History and Breeding Background

After 8 OG is a modern OG-family cultivar developed by Sumo Seeds, a European breeder known for stabilizing flavor-forward lines and resilient indica-dominant hybrids. The name nods to late-evening enjoyment and, for many, evokes the classic mint-chocolate confection that people often reach for after dinner. Sumo Seeds positions this strain as mostly indica in heritage, aligning it with the relaxing, end-of-day character many consumers expect from the OG umbrella.

While legacy OGs trace back to the 1990s in Southern California, Sumo Seeds brought a European refinement to the profile, selecting for stronger structure and repeatable chemotypes. The breeding focus with After 8 OG appears to balance a deeply soothing body effect with a clean, terpene-dense nose. This dual objective fits a broader market trend documented by European seedbanks during the 2015 to 2022 period, where demand for indica-leaning, aromatic OG variants increased steadily.

Specific parent lines have not been publicly disclosed by the breeder, which is common with commercial OG crosses to protect intellectual property. However, consumer and grower reports consistently highlight a classic OG backbone with a contemporary flavor twist. This suggests the use of a terpene-rich OG progenitor paired to a stabilizing indica donor, maintaining potency while reinforcing structural uniformity.

Sumo Seeds has a history of developing lines with manageable flowering times and robust resin production, and After 8 OG follows that playbook. The cultivar tends to finish faster than many haze-dominant hybrids yet maintains high trichome density associated with OG genetics. These traits align with market data showing indica-dominant hybrids remain top sellers in many European and North American dispensaries due to their potency-to-cycle-length ratio.

In the broader historical arc of the OG family, After 8 OG represents the move from regional legend to globally standardized offerings. Early OGs varied widely between cuts, but modern seedlines aim for repeatability and distinct sensory signatures. By prioritizing an evening-friendly experience and a nuanced aroma, Sumo Seeds has crafted a strain that fits both connoisseur and practical cultivation needs.

Genetic Lineage and Indica Dominance

Sumo Seeds identifies After 8 OG as mostly indica in its heritage, and that classification aligns with how the plant grows and how users describe its effects. Indica dominance in contemporary OG descendants typically implies a structure with tighter internodes, faster finish times, and a heavier body effect. Field observations of OG-leaning indica hybrids often show flowering windows around 56 to 63 days, and After 8 OG generally falls in that 8 to 9 week band.

Publicly, exact parents are not listed, which is increasingly common as breeders guard high-performing genetics. Based on morphology, the line behaves like an OG-forward cross supported by an Afghan-leaning or Kushy indica donor. This sort of pairing tends to enhance resin production and improve stem strength without diluting the recognizable pine-fuel-citrus profile OG fans expect.

OG lines as a group are believed to descend from a Chemdawg and Kush-related framework, sometimes with Lemon Thai influence. Those backgrounds routinely produce terpene stacks dominated by myrcene, limonene, and beta-caryophyllene. After 8 OG aligns closely with that triangle, though many growers note cooler herbal facets that skew toward mint or eucalyptus in certain phenotypes.

In practical terms, indica dominance correlates with denser bud formation and a stronger need for dehumidification late in flower. The structure is often moderately squat but can still show notable stretch during the first two weeks of 12 or 13 hours of darkness. In side-by-side rooms, indica-leaning OG phenotypes commonly stretch 1.5 to 2.0 times their vegetative height, making predictive canopy management an important part of the grow.

Appearance and Bud Structure

After 8 OG typically presents medium-sized, conical flowers that are heavily resin encrusted. Calyxes stack into tight clusters, producing compact colas with minimal leaf-to-calyx ratio when dialed-in. Expect a deep forest to lime green coloration, accented by orange to rust pistils that turn darker as the cure progresses.

Under strong LED lighting at 800 to 1000 micromoles per square meter per second PPFD, trichome coverage is pronounced and sticky to the touch. The flowers often show a subtle OG fox-tail at the tips in hotter rooms, though stable canopy temperature control minimizes this. Sugar leaves remain small and dusted, which simplifies post-harvest trimming.

In cross-section, buds are dense but not rock-hard, maintaining a cushion-like give that speaks to healthy moisture management during development. Mature trichomes turn cloudy across most of the canopy around weeks 8 to 9, with amber percentages increasing by 7 to 10 days thereafter. The final bag appeal is high, with a glossy resin sheen that persists after the cure if humidity is kept stable.

Growers should note that branch structure, while sturdier than classic viney OG cuts, still benefits from trellising. Colas can gain significant mass in the last 10 to 14 days, and lateral branches may lean without support. A single layer of netting at 20 to 30 centimeters above the canopy is generally sufficient for indoor setups.

Aroma and Terpene-Driven Nose

Aromatically, After 8 OG leans on the iconic OG triad of pine, fuel, and citrus, complemented by cool herbal notes. Many growers and consumers report a refreshing mint or eucalyptus undertone, which pairs nicely with the limonene-driven high citrus zest. On the break, the bouquet broadens to include cracked black pepper and faint earthy sweetness.

Freshly ground flower is noticeably sharper than whole buds, releasing top notes that can fill a room quickly. In controlled sensory sessions, users commonly describe the nose as clean, crisp, and slightly sweet, rather than solely gassy. This is indicative of a terpene distribution where myrcene and limonene are balanced by beta-caryophyllene and pinene.

During late flower, the room aroma intensifies, and carbon filtration becomes important to maintain odor control. Activated carbon filters typically reduce volatile organic compound emissions by 90 percent or more when properly sized to the room’s cubic feet per minute airflow. For small home grows, a 4-inch carbon filter paired with a 200 CFM fan is usually adequate for one light, while 6-inch 400 CFM systems are better for multi-light tents.

Flavor and Smoke or Vapor Quality

On the palate, After 8 OG delivers an OG-forward base of pine resin and diesel with a bright citrus peel highlight. Where phenotypes skew minty, the finish can feel cooling and clean, reminiscent of peppermint tea or menthol without harshness. A light earthy cocoa nuance sometimes appears after a slow cure, adding depth to the overall flavor arc.

Combustion yields a smooth inhale when dried and cured at 60 percent relative humidity and approximately 18 to 20 degrees Celsius. Vaporization between 175 and 195 degrees Celsius preserves terpene complexity and reduces throat bite. Many users note that the mint-pepper combination expands more in vapor than smoke, likely due to the lower degradation of monoterpenes.

Flavor holds over multiple pulls when buds are cured in 58 to 62 percent humidity packs for at least 21 to 30 days. Quick-dried samples lose the delicate herbal edge and skew toward a generic diesel profile. Proper post-harvest handling is therefore key to expressing the cultivar’s full flavor signature.

Cannabinoid Profile and Potency Data

As a mostly indica OG descendant, After 8 OG is typically high in THC with minimal CBD. Across comparable OG-dominant lines, lab-tested THC values commonly range from 18 to 24 percent by dry weight, with optimized phenotypes occasionally surpassing 25 percent. CBD often sits below 1 percent, while CBG totals in the 0.3 to 1.0 percent range are not unusual for resin-rich OG lines.

Total terpene content in OG-leaning cultivars frequently measures between 1.5 and 3.0 percent, which correlates with the assertive aroma and flavor many report. Potency is strongly influenced by cultivation variables, including light intensity, spectrum, and nutrient balance. In controlled environments, raising PPFD from 600 to 900 micromoles per square meter per second under sufficient CO2 can increase cannabinoid yield per square meter by 10 to 20 percent, provided irrigation and nutrition are adjusted appropriately.

It is important to emphasize that cannabinoid outcomes are phenotype dependent. Even within a single seed pack, a spread of 3 to 6 percentage points in THC is common due to genetic variance and microclimate differences. Targeting uniform environmental parameters and selecting high-performing mothers can narrow that spread in subsequent runs.

For patients and consumers, the high-THC, low-CBD architecture translates to a fast-onset, potent experience that can be sedative at moderate doses. Minor cannabinoids such as THCV, CBC, and CBN usually appear in trace amounts, often below 0.2 to 0.5 percent in flower. Extended curing and storage conditions may increase measurable CBN slightly due to THC oxidation, as shown in stability studies of stored cannabis material.

Terpene Profile and Chemical Drivers

Available reports and typical OG chemistry suggest myrcene, limonene, and beta-caryophyllene anchor After 8 OG’s terpene profile. Common ranges in OG-heavy cultivars place myrcene around 0.3 to 0.8 percent, limonene around 0.2 to 0.6 percent, and beta-caryophyllene around 0.2 to 0.5 percent by dry weight. Secondary contributors often include alpha-pinene, humulene, and linalool in the 0.05 to 0.2 percent band.

The mint or eucalyptus impression some users detect can be explained by the interplay of alpha-pinene and eucalyptol in trace amounts, even if eucalyptol is present below 0.05 percent. Menthol-like coolness is also a perceptual effect when terpenes such as pinene and limonene are balanced by peppery caryophyllene. This kind of matrix effect is well-documented in aroma chemistry, where small proportion changes alter sensory outcomes significantly.

Total terpene content around 2.0 percent often produces a strong room-filling aroma and a persistent aftertaste. In addition to flavor, these terpenes have documented pharmacological properties. Beta-caryophyllene is a CB2 receptor agonist, myrcene is associated with sedative and analgesic potential in preclinical models, and limonene has been studied for mood-elevating and anxiolytic effects in animal and limited human contexts.

Growers who aim to maximize terpene expression should focus on moderate temperatures, adequate potassium and sulfur in late flower, and gentle drying practices. High heat and excessive UV can volatilize monoterpenes and dull the bouquet. Post-harvest, maintaining 60 to 62 percent relative humidity preserves monoterpenes significantly better than low humidity curing regimens.

Experiential Effects and Onset

After 8 OG’s effect profile is consistent with a mostly indica OG: a fast-onset head change that settles into a calm, body-centered relaxation. Users often report a warm physical release within 10 to 20 minutes after inhalation, accompanied by a clear but mellow euphoria. The overall arc suits evening use or low-stimulation environments due to its tranquil finish.

Onset timing depends on route of administration. With inhalation, initial effects can start within 2 to 5 minutes and peak around 30 to 60 minutes, lasting 2 to 4 hours. Edible preparations extend onset to 30 to 90 minutes and can last 4 to 8 hours or more, with a heavier body load typical of high-THC, low-CBD strains.

Common positive notes include muscle relaxation, stress relief, and a steadying of racing thoughts. Some individuals also note a gentle uplift that avoids the jitteriness associated with certain sativa-dominant profiles. At higher doses, couchlock becomes more likely, and short-term memory interference can increase, which is characteristic of potent OG-leaning chemotypes.

Adverse effects are generally the familiar cannabis side effects: dry mouth, dry eyes, and transient tachycardia. Cannabis can raise heart rate by 20 to 50 beats per minute in susceptible individuals shortly after consumption, so those with cardiovascular concerns should start low and go slow. Hydration, paced dosing, and comfortable surroundings mitigate most minor negatives for typical users.

Potential Medical Applications and Considerations

The indica-forward, OG-style chemical profile of After 8 OG points to potential utility for pain, muscle tension, and sleep-related issues. Myrcene’s sedative reputation, combined with beta-caryophyllene’s CB2 activity, offers a rationale for analgesic and anti-inflammatory support in certain users. Many patients also report improved sleep onset and fewer nighttime awakenings when using indica-leaning OG cultivars in the evening.

For mood and stress, limonene and linalool can contribute to perceived calm and uplift. While randomized clinical evidence specific to this strain is not available, broader cannabis literature supports anxiolytic and antidepressant potential in some contexts. Patients with anxiety should still monitor dose size, as high-THC chemotypes can exacerbate symptoms in a subset of individuals.

Appetite stimulation is a common effect in OG-heavy lines, which may aid those dealing with decreased appetite. For neuropathic discomfort, the combination of THC, myrcene, and caryophyllene is frequently cited by patients in observational surveys. However, individual responses vary widely and should be mapped through careful titration.

Medical users should prioritize lab-tested products to confirm potency and the absence of contaminants such as pesticides, heavy metals, and mold. Start with low doses, particularly for naive users or those sensitive to THC. Keeping a simple symptom and dose log over 7 to 14 days often reveals the most effective and best-tolerated regimen.

Comprehensive Cultivation Guide: From Seed to Cure

Breeder and growth type: After 8 OG was bred by Sumo Seeds and is mostly indica in heritage. Growers can expect a manageable flowering period of approximately 8 to 9 weeks under 12 hours of darkness. The plant structure combines OG resin production with improved lateral strength, though light trellising is still recommended for heavier colas.

Environment and climate: In vegetative growth, target 24 to 28 degrees Celsius with 60 to 70 percent relative humidity and a vapor pressure deficit of around 0.8 to 1.1 kilopascals. In flower, reduce to 20 to 26 degrees Celsius with 45 to 55 percent relative humidity, stepping down to 40 to 45 percent in the final 2 weeks to reduce botrytis risk. Aim for gentle airflow of 10 to 15 complete room air exchanges per hour in tents and employ oscillating fans for uniform canopy movement.

Lighting and PPFD: For seedlings and early veg, 200 to 400 micromoles per square meter per second supports tight internodes. In late veg, raise to 400 to 600 micromoles per square meter per second, and in flower, 700 to 1000 micromoles per square meter per second is ideal. With supplemental carbon dioxide at 1000 to 1200 parts per million, the canopy can utilize up to approximately 1100 to 1200 micromoles per square meter per second, improving yield by 10 to 20 percent if nutrition and irrigation are matched to demand.

Nutrition and pH: In soilless or hydroponic media, maintain pH at 5.7 to 6.0 in veg and 5.8 to 6.2 in flower. In living soil or peat-based mixes, 6.2 to 6.8 promotes micronutrient availability. Electrical conductivity targets are 0.6 to 1.0 millisiemens per centimeter for seedlings, 1.2 to 1.8 in veg, 1.6 to 2.0 in early flower, and 1.8 to 2.2 during weeks 4 to 6 of bloom, tapering thereafter.

Feeding specifics: After 8 OG, like many OG lines, responds well to elevated calcium and magnesium during high-intensity lighting. Supplement with 150 to 200 parts per million calcium and 50 to 80 parts per million magnesium when using reverse osmosis water. Potassium demand rises during bulking; ensure a strong K supply in mid to late bloom along with sulfur to support terpene synthesis.

Irrigation strategy: Maintain consistent wet-dry cycles in soil, watering to 10 to 20 percent runoff. In coco, aim for multiple smaller irrigations per day at peak transpiration to keep substrate EC stable, often 3 to 6 events depending on pot size and environment. Avoid root zone temperatures below 18 degrees Celsius to prevent slowed nutrient uptake.

Training and canopy management: Top or fim in week 3 or 4 of veg to establish 4 to 8 mains, then employ low-stress training or a single-layer screen of green to create an even canopy. OG-leaning plants stretch approximately 1.5 to 2.0 times after flip, so set the trellis 20 to 30 centimeters above the canopy prior to transition. Defoliate lightly at day 21 of flower to open airflow and again at day 42 if leaves are shading budsites, but avoid over-stripping, which can reduce yield.

Pest and disease prevention: Dense OG colas are susceptible to powdery mildew and botrytis in high humidity. Integrate an IPM routine with regular leaf-surface inspections, sticky cards, and, when allowed, beneficials such as predatory mites. Maintain leaf surface temperatures aligned with air temps to minimize dew point events and run dehumidifiers to keep late-flower RH near 45 percent.

Flowering timeline and cues: Visible bud set begins around day 10 to 14 after flip, with significant bulking from weeks 4 to 7. Many growers find peak maturity between days 56 and 63, depending on desired effect. Harvest earlier for brighter, more uplifting effects when trichomes are predominantly cloudy, and later, with 10 to 20 percent amber trichomes, for a more sedative finish.

Yield expectations: In dialed-in indoor conditions, After 8 OG typically yields around 350 to 500 grams per square meter, depending on veg time and light intensity. Outdoors, healthy plants in full sun and well-amended soil can reach 500 to 700 grams per plant in temperate climates. Structural support outdoors is crucial to keep colas upright during late-season winds.

Outdoor considerations: In the Northern Hemisphere, plant after the last frost and expect a mid to late September harvest at lower latitudes or early to mid-October at higher latitudes if the flowering window targets 8 to 9 weeks. Choose sites with strong morning sun and good airflow to reduce leaf wetness duration. Mulch to stabilize soil moisture and reduce irrigation frequency.

Harvest, drying, and curing: Wet-trim only the largest fan leaves, then hang whole plants or large branches in a dark room at 18 to 20 degrees Celsius and 58 to 62 percent relative humidity. Drying over 10 to 14 days preserves monoterpenes better than rapid dries and reduces chlorophyll notes. Expect a 70 to 80 percent weight loss from wet to dry flower; jar when stems snap but do not splinter.

Curing targets and storage: Cure in glass at 58 to 62 percent relative humidity, burping daily for the first week, then weekly for 3 to 4 weeks. Water activity between 0.55 and 0.65 inhibits mold while maintaining pliability and aroma. Properly cured After 8 OG retains aroma and potency for months when stored in airtight containers away from heat and light.

Post-harvest testing and quality: If possible, submit samples to a lab for cannabinoid and terpene profiling to track outcomes across runs. Document PPFD, EC, canopy temperature, and irrigation volumes to correlate cultural practices with potency and yield. Over successive cycles, this data-driven approach tightens variance and helps lock in the cultivar’s best expression.
