UK Cheese

Also known as: Exodus Cheese, Cheese, British Cheese

Breeder: Clone Only — selected ~1988–89 by an anonymous UK grower from a pack of Sensi Seeds (The Seed Bank) Skunk #1; preserved and distributed by the Exodus Collective, Luton, England

UK Cheese is a legendary clone-only phenotype of Skunk #1 that emerged from a single seed pack grown in the Chiltern Hills of England around 1988–89. Its unmistakable sharp, savory, aged-cheese aroma was unlike anything else in cannabis at the time. The clone circulated underground among UK growers before reaching the Exodus Collective — a Luton-based activist community and free-party crew — around 1995. Exodus propagated and distributed the cut throughout the UK rave scene, making it the defining strain of British cannabis culture through the late 1990s and 2000s. One mother plant sustained a national network of growers thanks to heavy yields, a short flowering cycle, and an overwhelming smell that made secrecy nearly impossible. It remains one of the most influential cultivars in cannabis history, with SeedFinder.eu cataloguing over 420 direct descendants.

Lineage & Genetics

Cross: Skunk #1 (phenotype selection)

Skunk #1 — the foundational hybrid bred by Sam 'the Skunkman' (Sacred Seeds / Cultivator's Choice) in the late 1970s from Afghani × Colombian Gold × Acapulco Gold. Sam relocated to the Netherlands in the early 1980s and continued refining the line through Sensi Seeds / The Seed Bank. The specific pack that produced the Cheese phenotype came from this Dutch-era Skunk #1 stock.

Lineage Dispute

SeedFinder.eu and the Exodus crew maintain the original cut is a pure Skunk #1 phenotype selection with no hybridization. Some growers speculate it was crossed with an Afghani or Northern Lights, citing spicy undertones and dense indica-like bud structure atypical of Skunk #1. Big Buddha Seeds' seed version is a confirmed Cheese × Afghani ('The Kali') cross, but the original clone-only cut predates that work.

Terpene Profile

DOMINANT

MyrceneMusky, earthy foundation balancing citrus brightness

DOMINANT

CaryophylleneSpicy, peppery warmth with woody depth

SECONDARY

LimoneneBright citrus lift with lemon and orange zest

SECONDARY

HumuleneEarthy, hoppy bitterness with subtle spice

Aroma: Intensely pungent — sharp aged cheddar, sour skunk, damp earth, savory musk, with a faint sweet edge. Universally described as one of the loudest-smelling strains ever grown. The scent fills entire rooms and makes stealth growing nearly impossible without heavy carbon filtration.

Flavor: Tangy dairy funk upfront, earthy skunk mid-palate, cracked pepper and cream, with a diesel-like finish on the exhale. Some users detect sour berry notes and a cheesy-puff aftertaste. The savory funk lingers well after the session.

Effects & Experience

Onset: Quick — within minutes of inhalation, a noticeable mood lift and wave of cerebral euphoria. Tingling sensation around the eyes reported by many users.

Begins with uplifting, social, sativa-like head buzz that enhances creativity and conversation. Gradually transitions into a smooth, stress-melting body relaxation. Not immediately couch-locking but the indica side builds steadily. Munchies are common in the later phase. Leafly user data: 83% cerebral, 82% uplifting, 78% euphoric, 67% social, 62% relaxing.

Duration: Long-lasting — typically 2–3 hours. Users consistently note this is not a quick in-and-out buzz.

Growing Characteristics

Flower Time
8–9 weeks indoors (SeedFinder lists the original clone at ~48 days; most seed versions run 56–63 days)
Yield (Indoor)
400–550 g/m² (14–20 oz/m²) — high yielder with proper training
Yield (Outdoor)
500–625 g/plant (18–22 oz/plant); harvest late September to mid-October
Difficulty
Easy to Moderate — forgiving genetics with strong pest and mold resistance; main challenge is odor control
Height
Medium — 120–150 cm (4–5 ft) indoors; up to 180 cm (6 ft) outdoors untopped
Environment
Performs best indoors where temperature (70–80°F / 21–27°C) and humidity (40–50% veg, lower in flower) can be controlled. Thrives outdoors in warm, dry, temperate climates.

Grow Tips: Carbon filtration is NON-NEGOTIABLE — this is one of the smelliest strains in existence and the odor intensifies dramatically from week 6 onward. Responds extremely well to topping and LST; naturally bushy structure benefits from canopy opening to improve light penetration to lower sites. Keep humidity low in late flower — dense bud structure traps moisture and can invite mold if airflow is poor. Moderate to low stretch after flip makes it manageable in tents; plan for 1.5× stretch at most. Heavy nitrogen feeder in veg; taper nitrogen and boost P-K in flower. No exotic feeding requirements. The original clone roots aggressively from cuttings and clones very easily — a key reason it spread so successfully. Frosty trim is excellent for extraction due to strong trichome coverage on sugar leaves.

History & Origin

Around 1988–89, a grower in the Chiltern Hills of England germinated a pack of Skunk #1 seeds sourced from The Seed Bank (the Dutch precursor to Sensi Seeds, run by Sam 'the Skunkman'). One female exhibited an extraordinarily pungent, cheese-like aroma and dense bud structure that set it apart. The grower cloned it and began circulating cuttings through the UK underground. Around 1995, a clone reached the Exodus Collective — an alternative community and sound-system crew based at Haz Hall ('The Manor') on the outskirts of Luton. Exodus organised free parties, championed cannabis legalisation through their CANABIS campaign (Campaign Against Narcotic Abuse Because of Ignorance in Society), and grew Cheese prolifically. Cuttings 'flew out the door' to visitors, and the strain became the sonic and aromatic backdrop of the UK rave scene. After the Criminal Justice and Public Order Act of 1994 cracked down on raves, Exodus shifted to semi-legal events and community projects, but the Cheese clone's legend only grew. By 2000, 'Exodus Cheese' was as much a symbol of British counterculture as it was a cannabis variety. In the early 2000s, Milo Yung (Big Buddha Seeds) obtained the original Exodus clone via breeder Zorro of Red Eye Magazine. He crossed it with a pure Afghani male known as 'The Kali', backcrossed over two years, and released Big Buddha Cheese as the first-ever Cheese seed line in 2005. In 2006, Big Buddha Cheese won 1st Place Indica at the 19th High Times Cannabis Cup in Amsterdam, putting UK cannabis genetics on the global map.
