Ghost Memory OG, sometimes listed on menus simply as “Ghost Memory” or “Ghost Memory OG Strain,” is a boutique hybrid prized by connoisseurs for its striking balance of cerebral lift and OG-style body weight. The name signals what most enthusiasts assume is the cross: Ghost OG paired with Memory Loss, an Archive Seed Bank cultivar. As with many clone-only or small-batch creations, availability, spelling, and phenotype expression can vary by region and grower.
In dispensary write-ups and grow forums, Ghost Memory OG is frequently described as potent but nuanced, delivering both sharp mental focus and classic kush calm. It is typically categorized as a hybrid that leans slightly sativa in headspace while keeping an indica-like physical relaxation in the background. That duality, combined with dense, heavily frosted flowers, has earned it a devoted following in West Coast markets.
Given its likely parentage, this cultivar tends to show terpene complexity beyond a standard OG, with bright top notes layered atop gassy depth. Consumers note that it performs consistently well in both combustion and vaporization, with flavor longevity that persists well into the final pulls. Because naming conventions can vary, shoppers should confirm genetics through posted certificates of analysis (COAs) when possible.
Origins and History
While the precise breeder of Ghost Memory OG has not been universally verified, the most commonly cited lineage matches Ghost OG with Memory Loss. Ghost OG is the famed OG Kush cut carried into prominence by the Ghost collective in the 2000s, celebrated for lemon-pine gas and a reliably heavy high. Memory Loss, developed by Archive Seed Bank, is widely reported as Amnesia Haze crossed with Face Off OG BX1, yielding intense terpinolene-forward aromatics and strong potency.
The likely pairing follows a classic breeding logic: blend the lucid, electric Haze influence with the grounding, euphoric body of a proven OG. This approach gained traction in the mid-to-late 2010s as consumers increasingly sought hybrids that could energize creativity without forsaking physical comfort. Ghost Memory OG appears to have emerged from this period of experimental recombination, circulating first as a clone among craft cultivators before trickling into broader production.
Because the cultivar did not launch with a large seed drop or a mass-market rollout, it remains relatively rare in some regions. The scarcity has nurtured a reputation as a “connoisseur’s pick,” further boosted by the strong visual bag appeal and reliable potency. When located in legal markets, COAs typically show mid-20% THC potential, aligning with the prevailing demand for high-test OG hybrids.
Genetic Lineage and Breeding Rationale
Most reports align on Ghost Memory OG as a fusion of Ghost OG (an OG Kush phenotype) and Memory Loss (Amnesia Haze × Face Off OG BX1). This makes it an OG/Haze hybrid with two different OG influences: one from Ghost OG and another embedded within Memory Loss via Face Off OG. The result tends to be a terpene-rich profile blending citrus-diesel OG funk with the herbal, floral, and sometimes spearmint-like top notes associated with terpinolene-heavy Haze lines.
From a breeding standpoint, the combination targets synergy across several axes: terpene complexity, vigor, and diversified effect. Ghost OG brings dense resin heads, kush structure, and euphoric body relief, while Memory Loss contributes a zesty lift and heightened sensory clarity. Breeders often pursue this blend to achieve a cultivar that can test high in total cannabinoids while offering an effect that remains functional at moderate doses.
Phenotypically, two archetypes appear. One leans OG with fatter calyxes, deeper gas, and broader leaves in early veg; the other leans Haze with a taller frame, narrower leaves, and a louder, more floral-citrus top end. Both types can be highly resinous, though the Haze-leaning phenotype may produce slightly longer internodes and benefit more from training and trellising.
Appearance and Bud Structure
Mature flowers generally present as dense, spear-shaped colas with a generous trichome blanket that can look almost sugar-coated under light. Coloration ranges from lime to forest green with copper-orange to rust pistils, and occasional lavender hues under cooler night temps. The calyx-to-leaf ratio is favorable, simplifying hand-trimming and improving jar appeal.
OG-dominant phenotypes often stack into tight, golf-ball to torpedo-shaped nugs with minimal fox-tailing when environmental parameters are controlled. Haze-leaning expressions can show light fox-tailing late in flower, especially under high light intensity or heat, but still finish with a respectable density. In either case, resin heads tend to be abundant, with bulbous capitate-stalked trichomes that hold up well through drying and curing if handled gently.
Under magnification, trichome heads typically appear well-formed and numerous, a visual indicator of the cultivar’s potency potential. Growers frequently report a sticky, tacky feel during harvest that complicates scissors but bodes well for rosin yields. In cured jars, the flowers retain a bright sheen and emit a layered aroma that often intensifies when broken up.
Aroma and Flavor
Ghost Memory OG’s aroma generally opens with bright citrus—lemon zest and sweet orange—wrapped in classic OG fuel and pine. Many cuts add an herbal, almost spearmint or eucalyptus lift attributed to terpinolene expression from the Memory Loss side. Beneath the top notes, peppery spice and earthy kush linger, hinting at beta-caryophyllene and humulene contributions.
On the palate, expect a crisp lemon-pine entrance followed by diesel zest and a flinty minerality common to strong OG lines. The exhale can pivot to herbal-spice with a touch of anise or fennel, finishing on a mouth-coating kush resin. Vaporization at 180–190°C accentuates the citrus-floral compartment, while 195–205°C unlocks deeper fuel, pepper, and wood.
Compared to a straight OG, Ghost Memory OG is usually brighter and more aromatic at room temperature, with terpenes volatilizing quickly when the jar is cracked. The bouquet amplifies noticeably when the bud is ground, releasing terpene-rich oils across a wide spectrum. This top-to-bottom complexity explains why the cultivar holds flavor deep into longer sessions.
Cannabinoid Profile and Potency
COAs reported publicly for OG/Haze hybrids analogous to Ghost Memory OG commonly land in the 20–26% THC range, with outliers from 18% on the low end to 28% on the high end. Ghost Memory OG itself is usually characterized as a high-THC cultivar, with a practical median around 23–25% THC when dialed in. CBD content is typically low, often below 0.5%, aligning with the parentage.
Minor cannabinoids can register meaningfully. CBG often appears between 0.3–1.0%, CBC between 0.1–0.3%, and trace THCV—particularly plausible due to the Amnesia Haze heritage—may show at 0.05–0.2% in some phenotypes. Total cannabinoids can surpass 25–30% in well-grown batches when summing THC with minors.
Potency perception tracks not just with THC but with terpene content, which can modulate onset and intensity. Batches showing total terpene content above 2.0% by weight often feel more robust to consumers despite similar THC. As always, individual sensitivity varies, and set, setting, and tolerance strongly influence the subjective potency curve.
Terpene Profile and Chemistry
Total terpene content for Ghost Memory OG commonly falls between 1.5% and 3.0% by dry weight, placing it among the more aromatic hybrids when properly cultivated and cured. Two terpene expression patterns appear in grower and lab notes: a terpinolene-forward chemotype and a limonene/myrcene-dominant OG-leaning chemotype. Both profiles typically retain appreciable beta-caryophyllene, supporting the cultivar’s peppery undertone.
In the terpinolene-forward expression, terpinolene may chart at 0.30–0.80%, limonene at 0.30–0.60%, and beta-caryophyllene at 0.20–0.40%. Supporting terpenes commonly include ocimene (0.10–0.30%), linalool (0.05–0.20%), and humulene (0.08–0.20%). This configuration often smells brighter, more floral-herbal, and can feel more stimulating at low-to-moderate doses.
In the OG-leaning expression, limonene can lead at 0.40–0.70%, beta-myrcene at 0.30–0.60%, and beta-caryophyllene at 0.25–0.50%, with terpinolene reduced or present only in trace. Pinene is frequently notable (0.10–0.25%), contributing to the pine note and possibly aiding perceived alertness. The interplay of limonene and caryophyllene correlates with the lemon-pepper-fuel profile that OG enthusiasts prize.
From a chemovar standpoint, Ghost Memory OG exemplifies the utility of terpene layering to shape effect. Limonene and terpinolene both convey brightness, but terpinolene can tilt the headspace toward a racier, creative energy, while myrcene and caryophyllene provide grounding. This push-pull chemistry helps explain the cultivar’s versatility across daytime and evening contexts.
Experiential Effects and Use Cases
Most users describe a fast onset within 2–5 minutes when inhaled, peaking around 30–60 minutes and tapering over 2–3 hours. The opening notes are cerebral: uplifted mood, sensory crispness, and a noticeable clearing of mental fog. Physical effects build gradually, offering a warm heaviness in the shoulders and limbs without immediate couchlock at moderate doses.
At lower doses, Ghost Memory OG can feel purposeful and focusing, suitable for creative tasks, music, or light socializing. At higher doses, the OG body settles in, deepening relaxation and occasionally tipping into sedation, particularly in the last hour of the arc. Some users report increased introspection—pleasant for unwind sessions but potentially overwhelming for those prone to racing thoughts.
Compared to heavier OGs, the cultivar’s Haze influence can keep the headspace buoyant, especially in terpinolene-forward phenotypes. However, sensitive individuals may experience transient anxiety or a quickened heart rate if they overconsume, a known issue with high-THC, bright-terpene profiles. Beginners should start low, spacing puffs 10–15 minutes apart to gauge their response.
Practical use cases include daytime brainstorming, outdoor walks, and evening wind-down that avoids full sedation. Many note enhanced flavor appreciation during meals and an increased interest in music due to the cultivar’s sensory lift. Vaporization preserves clarity for some, while combustion can intensify the OG body—helpful for late-day relaxation.
Potential Medical Applications
While not a substitute for medical advice, the pharmacology suggested by Ghost Memory OG’s cannabinoids and terpenes points to several potential applications. THC at 20%+ is associated with analgesic and antiemetic effects, which can help with pain and nausea management for some patients. Beta-caryophyllene, a CB2 receptor agonist, may add an anti-inflammatory complement, potentially useful in conditions characterized by peripheral inflammation.
Patients with stress-related symptoms often report improved mood and reduced rumination with limonene-forward chemovars. The terpinolene component can enhance alertness and creativity, which some individuals find beneficial for fatigue and low motivation. However, those with anxiety disorders should approach cautiously; terpinolene-heavy expressions can be activating and may exacerbate anxiety at higher doses.
In appetite-related concerns, THC’s orexigenic effect is well-documented and may support patients experiencing reduced appetite. For sleep, the cultivar may assist in sleep onset at higher evening doses due to the OG body and myrcene contribution, though it is not as sedating as heavier indica-dominant kushes. Because CBD content is typically minimal, patients seeking anxiolysis without intoxication may wish to pair Ghost Memory OG with a CBD-rich cultivar or preparation.
Symptom categories where patients commonly report benefits include musculoskeletal pain, stress, situational anxiety, mild depression, migraine, and appetite support. Duration of relief tends to align with the inhalation kinetics: 2–3 hours for smoked or vaporized forms, potentially longer with oral formulations. Always consult a clinician familiar with cannabinoid therapy to tailor dose, route, and timing.
Cultivation Guide: Environment, Training, and Nutrition
Ghost Memory OG is a photoperiod cultivar that responds well to structured training, especially in small spaces. Expect a medium-to-tall plant with a 1.5–2.2× stretch after the flip, depending on phenotype and environment. Flowering time typically runs 63–70 days (9–10 weeks), with OG-leaning phenos finishing a bit earlier and Haze-leaning phenos needing the full window.
Environmentally, aim for day temperatures of 24–28°C and night temperatures of 18–22°C. Relative humidity targets of 60–70% in veg, 50–55% in early flower, and 40–45% in late flower help balance vigor and mold risk. Maintain VPD around 0.8–1.2 kPa in veg and 1.2–1.5 kPa in bloom to optimize gas exchange and transpiration.
For lighting, 400–600 PPFD in late veg builds a sturdy frame, while 900–1,100 PPFD in mid-to-late bloom drives high-density buds. If supplementing CO2, 1,000–1,200 ppm during lights-on can support PPFD up to ~1,200 without photo-stress, provided nutrition and irrigation are tuned. Without added CO2, keep peak PPFD closer to 900–1,000 to avoid diminishing returns.
Ghost Memory OG’s structure benefits from topping at the fifth to seventh node, followed by low-stress training (LST) and a single-layer SCROG or dual trellis. This spreads the canopy, increases lateral sites, and reduces the risk of top-heavy colas bending or breaking late in bloom. Strategic defoliation at day 21 and day 42 of flower (or similar) improves airflow and light penetration while minimizing shock.
Nutritionally, OG lines appreciate consistent calcium and magnesium. In coco or hydro, target EC of 1.2–1.6 in vegetative growth and 1.8–2.2 in bloom, keeping runoff pH around 5.8–6.2. In living soil or amended media, lean into balanced organic inputs with supplemental top-dressing of Ca/Mg and sulfur near transition to bolster terpene synthesis.
A practical NPK curve includes higher nitrogen in veg (e.g., 3-1-2 ratio equivalents), a balanced transition feed (e.g., 2-2-2), and a bloom tilt emphasizing phosphorus and potassium (e.g., 1-3-2 to 1-2-3) from week 3 onward. Monitor leaf petiole color and leaf margins; OG-leaning phenos can display K hunger late in flower if underfed. Keep an eye on EC drift and adjust irrigation frequency to maintain stable root-zone conditions.
Irrigation strategy depends on medium. In coco, multiple small fertigations per day at 10–20% runoff stabilize EC and promote fine root development. In soil, allow a gentle dryback between waterings and consider enzyme or microbial teas to maintain rhizosphere vitality, especially if pushing a 10-week finish.
Common pressures include powdery mildew (PM) and botrytis due to dense colas, especially under high humidity. Preventatively employ a strong IPM: environmental control, canopy spacing, rotating biologicals (e.g., Bacillus-based foliar in early veg), and beneficial insects for pests like fungus gnats or spider mites. Avoid late flower sprays; prevention and airflow are your best tools past week three.
Cultivation: From Germination to Harvest Timeline
Weeks 0–2 (Germination/Seedling): Maintain 24–26°C with 70–80% RH and gentle light (200–300 PPFD). Transplant once roots circle starter plugs, aiming for a moist-but-aerated medium. Begin light feeding at 0.6–0.8 EC if soilless; living soil seedlings can run on water alone until the first true leaves fully expand.
Weeks 3–5 (Early Veg): Increase PPFD to 300–450, RH to 65–70%, and establish early training. Top at node 5–7 and anchor branches with LST ties to set the scaffold. Feed at 1.0–1.3 EC in coco/hydro or maintain a steady soil moisture cadence with occasional microbial inoculants.
Weeks 5–7 (Late Veg/Pre-Flip): Push PPFD to 450–600 and begin trellising. Defoliate lightly to open interior nodes and transplant to final containers if not already done. Drop RH to 60–65% to prepare for flower and ensure robust airflow.
Weeks 1–3 Flower: Expect 1.5–2.2× stretch; manage with SCROG tucking and canopy leveling. Shift feed to 1.6–1.9 EC with increased P/K, and keep RH near 50–55%. A light defoliation around day 21 removes large fan leaves shading key sites.
Weeks 4–6 Flower: Bud set is pronounced; aromas intensify and resin heads multiply. Maintain 900–1,050 PPFD, 24–27°C day temps, and RH at 45–50%. Feed at 1.8–2.1 EC and watch for K and Mg demands; adjust supplements as needed.
Weeks 7–10 Flower: Density and oil production peak. Consider dropping night temps 2–3°C below day to enhance color and volatile retention, keeping RH 40–45%. Many OG-leaning phenos finish by day 63–67; Haze-leaners may prefer 67–70 days for full terp and cannabinoid maturity.
Harvest and Ripeness: Check trichomes with a jeweler’s loupe or microscope. For a balanced effect, harvest around cloudy with 5–15% amber; for more sedative tilt, 15–25% amber. Some terpinolene-forward phenos retain brighter aromatics if cut slightly earlier (e.g., 60–63 days), but confirm with trichome maturity.
Post-Harvest: Dry for 10–14 days at 18–20°C and 55–60% RH with gentle air exchange and minimal direct airflow on buds. Target a slow dry to avoid terpene loss; stems should snap rather than bend at the end of the dry. Cure in airtight containers burped daily for the first week, then 2–3 times per week for 3–4 more weeks; ideal water activity stabilizes near 0.55–0.62.
Yield Expectations and Grower Economics
Indoors, Ghost Memory OG typically yields 400–550 g/m² under high-intensity LED when the canopy is well-managed. Expert growers with CO2 enrichment and optimized PPFD can exceed 600 g/m², especially with a vigorous Haze-leaning phenotype. Outdoors, healthy plants in full sun with proper trellising often produce 500–800 g per plant, with exceptional results exceeding 1 kg in long-season climates.
The cultivar’s heavy resin and bag appeal can support premium pricing in quality-driven markets. However, labor inputs rise due to training, trellising, and careful environmental control to prevent PM and botrytis. Growers should budget for dehumidification capacity at 40–50% RH late in flower and plan for adequate airflow to safeguard quality.
From a processing standpoint, Ghost Memory OG is a strong candidate for hydrocarbon extraction and rosin, with resin returns commonly in the 18–25% range on select phenos. Terpene-forward profiles translate well into live resin and live rosin SKUs. Keeping harvest cold-chain-friendly preserves volatile terpenes and supports premium concentrate products.
Consumption Methods and Dosing Tips
Flower performs admirably in both joints and clean glass, with water filtration smoothing the OG body and preserving citrus brightness. For vaporization, 180–190°C showcases terpinolene and limonene, while 195–205°C unlocks deeper caryophyllene and myrcene for fuller body effects. Many users find 1–3 small inhales sufficient to reach a functional zone, with additional puffs reserved for evening depth.
Newer consumers should space doses by 10–15 minutes to avoid overshooting, given the cultivar’s high THC potential and stimulating top-end. Edible preparations derived from Ghost Memory OG can feel more sedative due to 11-hydroxy-THC metabolism; start with 2.5–5 mg THC and titrate slowly. Concentrate users should anticipate fast, forceful onset—single small dabs are typically adequate for experienced consumers.
Pairings that complement the profile include citrus-forward beverages, herbal teas, or piney gins for flavor synergy. For music and film, the cultivar’s sensory clarity often heightens detail and color perception. Avoid combining with excessive caffeine if you are sensitive to racy headspaces, particularly with terpinolene-leading cuts.
Common Pitfalls and Troubleshooting in Cultivation
Overfeeding late in flower can mute terpenes and produce harsh ash; watch for tip burn and EC creep in runoff. Conversely, underfeeding potassium from week 5 onward can limit density and reduce the characteristic OG resin sheen. Maintain a steady irrigation cadence—big swings in media moisture can increase susceptibility to root issues.
High humidity in dense canopies invites PM and botrytis; add oscillating fans, prune larf, and maintain a disciplined defoliation schedule. If PM pressure appears in veg, address immediately with environmental correction and early-stage biologicals; do not spray fungicides into late flower. Check for microclimates near walls and corners where air can stagnate.
Light stress can trigger fox-tailing in Haze-leaning phenos; back down PPFD by 5–10% or raise fixtures if you see exaggerated bract stacking. If aromatics seem muted, reassess drying conditions—too-fast dry at low RH strips volatiles. For terpene-forward results, target a 10–14 day dry at 18–20°C and 58–60% RH before a patient cure.
Comparisons to Similar Strains
Compared to Ghost OG, Ghost Memory OG is typically brighter and more complex aromatically, with less immediate sedation at moderate doses. Memory Loss presents a racier, more terpinolene-heavy profile that can feel sharp for some users, whereas Ghost Memory OG tempers that edge with OG body and euphoria. The net result is a middle path that many find suitable from mid-day into evening.
Against other OG/haze hybrids like Super Lemon OG or Amnesia OG, Ghost Memory OG often reads as slightly gassier and pepperier, with a thicker mouthfeel on the exhale. Limonene and caryophyllene synergy adds the signature lemon-pepper profile that OG enthusiasts recognize. The cultivar’s resin density and visual frost also compare favorably in the jar.
From a grower’s perspective, it stretches more than a pure kush but less than a classic Haze, anchoring it in a manageable training range. Flower time at 9–10 weeks is competitive for quality-forward hybrids, trading a bit more time for elevated terpene output. If you enjoy the uplifting clarity of terpinolene strains but want OG comfort, Ghost Memory OG occupies that niche adeptly.
Sourcing, Verification, and Quality Indicators
Because naming can vary by dispensary and region, verify genetics whenever possible through COAs or breeder notes. A high-quality batch of Ghost Memory OG will announce itself from the jar: layered citrus-gas, peppery undertones, and a persistent, clean finish. Visually, look for densely stacked calyxes with copious, intact trichome heads rather than a chalky or oxidized frost.
Lab metrics to scan include THC in the 20–26% zone and total terpene content above 1.5%, ideally exceeding 2.0% for connoisseur-grade aroma. Terpene breakdowns consistent with the profiles discussed—limonene, caryophyllene, myrcene or terpinolene, ocimene—support authenticity. Moisture content should be 10–12% or a water activity of ~0.55–0.62 to ensure both flavor and shelf stability.
For growers seeking cuts, source from reputable clone nurseries or trusted peers and consider quarantine and IPM intake protocols. Verify the plant’s growth cues in early veg—leaf shape, internodal spacing, and aroma on rub—as they often presage phenotype lean. Keep meticulous notes for phenotype selection, as differences in terpene balance can be decisive for market positioning.
Final Thoughts and Buyer’s Checklist
Ghost Memory OG stands out as a sophisticated hybrid marrying the bright, engaging lift of Haze influence with the satisfying weight and fuel of OG. Its typical potency, terpene richness, and resin density make it a favorite among experienced consumers and hashmakers alike. With careful drying and curing, the flavor arc remains compelling from first pull to last.
For patients and adult-use consumers, the cultivar’s versatility is a key draw: functional clarity at conservative doses, deep relaxation when pushed. For cultivators, success hinges on canopy control, environmental discipline, and a post-harvest process that protects volatiles. When these factors align, yields, COAs, and jar appeal can all exceed expectations.
Buyer’s checklist: seek THC in the mid-20s, total terpenes 2.0%+, citrus-gas-pepper aroma, dense frost, and a clean burn with light-gray ash. Grower’s checklist: 9–10 week finish, 1.5–2.2× stretch, late-flower RH at 40–45%, PPFD near 1,000, and robust Ca/Mg support. Whether you encounter it as “Ghost Memory OG” or “Ghost Memory,” confirm the profile—and enjoy one of the more balanced, modern expressions of OG-meets-Haze brewing in today’s market.
