Trunk77 is an indica-leaning cannabis cultivar bred by Kokua Seed, a breeder noted by enthusiasts for carefully selected, robust seed lines. As the name implies, this strain is known for building stout, trunk-like stems and a compact frame that thrives in a variety of grow environments. With a heritage that is mostly indica, Trunk77 is engineered for stability, density, and consistent structure in the garden.
While public lab data on this specific cultivar remains limited, Trunk77 has quickly developed a reputation among growers and connoisseurs for resin-rich flowers and a grounded, woody aroma profile. It presents the kind of calm, body-focused experience that indica fans often seek, yet it retains enough uplift to avoid feeling heavy at moderate doses. For consumers seeking a controllable evening strain and growers who prioritize manageable canopies, Trunk77 offers a compelling blend of traits.
The following guide assembles what is known and what can be reliably inferred from its indica-dominant architecture, with careful attention to grower-reported outcomes and general market data for similar chemotypes. Where specific lab results are sparse, ranges are based on common test results for indica-dominant cultivars in legal markets. That approach gives both patients and cultivators realistic expectations while highlighting the areas where fresh, local testing should still inform decisions.
Breeding History and Context
Kokua Seed bred Trunk77 with a clear emphasis on indica-dominant structure and reliability. Indica-leaning cultivars are frequently chosen for their shorter flowering times, denser buds, and tractable training response, all of which align with the observed behavior of Trunk77. In practical terms, that means plants that perform well indoors under moderate ceiling heights and respond consistently to topping or screen-of-green techniques.
The 77 in its name strongly suggests a breeder phenotype code, a standard practice in cannabis where number tags differentiate standout selections from large seed hunts. In many breeding programs, phenotypes are evaluated for stem girth, node spacing, resin coverage, and resistance to stressors like heat or inconsistent feeding. A keeper pheno labeled 77 indicates this expression excelled on multiple criteria before being stabilized and released.
Although Kokua Seed has not broadly publicized an exact cross for Trunk77, the cultivar behaves like a modern indica with a hint of hybrid vigor. That typically means a stretch factor of around 1.3x to 1.7x after flip, rather than the 2x or greater stretch associated with many sativas. For cultivators, this history translates into predictability in canopy management and harvest timing.
Genetic Lineage and Phenotypic Foundations
Because the exact parentage has not been publicly detailed, lineage analysis relies on morphology, terpene tendencies, and garden performance. Trunk77 shows hallmark indica features such as broad leaflets, stout branching, and a high calyx-to-leaf ratio in later flower. These traits often trace to Afghani, Hindu Kush, or similarly landrace-influenced lines that have been modernized for potency and bag appeal.
The plant’s ability to stack dense colas with minimal internodal gaps suggests selection for hard, uniform buds. This is a priority in modern breeding because it protects yield density while facilitating straightforward trimming, especially with the aid of light defoliation late in stretch. The cultivar’s steady response to training also implies heterosis from at least one hybrid parent, even if the majority of its genetic expression is indica.
On the chemotype side, indica-dominant lines commonly express terpene suites led by myrcene, beta-caryophyllene, and limonene or linalool. That pattern dovetails with reported aromas from Trunk77 that lean woody, earthy, peppery, and faintly citrus. Chemovars in this lane tend to produce THC-dominant cannabinoid profiles with minor support from CBG and trace CBC.
Appearance and Morphology
Visually, Trunk77 tends to produce medium-height plants with a sturdy central stem and symmetrical, lateral branches. Indoors with standard training, final height often lands around 80 to 130 centimeters, with vegetative times of 3 to 5 weeks. In open soil or large outdoor containers, plants can reach 150 to 200 centimeters if given a longer vegetative period and ample root volume.
Leaves are broad, deep green, and capable of expressing dark, glossy tones when nitrogen and magnesium are balanced. During late flower, bracts swell to form dense, rounded colas with a tight calyx structure, favoring weight retention and a visually appealing finish. Under strong light, resin heads often appear thick and cloudy even before peak ripeness, signaling a high glandular density.
Trichome coverage is typically above average, giving the buds a sugar-frosted look that reads as premium even before cure. Resin adherence makes the cultivar a candidate for hand-trimmed top colas and machine-assisted trim of lower popcorn without excessive loss. Expect orange to amber pistils to weave through a forest-green base, with occasional anthocyanin expressions in cooler night temperatures.
Aroma and Scent Profile
Trunk77 opens with a woody and earthy core that many describe as cedar chest, fresh sawdust, or seasoned oak. Underneath this foundation sits a hashy, peppered spice that hints at beta-caryophyllene dominance. Subtler layers of citrus peel, faint pine, and a whisper of dried herb or thyme emerge as the flower warms or is broken apart.
During fresh grind, the nose typically intensifies toward a forest-floor bouquet with a slightly sweet edge. This progression often signals a myrcene-rich profile augmented by small amounts of limonene and humulene, which together read as both grounded and bright. Consumers who prefer terpene complexity over overt dessert notes will find the aromatic structure confidently classic rather than confectionary.
Post-cure, the bouquet usually stabilizes into a consistent woody-spiced signature. Properly dried and cured flower should register minimal chlorophyll bite, keeping the peppered wood notes clean rather than acrid. Jar burps during the first two weeks of cure commonly reveal the citrus peel accent, a desirable sign of preserved monoterpenes.
Flavor and Mouthfeel
On the palate, Trunk77 mirrors its aroma with a dominant wood-and-earth flavor accented by black pepper and a light citrus exhale. The first draw is typically smooth if properly cured, with a low-grit mouthfeel that avoids harshness even at higher temperatures. A faint resin sweetness lingers after the finish, particularly noticeable in glass or clean ceramic devices.
Combustion brings forward the earthiness and pepper, while vaporization accentuates the brighter citrus and herbal edges. Between 175 and 185 degrees Celsius in a dry herb vaporizer, many users report a balanced terp expression with less throat tickle. At slightly higher temps, the wood-spice bass notes deepen, which some connoisseurs prefer for nighttime sessions.
Edibles or concentrates made from Trunk77 often carry over the same peppered wood signature, though confectioners can mask it with cocoa, molasses, or citrus formats. In hash rosin form, the finish tends to lengthen, with a lingering cedar-pepper tone that pairs well with herbal teas. Overall, the flavor experience is traditional and refined, favoring depth over sweetness.
Cannabinoid Profile and Potency
Third-party, publicly accessible lab data specific to Trunk77 remains limited as of 2025, but indica-dominant cultivars in mature markets frequently test in the 18 to 24 percent THC range. Some elite phenotypes and dialed-in grows can reach 25 to 28 percent THC, though these are outliers rather than guaranteed benchmarks. CBD content is typically low in such chemotypes, commonly below 1 percent, with total cannabinoids around 20 to 30 percent when minor cannabinoids are included.
CBG often appears as a minor player, usually between 0.2 and 0.8 percent, and CBC is frequently detectable in trace amounts under 0.2 percent. Total terpene content in well-grown indica-leaning flowers tends to land near 1.5 to 2.5 percent by weight, with top-shelf batches occasionally surpassing 3 percent. Because terpenes modulate perceived potency and onset, Trunk77’s strong terp backbone may make its effects feel more pronounced than THC alone suggests.
From a consumer perspective, potency perception is highly variable and influenced by tolerance, consumption method, and set and setting. Inhalation typically delivers onset within 5 to 10 minutes, with a 2 to 4 hour duration, while edibles require 30 to 90 minutes to onset and can last 4 to 8 hours. New consumers should titrate slowly, starting low and spacing sessions to observe cumulative effects.
Terpene Profile and Volatile Chemistry
Trunk77’s aromatic profile suggests a terpene stack led by myrcene and beta-caryophyllene, with supporting roles from limonene, humulene, and possibly linalool. In similar indica-dominant cultivars, myrcene often exceeds 0.5 percent by weight, with total caryophyllene near 0.3 to 0.6 percent and limonene around 0.2 to 0.5 percent. These values can swing meaningfully with environment, cure, and phenotype, which is why fresh, local lab reports remain the gold standard.
Myrcene contributes to the earthy, musky foundation and is frequently associated with body relaxation. Beta-caryophyllene, a dietary terpene that can interact with CB2 receptors, adds the peppered spice and may complement anti-inflammatory effects. Limonene often explains the citrus zest lift, while humulene can overlay a dry, woody bitterness that reads as cedar or hops.
Total terpene percentage is a practical marker for aroma intensity and flavor persistence. In consumer experience, flower over 2 percent total terpenes often presents as notably aromatic, while sub-1 percent material can seem muted even at similar THC levels. For growers, curing practices that protect monoterpenes are critical, as myrcene and limonene are among the most volatile and can rapidly flash off under warm, dry conditions.
Experiential Effects and Onset
As a mostly indica strain, Trunk77 typically delivers a calm body effect with a steady, centered mental tone. At moderate doses, users often report tension relief, gentle mood elevation, and a clear arc from initial uplift to later relaxation. At higher doses, couch-lock becomes more likely, along with a heavier eyelid effect that many turn to for sleep support.
Inhaled, the onset is rapid, commonly within 5 to 10 minutes, peaking around 30 to 45 minutes, and tapering over 2 to 4 hours. Vaporized consumption can feel slightly brighter and more cerebral during the first 20 minutes, with the body load building as the session progresses. Edibles pivot the profile toward a longer, more immersive body experience with a slower decline.
Common side effects include dry mouth, dry eyes, and occasional orthostatic dizziness, especially in dehydrated or naïve users. Anxiety is less frequently reported with indica-dominant cultivars but can occur when doses overshoot comfort levels or when consumed in stimulating settings. As always, set, setting, and dose titration strongly influence outcomes, with many users finding optimal relief in small to medium inhaled doses.
Potential Medical Uses and Evidence
The indica-leaning physiology of Trunk77, paired with likely myrcene and beta-caryophyllene leadership, positions it as a candidate for pain modulation, muscle tension, and sleep initiation. The 2017 National Academies review found substantial evidence that cannabis is effective for chronic pain in adults, though individual responses vary and product chemotypes matter. For sleep, multiple observational studies report improved sleep scores among medical cannabis patients, with some surveys indicating 60 to 70 percent of respondents notice better sleep when using THC-dominant products.
Beta-caryophyllene is notable for CB2 receptor activity, which research associates with potential anti-inflammatory effects in preclinical models. Myrcene demonstrates potential analgesic and sedative properties in animal studies, aligning with user reports of body relaxation and reduced restlessness. While these mechanisms are promising, clinical outcomes depend on dosage, route, and the full matrix of constituents beyond the headline cannabinoids.
For anxiety and mood symptoms, outcomes can be mixed and dose sensitive. Low to moderate THC may ease anxiety for some, while high THC can increase it; limonene and linalool sometimes temper this response, which is why balanced terpene content helps. Patients should consult clinicians familiar with cannabinoid therapy, start with low doses, and monitor interactions with other medications, especially sedatives and antidepressants.
In inflammatory conditions, some patients report relief with THC-dominant strains that feature caryophyllene and humulene; however, evidence remains preliminary outside of pain. Muscle spasticity and neuropathic pain are additional areas where THC-led profiles sometimes help, supported by patient registries that show these diagnoses among common qualifying conditions. Because individual variability is high, documenting responses with simple symptom scales can help patients and providers fine-tune timing and dose.
Comprehensive Cultivation Guide: Environment, Training, and Nutrition
Trunk77’s mostly indica heritage makes it well-suited to indoor and greenhouse cultivation with moderate ceilings. Aim for daytime temperatures of 22 to 26 degrees Celsius and nighttime drops of 2 to 4 degrees to preserve color and terpene integrity. Relative humidity should sit around 55 to 65 percent in vegetative growth, tapering to 45 to 50 percent in early flower and 40 to 45 percent in late flower to reduce Botrytis risk.
Light intensity targets are straightforward for a sturdy indica. In vegetative growth, 400 to 600 PPFD with a daily light integral around 20 to 30 mol per square meter per day establishes dense internodes. In flower, step up to 900 to 1200 PPFD with a DLI of 35 to 50 mol per square meter per day, increasing CO2 to 800 to 1200 ppm if the environment is sealed and temperatures run on the warmer side.
Trunk77 handles topping and screen-of-green very well due to its naturally thick stems. Top once at the fifth or sixth node to encourage lateral branching, then set a trellis and tuck through the first two weeks of stretch for an even canopy. Low-stress training on the outer branches helps prevent apical dominance and encourages uniform cola development without excessive defoliation.
Nutrient programs can be conventional salts or living soil, provided calcium and magnesium are not neglected. In coco or hydro, target pH 5.8 to 6.2 with EC around 1.4 to 1.8 mS per centimeter in late veg and 1.8 to 2.2 mS per centimeter mid-flower. In soil, aim for pH 6.2 to 6.8 with a balanced NPK that transitions from nitrogen-forward in veg to phosphorus and potassium-forward in bloom, including supplemental Ca, Mg, and Si for stem strength.
A typical feeding rhythm includes nitrogen at 120 to 180 ppm in veg and a gradual taper after flip, with potassium rising to 200 to 280 ppm during peak flower. Bud density responds well to adequate potassium and sulfur, but overfeeding can harden the smoke and suppress aroma. Monitor runoff EC and leaf tips for early signs of excess, and maintain a gentle irrigation cadence that promotes wet-dry balance without drought stress.
Vapor pressure deficit management helps Trunk77 express resin and avoid microclimate issues. Keep VPD near 0.8 to 1.1 kilopascals in veg and 1.2 to 1.5 kilopascals in flower, adjusting with small fan speed increases and dehumidification as needed. Good airflow beneath the canopy is essential, as indica colas can become tightly packed and humidity prone.
