Mamut Haze is a hybrid cannabis cultivar bred by Mamut Seeds, a European breeder known for producing vigorous, garden-friendly varieties. The strain carries a classic indica and sativa heritage, yet leans visibly into the heady, incense-laced personality of the Haze family. Growers and consumers often describe it as a modernized Haze that is more manageable indoors while still delivering the soaring, creative uplift associated with old-world tropical genetics.
In practical terms, Mamut Haze is engineered to balance energy and clarity with a calm physical backbone. Its flowers tend to be elongated and resinous, with a striking calyx-to-leaf ratio that eases trimming. Aromatically, expect bright citrus, herbal spice, and pine-incense notes that intensify as the cure progresses and terpenes stabilize.
While exact lab panels differ by producer, Mamut Haze typically falls into the strong THC category while exhibiting low to moderate CBD. The terpene profile trends toward terpinolene, ocimene, and limonene, complemented by beta-caryophyllene and alpha-pinene. The result is a lively, engaging effect profile that suits daytime productivity for experienced consumers and mindful evening use for those seeking an uplifting mood shift.
As an offering from Mamut Seeds, Mamut Haze exemplifies the breeder's aim for robust growth and balanced effects. It is adaptable to soil, coco, and hydroponic systems with a bloom window that is quicker than many legacy Hazes. For cultivators, it offers reliable returns when canopy and nutrition are dialed in, and for patients and connoisseurs, it delivers a nuanced, fragrant experience.
History and Breeding Background
Haze genetics trace back to 1970s California, where multi-continental sativa lines from Mexico, Colombia, Thailand, and South India were combined. Over time, breeders across Europe stabilized and hybridized Haze with indica lines to shorten the flowering cycle and increase resin density. Mamut Haze represents a contemporary expression of that evolution, blending classic haze-forward aromas and effects with practical cultivation traits.
Mamut Seeds, the original breeder of Mamut Haze, focuses on selections that perform well in indoor tents and Mediterranean-style outdoor climates. Public documentation with an exact release year for Mamut Haze is scarce, which is common among breeder catalogs that evolve over time. Nonetheless, grower accounts consistently place it among modern haze-hybrids that are more manageable than pure equatorial sativas.
The name Mamut hints at vigor and frame, and that focus on plant structure shows up in the stretch and node spacing during the first weeks of flower. Compared with older Hazes that could demand 12–14 weeks of bloom, Mamut Haze is generally faster, helping small-scale growers harvest multiple runs per year. This balance aligns with market shifts toward more terpene-rich, quicker-flowering sativa-leaning hybrids.
As legalization and testing expanded across Europe and beyond, hazy hybrids like Mamut Haze gained traction for their uplifting character without sacrificing yield. Breeders prioritized resin coverage, terpene complexity, and disease tolerance to suit both indoor LEDs and outdoor terraces. Mamut Haze fits squarely in that practical yet aromatic niche.
Genetic Lineage and Ancestry
Mamut Haze is an indica and sativa hybrid whose exact parentage has not been publicly disclosed by Mamut Seeds. That said, its sensory profile and growth traits point strongly toward a Haze-forward backbone stabilized with an indica-leaning counterpart. This combination typically shortens flowering by 1–3 weeks compared with old-school hazes while boosting trichome density and calming the raciest edges.
Classic Haze families derive from mixed landraces, often drawing from Thai, Mexican, Colombian, and South Indian lines. These contribute the hallmark citrus, incense, and spice bouquet, as well as the tall, stretchy growth habit. Indica contributions, often from Afghan or Hindu Kush lines, bring broader leaves in early veg, stockier branching, and denser flower set.
In the field, Mamut Haze behaves like a modern haze-hybrid with a 1.7–2.3x stretch after flip, suggesting a strong sativa influence moderated by indica. The calyx-stacking and moderate internodal spacing in mid-bloom further support a hybridized haze lineage. While the exact cross is proprietary, the phenotypic readout is consistent with stabilized haze hybrids designed for real-world gardens.
For consumers and cultivators, the lack of published parent names is less critical than the observable performance. Reports consistently describe characteristic Haze aromatics and uplift, paired with easier canopy control and faster finishing times. In practice, it functions exactly as a refined haze-hybrid should.
Appearance and Plant Morphology
Mamut Haze develops medium-to-large frames with elongated colas that stack into speared, slightly aerated blooms. The calyx-to-leaf ratio is favorable, with sugar leaves tucking close to the buds and fewer large fans embedded deep in the flowers. Trichome coverage is pronounced by week 6–7 of bloom, with a frosty sheen that intensifies toward harvest.
Coloration trends lime to forest green, often with amber pistils that turn copper or rust as maturity approaches. Anthocyanin expression is uncommon unless exposed to cooler night temperatures during late flower, at which point faint purples may appear on sugar leaves. Buds are firm yet not rock-hard, reflecting the haze influence that favors airflow around the calyxes.
Internodal spacing is moderate in veg and widens during the initial two weeks after the flip to 12 hours of light. Plants typically stretch 70–130 percent, settling into a canopy height of 100–160 cm indoors when trained, and 180–280 cm outdoors in favorable climates. The stems lignify well and respond positively to trellising and low-stress training.
Under high-intensity LED or HPS, colas can fox-tail slightly late in bloom, a trait common to haze-dominant lines when pushed with heat or light. This is usually an aesthetic feature, not a sign of stress, if environmental parameters are in range. Growers who prefer compact buds can moderate PPFD in late flower and keep daytime temps in the 24–26 C range.
Aroma and Bouquet
The aroma of Mamut Haze is distinctly haze-forward, opening with citrus zest and sweet herbal notes. On a fresh grind, terpinolene-driven tones present as pine, wet citrus peel, and a cool, minty lift. As the jar breathes, these top notes bend toward incense, cedar, and a delicate floral sweetness.
Secondary aromatics often include peppery spice and faint mango or tropical hints, consistent with ocimene and limonene support. Beta-caryophyllene may contribute a warm, woody, and faintly clove-like bottom end that rounds the bouquet. When fully cured, the nose becomes more cohesive, blending bright citrus with resinous forest and sandalwood-like facets.
A well-cured sample typically exhibits strong terpenes upon opening, followed by lingering aromatics that persist in the room for several minutes. Total terpene content in high-quality haze-hybrids commonly lands in the 1.5–3.0 percent range by weight, with elite cuts occasionally exceeding 3.5 percent. Storage conditions strongly influence this, and sealed glass with stable temperatures preserves the profile best.
Because terpenes are volatile, aroma intensity can drop by 20–40 percent over a month if jars are opened frequently and humidity swings. Simple practices like 58–62 percent RH packs and cool, dark storage help maintain bouquet. In dispensary contexts, nitrogen-flushed packaging and UV-blocking containers can prolong aromatic integrity.
Flavor and Consumption Notes
On the palate, Mamut Haze delivers bright citrus and pine on the inhale, with a crisp, slightly sweet herbal finish. The exhale leans into frankincense, cedar, and peppery spice, creating a classic haze signature that lingers. Vaporization at moderate temperatures enhances these top notes while minimizing harshness.
At 175–185 C in a dry herb vaporizer, terpinolene and limonene shine, providing a sparkling citrus-pine expression. Raising the temperature to 195–205 C deepens the flavor into spicier, woodier territory as beta-caryophyllene and humulene volatilize more fully. Combustion preserves much of the profile if the flower is well-cured, though the brightest aromatics flash off quickly at higher heat.
Notably, samples with elevated ocimene can show a sweet, almost green-fruit note that reads as mango or pear. Pinene-rich phenotypes tilt the flavor toward resinous pine forests and crisp herbs. Aftertaste is clean and slightly sweet, with an incense echo that can persist for several minutes.
Consumers who prefer smoother draws can dry and cure slowly, targeting 10–14 days of drying at 60 F and 60 percent RH, then 4–8 weeks of jar cure. This schedule preserves monoterpenes while allowing chlorophyll to degrade, reducing grassy notes. Properly cured Mamut Haze is noticeably less harsh and exhibits a more layered flavor profile.
Cannabinoid Profile and Potency
While specific lab results vary by grower and batch, Mamut Haze commonly tests in the mid-to-high THC category typical of haze-hybrids. A practical expectation is 18–24 percent THC by weight, with top-shelf expressions reaching 25–27 percent under optimized cultivation. CBD is generally low, often under 1 percent, though rare phenotypes or deliberate breeding selections can push it to 1–2 percent.
Minor cannabinoids such as CBG often appear in the 0.3–1.5 percent range, with CBC and THCV occasionally showing in trace to low levels. These minor constituents can subtly modulate the experience, sometimes adding clarity or appetite effects. The overall chemotype favors a clear yet potent cerebral lift tempered by a mild to moderate body ease.
Potency perception is influenced by terpene synergy, not just THC percentage. Studies in cannabis analytics show that samples with 2.0 percent or greater total terpenes often feel stronger than their THC percentage alone would suggest. For Mamut Haze, a terpene-rich sample in the 1.8–3.0 percent range can deliver a notably robust onset within minutes of inhalation.
Consistency in cannabinoid expression benefits from environmental stability, nutrient balance, and cultivar selection. Growers who maintain optimal VPD, light intensity, and harvest timing routinely see higher and more stable potency across cycles. Lab testing after each run is the best way to establish a reliable potency profile for a given phenotype.
Terpene Profile and Minor Compounds
Mamut Haze typically expresses a terpinolene-forward or terpinolene-ocimene-limonene triad, a pattern observed in many uplifting haze-like cultivars. In well-grown samples, terpinolene can range from 0.4–1.0 percent by weight, contributing citrus, pine, and a fresh, slightly floral character. Ocimene often follows at 0.1–0.6 percent, adding sweet, green fruit nuances and a light herbal snap.
Limonene commonly lands between 0.2–0.7 percent, offering lemon-lime brightness and enhancing mood-elevating qualities. Beta-caryophyllene is frequently present at 0.15–0.5 percent, contributing woody spice and engaging CB2 receptors for potential anti-inflammatory effects. Pinene (both alpha and beta) can add 0.1–0.4 percent total, providing resinous pine and a subtle sense of mental clarity.
Humulene, linalool, and nerolidol may appear as minor contributors, typically in the 0.05–0.2 percent range each. These bring background notes of hop-like bitterness, lavender-floral calm, and apple-tea softness. The interplay among these compounds creates the balanced yet bright haze signature that defines Mamut Haze.
Total terpene content in artisan-quality flower generally ranges from 1.5–3.0 percent, with meticulous cultivation sometimes pushing higher. Environmental stresses that elevate temperatures or depress humidity late in flower tend to reduce monoterpene retention. Slow drying and careful curing can preserve 70–85 percent of the native terpene content compared with fast, hot drying methods that can cut totals nearly in half.
Experiential Effects and User Reports
Mamut Haze is commonly described as uplifting, clear, and creatively engaging, especially in the first hour. The onset after inhalation typically arrives within 2–5 minutes, with peak effects around 15–30 minutes. Many users report improved focus and a brightened mood without heavy sedation.
As the session progresses, the indica component softens the body and reduces jitteriness that some pure Hazes can induce. This synergy often makes Mamut Haze more approachable for daytime use than racier sativas. Duration of noticeable effects generally runs 2–3 hours for inhalation, with residual aftereffects tapering gently.
At higher doses, some individuals may experience transient anxiety or a rapid heartbeat, a known response to high-THC, terpinolene-rich cultivars. Moderating dose and pairing with a calm environment helps maintain a comfortable experience. For newer consumers, starting low and waiting 10–15 minutes before redosing is prudent.
Vape users often note a clean, functional high that pairs well with music, coding, design work, or outdoor walks. Combustion can feel slightly heavier due to combustion byproducts but still retains the strain's bright mental arc. Across reports, consistent themes include cerebral clarity, light euphoria, and a smooth landing.
Potential Medical Uses and Considerations
The profile of Mamut Haze suggests potential utility for daytime mood elevation, motivation, and mild fatigue. Terpinolene, limonene, and pinene have been studied for alertness and mood-supportive properties, while THC contributes to analgesia and appetite modulation. Patients commonly reach for haze-leaning hybrids for depression-adjacent low mood or anhedonia, though responses vary widely.
Observed benefits in high-THC, terpene-rich hybrids include reductions in self-rated stress and improvements in perceived energy within 30–90 minutes post-inhalation. For pain, Mamut Haze may offer moderate relief, particularly for neuropathic or musculoskeletal discomfort during active hours. Beta-caryophyllene's CB2 activity may contribute to anti-inflammatory effects, especially when combined with humulene.
Mamut Haze is not ideal for severe insomnia because its energizing top-end can delay sleep onset for some. Conversely, it may help with daytime focus or task initiation, particularly in low to moderate doses. Patients sensitive to anxiety should titrate slowly, as terpinolene-forward profiles can feel racy at high doses.
Medical users should track dose, time, and symptom changes to identify personal response curves. Vaporization allows precise titration and may reduce irritation compared with smoking. As always, patients with cardiovascular risk should consult clinicians before using high-THC products due to potential transient increases in heart rate.
Comprehensive Cultivation Guide: Indoors
Indoors, Mamut Haze thrives under full-spectrum LEDs delivering 700–1000 micromoles per square meter per second of PPFD in bloom. Aim for a daily light integral of 35–45 mol per square meter per day during flowering for dense colas and robust resin. In veg, 18 hours of light at 400–600 PPFD with a DLI of 20–30 mol per square meter per day supports tight internodes and healthy roots.
Maintain day temperatures of 24–28 C and nights of 18–22 C during veg, easing to 24–26 C day and 17–20 C night in bloom to preserve terpenes. Relative humidity should track 60–70 percent for seedlings, 50–60 percent in veg, and 40–50 percent in early flower. In late bloom, 35–45 percent RH reduces botrytis risk while keeping VPD in the 1.2–1.5 kPa range.
In soil, target pH 6.2–6.8; in coco or hydroponics, pH 5.8–6.2 is optimal. Electrical conductivity can reside at 1.2–1.6 mS/cm in late veg and 1.6–2.0 mS/cm in mid-to-late bloom, depending on cultivar appetite and light intensity. Many haze-hybrids respond well to a nitrogen-leaner feed from week 4 of flower to encourage terpene expression and reduce leafy regrowth.
Expect a 1.7–2.3x stretch after flipping to 12 hours of light. To manage canopy, top plants once or twice in veg and deploy a single or double trellis net. A Screen of Green approach over 4–8 main tops per plant helps create even light distribution and focuses energy on top-tier flowers.
Flowering time typically ranges 9.5–11 weeks indoors, depending on phenotype and environmental control. Harvest timing should be guided by trichome maturity, aiming for mostly cloudy with 5–10 percent amber for a balanced effect. Under consistent parameters, indoor yields commonly hit 450–600 grams per square meter, with dialed-in grows pushing 650–700 grams per square meter.
Comprehensive Cultivation Guide: Outdoors and Greenhouse
Outdoors, Mamut Haze performs best in temperate to warm climates with low autumn humidity, such as Mediterranean zones. In the northern hemisphere, transplant after the last frost when soil temperatures exceed 15 C consistently. Plants can reach 180–280 cm or more with proper rooting volume and full-sun exposure of 6–8 hours minimum.
Greenhouse cultivation allows season extension and humidity control during bloom. Ventilation and dehumidification are crucial in late flower to prevent botrytis and powdery mildew, especially in coastal or high-humidity regions. Roll-up sides, horizontal airflow fans, and sulfur burners in veg can materially reduce disease pressure.
Organic-rich, well-draining soil with 20–30 percent aeration amendment supports rapid root expansion. A base EC of 0.8–1.2 mS/cm in fertigation and 6.3–6.8 pH in runoff helps maintain nutrient availability. For containerized plants outdoors, 25–50 liter pots are a good starting point, while 75–150 liter containers let the cultivar reach near full potential.
Flowering outdoors typically finishes mid- to late-October in many regions, though warmer climates may finish earlier. Rain shields during the last 3–4 weeks can save entire harvests by preventing water from settling on maturing colas. Outdoor yields vary widely, but well-managed plants often produce 600–1000 grams per plant, with exceptional greenhouse runs exceeding 1.5 kilograms per plant.
Propagation, Training, and Canopy Management
Start seeds in mild media with a low EC of 0.2–0.4 mS/cm and keep temperatures at 24–26 C for speedy germination. Rapid Rooters, rockwool plugs, or a light seed-starting mix all work well. Most seedlings break ground within 2–4 days and establish true leaves by day 7–10.
For mother plants, maintain under 18 hours of light and prune regularly to promote lateral branching. Mamut Haze responds positively to topping, fimming, and low-stress training. Supercropping can be used judiciously to redirect energy and strengthen stems prior to stretch.
In veg, shape plants into flat canopies with 4–8 mains to maximize light use efficiency. Install the first trellis 10–15 cm above the canopy before flipping, and add a second net if stretch is vigorous. Defoliation should be light and targeted, removing large fans that shade key sites without stressing the plant.
During weeks 2–3 of flower, tuck shoots through the net to maintain even spacing of 5–8 cm between tops. Strategic leaf removal around weeks 3–4 improves airflow and light penetration to mid-canopy flowers. Avoid heavy defoliation beyond week 5, as the plant is allocating resources to floral development and resin synthesis.
Nutrition, Irrigation, and Environmental Targets
Haze-leaning hybrids prefer balanced nitrogen early and a steady ramp of phosphorus and potassium through mid-bloom. A practical N-P-K progression might be roughly 2-1-2 in late veg, shifting toward 1-2-3 by weeks 4–7 of flower. Supplement with magnesium and sulfur during bloom, as terpene synthesis relies on adequate sulfur availability.
Maintain calcium levels to prevent blossom-end issues and to fortify cell walls under high light. In coco, a Ca:Mg ratio near 2:1 works well, with 100–150 ppm Ca and 40–60 ppm Mg as a baseline. Silica at 50–100 ppm during veg and early bloom can improve stem rigidity and stress tolerance.
Irrigate to 10–20 percent runoff in inert media to avoid salt buildup. In soil, water to full field capacity and allow a modest dryback, targeting 5–10 percent volumetric water content swings. Automated drip systems with pulse irrigation during peak transpiration stabilize root zone EC and improve consistency.
Environmental targets should track sensible VPD curves. Aim for 0.8–1.2 kPa in veg and 1.2–1.5 kPa in bloom, adjusting RH as temperatures shift. Carbon dioxide enrichment to 1000–1200 ppm during lights-on can increase biomass and yield by 10–25 percent if light, nutrients, and irrigation are also optimized.
Pest, Pathogen, and Stress Management
Mamut Haze, like many haze-hybrids, has moderate tolerance to common pests but benefits from proactive integrated pest management. Scout twice weekly for spider mites, thrips, and aphids, and use yellow and blue sticky cards to monitor populations. Introduce beneficials such as Neoseiulus californicus and Amblyseius swirskii early in veg if you have a history of infestations.
Powdery mildew risk is highest in dense canopies with high humidity swings. Maintain good airflow with oscillating fans and ensure a steady exhaust rate to prevent dead zones. Potassium bicarbonate sprays or biologicals like Bacillus subtilis-based products can be used in veg as preventives, but avoid foliar applications late in flower to protect resin and flavor.
Botrytis (bud rot) is a concern in late bloom, particularly with larger colas in humid conditions. Keep late-flower RH at 35–45 percent and avoid large temperature drops at lights-off that cause dewpoint condensation. Prune interior larf and avoid overhead irrigation to reduce microclimate humidity.
Light and heat stress can induce fox-tailing and terpene loss. Keep canopy PPFD under 1000 micromoles per square meter per second without CO2, and moderate to 900–1100 with CO2 enrichment. If tips bleach, raise lights or reduce intensity by 10–15 percent and check leaf surface temperatures with an IR thermometer.
Harvest, Drying, Curing, and Storage
Target harvest when trichomes are mostly cloudy with 5–10 percent amber for a balanced psychoactive profile. For a brighter, racier effect, harvest at mostly cloudy with minimal amber; for a slightly heavier finish, allow 10–15 percent amber. Pistils alone are not reliable; always check gland heads under magnification.
Before chop, consider a 7–10 day fade with lower nitrogen to improve burn quality and ash color. Some growers implement a 24–48 hour dark period prior to harvest, though evidence for major potency gains is limited. A clean fade paired with optimal environmental control is more impactful than darkness alone.
Dry whole plants or large branches at 60 F and 60 percent RH for 10–14 days with gentle, indirect airflow. This slow dry preserves monoterpenes and prevents case-hardening that traps moisture inside buds. Stems should snap but not shatter when ready for trimming.
Cure in glass jars at 58–62 percent RH, burping daily for the first week and then weekly for the next 3–4 weeks. Expect aroma to bloom significantly by week 2–3 of cure as chlorophyll degrades and terpenes stabilize. Properly cured Mamut Haze maintains flavor and potency for several months when stored in cool, dark conditions.
Yield, Quality Control, and Commercial Insights
Under optimized indoor conditions, Mamut Haze can reliably achieve 450–600 grams per square meter, with elite runs surpassing 650 grams. Outdoors or in greenhouses, single-plant yields often range 600–1000 grams, and top-tier, long-season plants can exceed 1.5 kilograms. These numbers depend on light intensity, plant count, media, and the grower's dialing-in of environment and nutrition.
Quality control hinges on consistent environmental logging and batch-tested analytics. Tracking PPFD, VPD, runoff EC, and bud temperature correlates strongly with repeatable potency and terpene results. Commercial operators who standardize SOPs around these metrics tend to see tighter potency bands and fewer outlier batches.
Trim quality influences consumer perception of haze-hybrids, which already present with slightly more open structure. A clean trim that preserves sugar-leaf resin while removing extraneous leaf improves appearance and bag appeal. Near-dry trimming can help avoid resin smearing, particularly when buds are resin-rich.
In the marketplace, terpinolene-forward profiles are increasingly sought for daytime use, and well-cured batches command higher prices. Clear labeling of harvest date, total terpenes, and dominant terpenes boosts buyer confidence. Batches with total terpenes above 2.0 percent and smooth burn tests tend to move quickly with repeat purchases.
Summary of Key Statistics and Targets
THC commonly 18–24 percent; CBD usually under 1 percent, with occasional 1–2 percent phenotypes. Minor cannabinoids such as CBG often 0.3–1.5 percent. Total terpenes typically 1.5–3.0 percent by weight, led by terpinolene, ocimene, limonene, and beta-caryophyllene.
Flowering time indoors 9.5–11 weeks; outdoor finish mid- to late-October in suitable climates. Stretch 1.7–2.3x after flip. Indoor yields 450–600 grams per square meter; outdoor 600–1000 grams per plant, with greenhouse elites exceeding 1.5 kilograms.
Environmental targets: 24–26 C day in flower, 17–20 C night; RH 40–50 percent in early flower, 35–45 percent late. PPFD 700–1000 micromoles per square meter per second in bloom; DLI 35–45 mol per square meter per day. pH 6.2–6.8 in soil and 5.8–6.2 in coco or hydro; EC 1.6–2.0 mS/cm in mid-to-late bloom.
IPM priorities: prevent powdery mildew and botrytis with airflow, VPD control, and sanitation. Beneficial predators and biological preventives started early reduce pest outbreaks by 50–80 percent compared with reactive sprays. Dry 10–14 days at 60 F and 60 percent RH; cure 4–8 weeks at 58–62 percent RH for optimal flavor and smoothness.
