Moby Dick emerged during the 2000s wave of high-potency, sativa-leaning hybrids that prioritized yield and energy over couch-lock. Within that surge, Green House Seeds’ Moby Dick quickly rose to prominence thanks to its sky-high potency and substantial harvest potential. Contemporary seed catalogues routinely highlighted it as a heavy producer that could keep up with go-getters, reflecting its Haze-forward personality and brisk, buzzy high.
The strain’s name nods to Herman Melville’s leviathan, a fitting metaphor for a cultivar known to become massive in both stature and output. Seed marketplaces frequently place it in “high-yield” categories, and its reputation for abundance became a key reason growers sought it out. As its popularity grew, multiple seed banks released their own selected versions and autos, helping the name achieve global familiarity.
By the mid-2010s, Moby Dick’s reputation had expanded beyond harvest size to include potency metrics reported well into the 20%+ THC range. Autoflower variants commonly list THC as “high,” often in the 15–20% band, giving new growers a shorter-cycle entry point with considerable strength. That combination of power, speed (for autos), and volume ensured Moby Dick stayed on “top lists,” including compilations of strains noted for minimal munchies and energizing daytime value.
Today, Moby Dick remains a fixture in sativa-dominant collections from leading European breeders. Green House Seeds’ branding around this strain helped cement its global status, while other seed houses such as Barney’s Farm also distribute popular versions. Across regions, the name consistently signifies a vigorous plant with tall stature, large colas, and a bright, Haze-style ride.
Genetic Lineage and Breeding
Moby Dick is generally described as a sativa-dominant hybrid with strong Haze influence and a White Widow-adjacent backbone. The “Haze” component explains its cerebral spark and long-legged stretch, while the Widow family ties are implicated in resin density and hard, heavy blossoms. This hybridization strategy aimed to merge classic heady stimulation with the dense trichome load and reliability of mid-1990s European champions.
While phenotypic expressions vary by breeder and lot, the throughline is a sativa-majority heritage. Many seed banks summarize it as a 60–80% sativa profile, and growers routinely report internode spacing characteristic of Haze lines. Notably, seed-bank commentary often name-checks White Widow when describing the family tree, underscoring Moby Dick’s resin-forward morphology.
The success of the original photoperiod formula led to a wave of derivatives, including autoflower versions and crosses like Moby Dick x Do-Si-Dos. Autoflower expressions typically carry a more compact frame and earlier finish, with THC commonly posted at 15–20%. Photoperiod versions remain the yield kings, with indoor figures routinely quoted above 600 g/m² in optimized conditions.
Breeding objectives across vendors converge on three pillars: vigorous stretch for canopy fill, improved resin production from Widow lineage, and citrus-wood aromatics consistent with Haze-forward terpenes. Selection pressures favor phenotypes that tolerate training and high-intensity lighting while resisting mold on bulky colas. These goals explain why Moby Dick is so often recommended for ScrOG and high-output rooms.
Appearance and Bud Structure
Moby Dick plants typically present a tall, lanky sativa frame with substantial internodal spacing in early veg. Under high-intensity lighting and adequate root volume, it can double or even triple in height during the first 2–3 weeks of flower. Indoor growers frequently cap height with topping, LST, and ScrOG to create a broad, uniform canopy of spears.
Buds are dense for a sativa-dominant cultivar, forming tapered colas that stack into long, weighty towers. The White Widow connection shows up in the heavy trichome coverage, giving mature flowers a sugar-frosted appearance. Calyxes swell generously by week 8–10 of bloom, consolidating into firm, resin-glazed clusters with relatively sparse but wiry pistils.
Coloration ranges from lime to forest green, with occasional lime-lavender hues in cooler night temperatures. Fan leaves are typically narrow and jagged, consistent with sativa heritage, and they may require regular defoliation to improve airflow. During late bloom, resin glands become abundant enough to form a visible sheen on sugar leaves, making trimming sticky but rewarding.
Because colas can get very dense, growers often space branches and increase airflow to prevent moisture buildup. Proper trellising or plant yoyos are recommended once flowers pass the mid-bloom bulking phase. On a scale of 1–10, bud density is often reported around 7–8 for high-grade phenotypes, contributing directly to the cultivar’s yield reputation.
Aroma Profile
Aromatically, Moby Dick leans bright and brisk, with a lemon-citron top note that announces its Haze lineage. Many growers and consumers also report cedarwood and light pine undertones, especially in well-cured batches. This lemon-and-wood interplay is common in seed-bank notes, and it tracks with terpene profiles that often feature terpinolene, limonene, and α-pinene.
On the vine, early bloom can smell slightly herbal and green, evolving into sharper citrus by mid-flower. By the end of curing, the bouquet rounds out into zesty lemon peel with a dry, cedary backbone and a hint of spice. Some batches emit a faint floral sweetness, reminiscent of orange blossom or verbena, especially when limonene and linalool are elevated.
A minority of reports describe flatter aromas when plants are harvested early or cured poorly. One consumer note even characterized a sample as “paper-like,” underscoring how post-harvest technique strongly influences scent. Optimal curing—60–62% RH for 3–5 weeks—usually restores the citrus-wood luster and keeps green-grassy volatiles at bay.
Flavor Profile
The flavor tracks the aroma closely, leading with lemon zest, sweet citrus oil, and dry cedar. On the inhale, expect a high-note sparkle that feels clean and almost effervescent when vaporized at 175–185°C. On combustion, a touch of spice and pine emerges, while the exhale often leaves a woody, lemon-peel aftertaste.
Terp preservation benefits from a gentle dry and a slow cure; rapid drying can mute the top notes and accentuate bitterness. In well-cured examples, limonene-driven citrus remains intact for weeks, with pinene contributing a crisp, resinous edge. The cedar nuance intensifies as jars “mature,” giving the flavor a slightly aged, classic character.
Phenotypic variance means some jars skew toward pine-herbal rather than overt lemon. Rare outliers can taste bland if harvested prematurely or overdried, aligning with scattered “paper-like” impressions. To maximize flavor, aim for a final moisture content near 10–12% by weight and keep curing temps around 18–21°C.
Cannabinoid Profile
Moby Dick is widely regarded as a high-THC cultivar, with photoperiod expressions frequently reported in the 18–26% THC range. Select elite cuts and some breeder claims have cited upper-20s THC in exceptional runs, though results vary by environment and lab protocols. Autoflower versions typically list 15–20% THC, offering substantial potency within a shorter timeline.
CBD content is generally low, commonly below 0.5–1.0% in standard phenotypes. Minor cannabinoids such as CBG tend to appear in the 0.2–1.0% band, while THCV often registers as trace to low but can spike modestly in Haze-leaning plants. Total cannabinoids for premium indoor harvests typically land between 20–30% by dry weight when THC is dominant and CBD is minimal.
Extracts and rosin from Moby Dick can concentrate THC and terpenes substantially, with rosin often testing 65–80% total cannabinoids depending on press temperature and source material. Yields for ice water hash from well-grown flowers commonly range from 3–5% by weight of dried input, reflecting the cultivar’s strong resin coverage. These stats reinforce the strain’s reputation as both a top-shelf flower and a viable extraction feedstock.
It’s important to note that cannabinoid outcomes are highly environment- and phenotype-dependent. Grow conditions—light intensity (PPFD 700–1000), VPD (1.1–1.3 kPa in mid-late bloom), and nutrient balance—can swing results by several percentage points. Lab variance and post-harvest handling also influence readings, so reported numbers should be treated as ranges rather than guarantees.
Terpene Profile
Moby Dick’s terpene profile is typically sativa-forward, with terpinolene, limonene, and α-pinene frequently reported as headliners. Total terpene content in well-grown indoor batches often falls between 1.5–3.0% by dry weight. Caryophyllene and myrcene commonly appear as secondary contributors, rounding out the bouquet with peppery and herbal warmth.
A representative profile might show terpinolene at 0.3–0.8%, limonene at 0.2–0.7%, and α-pinene at 0.2–0.6%. Caryophyllene often lands between 0.1–0.4%, with myrcene in a similar range depending on the phenotype. Linalool and ocimene occasionally add trace floral and sweet-green highlights.
These terpenes map cleanly onto the sensory notes: limonene for lemon-zest brightness, pinene for resinous pine and perceived mental clarity, and terpinolene for zesty, herbal lift. Caryophyllene can add a dry, woody spice that aligns with the cedar motif repeatedly mentioned by vendors. Myrcene’s role varies; in many sativa-leaners it remains modest, helping prevent the flavor from slipping into overly musky territory.
Growing practices strongly influence terp expression. Gentle drying (10–14 days at 18–21°C, 55–60% RH) and a slow cure preserve volatile monoterpenes that give Moby Dick its high-tone sparkle. Overly warm dries or rough trimming can slash monoterpene retention by 30–50%, dulling the lemon-cedar signature.
Experiential Effects
Consumers commonly describe Moby Dick as energizing, clear, and drive-friendly in the first phase, with a buzzy, motivational lift. Onset is brisk for inhalation, often within 2–5 minutes, with a peak around 30–45 minutes. Many users report a functional focus window suited to tasks, creative work, or social activity.
As the session progresses, the intensity can climb, reflecting its high-THC ceiling and sativa tilt. In higher doses, effects may transition from crisp concentration to a more panoramic, heady experience with heightened sensory detail. Duration averages 2–3 hours for inhalation, with a longer tail in edibles made from the strain.
Physical effects are lighter than indica-heavy cultivars, usually presenting minimal body sedation. Notably, some roundups of “no-munchies” strains include Moby Dick, suggesting that appetite stimulation may be lower than expected for such a potent THC variety. Individual differences are significant, but many daytime users specifically call out reduced snack cravings compared with sweeter, myrcene-led cultivars.
Side effects can include dry mouth, dry eyes, and—at higher doses—transient anxiety or racing thoughts. Novices are best served by conservative titration, especially with strong photoperiod batches above 20% THC. A comfortable set and setting, hydration, and clear intentions help keep the experience sharp and productive.
Potential Medical Uses
The energizing, sativa-leaning character of Moby Dick may appeal to patients seeking daytime symptom relief without heavy sedation. Anecdotal reports highlight potential support for fatigue, low motivation, and mood dips, aligning with the strain’s brisk onset and upbeat arc. For some, the cultivar’s focus-friendly initial phase may aid concentration on tasks or creative pursuits.
Although THC is usually associated with increased appetite, Moby Dick appears in multiple lists of strains that don’t drive intense munchies. Individuals aiming to avoid appetite spikes may find this profile helpful compared to high-myrcene, dessert-style cultivars. However, responses vary widely, and medical users should monitor personal outcomes closely.
Pain relief from THC and caryophyllene may offer short-term comfort for mild to moderate aches, though this strain is not typically selected for deep body sedation. The lower CBD profile suggests it may pair well with a CBD-rich companion strain for those seeking anxiety dampening or inflammatory support. Vaporizing at lower temps (175–185°C) can maintain clarity while still providing relief.
As with all cannabis-based interventions, dosing strategy and timing matter. Patients sensitive to THC should consider microdoses (1–2 mg THC inhaled or 1–2.5 mg oral) and gradually titrate. Medical guidance from a clinician experienced in cannabinoid therapy is recommended for integrating Moby Dick into a comprehensive plan.
Comprehensive Cultivation Guide
Overview and Growth Habit: Moby Dick is a vigorous, sativa-dominant hybrid known for rapid vertical growth and substantial yields. Indoors, a 4–6 week veg can produce plants that easily triple in height after flip if untrained. Most growers implement topping, low-stress training (LST), and ScrOG to manage canopy height and maximize light capture.
Flowering time commonly falls between 9–11 weeks for photoperiod versions, with many finishing around the 65–75 day mark. Autoflower variants shorten the total cycle to roughly 10–12 weeks seed-to-harvest. Target indoor yields of 600–750 g/m² are achievable under optimized conditions; outdoors, 800–1500 g/plant is realistic in long, sunny seasons.
Environment and Lighting: In veg, aim for 24–28°C daytime and 18–22°C nighttime temperatures with 60–70% RH and a VPD near 0.8–1.0 kPa. Flowering thrives at 22–26°C days, 18–21°C nights, 45–55% RH in early-mid bloom, and 40–50% RH in late bloom, with VPD around 1.1–1.3 kPa. Provide PPFD of 600–900 µmol/m²/s in early flower and up to 900–1100 µmol/m²/s for strong phenotypes if CO₂ is 800–1200 ppm.
Photoperiods of 18/6 in veg and 12/12 in flower are standard; autos run well at 18–20 hours of light throughout. Daily Light Integral (DLI) targets of 35–50 mol/m²/day in flower help maximize yields without overshooting plant metabolism. Keep canopy distance appropriate for your fixture to avoid light burn on tall tops.
Substrate and Containers: Moby Dick responds well to high-oxygen root zones. In soil, use a well-aerated mix (30–40% perlite or equivalent), and consider 11–18 L (3–5 gal) pots for mid-size indoor plants. In coco or hydro, growth accelerates; 12–16 L containers or recirculating systems can support large canopies.
Nutrition and EC/PPM: This cultivar is a sturdy feeder. In soil, aim for EC 1.4–1.8 in veg and 1.8–2.2 in peak bloom, watching for tip burn as a ceiling. In coco/hydro, many growers successfully push EC 2.0–2.4 in mid-late bloom if environmental parameters are dialed and runoff EC remains stable.
Maintain pH at 6.2–6.7 in soil and 5.7–6.2 in coco/hydro to optimize nutrient uptake. Cal-Mag support is often beneficial under high-intensity LEDs, especially during weeks 2–6 of flower. Nitrogen should taper after week 3 of bloom while phosphorus and potassium increase to support bud bulking.
Training and Canopy Management: Topping once or twice at nodes 4–6 encourages multiple mains and moderates vertical surge. LST and ScrOG create a uniform plane, essential for even light distribution on this long-stretch strain. Defoliation at pre-flip and again around day 21 can open airflow and light penetration; avoid over-stripping to prevent stress.
Because Moby Dick’s colas can get dense, allocate 20–30 cm between vertical branches and maintain strong horizontal airflow. Oscillating fans above and below the canopy reduce microclimates that foster botrytis. Trellis support (two layers 20–30 cm apart) helps keep heavy spears upright late in bloom.
Irrigation Strategy: In soil, water when pots reach 50–60% of saturated weight to maintain wet-dry cycling. In coco/hydro, higher-frequency fertigation (1–3 times daily) at 10–20% runoff stabilizes EC and prevents salt buildup. Monitor runoff EC/PPM and adjust feed strength if drift exceeds 10–15% of input.
Integrated Pest Management (IPM): Dense flowers and large canopies benefit from preventive IPM. Employ weekly scouting, sticky traps, and cleanliness to deter fungus gnats, thrips, and spider mites. Biologicals like Bacillus subtilis and Beauveria bassiana, along with sulfur in veg (not in flower), can prevent powdery mildew in humid climates.
Aroma Control and Post-Harvest: While not the loudest strain on earth, lemon-cedar terpenes are noticeable; a properly-sized carbon filter is recommended. Dry for 10–14 days at 18–21°C and 55–60% RH with gentle airflow. Cure in airtight containers at 60–62% RH, burping as needed for 3–5 weeks to polish flavor.
Phenotype Notes and Selection: Seek phenos that balance vigorous stretch with strong lateral branching and early trichome onset (week 4–5). Aroma selection typically favors bright lemon and cedar with a crisp pine echo; these phenos often test higher in terpinolene/limonene/pinene. Watch for excessive foxtailing under high heat or light; moderate temps and PPFD can rein it in.
Expected Yields and Benchmarks: Under 600–900 µmol/m²/s LED and competent environmental control, 600–750 g/m² is a realistic indoor target with a 9–10 week bloom. CO₂-enriched rooms and dialed ScrOGs can surpass 800 g/m² with elite clones. Outdoors in favorable latitudes, plants exceeding 2 meters tall and 1–1.5 kg per plant are achievable with full-season sun and sturdy soil biology.
Outdoor Considerations: Plant after last frost and aim for full-day sun; a Mediterranean climate yields the best results. Finish time is typically mid to late October, so select locations with low autumn rain if possible. Prevent mold in late season with leaf thinning, wide plant spacing, and proactive site airflow.
Autoflower Variant Strategy: Autos labeled “Moby Dick” commonly finish in 70–85 days from sprout with a compact-to-medium stature. Light schedules of 18–20 hours work well, and THC is often cataloged at 15–20%. Autos prefer minimal stress; use gentle LST instead of topping, and pot up early to 11–15 L containers for a full cycle.
SOG vs. ScrOG: Sea of Green is feasible with small plants flipped early (10–14 days veg), capitalizing on single cola formation and rapid turnover. ScrOG is arguably the sweet spot for photoperiods, allowing tall genetics to be tamed into a productive, even canopy. Choose based on ceiling height, plant count limits, and workflow preference.
Flushing and Harvest Timing: For soil grows with heavier feeding, a 7–14 day flush can remove residual salts; coco/hydro growers often reduce EC gradually in the final 7–10 days. Harvest when milky trichomes predominate with 5–15% amber for a balanced effect profile. Target water activity of 0.55–0.65 during cure to lock in long-term quality.
Quality Control and Common Pitfalls: Overstretch without training can cause larfy lowers and inconsistent ripening. Inadequate airflow around big colas elevates botrytis risk—prioritize spacing and de-leafing. Overdrying during post-harvest can mute the citrus top notes; keep your dry room in range and avoid high-heat trimming.
Market Position and Commercial Notes: Moby Dick frequently appears in “high yield” and “dense bud” seed categories, reflecting its commercial viability. Autoflower catalogues often label it “high THC” at 15–20%, allowing rapid production runs with respectable potency. Its recognizable name and lemon-cedar signature make it a reliable menu anchor for producers targeting sativa-leaning consumers.
