Madds Urkle Queen is an indica-leaning cultivar developed by Madd Farmer Genetics, a breeder known for preserving and reworking classic Northern California lines. The strain’s name signals a strong Purple Urkle influence, with a structure and effect profile that favor restful, body-forward experiences. For consumers and growers alike, Madds Urkle Queen occupies the niche of dense, resin-rich flowers with a grape-and-berry bouquet that performs reliably in indoor gardens.
While comprehensive, lab-verified datasets for this specific cultivar are limited, its behavior mirrors other Urkle-forward lines with a similar chemotype. Indica-dominant cultivars tend to deliver shorter flowering times, tighter internodes, and relatively high calyx-to-leaf ratios. Madds Urkle Queen checks all of those boxes, making it a compelling choice for small-scale growers seeking manageable canopies and market-ready bag appeal.
The strain’s heritage is mostly indica, aligning with reports of compact growth and heavy secondary metabolite production. Typical use cases include evening relaxation, sleep support, and post-activity recovery. For extraction work, its resin density and terpene fidelity can yield above-average returns if harvest and cure are dialed in.
From a sensory standpoint, expect deep purple hues under cool-night conditions and a flavor set reminiscent of classic purple cultivars. The aromatic profile typically leans sweet and earthy with berry-forward top notes and a subtle spice finish. Across phenotypes, users commonly describe a calm onset that develops into a full-body melt without overwhelming cognitive fog when dosed conservatively.
History and Breeder Background
Madd Farmer Genetics is widely associated with the stewardship of heritage Northern California cannabis lines, particularly those tied to Purple Urkle and other classic indica chemotypes. The breeder has prioritized regular seeds and preservation-minded crosses to retain vigor and phenotypic diversity. Madds Urkle Queen emerged from this ethos, consolidating a recognizable Urkle signature while dialing in structure and resin output.
Historically, Purple Urkle and its relatives are tied to the Emerald Triangle’s purple family, which includes Mendo Purps and other long-standing West Coast selections. These cultivars gained popularity during the 1990s and 2000s for their unmistakable grape aroma and night-friendly effects. Madd Farmer’s approach typically emphasizes stabilizing those legacy traits while improving cultivation efficiency.
As legal markets expanded in the 2010s and beyond, demand for terpene-forward purple flower surged, with consumer surveys repeatedly ranking berry and grape profiles among top preferences. Indica-dominant purple strains often command strong visual appeal, with dispensary shelf price premiums associated with deep color expression and bag aroma intensity. Madds Urkle Queen arrived into that landscape as a targeted answer for both connoisseur flavor and straightforward canopy management.
The breeder’s reputation for robust, Urkle-influenced lines creates a consistent expectation of cyclopedic purple aromas and sedative leanings. While the exact release timeline for Madds Urkle Queen is not formally published, the strain is recognized by growers who seek the archetypal Urkle experience in updated form. This positions it as a bridge cultivar: old-school essence with improved modern performance.
Genetic Lineage and Inheritance
The exact parentage of Madds Urkle Queen has not been publicly disclosed by Madd Farmer Genetics, but naming conventions and breeder focus indicate a dominant Purple Urkle backbone. The Queen moniker often signals a pairing with a vigorous, resinous counterpart or a queen phenotype designation within a line. In effect, growers should anticipate an Urkle-dominant expression shaped by selective breeding for structure and secondary metabolites.
Purple Urkle itself is widely considered a mostly indica heirloom that transmits grape-candy aromatics, compact canopy architecture, and heavy trichome coverage. These traits are strongly heritable and appear consistently across Urkle-forward progeny. As a result, Madds Urkle Queen tends to present stout lateral branching, short internodes, and high calyx density even when grown from seed.
From a practical standpoint, this inheritance predicts a moderate stretch in early flowering, typically between 1.2x and 1.6x under most indoor conditions. Dense inflorescences are the rule, raising both yield potential and humidity management needs. Expect phenotypes that respond exceptionally well to topping and screen-of-green, with faster-than-average flower set after the flip to 12 hours of light.
Given its mostly indica heritage, the chemotype profile should skew toward myrcene, caryophyllene, and limonene as primary terpenes. The cannabinoid outcome is typically THC dominant with minor CBD and trace CBG, closely mirroring Purple Urkle descendants. Breeding intent appears to stabilize the signature Urkle bouquet while standardizing structure for predictable garden performance.
Morphology and Appearance
Madds Urkle Queen grows squat and bushy in vegetative stages, with thick petioles and close internodal spacing. Leaves are broad and dark forest green, a visual cue for the indica-leaning genotype. Under cooler night temperatures of 16–19°C during late flower, anthocyanin expression intensifies, yielding purple to deep violet calyxes and bracts.
The flowers are dense, golf-ball to soda-can shaped colas with a high calyx-to-leaf ratio that simplifies post-harvest trimming. Trichome coverage is heavy by week five of bloom, increasingly opaque by week seven. Pistils begin a pale cream to light orange and mature toward copper as harvest approaches.
Indoor plants commonly reach 70–100 cm after training in a 60-day veg, though untrained individuals can exceed 120 cm with a longer vegetative period. Outdoor expressions stay relatively compact compared to sativa-dominant cultivars, topping 150–200 cm in fertile soil by late season. This manageable stature suits small tents, low-ceiling basements, and greenhouse benching.
Bag appeal benefits from a juxtaposition of purple tones against a silver-white resin sheen, a combination that markets well. Consumers often remark on the glassy trichome heads, which can be observed under 60–100x magnification as fully formed glandular bulbs. The visual signature aligns with premium-grade indica flowers known for high density and resin saturation.
Aroma and Bouquet
The dominant aromatic impression is grape and mixed berries, supported by earthy undertones and a faint peppery spice. When broken apart, buds release sweet, jam-like notes alongside hints of blackcurrant and plum skin. A secondary layer of incense and woodland soil becomes evident after a few seconds in open air.
Terpene drivers of this bouquet typically include myrcene and beta-caryophyllene, with limonene adding citrus-laced brightness. Linalool and ocimene may contribute to the floral and fruity top notes, especially in cooler cures. Freshly ground material tends to express more citrus and floral, while jarred, cured flower leans deeper into grape candy.
Aromatics intensify as relative humidity in the jar stabilizes around 58–62 percent, which preserves volatile compounds while preventing terpene evaporation. In sensory panels, purple cultivars often score high on perceived sweetness and nostalgia, aligning with consumer demand data for dessert-like profiles. Madds Urkle Queen meets that demand with a balanced, layered bouquet rather than an overpowering single-note.
Compared with many modern fruit-forward hybrids, there is less overt gas and more confectionery berry character. However, a background musk prevents the aroma from becoming cloying, adding dimensionality for repeat enjoyment. The result is an aroma set that radiates strongly in grinders and lingers on the fingers after handling.
Flavor and Palate
On the palate, Madds Urkle Queen delivers a distinct grape-berry entry that many associate with Purple Urkle lineage. Initial inhales can resemble blackberry jam with a mild citrus sparkle, likely from limonene interplay. Exhales layer in earth, vanilla, and a pinch of black pepper from caryophyllene.
Vaporization at 175–190°C highlights the sweet, fruity top notes and preserves floral linalool contributions. At combustion temperatures, deeper earth and cocoa tones emerge, maintaining balance without harshness when properly cured. Users often report a persistent aftertaste of grape peel and faint spice.
Terpene expression can vary with cure technique and duration. Slow drying over 10–14 days at approximately 60°F and 60 percent RH typically retains brighter fruit flavors. Curing for 3–6 weeks further rounds the edges, reducing grassy chlorophyll remnants and boosting perceived sweetness.
In extractions, rosin presses in the 180–195°F range frequently produce a syrupy, dark-straw sap with a sweet-berry nose. Hydrocarbon extracts can intensify the grape candy dimension, whereas live resin captures fresher citrus and floral accents. Across formats, the flavor profile remains anchored by berry and grape, with earth and spice as complementary accents.
Cannabinoid Profile and Potency
Formal, peer-reviewed lab results for Madds Urkle Queen are limited in the public domain, but the line behaves like a THC-dominant, mostly indica cultivar. Based on comparable Urkle-forward varieties, expect total THC commonly in the 18–24 percent range in well-grown indoor flower. Some phenotypes and top-shelf runs can exceed 25 percent THC, though this is not guaranteed and depends on environment and harvest timing.
CBD is generally minimal, often testing below 0.5 percent in Urkle-dominant lines. Total minor cannabinoids such as CBG typically register between 0.1 and 0.8 percent. Total cannabinoid content across quality indoor batches often lands in the 20–28 percent range when summing THC, THCa, and minors.
Potency outcomes correlate strongly with light intensity and plant health. Indoor PPFD levels of 700–900 µmol·m⁻²·s⁻¹ in weeks 3–7 of flower commonly support higher THCa accumulation, provided CO2 and nutrition are properly balanced. In side-by-side grower trials, dialing PPFD from 600 to 850 with adequate CO2 (900–1,100 ppm) can increase cannabinoid totals by 5–15 percent, though strain-specific responses vary.
Harvest maturity also influences potency. Pulling at the milky-to-early-amber trichome window typically ensures maximum THCa before oxidative degradation into CBN. Overmature harvests can reduce THC by 5–10 percent relative to peak, while increasing sedative feel via modest CBN formation.
Method of consumption changes perceived potency. Vaporization often feels cleaner but can produce a faster, clearer onset compared to combustion. Edibles formulated from this chemotype produce a delayed, more intense body effect due to 11-hydroxy-THC formation during hepatic metabolism.
Terpene Profile and Minor Aromatics
In Urkle-dominant cultivars similar to Madds Urkle Queen, myrcene frequently anchors the profile at 0.5–1.2 percent by weight in dried flower. Beta-caryophyllene often follows at 0.2–0.6 percent, contributing pepper and clove nuances while interacting with CB2 receptors. Limonene commonly appears in the 0.2–0.5 percent range, adding citrus brightness and perceived sweetness.
Supporting terpenes may include linalool (0.1–0.3 percent), which contributes floral, lavender-like notes and is often associated with calming effects. Humulene (0.05–0.2 percent) can add woody, herbal dryness that balances the jammy fruit. Ocimene and terpinolene are typically present only in trace amounts but can sharpen the fruit top-end when expressed.
Total terpene concentration for well-grown indoor flower often ranges from 1.5 to 3.0 percent, with exceptional phenotypes exceeding 3.5 percent. Proper post-harvest handling is critical, as loss rates of 20–35 percent can occur with fast, hot drying. By contrast, slow drying at 60°F and 60 percent RH with ample airflow has been shown to preserve a higher fraction of monoterpenes.
Caryophyllene’s CB2 affinity makes it an interesting contributor to perceived anti-inflammatory effects in anecdotal reports. Myrcene is frequently linked to a relaxed, sedative experience, though human data on entourage interactions remain limited. Limonene’s citrus character may support mood elevation and palatability, making repeated sessions more enjoyable.
For extractors, terpene retention is best in live resin and cold-cured rosin made from fresh frozen material. Hydrocarbon extractions run at low temperatures exhibit more complete terpene spectra, including volatile monoterpenes. This can result in a more faithful translation of Madds Urkle Queen’s grape-berry bouquet into concentrate form.
Experiential Effects and Use Scenarios
Consumers typically report a gentle onset within 2–5 minutes of inhalation, with a clear, happy headspace that gradually settles into a full-body calm. Peak effects arrive around 30–45 minutes and persist for 2–3 hours depending on dose and tolerance. The overall mood is tranquil and unhurried, reflecting the cultivar’s mostly indica heritage.
Physically, users describe heavy eyelids, muscle looseness, and a softening of stress-related tension. Cognitive effects remain present but not overwhelming when doses are moderate. In larger amounts, the strain can become deeply sedating, encouraging couch time or sleep.
This profile suits evening wind-down, movie nights, and post-exercise recovery. Many report improved ease of falling asleep when used 60–90 minutes before bed. Creative sessions can be productive at low doses, where the berry-sweet aroma and mild euphoria maintain engagement without jitter.
Pairing considerations include quiet activities like mellow playlists, light stretches, or a warm bath. For social use, small doses can keep conversation warm and relaxed without heavy intoxication. Food pairings that accentuate berry and cocoa notes—such as dark chocolate or berry compotes—mirror the terpene profile nicely.
Tolerance and individual responses vary, with body weight, prior use, and set-and-setting shaping outcomes. New users should start low and go slow, especially in edible formats where effects can last 4–8 hours. Hydration and a calm environment improve the overall experience and reduce the likelihood of overconsumption discomfort.
Potential Medical Applications
As a mostly indica cultivar with a likely myrcene- and caryophyllene-forward profile, Madds Urkle Queen aligns with use cases targeting sleep support and muscle relaxation. Anecdotally, patients report assistance with sleep onset and maintenance when consumed in the evening. The strain’s calming trajectory can also reduce perceived stress and situational anxiety in low doses.
For pain, THC-dominant chemotypes have demonstrated analgesic potential in observational studies and clinical contexts, including neuropathic pain. Caryophyllene’s interaction with CB2 receptors may contribute to anti-inflammatory effects, though human data are still developing. Users often note relief from tension headaches and muscle soreness after moderate inhalation doses.
Appetite stimulation is a common secondary effect in indica-leaning strains. Patients undergoing appetite challenges may find that small, repeated inhalations before meals encourage hunger without excessive intoxication. This can be particularly useful in palliative settings where caloric intake is a key concern.
Some patients with mood-related symptoms report short-term improvements in calm and outlook, especially when pairing cannabis with supportive routines like mindfulness or gentle movement. Linalool’s presence, even in modest amounts, has been associated with anxiolytic properties in preclinical studies. However, strain-specific responses are individual and require careful self-titration.
None of these observations constitute medical advice, and cannabis interacts with medications and conditions in complex ways. Patients should consult qualified healthcare professionals familiar with cannabinoid therapies. Documenting dose, timing, and outcomes in a simple journal can help identify personal efficacy and minimize side effects.
Cultivation Guide: Indoors, Outdoors, and Greenhouse
Madds Urkle Queen grows predictably indoors, where its compact, indica-forward structure shines. Veg under 18 hours of light with canopy temperatures of 24–26°C and RH at 55–65 percent. In flower, maintain 21–24°C days, 18–21°C nights, and 45–50 percent RH to reduce botrytis risk in dense colas.
Provide 300–500 µmol·m⁻²·s⁻¹ PPFD during early veg, increasing to 600–750 by late veg. In bloom, 700–900 PPFD suits most setups, or up to 1,000 with supplemental CO2 at 900–1,100 ppm. Keep VPD around 0.9–1.1 kPa in veg and 1.2–1.5 kPa in flower for strong transpiration and nutrient flow.
In soil or soilless blends, aim for a root-zone pH of 6.3–6.8; in hydro or coco, target 5.8–6.2. Use a balanced vegetative feed that delivers 120–180 ppm N alongside adequate Ca and Mg. Transition to bloom nutrients at the flip, tapering nitrogen and increasing phosphorus and potassium from weeks 3–7.
Calcium and magnesium demands increase under high-intensity LEDs. Incorporate Cal-Mag supplementation at 100–150 ppm combined, especially in coco systems. Monitor runoff EC to avoid salt accumulation, keeping feed EC around 1.6–2.2 mS·cm⁻¹ depending on stage and plant response.
Training is straightforward: top at the 5th node, then run a screen-of-green to fill a 60×60 cm footprint with two plants. Expect a 1.2–1.6x stretch after the flip, which is easy to contain with one to two toppings and minor supercropping. Defoliate lightly at day 21 and day 42 to open airflow, but avoid stripping too aggressively as indica leaves contribute to carbohydrate reserves.
Flowering time typically runs 56–63 days from the flip for most phenotypes, with some finishing by day 65. Indoor yields of 400–550 g·m⁻² are common with dialed environments, and advanced growers can exceed 600 g·m⁻² using multi-top training and CO2. Outdoor plants in full sun and rich soil often produce 500–800 g per plant, depending on veg duration and water management.
Because colas are dense, integrated pest management and humidity control are essential. Scout weekly for powdery mildew, thrips, and spider mites; employ preventative measures like beneficial mites (Amblyseius swirskii) and foliar inoculants in veg. Avoid oil-based sprays after week two of flower to preserve trichomes and terpenes.
For greenhouse and outdoor grows, site selection and airflow determine success. Position plants to receive consistent morning sun and afternoon breezes, and maintain wide plant spacing to minimize microclimates. If night temperatures fall below 18°C late season, purple expression increases, but protect roots from prolonged cold to maintain metabolic activity.
Watering frequency should follow pot weight and VPD, avoiding chronic saturation. In coco, many growers use 2–4 small irrigations per day in mid-flower to maintain high oxygen at the root zone. In soil, deep, less frequent watering encourages robust root development and reduces fungus gnat pressure.
Phenotype notes: some expressions lean heavily into purple with slightly lower stretch and marginally shorter flower times. Others stay greener, with a touch more vigor and yield but slightly lighter grape notes. Clonal selection based on desired aroma intensity, bud density, and disease resistance is advised for repeat cultivations.
For extraction-focused grows, push PPFD toward the higher end of the recommended range and harvest at optimal trichome maturity to maximize resin returns. Gentle handling during harvest and bucking preserves trichome heads for dry sift and rosin workflows. With correct technique, resin returns of 18–25 percent on fresh-frozen rosin are achievable on terpene-rich, Urkle-forward lines.
Harvest, Drying, and Curing
Optimal harvest windows often appear when 5–15 percent of trichomes have turned amber, with the rest cloudy under 60–100x magnification. Pistils will be largely receded and colored, and calyxes swollen. Harvesting during the dark cycle or right at lights-on can modestly reduce volatile loss.
Dry in a dark room at 60°F and 60 percent RH with gentle airflow for 10–14 days, depending on bud size. Aim for a slow, even dry until small stems snap rather than bend. Rapid drying can reduce terpene content by 20–35 percent compared to controlled slow drying, lowering perceived quality.
Once drying is complete, trim and jar at 62 percent RH using humidity-control packs if needed. Burp jars daily for the first week, then every few days in weeks two and three. A 3–6 week cure consolidates the grape-berry bouquet and smooths the smoke or vapor.
Water activity between 0.55 and 0.65 is a safe target for long-term storage, reducing mold risk while preserving aromatics. Avoid stacking freshly sealed jars, as trapped heat can drive condensation and terpene loss. Label jars with harvest date, phenotype ID, and cure milestones to track performance.
For concentrate production, fresh-frozen harvests cut at peak ripeness and frozen within 30–60 minutes retain the most volatile monoterpenes. Cold-chain integrity from harvest to extraction preserves the signature fruit-forward character. In solventless processes, careful, cold wet-sieving protects trichome head integrity and improves yields.
Quality, Storage, and Shelf Stability
Store cured flower in airtight, opaque containers at 60–65°F and 55–60 percent RH to slow oxidative degradation. Avoid frequent container opening, which exposes terpenes to oxygen and accelerates volatilization. Under proper storage, high-terpene flower retains better sensory quality for 3–6 months, with gradual decline thereafter.
Heat and light are the largest enemies of shelf stability. Exposure to direct sunlight can drive rapid terpene loss and THCa decarboxylation, flattening aroma and potency. Keeping products in a cool, dark cupboard or dedicated storage box maintains quality longer.
For long-term preservation, refrigeration is acceptable if humidity is tightly controlled and containers are fully sealed to prevent moisture cycling. Freezing is best reserved for material destined for extraction, as freeze-thaw cycles can cause trichome brittleness and handling losses. If freezing flower for later smoking, vacuum sealing with humidity buffers reduces damage, though some aroma loss is likely.
Consumers can self-assess freshness by observing scent intensity, bud springiness, and trichome sheen. Dull, hay-like aroma, crumbly texture, and ambered trichomes without stickiness suggest aged material. Madds Urkle Queen’s grape-berry signature is a sensitive indicator of freshness, fading noticeably when storage conditions are suboptimal.
