.
Yield expectations vary by phenotype and technique. Autoflower phenotypes commonly produce 80 to 150 grams per plant indoors under strong lighting, with experienced growers pushing higher. Photoperiod runs in optimized rooms often reach 450 to 650 grams per square meter, with high-PPFD LEDs and CO2 pushing beyond. Training, uniform canopy density, and an even VPD curve are the strongest levers for yield.
Quality control and post-processing matter for resin-rich hazes. Cold, gentle handling preserves trichome heads, especially if producing dry sift or light hydrocarbon extracts. Total terpene recovery is higher when material is frozen quickly for fresh-frozen extraction or when the dry-and-cure are slow and controlled. Even for flower-only use, minimizing handling after cure helps maintain the cultivar’s volatile top notes.
Finally, track data across runs to refine outcomes. Note environmental readings, irrigation volumes, EC and pH logs, and canopy actions tied to week numbers. Yield, terpene results, and potency data provide feedback loops to tune inputs. Over two or three cycles, these records translate into predictable quality that showcases Amnesia Amazon Haze at its best.
