Lime Urkle is an indica-leaning cultivar developed by Sin City Seeds, a breeder known for resin-rich, flavor-forward hybrids. As its name hints, the strain blends zesty lime aromatics with the grape-and-berry undertones associated with the Urkle family. The result is a dense, colorful flower that balances dessert-like sweetness with mouthwatering citrus snap.
Growers and consumers report a profile that is simultaneously comforting and vivid. The indica heritage often translates to a relaxing body experience, while the lime-driven terpenes keep the sensory experience bright and engaging. For many, Lime Urkle occupies a sweet spot between evening-ready calm and daytime-friendly clarity in modest doses.
While definitive, lab-verified datasets for this specific variety are limited in the public domain, its relatives provide a credible guide to expected potency and terpene composition. Modern indica-dominant hybrids commonly test in the upper teens to mid-twenties for THC, with CBD typically below 1 percent unless specifically bred for it. Lime Urkle follows that contemporary pattern, emphasizing robust THC alongside a terpene ensemble that elevates flavor and effect.
Breeding History and Provenance
Sin City Seeds has built a reputation for crossing popular clone-only lines with carefully selected males to produce progeny with improved resin output, richer flavor arcs, and reliable vigor. Lime Urkle sits within that tradition as a mostly indica selection designed to push citrus tones into the classic Urkle palette. The breeder affiliation is important context; Sin City Seeds strains such as SinMint and White Nightmare are known for strong terpene expression and photogenic trichome coverage.
Urkle genetics originate from Northern California, tracing back to 1980s and 1990s purple indicas that emphasized heavy body relaxation, grape-candy aromas, and dense structure. By pairing that lineage with a lime-forward counterpart, the creators sought to intensify top-note brightness without sacrificing the calming base. The end product aims at connoisseurs who prioritize boutique aroma while also valuing consistency in growth habits.
The mostly indica designation reflects the parental balance used by the breeder, leaning toward compact internodes, swift flowering, and thick calyx stacks. In practical terms, this heritage reduces stretch and supports canopy management in smaller spaces. For home growers and small craft gardens, those traits translate to predictability, which is often as valuable as raw potency.
Genetic Lineage and Indica Heritage
The Urkle family, anchored by Purple Urkle and associated Mendocino heritage, is synonymous with broad-leaf morphology, dense buds, and deeply relaxing effects. Although the exact lime donor in Lime Urkle is not publicly codified in breeder notes, the citrus-forward influence is unmistakable in both aroma and palate. That interplay suggests a convergence of limonene-rich citrus parentage with the myrcene- and caryophyllene-weighted Urkle baseline.
Indica-leaning hybrids, especially those connected to Urkle, traditionally demonstrate a flowering period near the eight-to-nine-week mark under 12 hours of light. Their canopies tend to be compact, and they respond well to topping and scrogging to build uniform bud sites. Lime Urkle aligns with those traits, offering modest stretch and a strong preference for even light distribution.
For phenotype expression, expect two broad lanes: a lime-dominant nose with subtle grape undertones, and a more balanced citrus-grape bouquet that blooms sweeter post-cure. Both remain in the indica domain, but the lime-heavy pheno can feel a touch more heady at the onset due to its zesty terpene focus. Growers often select mothers that combine the lime top note with Urkle density to maximize both bag appeal and yield.
Visual Morphology and Bag Appeal
Lime Urkle typically presents dense, golf-ball to egg-shaped colas with tight calyx stacking and minimal foxtailing when environmental stress is controlled. The coloration ranges from vivid lime-green to deep forest hues, often threaded with purple streaks inherited from the Urkle side. Pistils lean orange to copper, providing high-contrast visual interest against a sugar-coated trichome field.
Trichome coverage is a standout feature, forming a frosty layer that catches light and signals resin abundance. Under magnification, bulbous heads are plentiful, a positive indicator for both terpene retention and extraction potential. This trait aligns with Sin City Seeds selections that emphasize resin mass on the calyx surface.
Structure at the branch level trends toward firm lateral growth with moderate internode spacing. With proper training, growers can shape a flat canopy that flowers evenly and reduces larfy lower buds. The combination of weighty tops and sturdy branches means stakes or a trellis net are still recommended during the final three weeks of bloom to prevent leaning.
Aroma Profile: From Grind to Exhale
On first approach, Lime Urkle offers a bright squeeze of lime peel, reminiscent of lime zest expressed over a glass. This top note often carries a sugared edge, like lime candy or key-lime sherbet. Secondary layers include grape skin, light berry preserves, and a faint herbal spice that lifts on the grind.
When broken up, the citrus expands and becomes more tart and pithy, suggesting a limonene-forward profile with support from caryophyllene and ocimene. The Urkle base emerges as a sticky sweetness that rounds the acid edge into a pastry-like bouquet. Some phenotypes also display a cool floral whisper, likely from linalool, which softens the overall aromatic arc.
Post-combustion, the room note balances confectionery sweetness with fresh citrus oils. In vaporizers, expect clearer segregation of notes: lime in the low- to mid-temperature ranges, followed by grape-floral elements as the temperature rises. A clean cure accentuates the lime and prevents the profile from collapsing into generic skunk.
Flavor Profile and Consumption Experience
The first draw typically brings a lemon-lime soda pop impression, but with a more natural lime-oil concentration than simple sweetness. As the session continues, the flavor deepens into grape candy and berry tarts, anchored by a faint peppery spice on the exhale. The aftertaste is pleasant and lingering, with citrus oils coating the palate.
Combustion at lower temperatures preserves the bright citrus and delivers a smoother inhale with minimal throat bite. As temperatures rise, the peppery and herbal tones get louder, reflecting caryophyllene and humulene activation. Using a clean glass piece or a well-maintained vaporizer helps maintain the pastry-sweet spectrum without introducing char flavors.
Edibles made with Lime Urkle often carry a creamsicle-meets-lime-curd imprint if the infusion is done at moderate temperatures to preserve terpenes. Full decarboxylation will mute some top notes, so confections benefit from added lime zest or citrus peel to mirror the strain’s natural character. Concentrates derived from standout phenotypes can be remarkably aromatic, making live resin and rosin particularly appealing formats.
Cannabinoid Profile and Potency Data
Indica-dominant hybrids similar to Lime Urkle frequently test between 18 and 26 percent THC in contemporary markets, with outliers on either side depending on phenotype selection and cultivation variables. CBD is typically limited, commonly below 1 percent, unless a CBD-rich parent was introduced, which is not indicated in the Lime Urkle context. Minor cannabinoids such as CBG often appear in the 0.1 to 1.0 percent range in modern resinous cultivars.
From a user-experience standpoint, that THC range usually supports a rapid-onset euphoria with progressive body relaxation. Novice consumers should start low, especially with concentrates, as the lime-forward aroma can mask potency and invite larger pulls. For inhalation, a conservative first dose might be a single small inhalation, waiting 10 to 15 minutes before redosing to assess subjective effects.
Cultivation variables can swing potency measurably. Lighting intensity, harvest timing, and post-harvest handling all impact final THC measurement, with over-drying or harsh curing environments reducing terpene retention and perceived strength. In well-optimized indoor environments, growers targeting a daily light integral of roughly 35 to 45 mol per square meter can reasonably expect strong resin development and competitive potency.
Terpene Profile and Chemical Contributors
The lime signature points to limonene as a key terpene, often supported by beta-caryophyllene and myrcene in indica-leaning crosses. In many citrus-dominant profiles, limonene can land anywhere from 0.4 to 1.5 percent of dry weight under careful cultivation, though results depend on genetics, environmental control, and cure quality. Myrcene commonly sits in the 0.4 to 1.2 percent window for broad-leaf indica backgrounds, contributing to herbal sweetness and body heaviness.
Beta-caryophyllene, a sesquiterpene with peppery spice, frequently ranges from 0.3 to 1.0 percent in modern resinous cultivars and is notable for CB2 receptor affinity. Linalool, though generally lower, can provide a floral varnish that softens citrus sharpness, often registering between 0.05 and 0.3 percent. Ocimene and humulene may add green, woody top notes and a crisp finish to the lime-grape duet.
In the sensory glass, these compounds interact synergistically. Limonene sets the bright stage, caryophyllene and humulene add structure and light bitterness, myrcene deepens sweetness, and linalool offers a calming floral glaze. The overall effect is a layered terpene canvas that tastes like dessert but finishes refreshing and clean.
Experiential Effects and Functional Use
Lime Urkle’s indica foundation tends to produce a steady wash of body relaxation, with a head space that starts clear and turns softly introspective. The citrus tilt often brings an initial lift in mood, helpful for unwinding after work without immediate couch-lock. As the session deepens, the Urkle body feel becomes more pronounced, easing muscle tension and promoting calm.
Onset for inhaled formats commonly arrives within 2 to 5 minutes, peaks by 20 to 30 minutes, and can persist for 2 to 3 hours. Edible formats extend both onset and duration, with effects lasting 4 to 8 hours depending on dose and metabolism. Many users report that lower doses support focus and light creativity, while larger doses favor movies, music, and sleep readiness.
Side effects match the usual THC profile: dry mouth, dry eyes, and possible transient short-term memory fuzziness at higher doses. Those sensitive to limonene-forward strains should test in small amounts, as bright terpenes can feel stimulating before the indica body settles in. Hydration and pacing are simple, effective strategies for a smoother experience.
Potential Medical Uses and Patient Considerations
Patients often explore indica-dominant, citrus-forward strains like Lime Urkle for stress reduction and evening wind-down. The combination of limonene, myrcene, and caryophyllene may support mood elevation while also modulating discomfort and tension. Beta-caryophyllene’s interaction with CB2 receptors is frequently cited in the literature discussing inflammation pathways, although human evidence remains evolving.
Sleep difficulty is another common target for Urkle-descended cultivars. While Lime Urkle can feel bright at first, the secondary wave often leans sedative, particularly at higher doses or in edible formats. Patients with insomnia may benefit from timing use 60 to 90 minutes before intended sleep, starting with small amounts to gauge next-day grogginess.
Those managing pain and muscle spasms sometimes find value in Lime Urkle’s body-forward relaxation in the latter half of the effect window. Gastrointestinal comfort and appetite stimulation are also typical outcomes in indica-leaning THC varieties. As always, medical use should be coordinated with a clinician, especially for individuals taking medications that interact with the endocannabinoid system.
Cultivation Guide: Environment, Nutrition, and Training
Lime Urkle’s mostly indica heritage thrives in controlled environments where temperature, humidity, and light intensity can be finely tuned. Aim for vegetative day temperatures of 24 to 28 Celsius and nights 3 to 5 degrees cooler to maintain vigor. During flowering, 22 to 26 Celsius with a similar night drop keeps color expression and resin production on track.
Relative humidity should sit near 60 to 70 percent in veg, stepping down to 50 to 55 percent in early flower and 42 to 48 percent in late flower to limit botrytis risks. VPD targets of 0.8 to 1.2 kPa in veg and 1.2 to 1.5 kPa in flower promote consistent transpiration and nutrient flow. Air exchange and canopy-level airflow are essential; use oscillating fans to discourage microclimates where powdery mildew can take hold.
Lighting intensity in veg can range from 300 to 500 µmol per square meter per second PPFD, rising to 600 to 900 PPFD in mid-to-late bloom. Many growers target a daily light integral near 35 to 45 mol per square meter per day in flower for resin and yield synergy. Keep photoperiod at 18 to 20 hours in veg, then switch to 12 hours for flowering to maintain predictable finishing times.
Nutrient strength should be moderated for an indica that packs dense flowers. In soilless media such as coco, aim for a pH of 5.8 to 6.0 and EC of 1.2 to 1.6 mS per cm in veg, increasing to 1.8 to 2.2 mS per cm in peak bloom. In soil, pH should sit between 6.2 and 6.8 with EC guided by runoff and plant response.
Training works best with topping or fimming at the fourth to sixth node, followed by low-stress training to widen the canopy. A single or double-layer trellis provides support during weeks five through eight of flower when colas densify. Leaf removal should be targeted; thin large fan leaves that cast shade over interior bud sites, but avoid aggressive stripping that can stress indica phenotypes.
Watering cadence depends on pot size and environment, but many indoor gardeners find a rhythm of once per 1 to 2 days in coco under strong light, or every 2 to 4 days in well-amended living soil. Allow for 10 to 15 percent runoff in drain-to-waste coco to prevent salt buildup. In living soil, err on the side of slightly drier cycles to maintain oxygenation and prevent root rot.
Flowering Time, Harvest Windows, and Curing
Most Urkle-descended, indica-leaning cultivars finish between 56 and 66 days of 12-hour flowering, with some phenotypes preferring the 63-day mark for optimal terpene and resin maturity. Lime-forward phenos may look finished early due to rapid trichome frosting, but trichome color and calyx swell should guide the final call. A common harvest target is cloudy trichomes with 10 to 20 percent amber for a balanced head-to-body effect.
Pre-harvest flush is a grower preference; in inert media, 7 to 10 days of reduced EC or plain water helps the plant consume stored nutrients. In organic systems, switch to microbe-friendly, low-salt inputs and allow the plant to naturally taper. Darkness periods before chop are debated; if used, keep them short to avoid unwanted moisture spikes.
Drying at 60 Fahrenheit and 55 to 60 percent RH for 10 to 14 days is a widely used baseline to preserve terpenes. Aim for a final moisture content near 10 to 12 percent and a water activity of roughly 0.55 to 0.65 to stabilize aromatics. Curing in airtight jars with gentle burping over 2 to 4 weeks polishes the lime-grape bouquet and smooths the smoke meaningfully.
Pest and Pathogen Management
Like many dense-flowering indicas, Lime Urkle is susceptible to botrytis in the final weeks if humidity spikes or airflow is inadequate. Preventative strategies include strict defoliation discipline, strong horizontal airflow, and keeping late-flower RH under 50 percent. Regular canopy inspections with a small flashlight can catch early gray mold before it spreads.
Spider mites and thrips can appear in indoor gardens, especially under warm, dry conditions. Integrated pest management works best when it starts early with weekly scouting, sticky cards, and biological controls such as predatory mites where permitted. Foliar applications should be discontinued by the second or third week of flower to avoid residue and terpene interference.
Powdery mildew thrives in stagnant air and high humidity deltas between day and night. Maintain steady environmental transitions, sanitize tools and surfaces, and quarantine new plant material. A stable VPD and clean intake filtration dramatically reduce pathogen pressure across the entire run.
Yield Expectations and Quality Optimization
Under optimized indoor conditions, indica-leaning hybrids commonly produce 400 to 600 grams per square meter, with top-tier phenotypes and dialed-in CO2 occasionally pushing higher. In outdoor settings with full sun and good soil, individual plants can yield 450 to 900 grams, depending on veg duration and training. Lime Urkle’s compact structure favors high-quality mids-to-tops and minimizes larf when light penetration is managed.
Quality spikes when light intensity is balanced with temperature and nutrition to avoid tip burn and terpene volatilization. Keep canopy leaf surface temperatures 1 to 2 degrees Celsius above ambient air under LEDs to maintain metabolic pace. Avoid late-flower nitrogen; instead, emphasize potassium and sulfur availability for terpene biosynthesis during weeks five to eight.
Post-harvest handling is a yield in disguise. Even a small increase in terpene retention can translate to stronger perceived potency and higher bag appeal. Gentle trimming, controlled drying, and a patient cure routinely make the difference between good and exceptional outcomes.
Post-Harvest Chemistry: Storage, Decarboxylation, and Stability
THC and terpene stability depend on light, heat, oxygen, and time. Store finished flower in opaque, airtight containers at 15 to 20 Celsius and 55 to 62 percent relative humidity to slow degradation. Avoid frequent container opening, which exchanges terpene-rich headspace with ambient air and dilutes aroma.
Decarboxylation converts THCA to THC, typically around 105 to 120 Celsius for 30 to 60 minutes when preparing infusions. Lower-and-slower approaches can preserve more terpenes and maintain the lime top note, especially when the infusion is later incorporated into chilled desserts. For concentrates, cold storage is especially helpful; many citrus-forward extracts retain vibrancy longer when kept at refrigerator temperatures.
Overdry flower can test fine for cannabinoids but present flat in sensory evaluation. Rehydration with humidity packs can restore texture, but it cannot fully replace terpenes lost to volatilization. Protecting the lime-driven bouquet from the start is the most reliable route to lasting quality.
Comparisons and Context Within the Urkle Family
Traditional Urkle expressions lean grape, berry, and earth, with heavy-lidded effects that favor evenings and sleep. Lime Urkle modernizes that profile by adding a top-note citrus spark that widens use cases into late afternoon and early evening. Compared to a pure Purple Urkle expression, Lime Urkle is more zesty on the nose and often feels lighter in the head during the first half-hour.
Against other citrus-leaning indicas, such as lime-influenced cookie or kush crosses, Lime Urkle often tastes sweeter and more confectionary once cured. The Urkle base provides a pastry-like backbone that is distinct from strictly sour or diesel citrus types. For flavor hunters, it sits in the dessert-citrus category rather than the fuel-citrus lane.
Extraction-wise, Lime Urkle competes with top-tier citrus strains when the selected phenotype carries high limonene and adequate supporting sesquiterpenes. The resin’s visual frost is matched by tangible aroma in stable concentrates. That said, phenohunting to find a mother with a firm lime anchor is the surest path to consistently standout results.
Phenotype Selection and Stabilization
Start with a small population and flower out multiple females to observe nose, structure, and ripening behavior. Track metrics such as internode spacing, leaf size ratio, and terpene expression at weeks six and eight in flower. When possible, use simple sensory blind tests with a few trusted tasters to reduce bias when selecting keepers.
Desirable Lime Urkle phenos display a clear lime top note on stem rub by late veg, maintain that note through dry and cure, and yield dense, uniform colas without excessive staking. On the effect side, aim for a phenotype that lifts mood without early fog and settles into a forgiving, body-friendly finish. Keep detailed logs of feeding, environment, and harvest timing to correlate conditions with final aroma density.
Clone and re-run the top two or three candidates to validate that the observed performance is stable. If available, third-party lab terpene and potency tests on finalists can quantify differences and guide a long-term production choice. Over time, a dialed mother will repay the effort in both yield and unmistakable lime-grape character.
Responsible Use, Tolerance, and Safety
As with any THC-rich cultivar, start with low doses and increase slowly, especially if returning after a tolerance break. The citrusy bouquet can invite deeper draws, but potency is not diminished by sweetness or freshness of flavor. Plan for a comfortable setting and hydration, particularly if you are new to indica-leaning varieties.
Tolerance rises with frequent use; rotating strains and scheduling occasional breaks can help maintain desired effects at lower amounts. Avoid combining Lime Urkle with alcohol or sedative medications without medical guidance. Never drive or operate heavy machinery while under the influence, and store all cannabis products securely away from children and pets.
For medical users, track dose, format, and outcomes in a simple log. Over a few sessions, patterns will emerge that help you fine-tune timing and amounts. Discuss your observations with a healthcare professional to integrate cannabis use safely into your broader care plan.
