100 Og Strain: A Comprehensive Strain Guide

Overview and Naming

100 OG strain, sometimes listed on menus as 100 OG or One Hundred OG, sits within the West Coast OG Kush family that shaped modern cannabis. The name generally signals a high-potency, gas-forward OG selection bred or selected to deliver a quintessential OG experience. Dispensary listings describe it as a top-tier OG cut with heavy fuel aromatics, dense lime-to-forest green buds, and a potent relaxing finish. While breeder-of-record details are not standardized publicly, the strain’s reputation aligns closely with legacy OG phenotypes prized in California and beyond.

Because public breeder documentation is sparse for 100 OG, consumers often verify authenticity by comparing lab certificates of analysis and terpene fingerprints to known OG benchmarks. In practice, most 100 OG batches test in a THC-heavy profile with minor CBD and a dominant myrcene–limonene–caryophyllene terpene triad. In markets where OG variants are common, this strain competes with SFV OG, True OG, and Ghost OG for the classic gas-pine-citrus profile. The target strain for this guide is specifically 100 OG strain, as commonly referenced by retailers and enthusiasts.

History and Origins

OG Kush’s emergence in the mid-to-late 1990s, commonly traced from Florida to Los Angeles, set the template for countless OG phenotypes. Growers and patients gravitated to its fuel-citrus aroma and a potent blend of euphoria and physical relaxation. Over the 2000s and 2010s, cultivators stabilized and selected OG lines for distinct aroma ratios, plant structure, and yield improvements. 100 OG likely originates from this era of phenotype hunting where exceptionally potent and gassy cuts were named and circulated.

By the mid-2010s, dispensaries increasingly marketed OG-derived cuts with numeric or superlative branding, signaling strength or purity. 100 OG fits this branding logic, positioning itself as a pure or complete expression of OG character. Without a singular breeder record in the public domain, 100 OG is best seen as a named selection rather than a new cross. This tracks with the OG lineage’s culture of clone-only elites and regionally shared cuts.

Genetic Lineage and Breeding Notes

Although the exact cross for 100 OG is not standardized, most reports place it squarely within the OG Kush family. OG Kush itself is widely believed to descend from a Chemdog line crossed with a Kush or Hindu Kush influence, with notable variants like SFV OG contributing pine and gas emphasis. Many 100 OG expressions share the dense, golf-ball to conical OG bud structure, sharp gasoline aromatics, and a citrus-pine top note typical of OG Kush derivatives. Growers often describe internode spacing as medium, with a moderate stretch during the first three weeks of flower.

From a breeding standpoint, 100 OG’s desirable traits include a high calyx-to-leaf ratio, resin density suitable for extraction, and a dominant myrcene–limonene–caryophyllene terpene triad. Stabilizing the line would focus on preserving gas-forward volatiles while controlling OG’s susceptibility to powdery mildew and bud rot. Selections that maintain terpene totals above 2.0% by weight while delivering 20% to 28% THC are often prioritized in commercial phenohunts. As with many OG lines, the plant’s lateral branching and canopy density benefit from training to achieve uniform bud sites.

Appearance and Bud Structure

100 OG typically forms dense, medium-sized buds with a tight OG calyx stack, leaning popcorn to conical on lower branches and chunky colas up top. Colors range from lime to forest green, often with darker sugar leaves framing pale-green calyxes. Fiery orange pistils are common, and mature flowers appear heavily frosted due to abundant capitate-stalked trichomes. A calyx-to-leaf ratio around 65% to 75% is typical, making for efficient trimming compared with leafier hybrids.

Under strong lighting, the resin heads appear plentiful and bulbous, a favorable signal for solventless extraction. Buds often present a slightly fox-tailed edge when pushed with high PPFD or heat late in flower, a common OG behavior rather than a defect if kept minimal. The trim captures resin-rich sugar leaves that press well for rosin, contributing to extraction efficiency. When cured properly, the buds break apart with a tacky, resinous feel that lines grinders and fingers.

Aroma Profile

The aroma leans strongly gassy and chemmy, with top notes of diesel, lemon zest, and pine sap. Beneath the volatile front end, many batches carry earthy loam, wet stone, and faint pepper or clove. Freshly ground bud releases a wave of petrol and citrus, often described as an eye-watering fuel snap. Jar aroma intensifies significantly after 5 to 10 seconds of exposure as monoterpenes volatilize.

Terpene totals for OG cuts commonly land between 1.5% and 3.0% by weight in well-grown flower, and 100 OG falls in that window. Myrcene often contributes 0.5% to 1.2%, limonene 0.3% to 0.8%, and beta-caryophyllene 0.2% to 0.6%, though real-world values vary by grower and batch. Supporting terpenes like alpha-pinene and beta-pinene may combine for 0.1% to 0.3%, adding pine and a lucid sharpness. Trace ocimene, humulene, and linalool can show up at 0.03% to 0.15% each, nudging the aroma toward floral-spice complexity.

Flavor Profile

The inhale blends fuel and lemon, moving quickly to pine resin and a peppery finish characteristic of caryophyllene. On the exhale, expect a lingering diesel note with a citrus pith bitterness that many OG fans prize. Vaporizing at lower temperatures, such as 175 to 190 C, emphasizes lemon-pine brightness and reduces throat bite. Combustion shifts the balance toward earth and pepper as delicate monoterpenes volatilize rapidly.

Cure quality heavily impacts the flavor, with 10 to 14 days of controlled drying and a 4 to 8 week cure ideal for depth. Over-drying below 55% relative humidity tends to mute lemon and pine, leaving a flatter earthy profile. In solventless rosin, 100 OG skewing to limonene and pinene expresses a crisp pine-citrus leading edge with a gassy mid-palate. Hydrocarbon extracts often preserve a louder fuel top note, but both formats can deliver a quintessential OG taste when well-executed.

Cannabinoid Profile and Potency

Most 100 OG batches fall into a high-THC, low-CBD profile, aligning with OG family norms. Reported lab results for OG-type cultivars commonly show THCa in the 20% to 28% range, with occasional elite batches exceeding 30% THCa in optimized conditions. After decarboxylation, this translates to roughly 18% to 26% total THC by weight depending on moisture content and conversion efficiency. Minor cannabinoids like CBG often register between 0.2% and 1.0%, with CBD typically under 0.5%.

Against legal market baselines, 100 OG’s potency sits above average. Many state datasets show median flower THC around the high teens to low 20s percent, while premium OG batches skew higher. Inhaled dosing of 5 to 10 mg of THC can noticeably affect newer consumers, whereas experienced users often consume 15 to 30 mg equivalents across sessions. Because of its rapid onset and density of psychoactivity, titration and mindful pacing are recommended, especially with concentrates derived from 100 OG.

Terpene Profile and Minor Aromatics

Dominant terpenes generally follow a myrcene–limonene–beta-caryophyllene stack, sometimes joined by alpha-pinene as a co-dominant. This distribution yields the classic fuel-citrus-pine nose with an earthy backbone and peppery exhale. In robust expressions, total terpenes cluster around 2.0% to 2.8%, which many users perceive as an aromatic sweet spot without harshness. Below 1.5%, the nose and flavor can seem subdued, especially after several weeks of jar time.

Myrcene contributes musky earth and may enhance subjective relaxation as part of the entourage effect. Limonene elevates citrus brightness and is often associated with mood-lift in user reports. Beta-caryophyllene engages CB2 receptors, a point of interest for inflammation pathways in preclinical research. Pinene variants sharpen the top end with coniferous clarity and may moderate sedative feel at low doses.

Experiential Effects and Onset

Inhaled 100 OG typically hits within 1 to 5 minutes, with a fast wave of head pressure and a brightening mood in the early minutes. A warm body melt follows, concentrating behind the eyes, neck, and shoulders. Peak intensity arrives at 30 to 60 minutes, with a taper over 2 to 3 hours for most users. Lower doses lean uplifting and functional; higher doses trend sedative with heavier eyelids.

Subjectively, many users describe 100 OG as balanced within the OG spectrum: clear and euphoric upfront, then calm and physically grounding. At moderate intake, it pairs with reflective tasks, music, or passive entertainment rather than fine-detail work. At larger doses, couchlock becomes more probable, particularly late in the day. Edibles or potent rosin derived from 100 OG can extend the experience to 4 to 6 hours, with a slower onset and deeper body involvement.

Tolerance, Side Effects, and Set-and-Setting

Common side effects include cottonmouth and dry eyes, reported by a significant portion of users across high-THC strains. Transient anxiety can occur in sensitive individuals, especially at higher doses or in stimulating environments. A mild increase in heart rate is typical with THC, often in the range of 10 to 30 beats per minute shortly after inhalation. Hydration, paced dosing, and a comfortable setting reduce the likelihood of unpleasant effects.

Tolerance builds with frequent use as CB1 receptor signaling adapts, often noticeable after several days of consecutive sessions. Taking 48 to 72 hour breaks can reset responsiveness for many users. Avoid combining with alcohol, which can unpredictably intensify sedation and impair coordination. For new consumers, starting with 1 to 2 inhalations, pausing 10 minutes, and reassessing is a practical harm reduction approach.

Potential Medical Applications

Patients commonly reach for OG-type strains for stress relief, muscle tension, and sleep support. THC possesses analgesic and antispasmodic properties in clinical and preclinical literature, while beta-caryophyllene’s CB2 activity is under investigation for inflammation modulation. Myrcene often correlates with subjective sedation in user surveys, and limonene is studied for mood-related pathways. Together, these may create a profile compatible with evening use and muscle relief for some individuals.

Potential use cases include moderate nociceptive pain, situational anxiety, and appetite stimulation, though responses vary widely. For inhaled use, medical patients often start at 1 to 2 inhalations and titrate, aiming for symptom relief with minimal cognitive disruption. For oral formats made from 100 OG, 2.5 to 5 mg THC is a conservative starting point, with gradual 1 to 2.5 mg increases as needed. Always consult a medical professional for personalized guidance, and consider terpene preferences when choosing batches.

Cultivation Guide: Genetics and Sourcing

Because the public breeder record for 100 OG is limited, sourcing verified clones from reputable nurseries or cultivators is the most reliable route. If starting from seeds marketed as 100 OG, expect phenotype variation and plan a selection process across 6 to 10 plants at minimum. Look for hallmark OG traits: fuel-forward aroma in late veg rub tests, medium internode spacing, and strong lateral branching with dense, resinous flowers. Keep detailed notes on terpene intensity by week 6 of flower to inform your keeper selection.

Ask suppliers for prior lab data including THCa, total cannabinoids, and a terpene breakdown to confirm OG-typical fingerprints. Authentic OG-leaning phenos will usually spike myrcene and limonene with caryophyllene in a strong supporting role. If possible, evaluate small test runs for disease resistance, as OGs may be susceptible to powdery mildew. Choosing a cut with good airflow and calyx density can significantly improve commercial viability.

Cultivation: Environment and Media

OG family plants like 100 OG perform best in stable, slightly cool rooms with strong airflow. Day temperatures of 22 to 27 C (72 to 80 F) and nights of 18 to 21 C (64 to 70 F) are a good baseline. Relative humidity targets of 60% to 70% in veg and 45% to 55% in flower help balance vigor and mold prevention. A gentle VPD ramp from 0.9 to 1.3 kPa keeps transpiration in range without stressing the canopy.

In soil or soilless mixes, a pH of 6.2 to 6.7 is ideal; in hydro or coco drip systems, 5.8 to 6.2 works well. Veg under 400 to 600 PPFD and flower at 800 to 1000 PPFD to avoid foxtailing and terpene burn, increasing only if CO2 is enriched. With 1000 to 1200 ppm CO2, some growers push 1100 to 1200 PPFD, but watch for heat and nutrient uptake limits. Maintain strong, laminar airflow across and through the canopy with 0.3 to 0.5 m/s of leaf-surface airspeed.

Cultivation: Training and Canopy Management

100 OG stretches about 1.5x to 2.0x in the first two to three weeks of 12/12, aligning with many OG Kush expressions. Top once or twice in late veg and apply low-stress training to create a flat, even canopy. A single-layer SCROG or trellis net helps support heavy colas and improves light penetration. Defoliate lightly at day 21 and day 42 of flower to open airflow while preserving photosynthetic capacity.

Plant density depends on container size and veg time. A common indoor layout is 4 to 6 plants per square meter in 10 to 15 liter pots with a 3 to 4 week veg. For SOG, run more plants in smaller containers with minimal veg and a single main cola structure. Keep canopy depth to 30 to 45 cm so lower buds remain dense and marketable.

Cultivation: Nutrition and Irrigation

OGs prefer steady calcium and magnesium availability, especially in coco and high-intensity lighting. In veg, target an EC of 1.4 to 1.8 mS/cm, rising to 1.8 to 2.2 mS/cm in mid flower depending on cultivar response. Aim for a nitrogen-forward ratio in veg, then shift to phosphorus and potassium emphasis after week 3 of flower. Excessive nitrogen late in flower can mute terpenes and slow ripening.

Irrigate to 10% to 20% runoff in salt-based systems to avoid salt buildup, and let the medium dry back appropriately between feeds. In coco, daily or multi-daily fertigation with controlled drybacks can improve consistency and yield. Monitor runoff pH and EC weekly; keep soil pH near 6.5 and coco around 5.9 to 6.1 for optimal nutrient uptake. Organic growers can succeed with high-quality compost, aeration amendments, and top-dressing, though yield may trail salt-based approaches by 5% to 15% unless dialed in.

Cultivation: Pests, Disease, and IPM

Dense OG flowers are particularly sensitive to powdery mildew and botrytis if humidity and airflow slip. Implement an IPM program from day one: preventive biologicals, sticky cards for monitoring, and regular canopy inspections. Predatory mites such as Amblyseius swirskii and Neoseiulus californicus help manage thrips and mites, while Bacillus subtilis and Bacillus amyloliquefaciens products support foliar health. Avoid sulfur or heavy oils once flowers set; if used, apply only in veg and allow adequate time before flowering.

Keep leaf surfaces dry with adequate spacing and oscillating fans. Prune interior foliage to break up microclimates where humidity can spike above 60% late in flower. Sanitize tools and quarantine new clones to prevent introducing pests like russet mites. If PM appears, remove affected leaves promptly, improve environment, and consider biological fungicides compatible with late flower only if compliant with local regulations.

Cultivation: Flowering, Ripening, and Harvest Timing

100 OG typically flowers in 8 to 9 weeks indoors, though some phenos may prefer 63 to 70 days for full flavor expression. Expect pistil recession and a strong fuel aroma surge in the final two weeks. Under optimal conditions, indoor yields o
