Fat Bastard Auto | Blimburn Seeds – High THC, Fast Autoflowering Strain for Big Yields

Fat Bastard Auto by Blimburn Seeds is a high-THC autoflowering powerhouse that delivers massive yields, rock-hard buds, and a balanced 50% Indica / 50% Sativa experience—all in just 8 to 10 weeks from seed to harvest. This is cannabis excellence, simplified.

Are cheap or underperforming seeds holding you back?

Let’s be real: not all seeds are created equal. Picking low-quality genetics means weak plants, low resin, and disappointing harvests. You end up wasting money, time, and energy on crops that barely cover your costs—let alone deliver that knockout punch you’re after.

What’s the real cost of choosing poorly?

It’s not just about the price tag. It’s the frustration of watching your plants struggle. It’s the wasted nutrients, the failed germination, the mold outbreaks, and the harvests that leave you asking, “Was this even worth it?” You’re not just losing grams—you’re losing confidence in your grow.

Fat Bastard Auto: premium performance that earns its place

Fat Bastard Auto isn’t just another autoflower—it’s a high-efficiency machine built for serious results. With THC levels hitting 30–38%, yields up to 600 g/m² indoors and 300 g/plant outdoors, and rock-solid resistance, it pays for itself in quality, potency, and consistency. This is the kind of seed that turns skeptics into believers.

What this strain brings to your daily grind

Imagine finishing your day with a bud that actually delivers—smooth, flavorful, and potent enough to melt stress without locking you to the couch. Fat Bastard Auto gives you that balance: euphoric lift at the start, deep relaxation by the end. Whether you're unwinding solo or sharing with friends, it’s the kind of smoke that feels earned. Plus, its fast cycle means you’re never without—plant one, harvest in 10 weeks, and start the next. It’s self-sustaining excellence.

Format, lifespan and efficiency

As an autoflower, Fat Bastard Auto runs on its own clock—no light cycle tricks, no guesswork. From germination to harvest in 8–10 weeks, it’s built for speed and reliability.

• Autoflowering cycle: 8–10 weeks (germination to harvest)
• Indoor yield: 400–600 g/m² (1.31–1.97 oz/ft²)
• Outdoor yield: 125–300 g/plant (4.41–10.58 oz/plant)
• Height: up to 1.5 m (4.92 ft), compact and bushy
• Maximize output by planting directly in final pot (3–5 gallons / 11–19 L)
• Use low-stress training (LST) early to open canopy and boost light exposure
• Keep humidity at 40–50% during flowering to prevent mold and boost resin

Advantages and benefits in terms of quality–price ratio

• High THC (30–38%) means less product needed per session—longer-lasting effects, better value
• Massive yields mean more bud per square foot—ideal for small spaces with big ambitions
• Fast 8–10 week cycle allows multiple harvests per season—stack your stash faster
• 50% Indica / 50% Sativa balance delivers both mental clarity and body relaxation—versatile for day or night
• Fruity-skunk terpene profile (myrcene, caryophyllene, humulene) enhances flavor and smoothness
• Resilient genetics resist mold and pests—fewer losses, more confidence
• Easy to grow—perfect for beginners but rewarding for experts
• Consistent phenotypes mean reliable results every time

Tricks to get the most out of it without overspending

Get premium results without blowing your budget. Start with a quality soil mix—like Soil Grow—to give roots a strong foundation. Use LST instead of topping to avoid stressing the plant. And don’t overfeed—autoflowers prefer light, steady nutrients. A little goes a long way.

• Germinate in a warm, dark place (21–26 °C / 70–79 °F) with moist paper towels
• Plant directly in final pot (3–5 gal / 11–19 L) to avoid transplant shock
• Use 18–20 hours of light daily—no need to switch to 12/12
• Add a root booster like Pro Roots at transplant for faster establishment
• Flush 7–10 days before harvest for smoother smoke and cleaner flavor

Personal Experience of Pevgrow’s CEO (Alan)

Fat Bastard Auto is one of those rare autos that actually lives up to the hype. I’ve tested dozens of high-THC autos, but this one stands out because it doesn’t sacrifice quality for speed. I grew it in my 1.2 x 1.2 m tent under a 600W LED, 18/6 light cycle, in 18L pots with Soil Grow and a bit of perlite. I used LST early to spread the canopy and got 580 g from three plants—dry, cured, and absolutely frosty.

What sold me? The flavor. It’s not just skunk—it’s sweet, earthy, with a citrus kick when you break it open. And the high? Perfect balance. I can smoke it after work and still function, but it’s strong enough to knock me out if I overdo it. For the price, especially with the 1+1 free deal, it’s a no-brainer. My tip: don’t overfeed it. Let the genetics do the work. And definitely flush—it makes a huge difference in smoothness.
