GH Amnesia VS Exodus Cheese

Executive Summary: GH Amnesia vs Exodus Cheese at a Glance

This guide delivers a data-forward comparison of GH Amnesia (Green House Seeds’ Amnesia) and the Exodus Cheese (UK Cheese) cut, focusing on genetics, cultivation, chemistry, and end-user effects. The target topic is GH Amnesia VS Exodus Cheese, and the analysis centers on cultivation realities and measurable outcomes.

GH Amnesia skews sativa with classic Haze traits, longer flower times, higher stretch, and elevated THC potential. Exodus Cheese is a stout, skunk-derived powerhouse with shorter cycles, denser buds, and one of the strongest odor signatures in cannabis.

If you want aggressive vigor, big canopies, and citrus-haze terpinolene complexity, GH Amnesia is the higher-ceiling option. If you need reliable turnarounds, pungent bag appeal, and easier canopy control, Exodus Cheese is the pragmatic workhorse.

Across controlled indoor runs, GH Amnesia regularly reaches 600–700 g/m² in 63–70 days of flower with THC often 18–25%. Exodus Cheese typically produces 500–600 g/m² in 56–63 days with THC around 16–20% and exceptionally strong aroma-driven demand.

Both strains carry low CBD (<0.5%), but differ sharply in terpenes: GH Amnesia trends terpinolene-leading, while Exodus Cheese leans caryophyllene–myrcene–humulene. These chemical differences drive contrasting effects—stimulating and heady for Amnesia, balanced and relaxing for Cheese.

Origins, Lineage, and Breeder Background

GH Amnesia refers to Green House Seeds’ take on the iconic Dutch Amnesia lineage. Amnesia traces back to Haze-influenced genetics from the Netherlands, often linked to a select-grown Hy-Pro lineage and refined by Dutch breeders through the 1990s and 2000s.

Green House Seeds standardized this profile for seed growers, seeking a stable sativa-dominant phenotype with a manageable flower time. The goal was to keep the hazy, uplifting effect and citrus-herbal profile while reducing the classic 12–14-week haze cycle.

Exodus Cheese is the famous UK Cheese clone, discovered in the United Kingdom in the early 1990s from a Skunk #1 population. The “Exodus” moniker comes from the Exodus collective, a group central to the UK underground scene that safeguarded and distributed the cut.

Unlike GH Amnesia, Exodus Cheese is historically clone-only, which is why seed versions are “Cheese” derivatives rather than the exact cut. Many seed companies, including Green House, Big Buddha, and others, created seed lines to capture the cut’s distinct profile.

The genetic contrast is stark: GH Amnesia leans sativa with Haze architecture and terpinolene dominance, while Exodus Cheese is a skunk-forward, hybrid-leaning cultivar famous for its funk and density. This difference is visible from seedling vigor through post-harvest aroma.

Commercial growers often pair them in menus to offer a cerebral daytime option (GH Amnesia) and a comfort-heavy evening or social strain (Exodus Cheese). Their complementary effects and aromatic divergence increase consumer coverage without redundant offerings.

Chemotype and Terpene Profiles: Side-by-Side Data

THC for GH Amnesia commonly averages 18–25% in third-party tests, with top phenotypes occasionally cresting 26% under optimized lighting and CO₂. CBD typically remains low at 0.05–0.4%, with CBG measurable in the 0.2–0.8% range.

Total terpene content in well-grown GH Amnesia frequently falls between 1.2–2.5%, with terpinolene often the dominant terpene. Secondary terpenes include myrcene, ocimene, and beta-caryophyllene, with limonene present in citrus-leaning phenotypes.

Exodus Cheese generally tests 16–20% THC, with standout cuts at 21–22% in high-end dialing. CBD is typically negligible (<0.3%), while CBG often appears between 0.2–0.6%.

Terpene totals for Exodus Cheese often land in the 1.5–3.0% range when flowered under strong PPFD with proper drying and cure. Dominant terpenes trend beta-caryophyllene (0.3–0.6%), myrcene (0.2–0.5%), and humulene (0.1–0.3%), with supporting notes from linalool and pinene.

Aroma translates cleanly from the lab: GH Amnesia’s terpinolene drive produces citrus peel, sweet herb, and incense-pine. Exodus Cheese delivers sweet-and-sour skunk, cheddar funk, and earthy musk, with isovalerate-like notes that intensify during late cure.

User-reported effects match the chemistry. Terpinolene-led cultivars correlate with energizing, creative, and sometimes racy effects, while caryophyllene–myrcene–humulene chemotypes trend toward body comfort, mood elevation, and stress relief without heavy couchlock at moderate doses.

Morphology, Canopy Behavior, and Training Strategy

GH Amnesia exhibits sativa-leaning morphology with elongated internodes, narrow leaflets, and pronounced apical dominance. Expect 1.8–2.5x stretch after flip in most rooms, requiring proactive training.

Exodus Cheese grows more compact with tighter internodal spacing and broader leaflets. Stretch is typically 1.2–1.6x, making canopy control easier in short tents and single-layer SCROG nets.

For GH Amnesia, topping once or twice in late veg combined with low-stress training (LST) builds multiple mains to offset stretch. A trellis or SCROG is recommended, filling 60–70% of the net pre-flip to end up at 90–100% coverage by week 3–4 of flower.

With Exodus Cheese, single topping followed by light LST is often enough for an even canopy. Many growers prefer SOG with 9–16 plants per square meter, flipping at 20–30 cm to maximize uniform colas and minimize lower larf.

GH Amnesia’s calyx-to-leaf ratio is favorable on mature colas, but foliage density can spike during stretch. Strategic defoliation at day 21 and day 42 of flower, removing only obstructive fan leaves, improves airflow without triggering stress.

Exodus Cheese stacks dense, broad colas that can trap humidity, raising botrytis risk in late bloom. Thinning interior leaves and maintaining strong lateral airflow reduce microclimates, especially in rooms running higher plant counts.

Environmental, Feeding, and Irrigation Parameters

GH Amnesia tolerates slightly higher heat and light when supported by CO₂. Ideal day temps are 26–28°C (78–82°F) with CO₂ at 900–1200 ppm, dropping to 24–26°C (75–79°F) without enrichment.

Exodus Cheese prefers the cooler side for best terp retention and density. Aim for 24–26°C (75–79°F) daytime and 20–22°C (68–72°F) nights in late flower to avoid terpene volatilization and foxtailing.

Target VPD for both strains: veg at 0.8–1.2 kPa, early flower at 1.0–1.3 kPa, and late flower at 1.3–1.5 kPa. Maintain RH at 60–70% in veg, 50–55% weeks 1–4 flower, then 45–50% in late bloom.

For light intensity, GH Amnesia handles 900–1100 μmol/m²/s in flower with CO₂, achieving a DLI of 35–45 mol/m²/day. Exodus Cheese thrives at 700–900 μmol/m²/s, with some cuts peaking near 1000 μmol/m²/s if temps and feed are dialed.

Nutrient strength in coco/hydro for GH Amnesia often lands at EC 1.6–2.1 through mid-late flower. Maintain N at 90–110 mg/L in early bloom, P at 60–80 mg/L, K at 200–240 mg/L, Ca at 120–150 mg/L, Mg at 40–60 mg/L, and S at 60–80 mg/L.

Exodus Cheese tends to prefer EC 1.5–1.9 across bloom, with similar macro targets but slightly less total N after stretch. In coco, keep pH at 5.8–6.0; in hydro 5.7–5.9; in soil 6.3–6.8 for both strains.

Irrigation frequency depends on media. In coco, feed to 10–20% runoff 2–4 times daily under high PPFD and warm temps; in soil, irrigate every 2–3 days to 10% runoff after pots dry back to 50–60% of field capacity.

Add 2–4 ml/gal of a balanced cal-mag in RO water systems, especially for GH Amnesia during the rapid stretch phase. Monitor runoff EC and pH weekly; a 0.2–0.4 EC rise in runoff signals salt accumulation and the need for a corrective flush.

Flowering Time, Yield, and Quality Metrics

Indoors, GH Amnesia typically finishes in 63–70 days depending on phenotype and environment. Pushing to day 70–73 often increases oil content and terpinolene expression but should be balanced against production schedules.

Exodus Cheese commonly finishes in 56–63 days, with many growers harvesting at day 60–61 for optimum density and flavor. Taking Cheese beyond day 63 can dull some of the brighter top notes and risk botrytis in tight colas.

Yield for GH Amnesia under high-efficiency LEDs (e.g., 2.5–3.0 μmol/J fixtures) frequently falls between 600–700 g/m². Growers running CO₂ and dialed canopy management report pushing 750 g/m² on large, uniform SCROGs.

Exodus Cheese produces consistent 500–600 g/m² yields with less canopy overhead. SOG layouts with 16 plants/m² can reach the upper end of that range by optimizing cola count and minimizing veg time.

Bud structure differs: GH Amnesia forms elongated, spear-like colas with medium density and extensive resin coverage. Exodus Cheese packs golf- to soda-can-shaped colas with high calyx density and thick trichome coverage that boosts bag appeal.

Quantitatively, trichome head distributions tend to cluster around 90–120 μm for both strains, but Cheese often presents a slightly higher ratio of mature, intact heads at harvest. That translates to strong performance in bubble hash and solventless yields, with Cheese often at 18–22% rosin return and GH Amnesia at 15–20% depending on phenotype.

Indoor Playbooks: SCROG vs SOG, CO₂, and IPM

For GH Amnesia, a SCROG approach shines due to the 1.8–2.5x stretch and branch flexibility. Fill the net 60–70% pre-flip, tuck daily through week 2–3, and stop manipulation by day 21 to avoid stress.

Exodus Cheese excels in SOG with 9–16 plants/m². Flip early at 20–30 cm, remove lower growth by day 21, and maintain a single apical cola per plant to reduce pruning labor and larf.

CO₂ enrichment at 900–1200 ppm can boost biomass by 15–30% when PPFD exceeds 800 μmol/m²/s and temperatures are elevated accordingly. GH Amnesia leverages this best, often translating directly to yield and terpene totals.

Odor control is non-negotiable with Exodus Cheese. Use oversized carbon filters with at least 700–1000 g of high-grade activated carbon per 6-inch filter and maintain negative pressure; double-filtering intake and exhaust reduces breakthrough.

Integrated Pest Management should be preventative. For both cultivars, weekly applications of Bacillus subtilis or B. amyloliquefaciens during veg reduce powdery mildew pressure, while predatory mites like Amblyseius swirskii and A. cucumeris suppress thrips.

Spider mites favor warm, dry leaves and can ravage GH Amnesia’s large canopies; release Phytoseiulus persimilis at the first sign of Tetranychus. Rotate modes of action and avoid late-flower sprays; rely on environmental control and predators after week 3.

Outdoor and Greenhouse: Climate, Training, and Harvest Windows

GH Amnesia is better suited to warm, dry climates or greenhouses with dehumidification. Outdoor harvest in the Northern Hemisphere typically lands late October, sometimes early November, which can be risky in wet regions.

Exodus Cheese finishes earlier outdoors, often in early to mid-October. That window reduces exposure to autumn rains and lowers botrytis risk in temperate zones.

In full sun, GH Amnesia can exceed 700–1000 g per plant with ample root volume and staking. Use sturdy tomato cages or multi-point trellising to support long, spear-shaped colas against wind.

Exodus Cheese can also push 600–900 g per plant outdoors with early topping and a low, wide frame. Thinning interior branches around late August helps airflow when nights cool and dew point rises.

Greenhouse growers should target aggressive airflow—pad-and-fan systems producing 30–60 air exchanges per hour during peak heat. Deploy horizontal airflow fans and maintain a 5–8°C day-night differential to balance internode length and terpene retention.

Guttation and prolonged leaf wetness increase fungal incidence. Run irrigation at dawn or early morning so canopies dry by midday; avoid evening watering and maintain RH below 60% in the last 3–4 weeks of flower for both strains.

Aroma, Flavor, Effects, and Use-Cases

GH Amnesia presents a citrus-zest front end with sweet herbal tea, pine incense, and occasional floral spice. Vaporization at 180–190°C emphasizes terpinolene brightness and limonene snap, while combustion brings out deeper incense notes.

Exodus Cheese offers unmistakable sweet-sour skunk, cheddar funk, and earthy musk with savory undertones. Lower temperature vaping (175–185°C) highlights caryophyllene bite and myrcene earth, while higher temps intensify the cheesy tang.

Effects diverge meaningfully. GH Amnesia is energizing, creative, and often euphoric, with a faster mental cadence that some users describe as racey at higher doses.

Exodus Cheese leans toward balanced mood elevation and body ease. It can be social and giggly in moderate doses, moving into calm, content relaxation without heavy sedation for many users.

In survey-style user feedback, daytime productivity and creative tasks trend toward GH Amnesia, while evening unwinding, appetite support, and stress relief trend toward Exodus Cheese. Sensitive users prone to anxiety often fare better with Cheese’s caryophyllene-rich profile.

For beginners, start low: 1–3 inhalations for GH Amnesia to gauge mental lift, and 2–4 for Exodus Cheese depending on tolerance. For experienced users, 0.1–0.2 g session weights offer clear differences in pacing and functional outcomes.

Medical and Functional Considerations

GH Amnesia’s terpinolene-forward profile often aligns with mood elevation, fatigue mitigation, and attention support in non-clinical reports. Some patients find it helpful for daytime depression symptoms and ADHD-adjacent focus challenges, though overstimulation can occur at higher doses.

Exodus Cheese’s caryophyllene–myrcene–humulene triad aligns with stress relief, appetite stimulation, and musculoskeletal comfort. Beta-caryophyllene’s activity at CB2 receptors is frequently cited for its potential in inflammatory modulation.

Pain phenotypes that respond to anti-inflammatory pathways sometimes prefer Exodus Cheese. Gastrointestinal symptom management also trends better with Cheese due to appetite and nausea mitigation.

GH Amnesia can exacerbate anxiety or palpitations in sensitive individuals at high intake. Dosing on a full stomach and pairing with calming activities can reduce intensity.

As both strains are low in CBD, patients seeking anxiolysis without psychoactivity may prefer adding a 10–20 mg CBD companion dose. Balanced THC:CBD formulations often widen the therapeutic window and reduce adverse events.

Always consult local regulations and medical professionals where medical cannabis is regulated. Individual responses vary, and titration remains the cornerstone of safe, effective use.

Drying, Curing, and Extraction: Protecting Volatiles and Maximizing Returns

Dry both cultivars in 18–20°C (64–68°F) at 55–60% RH with gentle airflow and darkness for 10–14 days. This slow dry preserves monoterpenes like terpinolene and limonene that flash off quickly above 22°C.

Aim for stem snaps that are audible but not brittle before trimming. Target a jar cure at 60–62% RH, burping daily for the first 10 days, then weekly for another 2–3 weeks.

Water activity between 0.55–0.65 aW stabilizes microbial risk and terpene volatility. Use small digital hygrometers in curing containers to maintain consistency.

For rosin, Exodus Cheese often returns 18–22% from flower pressed at 82–88°C (180–190°F) with a 60–90 second press and moderate pressure. GH Amnesia commonly yields 15–20% under similar parameters, with more variance based on phenotype.

For hydrocarbon extraction, both strains yield strong returns, but GH Amnesia’s terpinolene can be delicate during post-processing. Lower purge temps and longer vacuum times protect bright top notes.

Hash makers seeking full melt are more likely to favor Exodus Cheese due to
