Maple Leaf x Black Domina is a resin-heavy indica bred by Expert Seeds that blends two stalwart Afghan-leaning lines into a compact, fast-finishing powerhouse. Its heritage leans decisively indica, and it shows in the short internodes, broad leaves, and heavy, calming body effects. Growers value its reliable structure, vigorous early growth, and generous resin output that makes it a natural fit for hash and rosin.
On the consumer side, this cultivar offers dense, sticky buds with a sweet-citrus top note layered over earthy, hash-like depths. Reports commonly describe a quick onset of relaxation that deepens into a tranquil, couch-lock finish at higher doses. With contemporary phenotype selection and careful dialing-in, batches can test in the upper-teen to low-20 percent THC range, offering potent, consistent effects.
Because both parents are staples in indica breeding, Maple Leaf x Black Domina tends to be forgiving for newer growers yet rewarding for experts. Its quick flower time makes it suitable for short-season outdoor sites and for indoor growers aiming to increase annual turnarounds. The cultivar pairs well with evening routines, recovery days, and flavor seekers who appreciate classic Afghan tones brightened by fruit and citrus.
History and Breeding Origins
Expert Seeds developed Maple Leaf x Black Domina to capture the unmistakable Afghan hash-plant character while improving vigor, flavor complexity, and speed. Maple Leaf Indica is widely regarded as a pure or near-pure Afghan type, prized for its sweet, syrupy resin and old-world hash notes. Black Domina, by contrast, is a multi-Afghan hybrid known for its ultra-dark foliage, compact stature, and hammering body stone.
By combining these two, Expert Seeds targeted uniform indica expression with modern reliability in feminized form. The goals were clear: fast indoor flowering, strong apical dominance for SOG, thick trichome coverage for extractors, and a terpene profile that balances sweet fruit and citrus above earthy base notes. The result is a line that meets commercial deadlines while retaining connoisseur charm.
Live market info around indica fast versions aligns with the project’s emphasis on speed and potency. Vendors note that fast-flowering strains in this flavor space can reach up to 23 percent THC and finish swiftly, with buds that are thick, sticky, and notably fragrant with sweet fruit and citrus. The Maple Leaf feminized heritage is also associated with a blissful onset that transitions into body-calming couch-lock, a signature effect this cross preserves.
Genetic Lineage and Inheritance
Maple Leaf Indica contributes a deep Afghan backbone, often translating into high myrcene expression, stout stature, and early finishing. This parent is renowned for heavy resin glands and a sugary, almost maple-like sweetness layered atop classic hash aromas. These traits are dominant and regularly surface in filial generations, including robust trichome density and a soothing somatic effect profile.
Black Domina adds a complex Afghan hybridization that further tightens internodal spacing and increases bud density. It is known for nocturnal potency, near-black foliage in cooler environments, and a peppery-spicy caryophyllene component that can bolster anti-inflammatory potential. Its historic reputation for fast and uniform flowering complements Maple Leaf’s early finish.
In combination, the cross typically expresses 80–100 percent indica morphology with minimal stretch and a fast bloom window. Expect strong apical dominance, making the plant ideal for Sea of Green or compact SCROG setups. The terpene inheritance often centers on myrcene, limonene, and caryophyllene, creating a sweet-citrus over hash-and-spice stack that is both familiar and modern.
Physical Appearance and Plant Morphology
Plants tend to be short to medium in height, commonly finishing at 70–110 cm indoors with minimal stretch after flip. The canopy fills with broad, dark, glossy fan leaves that signal robust chlorophyll content and indica vigor. Internodal spacing is tight, typically 2–5 cm under high-intensity light, promoting dense cola formation.
Buds are compact, golf-ball to soda-can sized, and pack on weight quickly from week 4 onward. Calyxes swell in later bloom, and bract-to-leaf ratios are favorable, which simplifies trim work and improves bag appeal. Trichome coverage is copious, with visible heads clouding out by maturity and giving buds a frosty, sticky hand-feel.
Coloration can darken toward late flower, especially under night temperatures 3–5°C lower than day. Anthocyanin expression ranges from subtle olive-bronze to deep forest green, with some phenotypes showing near-black sugar leaves reminiscent of Black Domina. Pistils usually start pale cream to light tangerine, ripening into deeper amber hues by harvest.
Root systems are vigorous and fibrous, rewarding slightly larger containers than the plant’s height might suggest. In coco or well-aerated soil, roots rapidly colonize the media, supporting heavy feeding during weeks 3–6 of flowering. Adequate container volume—11–19 liters indoors—helps maximize yield per plant while maintaining manageable size.
Aroma and Bouquet
The dominant aromatic impression is a clean, dessert-like sweetness layered with zesty citrus top notes. Underneath sits a classic Afghan hash base, earthy and slightly woody, with suggestions of incense and cured spices. Myrcene contributes ripe fruit tones, while limonene brightens the nose with lemon-lime and sweet orange fragments.
Freshly broken flowers often release a burst of candied citrus, reminiscent of sugared peel or marmalade. As buds breathe, deeper resin and sandalwood nuances emerge, echoing old-world charas and temple ball traditions. Caryophyllene adds a warm pepper tickle that becomes more apparent in the grinder.
Growers report that the aroma intensifies rapidly from week 5 onward, with resin glands swelling and terpenes concentrating. Carbon filtration is recommended indoors, as the bouquet can become room-filling by late bloom. In jars, the cured nose evolves toward a honeyed, slightly floral sweetness balanced by earthy hash and citrus zest.
Flavor Profile and Consumption Notes
On inhalation, Maple Leaf x Black Domina typically delivers a sweet, velvety mouthfeel that evokes candied fruit. A citrus splash follows—lemon drop, orange oil, and a hint of lime—before settling into Afghan earth and light cedar. The exhale is smooth when properly flushed and cured, with a lingering sugar-and-peel aftertaste.
Combustion produces thick, fragrant smoke, while vaporization at 175–195°C highlights limonene brightness and floral linalool traces. At slightly higher vapor temps (200–205°C), deeper hash, wood, and pepper notes surface as caryophyllene volatilizes more fully. Concentrates from this cultivar are often terp-rich, with rosin yields that can exceed 18–22 percent from premium, fresh-cured material.
Pairing suggestions include citrus-forward teas, dark chocolate, or lightly spiced desserts to mirror and amplify the profile. For glass cleaning and device maintenance, note the resin can be exceptionally sticky; regular upkeep preserves flavor clarity. A 2–3 week slow cure at 60–62 percent relative humidity typically unlocks the most cohesive flavor stack.
Cannabinoid Content and Potency
Potency in this lineage commonly falls in the 18–23 percent THC range when grown and cured under optimal conditions. Fast-flowering versions tied to similar indica lines have been listed by vendors as capable of reaching about 23 percent THC, and Maple Leaf-family descriptions often emphasize a heavy body-calming effect and couch-lock. CBD is usually low, often below 0.5 percent in standard phenotypes, making the chemotype THC-dominant.
Minor cannabinoids like CBG and CBC appear in trace amounts, with CBG commonly around 0.2–0.6 percent in well-developed flowers. Total cannabinoids can exceed 20 percent when THC and minors are combined, particularly in phenotypes with exceptional trichome density. For users sensitive to THC, titrating dose remains important due to the cultivar’s sedative trajectory.
From a pharmacological perspective, the synergy between high THC and abundant myrcene and caryophyllene may enhance perceived sedation and physical relief. Myrcene has been associated in observational data with heavier body sensations, while caryophyllene’s activity at CB2 can complement anti-inflammatory effects. As always, lab verification is recommended, since chemotypes can vary by environment, cut, and cultivation method.
Terpene Profile and Chemistry
The terpene spectrum is typically led by beta-myrcene, which can represent 0.4–1.4 percent by dry weight in myrcene-dominant indica flowers. Limonene is a primary secondary terpene, often contributing 0.2–0.7 percent by weight and providing the bright citrus lift. Beta-caryophyllene commonly measures 0.2–0.6 percent, lending pepper, warmth, and potential CB2 engagement.
Supporting terpenes frequently include humulene, linalool, and ocimene in the 0.05–0.3 percent range each, depending on phenotype and cure. Humulene layers in subtle herb and wood, linalool adds a mild floral-lavender edge, and ocimene can impart a sweet, green fruit tone. Terpinolene is usually minor or trace but may flicker in select plants with fresh, pine-adjacent sparkle.
Total terpene content for this cultivar often sits in the 1.5–3.0 percent range in well-grown indoor flowers. High-PPFD environments with proper nutrition and late-stage stress minimization tend to maximize terpene retention. Post-harvest handling—cool, dark drying at 18–20°C and 55–62 percent RH—can preserve 15–30 percent more monoterpenes compared to warmer, faster dries, based on general craft cannabis drying data.
Experiential Effects and Use Cases
The subjective effect commonly begins with a soft, blissful wash that loosens muscular tension within 10–15 minutes. As onset deepens, a mellow euphoria gives way to body heaviness and calm focus on tactile comfort rather than mental stimulation. At moderate to high doses, many users report a classic couch-lock that matches Maple Leaf heritage notes of a heavy body-calming effect.
Sedation intensifies predictably with dose escalation, making the strain well-suited for evening wind-downs and pre-sleep routines. Appetite stimulation is common, and time dilation often accompanies the tranquil mood shift. Social use can be pleasant in relaxed settings, though the cultivar is generally more contemplative and restorative than chatty.
For creative tasks, microdosing can preserve clarity while softening background stress and physical discomfort. Athletes and active users sometimes employ the strain post-workout for relaxation and sleep support. Newer consumers should start low, as the transition from relaxed to fully sedated can happen quickly with high-THC, myrcene-forward indicas.
Potential Medical Uses and Considerations
Users and caregivers often target this cultivar for sleep onset and sleep maintenance challenges. The combination of THC, myrcene, and caryophyllene has anecdotal support for reducing perceived pain and facilitating relaxation, which can indirectly improve sleep quality. Small-scale observational data across indica cohorts suggest benefits for insomnia, though controlled trials remain limited.
Chronic pain, muscle spasms, and post-activity soreness are common use cases reported in community data. The warming, numbing body sensation can ease discomfort without excessive head fog at modest doses. Appetite stimulation may assist users facing diminished hunger, such as those in recovery or dealing with treatment-related anorexia.
Caution is warranted for individuals prone to anxiety with strong THC, though many find the calming body effect counters racy edges. Daytime use can impair productivity due to sedation, and machinery operation should be avoided. As always, medical use should be discussed with a healthcare professional, especially when combining cannabis with other sedatives or medications metabolized by CYP450 enzymes.
Comprehensive Cultivation Guide
Growth pattern and timing: Maple Leaf x Black Domina typically completes indoor flowering in 7–8 weeks under 12/12, with some fast-leaning phenotypes finishing in as little as 45–50 days. Outdoors in temperate zones, harvest usually lands from late September to early October in the Northern Hemisphere. Plants stretch minimally after flip, commonly 25–50 percent, making canopy planning straightforward.
Yields: Under optimized indoor conditions, expect 450–550 g per square meter with 9–12 plants in 11-liter containers or 16–25 plants in SOG. Well-grown outdoor plants can produce 600–900 g per plant in 30–50 liter containers or in-ground beds, contingent on season length and sun exposure. CO2 supplementation to 1,000–1,200 ppm can boost yields by 10–20 percent if PPFD and nutrition are properly matched.
Environment: Target day temperatures of 24–26°C in flower and 18–21°C at night, with 45–55 percent RH; reduce to 40–45 percent in the final two weeks. Maintain VPD around 1.0–1.2 kPa during mid-to-late bloom to balance transpiration and terpene retention. Provide 800–1,000 μmol m−2 s−1 PPFD for flower; more is possible with CO2 and impeccable fertigation.
Medium and nutrition: The cultivar thrives in aerated soil, coco, or hydro, with a slight preference for coco or light-mix soil for rapid root development. Maintain pH at 6.3–6.8 in soil and 5.8–6.1 in coco or hydro. Feed EC ranges of 1.2–1.5 in mid-veg and 1.6–1.9 in peak flower are typical; emphasize phosphorus and potassium from weeks 3–6 of bloom.
Calcium and magnesium: Afghan-leaning plants often appreciate steady Ca and Mg, especially under LED lighting. A Ca:Mg ratio around 3:1 generally prevents deficiency; consider 100–130 ppm Ca and 30–50 ppm Mg in solution during peak uptake. Watch for interveinal chlorosis under high light as a sign to adjust Mg.
Training: The tight node spacing suits Sea of Green with minimal veg, topping once at the 4th–5th node if needed. For larger plants, a single topping plus light low-stress training can open the canopy and expose bud sites. Screen of Green also works well; aim for an even table to keep cola heights uniform and limit larf.
Irrigation: In coco, fertigate to 10–20 percent runoff 1–3 times daily depending on pot size and root mass. In soil, water deeply then allow substantial dry-back to promote oxygenation. Avoid over-saturation during late flower as dense buds are susceptible to microclimate humidity spikes.
Pest and disease management: The compact structure demands strong airflow. Use oscillating fans to disrupt stagnant pockets, and keep canopy density in check with selective defoliation around weeks 3–4 of flower. The Afghan heritage offers decent mold resilience, but dense colas still require vigilance against botrytis in RH above 55 percent.
Defoliation and pruning: Remove lower interior growth pre-flip to focus resources on top sites. Light defoliation mid-bloom improves airflow and light penetration without stressing the plant. Avoid aggressive leaf stripping late in flower to prevent terpene loss and delayed ripening.
Guerrilla and short-season growing: The fast finish and compact size are ideal for stealth or off-grid plots. Choose sunny, well-drained locations, camo the silhouette with native vegetation, and consider water-retentive polymers or mulches to reduce site visits. Slug barriers, light deer fencing, and time-release nutrition can improve success rates and minimize attention.
Harvest markers: Trichomes typically turn cloudy by week 7, with 10–15 percent amber from days 52–60 under optimal conditions. For a heavier sedative effect, allow 20–25 percent amber, monitoring daily to avoid over-ripening. Pistil color alone is insufficient; rely on trichome heads viewed at 60–100x magnification.
Drying and curing: Dry at 18–20°C and 50–55 percent RH for 9–12 days to protect monoterpenes. Cure at 60–62 percent RH for 2–4 weeks, burping jars as needed to maintain fresh, zesty citrus over the Afghan base. Proper curing can preserve 70 percent or more of the perceived aroma intensity compared to rushed dries.
Expected performance summary: With standard feminized seeds—which many modern breeders claim exceed 99 percent female expression—growers should see consistent indica morphology and reliable finish times. The line’s vigor and resin density make it a strong candidate for solventless extraction, with rosin yields that can exceed 18–22 percent from top-tier flowers. Uniform canopies and careful climate control translate directly into higher yields and terpene retention.
Phenotype Variation, Selection, and Breeding Potential
Most packs exhibit low-to-moderate phenotypic variance, usually revolving around the ratio of sweet citrus to hash-spice in the terpene profile. Some plants lead with bright limonene and candied fruit, while others are more earthy and peppered, reflecting Black Domina’s caryophyllene push. Bud density is consistently high across phenotypes, and trim leaf volume is manageable.
When selecting keepers, prioritize resin head size and stalk robustness for solventless work. Under a loupe, look for large, bulbous heads with strong, flexible stalks that resist shearing during hash washing. Flavor coherence—sweet citrus overlay integrated with wood-spice base—often predicts standout cured quality.
For breeding projects, Maple Leaf x Black Domina imparts early flowering, compact stature, and heavy resin reliably. Crossing to fruit-forward sativas can create balanced hybrids that retain speed while opening canopy structure. In backcrosses or line-breeding, locking in the citrus-forward myrcene-limonene expression can yield a signature nose with classic Afghan weight.
Harvest, Drying, Curing, and Storage
Pre-harvest, reduce nitrogen in weeks 6–8 and keep feeds clean to promote smooth combustion and clear flavor. Flushing in soilless systems for 7–10 days or tapering inputs in living soil can both achieve a clean finish. Aim for a slow, controlled fade rather than a rapid crash, which can stress the plant and dull terpenes.
During harvest, handle colas gently, as trichome heads are abundant and can be knocked off with rough contact. Whole-plant hangs slow the dry and help maintain terpene integrity; large branches work well too if RH is stable. Avoid drying above 22°C or below 45 percent RH, conditions that can volatilize monoterpenes or overdry the exterior while trapping moisture inside.
Post-dry, trim carefully to preserve sugar leaves that are saturated with trichomes, then jar at 60–62 percent RH. Burp jars daily for the first week, then every 2–3 days in week two, and weekly thereafter as the cure stabilizes. Properly cured flowers often peak in aroma between weeks 3 and 8 of cure, with sweet fruit and citrus brightening as chlorophyll notes dissipate.
For long-term storage, use airtight glass with minimal headspace, stored in a dark space at 15–18°C. Consider adding humidity control packs to stabilize at 58–62 percent RH. Vacuum-sealed mason jar systems or stainless containers can further extend freshness for 6–12 months when kept cool and dark.
Availability, Seed Types, and Buying Tips
Expert Seeds offers Maple Leaf x Black Domina in feminized formats aimed at consistent female expression and simplified garden planning. Growers may also encounter fast or early versions in the broader indica market, where vendors highlight super-quick flowering and potency reaching up to approximately 23 percent THC. Always verify that the listing matches the intended breeder and cross to avoid mix-ups.
When purchasing, look for recent production batches, intact breeder seals, and storage with climate control. Seeds kept at 6–8°C and 20–30 percent RH maintain viability far longer than those stored warm, and reputable retailers tend to advertise their handling standards. Germination rates for quality feminized seeds commonly exceed 90 percent under optimal conditions.
For phenotype hunts, consider larger packs to improve odds of finding a citrus-forward keeper with exceptional resin. If growing in a limited plant-count environment, select vendors that provide detailed lineage notes and grow data. Cross-reference community grow logs to confirm performance in your climate and setup.
