Written by Ad OpsOrigins and Breeding History of MS #29
MS #29 is a numbered hybrid from Karma Genetics, a Dutch breeder renowned for elite OG and hybrid work since the mid-2000s. Karma Genetics has collected numerous trophies for lines like Biker Kush, Headbanger, and White OG, establishing a reputation for resin-forward selections and robust, production-ready plants. Within this context, MS #29 reflects the brand’s methodical selection style, where keeper phenotypes are tracked with working numbers before or alongside formal cultivar names.
Public documentation on MS #29 is sparse, which is common for breeder selections still circulating among connoisseurs and testers. The designation suggests MS #29 was culled from a larger hunt, with the number indicating a standout phenotype among many siblings. In practice, that means what growers and consumers encounter as MS #29 captures a specific expression chosen for its balance of potency, resin, and aroma.
Karma Genetics is well-known for combining classic fuel, pine, and citrus profiles with modern bag appeal and yield. Their hybrids often marry OG structure with improved branching, better calyx-to-leaf ratios, and bolder terpene intensity. MS #29 fits the house style, delivering a hybrid that reads as indica and sativa in equal measure while pushing resin density suited for both flower and extraction.
Genetic Lineage and Heritage
The heritage of MS #29 is indica and sativa, presenting as a balanced hybrid in growth and effect. Karma Genetics frequently works from OG-leaning and broadly hybridized pools, so MS #29 can be reasonably expected to carry influences from fuel, pine, citrus, or chem families. That said, the exact parentage has not been publicly disclosed by the breeder as of this writing.
In the wider market, hybrids with this pedigree trend toward THC-dominant chemotypes with minor cannabinoids present in trace to low percentages. State-licensed lab data in mature markets like Oregon and Washington routinely show hybrid flower testing from 16% to 28% THC, with medians around 19% to 21%. MS #29 is likely to fall within that distribution, though real-world potency depends on phenotype, environmental control, and post-harvest handling.
From a grower’s perspective, the indica-sativa blend manifests in medium internodal spacing, moderate to strong lateral branching, and a 1.5x to 2.0x stretch after flip. The structure supports topping, mainlining, and screen training without the extreme sprawl of long-flowering sativas. For breeders and pheno hunters, MS #29 offers a selection platform to capture fuel-forward density or citrus-pine brightness, depending on the cut.
Appearance and Morphology
In flower, MS #29 typically presents medium-density colas with a balanced calyx-to-leaf ratio and an easy manicure. Buds tend to be conic to spear-shaped on primary tops, with smaller golf-ball nuggets on laterals. Expect bright forest-green hues with lime highlights and thick stippling of amber to rust pistils once mature.
Under dialed environments, trichome coverage is generous, with swollen heads and short to medium stalks that shimmer even under low-intensity light. Resin ring formation on sugar leaves is common, a hallmark of Karma Genetics’ resin-forward selection criteria. With nighttime temperatures dropping 5 to 10 degrees Fahrenheit late in flower, some phenotypes may flash lavender fringes due to anthocyanin expression.
Internodal spacing runs moderate, making MS #29 manageable in small rooms yet scalable in larger canopies with trellising. Plants respond well to topping at the fifth or sixth node, producing even canopies that fill a 2x2 to 3x3 foot footprint per plant indoors. Outdoors, a single plant in a 50 to 100 gallon pot can form a sturdy bush with substantial secondary colas if trained early.
Aroma: Nose Notes and Volatiles
The nose of MS #29 leans hybrid, bridging gas, citrus, and earth with a piney sparkle. On dry pull, many cuts express zesty lemon-lime top notes over a warm, peppery base, indicative of limonene and beta-caryophyllene interplay. Subnotes can include sweet cream, faint floral lift, and a camphor coolness that hints at pinene or eucalyptol in trace amounts.
Breaking the bud amplifies volatile terpenes, moving the bouquet from subtle to room-filling within seconds. The shift often reveals a diesel-like edge, a trait associated with Karma lines that carry OG and chem ancestry. If cured at 60 to 62 percent relative humidity, the profile refines from loud top notes to a more layered, dessert-meets-fuel complexity over two to four weeks.
Aroma intensity is strongly influenced by harvest timing, drying conditions, and storage. Flowers dried for 10 to 14 days at 60 Fahrenheit and 60 percent RH tend to retain more monoterpenes associated with brightness. In contrast, faster drying at low humidity can flatten the citrus and pine, leaving a heavier, pepper-forward earth.
Flavor and Mouthfeel
On the palate, MS #29 typically opens with lemon-zest brightness and a light pine bite, quickly followed by diesel-like depth. The mid-palate often delivers a peppery warmth that can tingle the tongue, balancing the initial citrus. Exhale leaves a lingering herbal resin and faint sweetness, a satisfying finish for both joint and vaporizer use.
Combustion in glass maintains the top-notes best during the first two or three pulls, after which the profile moves into earthy-spice territory. Clean vapor at 350 to 390 Fahrenheit tends to emphasize citrus and pine, while 400 to 430 Fahrenheit unlocks deeper fuel and pepper. Many users report the flavor persists through multiple draws, indicating above-average terpene loading when grown and cured correctly.
Mouthfeel is medium-bodied, not overly heavy, with a light coating quality that enhances perceived richness. In concentrates, especially live resin and live rosin, MS #29 can read louder and sweeter, as the extraction preserves volatile monoterpenes. Expect a flavor arc that mirrors the aroma: bright entry, structured middle, and a long, resinous exit.
Cannabinoid Profile and Potency
Most MS #29 cuts will be THC-dominant, with CBD typically under 1 percent. In legal U.S. markets between 2019 and 2024, hybrid flower commonly ranges from 18 to 26 percent THC, with outliers above 28 percent and a median near 20 percent. MS #29 selections grown under high-intensity light with optimal fertigation and CO2 enrichment may land toward the higher end of that range.
Minor cannabinoids can include CBG at 0.1 to 1.0 percent, CBC at trace to 0.3 percent, and THCV generally trace to 0.5 percent. The exact profile depends on cut and harvest maturity, as CBG often diminishes as THC synthesizes late in flower. For extract producers, preserving acidic forms like THCa and CBGa in fresh-frozen material can yield more nuanced lab readouts.
Potency is not a guarantee of experience or efficacy, and blind studies show consumers often misjudge effects based solely on THC percentage. Controlled testing has found that perceived intensity correlates with terpene content and ratio as much as with THC alone. As a benchmark, total terpene content above 2.0 percent by weight often correlates with stronger flavor and a fuller, more complex high even at moderate THC percentages.
Terpene Profile and Chemical Bouquet
While precise terpene ratios vary by phenotype, MS #29 is likely to express a limonene, beta-caryophyllene, and myrcene triad. Many Karma hybrids show additional linalool or alpha-pinene support, which contributes lavender-like calm and brisk pine, respectively. Total terpene content for well-grown indoor flower commonly lands between 1.5 and 3.0 percent by weight.
Limonene contributes citrus lift and mood elevation; beta-caryophyllene binds to CB2 receptors and provides peppery spice with anti-inflammatory potential; myrcene softens the edges with a herbal-sweet base and can read musky or mango-like. Alpha-pinene adds a green, pine forest snap and may counter short-term memory fog at low doses in some users. Linalool, even in small amounts, can impart floral top notes and a soothing undertone that pairs well with evening use.
Post-harvest handling strongly affects terpene retention. Studies on terpene volatility show that rapid, hot drying can reduce monoterpenes by double-digit percentages, while low-and-slow methods preserve them. Cure metrics around 60 Fahrenheit, 60 percent RH, and stable water activity between 0.55 and 0.65 encourage ester formation that deepens flavor over weeks.
Experiential Effects and User Reports
MS #29 reads as a hybrid with a calm, euphoric onset that settles into a grounded body relaxation. Many users describe a mood-lift and social clarity within 5 to 10 minutes when inhaled, lasting 2 to 3 hours depending on tolerance. The body feel is present but not anchoring at moderate doses, making it suitable for daytime through early evening use.
At higher doses, a heavier, couch-leaning calm emerges, often accompanied by a warm, behind-the-eyes pressure characteristic of OG-influenced hybrids. Creative focus can spike during the first hour, tapering into contented ease with a reduced urgency to task-switch. Users who are sensitive to limonene-forward strains may feel a bright, almost sparkling headspace in the first 15 to 30 minutes.
Common side effects include dry mouth and dry eyes, which surveys routinely place as the most frequent cannabis adverse events across product types. THC-related anxiety is possible in sensitive individuals, especially above 20 milligrams oral or several potent inhalation pulls in quick succession. Newer consumers are well served by pacing intake, hydrating, and pairing with a calming environment to steer the experience.
Potential Medical Applications
MS #29’s balanced profile makes it a candidate for managing stress, transient anxiety, and mood dysregulation in low to moderate doses. Limonene-rich chemotypes have been associated in preclinical research with antidepressant-like effects, while linalool and myrcene can add calm and sleep support. Beta-caryophyllene’s CB2 affinity suggests potential for inflammatory modulation without adding intoxication on its own.
For pain, THC remains the primary driver of perceived relief, particularly neuropathic and musculoskeletal discomfort. In observational studies, hybrid flower is commonly selected by patients for mixed pain and stress presentations where a strictly sedating or purely stimulating effect is undesirable. MS #29 aligns with that use case, delivering a middle path between alertness and relief.
Appetite stimulation and nausea reduction may also be supported by THC-dominant profiles like this one. Patients should note that higher doses can compound sedation and anxiety in opposite directions depending on personal neurochemistry. As always, medical use should be coordinated with a clinician, especially when combining with existing prescriptions or in conditions sensitive to changes in blood pressure or heart rate.
Processing Potential: Live Resin, Rosin, and Vape Readiness
The flavor density and resin coverage of MS #29 make it a strong candidate for live resin and live rosin production. Fresh-frozen extraction captures monoterpenes such as limonene and pinene that give carts and disposables their top-note sparkle. When properly harvested and processed, MS #29 can yield a lively, citrus-forward inhale layered over fuel and pepper.
Across the legal market, consumer guides have emphasized how live resins and rosins showcase a strain’s inherent terpene complexity in vapes. For example, Leafly’s seasonal coverage of the tastiest THC vapes highlights the dominance of live resin and live rosin formats for maximum flavor retention, underscoring why terpene-rich cultivars translate so well to cartridges and disposables. MS #29’s hybrid aroma array aligns with that trend, offering a balanced, expressive profile that holds up in both dab and cartridge form.
Producers should target biomass frozen within an hour of harvest to minimize terpene loss, and store at subzero temperatures until extraction. Post-extraction, carts filled with terpene levels in the 7 to 12 percent range tend to balance flavor and hardware stability, though this varies by hardware and oil viscosity. For rosin, a 160 to 190 Fahrenheit press on 73 to 120 micron bags typically preserves brightness while maintaining flow.
Comprehensive Cultivation Guide
Environment and planning. MS #29 thrives in controlled environments that keep temps around 78 to 82 Fahrenheit in veg and 74 to 80 Fahrenheit in flower. Relative humidity should start at 60 to 70 percent in early veg, tapering to 50 to 55 percent mid-flower and 45 to 50 percent late flower to limit botrytis risk. Vapor pressure deficit between 0.9 and 1.2 kPa encourages steady transpiration without stress.
Lighting. Target a photosynthetic photon flux density of 350 to 500 µmol m⁻² s⁻¹ for seedlings, 600 to 800 for veg, and 900 to 1,100 for bloom under high-efficiency LEDs. With CO2 enrichment at 1,000 to 1,200 ppm, the canopy can comfortably utilize 1,200 to 1,400 µmol during peak bloom if irrigation and nutrients are optimized. Maintain 18 hours light in veg and 12 hours in flower; expect a 1.5x to 2.0x stretch over the first 14 to 21 days after flip.
Medium and nutrition. MS #29 performs well in coco-perlite blends at 70-30 for frequent fertigation, as well as in living soil where microbial diversity buffers feed swings. In coco, start vegetative EC around 1.2 to 1.6 mS cm⁻¹, rising to 1.8 to 2.2 in mid to late flower depending on cultivar appetite. Maintain pH 5.7 to 6.0 in veg and 6.0 to 6.2 in bloom for coco; in soil, pH 6.2 to 6.8 stabilizes micronutrient uptake.
Irrigation cadence. In coco with 1 to 3 gallon pots, run multiple small feeds to 10 to 20 percent runoff, targeting 2 to 4 irrigations per day under high light. In living soil, water less frequently but to full saturation, allowing for 10 to 15 percent runoff to prevent salt buildup even with organic inputs. Aim for pot dry-back that reaches roughly 50 to 60 percent of saturation mass before next irrigation, adjusted for plant size and climate.
Training and canopy management. Top once or twice in veg around the 5th to 6th node and spread branches under a single or double trellis. Screen of green methods help even colas, while sea of green can also excel with small plants flipped early to manage stretch. Defoliate lightly at day 21 and day 42 of flower to increase airflow and light penetration without stripping fan leaves excessively.
Plant size and spacing. Indoors, allocate 2x2 to 3x3 feet per topped plant for a long veg, or 1x1 to 1.5x1.5 feet for a short veg multi-plant run. Outdoors in full sun, MS #29 can grow into a multi-pound bush in 50 to 100 gallon fabric pots with early topping and caging. Maintain wide aisles and airflow to deter powdery mildew during humid spells.
Flowering time and yield. Expect a 9 to 10 week bloom window, with some phenotypes finishing around days 63 to 70 and resin-heavy expressions pushing to day 70 to 75 for full swell. Indoor yields commonly reach 1.5 to 2.5 pounds per 4x4 footprint under optimized LEDs, translating to roughly 500 to 750 grams per square meter. Outdoor yields of 1.5 to 3.0 pounds per plant are achievable with long veg and strong sun, cultivar-dependent.
CO2 and climate steering. If enriching CO2, start at 900 ppm and ramp to 1,100 to 1,200 ppm through mid-flower, ensuring increased irrigation and EC adjustments to match accelerated growth. Use pulse-deficit steering to encourage generative growth early bloom with slightly drier substrate, shifting to more vegetative steering mid-bloom for bulking, then finishing generatively with higher EC and lower humidity. Temperature drops of 5 to 10 degrees Fahrenheit at night can tighten internodes and color expression late in flower.
IPM and disease pressure. MS #29 is not unusually susceptible, but like most resinous hybrids, dense tops can invite botrytis and powdery mildew if humidity spikes. Implement weekly IPM rotations in veg using biologicals like Bacillus subtilis and Beauveria bassiana, plus predatory mites for thrips and spider mites. In flower, rely on environment, beneficials, and canopy airflow, avoiding foliar sprays beyond early bloom.
Harvest readiness and metrics. Evaluate trichomes at 60x magnification; many growers prefer a 5 to 15 percent amber ratio, with the rest cloudy for a balanced effect. For a brighter headspace, harvest closer to all-cloudy; for deeper body effects, allow more amber development. Target whole-plant hang in a dark room at 60 Fahrenheit and 60 percent RH for 10 to 14 days until small stems snap.
Curing and storage. After dry, buck and jar or bin-cure at 62 percent RH, burping daily for the first week and then weekly for a month. Water activity between 0.55 and 0.65 is a reliable metric for stability and terpene preservation. Long-term storage in nitrogen-flushed, light-proof containers at 55 to 60 Fahrenheit reduces oxidation and preserves monoterpenes.
Cloning and mothers. MS #29 clones readily from healthy greenwood taken 7 to 10 days before flip or from dedicated mothers. Use a mild rooting solution with 0.2 to 0.4 EC and a dome humidity of 80 to 95 percent for the first 3 to 5 days, then wean to ambient over a week. Root formation is commonly seen at days 7 to 14; plant into small pots to encourage dense root balls before up-potting.
Extraction considerations. For live resin or rosin, harvest at peak terpene production around late week 8 to early week 10 depending on phenotype, and freeze immediately. Aim for clean material free of PM and pests, as these contaminants concentrate in extracts. Many MS #29 phenos press well at 160 to 190 Fahrenheit with yields that reflect its resin-forward selection, though exact percentages vary by cut and technique.
