Written by Ad OpsOverview: Medellin Krack at a Glance
Medellin Krack is a modern hybrid bred by Puget Sound Seeds, a boutique breeder known for Pacific Northwest selections that favor vigor and terpene intensity. The strain carries a balanced indica/sativa heritage, presenting an adaptable profile that suits both daytime creativity and evening decompression. Growers note its robust structure and high trichome coverage, while consumers often highlight layered aromatics and a potent, clean finish. As a market-facing cultivar, it aims to deliver top-tier resin production with nuanced effects rather than a single-note punch.
While still relatively rare outside core connoisseur circles, Medellin Krack has developed a reputation for consistency across phenotypes. Early reports suggest a sweet-spicy nose overlaid with citrus and pine, backed by earthy undertones that hint at old-world genetics. Its naming evokes a high-energy city and intensity, but the effect profile tends to be balanced and controlled rather than chaotic. With careful cultivation, this strain can yield resin-drenched colas suitable for premium flower and solventless extraction.
For buyers and patients, the core appeal lies in the combination of a sophisticated terpene bouquet and assertive potency. THC-dominant chemotypes are common, with minor cannabinoids like CBG showing up in small but meaningful amounts. The strain's versatility enables different use cases: creative focus at low doses, steady mood lift at moderate doses, and heavier relaxation at higher doses. This flexibility has made it a favorite among small-batch producers seeking a reliable flagship hybrid.
History and Breeding Background
Puget Sound Seeds operates out of the U.S. Pacific Northwest, a region known for producing cultivars with stout disease resistance and terpene-forward profiles. Medellin Krack emerged from this environment, aiming to capture high resin output and multi-layered aromatics while retaining grower-friendly vigor. The breeder's approach typically emphasizes selection under variable humidity and temperature swings, a practical filter that translates well to home and commercial grows. As a result, Medellin Krack tends to tolerate suboptimal conditions better than fragile, showroom-only cuts.
The exact backstory reflects an era when breeders blended established workhorse lines with novel or less-documented parents to create unique profiles. Rather than lean fully into dessert terps or fuel-forward extremes, Medellin Krack appears to thread the needle between sweet, spice, and citrus, with a grounding earthy base. This balance aligns with Puget Sound Seeds' tendency to value functional effects as much as raw potency metrics. The result is a cultivar that feels modern yet not gimmicky, delivering familiar comfort with distinct twists.
Commercial availability has grown gradually, with most cuts circulating through clone swaps, small drops, and limited seed runs. The scarcity has kept the strain somewhat under the radar, but it also helped maintain line integrity by limiting uncontrolled outcrosses. In regions with mature markets, early batches have tested competitively against more famous hybrids, especially when grown under dialed environmental parameters. Its desirability increases when marketed for solventless or live rosin, where clean resin and terpene fidelity command premiums.
Genetic Lineage and Provenance
The lineage of Medellin Krack is best understood through breeder notes and third-party genealogy snapshots. According to a reputable genealogy aggregator, the strain appears as Medellin Krack (Puget Sound Seeds) connected to an Original Strains 'Unknown Strain' crossed with a Rhino parent. This is consistent with a listing pattern where Original Strains' Unknown Strain is a recurrent building block, and 'Rhino' is generally recognized in cannabis vernacular as a nod toward the White Rhino family. Source: Original Strains' Unknown Strain Lineage & Hybrids, which indexes 'Medellin Krack (Puget Sound Seeds) · Unknown Strain (Original Strains) x Rhino'.
This putative cross suggests an intentional blend of classic resin-heavy, possibly indica-leaning traits from Rhino with the wildcard contribution of an Unknown Strain. Rhino-descended lines are typically associated with dense flower structure, strong resin glands, and a firm body effect. The Unknown Strain component likely contributes variability in aroma and nuanced secondary terpenes, which matches user reports of citrus, spice, and mild pine layered over earth. Breeding hybrids of this type often aim to enhance both potency and terpene complexity without sacrificing yield.
It is important to acknowledge that the 'Unknown Strain' descriptor literally means the parental identity is not fully documented in public databases. In practice, breeders sometimes work with keeper cuts that were never formally named or were renamed for proprietary reasons. The presence of Rhino in the genealogy provides a compass for expectations around growth habit and resin, even if the other side of the parentage remains opaque. Growers should therefore phenotype with an open mind, expecting subtle differences in aroma expression among siblings.
From a practical standpoint, this genetic backdrop explains Medellin Krack's combination of sturdiness and sensory intrigue. The Rhino influence supports compact internodes, mechanical strength, and heavy trichome development, advantageous traits for both flower and hash production. The contribution from the Original Strains' Unknown Strain likely injects that brighter top-note terpene amplitude and a more balanced headspace. Together, they underpin a hybrid that reads contemporary but performs predictably in the garden.
Appearance and Morphology
Medellin Krack typically grows into a medium-stature plant with strong lateral branching and a Christmas-tree outline when untrained. Internodes run moderately tight, supporting dense, golf-ball to egg-shaped clusters that stack into spears by late bloom. Standard stretch after flip ranges from 1.6x to 2.0x, depending on light intensity and nitrogen taper. The canopy is easy to shape, and the plant responds predictably to topping and low-stress training.
Flowers present with thick calyxes and abundant capitate-stalked trichomes that frost bracts and sugar leaves. Under magnification, trichome heads often average 80–120 microns, a range sought after for solventless extraction. Mature buds display deep olive green hues with amber pistils, and colder nights may coax anthocyanin flashes along the edges. The bag appeal is emphatically 'sugar-coated', with a grainy, sandy resin feel when properly matured.
Leaf morphology skews hybrid, with medium-width leaflets that narrow as the plant transitions into mid-flower. Fan leaves maintain turgor well provided potassium and magnesium remain balanced from week three onward. Plants grown under high PPFD and adequate CO2 tend to stack tighter and produce thicker colas. In soil or soilless, the cultivar shows above-average tolerance for small pH swings, reducing the likelihood of tip burn when dialed correctly.
Aroma Profile
The dominant nose opens with a sweet-spice top note, often described as sugared citrus peel meeting mild black pepper. Underneath, a resinous pine thread weaves through a loamy, earthy base reminiscent of forest floor after rain. When flowers are burped during cure, a faint vanilla-herbal lift sometimes peeks through, especially in cooler-cured batches. Together, these layers make the jar crack experience dynamic rather than one-dimensional.
During late flower, agitation of live resin glands releases brighter limonene-forward tones that can read as lemon-lime with a twist of pith bitterness. Caryophyllene-driven spice is noticeable but not overwhelming, contributing warmth instead of bite. As the buds cure, the citrus softens and the earthy resin emerges more distinctly, creating a rounded bouquet. This evolution rewards patient curing of at least 21–28 days for maximum depth.
Grinding intensifies the pine and pepper, suggesting an active mix of alpha-pinene and beta-caryophyllene in synergy. Some phenotypes show a minty-cool tail on the exhale aroma, an indicator of minor amounts of borneol or eucalyptol, though these are typically trace. Across phenos, total terpene load often reads middle to high by nose, which aligns with observed resin density. The balance of sweet, citrus, spice, and earth makes it versatile for both flower appreciation and concentrate production.
Flavor Profile
On palate, Medellin Krack typically opens with candied citrus accented by a gentle pepper warmth. The mid-palate transitions into resinous pine and herbal earth, with a clean, slightly mineral edge on the finish. Vaporization at 180–190°C accentuates the sweeter top notes and preserves citrus clarity. Combustion leans the profile more toward spice and earth while maintaining a pleasant, waxy mouthfeel.
A properly cured batch delivers flavor persistence across multiple pulls, with the second and third draws often being the best. The retrohale brings an echo of black pepper and cedar, suggesting the caryophyllene-humulene tandem at work. Low-temperature dabs of rosin can reveal a brief vanilla-herb softness before the citrus-spice returns. Residual sweetness lingers without cloying, making the profile crowd-pleasing yet complex.
Water-cured or fast-dried samples tend to flatten the citrus and emphasize earth, underscoring the importance of a slow, cool dry. In contrast, a 60/60 dry and 62% RH cure expand the sweetness and lengthen the flavor arc. As with many hybrids, terpenes bloom when flowers are protected from light and excessive airflow during cure. Packaging in opaque, low-oxygen containers further helps preserve the top notes for retail presentation.
Cannabinoid Profile and Potency
Although published labs for Medellin Krack remain limited, its lineage and grower reports suggest a high-THC, low-CBD chemotype. In dialed indoor conditions, realistic THC ranges land between 18–26%, with elite phenotypes occasionally pushing the upper bound. CBD commonly tests below 1.0%, while CBG often appears in the 0.2–1.0% range. Total cannabinoids frequently measure 20–30% in well-grown batches, aligning with modern premium hybrid averages.
From a usage perspective, this potency band supports effects that arrive within minutes and peak by 30–45 minutes for inhalation. The headspace is typically clear and uplifted at lower doses under 10 mg THC equivalent, while 15–25 mg can introduce heavier body calm. Tolerance, set, and setting significantly influence subjective intensity, as with any high-THC cultivar. Consumers new to potent hybrids should titrate in 2–3 mg increments to identify their comfort zone.
For extractors, Medellin Krack's trichome density translates to respectable returns. Fresh frozen for hydrocarbon extraction may yield 18–24%, and well-selected phenos can produce 4–6% yield in solventless hash from dried material, with higher returns possible from fresh frozen heads. These figures vary with wash temperature, micron selection, and harvest timing, but they indicate resin that is both plentiful and mechanically cooperative. The presence of robust capitate-stalked heads improves separation efficiency and product clarity.
It is worth noting that environmental stressors can impact cannabinoid development by several percentage points. Light intensity, VPD, and harvest timing collectively influence the final profile more than any single factor. Harvesting at ~10–20% amber trichomes often balances head and body effects for this cultivar. Overripe trichomes may deepen sedation but risk terpene loss and a duller flavor.
Terpene Profile and Chemistry
Terpene expression in Medellin Krack is led by caryophyllene, limonene, and myrcene, with supporting roles from pinene and humulene. In composite profiles from similar hybrid lineages, total terpenes typically range 10–25 mg/g of flower, with caryophyllene at 2–5 mg/g, limonene at 1–3 mg/g, and myrcene at 3–7 mg/g. Alpha- and beta-pinene together often register 0.5–1.5 mg/g, while humulene lands around 0.5–1.5 mg/g as well. Minor contributors like linalool, ocimene, and terpinolene may register below 1 mg/g, depending on phenotype.
Caryophyllene imparts the warming pepper-spice and interacts with CB2 receptors, a feature associated with perceived body comfort in many users. Limonene contributes the citrus brightness and is frequently linked to ratings of mood elevation. Myrcene adds herbal-earth depth and can shape the perceived heaviness of the body effect when present at higher levels. Pinene and humulene round out the pine-wood and dry hop nuances, contributing to the strain's complex bouquet.
This terpene configuration suits Medellin Krack for both flower consumption and solventless extraction, where monoterpenes must be preserved through careful handling. Cold-chain processing helps retain limonene and pinene, which can volatilize easily during warm, oxidative exposure. A well-managed cure that avoids prolonged jar heat keeps total terpene losses lower, often within a 15–30% reduction from peak post-dry values. That range is typical across hybrids; careful workflow can push retention toward the low end of that loss band.
Growers interested in steering the profile can influence expression through light spectrum and nutrient strategy. Slightly higher blue light fractions in late veg can encourage tighter internodes and, anecdotally, brighter top-note terpenes. Adequate sulfur during weeks two to six of flower supports terpene synthase activity, which can be the difference between 'good' and 'memorable' aroma. Foliar essential oil products are not recommended in bloom, as they risk contamination and flavor distortion.
Experiential Effects
Medellin Krack generally delivers a clear, uplifted onset that transitions into a grounded, relaxing body feel. The headspace often features gentle euphoria and task-friendly focus in the first 30–60 minutes at modest doses. Over time, the body effect becomes more present, smoothing tension without flattening motivation. Users often describe the arc as steady and composed rather than jagged or racy.
At higher inhaled doses, sedation can emerge, especially in phenotypes with heavier myrcene expression. In social contexts, the strain tends to support a relaxed, conversational mood with low mental clutter. For creative tasks, lower doses can unlock flow without the distraction sometimes associated with strong limonene-led cultivars. Music, visual work, and light outdoors activity pair particularly well during the mid-phase of effects.
Common side effects mirror those reported across high-THC hybrids: dry mouth and dry eyes are the most frequent, with occasional lightheadedness if consumed rapidly. Anxiety or overstimulation are reported less commonly but can occur in sensitive users or at very high doses. Spacing sessions, hydrating, and pairing with food can reduce adverse experiences. The typical effect duration for inhaled flower is 2–3 hours, with the peak in the first hour.
Potential Medical Uses
Given its likely cannabinoid and terpene balance, Medellin Krack may appeal to patients seeking mood elevation with manageable body relief. Caryophyllene's CB2 activity, combined with limonene's mood-brightening potential, maps to anecdotal use for stress modulation and daily-function support. Myrcene and humulene may add perceived body ease without overwhelming sedation when dosing is conservative. This balance can make the strain suitable for late afternoon or early evening symptom management.
In patient reports for similar chemotypes, potential areas of interest include stress-related tension, transient insomnia, appetite support, and general discomfort. For sleep, the strain may help with sleep latency at moderate to higher doses, particularly if harvested at slightly more mature trichome levels. For daytime use, microdosing can retain clarity while easing background irritability. As always, individual response varies and should guide dosing decisions.
Because CBD content is typically low, those seeking anxiety relief without intoxication might consider pairing Medellin Krack with a CBD-dominant preparation. Ratios like 1:1 or 2:1 CBD:THC can blunt overstimulation and broaden the therapeutic window. Patients new to THC should begin with very small inhaled amounts and wait several minutes before redosing. Medical decisions should be made in consultation with a qualified clinician, especially when other medications are in play.
Comprehensive Cultivation Guide: Environment, Media, Nutrition
Medellin Krack performs well in controlled indoor environments and protected outdoor/greenhouse scenarios. Ideal daytime temperatures are 24–28°C in veg and 22–26°C in flower, with nights 18–21°C. Target relative humidity is 60–70% in veg, tapering to 45–55% in early flower and 40–50% in late flower. Recommended VPD ranges are 0.8–1.2 kPa in veg and 1.2–1.6 kPa in bloom to balance transpiration and pathogen suppression.
Lighting targets should sit around 400–600 µmol/m²/s PPFD in veg and 800–1000 µmol/m²/s in flower. With supplemental CO2 at 1000–1200 ppm, plants can utilize up to 1200–1400 µmol/m²/s PPFD in late bloom if nutrients and irrigation are tuned. Photoperiod is standard 18/6 for veg and 12/12 for bloom, with a typical stretch of 1.6x–2.0x after flip. Blue-heavy spectra in late veg promote tighter stacking, while red-heavy spectra in late bloom can aid bulking.
In soil, aim for a pH of 6.2–6.5; in coco/hydro, 5.8–6.0 is optimal. EC/ppm targets are 1.2–1.6 EC in veg and 1.6–2.2 EC in bloom, tapering nitrogen after week three of flower. A general NPK approach that works well is roughly 3-1-2 in veg, shifting to 1-2-2 in early bloom and 0-3-3 in late bloom. Maintain calcium in the 150–200 ppm range and magnesium 50–70 ppm to prevent mid-bloom deficiencies.
Irrigation frequency depends on media and root mass, but Medellin Krack likes rhythmic wet-dry cycles that avoid prolonged saturation. In coco/perlite at 30–40% perlite, multiple small irrigations per photoperiod can stabilize EC and oxygenate roots. In living soil, top-dressing with balanced dry amendments and adding compost teas during early flower can keep microbial activity high. Avoid heavy foliar sprays after week two of bloom to protect resin and prevent microbe overload.
Cultivation Guide Continued: Training, Flowering, Harvest, and Post-Harvest
Structural training is straightforward: top once or twice in veg, then apply low-stress training to spread the canopy. Medellin Krack fills a 4x4 ft tent efficiently with two to four plants and supportive trellising. A single-layer SCROG can even out colas and limit larf, improving both yield and trim time. Defoliation works best when done lightly at week three and a touch-up at week six, avoiding stress spikes.
Flowering time typically runs 56–63 days indoors, with some phenotypes preferring 63–70 days for maximum terpene maturity. Outdoor harvest in temperate zones often lands late September to early October, depending on latitude. The cultivar handles modest late-season chill, but persistent wet conditions warrant aggressive airflow and preventive IPM. Watch for powdery mildew in high humidity and ensure adequate leaf surface dry-down each cycle.
Trichome maturity is best judged with a loupe: harvest around 5–10% amber for a brighter, functional effect, or 15–25% amber for a heavier finish. Pre-harvest flushing for 7–10 days in inert media can improve burn quality and ash color; living soil systems may require only water and microbial teas. Wet trimming preserves trichomes but risks terpene loss if drying is too rapid; dry trimming is slower but often protects top notes. Choose the method that best matches your drying environment control.
Dry at approximately 60°F (15.5–16.5°C) and 60% RH for 10–14 days with gentle air exchange. Target an end moisture of 10–12% or a water activity of ~0.58–0.62 aw before jarring. Cure at 62% RH in opaque containers, burping daily for the first week, then weekly for 3–4 weeks. Properly cured Medellin Krack maintains bright citrus-spice for months with minimal degradation.
Yield, Phenotype Selection, and Quality Control
Indoor yields of Medellin Krack average 450–600 g/m² under high-efficiency LEDs, with experienced growers occasionally exceeding 600 g/m². Outdoor plants in rich soil and full sun can return 400–800 g per plant, contingent on canopy size and season length. Rosin makers often select phenotypes with sandy resin and 80–120 micron-dominant heads for 4–6% dry yields or higher on fresh frozen. Colas are dense, so airflow and spacing are crucial to avoid microclimate issues.
When hunting phenotypes from seed, prioritize plants that maintain citrus-spice balance without losing earth-pine depth. Visual cues include early frosting by week four, strong lateral branching, and uniform bud set along laterals. A keeper cut will typically dry and cure into a consistent flavor arc across jars, with minimal variance. Test small harvest windows at day 58, 63, and 67 to pinpoint the optimal expression for your environment.
Quality control starts in the canopy: maintain even light distribution and monitor leaf surface temperature, not just ambient air. Use infrared thermometers to keep LST within 1–2°C of air temp, preventing hidden heat stress that bleaches terpenes. After harvest, document dry rate, jar RH, and aroma changes at each stage to refine SOPs. A data-driven workflow consistently reproduces top-shelf results and supports marketing claims with real metrics.
