Written by Ad OpsOrigins and Breeding History of Gelauto N°33
Gelauto N°33 is an autoflowering interpretation of the celebrated Gelato #33 phenotype, purpose-bred by Mephisto Genetics. Mephisto is widely regarded as a top-tier autoflower house, frequently highlighted in industry roundups for quality and innovation. Leafly’s expert spring/summer 2023 autoflower report specifically name-checks Mephisto among the seed makers setting the standard for modern autos. Against that backdrop, Gelauto N°33 represents a logical evolution—capturing the dessert-like character of Gelato #33 in a compact, automatic package.
The original Gelato #33, sometimes nicknamed Larry Bird, rose to prominence in California in the late 2010s. It is a phenotype of the Gelato line created by the Cookie Fam, derived from Sunset Sherbet and Thin Mint GSC. Its acclaim came from dense, resinous flowers and a terpene profile anchored by caryophyllene with bright limonene and grounding myrcene. Translating that signature into an autoflower required careful selection to preserve flavor and potency.
Mephisto’s approach across their catalog involves stabilizing autoflower traits without sacrificing chemotype fidelity. That means repeated filial generations to lock in the ruderalis-driven auto-flowering gene and calm any unwanted variability. In practical terms, Gelauto N°33 was likely refined over several cycles to capture the Gelato #33 sensory fingerprint, growth structure, and resin output. Modern autos often match photoperiod potency due to such rigorous selection.
Autoflower conversions typically aim for seed-to-harvest timelines of 70–90 days while upholding the parent strain’s attributes. For a dessert strain like Gelato #33, the priorities are layered sweetness, creamy citrus, and a pepper-spice bottom note, alongside high THC potential. Gelauto N°33 maintains that emphasis while adding the convenience of a fixed life cycle that ignores photoperiod triggers. This makes it ideal for small spaces, perpetual harvests, and first-time growers.
The name Gelauto N°33 nods to both lineage and phenotype specificity. The “33” signifies the phenotype pedigree, while “Gelauto” signals its automatic growth behavior. In markets where short seasons and limited sun threaten photoperiod finishes, this adaptation markedly improves the odds of harvesting before weather turns. It is also a strong candidate for light-deprived balconies, tent grows, and multi-run, year-round indoor schedules.
Genetic Lineage and Autoflower Conversion
Gelauto N°33 draws its core genetics from Gelato #33, a cross of Sunset Sherbet and Thin Mint GSC. This parentage is renowned for dessert-forward terpenes and trichome density, traits that are typically heritable with careful selection. To achieve autoflowering behavior, breeders introduce Cannabis ruderalis genetics, often through a stabilized auto donor line. The result is a ruderalis/indica/sativa composite that flowers by age rather than light cycle.
In the autoflower world, maintaining chemovar integrity requires balancing three forces: potency retention, terpene fidelity, and uniform growth. Ruderalis contributes the auto trait, cold hardiness, and a compact frame, but historically it could dilute cannabinoid levels. Modern selections have narrowed that gap, with numerous autos matching the 18–25% THC brackets of elite photoperiod cuts. Gelauto N°33 slots into this trend by preserving the Gelato #33 chemotype while modernizing its agronomics.
Gelato #33 is frequently reported to express dominant caryophyllene with supporting limonene and myrcene. Leafly’s strain profile specifically confirms this terpene ordering for the #33 cut. That aromatic backbone often translates well across breeding projects because the genes governing terpene synthase expression are strongly selected. Mephisto’s track record suggests particular care to retain those enzymatic pathways during autoflower conversion.
The structural influence of Thin Mint GSC in Gelato #33 often shows as dense buds and a strong calyx-to-leaf ratio. Sunset Sherbet adds color potential and the creamy citrus-berry elements. When overlaid with ruderalis, the plant typically compacts slightly, shortens internodal spacing, and accelerates maturation. Growers can expect a mid-sized auto with stacked nodes and solid apical dominance if untrained.
From a chemovar perspective, the genes responsible for peppery beta-caryophyllene, citrusy limonene, and herbal myrcene are among the most conserved across Gelato #33 progeny. Autoflowering does not inherently reduce those enzymes’ throughput once stabilized. As a result, Gelauto N°33 tends to replicate the parent’s aromatics while introducing more predictable scheduling. That genetic consistency is a central value proposition for this line.
Appearance and Morphology
Mature Gelauto N°33 plants typically present as medium-height autos finishing around 60–100 cm indoors, depending on pot size and training. Internodes are relatively tight compared to lankier sativa-leaning autos, a reflection of the indica influence from the GSC side. Lateral branching is vigorous enough to fill a 60–90 cm tent footprint, but not unruly. The canopy often forms a symmetrical crown if given early low-stress training.
Bud structure is dense, with a high calyx-to-leaf ratio that aids trimming and bag appeal. Flowers commonly display lime to forest-green hues, with anthocyanin expression possible under cooler night temperatures near late bloom. Sugar leaves can take on violet streaks if temperatures are kept 3–5°C cooler at night in the final two weeks. Trichome coverage is pronounced, often giving buds a sugared, frosty finish.
Pistils begin cream to light peach and mature to a burnt orange or amber as harvest approaches. The resin heads are medium to large, with a mix of capitate-stalked glandular trichomes indicative of high THC potential. Under magnification, a heavy blanket of cloudy trichomes with some amber suggests peak ripeness. The resin density makes Gelauto N°33 a suitable candidate for solventless pressing and dry sift.
Leaf morphology tends toward broad, slightly serrated blades in veg, tightening and canoeing modestly under high light. Ruderalis influence confers a sturdy petiole and thicker stems relative to plant size. This contributes to good nug support without extensive staking in moderate-yield setups. In high-yield scenarios, simple yoyos or a light trellis helps prevent lateral flop.
Overall, visual appeal is a core strength, with “dessert strain” aesthetics that mirror the parent. Expect a photogenic cure with high bag appeal due to a developed frost and tight nug formation. The bud density stands up well in jars without compression if dried and cured properly. These features make it attractive for both headstash and small-batch craft menus.
Aroma
Aroma in Gelauto N°33 skews toward the Gelato #33 signature: creamy citrus, sweet berry, and a peppery undercurrent. The dominant terpene is typically beta-caryophyllene, which delivers the black pepper and warm spice accents. Leafly’s profile for Gelato #33 lists caryophyllene as most abundant, followed by limonene and myrcene, and that ordering often carries through in this auto. The first impression is sweet and dessert-like rather than pine-forward or fuel-heavy.
In veg, the plant emits a mild sweet-herbal scent, intensifying substantially from week 4–6 as preflowers develop. By mid-bloom, the terpene output becomes room-filling in enclosed spaces, requiring carbon filtration. Peak intensity commonly arrives in the final 10–14 days, when limonene brightens the top notes and myrcene rounds the base. This staging is consistent with trichome maturation patterns tracked by many growers.
On a live rub, expect zesty orange peel and sugared berry intertwined with cream. Dry-in-jar aromatics lean toward gelato ice cream with a slight minty-cocoa echo inherited from Thin Mint GSC. Some phenotypes will show a faint earthy bread note, hinting at humulene and possibly farnesene as minor contributors. These variations remain within the Gelato #33 aromatic umbrella.
Terpene intensity can be influenced by environmental controls, especially temperature, VPD, and post-harvest handling. Maintaining day temperatures of 24–27°C and nights 20–22°C in late bloom helps preserve volatile monoterpenes like limonene. A gentle, extended dry at 60% relative humidity and 18–20°C for 10–14 days retains more linalool and esters. Proper curing further integrates the peppered cream sweetness that defines the profile.
Compared to gas-heavy cultivars, Gelauto N°33 projects a friendlier, confectionary bouquet. It is social-setting friendly, less likely to dominate a room with diesel or skunk. However, the caryophyllene spice keeps it from cloying, lending balance and sophistication. The result is a nuanced, dessert-forward aroma that rewards close inspection.
Flavor
The flavor carries through faithfully from the nose, emphasizing citrus cream, berry syrup, and a peppery snap on the exhale. Limonene and related citrus terpenes contribute perceived sweetness and a bright lift across the palate. Beta-caryophyllene provides a warm, pepper-spice edge that lingers without harshness. Myrcene adds a gentle herbal depth and smooths the mouthfeel.
On a dry pull, you may notice orange sherbet and vanilla wafer hints, a nod to the Sunset Sherbet influence. Combustion at lower temperatures preserves the cream and citrus zest while minimizing bitter phenols. Vaporization between 175–190°C often showcases the full dessert spectrum without overwhelming spice. Raising temperature above 200°C accentuates the pepper and cocoa-mint undertone.
Flavor stability is best achieved through a slow cure and conservative humidity control. Curing in the 58–62% RH range for at least 3–4 weeks integrates the top and base notes. At this stage, the exhale frequently reveals a minty-chocolate whisper from the GSC lineage. The interplay of sweet cream with spice gives Gelauto N°33 a sophisticated finish.
Different consumption methods will emphasize different components of the flavor stack. Joints and convection vaporizers highlight limonene brightness and the gelato-like sweetness. Glass rigs or pipes tend to amplify caryophyllene’s pepper, especially at higher temperatures. Pressed rosin from this cultivar can skew toward sweet orange custard with a crack of pepper.
Compared to photoperiod Gelato #33, the best examples of Gelauto N°33 stand shoulder to shoulder on flavor when grown and cured optimally. Any minor differences are typically due to grow conditions rather than genetics. Because autos move quickly, dialing in nutrient strength and dry-back is crucial to prevent flavor-sapping stress. When handled well, the flavor is immersive and true to type.
Cannabinoid Profile
While cannabinoid output varies by phenotype, environment, and lab method, Gelauto N°33 fits within the modern auto’s high-potency bracket. Photoperiod Gelato #33 commonly lands between 18–25% THC in published lab results, with CBD often below 1%. Advanced autos now routinely reach similar ranges, with Gelauto N°33 frequently reported in the upper teens to mid-20s for THC when dialed in. Occasional outliers may test slightly higher, but consistent mid-20s require optimal cultivation.
Total cannabinoids can exceed 20% when grown under strong light with proper VPD and nutrition. Many growers target PPFD of 600–900 µmol/m²/s for quality-focused autos, achieving solid potency without overdriving metabolism. In such conditions, THC-dominant chemotypes typically present minimal CBD, often 0.1–0.8%. Trace CBG values are common, sometimes ranging 0.2–1.0% in mature, well-cured flower.
The ratio profile is THC-dominant, with minor cannabinoids like CBC and CBN present at low levels influenced by age and cure. Allowing additional amber trichome development can slightly raise CBN via THC oxidation, increasing sedative properties. However, delaying harvest risks terpene loss and diminished head effects. Most growers target a cloudy-dominant trichome field with 5–15% amber for balanced outcomes.
Extraction potential is strong due to trichome coverage and resin head size. Solventless yields often fall in the 15–25% return range on select phenotypes, assuming careful harvest timing and cold handling. Solvent-based extractions can capture a wider cannabinoid spectrum along with the dessert terpene profile. For consumers seeking portable formats, live rosin from this cultivar can be particularly flavorful.
Because cannabinoid expression is environment-sensitive, it is useful to pair lab numbers with cultivation notes. Keeping leaf temps steady, avoiding nitrogen toxicity in late bloom, and maintaining moderate EC levels help preserve resin biosynthesis. Underfeeding late can reduce THC and terpene outputs due to stress. With correct inputs, Gelauto N°33 showcases the high-potency promise of modern autos.
Terpene Profile
Gelauto N°33 inherits the Gelato #33 terpene hierarchy documented by Leafly, with caryophyllene as the most abundant terpene, followed by limonene and myrcene. Beta-caryophyllene contributes a pepper-spice aroma and may interact with CB2 receptors, which some research associates with anti-inflammatory signaling. Limonene delivers bright citrus notes and is often linked to mood elevation in survey data. Myrcene adds an herbal, musky ballast and can impart a perception of relaxation.
In terms of magnitude, total terpene content in well-grown dessert cultivars often falls between 1.5–3.5% by weight. Within that, caryophyllene might commonly range around 0.3–1.0%, limonene 0.2–0.8%, and myrcene 0.2–0.7% depending on phenotype and environment. These ranges are typical across Gelato-leaning lines rather than unique to this cultivar. Minor terpenes such as linalool, humulene, farnesene, and ocimene appear variably and add complexity.
Environmental controls play a measurable role in terpene retention and expression. Nighttime temperatures kept 3–5°C cooler than day temps can support anthocyanin expression and preserve monoterpenes. Drying at approximately 18–20°C and 55–62% RH for 10–14 days reduces volatilization of limonene and ocimene. Excessive heat during dry can drive terpene losses exceeding 25%, based on general post-harvest studies of aromatic crops.
Nutritional balance, particularly sulfur availability, contributes to terpene biosynthesis as sulfur forms part of key amino acids and coenzymes. Maintaining adequate micronutrient levels avoids bottlenecks in enzymatic pathways that produce monoterpenes and sesquiterpenes. Overfeeding nitrogen in late bloom can mute terpene intensity and wash out flavor. Balanced feed strategies result in sharper citrus, deeper spice, and a more layered bouquet.
For consumers, the terpene profile translates to consistent sensory markers: sweet citrus cream up front, peppered spice through the mid-palate, and a gentle herbal finish. The caryophyllene-limonene-myrcene trio provides both contrast and cohesion. This profile also aligns with reported effects that combine mood elevation with body composure. It is a terpene arrangement that has made Gelato #33 and its derivatives enduringly popular.
Experiential Effects
User reports for Gelato #33 describe an uplifting yet composed experience, and Gelauto N°33 follows a similar arc. The onset tends to be quick, with a bright, mood-forward lift likely tied to limonene and high THC. Beta-caryophyllene’s presence often grounds the experience with body comfort and a warm, relaxing baseline. Many users find it suitable for afternoon and early evening when they want euphoria without couchlock.
At moderate doses, the headspace is clear and social, complementing creative tasks or conversation. Music and flavor appreciation are often enhanced, a hallmark of dessert profiles. As dose increases, the body component becomes more pronounced, easing tension and promoting a calm, floaty sensation. The transition from talkative to tranquil is smooth rather than abrupt.
Because THC is dominant, inexperienced users should titrate carefully to avoid overconsumption. Rapid onset can lead to a quick ramp in intensity, particularly when dabbed or vaporized at high temperatures. Side effects can include dry mouth, red eyes, and transient anxiety in sensitive individuals at high doses. Keeping water on hand and lowering intake rate helps manage these effects.
Compared to heavier indica-leaning cultivars, Gelauto N°33 offers a more balanced psychoactive footprint. It typically avoids the heavy sedation that can limit functional use. At the same time, it is not a racey, narrow-focus sativa; the body component is present enough to provide composure. This makes it versatile for both recreational and light functional contexts.
Environment and setting shape the experience noticeably. Calm, low-stress settings tend to foreground the dessert character and creative uplift. High-stimulus environments can magnify intensity, so dosage awareness matters. Overall, it is a celebratory, feel-good cultivar with broad appeal to users seeking flavor-forward euphoria.
Potential Medical Uses
While controlled clinical data on individual cultivars remain limited, Gelauto N°33’s chemotype suggests several plausible therapeutic niches. THC-dominant, caryophyllene-forward profiles are often reported by patients to aid transient stress, low mood, and appetite stimulation. Beta-caryophyllene’s interaction with CB2 is a subject of ongoing research into inflammation and pain modulation. Limonene’s presence aligns with survey-based reports of perceived anxiolytic and mood-elevating effects in some users.
Patients dealing with neuropathic or musculoskeletal discomfort sometimes prefer caryophyllene-rich chemovars for evening relief. The balanced psychoactivity can help reduce rumination while providing body ease. For nausea or appetite loss, THC remains a primary driver, and dessert terpenes may improve palatability and adherence. Myrcene’s sedative-adjacent qualities at higher doses can support wind-down routines.
Potential adverse effects include short-term memory disruption, anxiety at high doses, and orthostatic lightheadedness in predisposed individuals. Patients with a history of panic should start low and slow, ideally in a controlled environment. Those sensitive to THC may consider vaporization at lower temperatures or microdosing strategies. Consultation with a knowledgeable clinician is advisable for patients using cannabis concurrently with other medications.
Form factors can be selected to match therapeutic goals. Vaporizing flower at 175–190°C can provide fast-acting relief with preservation of limonene and linalool. Tinctures or capsules derived from the same chemotype offer longer-duration effects and consistent dosing. Topicals fortified with caryophyllene may support localized comfort without psychoactivity.
As with all patient use, tracking outcomes in a journal helps refine dose, timing, and method. Recording symptom baselines and post-dose changes over two weeks can reveal patterns. Adjustments to cultivar, preparation, or time of day can enhance efficacy. Gelauto N°33’s approachable effects and pleasant flavor often improve adherence for new patients.
Comprehensive Cultivation Guide
Gelauto N°33 performs well in both indoor and outdoor settings, with a seed-to-harvest window typically in the 70–90 day range. As an autoflower, it does not require photoperiod changes to initiate bloom. Most growers achieve best results with 18/6 or 20/4 light schedules, balancing growth vigor and plant recovery. Outdoors, planting after the last frost and targeting peak summer sun dramatically improves outcomes.
Lighting intensity is a key driver of yield and quality. Indoors, aim for a PPFD of 500–900 µmol/m²/s across most of the cycle, adjusting lower (500–650) in early veg and higher (700–900) from mid-bloom onward. This translates to a daily light integral of roughly 30–45 mol/m²/day. Autos can be sensitive to excessive intensity early; ramp light over the first 10–14 days.
Temperature and humidity management should target a vapor pressure deficit (VPD) of 0.8–1.2 kPa in veg and 1.2–1.6 kPa in bloom. Practically, that means 24–27°C day temps with 60–70% RH early, tapering to 24–26°C with 45–55% RH in late flower. Night temps of 20–22°C support terpene retention and color expression. Keeping leaf temperature consistent prevents metabolic shocks that reduce resin production.
Medium choice is flexible: high-oxygen coco blends, light peat-based soils, or living soil all work. For coco or inert blends, target a root-zone EC of 1.1–1.4 in early veg, 1.4–1.8 in mid-veg and early bloom, and 1.7–2.1 in peak bloom, tapering slightly at the end. Maintain a pH of 5.8–6.2 in coco/hydro and 6.2–6.8 in soil. Consistent, moderate feeds outperform sporadic heavy doses.
Pot size influences plant stature and yield. Autos generally thrive in 11–19 L (3–5 gal) containers, with 3 gal favoring compact plants and 5 gal allowing more lateral branching. Direct seeding or early transplant (day 7–10) minimizes root shock that can stunt autos. Fabric pots or air-pruning containers encourage dense, fibrous root systems and improved oxygenation.
Training should be gentle and front-loaded. Low-stress training (LST) from day 14–28 helps open the canopy and distribute light without triggering recovery stalls. Topping is possible on vigorous autos but should be done only once around day 18–21 and only on robust individuals. Defoliation should be light and strategic, removing leaves that block major sites but avoiding aggressive stripping.
Irrigation strategy depends on medium. In coco, frequent smaller irrigations maintain steady moisture and nutrient availability; allow slight dry-backs to promote oxygenation. In soil, water to 10–15% runoff and let the top inch dry between waterings to prevent root rot. Avoid overwatering early—autos dislike soggy media in the first 10–14 days.
Nutrient management benefits from a balanced NPK with micronutrients and sulfur for terpene synthesis. Reduce nitrogen after week 4–5 as the plant transitions to flower to prevent leafy buds and muted terpenes. Supplementing calcium and magnesium (e.g., 0.5–1.0 mL/L Cal-Mag) is often helpful under strong LED lighting. Consider carbohydrate or amino acid supplements judiciously if they fit your regimen, but prioritize base nutrition and environment first.
Integrated pest management (IPM) should be proactive. Sticky cards, weekly leaf scans, and good airflow reduce pest pressure. Biological controls like Bacillus thuringiensis israelensis for fungus gnats or predatory mites for spider mites can be deployed preventively. Avoid spraying oily products after week 3 of flower to prevent residue on trichomes.
Flower development accelerates around day 28–35, with noticeable stacking and resin onset. By day 50–60, trichomes are typically milky with some clear; peak harvest often arrives day 65–80 depending on phenotype and environment. Use a jeweler’s loupe to assess trichome maturity, targeting mostly cloudy with 5–15% amber for balanced effects. Extending to higher amber increases sedative properties but can dull top notes.
Yield expectations depend on conditions, pot size, and training. Indoors, 60–150 g per plant is common for well-grown autos in 3–5 gal pots under efficient LEDs, with dense canopies exceeding 200 g in optimized setups. Per square meter, 400–600 g/m² is a realistic baseline with potential to go higher for experienced growers. Gram-per-watt figures of 0.8–1.8 are typical range posts under mid-to-high efficiency lighting.
Harvest handling strongly influences final quality. Wet trimming can expedite processing but increases oxidation risk; dry trimming preserves aromatics when drying conditions are controlled. Aim for a slow dry at 18–20°C and 60% RH for 10–14 days until stems snap rather than bend. Cure in airtight jars, burping daily for the first week, then weekly for 3–6 weeks, stabilizing at 58–62% RH.
Outdoor cultivation should maximize sun exposure and minimize cold stress. Plant after soil temps reliably exceed 12°C and plan the 70–90 day cycle to finish before cold, wet weather. Autos can be run in succession outdoors, starting a new cohort every 30 days for continuous harvests. Raised beds or 30–50 L containers with living soil produce strong results with low maintenance.
CO2 enrichment can push photosynthesis and yields in sealed rooms. Target 900–1200 ppm CO2 during lights-on when PPFD exceeds 800 µmol/m²/s, combined with adequate temperature and nutrition. Ensure robust dehumidification and air exchange to prevent fungal risk. Without CO2, maintain standard atmospheric levels and do not overdrive light intensity.
Common pitfalls include early overwatering, excessive defoliation, and aggressive topping that stalls autos. Nutrient burn manifests as marginal leaf burn and clawing; reduce EC and flush medium if needed. Conversely, deficiencies show as pale leaves, interveinal chlorosis, or weak stems; adjust feed and pH. Regular, small corrections outperform dramatic swings in inputs.
Dry sift and hash makers will find Gelauto N°33 cooperative due to its gland density. Keep all processing surfaces cold to preserve terpene integrity and prevent greasing. Solventless returns improve when harvesting at peak ripeness with a high proportion of intact, cloudy heads. Properly stored concentrates retain the strain’s citrus cream and pepper profile for months.
Storage of dried flower should be cool, dark, and stable. Temperatures around 16–20°C and RH of 58–62% minimize degradation of THC to CBN and loss of monoterpenes. Avoid frequent jar openings and exposure to light which can accelerate cannabinoid and terpene decay. With good storage, the flavor remains vivid and the effect profile stable for 6–12 months.
