Fat Bastard
A heavy-yielding indica-dominant hybrid sold by multiple seedbanks, with murky lineage and a name that does most of the marketing.
Fat Bastard is a commercial seedbank strain marketed primarily on yield and potency. The lineage you'll see online (usually some mix of Bubba Kush and a Triangle Kush cross) is repeated by retailers but not independently verified — there's no breeder pedigree paper trail you can audit. No peer-reviewed studies exist for this specific cultivar. Treat published THC numbers, terpene claims, and effect descriptions as vendor marketing, not data. If you grow it, expect a typical indica-leaning hybrid; the rest is branding.
Overview
Fat Bastard is a commercial cannabis strain sold by several European seedbanks, including Weed Seeds Express and others, as a heavy-yielding indica-dominant hybrid [1]. Its market identity rests on two claims: high THC and big harvests. Beyond that, very little about Fat Bastard is independently documented. There is no peer-reviewed literature on the cultivar, no chemovar-level lab data published in scientific journals, and no breeder origin story with verifiable provenance.
Like most modern seedbank strains, the name functions as a brand. Different vendors may sell genetically distinct plants under the same name, a well-documented problem in the cannabis seed market Strong evidence[2].
Chemistry: cannabinoids and terpenes
Vendor pages typically list Fat Bastard at 18–27% THC with negligible CBD [1]. These numbers come from seller self-reporting, not standardized third-party testing across multiple harvests, so treat them as ballpark marketing figures Weak / limited.
The dominant terpene is usually reported as myrcene, with secondary caryophyllene and limonene [1]. No published chemovar analysis confirms this for Fat Bastard specifically. Broader research shows that terpene profiles vary substantially between phenotypes and grows of the same named strain Strong evidence[2][3], so a single 'profile' for Fat Bastard is misleading.
The popular claim that myrcene above 0.5% makes a strain 'indica' or sedating is folklore — it traces to a single uncited assertion that propagated through cannabis media and has no clinical backing Disputed[4].
Reported effects
Vendor and user-review sites describe Fat Bastard as relaxing, body-heavy, and euphoric, with common reports of couch-lock, appetite stimulation, and sleepiness at higher doses [1]. These are typical descriptors for any high-THC, myrcene-forward hybrid and largely reflect THC dose more than anything strain-specific Weak / limited.
There are no clinical trials on Fat Bastard. There are no controlled studies on any named seedbank cultivar's effects in humans No data. General cannabis pharmacology research [5] is the only evidence base that meaningfully applies, and it cannot predict what one named strain will do for one person.
Reported adverse effects mirror high-THC cannabis generally: dry mouth, dry eyes, dizziness, anxiety or paranoia at higher doses, and tolerance with repeated use Strong evidence[5].
Lineage (disputed)
Seedbanks variously describe Fat Bastard's parents as combinations involving Bubba Kush, Triangle Kush, and other OG-family genetics [1]. No breeder has published a verifiable pedigree. Different vendors give different ancestry, and there is no genetic testing data (e.g., from Phylos or independent labs) in the public record that would confirm or refute these claims No data.
This is the norm, not an exception. Genetic analyses of commercial cannabis have repeatedly found that strains sold under the same name are often unrelated, and that advertised parentage frequently does not match actual genetics Strong evidence[2]. Anyone buying Fat Bastard seeds from two different sources should expect potentially different plants.
Cultivation basics
Vendor descriptions of Fat Bastard suggest a forgiving, indica-leaning grow:
- Flowering time: roughly 8–9 weeks indoors [1].
- Structure: medium height, bushy, responsive to topping and LST.
- Yield: marketed as high — 500–600 g/m² indoor figures are common in vendor copy [1]. Actual yield depends overwhelmingly on light, environment, and grower skill, not on the strain name Strong evidence[6].
- Climate: prefers warm, dry conditions outdoors; finishes mid-to-late October in the Northern Hemisphere per vendor guides [1].
- Difficulty: sold as beginner-friendly.
None of these figures come from controlled cultivation trials. They are seller estimates, useful as rough planning numbers but not as guarantees.
Marketing vs. reality
What's marketing:
- The specific THC percentages on product pages (no independent multi-lot testing) Weak / limited.
- The lineage diagram (no verified pedigree) No data.
- The detailed 'effects' lists (no clinical data on this cultivar) No data.
- The implied promise that 'Fat Bastard' from any vendor is the same plant (it likely isn't) Strong evidence[2].
What's probably real:
- It's an indica-dominant hybrid that produces a typical high-THC, myrcene-forward experience.
- It grows like a fairly standard commercial photoperiod hybrid.
- It yields well for competent growers, like most modern commercial genetics.
If you want predictable chemistry, buy flower from a producer that publishes per-batch lab COAs. If you're buying seeds, accept that 'strain name' is a loose label, not a guarantee.
