All Gas, often sold as All Gas OG and formerly circulated as Asphalt Plant, is a heavy, fuel-forward cultivar prized for dense, resin-rich flowers and a profoundly relaxing effect profile. The strain sits in the indica-leaning camp, with most cut reports indicating a 70/30 indica-to-sativa expression. In consumer markets from California to Oregon, lab certificates of analysis (COAs) commonly show THC between 19% and 24%, with outliers touching 26% in top-shelf indoor lots. Total terpene content typically falls between 1.5% and 3.0% by weight, a range associated with loud aroma and persistent flavor. That combination of potency and terpene saturation explains why the All Gas strain has become a fixture in “gas” lovers’ rotations.
Despite its modern popularity, All Gas throws back to classic West Coast diesel and OG Kush sensibilities. The bouquet emphasizes volatile hydrocarbon notes reminiscent of diesel fuel, warmed rubber, and skunk, layered over pine and earthy undertones. The effects generally arrive as a quick, chest-warming body melt with a calmer, mood-lifting headspace. For many, it is an evening driver—something to cap the day, enhance appetite, and smooth out aches. Growers appreciate its vigorous vegetative growth, strong lateral branching, and yield potential that can double that of lighter-yielding OG cuts under identical conditions.
In the retail landscape, All Gas is frequently positioned as a robust option for consumers seeking a classic “couch-friendly” experience without sacrificing flavor. It has proven adaptable to both indoor and outdoor programs, with fast flowering times that appeal to commercial operators. The cultivar’s popularity is reinforced by visual appeal—thick colas, purple-tipped sugar leaves in cooler finishes, and heavy trichome coverage that shimmers under shop lights. These traits have made it a staple in pre-rolls, live resin, and cured-budder concentrates where diesel-forward profiles command premium shelf space. As a brand-agnostic genetic, it appears in both craft and scaled operations, maintaining distinctiveness through its unmistakable gas aroma.
The context for this guide is the “all gas strain,” reflecting what consumers search when they want the loud, high-octane phenotype associated with diesel and OG families. The following sections examine its history, lineage, appearance, and sensory data with an emphasis on statistics and cultivation specifics. Growers will find actionable strategies for dialing in canopy management, while patients can evaluate whether All Gas aligns with their therapeutic goals. By the end, you should have a comprehensive, data-backed understanding of why this strain has become a go-to for gas aficionados. And critically, you will learn how to identify and cultivate the most compelling expressions of All Gas in diverse environments.
History And Naming: From Asphalt Plant To All Gas
All Gas is widely attributed to Humboldt Seed Company (HSC), which popularized the cultivar under the name All Gas OG after it initially circulated as Asphalt Plant. The renaming was more than cosmetic; it captured the seed’s defining characteristic—an aggressively petrol-forward nose—while aligning with retail-friendly nomenclature. HSC is known for large-scale phenotype hunts in Northern California, sometimes exceeding 10,000 plants, and selection work from those hunts helped sharpen All Gas’s market-ready expression. By late 2019 into 2020, the All Gas OG name had gained traction with licensed growers and dispensaries across the West Coast. That period coincided with the broader consumer swing back toward classic fuel and skunk profiles after a multi-year dessert-terp moment.
The shift from Asphalt Plant to All Gas OG also reflects a marketing reality: diesel-forward strains can be polarizing, but when they hit, they cultivate loyalty. Retail data from multiple legal states consistently shows that gassy cultivars maintain above-average repurchase rates relative to fruit-forward varieties, often by 10% to 20% in store-level SKU analyses. All Gas tapped that demand by offering a balanced package of yield, bag appeal, and potency. It also dovetailed with the resurgence of OG Kush and Chem/Diesel derivative lines on menus, enabling cross-merchandising with other heavy hitters. For concentrates makers, the name instantly communicates flavor expectations to solvent and solventless consumers alike.
Although the exact year of its first release can vary by source, the late 2010s marked its broader commercial emergence. Early-adopting cultivators cited relatively uniform growth patterns, a fast 8- to 9-week bloom, and terpenes that survived aggressive post-harvest handling. Those traits helped it transition from a breeder-highlighted selection into a reliable production cultivar. As test batches moved through the supply chain, feedback loops from extraction labs and dispensary buyers further reinforced the focus on high-odor, high-resin phenotypes. The result is a cultivar that feels modern but reads classic in aroma and effect.
Genetic Lineage And Breeding Context
The lineage most commonly reported for All Gas OG is Humboldt OG crossed with Humboldt Venom OG, yielding an indica-leaning hybrid with pronounced fuel notes. Humboldt OG itself is an OG Kush family expression known for dense structure and earthy-pine fuel aromatics. Humboldt Venom OG descends from Venom OG lineages, adding a skunky, resinous edge and body-heavy effects. Together, these parents stack OG traits—fuel, pine, earthy spice—with extra hydrocarbon punch and yield. That combination matches what growers and testers report: a terpene mix dominated by myrcene and caryophyllene with an OG-like limonene and pinene assist.
Breeding logic for this cross leans on complementary heritable features. OG-dominant architecture tends toward stout, internode-dense plants that thrive with topping and support. Venom-leaning lines often add cuticle thickness, resin gland density, and heavier calyx build, which can enhance trichome production per unit of bud mass. In practice, many All Gas phenotypes show a calyx-forward structure with high bud density and minimal foxtailing when VPD is controlled. This supports both cured-flower marketability and extract yields that can exceed 15% for hydrocarbon extraction on well-grown batches.
Phenotypic variation in All Gas is narrower than some polyhybrids, but selection still matters. Growers consistently report two notable phenos: a darker-leaf, shorter plant with ultra-dense nugs and maximum fuel intensity, and a slightly taller variant with stronger pine-citrus top notes and marginally higher yields. The latter may finish 3 to 5 days later but rewards with larger colas and easier trimming due to a favorable calyx-to-leaf ratio. Across both, breeders emphasize the importance of environment in terp expression—cooler nighttime temps in late bloom intensify the diesel-rubber character while encouraging purple anthocyanin expression. Careful selection from 5 to 10 seeds can reliably produce a keeper that meets the All Gas brief.
While mislabeling can happen in markets with multiple “gas” cultivars, All Gas’s comparatively fast finish and distinctive asphalt-and-pine nose help distinguish it. Genetic testing panels that scan SNP markers for OG family signatures often cluster All Gas near OG-influenced groups. That result aligns with grower observations and sensory notes, reinforcing the reported parentage. In short, from both an organoleptic and agronomic standpoint, All Gas behaves like a modern OG derivative dialed for yield and resin.
Appearance And Bag Appeal
All Gas presents with medium to large spear-shaped colas that stack tightly along topped mains and secondary branches. Buds are typically olive to forest green with purple to plum accents at the sugar leaf tips, especially when night temperatures dip below 60°F (15.5°C) in late bloom. Pistils mature from deep orange to burnt copper, creating high contrast against heavy trichome frosting. Under magnification, capitate-stalked trichomes are plentiful and long-stalked, often creating a greasy, resin-glass look. This is the kind of flower that gums up scissors quickly during trimming.
The calyx-to-leaf ratio leans favorable, making hand-trimming efficient and machine-trimming less damaging than with leafier OGs. Dried buds cure into compact, rock-hard nuggets that retain shape in jars and resist crumble when properly humidified at 58% to 62% RH. Bud density is high, which increases bag appeal but necessitates attentive airflow during late flower to avoid botrytis in humid climates. Expect minimal foxtailing in well-managed environments with stable PPFD and VPD. In retail displays, the combination of deep greens, purples, and thick frost signals potency to consumers.
Weight retention through drying and curing is solid due to resin density and calyx mass. Typical dry-back from harvest to saleable flower sits around 75% to 80% moisture loss, yielding 20% to 25% final weight, aligning with industry norms. Trim yields are moderate, and sugar trim is notably resinous, making it useful for hash or infused prerolls. The overall aesthetic is quintessential “gas”—compact, dark-hued flowers that telegraph intensity. That visual identity helps the strain stand out even before a jar is opened.
Aroma: The High-Octane Nose
True to its name, All Gas delivers a layered, assertive bouquet that experienced consumers identify instantly. The dominant notes evoke diesel fuel, hot asphalt after summer rain, and a whiff of warmed rubber. Beneath that, pine resin, black pepper, and damp forest floor provide grounding earthiness. Subtle citrus pith—more grapefruit rind than sweet orange—often flickers at the edge. When ground, the aroma intensifies toward skunk and petrol with a faint minty backend in some cuts.
Lab-terp data from West Coast COAs frequently places total terpenes between 1.5% and 3.0% w/w, a band correlated with strong jar appeal and persistent aroma post-grind. Myrcene typically leads in the 0.6% to 1.2% range, followed by beta-caryophyllene at 0.3% to 0.8%, and limonene at 0.2% to 0.5%. Secondary contributors such as humulene (0.1% to 0.3%), linalool (0.05% to 0.2%), and alpha-pinene (0.05% to 0.2%) round out the profile. This terp stack is classic for OG-descended cultivars, but All Gas pushes the hydrocarbon and skunk aspects further. That makes it a frequent top-5 jar test for shoppers who prioritize smell-first buying.
Environmental factors can swing aromatic emphasis meaningfully. Cooler late-bloom temps tend to preserve volatile monoterpenes and encourage a sharper diesel tone. Conversely, warmer, drier rooms can drift the bouquet toward peppery earth and away from bright pine-citrus. Proper cure at 60°F/60% RH for 10 to 14 days helps retain the high notes while mellowing any acrid edges. When dialed in, the aroma lingers on grinders, hands, and rooms more than average—hence the name.
Flavor And Combustion Characteristics
On inhalation, All Gas is bold and immediate—expect diesel and kerosene-like notes upfront with pine resin and pepper down the middle. The finish skews Kushy with earthy undertones and a faint grapefruit bitterness that keeps the profile from feeling flat. Vaporization at lower temperatures (338°F to 356°F / 170°C to 180°C) highlights pine-limonene brightness and soft florals from linalool. Combustion in joints or bowls introduces a heavier, smoky character reminiscent of charred cedar and black pepper. The aftertaste clings as a savory, resinous coating that persists through multiple tokes.
Well-grown flower produces expansive yet smooth smoke, particularly after a slow cure and proper burping to off-gas chlorophyll volatiles. White to light-gray ash is common when nutrient regimens are balanced and plants are adequately flushed or fed cleanly near harvest. Overfeeding late bloom can dull flavor and introduce harshness, so a taper over the last 10 to 14 days is recommended. In concentrates, the flavor intensifies toward tarry diesel with vivid pine and pepper. Hydrocarbon extracts typically capture the “gas” most vividly, while rosin leans earthier with pleasant Kush spice.
For edible and infusion applications, All Gas imparts a savory-herbal backbone that pairs well with chocolate, coffee, and toasted nut profiles. Terp retention in decarboxylated products is limited, but caryophyllene and humulene-derived spice notes can persist. In cartridges, terpene reintroduction is often used to maintain the signature gas, targeting a balanced ratio of myrcene, caryophyllene, limonene, and a touch of alpha-pinene. Consumers who prefer clean, pine-diesel pulls will find All Gas delivers consistent flavor across formats. That multi-format fidelity is part of its commercial success.
Cannabinoid Composition And Potency Metrics
COAs for the All Gas strain frequently report THC in the 19% to 24% range for cured flower, with top-performing indoor batches reaching 25% to 26%. CBD content is typically minimal, falling below 0.5%, often around 0.1% to 0.3%. Minor cannabinoids like CBG register in the 0.3% to 1.2% range, while trace levels of THCV and CBC are sporadically detected. Total cannabinoids often sum to 20% to 28%, consistent with premium indoor hybrids. For extract products, total cannabinoids commonly exceed 70% to 80% in distillate and 60% to 75% in live resins, depending on process and cut.
Potency is only half the story; terpene load shapes perceived strength and onset. Research and industry sensory data suggest that higher terpene content, particularly myrcene and limonene, can modulate absorption and subjective intensity. With total terpenes around 2% to 3%, All Gas often feels stronger than the THC number alone implies. Many users report a rapid onset within 5 to 10 minutes for inhalation, a peak at 45 to 90 minutes, and a tail that can last 2 to 4 hours. Edible onset and duration follow typical oral kinetics—60 to 120 minutes to onset and 4 to 8 hours of effect.
Batch-to-batch variability exists, but All Gas shows tighter potency clustering than dessert hybrids known for wider swings. Indoor runs with consistent PPFD, CO2, and feeding produce predictable cannabinoid totals. Outdoor sun-grown can match indoor THC on warm, dry seasons but may show slightly lower terp totals if harvest management is rushed. Post-harvest handling is critical; excessive heat and oxygen can oxidize THC to CBN and burn off monoterpenes. Best practice storage maintains potency within a few percentage points for several months.
Terpene Profile: Dominance, Ratios, And Sensory Impact
All Gas’s terpene fingerprint is led by beta-myrcene, beta-caryophyllene, and limonene, with humulene, linalool, and alpha-pinene as secondary players. A representative ratio from COA summaries might read myrcene 1.0%, caryophyllene 0.6%, limonene 0.4%, humulene 0.2%, linalool 0.1%, and alpha-pinene 0.1% for a 2.4% total. This pattern supports the diesel-pine-pepper trifecta that defines its sensory identity. Myrcene contributes musky earth and relaxation, caryophyllene adds peppery spice and potential CB2 receptor activity, and limonene brings citrus brightness and mood lift. Humulene layers woody bitterness, while linalool and pinene contribute floral and pine, respectively.
Terpene expression is strongly environment-dependent. Cooler finishing temperatures and careful curing can retain monoterpenes, preserving the top-end punch that consumers identify as “gas.” Over-drying below 55% RH or curing above 68°F (20°C) can flatten the profile, shifting emphasis to heavier sesquiterpenes and muting the high notes. Growers aiming for a maximal diesel pop often target a 60/60 dry room—60°F and 60% RH—for 10 to 14 days, with gentle air exchange. Burping sealed containers during early cure helps equalize moisture and off-gas chlorophyll-related volatiles.
In extraction, terp fractionation reveals the dominance of myrcene and caryophyllene in this strain. Hydrocarbon extraction preserves more of the monoterpenes than high-heat processes, re
