Fat Bastard Auto Cannabis Seeds by Blimburn Seeds
Fat Bastard Auto is a fast-finishing autoflowering cannabis seed bred by Blimburn Seeds that delivers oversized, resin-drenched buds in just 10 weeks from germination. A three-way cross of Goldmember, Monkey Spunk, and a ruderalis cut, this 50/50 sativa-indica hybrid packs serious weight into a compact frame — up to 600 g/m² indoors. If you want fat, sticky flowers without a long wait, this is the seed to pop.
Pack Size
Fat Bastard Auto seeds come in packs of 3. That gives you enough to fill a small SOG setup or run a couple of plants with one spare in case of any germination hiccups.
Fat Bastard Auto Genetics and Lineage
Fat Bastard Auto gets its bulk from an unusual genetic cocktail. Blimburn Seeds crossed Goldmember — a resinous hybrid known for frosty output — with Monkey Spunk, a pungent cultivar that adds funk and vigour. A selected ruderalis cut was then bred in to lock down the autoflowering trait without sacrificing potency or yield. The result is a balanced 50/50 sativa-indica hybrid that flowers on its own clock, regardless of light schedule.
The name is a nod to the Austin Powers villain, and honestly, it fits. The buds this strain produces are thick, greasy, and unapologetically oversized. Dense calyxes stack tight and get blanketed in a shiny coat of trichomes that makes trimming a sticky affair. We've handled a lot of autoflower harvests over the years, and Fat Bastard Auto sits comfortably in the top tier for sheer bud density relative to plant size.
Growing Fat Bastard Auto Seeds
Fat Bastard Auto is one of the more forgiving autoflowers we carry, which makes it a solid pick if you're still finding your feet as a grower. Plants stay compact — maxing out around 150 cm — so they slot into smaller tents and balcony setups without trouble. Strong, sturdy branches mean you won't need to stake every cola, though a bit of low-stress training early on can open up the canopy and push yields even higher.
Indoors, expect up to 600 g/m² under good light. Outdoors, individual plants can pull around 300 g each. The compact, uniform growth habit makes Fat Bastard Auto a natural fit for Sea of Green (SOG) configurations — pack them in tight and let the canopy fill out evenly. Because she's an autoflower, there's no need to flip your light schedule. Just give her 18-20 hours of light from start to finish and she'll handle the rest.
One thing to watch: autoflowers don't bounce back from stress the way photoperiod plants do. If you overwater or overfeed in the first two weeks, you'll stunt the plant and lose yield you can't recover. Start light on nutrients and ramp up once she hits her stride in week three or four.

Aroma, Flavour, and Terpene Profile
Fat Bastard Auto is loaded with caryophyllene, myrcene, and humulene — a terpene trio that produces a bold, skunky aroma with sour fruit undertones. Crack open a cured jar and the first thing that hits you is a thick, dank funk. It's not subtle. If you're growing indoors without a carbon filter, your neighbours will know about it well before harvest day.
The flavour follows the nose: earthy skunk on the inhale, with a sour, slightly fruity tang on the exhale. It's the kind of profile that old-school smokers tend to love — none of that candy-sweet dessert strain character, just honest, pungent weed. Caryophyllene adds a peppery bite, myrcene brings the musky depth, and humulene rounds things out with a subtle herbal, almost hoppy quality.
Compared to something like Blimburn Seeds' other autoflowers, Fat Bastard Auto leans harder into that classic skunk territory. If you prefer your flower loud and funky rather than sweet and fruity, this is the one to grow.
Fat Bastard Auto Yield and Flowering Time
From the moment the seed cracks, you're looking at roughly 10 weeks to a finished harvest. That's fast, even by autoflower standards. Most growers see the first pistils appear around week 3, with the bulk of bud development happening between weeks 5 and 8. By week 9, trichomes should be clouding up nicely, and week 10 is typically chop time.
The yield numbers — up to 600 g/m² indoors and 300 g/plant outdoors — are ambitious but achievable with the right setup. Indoors, you'll want at least 400W of quality LED light over a 1 m² canopy, good airflow, and a consistent feeding schedule. In a SOG setup with 9-12 plants per square metre, individual plants stay smaller but the collective canopy fills out fast and maximises light use.
| Growing Environment | Expected Yield | Recommended Setup |
|---|---|---|
| Indoor (1 m²) | Up to 600 g/m² | SOG with 9-12 plants, 18-20h light |
| Outdoor (per plant) | Up to 300 g | Full sun, sheltered spot, max 150 cm height |
Why Fat Bastard Auto Stands Out
We've carried a lot of autoflowering seeds over the years, and the ones that keep selling are the ones that actually deliver on their promises. Fat Bastard Auto does. The 10-week turnaround is genuinely quick, the yields are above average for an auto, and the bud quality — dense, frosty, reeking of skunk — punches well above what most people expect from a ruderalis cross.
The honest limitation? She's not the most discreet plant to grow. That terpene profile is intense, and without proper odour control, you'll smell her through walls. If stealth is a priority, invest in a decent carbon filter before you even pop the seeds. The plant itself stays short and manageable, but the aroma is anything but low-profile.
Where Fat Bastard Auto really shines is in SOG setups. The uniform growth pattern means you get an even canopy without spending hours training individual plants. Pop 9 seeds into a 1 m² tent, keep conditions steady, and you'll have a wall of fat, sticky colas in just over two months. For the effort involved, the return is hard to beat.
Running Fat Bastard Auto in a SOG? Pair these seeds with a complete grow tent kit to get the light, ventilation, and carbon filtration sorted in one go. A quality grinder will also come in handy once those dense, resinous buds are cured and ready.
How to Grow Fat Bastard Auto Seeds
- Germinate your Fat Bastard Auto seeds using the paper towel method or by placing them directly into a moist, pre-prepared growing medium. Taproots typically emerge within 24-72 hours.
- Transplant sprouted seeds into their final container straight away — autoflowers don't like being repotted. A 10-15 litre pot with well-draining soil or coco coir works well.
- Set your lights to an 18/6 or 20/4 schedule from day one. Fat Bastard Auto doesn't need a light flip to start flowering, so keep the hours consistent throughout the entire grow.
- Go easy on nutrients for the first 2 weeks. Autoflowers are sensitive to overfeeding early on. Start at half the recommended dose and increase gradually as the plant enters its vegetative growth phase around week 2-3.
- Watch for the first pistils around week 3. Once flowering begins, switch to a bloom-focused nutrient mix and maintain steady environmental conditions — 20-26°C with relative humidity around 40-50%.
- During weeks 5-8, buds will bulk up rapidly. Support heavy colas if needed and ensure good airflow through the canopy to prevent mould in those dense flower clusters.
- Begin checking trichomes with a jeweller's loupe from week 9. Harvest when the majority of trichomes have turned milky white with a few amber heads — typically around week 10.
- Dry your harvest in a dark, well-ventilated space at 18-21°C for 7-10 days, then cure in airtight jars for at least 2 weeks. The skunky, sour fruit terpene profile develops further with a proper cure.
Frequently Asked Questions
Is Fat Bastard Auto suitable for beginner growers?
Yes. Fat Bastard Auto is hardy, compact, and doesn't require light schedule changes. Keep nutrients light in the first fortnight and you'll avoid the most common beginner mistakes. The uniform growth habit means less fiddly training is needed compared to many photoperiod strains.
How long does Fat Bastard Auto take from seed to harvest?
Roughly 10 weeks from germination to harvest. Most growers see the first flowers appear around week 3, with the plant reaching full maturity by week 10. That's one of the fastest turnarounds you'll find for a strain with this kind of yield potential.
Can I grow Fat Bastard Auto indoors and outdoors?
Both work well. Indoors, she thrives under 18-20 hours of light and yields up to 600 g/m². Outdoors, expect up to 300 g per plant. The 150 cm max height keeps her manageable in either environment.
What does Fat Bastard Auto smell and taste like?
Expect a strong skunky aroma with sour fruit undertones, driven by caryophyllene, myrcene, and humulene. The flavour is earthy and pungent with a peppery, slightly fruity exhale. A carbon filter is strongly recommended for indoor grows — this strain is loud.
What yield can I expect from Fat Bastard Auto?
Up to 600 g/m² indoors in an optimised SOG setup, or around 300 g per plant outdoors. Actual yields depend on light quality, nutrients, and growing conditions, but the genetics are built for heavy production.
Is Fat Bastard Auto good for SOG setups?
It's one of the best autos we'd recommend for SOG. The compact size, uniform growth, and strong branching mean you can pack 9-12 plants per square metre and get an even, productive canopy without extensive training.
What are the dominant terpenes in Fat Bastard Auto?
Caryophyllene (peppery, spicy), myrcene (earthy, musky), and humulene (herbal, hoppy). This combination produces the strain's signature dank, skunky profile with sour fruit notes underneath.
