187 is a modern heirloom-style cultivar bred by Dominion Seed Company, a Virginia-born outfit known for reviving and stabilizing classic East Coast lines. Dominion built its reputation on regular seed releases, deep phenotype hunts, and rigorous selection for vigor, pest resistance, and throwback skunk and chem profiles. Within that philosophy, 187 emerged as a deliberate attempt to capture loud, old-school punch with contemporary resin production and garden reliability.
Public documentation on the exact year of 187’s first public drop is sparse, but the strain circulated among breeders and connoisseurs in the late 2010s as Dominion’s catalog expanded. Growers who followed Dominion’s work recognized 187 as part of the breeder’s push to consolidate skunk-leaning expressions without sacrificing structure or potency. This period saw a broader market trend toward gas, funk, and skunk aromatics as consumers searched beyond dessert terpene profiles.
The name 187 nods to a hard-edged personality and a no-nonsense chemotype that hits with authority. In community lore, it also reflects Dominion’s ethos of tough, field-ready stock that holds up under pressure and returns predictable performance. While hype cycles come and go, 187 carved a place among heads who prize classic terpenes and a purposeful, assertive effect curve.
Dominion Seed Company’s background provides critical context for understanding 187’s cultural position. The breeder’s ties to East Coast skunk and chem lines, including work historically associated with the Skelly and VA beach scenes, shaped expectations for 187 from the outset. Those expectations included a sharp, pungent nose, stout internodes, and dense calyx-stacking reminiscent of pre-dispensary era standouts.
As legal markets matured, cultivars like 187 offered a counterpoint to confectionary aromas by re-centering sulfuric skunk, fuel, and herbal spice. In buyer data from several U.S. markets, chem and skunk-leaning cultivars regularly rank among the top repeat-purchase categories, reflecting strong niche loyalty. 187 benefited from this preference, earning steady word-of-mouth based on its old-school-meets-modern balance.
Genetic Lineage and Breeding Rationale
Dominion Seed Company has not released a universally accepted, line-by-line pedigree for 187 in public breeder notes that are easy to source, and responsible writers acknowledge this gap. However, 187 is widely discussed in grower forums as an East Coast skunk and chem-influenced line consistent with Dominion’s catalog. That family of genetics typically descends from Skunk, Afghan, and Chemdog-adjacent ancestry, yielding dense flower, sharp volatile sulfur compounds, and robust resin.
The breeding rationale for 187 likely focused on three pillars that recur in Dominion projects. First, capturing skunk-forward terpenes that cut through a room even in a sealed container. Second, locking down plant structure that tolerates high light intensities, fluctuating humidity, and pressure from powdery mildew or mites better than many dessert cultivars. Third, balancing THC potency with a terpene ratio that produces fast-onset, chest-expanding effects.
Chemotype I dominance is a safe expectation based on the family of inputs typically used by Dominion Seed Company. Chemotype I plants express high THC with trace CBD, a profile that fits 187’s reported impact and market positioning. The breeder’s emphasis on stabilized regular seed lines means 187-grown-from-seed often reveals two or three meaningful phenotypic expressions, each with shared core traits.
Lineages shaped by Skunk and Afghan inputs often pass on characteristic broadleaf-dominant traits and thick, chunky calyx development. Chem ties add fuel, rubber, and solvent notes alongside a stimulating, head-forward onset. 187’s reputation within that ecosystem aligns with those hallmarks, even if the exact parental lines remain breeder-proprietary or scattered across community notes.
For growers and buyers, the practical takeaway is that 187 behaves like a modern, selected skunk-chem hybrid with an emphasis on resin coverage and unapologetically loud aroma. Expectations should include relatively uniform internode spacing, easily readable nutrient demands, and top-end bag appeal when cultivated with proper environmental controls. Phenotype selection can then refine toward either skunkier or gassier noses depending on the cut.
Appearance and Morphology
In flower, 187 typically presents as a medium-stature plant with sturdy laterals and moderate internodes that stack decisively under strong light. Buds are dense, golf-ball to soda-can sized, and skew toward a broadleaf-dominant look with tight, angular bracts. Mature colas often display a rich forest-to-lime-green backdrop accented by exuberant, orange-to-rust pistils.
Trichome coverage is a visual calling card, with a glassy layer of capitate-stalked heads that frost the calyces and sugar leaves. Under a loupe, heads trend toward medium-to-large diameters with even cap formation, a desirable trait for high-yield solventless work. Well-grown 187 shows minimal leaf-in-bud and trims into a clean, jewel-like silhouette.
Vegetatively, 187 accepts topping and low-stress training readily, forming an even table with two to four primary axes after initial pruning. Leaf morphology often features wide blades and a thick petiole, hallmarks of Afghan-influenced stock, while maintaining the vigor and elasticity of hybrid vigor. Plants respond well to canopy management, and lateral density benefits from selective defoliation in weeks three and six of flower.
In cured flower, bag appeal is driven by contrast and resin sheen. Darker sugar leaf tips, if left intentionally, frame the bright pistils and crystalline resin to dramatic effect. Properly dried buds resist compression and rebound with a firm, meringue-like give, a tactile signal of healthy internal moisture and resin integrity.
Growers frequently report that 187 maintains structure against wind and oscillating air, supporting tight SOG or SCROG approaches without spindly collapse. This resilience translates to consistent top-shelf visuals across different cultivation rooms, provided VPD and feed consistency are maintained. The result is a cultivar that looks premium even before the bag is cracked.
Aroma and Bouquet
Open a jar of 187 and the first impression is loud, assertive skunk laced with fuel and rubber, a sensory signature consistent with East Coast heritage. Secondary notes swing through garlic-onion funk, black pepper, and damp forest floor, suggesting a myrcene and caryophyllene axis with sulfuric volatiles. A bright, zesty top note akin to lemon rind sometimes flashes on the break, hinting at limonene or terpinolene adjacency depending on phenotype.
The grind intensifies the chem and skunk threads, adding adhesive and tire-shop nuances that linger in the room. Grind-to-nose intensity is high, and portable stash solutions often struggle to contain the bouquet, an attribute sought by users who prioritize unmistakable character. On the back end, a soft herbal sweetness reminiscent of sweet basil or fennel anise balances the heavier notes.
Terpene persistence is a key feature, with the aroma retaining depth days after the jar is first opened if storage is proper. The headspace tends to fill quickly, and some users describe an almost metallic snap in the nose that suggests high terpene concentration and potential volatile sulfur compounds. Roommates and neighbors will recognize 187 from down the hall, underscoring the need for carbon filtration during cultivation.
Dominant aromatic families map well onto the reported parentage themes even though specific parental lines are not publicly standardized. The skunk-fuel combination stands apart from modern candy-forward cultivars, appealing to enthusiasts seeking bold, savory complexity. In sensory panels, such profiles often score high for distinctiveness and memorability, two attributes correlated with repeat purchase in niche categories.
Flavor and Combustion Character
On inhalation, 187 carries pungent skunk and fuel that coat the palate quickly, backed by peppery spice that rolls across the tongue. The first two draws are often the loudest, with a retrohale that blooms into garlic, clove, and rubbery chem. A lemon-peel brightness can flash mid-bowl, especially in vaporized sessions at 180 to 190 C where top-note terpenes are preserved.
Combustion quality depends heavily on dry and cure, but well-finished 187 burns to a light gray ash and holds a tall, firm cherry. The smoke is dense yet not harsh when moisture content is targeted around 10 to 12 percent, and a steady cadence avoids overheating the bowl. Many users report a lingering savory aftertaste, like onion jam over charred citrus, that persists for several minutes post-session.
Vapor flavor layers more nuance, highlighting sweet herbal tones and a faint floral thread that can be masked in smoke. At lower temps, the myrcene-forward base feels round and slightly syrupy, while increasing temp unlocks caryophyllene bite and a denser mouthfeel. Terpene volatility makes storage and pack size critical, as oversized joints can mute higher volatiles by the final third.
Compared with dessert cultivars, 187’s profile reads more umami and resinous, with less overt confectionery sweetness. This positions it well for users who want a savory, culinary spectrum rather than candy and fruit. The flavor holds up in concentrates, too, where mechanical separation preserves the skunk-chem axis with remarkable tenacity.
Cannabinoid Profile and Potency
187 is best understood as a THC-dominant, chemotype I cultivar, a category that composes the majority of modern top-shelf market offerings. Across U.S. commercial datasets, chemotype I indoor flower commonly ranges from 18 to 25 percent delta-9 THC by dry weight, with outliers above 28 percent in exceptional lots. Total cannabinoid content in such samples typically lands between 20 and 30 percent when THCa and minor cannabinoids are included.
Direct, published multi-lab data for 187 specifically are limited in the public domain, so prudent estimates rely on analogous skunk-chem hybrid performance. Growers who have run 187 in optimized environments report potency competitive with leading skunk and chem lines, and resin density consistent with strong THCa conversion on decarb. As always, environment, harvest timing, and cure drive variance as much as genetics.
Minor cannabinoids in skunk and chem families often include trace CBG, CBC, and a small drift of CBN in older stock or extended cures. Measured CBG in THC-dominant lines commonly hovers around 0.2 to 1.0 percent, while CBC is often detected at 0.1 to 0.6 percent, though values depend on lab methodology. For 187, users should expect a standard THC-led effect with only incidental contributions from these minors.
Consumption method changes effective dose and perceived potency dramatically. Inhalation has a rapid onset within 1 to 10 minutes, with peak effects near 15 to 45 minutes and a typical duration of 2 to 4 hours. Oral ingestion leads to 11-hydroxy-THC formation in the liver, extending peak effects and increasing potency per milligram compared with inhaled delta-9 THC.
Terpene Profile and Secondary Metabolites
Reports from cultivators and users consistently point to a terpene hierarchy led by myrcene, beta-caryophyllene, and limonene in many 187 phenotypes. In North American lab surveys, these three terpenes collectively dominate roughly half of commercial chemotype I flower, and myrcene alone is the most common primary terpene in market data. Total terpene content for premium indoor lots often falls between 1.5 and 3.0 percent by dry weight, with elite examples creeping higher under ideal conditions.
Myrcene contributes to the earthy, resinous base and can synergize with THC to modulate perceived sedation at higher doses. Beta-caryophyllene imparts peppery spice and uniquely engages CB2 receptors as an agonist, a pharmacology detail that may influence inflammation signaling. Limonene adds citrus lift and can sharpen the top note, especially noticeable on dry pull and early puffs.
Secondary players likely include humulene, ocimene, and linalool at modest fractions. Humulene confers woody dryness and can subtly suppress appetite perception in preclinical contexts, while ocimene may lend a green, herbal snap. Linalool, if present, softens edges with a light floral component that occasionally rides the retrohale.
Of note, skunk-chem families can carry volatile sulfur compounds that contribute to the garlic-onion-rubber dimension. These compounds, present in parts-per-billion ranges, are disproportionately powerful to the human nose and explain why jars of 187 are difficult to keep discreet. Indoor carbon filtration and post-harvest handling are essential to preserve the good and control the overwhelming.
Experiential Effects and Onset
187 is widely experienced as fast-onset, chest-expanding, and assertively head-forward in the first 10 to 20 minutes. Users often report a sharpened sensory field, elevated heart rate, and a focused, energetic lift that can tip into intensity if the dose overshoots tolerance. As the peak settles, a grounding body weight often arrives, relaxing large muscle groups without immobilizing experienced consumers.
The effect arc typically follows a two-stage profile consistent with THC-dominant skunk-chem hybrids. Stage one emphasizes euphoria, talkativeness, and a stimulated internal monologue, with some users noting a creative or analytical flow. Stage two brings physical ease and appetite stimulation, with lingering calm in the shoulders and back.
Dose control strongly shapes the experience, and smaller inhalation puffs can maintain clarity without flooding the system. Many consumers find that one or two moderate draws are sufficient to capture the headspace without tipping into racing thoughts. Conversely, heavy sessions can produce a powerful, sometimes racy onset, especially in low-tolerance users.
Research synthesized by Hytiva on cannabis effects, including reference to Psychopharmacology volume 187 issue 1 pages 38 to 50, underscores THC’s dose-dependent cognitive changes. Controlled human trials consistently show acute impacts on attention, short-term memory encoding, and reaction time during peak intoxication. These findings align with 187’s lived reports and support the recommendation to avoid driving or safety-sensitive tasks during and after use until fully baseline again.
Duration is method-dependent, but inhalation commonly produces a 2 to 4 hour window of noticeable effects, with peak intensity in the first hour. The come-down is typically smooth if hydration and snacks are available, though sensitive users may experience transient dry mouth or anxiety. A peaceful, reflective afterglow is common, especially with a balanced, not excessive, intake.
Potential Medical Uses and Evidence
As a THC-dominant cultivar with a robust terpene engine, 187 may provide symptomatic relief in domains where high-THC chemovars are frequently utilized. Anecdotally, users report benefits for stress modulation, appetite stimulation, and short-term relief of tension-related headaches and muscle tightness. The peppery caryophyllene edge and relaxing myrcene base form a plausible mechanism for perceived comfort after the initial mental lift subsides.
Peer-reviewed literature supports several THC-related therapeutic effects, albeit with variability by individual and formulation. Inhaled THC has demonstrable antiemetic properties, appetite stimulation, and analgesic potential in certain neuropathic and cancer-related pain scenarios, though evidence grades differ by indication. Beta-caryophyllene’s CB2 activity may contribute adjunct anti-inflammatory signaling, while limonene has been investigated for mood-related effects in preclinical and early human contexts.
Hytiva’s overview of cannabis’s impact on the body and brain, referencing Psychopharmacology research, reinforces that benefits and impairments are tightly dose-governed. For some patients, small inhaled doses deliver functional daytime relief with minimal cognitive cost, while larger doses may impair memory and attention temporarily. Careful titration, journaling, and clinician-guided experimentation remain best practices.
Potential use cases for 187 align with high-THC standards rather than CBD-rich niches. Individuals seeking relief from low appetite, stress spikes, or transient musculoskeletal discomfort may find 187 fits an evening or post-task slot. Those with anxiety sensitivity can consider microdosing approaches or pairing with cannabidiol to moderate intensity, acknowledging that CBD ratios in 187 itself are typically low.
Medical decisions should always be individualized and coordinated with a healthcare professional, particularly for people with cardiovascular conditions, psychiatric histories, or polypharmacy. THC can transiently increase heart rate and may interact with medications metabolized by CYP450 enzymes. Responsible selection and conservative initial dosing improve the therapeutic index and reduce adverse experiences.
Comprehensive Cultivation Guide
187 rewards disciplined environment control and benefits from a medium-to-high energy cultivation style. The cultivar tolerates aggressive light levels when acclimated, responds well to canopy management, and appreciates steady root-zone oxygenation. Across methods, target consistency outweighs chasing absolute maxima.
Propagation and early veg are straightforward. Maintain 24 to 26 C air temperature with 60 to 70 percent RH for clones and seedlings, tapering RH to 55 to 60 percent by late veg to hit a VPD of roughly 0.8 to 1.1 kPa. Use gentle light at 250 to 400 µmol m⁻² s⁻¹ PPFD for rooted cuts, increasing to 500 to 700 µmol m⁻² s⁻¹ by late veg with a DLI of 20 to 30 mol m⁻² day⁻¹.
Training 187 into a broad, even canopy is effective. Top once at the fifth node, then again as needed to create two to four mains, and combine with low-stress training to keep verticals level. Remove weak interior shoots and lollipop the bottom 20 to 30 percent of the plant a week before flip.
During early flower, 187 will stretch moderately, often 1.5x to 2.0x its veg height depending on phenotype and light spectrum. Set flower temps at 24 to 27 C lights-on and 20 to 22 C lights-off, holding RH near 50 to 55 percent in weeks one to three to maintain a 1.1 to 1.3 kPa VPD. After week three, trim RH to 45 to 50 percent to defend against botrytis in dense colas.
Light intensity in bloom can be driven to 800 to 1,050 µmol m⁻² s⁻¹ PPFD on LEDs with CO2 at 800 to 1,100 ppm if plants are well-fed and transpiring. Without CO2 supplementation, keep PPFD closer to 700 to 900 µmol m⁻² s⁻¹ to avoid photoinhibition. Canopy uniformity is essential; a four-inch light-to-canopy variance can translate to uneven ripening.
Nutritionally, 187 favors balanced macro ratios with steady calcium and magnesium availability. In soilless systems, many growers find success in the 1.8 to 2.3 mS cm⁻¹ EC range through mid-flower, tapering to 1.2 to 1.6 mS cm⁻¹ in the final two weeks depending on leaf color and runoff readings. Keep nitrogen modest post week three to avoid leafy buds, and frontload phosphorus and potassium for stack and density.
Media choices include coco, peat mixes, and living soil, each with tradeoffs. Coco with high-frequency fertigation supports rapid growth and precise steering, with two to five irrigations per day at peak transpiration delivering 10 to 20 percent runoff. Living soil emphasizes microbe-led nutrition and can intensify terpene expression when teas and top-dresses are well-timed.
Airflow and dehumidification are non-negotiable for 187’s tight bud structure. Employ two airspeeds in flower rooms, a gentle canopy breeze and stronger crossflow above lights to disrupt stratification. Size dehumidifiers to maintain setpoints even immediately after lights-off, when transpiration surges.
Regarding integrated pest management, start prophylaxis in veg with biologicals like Bacillus subtilis for powdery mildew suppression and regular leaf inspections. Sticky cards at canopy and under-canopy height help track winged pests, while predatory mites can be introduced preventatively if history suggests risk. Avoid late-flower sprays to preserve resin and avoid residue in the finished product.
Flowering time for 187 generally lands in the 8 to 10 week window depending on phenotype and grower preference for effect. Skunk-leaning phenos can finish on the earlier side with a headier profile at 8.5 weeks, while deeper chem phenos benefit from 9.5 to 10 weeks for full terpene maturation. Monitor trichome heads rather than calendar alone to decide the exact day.
Harvest timing should be guided by trichome color and head integrity. Many growers target mostly cloudy heads with 10 to 20 percent amber for a balanced, potent effect that preserves top notes. Clear-headed harvests may feel racier, while heavy amber drifts sedative and can blur the skunk brightness.
Drying parameters determine combustion quality and terpene retention. Aim for 10 to 14 days at 16 to 18 C with 58 to 62 percent RH, low airflow across but not on the flowers, and total darkness. Whole-plant or large-branch hangs slow the dry and help even moisture migration, reducing the risk of hay aromas.
Curing locks in 187’s signature nose. After trimming, jar or bin at 60 to 62 percent RH and burp daily for a week, then weekly for the next three to four weeks as the internal moisture equilibrates. Water activity between 0.55 and 0.65 and final moisture content near 10 to 12 percent support shelf stability and smooth smoke.
Yield potential reflects environment and method. Under dialed LEDs with healthy CO2, expect 450 to 650 grams per square meter in SCROG or a grams-per-watt range of 0.8 to 1.5 depending on cultivar expression and grower skill. Solventless processors value 187’s trichome density; wash yields vary, but skunk-chem hybrids often return 4 to 6 percent fresh frozen in favorable cuts.
Post-harvest storage safeguards potency. Keep sealed inventory at 2 to 8 C if possible, protected from light, and avoid repeated freeze-thaw cycles. Over months at room temperature, THCa decarboxylates and THC oxidizes to CBN; minimizing oxygen and heat slows these kinetics and preserves 187’s punch and aroma.
For outdoor and greenhouse runs, select sites with strong midday sun and reliable late-season air movement. Dense colas mandate aggressive de-leafing and mildew-resistant cultural practices, including wide plant spacing and early trellising. In wetter climates, hoop houses and heat-assisted dehumidification can be the difference between A-grade and botrytis losses.
Finally, phenotype selection sharpens results across cycles. Run multiple seeds if available, track vigor, internode spacing, mildew tolerance, and terpene loudness, then lock in the cut that retains aroma through dry and cure. 187 rewards this work with a consistently top-tier representation of skunk-chem character when the best expression is found.
