All Gas OG Auto is an autoflowering cannabis variety developed by Humboldt Seed Company, a Northern California breeder known for high-yielding, terpene-rich lines. As an autoflower, it transitions to bloom on its own clock, typically finishing from seed to harvest in about 70 to 85 days under optimal conditions. The strain is a balanced ruderalis/indica/sativa composition, leveraging ruderalis for the automatic flowering trait while preserving the dense structure and gassy terpene profile associated with classic OG lines.
Growers are drawn to All Gas OG Auto for its straightforward cycle and dependable aroma profile. In commercial and home grows alike, autos like this often fit tight production schedules, allowing multiple harvests per year under continuous lighting. The cultivar’s appeal also rests on its potent effect profile, which users commonly describe as calm, heavy, and physically grounding.
Humboldt Seed Company’s autos have aimed to close the historical performance gap between autos and photoperiods. Over the past five years, published breeder reports and aggregated grow logs show modern autoflowers regularly achieving THC in the high teens to low 20s. That improvement accompanies better terpene output too, with well-grown autos frequently testing in the 1.5% to 3.0% terpene range by dry weight.
Beyond personal consumption, All Gas OG Auto has begun to appear in breeding projects due to its resin density and gas-forward bouquet. Seed catalogs and breeder notes regularly cite it as an input parent in crosses that seek OG-like fuel aromas in an autoflower format. Its presence as a contributor signals solid genetic stability and desirable traits that other houses want to capture.
Breeding History and Development
All Gas OG began life in Humboldt Seed Company’s photoperiod catalog and was formerly circulated as Asphalt Plant, a nod to its asphalt-and-diesel nose. Translating it to an autoflower required several generations of backcrossing and selection to introduce ruderalis while maintaining the original terpene fingerprint and yield. The resulting auto is classified as ruderalis/indica/sativa, with selection pressure aimed at cola mass, resin coverage, and a consistent gas terpene ratio.
Breeding for autos typically takes three to five generations to stabilize the flowering time and plant architecture. During this process, breeders often measure uniformity by tracking days to first pistils and harvest windows, seeking variance of less than 10 days per population. Anecdotally, growers of All Gas OG Auto report relatively tight phenotypic spread in height and onset, a sign of targeted selection.
Autoflower adoption has accelerated because it removes the need to flip lighting schedules, allowing 18 or 20 hours of daily light from start to finish. In controlled environments, this translates to higher cumulative photosynthetic photon flux, sustaining compact plants with significant bud density. For cultivators in northern latitudes or short outdoor seasons, autos like All Gas OG Auto can complete cycles before autumn rains, reducing botrytis risk.
The wider market has taken notice of its breeding utility as well. SeedFinder and related strain databases document crosses involving All Gas OG Auto, including a listed Dark Star Auto (Blim Burn Seeds) x All Gas OG Auto combination. That sort of pairing underscores the cultivar’s value as a donor of fuel-heavy terpenes and thick calyx formation in auto formats.
Genetic Lineage and Heritage
All Gas OG Auto reflects a three-part heritage: ruderalis for autoflowering, indica for density and sedative body effects, and sativa for vigor and a touch of mental lift. While its precise parental map is proprietary, its sensory profile places it firmly in the OG family tradition. OG lines are known for an interplay of myrcene, beta-caryophyllene, and limonene, creating the fuel, pine, and earthy notes many connoisseurs prize.
Ruderalis contribution is primarily photoperiod independence and maturation speed. In practice, this means the cultivar initiates flowering around day 21 to day 30 from sprout, regardless of light cycle. That mechanism is governed by day-neutral genetics absent in most indica and sativa backgrounds.
Indica influence shows in the plant’s squat frame, broad leaflets during early growth, and firm bud structure. Many growers note internodal spacing of approximately 3 to 5 centimeters on trained plants, which supports contiguous flower sites. Sativa elements present as lateral branching vigor and the capacity to handle higher light intensities without stress.
The ruderalis/indica/sativa balance also explains the effect profile. Most users describe a rapid physical relaxation coupled with clear-headed calm rather than a racy mental effect. This is typical of OG-descended autos that lean toward body comfort while keeping enough mental clarity for evening social use.
Appearance and Plant Morphology
All Gas OG Auto grows to a medium stature indoors, commonly 70 to 120 centimeters tall in 3 to 5 gallon containers. Outdoors in full sun, single plants can reach 100 to 140 centimeters with a broad, bushy canopy when trained early. The cultivar tends to develop a stout central cola with several strong laterals if low-stress training is applied by week three.
Leaves start wide and deep green, reflecting a moderate nitrogen appetite during the first four weeks. As flowering advances, fan leaves often darken slightly and can show purple hues in cooler night temperatures below 18 degrees Celsius. Resin glands densely coat bracts by week five to week six of flower, giving a frosted appearance that intensifies through ripening.
Calyx formation is compact and stacked, producing spear-shaped colas with firm density. Under proper environmental control, bud firmness rates high, with growers often describing hand-trimmed buds as marble-hard. For a balanced auto, bud-to-leaf ratio is favorable, easing post-harvest trimming workload.
Trichome heads present predominantly cloudy near harvest with a 10% to 20% fraction turning amber, depending on timing. Pistils progress from cream to orange-brown, with high pistil coverage in mid-bloom indicative of active calyx swelling. These visual cues, combined with trichome assessment, help dial in the desired potency and effect skew.
Aroma: The Gassy, Piney Bouquet
The signature aroma is heavy gas layered with pine, earth, and faint citrus. Dry rub of a sugar leaf often releases a diesel kick first, followed by peppery spice from beta-caryophyllene. On broken buds, some phenotypes reveal a sweet backend reminiscent of petrol-coated lemon zest.
Measured terpenes in OG-leaning autos commonly total 1.5% to 3.0% by dry weight, and All Gas OG Auto fits that expected envelope when grown well. The dominant notes are consistent with myrcene-driven earth and caryophyllene’s pepper, anchored by limonene’s bright top note. Subdominant humulene and pinene contribute a dry, woody edge and forest pine nuance.
In flowering rooms, the scent intensity escalates quickly between weeks four and seven. Carbon filtration rated for at least 1.5 to 2 times the tent’s cubic volume per minute is advised to manage odor. Outdoors, prevailing winds can carry the bouquet across property lines, so growers should plan for discretion.
Post-cure aroma tightens into concentrated fuel with layers of tar, pine resin, and zesty rind. A well-executed 21 to 28 day cure amplifies the volatile fraction, with many users noting the jar reek spikes after the second week. Mishandled drying can dull the top notes, so slow, cool curing is critical for preserving the full bouquet.
Flavor and Smoke/Vapor Profile
The flavor follows the nose with dominant fuel and pine, backed by earthy undertones. On inhale, expect a sharp diesel bite that softens into pepper and wood. Exhale commonly brings out lemon-pine cleaner and a faint sweet tar finish.
When vaporized at 175 to 190 degrees Celsius, the terpene layers separate more clearly. Limonene and pinene pop early, delivering citrus and pine zest, while caryophyllene and humulene extend the peppery-woody trail as temperature rises. At lower temps, the profile tastes brighter; at higher temps, the gas and spice deepen.
Combustion can deliver a heavier mouthfeel due to resin density, especially in tightly packed joints. Properly flushed plants and a slow dry reduce harshness, yielding a clean burn with light gray ash. Many users prefer glass or convection vaporizers to appreciate the nuance while minimizing throat bite.
Edible infusions capture a different facet of the flavor, often translating to herbal-citrus with a faint diesel echo. Terpene preservation in infusions depends on extraction method and decarboxylation temperature curve. Cold ethanol and careful decarb protocols can retain a more complex flavor footprint compared to hot oil infusions.
Cannabinoid Profile and Potency
Modern autoflowers frequently clock THC in the 18% to 24% range, and All Gas OG Auto is commonly reported in the high teens to low 20s when dialed in. CBD typically remains low, often 0.1% to 0.8%, characteristic of THC-dominant OG progeny. Minor cannabinoids such as CBG and CBC may register between 0.1% and 0.5% combined in well-developed samples.
In quantitative terms, a 20% THC flower contains roughly 200 milligrams of THC per gram before decarboxylation. After decarb, THC potency by mass remains comparable, but bioavailability changes based on consumption method. Vaporization commonly yields efficient delivery with relatively fast onset compared to oral routes.
Dose-response curves for THC-dominant strains show steep early effects with notable individual variability. Novice consumers often find 2.5 to 5 milligrams of inhaled THC-equivalent sufficient, while experienced users might prefer 10 to 20 milligrams per session. For edibles, first-time doses around 2.5 to 5 milligrams THC are prudent due to slower onset and longer duration.
Lab variability should be kept in mind, as inter-lab differences of plus or minus 2% absolute THC are not unusual across states. Post-harvest factors such as drying temperature and storage can also affect measured potency over time. When stored at 16 to 20 degrees Celsius and 58% to 62% relative humidity, potency and terpenes degrade more slowly, preserving the intended profile.
Terpene Profile and Chemistry
The terpene signature is OG-forward, with myrcene, beta-caryophyllene, and limonene forming the core. Typical ranges for well-grown samples are myrcene at 0.4% to 1.2%, caryophyllene at 0.3% to 0.8%, and limonene at 0.2% to 0.7% by dry weight. Secondary contributors often include humulene at 0.1% to 0.3%, alpha-pinene at 0.05% to 0.25%, and linalool at 0.05% to 0.20%.
Myrcene is associated with earthy, musky notes and may modulate perceived sedation in concert with THC. Beta-caryophyllene, a dietary terpene and CB2 receptor agonist, contributes pepper and depth while potentially influencing body comfort. Limonene adds citrus brightness and is often linked to mood elevation in user reports.
Humulene supports woody dryness and may balance richness with a crisp edge, frequently present alongside caryophyllene due to shared biosynthesis pathways. Pinene conveys pine forest aromatics and can lend perceived clarity to the effect at modest concentrations. Linalool, though lower in quantity, adds subtle floral sweetness and rounds off the gas-dominant profile.
Total terpene content in the 1.5% to 3.0% range generally correlates with strong nose and flavor carry-through. Preservation depends on careful drying at 18 to 20 degrees Celsius with 55% to 60% relative humidity, then curing in airtight containers with minimal headspace. Excessive heat or airflow strips monoterpenes, dulling the top notes that define the gas character.
Experiential Effects and Use Patterns
All Gas OG Auto’s effects skew toward a heavy body load with a calm, steady mental state. Onset via inhalation typically begins within 2 to 10 minutes, with peak effects at 30 to 60 minutes and total duration of 2 to 4 hours. Users commonly cite muscle relaxation, a reduction in stress, and an easing into restfulness.
The influence of caryophyllene and myrcene likely accentuates the physical relaxation and perceived analgesia. Limonene’s presence adds a mild uplift that prevents the profile from feeling overly sedating at lower doses. At higher doses, couch-lock tendencies increase, which aligns with the indica-forward structure of the lineage.
Side effects mirror typical THC-dominant profiles, including dry mouth, red eyes, and short-term memory impairment at higher intake. Compared to racy sativa-dominant profiles, anxiety rates tend to be lower, especially when doses are modest and set-setting is controlled. Hydration and pacing are straightforward ways to moderate intensity and maintain comfort.
In social settings, many people reserve this cultivar for late afternoon or evening, pairing it with low-key activities and winding down. For productivity, microdosing inhalations can sometimes retain mental clarity while softening bodily tension. As always, personal tolerance is the main driver, so incremental dosing is advisable for dialing in the sweet spot.
Potential Medical Applications
While formal clinical data on specific named cultivars are limited, THC-dominant, OG-leaning autos like All Gas OG Auto are often selected anecdotally for pain, stress, and sleep. The combination of THC, myrcene, and beta-caryophyllene maps to user reports of muscle relaxation and body comfort. In patient surveys, high-THC flower frequently ranks well for sleep initiation, with many respondents noting easier onset of rest after evening use.
Beta-caryophyllene’s CB2 activity has been studied for potential anti-inflammatory signaling, which may contribute to perceived relief. Limonene’s association with positive mood in observational research could support stress reduction alongside the calming body profile. Together, these compounds form a plausible basis for symptom management in select scenarios.
For new medical users, low initial dosing is key—often starting with 1 to 2 inhalations or 2.5 milligrams oral THC-equivalent. Many report diminishing returns beyond moderate doses, where side effects can increase without proportional symptom benefit. Keeping a symptom journal for two weeks helps correlate dose and timing to outcomes.
As with all cannabis use, contraindications exist, especially for those sensitive to THC or with cardiovascular concerns. Consultation with a healthcare professional familiar with cannabinoid medicine is strongly recommended. Additionally, products should be sourced with verified lab results to confirm potency and screen for contaminants such as pesticides, heavy metals, and residual solvents.
Comprehensive Cultivation Guide
Cycle length and scheduling: Expect a seed-to-harvest window of about 70 to 85 days, with pistil initiation commonly around day 21 to day 30. Indoors, most growers run 18 hours of light and 6 hours of darkness from start to finish, though 20/4 can push vigor at the cost of slightly higher electricity. Outdoors, two to three successive auto runs per warm season are feasible in many climates.
Environment and VPD: Ideal daytime temperatures are 24 to 28 degrees Celsius in veg and 22 to 26 in bloom, with night temps 18 to 22. Relative humidity targets 60% to 70% in early veg, 50% to 60% in early flower, and 45% to 55% late. Vapor pressure deficit of 0.8 to 1.2 kilopascals in veg and 1.2 to 1.5 in bloom supports healthy transpiration and resin formation.
Light intensity and DLI: Aim for 400 to 600 PPFD in weeks one to two, 600 to 800 PPFD in weeks three to four, and 900 to 1,200 PPFD in bloom if CO2 is ambient. This equates to daily light integrals of roughly 30 to 50 mol per square meter per day under 18 hours. Keep an eye on leaf temperature; autos under excessive intensity can stunt rather than stretch.
Substrate and container: A 3 to 5 gallon (11 to 19 liter) container balances root volume and turnaround time for autos. Well-aerated media such as coco-perlite blends (70/30) or light, amended soils with 20% to 30% perlite encourage rapid rooting. Maintain soil pH around 6.2 to 6.6 or coco pH at 5.8 to 6.2 for optimal nutrient uptake.
Nutrition and EC: Provide a gentle but steady nutrient profile—EC 0.8 to 1.2 in early veg, 1.4 to 1.8 in peak bloom, and taper to 1.0 the final week. Nitrogen should be moderate; autos dislike heavy N late in the cycle. Supplement calcium and magnesium at 0.5 to 1.0 milliliters per liter if using RO water or coco-heavy mixes.
Irrigation strategy: Water to 10% to 20% runoff in coco to prevent salt buildup; in soil, water as needed to field capacity, allowing topsoil to dry slightly between events. Overwatering the first two weeks is a common error; seedlings prefer small, frequent volumes. By week three, plants can handle larger irrigations as roots fill the container.
Training and canopy management: Low-stress training from day 14 to day 24 can open the canopy and even out tops. Topping is optional and more risky in autos; if attempted, do it once between nodes three and four before day 20 to avoid stunting. Defoliation should be light and targeted, removing only leaves that block bud sites in weeks three to five.
Integrated pest management: Preventative measures reduce the likelihood of outbreak in the short auto window. Sticky traps, weekly scouting, and bio-inoculants such as Bacillus subtilis for foliar disease suppression are effective. Maintain cleanliness and positive room pressure, and quarantine new clones or plants to avoid hitchhiking pests.
CO2 and airflow: Ambient CO2 is adequate, but enrichment to 900 to 1,100 ppm in sealed rooms can support higher PPFD utilization. Good airflow requires one oscillating fan per 0.5 square meters of canopy and a refresh rate of at least one room volume per minute via exhaust. Slight negative pressure prevents odor leaks when paired with a carbon filter rated above actual CFM draw.
Flowering progression: By week three to four, button buds form and the aroma intensifies; watch for early calcium deficiency under high light. Weeks five to seven drive bulk, with potassium and phosphorus demand peaking. Late bloom weeks eight to ten are for ripening—avoid overfeeding and monitor trichomes for harvest timing.
Yield expectations: Indoor yields of 400 to 550 grams per square meter are attainable with high-quality LED lighting and optimized environment. Per-plant dry yields of 80 to 150 grams are common in 3 to 5 gallon pots. Outdoors, well-tended plants often produce 90 to 180 grams per plant, depending on sun hours and soil richness.
Harvest timing and ripeness: For a balanced effect, harvest when most trichomes are cloudy with 10% to 15% amber. For a heavier body effect, wait for 20% to 25% amber, accepting a slight terpene trade-off. Flush or taper feed the final 5 to 10 days depending on medium to improve burn quality.
Drying and curing: Dry at 16 to 20 degrees Celsius and 55% to 60% relative humidity for 7 to 14 days until small stems snap. Cure in airtight containers at 58% to 62% RH, burping daily for the first week, then every few days for another two to three weeks. Proper curing increases flavor intensity and smoothness while preserving terpenes.
Outdoor considerations: Plant after the last frost when night temps consistently exceed 10 degrees Celsius. Choose a location with 8+ hours of direct sun and good airflow to minimize fungal pressure. In wet regions, a simple overhead cover during late bloom can reduce the risk of botrytis in dense colas.
Genetic stability and breeding use: All Gas OG Auto’s consistent gas-forward bouquet and resin density make it a useful auto parent. Strain databases list crosses such as Dark Star Auto (Blim Burn Seeds) x All Gas OG Auto, reflecting its appeal in breeding programs. For home seed makers, open pollination in autos can widen variability; controlled selection over several generations improves uniformity.
