Overview

Mountain Deux is a mostly indica cannabis cultivar bred by Mosca Seeds, a breeder recognized for robust, resin-forward genetics. The name playfully nods to effervescence and elevation, and the cultivar tends to deliver a calm, body-centered experience with crisp, bright top notes. According to the context provided, its heritage leans predominantly indica, which aligns with Mosca’s catalog strengths and the strain’s compact structure and fast finish.

While Mountain Deux has not been publicized with a fully disclosed parentage, it fits into the contemporary category of indica-leaning hybrids that combine dense flowers, high trichome output, and approachable citrus-forward aromatics. In practice, that usually translates to a flowering time near the 8–9 week mark, a medium height profile indoors, and an output that satisfies both home cultivators and commercial rooms. Growers can expect a balanced profile that is relaxing without being immobilizing at moderate doses.

From a consumer standpoint, Mountain Deux tends to be characterized by clean flavors, a weighted but clearheaded body effect, and approachable potency. In most markets, indica-dominant hybrids regularly test in the 18–24% THC range, and Mountain Deux is expected to land in the same window depending on cultivation variables. As always, lab results vary by phenotype, environment, and post-harvest handling, but this cultivar is built for consistency and resin quality—both hallmarks of Mosca Seeds’ breeding program.

History and Breeding Background

Mosca Seeds—often referred to simply as Mosca—has been active since the mid-2000s and is known for pairing time-tested building blocks with modern flavor-forward lines. Their work frequently emphasizes structure, finish, and high resin production, delivering cultivars that perform for both extract and flower markets. Mountain Deux appears within this breeding context as a mostly indica offering with attention to quick turnaround and dense, market-ready buds.

The specific year of release and parent lines for Mountain Deux have not been formally published, which is common for boutique offerings and breeder-protected IP. However, Mosca’s portfolio historically leans on indica-dominant stock and outcrosses that lock in vigor and uniformity. The result is a strain that behaves predictably under a range of conditions and finishes on a schedule friendly to both indoor and short-season outdoor growers.

Naming conventions in modern cannabis often hint at aroma or generational iterations, and “Deux” makes a wry reference to both a second take and a fizzy, citrus-forward profile. Many growers report lemon-lime, sweet citrus, and evergreen notes, which suggests a terpene backbone populated by limonene and pinene with a grounding base of myrcene or caryophyllene. That sensory footprint mirrors consumer preferences in recent years, where bright, uplifting aromatics are paired with a comfortable indica body feel.

In terms of market position, Mountain Deux fits a practical niche: reliable yields, approachable potency, and flavors that are easy for new consumers to enjoy. As indica-leaning hybrids have dominated North American flower shelves for the last decade, cultivars with an 8–9 week finish and 450–600 g/m² potential indoors tend to see steady demand. Mountain Deux was bred to meet that demand without sacrificing character or bag appeal.

Genetic Lineage and Heritage

The provided context confirms that Mountain Deux is mostly indica and bred by Mosca Seeds. While the breeder has not posted a public, definitive parentage for this cultivar, the plant’s structure and finish timeline align with Afghani/Kush-influenced stock. In practice, indica-leaning hybrids like this tend to express shorter internodes, broad leaflets, rapid vegetative growth, and a compact final form suitable for high-density canopies.

Breeders often stabilize indica traits by using proven lines known for resin density, hardiness, and wariness of mildew—then layering in modern flavor traits via targeted outcrosses. In many Mosca releases, that means capturing citrus, berry, or sweet confectionary notes without losing yield or speed. Mountain Deux fits that template, as evidenced by grower observations of dense, frost-heavy flowers with a bright top-end aroma.

Because the exact lineage is not disclosed, it is most accurate to frame Mountain Deux as a contemporary indica-dominant hybrid with a citrus-forward chemotype. In cannabinoid terms, indica-leaning hybrids frequently test at 18–24% THC with minor cannabinoids (CBG, CBC) totaling around 0.3–1.5%, depending on phenotype and cultivation. Terpene totals in well-grown indica-dominant flowers commonly range between 1.2–3.0% by dry weight, a figure that correlates with perceived flavor intensity.

From a cultivation perspective, the genetic heritage suggests a plant that rewards tight environmental control during late flower, as dense indica colas are more susceptible to botrytis if humidity drifts above 55% in weeks 6–9. It also suggests a high calyx-to-leaf ratio relative to older indica lines, which simplifies trimming while preserving bag appeal. Taken together, the heritage points to a practical producer with modern aromas, built by a breeder known for reliable, resinous stock.

Appearance and Morphology

Mountain Deux presents with classic indica morphology: broad leaflets, stout lateral branching, and a compact central cola. Internodal spacing typically ranges from 2–5 cm in controlled indoor environments, allowing for a dense but manageable canopy. In veg, plants often reach 30–50 cm in 3–4 weeks, then finish between 90–130 cm post-stretch when flipped at ~30–40 cm, assuming moderate training.

Flowers are dense, conical, and heavily frosted with glandular trichomes that give a glassy sheen even before peak maturity. Expect a calyx-forward structure with a favorable bract-to-leaf ratio, which reduces trim time while maximizing weight in the jar. Pistils tend to shift from a pale tangerine to copper as maturity approaches, providing a visual cue that aligns with trichome cloudiness.

Color expression can include lime-to-forest greens across the bracts, with occasional anthocyanin blush on sugar leaves under cool night conditions. Dropping night temperatures to 16–18°C (60–64°F) during the last 10–14 days can coax additional color in some phenotypes without compromising resin. Trichome heads typically range 80–120 microns in diameter, a size that washes well for ice water extraction while preserving intact heads for solventless rosin.

Overall bag appeal is high: tight flower structure, vivid pistil contrast, and a heavy trichome blanket that stands out under retail lighting. The cultivar’s compact frame also supports dense planting (6–9 plants/m² in 3–5 gallon containers), enabling canopy optimization without over-vegging. This appearance profile is consistent with a mostly indica, market-ready hybrid designed with both aesthetics and efficiency in mind.

Aroma

Aromatically, Mountain Deux leans into bright citrus and sweet, effervescent notes layered over a resinous evergreen base. Many growers describe a lemon-lime bouquet with hints of candied citrus peel and sparkling soda, a profile that points to limonene and possibly terpinolene or ocimene in supporting roles. Underlying this top-end brightness is often a pine-forward facet suggestive of alpha- and beta-pinene, with myrcene or caryophyllene anchoring the base.

Aroma intensity scales with total terpene content and post-harvest handling, and well-executed runs can deliver pronounced room-filling scent during trim. In sealed jars, the nose tends to open with zesty citrus, then broaden into sweet, resinous, and slightly herbal tones. As the cure progresses over 2–4 weeks, the sharper citrus edges round into lime candy and light floral notes, especially if linalool is present even at minor percentages (e.g., 0.1–0.4%).

From a chemical standpoint, bright lemon-lime profiles commonly correlate with limonene as a top terpene and meaningful contributions from pinene, ocimene, or terpinolene. However, since Mountain Deux is mostly indica, a myrcene-limonene-caryophyllene triad is also plausible and consistent with reported body effects. Expect aromatic persistence that survives grinding and lingers in the air after consumption, a hallmark of terpene totals above ~1.5% by weight.

Flavor

On the palate, Mountain Deux expresses clean, citrus-sweet top notes balanced by pine, herbal, and light earthy undertones. The inhale typically presents lemon zest and lime soda impressions, with sweetness reminiscent of candied peel or green apple candy in some phenotypes. The exhale leans resinous and slightly woody, hinting at pinene and caryophyllene, with a faint floral lift if linalool is present.

Vaporization at 170–185°C (338–365°F) highlights the citrus and floral components while softening the resinous finish. Combustion preserves the lemon-lime signature but deepens the pine and pepper aspects, especially later in a joint or bowl. Mouthfeel is medium-bodied and moderately coating due to resin density, and a properly cured batch leaves a bright, clean aftertaste without grassy notes.

Curing strongly influences flavor clarity. A controlled dry at roughly 18–20°C (64–68°F) and 55–62% RH for 10–14 days, followed by a cure that stabilizes water activity near 0.58–0.62, tends to lock in citrus brightness. Under these conditions, flavor fidelity remains high for 60–90 days in airtight, UV-protected containers.

Cannabinoid Profile and Potency

Given its mostly indica heritage, Mountain Deux is expected to express THC-dominant chemotypes that land in the 18–24% THC range under competent cultivation. Exceptional phenotypes in optimal environments with high-intensity lighting and CO₂ supplementation can test higher, but reproducible, commercial averages tend to cluster in the low-20% range. CBD is typically trace (<1%), with minor cannabinoids such as CBG often registering 0.2–1.0% and CBC in the 0.1–0.5% band.

Potency is strongly environment- and harvest-timing dependent. Trichome ripeness—assessed by the ratio of cloudy to amber heads—modulates perceived effect intensity and character. Harvesting at ~5–10% amber with a majority cloudy often preserves a clearer psychoactive profile, while pushing to ~15–25% amber shifts toward heavier sedation, a nuance many indica-leaning cultivars share.

From a pharmacological perspective, THC’s affinity for CB1 receptors drives the primary psychoactivity, contributing to analgesia, appetite stimulation, and muscle relaxation. Minor cannabinoids can subtly influence the effect curve: for example, CBG is often described as “clarifying,” while CBC may contribute to mood and anti-inflammatory actions in synergy with terpenes. This entourage effect, while variable across phenotypes, often yields a rounded experience that feels stronger than THC percentage alone might suggest.

Consumers should calibrate dose by experience, starting with 1–2.5 mg THC for novices and 5–10 mg for experienced users when ingesting edibles. For inhalation, single draws of a vaporizer or small joint puffs allow stepwise titration, with onset typically in 1–3 minutes, peak effects at 15–30 minutes, and a 2–4 hour duration. Edible onset averages 45–120 minutes with a 6–8 hour duration, magnifying body-related effects common to indica-leaning hybrids.

Terpene Profile and Chemistry

Although no single lab profile defines Mountain Deux across every grow, its reported lemon-lime and resinous character suggests a terpene ensemble anchored by limonene, pinene, and either myrcene or caryophyllene. In modern market samples of indica-leaning hybrids, total terpene content frequently ranges 1.2–3.0% by dry weight, with 2.0%+ considered notably aromatic. Within that range, a plausible breakdown might feature limonene at 0.4–0.9%, beta-caryophyllene at 0.3–0.7%, beta-myrcene at 0.3–0.8%, and supporting fractions of alpha-/beta-pinene, ocimene, linalool, or humulene at 0.05–0.3% each.

Limonene correlates with the crisp citrus nose and is often associated with elevated mood and perceived energy. Beta-caryophyllene, a CB2 receptor agonist, contributes peppery-warm spice and may add anti-inflammatory synergy, particularly when paired with myrcene or humulene. Pinene provides resinous pine and may support alertness and counteract short-term memory effects associated with high THC in some users.

Myrcene often underpins the body feel in indica-leaning profiles, contributing to musky, herbal notes and potentiating perceived sedation at higher doses. Linalool, if present, adds a floral-lavender lift and is associated with anxiolytic properties in preclinical research. Ocimene or terpinolene can appear at low levels in lemon-lime strains, adding a sparkling, effusive top-end, though terpinolene-dominant chemotypes are less common in mostly indica plants.

In extraction, Mountain Deux’s dense trichome coverage translates to competitive return potential. Live rosin makers targeting 73–159 µ wet sieve ranges may see favorable head counts, and experienced producers often report 4–6% rosin yield from fresh frozen (strain-dependent) when total terpene content is above ~2%. As always, results vary by phenotype, harvest timing, and wash technique.

Experiential Effects

Users commonly describe Mountain Deux as a calming, body-forward experience with a clear, gently euphoric headspace at modest doses. The onset is typically smooth and fast with inhalation, beginning in 1–3 minutes and settling into a comfortable plateau within 15–20 minutes. Muscle relaxation and physical ease are primary features, alongside a buoyant mood lift.

At slightly higher doses, sedation deepens, and the strain becomes more couch-friendly without necessarily overwhelming cognition. Many users find it well-suited for winding down after work, watching films, or low-effort creative tasks such as music listening or sketching. Sensory enhancement (flavor perception, music immersion) is noticeable but not overbearing.

In social settings, Mountain Deux can be amiable and chatty at light doses, but the indica body effects take center stage as intake increases. Tasks requiring fine motor precision or rapid short-term memory updates may be affected at higher doses due to THC’s CB1-mediated impacts. Dry mouth and mild ocular dryness are common side effects, and hydration helps mitigate both.

On balance, this is a strain that scales from functional relaxation to sleep-supportive sedation based on dose and harvest ripeness. Many indica-leaning hybrids show their most versatile profile when harvested with minimal amber trichomes and consumed in 1–2 draw increments. Users sensitive to THC should start low and pace intake to avoid transient anxiety or tachycardia that can accompany overconsumption.

Potential Medical Uses

Mountain Deux’s mostly indica profile suggests utility for stress reduction, muscle tension, and sleep support. THC’s analgesic and antispasmodic actions may help with neuropathic discomfort, minor musculoskeletal pain, or menstrual cramps, especially in combination with beta-caryophyllene’s CB2 activity. Anecdotally, users report relief for end-of-day anxiety and ruminative thought patterns, particularly when aromatics include linalool or myrcene.

For sleep, moderate doses taken 60–90 minutes before bed may help shorten sleep latency. If harvested with ~15–20% amber trichomes, the heavier body effects can further aid those who struggle with mid-night awakenings. However, excessive dosing can backfire for some individuals by increasing heart rate or disrupting REM, so titration remains key.

Appetite stimulation is another consistent effect of THC-dominant indica-leaning strains, which can be beneficial for individuals managing appetite loss. Nausea mitigation is frequently reported with limonene-forward chemotypes, and smooth citrus-floral flavors can increase inhalation tolerance for sensitive users. Vaporization at lower temperatures may reduce throat irritation while preserving therapeutic terpenes.

Patients considering Mountain Deux for mood support should note that limonene is associated with uplift in preclinical models, while linalool has shown anxiolytic signals. Beta-caryophyllene’s interaction with CB2 may complement anti-inflammatory aims, which could be relevant in conditions marked by peripheral inflammation. As always, cannabis is not a substitute for medical care, and responses vary widely.

Practical dosing guidelines include starting with 1–2 mg THC for new patients via sublingual or edible routes, or 1–2 short inhalations with a 10–15 minute wait between. Experienced patients might use 5–10 mg orally or 2–4 inhalations, adjusting based on response. Medical consumers should consult clinicians, especially when combining cannabis with sedatives, antidepressants, or antihypertensives.

Cultivation Guide: From Seed to Cure

Genetics and seed form: Mountain Deux comes from Mosca Seeds, who commonly offer both regular and feminized stock across their catalog. Verify the specific release form with your vendor before planning your run. Regardless of seed type, select for vigorous seedlings with symmetrical node spacing and early resin expression during flowering.

Germination and early veg: Use a sterile medium and target a root zone temperature of 22–24°C (72–75°F). Maintain 65–75% relative humidity (RH) and a gentle PPFD of 200–300 µmol/m²/s for the first 5–10 days. Keep substrate pH at 5.8–6.2 for coco/hydro or 6.2–6.8 for soil, and begin feeds at EC 0.6–0.9 (300–450 ppm 500-scale).

Vegetative phase: Mountain Deux’s mostly indica stature makes it ideal for dense canopies. Veg in 3–5 gallon (11–19 L) containers for 3–5 weeks, maintaining temps at 24–26°C (75–79°F) day and 20–22°C (68–72°F) night. Target RH of 60–70% and VPD of 0.8–1.2 kPa, with PPFD of 400–600 µmol/m²/s and DLI of ~20–30 mol/m²/day.

Training: Top once at the 5th node and apply low-stress training (LST) to widen the canopy. Screen of Green (ScrOG) works exceptionally well; fill 60–80% of the net before flip to manage stretch. Internodal spacing of 2–5 cm can be maintained with good light uniformity and airflow.

Pre-flower and flip: Transition to 12/12 when plants reach 30–40 cm, anticipating a modest indica stretch of 1.2–1.7× in the first 2–3 weeks. Increase PPFD to 700–900 µmol/m²/s in early flower and raise CO₂ to 900–1200 ppm if sealed and capable. Adjust VPD to 1.1–1.3 kPa and reduce RH to 55–60% to deter mildew.

Flowering weeks 3–6: This is the bulk-building window. Run PPFD at 900–1100 µmol/m²/s (up to 1200–1300 if CO₂ is 1200–1500 ppm and leaf temps are well-managed). Maintain day temps at 24–27°C (75–81°F), night 19–21°C (66–70°F), and feed at EC 1.6–2.0 (800–1000 ppm 500-scale) with attentive runoff (10–20%).

Defoliation and canopy management: A light defoliation at day 21 post-flip and a cleanup at day 42 help airflow through Mountain Deux’s dense colas. Avoid over-stripping; aim to remove large fan leaves that block key bud sites while preserving enough leaf area for photosynthesis. Keep oscillating fans below canopy level and above the canopy to disrupt microclimates.

Late flower weeks 7–9: Lower RH to 45–52% and hold VPD at 1.3–1.6 kPa to prevent botrytis in dense flowers. Consider a mild temperature drop at night (2–4°C) to encourage color expression in susceptible phenotypes without sacrificing resin. Many mostly indica cultivars, including Mountain Deux, finish in 56–63 days; scout trichomes at day 49 and beyond.

Nutrient strategy: Provide a balanced macro profile emphasizing K and P during mid-late bloom, while avoiding excessive nitrogen after week 4 of flower. Calcium and magnesium support should be steady in coco/hydro (100–150 ppm Ca, 50–70 ppm Mg). In soil, topdress with a bloom mix around flip and again at week 3–4, ensuring even moisture for mineralization.

IPM and plant health: Begin with preventative measures rather than reactive sprays. Rotate biologicals such as Bacillus subtilis and Bacillus amyloliquefaciens for foliar disease suppression in veg, and employ predatory mites (Amblyseius swirskii, A. californicus) as needed. Maintain good sanitation, quarantine new clones, and filter intake air to reduce pest pressure.

Harvest timing: Use a 60–100× loupe to evaluate trichomes on mid-canopy flowers. For a balanced effect, harvest at ~5–10% amber and 80–90% cloudy; for heavier sedation, let amber reach ~15–25%. Avoid harvesting based solely on pistil color, as stigma oxidation lags behind gland maturity.

Flush and finish: In inert media, a 7–10 day low-EC finish (EC 0.2–0.4 with clean water or a light finishing solution) can improve burn quality and ash color. In living soil, simply provide plain water with proper pH for the last 7–10 days and avoid overwatering. Aim to keep plants turgid and avoid severe fade that can prematurely stall resin production.

Drying: Target 18–20°C (64–68°F) and 55–62% RH in the dry room, with gentle air exchange and no direct airflow on flowers. Whole-plant or large-branch hangs typically take 10–14 days; denser Mountain Deux colas benefit from the slower end of that range. A proper dry preserves terpenes and prevents chlorophyll bite.

Curing: After stem-snap, trim and jar at a fill level of ~70–80% volume, monitoring with mini hygrometers. Burp jars as needed to stabilize at 58–62% RH, aiming for water activity between 0.58–0.62 for long-term storage. A 3–4 week cure markedly enhances Mountain Deux’s citrus clarity and smooths the resinous finish.

Yields: In dialed indoor conditions with moderate veg and training, expect 450–600 g/m² under high-efficiency LEDs (PPFD 900–1100 µmol/m²/s). Outdoor or greenhouse plants in 30–50 gallon containers can reach 700–1200 g per plant with adequate sunlight and IPM. Phenotype selection impacts yield variance more than any single parameter—keep vigorous, uniform keepers.

Outdoor guidance: In temperate northern latitudes (35–45°N), plan for an early–mid October harvest to beat heavy fall rains, given Mountain Deux’s dense flower structure. Choose sites with strong morning sun and steady airflow, and prune lower third growth for better energy distribution. Keep RH and dew exposure in mind; supportive trellising prevents branch snap under late-season weight.

Lighting and CO₂ specifics: For best results, run 900–1200 µmol/m²/s PPFD in flower with 1200–1400 ppm CO₂, targeting a leaf surface temperature of ~28–29°C (82–84°F). If not supplementing CO₂, cap PPFD near 900–1000 and maintain leaf temps around 25–26°C (77–79°F) to prevent photoinhibition. Uniformity (±10% PPFD across canopy) is often worth more than peak intensity.

Extraction considerations: Mountain Deux’s resin density and head size make it suitable for both hydrocarbon and solventless runs. If washing fresh frozen, harvest at peak cloudiness to maximize intact head yield and consider a 24–48 hour pre-freeze at –20°C or lower. For flower rosin, 180–200°F plates and a 1–2 minute press window typically preserve citrus-forward volatiles while achieving stable yield.

Quality control: Record environmental metrics (temp, RH, VPD, EC, pH, PPFD, CO₂) daily and correlate them with plant response and lab results. Consistency in these parameters is strongly predictive of terpene retention and potency; even a 5–10% drift in RH during late flower can influence botrytis risk and post-harvest success. Tight process control pays dividends in both bag appeal and repeatability.
