Martian Kush is a mostly indica cultivar bred by DNA Genetics Seeds, a pioneering Dutch–Californian seed company known for cup-winning hybrids and Kush refinements. Released during the wave of OG-dominant crosses in the late 2000s and early 2010s, Martian Kush was positioned as a connoisseur hybrid that balanced potency with a brighter, heady uplift. DNA built its reputation through projects like OG #18, Skywalker Kush, and LA Confidential, and this strain sits squarely in that lineage of resin-forward, terpene-rich work. Its rollout to European coffeeshops and North American dispensaries established it as a boutique option favored by growers as much as end consumers.
While breeder literature is succinct, community consensus places Martian Kush as a cross between Martian Mean Green and OG #18, combining a hazy, high-energy parent with a heavy, fuel-leaning Kush selection. This pairing was designed to inject vigor, yield, and a more dynamic terpene spectrum into the classic OG architecture. The result is an indica-dominant cultivar with sativa-leaning sparkle in its mood and flavor top-notes. Many growers report it captures the best of both worlds: fast sedation from the Kush side and a saucy, citrus-pine nose from the Martian Mean Green lineage.
Market naming around Martian Kush has occasionally produced confusion. Community menus and review sites have sometimes used the moniker “Purple Martian Kush (PMK),” and that label has appeared alongside other strains in user-generated catalogs. For example, Purple Martian Kush (PMK) is referenced in association with unrelated pages, including Granddaddy Purple and Critical Sensi Star, highlighting how shop-level nicknames can drift across genetics. The upshot is that “PMK” often signifies a purple-leaning phenotype or a local cut rather than an official, breeder-defined variety.
Despite the aliasing, the core identity of Martian Kush remains consistent: a DNA Genetics Seeds hybrid with a measurable indica tilt and a pronounced OG backbone. Growers who obtain verified seed packs or cuts from reputable sources report similar morphology and flowering timelines, even as terpene emphasis may vary by phenotype. That combination of recognizable structure and variable aromatics helps explain why the cultivar attracts both production-minded and craft-focused gardens. In competitive markets, recognizable family trees give consumers confidence while pheno diversity keeps menus interesting.
Documentation from strain aggregators underscores Martian Kush’s presence in the broader seed and strain ecosystem. For instance, CannaConnection’s sitemap lists Martian Kush alongside related entries, indicating ongoing coverage in public databases. Over the last decade, the cultivar has persisted through several waves of market preferences, from cookie-dominant trends to dessert gas fads. Its staying power is rooted in a balanced effect profile and a cultivation experience that rewards careful dialing without punishing minor mistakes.
Genetic Lineage and Phenotypic Variation
The accepted lineage of Martian Kush is Martian Mean Green × OG #18, a pairing that threads haze-influenced terpenes into a dense, OG-style plant. Martian Mean Green contributes vigor, longer internodes, and an aromatic spectrum spanning citrus, pine, and herbal incense. OG #18, a celebrated selection from DNA/Reserva Privada, adds density, fuel-forward volatiles, and heavy trichome production. The resulting hybrid is mostly indica by effect, yet it can express sativa-like aromas and a lively initial onset.
Phenotypic spread typically clusters into two common expressions. The first is an OG-leaning pheno with squat stature, tighter internodes, and dominant fuel, lemon, and pepper notes; this selection often finishes faster and packs on denser colas. The second is a Martian Mean Green–influenced pheno that runs slightly taller, with more open structure and a louder citrus-pine profile layered over earth and spice. Both phenos show strong trichome coverage, though the OG-leaner commonly measures higher in β-caryophyllene and limonene ratios.
Coloration can vary with temperature, feed, and genetic lean, leading to occasional purple expression late in flower. Cooler night temperatures in the final two weeks—especially below 60–62°F (15.5–16.5°C)—can trigger anthocyanin development in susceptible phenos. This has fed into occasional marketplace references to “Purple Martian Kush (PMK),” though the purple trait is not a guaranteed hallmark of the cultivar. Growers chasing color should do so carefully, as overly cold swings can compromise yield and terpene retention.
From a breeding standpoint, Martian Kush’s balance of resin output and hybrid vigor has made it an attractive parent in small-batch projects. Its OG structure stabilizes internodal spacing and calyx-to-leaf ratios, improving trim times and bag appeal in polyhybrids. Meanwhile, the hazy terps from Martian Mean Green add market-friendly brightness that pairs well with fruit or dessert-line mothers. The net effect is a parent that can transmit both weight and personality in outcrosses.
Environment substantially influences expression. Under high-intensity LED at 900–1,200 µmol/m²/s PPFD, the OG-leaning pheno compacts and pushes oilier, gaseous aromatics; under lower intensity or warmer rooms, the citrus-herbal top notes expand. Hydroponic setups often emphasize limonene and β-myrcene presence, whereas organic, living soil builds tend to round the terpene curve with linalool and humulene traces. This interplay makes phenohunting worthwhile even for small home gardens.
Appearance
Martian Kush presents with medium-height plants that are visibly OG in architecture yet slightly more open than classic Kush blocks. The canopy typically fills with golf-ball to soda-can colas, showing good apical dominance with responsive lateral branching. Internodes measure compact to medium, and the calyxes stack tightly toward harvest, developing a sandy-to-frosty trichome sheen. Mature sugar leaves are slender to medium width, with occasional serration cupping during peak feed.
Buds are dense and resinous, often finishing with a silvery cast from copious heads and stalks. Calyx-to-leaf ratios are favorable for hand and machine trim alike, cutting down processing time without sacrificing aesthetic. Pistils tend to begin a vivid tangerine and fade toward rust as the plant approaches day 60–70 of flower. Under optimal conditions, the top colas can weigh considerably, making support netting prudent in week 5 onward.
Color expression spans forest green to olive, with darker hues on OG-leaning phenotypes. In gardens that drop night temperatures late, anthocyanin expression can paint the calyx tips and sugar leaves with violet accents. This is not ubiquitous, but it aligns with the sporadic “PMK” nickname some dispensaries have used for purple-leaning batches. The underlying chlorophyll content remains high, keeping the core tone rich and photogenic even without purple.
Trichome heads frequently mature to cloudy with 10–20% amber around day 63–70, depending on environment and pheno. Many growers note large, bulbous capitate-stalked heads averaging 70–90 microns—a favorable size for ice water hash and dry sift. The stickiness is pronounced, with fresh trim exhibiting tacky fingers and scissor lock in under two branches. This resin profile also supports long-term jar appeal when cured correctly.
Overall bag appeal is high, driven by the combination of weight, frost, and a modern terpene bouquet. When grown with sufficient light density, top colas maintain an attractive, conical form with minimal foxtailing. Suboptimal heat or overfeeding late can induce slight foxtails, but careful VPD and EC management limit this risk. The result is a photogenic flower that stands out on a shelf next to sweeter dessert lines.
Aroma
Aromatically, Martian Kush is complex and layered, reflecting contributions from both parents. Top notes often open with bright lemon zest and sweet citrus, a nod to Martian Mean Green’s influence. Underneath, a core of petrol, earthy pine, and cracked black pepper builds a classic OG-style base. Together, the bouquet reads as citrus fuel with herbal incense and a peppery snap.
In fresh flower, limonene-driven brightness can dominate the nose, especially during weeks 6–8 of bloom. Cure shifts the balance toward β-caryophyllene and myrcene, deepening the gas and earth while preserving a citrus lift. Many growers report the aroma intensity jumping markedly after a 10–14 day slow dry and 3–4 weeks of cure. The transition brings out additional nuances like eucalyptus, bay leaf, and faint clove.
Mechanical agitation during trimming releases pungent, pepper-lemon volatility that lingers in small rooms. Jar opens often deliver a two-stage experience: initial lemon-pine flash followed by a diesel-funk tail that clings to the palate. When ground, floral and herbal accents surface, reminiscent of dried rosemary and faint lavender. This layered effect suggests a terpene ensemble led by limonene, β-caryophyllene, and myrcene, with supporting pinene and linalool.
Variability exists across phenotypes, and environmental differences can tilt the nose significantly. Hydroponic and coco grows frequently present as sharper lemon-fuel with crisp pine, while organic soil grows round the profile into sweet citrus, forest earth, and spice. Cooler late bloom can also accentuate herbaceous and floral facets while slightly muting overt solvent-like gas. These nuances make it a rewarding strain for aroma-focused cultivators.
Even at small scale, perceived aroma intensity is high. Many users rate the loudness as 7–9 out of 10 in community reports, escalating to 9–10 after a dialed cure. In retail environments, Martian Kush tends to stand out in sniff jars due to its quick, bright pop and lingering diesel backbone. That contrast makes it an effective counterpoint to sugary cookie or cake profiles on a menu.
Flavor
The flavor of Martian Kush tracks the nose but skews slightly sweeter across the first draws. Inhalation typically introduces lemon-lime zest and sweet citrus candy, followed by pine sap and cracked pepper. Exhale accentuates diesel, earthy loam, and a pepper-citrus finish that tingles the tongue. With vaporization at 180–195°C, floral and herbal notes become more pronounced, delivering a cleaner, perfumed expression.
Combustion versus vaporization influences the experience dramatically. Vaporization tends to spotlight limonene and pinene, creating a brisk, menthol-like clarity on the palate. Combustion emphasizes β-caryophyllene and myrcene, deepening the spice and earth while adding a roasted, faintly chocolate undertone. Those who enjoy OGs typically prefer a mid-temp joint or cooler glass to preserve the citrus sparkle.
The finish often lingers for several minutes, with a mouthwatering effect tied to citrus volatiles. Hydration and glass cleanliness strongly affect flavor clarity; resinous builds in pipes can skew the profile toward bitterness. A 3–4 week cure in 62% RH jars consistently improves sweetness and cohesion of the citrus and gas. At 8+ weeks of cure, the profile rounds further, trading sharp lemon for candied peel and warm spice.
Phenotype plays a clear role in flavor emphasis. OG-leaners drive heavier diesel and pepper at higher temperatures, while Martian-leaners keep grapefruit, lemon, and pine center stage even when combusted. Growers targeting flavor should avoid high nitrogen late bloom and keep dry-backs controlled to prevent harshness. When executed carefully, Martian Kush delivers a modern gas-citrus profile that competes with boutique OG crosses.
Cannabinoid Profile
Martian Kush typically tests as THC-dominant with low CBD. Verified lab panels reported by cultivators show THC ranges commonly between 18% and 24% by dry weight, with exceptional cuts crossing 25% under optimized lighting and feed. CBD usually remains below 0.5%, and total minor cannabinoids—CBG, CBC, and trace THCV—usually land in the 0.5–1.5% aggregate range. Total cannabinoids in well-grown samples often read 20–27%.
The conversion from THCA to THC through decarboxylation follows standard kinetics, with cured flower often listing 20–26% THCA and 0.5–1.5% THC pre-decarb. Post-decarb products thus reflect high-potency inhalation experiences and robust infusion potential for edibles. Because THCA is the bulk of the acid form in raw buds, storage conditions matter; warm storage can slow-decarb and degrade terpenes. Ideal storage is 15–20°C and 55–62% RH in UV-opaque glass.
Batch-to-batch variation is typical and tied to phenotype, grow method, and harvest window. Earlier harvests at ~10% amber trichomes can tilt toward a slightly more energetic effect with comparable THC but lower perceived heaviness. Later harvests at ~20–30% amber may feel more sedative, even when measured THC changes minimally, due to terpene shifts and potential cannabinoid oxidation. Growers targeting a balanced profile generally harvest around day 63–67 for most phenotypes.
Concentrate yields from Martian Kush are strong, mirroring OG-forward resin density. Hydrocarbon extraction can return 18–25% from cured material and 5–7% terpene mass fraction in fresh-frozen, depending on cut. Ice water hash makers report first-pull returns of 3–5% with total multi-wash yields of 4–7%, aided by 70–120 µm trichome head distribution. These figures align with other OG hybrids known for solventless potential.
Consumers should remember that cannabinoid numbers do not fully predict effect character. Terpene synergy, minor cannabinoid presence, and personal neurochemistry all shape subjective outcomes. For Martian Kush, adequate terpene content—often 1.5–2.5% by weight in dialed batches—correlates with fuller, more satisfying effects at lower dose. This makes the strain efficient for both recreational and therapeutic users.
Terpene Profile
Analytical profiles commonly position limonene, β-caryophyllene, and β-myrcene as the lead terpene trio in Martian Kush. In dialed indoor runs, total terpene content often ranges from 1.5% to 2.5% by weight, with standout phenos pushing near 3.0% under ideal drying and curing. Limonene frequently measures 0.4–0.8%, contributing lemon-citrus zest and a perceived uplift in mood. β-Caryophyllene often lands between 0.3–0.7%, providing peppery spice and potential CB2 receptor activity.
β-Myrcene commonly appears at 0.2–0.6%, lending earthy, herbal depth and softness to the smoke. Supporting terpenes include α-pinene and β-pinene (0.05–0.25%), which reinforce pine, resin, and perceived clarity, and linalool (0.05–0.15%), adding floral, faintly lavender notes. Humulene and ocimene may show in trace to moderate amounts, reflecting herbal and slightly sweet green facets. The exact balance depends heavily on phenotype and substrate.
Terpene expression is sensitive to environment, especially light intensity, root-zone temperature, and post-harvest handling. Maintaining leaf-surface temperatures near 25–27°C with 900–1,100 µmol/m²/s PPFD in late bloom supports robust limonene and pinene retention. Over-drying below 50% RH or fast-drying above 24°C can volatilize limonene disproportionately, flattening the profile. A 10–14 day slow dry at 58–62% RH preserves the citrus top notes and gas.
Living soil and organic inputs can enrich the secondary terpene ensemble. Many organic growers report more rounded linalool and humulene contributions, giving Martian Kush a slightly sweeter perfume during cure. Conversely, salt-based regimens with careful sulfur and magnesium balance tend to emphasize gas and pepper from caryophyllene. Either path can be successful; the choice depends on the desired expression on the nose and palate.
From a consumer standpoint, the terpene blend explains the cultivar’s dual personality: bright and invigorating up top, grounded and soothing beneath. Limonene and pinene lend alertness and positive mood, while myrcene and caryophyllene anchor the body effect. This balance is a hallmark of many OG hybrids but is especially well integrated here. It helps Martian Kush perform across daytime microdoses and evening decompression sessions.
Experiential Effects
Martian Kush delivers a fast-acting onset with a layered trajectory, reflecting its mixed heritage. Within 2–5 minutes of inhalation, most users report a clean lift in mood and sensory brightness, often described as a citrus “switch on.” By the 10–20 minute mark, a warm, pressure-relieving body melt phases in, with muscle relaxation and slowed mental pacing. Peak effects typically last 90–150 minutes, tapering gently into a calm afterglow.
Subjectively, many describe the headspace as clear but comfortably slowed, avoiding the heavy mental fog characteristic of some pure OG cuts. Conversation and creative activities often feel easier during the first hour, with attention to detail improving in quiet environments. Overconsumption, however, can push the experience toward couchlock and introspective loops, especially for novice users. The key is dose control given the strain’s high THC potential.
Physiologically, common reports include reduced muscle tension, softening of restlessness, and an easing of background aches. Appetite stimulation is moderate to notable, rising as the body effect deepens. Dry mouth and dry eyes are the most frequent side effects, with occasional lightheadedness at higher doses. Paranoia is uncommon at moderate doses but can appear if set and setting are poor or tolerance is low.
Martian Kush’s balance makes it adaptable across time-of-day with dose adjustments. At 5–10 mg THC inhaled equivalent (one to three average hits), users often find it suitable for afternoon relaxation without full sedation. At 15–25 mg equivalent, it shifts squarely into evening territory, pairing well with movies, low-intensity social time, or pre-sleep wind-down. Edible effects mirror this pattern, with onset 45–90 minutes and duration 3–5 hours.
Because of its terpene ensemble, the experience maintains character even at sub-psychoactive microdoses. Small amounts—one quick pull or a 1–2 mg edible—can deliver perceived stress relief and mood smoothing without intoxication. Those with low tolerance should start with minimal inhalations and wait 10 minutes before re-dosing. The cultivar rewards patience, as the body relaxation often arrives later than the mood lift.
Potential Medical Uses
Martian Kush’s profile aligns with several commonly reported therapeutic targets. Its mix of high THC and β-caryophyllene–forward spice suggests potential for alleviating mild to moderate pain, including tension headaches and musculoskeletal discomfort. Myrcene’s presence may contribute to perceived muscle relaxation and improved sleep onset when dosed in the evening. Limonene and pinene can support mood elevation and perceived stress reduction during the first phase of effects.
Patients managing insomnia often report benefit from 10–20 mg THC inhaled equivalent taken 60–90 minutes before bed. The gently sedating tail helps ease sleep onset without the abrupt knockdown associated with heavier Afghan or pure Kush lines. For daytime anxiety management, microdosing with 1–3 mg THC or one small inhalation may provide calming without cognitive impairment. As always, individual responses vary and should be titrated carefully.
Appetite stimulation is another consistent effect, making Martian Kush of interest for those facing appetite loss. Inhaled doses typically prompt hunger within 30–45 minutes, with effects persisting for 60–120 minutes. For nausea, rapid-onset inhalation can be useful, though those sensitive to smoke may prefer vaporization. Vaporizing at 180–190°C can reduce throat harshness while keeping efficacy.
Inflammatory conditions are a common area of interest due to β-caryophyllene’s activity at CB2 receptors, although human clinical data remain limited. Some patients report subjective relief from inflammatory flare-ups when using Martian Kush products, especially in combination with CBD. Adding a 5–10 mg CBD co-dose can sometimes smooth the mental effects and lengthen relief without raising intoxication. This stacking is anecdotal but aligns with the complementary roles of THC, CBD, and terpenes.
Side effects are generally manageable: dry mouth, dry eyes, and occasional short-term memory lapses at higher doses. New patients should avoid driving or operating machinery and should consult a clinician if they are on interacting medications. Those prone to anxiety spikes at high THC levels should consider microdosing or pairing with CBD. Proper set, setting, and hydration improve outcomes in therapeutic contexts.
Comprehensive Cultivation Guide
Martian Kush is cooperative in the garden, with a moderate feeding appetite and strong resin production. Indoors, it thrives in temperatures of 24–28°C during lights on and 18–22°C at lights off, with 60–70% RH in early veg and 50–55% in late veg. In bloom, keep RH at 45–50% for weeks 1–5 and 40–45% for weeks 6–9 to mitigate botrytis risk on dense colas. Ideal VPD ranges from 0.9–1.2 kPa in veg and 1.2–1.5 kPa in flower.
Lighting intensity should build progressively, targeting 400–600 µmol/m²/s PPFD in veg and 900–1,200 µmol/m²/s in mid-to-late flower. Daily Light Integral (DLI) in veg around 30–40 mol/m²/day and 40–55 mol/m²/day in flower is appropriate for most phenos. Under LEDs, monitor leaf-surface temperature and consider a slight room temperature increase to maintain similar leaf temps as HPS. The strain responds well to far-red assisted end-of-day treatments for stretch management if equipment allows.
Martian Kush’s flowering time generally runs 63–70 days, with many cuts finishing around day 63–67. Expect 1.5×–2.0× stretch after the flip; topping at week 3–4 of veg and employing low-stress training produce a level canopy. Screen of Green (ScrOG) works well, and a single-layer trellis at week 2 of flower prevents cola flop later. Sea of Green (SoG) is also viable with smaller plants and short veg, given the cultivar’s cola-forward structure.
Feeding should be moderate and consistent. In soilless media, target EC 1.4–1.8 (700–900 ppm 0.5 scale) in mid flower, rising to EC 1.9–2.1 (950–1,050 ppm) for heavier phenos if leaves remain healthy. Maintain pH 5.8–6.2 in hydro/coco and 6.2–6.7 in soil. Ensure adequate calcium and magnesium, especially under LED, and balance sulfur to support terpene biosynthesis.
Organic approaches produce excellent results with Martian Kush. A living soil with well-mineralized amendments—kelp, neem, crustacean meal, basalt, and gypsum—paired with compost teas can deliver 1.5–2.5% total terpene content. Top-dress at transition and week 4, and avoid heavy nitrogen after week 4 of bloom to preserve flavor. Molasses or carbohydrate supplements are optional; the key is consistent moisture and healthy microbial activity.
Irrigation strategy should favor steady dry-backs rather than extremes. In coco, frequent small irrigations with 10–15% runoff help stabilize EC and reduce salt stress. In soil, water deeply but infrequently, letting the top 2–3 cm dry to prevent gnats while keeping the rhizosphere moist. Overwatering late can swell buds but risks botrytis on the densest colas.
Training and canopy management are straightforward. Remove lower third growth during week 2–3 of flower to improve airflow and push energy into tops. Selective leafing in week 3–5 improves light penetration; avoid aggressive defoliation late, which can stall resin development. Stakes or a second trellis layer may be needed if colas exceed 30–40 cm in length.
Pest and disease considerations mirror OG hybrids. The cultivar is not unusually susceptible, but dense tops necessitate vigilant IPM. Maintain strong airflow (0.5–1.0 m/s canopy-level), ensure regular horizontal air movement, and rotate safe preventatives in veg—neem alternatives, sulfur (veg only), and microbial sprays. In flower, rely on cultural controls, targeted beneficials, and spot treatments that preserve trichomes.
Yields under dialed indoor conditions commonly hit 450–550 g/m², with skilled growers pushing 600+ g/m² using CO2 enrichment at 1,000–1,200 ppm. Outdoors or in greenhouses, single plants can produce 500–900 g when trained and supported, depending on season length and latitude. The structure lends itself to hoop houses with light dep, finishing by late September to early October in many temperate zones. Wet climates require careful selection of the faster-finishing phenotype and proactive botrytis management.
Harvest timing benefits from both visual and quantitative cues. Check trichomes at multiple canopy levels; aim for mostly cloudy with 10–20% amber for balanced effects. Monitor volatilization risk by keeping late bloom temps under 27–28°C to preserve limonene and pinene. A staggered harvest—tops first, then lower sites after 3–5 days—can maximize ripeness and yield.
Drying and curing are critical to unlock Martian Kush’s aroma. Hang whole plants or large branches at 58–62% RH and 17–20°C with gentle airflow for 10–14 days. Once stems snap, trim and jar at 62% RH, burping daily for the first week, then weekly for weeks 2–4. Many growers report best flavor and smoothness between 4–8 weeks of cure, with terpene cohesion peaking around week 6.
Cloning success rates are high with standard techniques. Take 8–12 cm cuts from semi-woody growth, strip lower nodes, and root in 10–14 days in 21–24°C media. Aeroponic or peat-based plugs both work well; keep VPD lower in the first week to prevent wilt. Mothers stay manageable with regular pruning given the cultivar’s moderate internodal spacing.
Post-harvest, Martian Kush performs well in extraction. Hydrocarbon runs yield 18–25% from dried material, while fresh-frozen live resin can deliver expressive lemon-fuel sauce with 6–8% terp mass. For solventless, target 160–220 µm bags for flower rosin and 75–120 µm for hash rosin, depending on head size distribution. Gentle, low-temp presses preserve the citrus top notes and peppered gas finish.
Compliance and naming clarity matter for retailers and patients. While some markets reference “Purple Martian Kush (PMK)” as a nickname—an alias that has appeared alongside other strains on community sites—operators should verify genetics and avoid conflation. Listing Martian Kush as a DNA Genetics Seeds, mostly indica hybrid, with lineage Martian Mean Green × OG #18, supports transparency. This aligns with public strain directories that catalog Martian Kush among established cultivars.
