Fat Bastard
Commercial indica-dominant hybrid with high THC and disputed parentage.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
Fat Bastard is a seedbank brand, not a stable genetic line. Different vendors sell plants with the same name that may be genetically unrelated. The THC percentages are vendor estimates, not independently verified. There's no peer-reviewed research on this cultivar, so effects are anecdotal. It grows like a standard commercial hybrid. Buy from a vendor you trust, and don't expect consistency across seed batches.
Overview
Fat Bastard is a commercial cannabis strain sold primarily by European seedbanks, including Weed Seeds Express, marketed as a heavy-yielding indica-dominant hybrid. Its commercial identity rests on two claims: high THC content and substantial harvests. Beyond vendor descriptions, very little about Fat Bastard is independently documented. There is no peer-reviewed literature on this 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 rather than a stable genetic designation. Different vendors may sell genetically distinct plants under the same name — a well-documented problem in the cannabis seed market Strong evidence[1]. This means a Fat Bastard from one seedbank may be a different plant from a Fat Bastard from another.
Chemistry: Cannabinoids and Terpenes
Vendor product pages typically list Fat Bastard at 18–27% THC with negligible CBD. These numbers come from seller self-reporting, not standardized third-party testing across multiple harvests or growing seasons, so treat them as marketing estimates rather than independent confirmation Weak / limited.
The reported dominant terpene is myrcene, with secondary peaks of caryophyllene and limonene. No published chemovar analysis independently confirms this profile for Fat Bastard. Broader research shows that terpene profiles vary substantially between phenotypes and grows of the same named strain Strong evidence[2][3], so a single 'typical' profile for Fat Bastard is inherently misleading.
The popular claim that myrcene above 0.5% produces sedation or 'indica' effects is folklore with no clinical basis — see The Myrcene 0.5% Threshold for the full story Disputed[4].
Reported Effects
Vendor sites and user-review platforms describe Fat Bastard as relaxing, body-heavy, and euphoric, with common user reports of couch-lock, appetite stimulation, and sleepiness at higher doses. These are typical descriptors for any high-THC, myrcene-forward hybrid and largely reflect THC dose rather than anything unique to this particular strain name Weak / limited.
There are no clinical trials on Fat Bastard. In fact, there are no controlled studies on any named seedbank cultivar's subjective effects in humans No data. General cannabis pharmacology research [5] is the only evidence base available, and it cannot predict what a specific named strain will produce in a specific person.
Reported adverse effects match high-THC cannabis generally: dry mouth, dry eyes, dizziness, anxiety or paranoia at higher doses, and tolerance with repeated use Strong evidence[5].
Lineage and Genetics
Seedbanks variously describe Fat Bastard's parents as combinations involving Bubba Kush, Triangle Kush, and other OG-family genetics. No breeder has published a verifiable pedigree. Different vendors give different ancestry claims, and there is no genetic testing data (for example, from Phylos or independent labs) in the public record that would confirm or refute these ancestries No data.
This is the norm in the commercial cannabis market, not an exception. Genetic analyses of commercial cannabis have repeatedly found that strains sold under the same name are often genetically unrelated, and that advertised parentage frequently does not match actual genetics when tested Strong evidence[1]. Anyone buying Fat Bastard seeds from two different sources should expect potentially distinct plants.
Growing Fat Bastard
Vendor descriptions characterize Fat Bastard as a relatively forgiving, indica-leaning grow:
- Flowering time: roughly 8–9 weeks indoors.
- Structure: medium height, bushy, responsive to topping and low-stress training (LST).
- Yield: marketed as high — 500–600 g/m² indoor figures are common in vendor copy. In practice, yield depends overwhelmingly on light intensity, environment, nutrient regimen, and grower skill, not on strain name Strong evidence[6].
- Climate: prefers warm, dry conditions outdoors; typical finishing window is mid-to-late October in the Northern Hemisphere per vendor guides.
- Difficulty: marketed as beginner-friendly.
None of these figures come from controlled cultivation trials. They are seller estimates, useful as rough planning numbers but not as performance guarantees. Actual results will vary based on setup and technique.
Marketing vs. Reality
What's marketing:
- The specific THC percentages on product pages (no independent multi-batch testing) Weak / limited.
- The lineage diagram (no verified breeder pedigree) No data.
- The detailed 'effects' lists (no clinical data on this cultivar) No data.
- The implicit promise that 'Fat Bastard' from any vendor is the same plant (it likely isn't) Strong evidence[1].
What's probably real:
- It's an indica-dominant hybrid that typically produces a 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 results. If you're buying seeds, accept that 'strain name' is a loose marketing label, not a genetic guarantee. For more context, see The Indica/Sativa Myth.
Frequently Asked Questions
Is Fat Bastard an indica or sativa? It's marketed as indica-dominant. However, the indica/sativa distinction doesn't reliably predict effects. See The Indica/Sativa Myth for why.
How much THC does Fat Bastard have? Vendors claim 18–27% THC. These are self-reported estimates, not independently verified per batch. Actual THC will vary by grow, phenotype, and harvest timing. If you buy flower, look for a Certificate of Analysis (COA) from a third-party lab.
What's the flowering time? Approximately 8–9 weeks indoors, per vendor guidance. Outdoors, typically mid-to-late October in the Northern Hemisphere.
Who actually bred Fat Bastard? Unknown. No breeder has published a verifiable origin or pedigree. Different seedbanks attribute different parentage, and there's no genetic testing data to settle the claim.
