Atlantis is a modern, mostly indica cultivar developed by Treeology Genetics, a boutique breeder known for precision selections aimed at maximizing terpene expression. The project centered on stabilizing an AK-47 variant that leaned heavier on Afghani influence while elevating a distinct humulene-driven bouquet. This approach preserved the classic hybrid vigor of AK-47 yet redirected the chemotype toward a woodsy, sour profile with calmer body effects.
The strain gained additional visibility through Canadian retail menus, where terpene-forward consumers began identifying it as a humulene-friendly pick. In a Leafly feature on Canadian cannabis strains for people who love humulene, Atlantis was highlighted as a variant of AK-47 with a sour nose, earthy undertones, and sweet wood on the exhale. That description has become a calling card for the cultivar, aligning neatly with Treeology Genetics’ goal of flavor-first breeding.
From a market standpoint, Atlantis emerged during a period when consumers increasingly sought both potency and a distinct aromatic identity. Between 2019 and 2023, legal market data indicate steady growth in consumer interest for strains with unique terpenes beyond the usual myrcene-limonene-caryophyllene trio. Atlantis fit that niche by pairing humulene and caryophyllene with sour top notes, leading to recognizable jar appeal and repeat purchases in stores that carried small-batch drops.
Genetic Lineage and Phenotypic Expression
Atlantis traces directly to an AK-47 lineage, a classic hybrid that itself combines Colombian, Mexican, Thai, and Afghani roots. Treeology Genetics selected for a phenotype that expresses more of the Afghani indica architecture and resin traits while retaining the hybrid’s energetic top-end clarity. The result is a mostly indica plant that shows compact structure and fast finish, yet maintains a balanced, functional effect profile.
Growers frequently note two primary phenotypic lanes in seed runs: a short, stocky pheno with thick calyx stacking, and a slightly taller pheno with more lateral branching. Both phenos typically keep internodes tight and stretch to around 1.5 times their veg height after the flip to flower. The taller expression can exhibit an extra half week to finish and a larger yield ceiling, while the shorter pheno often concentrates terpenes and resin density.
Chemotype expression tends to cluster around high THC with low CBD, consistent with the AK-47 family. Humulene and beta-caryophyllene commonly appear in the top-three terpene slots, with myrcene or alpha-pinene often rounding out the profile. This distribution supports the reported sour-earthy-wood sensory notes and the measured indica-forward body relaxation coupled with a clear head.
Appearance and Structure
Atlantis presents dense, well-formed flowers with a calyx-forward structure and minimal leaf-to-bud ratio, facilitating easy trimming. Buds are often olive to dark forest green with rusty-orange pistils that twist tightly around swollen calyces. High resin output leaves a vivid frost across bracts and sugar leaves, contributing to a sparkling, silvered look under light.
Under magnification, trichomes show a high proportion of cloudy heads at peak maturity, with a typical transition window of 10 to 20 percent amber for those seeking a heavier body effect. Stems are robust, and lateral branches carry weight well, but trellising or staking is recommended to prevent late-flower lean. The plant’s overall structure is compact to medium in height, making it suitable for tents and height-limited spaces.
Packaged flower has strong bag appeal, with tight, conical nugs that retain integrity during curing and transport. Bud density runs on the heavier side, averaging above many sativa-dominant hybrids by dry weight per volume. This density requires careful drying parameters to avoid internal moisture pockets and preserve volatile terpenes.
Aroma Profile
Atlantis is immediately identifiable by a sour front end that leads into damp earth and fresh-cut wood. As the flower breaks apart, a hoppy, herbal character emerges, consistent with humulene being a driver in the profile. The bouquet is rounded by peppery warmth from beta-caryophyllene, which adds depth without overshadowing the sour top notes.
On a cold whiff, expect mineral-tinged sourness with a subtle sweetness that suggests cedar and faint vanilla. When warmed or ground, the aroma blooms toward forest floor and resinous wood, like opening a cedar chest in a brewery’s dry-hop room. This complex interplay often intensifies after a healthy cure of three to six weeks.
Leafly’s Canadian humulene feature references Atlantis as an AK-47 variant with sour and earthy tones and a sweet-wood exhale, a description that matches consumer reports. Terp lovers often describe the aroma as clean yet layered, with no cloying candy notes. As a result, Atlantis appeals to those who prefer old-world, nature-forward profiles over dessert-leaning modern hybrids.
Flavor Profile
The first inhalation typically delivers a sharp, lemon-sour impression that quickly dovetails into earthy resin and fresh wood. As the smoke or vapor settles, a hoppy bitterness appears, reminiscent of noble hops and light pepper. Exhalation brings a sweet wood finish, as documented in retailer and consumer notes, creating a balanced and lingering aftertaste.
In flower vaporizers at moderate temperatures, the flavor flags humulene and pinene early, lending a bright, herbal top with forest-like undertones. At higher temperatures, caryophyllene’s peppery spice steps forward, adding warmth and depth to the finish. Combustion tends to accentuate the woody elements and may introduce a toasted grain nuance.
Compared to many contemporary sweet-leaning hybrids, Atlantis presents a more botanical, savory palate. The profile remains cohesive from the first to the last puff when properly cured at stable moisture activity. Enthusiasts who value terroir-like complexity over confectionary notes will likely find Atlantis unusually satisfying.
Cannabinoid Profile
Atlantis commonly tests as a high-THC, low-CBD cultivar, mirroring much of the AK-47 family. In Canadian and U.S. retail labels for analogous AK-line selections, THC frequently falls between 18 and 24 percent by dry weight, with elite batches occasionally exceeding 25 percent. Early dispensary reports for Atlantis place it in a similar band, while CBD generally remains below 1 percent.
Minor cannabinoids appear in trace to modest amounts, with CBG typically in the 0.1 to 1.0 percent range and CBC present at low fractions. THCV is usually detected at trace levels but can vary by phenotype and environmental conditions. Total cannabinoids often register in the low to high twenties by percentage when cultivation and post-harvest are dialed in.
Potency expression depends strongly on cultivation inputs, harvest timing, and post-harvest technique. For example, maintaining optimal vapor pressure deficit and protecting trichome heads during final two weeks can lift total cannabinoids by several percentage points relative to stressed runs. Likewise, a careful dry and cure can prevent oxidative losses that disproportionately impact THC and terpenes.
Market-wide data from regulated labs show average flower THC commonly clustering around the high teens to low 20s, which situates Atlantis squarely in contemporary consumer expectations. As always, batch labels should guide individual dosing and expectations. Start low and titrate, especially for newer consumers encountering a humulene-forward, potent flower.
Terpene Profile
Atlantis expresses a terpene stack led by humulene and beta-caryophyllene, with myrcene, alpha-pinene, and limonene frequently joining the top tier. In many humulene-forward cultivars, humulene constitutes roughly 10 to 18 percent of the total terpene fraction, translating to about 0.2 to 0.6 percent by weight in terpene-rich batches. While actual values vary by grow, these bands align with reports from Canadian retailers and testing labels for similar chemotypes.
Humulene contributes woody, hoppy, and slightly bitter-herbal facets that frame the sour-earth identity of Atlantis. Beta-caryophyllene, the only common terpene known to bind directly to CB2 receptors, brings peppery spice while potentially modulating inflammation pathways. Myrcene adds cohesion with earthy, musky tones, and at higher loads can soften the overall effect toward relaxation.
Alpha-pinene introduces pine-bright lift and is associated with alertness and bronchodilation, while limonene contributes a clean citrus top that accents the sour opening. The interplay of humulene plus caryophyllene often yields a mature, culinary palate reminiscent of hops, pepper, and roasted wood. This mixed-terpene network provides both distinctive flavor and a well-rounded experiential arc.
Total terpene content in dialed indoor runs often ranges from 1.5 to 3.0 percent by dry weight, with exceptional craft batches occasionally higher. Terpene retention correlates strongly with harvest timing and post-harvest conditions, particularly slow drying at moderate humidity. Given humulene’s volatility, Atlantis rewards gentle handling and low-temperature storage to preserve the top notes.
Experiential Effects
Atlantis is a mostly indica experience with hybrid clarity, offering body relaxation without heavy couchlock at moderate doses. Initial onset for inhaled routes typically arrives within 3 to 10 minutes, bringing a calm, centered headspace and softened muscle tension. Many users report an uplifted but grounded mood that remains functional for conversation, music, or light tasks.
As the session progresses, the body feel deepens, and the shoulders, jaw, and lower back are common areas of perceived relief. High doses can become sedating, leaning into a classic indica arc of tranquility and increased sleep propensity. The duration for inhaled use averages 2 to 3 hours, with a gentle taper rather than an abrupt drop.
Side effects align with common cannabis responses: dry mouth, dry eyes, and, in some sensitive individuals, transient dizziness when taking large hits. Reports of anxiety or racing thoughts appear lower than average for sharper sativa-leaning cultivars, likely due to the grounding terpene mix with caryophyllene and myrcene. As always, set, setting, and personal tolerance strongly shape outcomes.
Compared to dessert-flavored heavy hitters, Atlantis offers a more sophisticated, botanical flavor with a steady, composed high. It pairs well with evening socializing, cooking, documentary watching, or winding down after activity. For daytime use, smaller servings can deliver clarity and calm without heavy sedation.
Potential Medical Uses
While individual responses vary and clinical evidence is evolving, the Atlantis profile suggests potential support in several areas. The humulene and caryophyllene pairing is frequently discussed for inflammation modulation, with caryophyllene known to act at CB2 and humulene studied in preclinical models for anti-inflammatory activity. Myrcene may contribute to analgesic and muscle-relaxing effects, particularly at higher terpene loads.
Consumers often report relief with stress, mild anxiety, and mood stabilization, describing a calm clarity rather than a stimulating buzz. The body-centered relaxation may assist with tension-type headaches, neck and shoulder tightness, and low-back discomfort. For sleep, moderate to higher doses in the evening can promote faster sleep onset for some users.
Beta-caryophyllene’s CB2 activity is a notable focal point in the literature, where it is associated with reduced inflammatory signaling in animal models. Humulene has been evaluated for both anti-inflammatory effects and potential appetite modulation, though outcomes can vary by context and dose. Alpha-pinene’s bronchodilatory reputation and alertness association may add a clear-headed aspect that some patients prefer.
Because THC is typically prominent in Atlantis, it may offer robust analgesic potential but can also increase susceptibility to side effects for new users. Patients should start low, particularly if combining with other sedatives or medications that affect the central nervous system. Medical use should be guided by clinician input, local regulations, and lab-tested product labels.
Comprehensive Cultivation Guide
Atlantis is grower-friendly for intermediate cultivators and scalable for commercial rooms due to its compact structure and consistent bud set. Flowering time runs about 8 to 9 weeks indoors from the 12-12 flip, with some taller phenos needing 9.5 weeks for peak terpene intensity. Outdoors in temperate climates, plan for a mid to late October finish depending on latitude and microclimate.
Vegetative growth is vigorous but controlled, with internodes staying tight and branches responding well to topping and low-stress training. Expect about 1.3 to 1.7 times stretch after the flip, so plan canopy management accordingly. The plant handles SCROG trellising exceptionally well, creating a uniform table of tops for even light distribution.
Environmental targets that perform well include daytime temperatures of 24 to 28 Celsius in veg and 22 to 26 Celsius in flower. Nighttime temperatures around 20 to 22 Celsius help preserve color and reduce stress. Relative humidity works well at 60 to 65 percent in veg, 45 to 50 percent in early flower, and 38 to 42 percent in late flower, yielding a VPD trajectory near 0.9 to 1.2 kPa.
Atlantis appreciates moderate to high light intensity with PPFD around 600 to 900 micromoles in late veg and 950 to 1200 micromoles in mid to late flower. With supplemental CO2 at 800 to 1200 ppm, expect yield improvements of roughly 10 to 20 percent provided nutrition and irrigation are balanced. Without CO2, keep PPFD closer to 900 to prevent light stress and stomatal closure.
Nutrient demands are balanced, leaning slightly nitrogen-hungry in early veg and potassium-forward in late flower. In coco or hydro, target a feed EC of 1.6 to 2.0 mS per centimeter in veg and 2.0 to 2.4 mS per centimeter in mid to late flower, with runoff EC monitored for salt accumulation. Maintain pH around 5.8 to 6.0 in coco and 6.3 to 6.8 in soil to optimize macro and micronutrient uptake.
Watering strategy should favor frequent, smaller irrigations to keep root zone oxygen high and avoid media oversaturation. In soil, allow the top inch to dry before re-watering; in coco, water to 10 to 20 percent runoff when pots lose 40 to 60 percent of their saturated weight. Automated drip with pulse irrigation can maximize consistency and terpene expression.
Training responds well to a mainline or manifold with two to four toppings to build an even canopy. Defoliation should be moderate: clear interior fans that shade bud sites, but avoid overly aggressive leaf removal in weeks two to three of flower to prevent stress. Lollipopping lower third of branches improves airflow and pushes energy into the main tops where Atlantis really shines.
Yield potential indoors averages 450 to 600 grams per square meter under competent LEDs, with dialed, CO2-supplemented rooms able to exceed 600 grams per square meter. Outdoors, healthy plants in 100 to 200 liters of amended soil can produce 600 to 900 grams per plant, assuming long, dry autumns. Bud density is high, so late-season rain and dew management are crucial to avoid botrytis.
Integrated pest management should be proactive. Sticky cards, weekly scouting with a loupe, and preventative biologicals like predatory mites for spider mites and thrips provide strong insurance. Foliar sprays should be avoided after week two of flower; instead, use beneficials and environmental control to keep pests below threshold levels.
Atlantis prefers good airflow because its flowers pack on weight and resin. Provide 0.5 to 1.0 room air exchanges per minute and a multi-fan array to eliminate dead zones within the canopy. Temperature differentials of 3 to 5 Celsius between day and night can help maintain tight internodes and minimize stretch while preserving terpenes.
Harvest timing is best determined by trichome observation rather than calendar days. For a balanced effect, harvest when most heads are cloudy with 5 to 15 percent amber; for heavier indica effects, allow 15 to 25 percent amber. Brix monitoring and terpene intensity on stem rub can corroborate peak maturity in the final week.
Drying should target 15 to 18 Celsius at 58 to 62 percent relative humidity for 10 to 14 days, depending on bud density and branch thickness. A slow dry preserves humulene and the cedar-wood note for which Atlantis is known. Water activity should settle in the 0.55 to 0.62 range before long-term curing to reduce risk of mold while maintaining pliability.
Curing in airtight containers at 58 to 62 percent humidity for an additional 2 to 6 weeks smooths the smoke and intensifies the sweet-wood finish. Burp jars daily during the first week, then taper to every few days as moisture homogenizes. Store finished flower in opaque, airtight containers at cool temperatures to minimize terpene loss; every 10 Celsius increase can roughly double oxidation rates.
For extraction, Atlantis’s resin structure performs well in both hydrocarbon and solventless processes. Hashmakers report strong yield potential from the taller pheno with pronounced calyx stacking. Keep wash temperatures cold, and consider a 90 to 120 micron bag for a balance of yield and quality in ice water hash.
From a selection perspective, phenohunters looking for the humulene-forward expression should favor plants that show woody, herbal aromatics in late veg stem rubs. In flower, seek the pheno that carries sour snap with deep wood and pepper when buds are gently warmed between fingers. These sensory cues often track with the cultivar’s signature effect and flavor arc.
