MOB is shorthand for Mother of All Berries, a proudly East Coast cultivar also circulated as Maine Original Blueberry. Growers and consumers recognize it as a mostly indica phenotype with a reputation for fast finishes, chunky flowers, and deep berry aromatics. The breeder of record is unknown or legendary, a nod to the strain’s underground Maine origins and the tight-knit legacy scene that preserved it. In many markets it is simply labeled “MOB,” but dispensaries and seed vendors often include the full moniker or the Maine reference to avoid confusion.
This variety is often grouped with classic Blue family lines due to its unmistakable blueberry jam profile and its squat, indica-forward growth habit. It rose to prominence in the late 2000s and early 2010s in New England, where short seasons reward fast-maturing genetics like MOB. Consumers prize it for a sedative, appetite-stimulating experience that aligns with what Leafly lists as sleepy, relaxed, and hungry effects. The strain also carries a caution for dry mouth, dry eyes, and occasional anxiety in sensitive users, which is consistent with user reports on indica-dominant cultivars of similar potency.
Under the hood, MOB’s chemistry often shows limonene as the lead terpene with supporting roles from myrcene and beta-caryophyllene. That terpene balance helps explain its paradoxical bright-citrus top note alongside heavy berry and calming body effects. Typical THC values appear in the mid-to-high teens into the low 20s, with CBD remaining minimal. For patients and connoisseurs alike, MOB exemplifies a berry-forward nighttime flower that excels in short-season cultivation and in end-of-day routines.
History and Regional Roots
Most accounts place MOB’s rise in Maine, where small-batch cultivators refined a blueberry-leaning indica cut that finished reliably before coastal autumn rains. The region’s outdoor window, which often tightens by late September, favors cultivars that can flower fully in 7–8 weeks. MOB’s dependable finish and mold resistance made it a reliable performer in this environment. Word-of-mouth dissemination spread it through New England before it appeared on broader dispensary menus.
While no single breeder has claimed definitive authorship, a consensus formed around its legacy status and Maine provenance. This explains the alternate epithet Maine Original Blueberry, capturing both terroir and flavor lineage. As regulated markets expanded in the Northeast, MOB kept its reputation for consistent effects and manageable cultivation. It also benefited from a nostalgia wave that revived berry-leaning indicas in rotation alongside dessert-inspired hybrids.
The strain’s staying power reflects practical strengths more than hype cycles. Growers valued MOB for its stout structure and predictable nutrient appetite, while consumers embraced its evening-friendly relaxation profile. In markets like Massachusetts and Maine from 2018–2024, MOB periodically appeared on menus with lab-verified THC in the mid-teens to low 20s, a range that met consumer expectations without overwhelming new patients. Its regional loyalty remains strong, but the cut circulates widely enough that it’s now a recognized name well beyond New England.
Importantly, MOB’s identity sometimes gets muddled with Mob Boss, a separate cultivar with sativa-leaning traits that has appeared in New York coverage and seed catalogs. MOB is indica-forward and blueberry-heavy, whereas Mob Boss is known for an energetic, cerebral push. Retailers often spell out “Mother of All Berries” to maintain clarity. If a product claims uplifting, speedy effects, it likely references Mob Boss rather than MOB.
Genetic Lineage and Breeding Hypotheses
The precise lineage of MOB is undocumented, but sensory and growth cues suggest heavy influence from the Blueberry family combined with an Afghan indica backbone. The compact stature, thick calyxes, and purple-leaning phenotypes resonate with Blueberry and Afghani ancestry. The berry-jam terpene stack with limonene up top and myrcene underneath fits well with such a hypothesis. The brevity of its flowering window further points to indica-dominant genetics selected for northern latitudes.
Legacy growers from Maine frequently describe selections that emphasized early finishing and mold tolerance due to humid coastal weather. Those priorities typically steer breeders toward Afghan or Mazar-type parents, known for tight internodes and quick finishes. If a Blueberry mother was used, the result would readily produce the fruit-forward aromatic signature MOB is famous for. Limonene dominance could stem from the specific cut chosen rather than the entire population, explaining subtle variance between growers.
In the absence of a published pedigree, practical identification relies on consistent agronomic and sensory markers. The plant tends to show broad, leathery leaves, a dense lateral canopy, and terminal colas that stack with minimal spacing. Aromatically it blends blueberry preserves, candied citrus peel, and a faint pine-earth backbone. The effect profile, reported as sleepy, relaxed, and hungry, corroborates a myrcene- and caryophyllene-supported indica experience.
Given this, a plausible shorthand is Blueberry x Afghan (unknown selections), although it remains speculative. Some growers report phenotypes with more citrus-pop and less musk, hinting at minor outcross influences or environmental shaping of terpene expression. Until a verified genetic analysis is published, MOB should be treated as a stabilized, regional indica selection with Blue notes rather than a fixed, seed-company lineage. Its reliability in the garden and in the jar has done more to define it than any breeder’s lineage chart.
Botanical Appearance and Structure
MOB grows squat and sturdy, typically reaching 60–100 cm indoors without aggressive stretch after flip. Internodal spacing is tight, creating thick, contiguous colas that benefit from thinning leaves to enhance airflow. Leaves are broad and dark green, sometimes expressing anthocyanin purples in late flower as night temperatures dip. Buds are dense and conical with pronounced calyx swelling, making for chunky, weighty tops at harvest.
Trichome coverage is heavy and early, with resin glands appearing by the end of week 3 of bloom under optimized lighting. Pistils cluster densely and often shift from vibrant white to amber-orange as maturity approaches. In cooler rooms, bracts can mottled-purple, amplifying the blueberry aesthetic. The finished flowers cure to a sticky, resinous feel that breaks down slowly and releases waves of fruit aroma.
Branching is symmetrical and manageable, well suited to topping and low-stress training to widen the canopy. Because MOB packs weight close to the stem, stakes or trellis are recommended during weeks 6–8 of bloom to prevent leaning. Expect minimal foxtailing if temperatures are kept within ideal ranges, as the genetics tend toward compact flowers. Overall, the cultivar’s morphology is tailor-made for small tents and commercial rooms alike.
Outdoor plants remain relatively compact, typically 1.2–1.8 meters when transplanted early with full sun. The cultivar’s natural hardiness lets it handle cool nights common to northern latitudes, provided humidity is controlled. Its dense buds demand regular canopy maintenance outdoors to discourage botrytis. Gardeners often select MOB for the peace of mind that comes with a fast finish and a short, stout frame.
Aroma
The first aromatic impression is ripe blueberry preserves layered over a crisp citrus rind snap. That top-note sparkle aligns with limonene dominance documented by user-facing resources, giving MOB an aromatic uplift that belies its sedative effects. Beneath the fruit lies a gentle forest-floor earthiness and faint pine, hints commonly associated with myrcene and alpha-pinene. As flowers cure, the jammy sweetness intensifies while the citrus sharpness softens into candied peel.
Grinding a dried flower liberates a bouquet that shifts from simple berry to complex berry-citrus compote. Whiffs of warm spice and black pepper occasionally surface, consistent with beta-caryophyllene in the mix. Some phenotypes lean more tart and cranberry-like, especially when grown cooler, while warmer rooms can push a sweeter blueberry muffin scent. Regardless of environment, MOB announces itself as unmistakably berry-forward and clean.
Aroma intensity is notably high, especially post-grind, and lingers in the air longer than lighter floral cultivars. Total terpene content in well-grown batches typically falls around 1.5–3.0% by weight, a range commonly seen in premium indoor flower. While variance exists between growers, MOB’s fruit core remains resilient under different nutrient regimens. This predictable aromatic identity is part of why shops find it easy to sell as a “what you smell is what you get” strain.
During late flower, the room nose shifts from green-fruit to jammy and slightly gassy as trichomes mature. Careful control of drying conditions preserves that top-note brightness, as high heat or overdrying will strip the limonene pop. In jars, MOB maintains its bouquet for months if sealed well and kept under 60% RH. Many consumers report that a brief “burp” releases a wave of blueberry-citrus that fills the room instantly.
Flavor
On inhale, MOB delivers sweet blueberry syrup layered with lemon zest, immediately tying aroma to palate. The limonene lift adds a clean, sparkling citrus edge that keeps the flavor from feeling heavy. As the draw deepens, a soft herbal earth emerges, reflecting myrcene’s grounding influence. Exhale often leaves a sugary berry trail with a faint pepper tickle from caryophyllene.
Vaporization brings out nuanced cranberry and candied orange tones that may be masked in combustion. At lower temperatures around 170–185°C, the terpene balance leans fruit-forward and floral. Raising temperature toward 200°C introduces more herbal-spice and a light resinous pine finish. Consumers sensitive to harshness generally find MOB smooth, provided it’s properly flushed and cured.
Edibles made with MOB retain a surprising amount of berry character if the infusion is gentle. Butter or coconut oil extracts frequently exhibit a blueberry-marmalade note that pairs well with baked goods. Tinctures can taste zestier and less sweet, underscoring the limonene presence. Across formats, the through line remains bright berry with a balancing earth-spice.
Quality of cure significantly affects flavor persistence across the session. Well-cured flower maintains sweetness to the end of the bowl, whereas overdried flower collapses into a generic herbal taste. Most consumers describe MOB as a consistent, crowd-pleasing flavor that translates well from nose to tongue. That reliability makes it a staple recommendation for fruit-first palates seeking nighttime effects.
Cannabinoid Profile
MOB typically presents as a THC-dominant cultivar with minimal CBD. Dispensary COAs in New England markets commonly list total THC in the 16–22% range, with outliers approaching 24% in dialed-in indoor runs. CBD is usually trace, often <1%, and frequently undetectable in flower. Minor cannabinoids such as CBG and CBC appear in small amounts, roughly 0.1–0.6% combined in many tests.
The ratio of THC to CBD in MOB therefore favors a classic indica-style psychoactivity dominated by THC with little CBD buffering. Consumers should expect potency to feel pronounced despite mid-to-high teens numbers due to terpene synergy, often called the entourage effect. In practical terms, the strain can feel stronger than a comparable THC value in a low-terpene sample. This is especially true in batches with terpene totals above 2%.
Concentrates derived from MOB can concentrate THC well into the 60–80% range depending on extraction method. Live resins and rosin made from terpene-rich material typically capture limonene and myrcene in favorable proportions, preserving the strain’s signature. Edible makers often standardize to 5–10 mg THC per serving regardless of source flower potency, but MOB’s terpene-forward character can influence perceived onset. Users sometimes report a faster subjective onset compared with more neutral-tasting indica extracts.
For medical users who require CBD, MOB is not a primary source and is better paired with a CBD-dominant cultivar or product. Alternatively, balancing with a 1:1 tincture can soften the heavy THC edges while preserving flavor and appetite benefits. Patients new to THC should start low, especially given MOB’s sleepy and hunger-forward effects. A cautious titration helps avoid the occasional anxiety reported by sensitive users.
Terpene Profile and Functional Pharmacology
Across user reports and lab menus, limonene frequently tests as the dominant terpene in MOB, followed by myrcene and beta-caryophyllene. This aligns with the live-info reference noting limonene at the top of the list for Mother of All Berries. Total terpene content commonly lands between 1.5% and 3.0% in well-grown indoor flower. Minor contributors may include linalool, alpha-pinene, and humulene, rounding out the earthy-spice undertone.
Limonene is associated with citrus aromatics and can subjectively lift mood and reduce stress in some users. Myrcene, often linked to sedative, couchlock tendencies in indica lines, likely underpins MOB’s sleepy effect. Beta-caryophyllene binds to CB2 receptors and is studied for anti-inflammatory potential, which may complement MOB’s relaxing body effects. Linalool and humulene, when present, can layer calming and appetite-modulating nuances.
The combined limonene-myrcene-caryophyllene triad offers a helpful heuristic for predicting MOB’s experience. Limonene may brighten the initial headspace, preventing a purely heavy onset that some pure myrcene-dominant flowers deliver. Myrcene then deepens the relaxation, while caryophyllene smooths body discomfort and adds a pepper-spice edge to the flavor. This synergy explains why MOB can feel both cheerful and sedative, an appealing paradox for evening use.
From a cultivation standpoint, terpene expression in MOB responds to environmental parameters. Cooler night temperatures near the end of flower can enhance the berry esters and preserve limonene. Overly high drying temperatures will volatilize limonene rapidly, flattening the taste. For processors, low-temp extraction and careful purging safeguard the fruit-forward top notes central to MOB’s identity.
Experiential Effects and Onset Dynamics
Consumer reports and the Leafly profile converge on three primary effects for MOB: sleepy, relaxed, and hungry. The onset is moderately quick, with users often noticing a mood lift within 5–10 minutes of inhalation. As the session continues, muscles loosen and mental chatter diminishes, transitioning toward a drowsy calm. Appetite stimulation follows reliably, making late-night snacks a common side effect.
While the head effect is present, it rarely becomes racy when doses are modest. At higher doses or in sensitive individuals, anxiety can occur, which aligns with the live-info note listing anxious as a possible negative. Dry mouth and dry eyes are typical, and staying hydrated mitigates these discomforts. Many users set MOB aside specifically for evenings, pairing it with sleep hygiene routines.
Duration of noticeable effects typically ranges from 2–3 hours for inhalation, with a pronounced tail of sedation. In edible form, the sedative and appetite effects can carry longer, often 4–6 hours depending on dose and metabolism. Because limonene can impart a bright first impression, some users feel sociable at the start before the body heaviness takes over. Planning activities accordingly helps avoid drowsy surprises.
Functionally, MOB pairs well with calm activities such as movies, stretching, or journaling. It is less suited for tasks demanding precision or alertness. Novice consumers should start with 1–2 inhalations or a 2.5–5 mg edible dose and wait to assess. Experienced consumers may appreciate MOB’s reliable wind-down, especially after physically demanding days.
Potential Medical Applications
MOB’s sedative, relaxing, and appetite-boosting profile suggests utility for insomnia, stress, and appetite loss. Patients dealing with sleep initiation problems often report easier onset when dosing MOB 60–90 minutes before bed. The combination of muscle relaxation and reduced rumination can support a fuller sleep cycle for some individuals. As always, responses vary, and establishing a consistent routine improves outcomes.
Appetite stimulation is a hallmark, making MOB relevant for patients experiencing nausea or decreased appetite from treatments. For example, individuals undergoing chemotherapy or dealing with gastrointestinal disorders may find MOB’s hunger cues helpful. The citrus-berry flavor profile is generally well tolerated, which can matter for patients sensitive to pungent or fuel-heavy strains. Inhaled forms offer rapid relief, while low-dose edibles can provide sustained support.
The beta-caryophyllene content may complement analgesic strategies for inflammatory discomfort. Patients with chronic low back pain or arthritis sometimes report transient relief and improved ease of movement. Myrcene’s relaxing influence can further ease muscle tightness or spasms, aiding conditions like restless legs at night. However, MOB’s THC-forward nature means some users may feel foggy, so daytime medical use warrants caution.
Potential side effects include dry mouth, dry eyes, and occasional anxiety, as reflected in the live-info overview. Patients with a history of panic attacks should start at very low doses or consider a CBD supplement to buffer the experience. Those prone to orthostatic hypotension should rise slowly from seated positions due to relaxation-induced lightheadedness. Medical supervision, especially when combining cannabis with other sedatives, is advisable.
Comprehensive Cultivation Guide
MOB rewards both novices and advanced cultivators with a relatively forgiving growth curve and dependable yield. Indoors, a common flowering window is 49–56 days (7–8 weeks), with some phenotypes leaning closer to 60 days when maximizing density. Outdoor growers in northern latitudes often finish by late September to early October, dodging the heaviest fall rains. The cultivar’s mold tolerance is moderate to good when airflow and humidity are managed.
For indoor environments, aim for daytime canopy temperatures of 24–27°C during veg and 22–26°C in flower. Night drops of 3–5°C in late bloom can enhance color and preserve volatile top notes. Maintain relative humidity around 60–70% in early veg, 50–60% in late veg/early flower, and 45–50% by week 6 onward. A VPD in the 1.1–1.4 kPa range during mid-flower typically supports optimal gas exchange without over-drying.
Lighting intensity should reach 600–900 µmol·m⁻²·s⁻¹ PPFD across the canopy during bloom for soil or coco, and up to 1000–1200 under CO₂ enrichment. MOB’s short stature makes it ideal for uniform PPFD distribution in tents using bar-style LEDs. Topping once or twice in veg and integrating a single-layer trellis creates evenly spaced colas that minimize larf. Defoliation at weeks 3 and 6 of flower helps airflow through the dense canopy.
Nutrient-wise, MOB prefers a moderate feed. In coco, target an EC of 1.6–2.0 mS/cm in mid-flower with a pH of 5.8–6.0, stepping down to 1.2–1.4 during the final flush. In living soil, top-dress with balanced amendments and monitor for nitrogen excess, as the plant’s broad leaves can mask early signs of overfeeding. Calcium and magnesium support are important under LED lighting, so consider 100–150 ppm Ca and 50–80 ppm Mg in solution.
Plant training should prioritize lateral expansion rather than vertical height. Low-stress training, mainline or manifold techniques, and SCROG all work well to maximize the cultivar’s natural uniformity. Avoid excessive supercropping in late flower, as the dense colas can stress-split. Support heavy tops with stakes or a second trellis if colas exceed 30–40 cm in length.
Watering cadence benefits from a wet-dry cycle that does not fully desiccate the medium, preserving microbe health and terpene potential. In coco, multiple small irrigations per day via drip can keep EC stable and reduce salt stress. In soil, allow 10–20% runoff when watering to minimize buildup, adjusting frequency based on pot weight and plant transpiration. Good root zone oxygenation reduces risk of root pathogens, which can be a concern with dense foliage.
Pest and disease management should anticipate powdery mildew and botrytis in dense flowers. Preventative IPM with sulfur vapor in veg or potassium bicarbonate sprays early in flower can reduce mildew pressure. Ensure strong horizontal airflow and adequate dehumidification to keep leaf-surface moisture in check. Beneficial insects such as Amblyseius swirskii and Hypoaspis miles can form a biological baseline against thrips and fungus gnats.
Flowering, Yield, and Post-Harvest Handling
Expect indoor yields in the range of 400–550 g/m² under efficient LEDs, with experienced growers occasionally surpassing 600 g/m² via SCROG. Outdoors, yields of 500–1000 g per plant are common with adequate sun and nutrition, with larger plants exceeding 1.5 kg in optimal conditions. MOB consolidates weight into terminal colas, so light penetration and cola spacing drive outcomes. Harvest timing is often optimal when 10–20% of trichomes turn amber with the remainder cloudy.
As harvest nears, aromas shift from bright berry to jammy and slightly resinous. Flushing or tapering EC during the final 10–14 days can improve burn quality and preserve flavor. Trichome inspection under 60–100× magnification ensures precision and helps avoid premature harvests, which can mute the sleepy effect. When grown cool in late flower, anthocyanin expression enhances bag appeal without sacrificing terpene intensity.
Drying should be slow and controlled to retain limonene, a volatile terpene central to MOB’s profile. Target 60°F/15.5°C and 55–60% RH for 10–14 days with gentle air exchange. Avoid direct airflow on hanging branches to prevent terpene stripping and localized overdrying. Stems should snap rather than bend before trimming and jarring.
Curing extends flavor depth and smoothness. Burp jars daily for the first 7–10 days, then weekly for 3–4 weeks while maintaining 58–62% RH with humidity packs if needed. Properly cured MOB retains its blueberry-citrus core for months and grinds with a satisfying stickiness. Total terpene values tend to stabilize after a 3–4 week cure, delivering the signature jammy-sweet palate that consumers expect.
Strain Identity and Common Mix-Ups
Because the acronym “MOB” appears in multiple contexts, it is sometimes confused with Mob Boss, a different strain with sativa-leaning, energetic effects. Coverage of Mob Boss in New York and seed catalogs occasionally overlaps in search results, but the two cultivars diverge sharply in experience and aroma. MOB, Mother of All Berries, is indica-dominant, blueberry-forward, and sleepy-relaxing-hungry as reported on Leafly. Mob Boss trends brighter, more cerebral, and is often described as talkative or creative by reviewers.
To ensure you have the correct strain, confirm the full name Mother of All Berries or Maine Original Blueberry on labels. Look for berry-jam aromatics and a squat, fast-flowering structure in the garden. Lab reports for MOB usually feature limonene as a lead terpene with myrcene and caryophyllene behind it, while Mob Boss can test differently depending on cut. When in doubt, consult dispensary staff or growers who can describe the sensory cues and intended effects clearly.
Maintaining clear nomenclature safeguards patient outcomes, especially for those seeking sedative night-time relief. A sativa-forward mispurchase could complicate sleep routines and increase anxiety for sensitive individuals. Conversely, MOB’s heaviness might not suit daytime focus seekers who intended to buy Mob Boss. Taking a moment to verify the lineage and effect descriptors prevents these mismatches.
