Written by Ad OpsOrigins and Breeding History
Metal Dragon is a mostly sativa cannabis cultivar developed by SnowHigh Seeds, a breeder known for collecting and working rare landraces and long-flowering tropical sativas. SnowHigh’s catalog often emphasizes vigor, resin production, and high-ceiling head effects, and Metal Dragon fits squarely into that ethos. The strain’s name evokes SnowHigh’s famed “dragon” projects and metallic, incisive aromas that many growers report from its flowers.
The specific parental cross for Metal Dragon has not been publicly disclosed by the breeder, which is common with small-batch, connoisseur releases. In community reports and archived seed lists, Metal Dragon is frequently grouped with SnowHigh’s sativa-forward projects tracing to Central and South American and Southeast Asian stock. That context aligns with its growth profile, long flowering window, and terpinolene-heavy bouquet.
Because the formal pedigree remains proprietary, third-party lineage databases sometimes omit or generalize its ancestry. It is not unusual to see placeholder entries like “Unknown Strain” in genealogy repositories when breeders keep genetics in-house. SeedFinder and similar databases specifically show many genealogies with unknown or partially identified parents, a reminder that not all boutique lines are fully documented in public records.
Genetic Lineage and Heritage
While official parentage is undisclosed, Metal Dragon’s morphology and effects point to a strong tropical sativa heritage. Narrow leaflets, long internodes, and a pronounced flowering stretch are classic indicators of Thai, Colombian, or Mexican influences. The uplifted, clearheaded arc and the terpinolene-forward nose similarly suggest Southeast Asian and Haze-family inputs.
SnowHigh Seeds has long curated landrace and heirloom material from regions like Oaxaca, Colombia, Panama, and Thailand. Many of their sativa releases weave these lines together to preserve vigor while taming extreme flowering times. Metal Dragon likely follows that template, producing a more manageable but still distinctly sativa expression.
The lack of a publicly declared cross means it is sometimes grouped in lineage charts under generic or unknown ancestry. Genealogy tools often include “Unknown Strain” placeholders when breeder-supplied details are partial or private. That is a structural limitation of open databases rather than a reflection on the strain’s quality or consistency.
In practical terms, the heritage is best read from its measurable traits. Expect a sativa-dominant ratio by growth behavior—roughly 70–85% sativa in phenotype expression, based on internode length, leaf morphology, and flowering duration. That aligns well with growers’ reports of long, speared colas and a clean, soaring effect profile.
Visual Appearance and Plant Morphology
Metal Dragon presents as a tall, elegant sativa with narrow, serrated fan leaves and elongated petioles. Internodal spacing tends to be wider than average, which improves airflow but requires early training indoors. A single plant can easily double in height after the light flip, and a 1.5–2.5x stretch is common when grown under high-intensity LEDs.
Flower morphology is spear-like, building into long colas composed of stacked calyxes rather than dense, golf-ball clusters. Calyx-to-leaf ratio is typically favorable, making for easier trimming and better bag appeal. Mature flowers often show lime-to-forest greens with flares of rust-to-copper pistils and a heavy dusting of translucent trichomes.
Under cooler night temperatures in late bloom, some phenotypes may express faint lavender or burgundy hues along sugar leaves. Trichome coverage is robust for a sativa, with visible stalked heads that glint under light. Resin density is high enough to make the cultivar appealing to extractors despite its airy, sativa-style calyx stacking.
Stems are flexible yet strong, especially if silica is provided during veg. This flexibility helps the plant tolerate low-stress training and scrogging without cracking. Still, trellising support is recommended to prevent cola flop during the final three weeks of bloom.
Aroma Profile
Aromatically, Metal Dragon balances bright citrus-tropical lift with a curious metallic tang that inspires its name. The top notes often read as lime zest, green mango, or sweet tangerine, followed by coniferous pine. A crisp, ozone-like coolness can appear on stem rub and during late bloom, hinting at aldehydes and terpenes like terpinolene.
Mid-layer aromas develop as spice and herb, sometimes peppery with a faint basilic or thyme-like edge. Subtle sweetness emerges upon cure, shifting the bouquet toward candied citrus peel and resin. In well-cured samples, the “metallic” note recedes into a pleasant mineral cleanliness rather than an overt sharpness.
Aroma intensity is above average, frequently 7–9/10 depending on phenotype and cure quality. Growers should plan for robust carbon filtration indoors, particularly in the final four weeks of flower. In jars, the profile blooms within 10–14 days of a stable cure and tends to keep evolving for four to six weeks.
Flavor Profile
The flavor mirrors the nose with a zesty front end of lime, sweet orange, and underripe mango. Piney resin and white pepper arrive mid-palate, bringing a clean bitterness that enhances the citrus. The “metallic” character translates as mineral freshness rather than tinny harshness when properly flushed and cured.
On exhale, a cool herbal lift lightens the finish, leaving a lingering citrus-resin aftertaste. The mouthfeel is medium-bodied, with a slightly dry, sparkling sensation that’s common in terpinolene-forward sativas. Vaporization often emphasizes the tropical-citrus registers and reduces the pepper bite.
Taste clarity notably improves with a slow dry and 58–62% relative humidity cure. In blind tasting sessions, experienced consumers frequently peg it as “Haze-adjacent” but cleaner and less incense-heavy. Those sensitive to peppery edges may prefer lower-temperature vaporizer settings around 180–190°C to accentuate citrus over spice.
Cannabinoid Profile and Potency
Because Metal Dragon’s breeder has not published official lab averages for this specific strain, potency ranges are inferred from similar SnowHigh sativa projects and community test results. In those contexts, total THC commonly falls between 18–26%, with potent phenotypes pressing into the upper 20s under optimized lighting and nutrition. CBD is usually minimal, frequently under 1% and often below 0.2% in THC-dominant expressions.
Minor cannabinoids are present in trace-to-moderate amounts and contribute meaningfully to the effect arc. CBG often appears between 0.3–1.2%, and CBC between 0.2–0.6% in comparable sativa-dominant cultivars. Total cannabinoid content (sum of THC, CBD, CBG, CBC, and others) often reaches 20–29% in dialed-in indoor runs.
Potency is strongly influenced by harvest timing and environmental control. A later harvest with 5–15% amber trichomes can push perceived body weight and sedation, while an earlier cloudy window maximizes perceived vigor and mental clarity. For consumers, the subjective intensity often feels like a “high-ceiling” sativa that remains clear until larger doses tip into racy territory.
Edible infusions preserve the mental lift but add length, with 4–6 hour durations common at moderate doses. For inhaled routes, onset typically occurs within 2–5 minutes, peaking around the 30–60 minute mark. Duration after inhalation is usually 2–3 hours, with a clean taper if dosage is moderate.
Terpene Profile and Minor Volatiles
Metal Dragon presents a terpene profile typical of tropical sativas, with terpinolene frequently leading. In analogous sativa-dominant lab results, terpinolene often ranges from 0.5–1.5% by dry weight, followed by myrcene around 0.3–0.8%. Ocimene, limonene, and beta-caryophyllene generally stack next, commonly in the 0.2–0.6% range.
Humulene, linalool, and alpha-pinene appear as supporting actors, usually between 0.05–0.3% depending on phenotype and environment. The metallic-mineral nuance is likely a composite of terpinolene’s crispness, pinene’s coniferous lift, and oxidative products like caryophyllene oxide formed during late flower and storage. Proper cure and storage at 58–62% RH reduces oxidative harshness while preserving bright top notes.
Terpene expression is highly sensitive to light intensity, temperature swings, and harvest timing. Cooler night temps during late bloom can preserve monoterpenes, while excess heat above 30°C may volatilize them prematurely. Nutrient balance also matters: overfeeding nitrogen late in flower can mute terpenes and dull the finish.
For extraction, fresh-frozen material captures monoterpenes like terpinolene and ocimene more effectively than dried input. Producers targeting live resin or sauce often harvest at peak terpene production before prolonged oxidation. That approach aligns with industry best practices highlighted by concentrate-focused guides that emphasize optimizing harvest to maximize both cannabinoids and terpenes for closed-loop BHO work.
Experiential Effects
The effect profile is resolutely sativa-forward: alert, buoyant, and sensory-enhancing. Within minutes of inhalation, many users report a mental lift, improved task engagement, and a light, kinetic energy. Music, color, and pattern recognition can feel more vivid, consistent with terpinolene- and pinene-rich profiles.
At moderate doses, the headspace stays organized and clear, with a gentle euphoria that suits daytime use. At higher doses, some individuals experience a racy edge—faster heart rate, a flutter of anxiousness, or a ‘too-much-caffeine’ sensation. Those effects correlate with low CBD content and monoterpene dominance.
The body feel is present but restrained, arriving as loosened shoulders and subtle eye pressure rather than heavy sedation. A small subset of phenotypes leans slightly more hybrid, with a mellowing body effect later in the arc. As tolerance builds, the same dose may feel less pushy and more quietly focused.
Side effects are the usual suspects: dry mouth and eyes are common, and transient tachycardia can occur in sensitive users. Hydration and a paced dosing strategy mitigate most issues. For newcomers, starting with a single, shallow inhalation and waiting 10 minutes before re-dosing is prudent.
Potential Medical Applications
Although Metal Dragon is primarily positioned as a recreational sativa, its profile suggests several potential therapeutic niches. The uplifted, energizing arc can be useful for daytime fatigue and situational low mood. Limonene and terpinolene have been studied for mood-elevating and alertness-supportive properties in preclinical models, which aligns with user reports.
Beta-caryophyllene, often present at 0.2–0.4%, is a selective CB2 agonist with evidence for anti-inflammatory and analgesic effects. While the caryophyllene levels here are modest, the entourage with humulene and myrcene may offer a cumulative benefit for mild inflammatory discomfort. People with neuropathic pain sometimes prefer such sativas for functional relief without heavy sedation.
Metal Dragon’s clarity and focus can be supportive for attention-related challenges in low-to-moderate doses. Users often describe improved task initiation and a sense of flow, though overstimulation is possible at higher intakes. For anxiety-prone individuals, pairing with a CBD-dominant product or choosing a lower dose can smooth the ride.
As with all cannabis-based interventions, individual responses vary. Prospective medical users should consult healthcare providers, especially when using cannabis alongside other medications. Keeping a journal of dose, timing, and outcomes can help identify personal therapeutic windows and minimize side effects.
Comprehensive Cultivation Guide
Metal Dragon is manageable indoors with planning and thrives outdoors in warm, temperate-to-tropical climates. Indoors, allocate vertical space or deploy aggressive training early in veg. Expect a 1.5–2.5x stretch and plan trellis support to manage the long colas that form in late flower.
Germination is straightforward with fresh seed and standard protocols. Soak for 12–18 hours, then place in a lightly moistened starter cube at 24–26°C with high humidity around 70–80%. Most quality seeds will pop within 24–72 hours, and gentle bottom heat improves uniformity.
Vegetative growth prefers moderate nitrogen and steady calcium and magnesium. In coco, target pH 5.8–6.2 with EC 1.2–1.8 mS/cm; in living soil, keep irrigation water near pH 6.3–6.8. Aim for 400–600 µmol·m⁻²·s⁻¹ PPFD in veg with 18/6 or 20/4 lighting and maintain RH at 55–70% for rapid leaf expansion.
Transition to flower with a full canopy and strong branch structure. In bloom, raise PPFD to 800–1000 µmol·m⁻²·s⁻¹ under CO₂ at 900–1200 ppm if available; without supplemental CO₂, 700–900 PPFD is a safer ceiling. Day temperatures of 24–29°C with night temps 18–22°C help preserve terpenes and limit stretch.
Humidity control is critical during mid-to-late bloom. Keep RH around 45–55% during weeks 3–6 of flower and 40–48% in the final two weeks. Target a VPD of 1.1–1.4 kPa in mid bloom and 1.2–1.6 kPa late, balancing resin production with mold prevention.
Nutritionally, reduce nitrogen after week 4 of flower to avoid grassy tastes and encourage terpene expression. Increase phosphorus and potassium gradually, aiming for a bloom ratio that shifts from N-heavy early to K-forward late (e.g., moving toward a 1–2–3 style emphasis by week 6). Maintain a Ca:Mg ratio near 3:1 and supplement 50–100 ppm silica during veg for stem strength.
Training techniques like topping, low-stress training, and SCROG are highly effective. Top once or twice in veg to spread apical dominance across multiple arms, then weave into a net to fill a rectangular footprint. Avoid heavy defoliation late in flower; instead, practice selective leaf removal for airflow during weeks 3–5.
Watering strategy should encourage rhythmic dry-backs without stress. In coco, frequent, smaller irrigations to 10–20% runoff maintain stable EC and oxygenation. In soil, allow the top inch to dry while keeping the root zone evenly moist; use pot weight as a reliable guide.
Flowering time is typically 70–90 days from flip depending on phenotype and environment. Earlier phenos can finish near day 70 with a brisk, citrus-forward profile, while late phenos at day 84–90 deepen in spice and resin weight. Outdoors, harvest generally lands from mid- to late-October in temperate latitudes, with earlier finishes in hotter, high-sun regions.
Pest and pathogen management should be proactive. Powdery mildew pressure increases in dense sativa canopies; maintain airflow at 0.5–1.0 m/s across the canopy and avoid big RH swings. Biological controls (e.g., Bacillus subtilis for foliar disease, predatory mites for spider mites) and sulfur-only applications in early veg can reduce outbreaks.
Yield potential is strong for a sativa-dominant, with indoor SCROG runs reaching 450–650 g/m² under 600–1000W class LEDs. Expert growers with long veg and CO₂ can exceed 700 g/m² by maximizing horizontal canopy. Outdoor plants, if started early and trained wide, can deliver 700–1200 g per plant in high-sun, low-humidity locations.
Harvest timing should be guided by trichome maturation and desired effect. For a bright, energetic profile, harvest when most trichomes are cloudy with minimal amber (0–5%). For a rounder, more relaxing finish, wait for 5–15% amber across calyces while avoiding overripe, oxidized heads.
Drying and curing protocols have outsized impact on flavor fidelity. A slow dry of 10–14 days around 15–18°C and 58–62% RH preserves monoterpenes like terpinolene and ocimene. Cure in airtight containers burped as needed for four weeks to stabilize water activity and mature the bouquet.
For extractors, fresh-frozen harvest captures the strain’s high-volatility monoterpenes best. Closed-loop BHO or hydrocarbon extraction with subzero solvent temperatures retains the citrus-pine top end. Industry guidance emphasizes harvesting at peak terpene production to optimize both terpene and cannabinoid yields for concentrates, a practice echoed in expert buyer guides for Northern California concentrate production.
Market Context, Extracts, and Consumer Tips
Sativa-forward cultivars with crisp, terpene-rich profiles have been gaining market traction across legal states. Lifestyle brands have leaned into this momentum, with high-visibility labels expanding regionally and emphasizing flavor-driven experiences. High-energy, party-forward positioning has become common as brands ride the wave of citrus- and candy-forward terpene demand.
For concentrates, producers increasingly optimize harvest windows and post-processing to maximize both cannabinoids and terpenes. Concentrate buyer guides consistently stress that each strain should be harvested at its optimal moment for closed-loop BHO to capture peak chemistry. Metal Dragon’s terpinolene-leading profile makes it a strong candidate for live resin, sauce, and high-terp fractionation when handled at cold temperatures.
Consumers seeking the best expression should look for clear certificates of analysis (COAs) with terpene data, not just THC percentage. For this profile, terpinolene above ~0.5% with supporting limonene, ocimene, and pinene usually signals a bright, clean experience. If you prefer less raciness, select phenotypes with slightly higher beta-caryophyllene and myrcene, and consider vaping at lower temperatures.
In flower form, inspect for long, speared colas and a sparkling trichome sheath. Aroma should bloom as citrus-pine with a cool, mineral lift rather than a harsh, chemical bite. Properly cured samples should feel springy, not brittle, and deliver a smooth, zest-forward finish without grassy undertones.
