Fat Bastard Cannabis Seeds by Blimburn Seeds
Fat Bastard seeds produce an indica-dominant hybrid with THC levels tested between 30% and 38%, making this one of the most potent feminised strains available to buy from Blimburn Seeds. The cross brings together two heavy hitters — Goldmember and Monkey Spunk — and the yields match the attitude: up to 900 g per plant outdoors, or 400–600 g/m² indoors under optimised conditions. If you want a strain that fills jars and then knocks you sideways when you open them, Fat Bastard earns its name.
The genetics here tell an interesting story. Goldmember contributes the indica-dominant structure — stocky, vigorous plants with dense branching and that unmistakable pungent, old-school funk. Monkey Spunk brings skunky berry flavours and a more energising edge to the effects. The result is a hybrid that leans indica in growth habit but delivers a surprisingly balanced experience: an initial lift that sharpens focus, followed by a full-body relaxation that settles in gradually. Stick your nose in a cured jar and you get waves of skunk and fuel, broken up by citrus undertones that genuinely refresh the palate. It smells like a coffeeshop in 2003 — in the best possible way.
Fat Bastard Genetics and Growth Characteristics
Fat Bastard is a feminised photoperiod cross of Goldmember and Monkey Spunk, bred by Blimburn Seeds for maximum resin production and structural vigour. The plants respond well to a range of growing environments. Blimburn Seeds recommends the paper towel method for germination, consistent nutrition throughout the full life cycle, and plenty of light — these aren't fussy plants, but they reward good care with genuinely impressive results.
Indoors, expect a flowering time of 8–10 weeks. The plants develop dense, resin-caked colas that stack weight quickly in the final weeks. At 400–600 g/m², yields are well above average for an indoor photoperiod strain. Outdoors, the numbers get properly exciting: up to 900 g per plant, with harvest landing around mid-October in the Northern Hemisphere. That kind of output means you need to plan your drying space before you plant — we've seen growers underestimate how much bud a single Fat Bastard can throw out.
One honest limitation: with THC levels this high, the flowers can be extremely sticky during trimming. Budget extra time (and a jar of isopropyl alcohol for your scissors). The resin production is a sign of quality, but it does make processing slower than a less trichome-heavy variety.

Fat Bastard Flowering Time and Yield
Fat Bastard flowers in 8–10 weeks indoors and is ready for outdoor harvest around mid-October, placing it in a comfortable middle ground — not the fastest finisher, but far from a marathon strain. The extra week or two compared to a quick 7-week variety pays off in density and resin coverage. If you're growing indoors under a 600W HPS or equivalent LED, the 400–600 g/m² range is realistic with proper training techniques like LST or ScrOG.
Outdoors is where Fat Bastard really flexes. The 900 g per plant figure assumes a long vegetative period, good soil, and a climate that stays dry enough through October to avoid mould issues. In a Mediterranean or similarly warm climate, these plants can become absolute trees. In northern Europe, a greenhouse or polytunnel helps protect those massive colas from autumn rain — losing a 900 g plant to bud rot in the final week is a pain we wouldn't wish on anyone. According to EMCDDA data on European cannabis potency trends, strains consistently testing above 25% THC remain uncommon in lab-verified samples, which puts Fat Bastard's 30–38% range in genuinely rare territory.
Compared to something like Royal Gorilla or similar high-THC strains, Fat Bastard offers a meaningfully higher yield ceiling. Where Royal Gorilla typically tops out around 500 g/m² indoors, Fat Bastard pushes to 600 g/m² with the right setup — and the outdoor gap is even wider. If output matters to you as much as potency, this is one of the best options in the Blimburn Seeds catalogue.
Fat Bastard Aroma, Flavour, and Terpene Profile
Fat Bastard's terpene profile is dominated by myrcene, limonene, and caryophyllene, producing a deep skunky funk layered with genuine citrus brightness. That pungent, almost acrid base coats the inside of your nose and lingers on your fingers after handling the buds. Underneath the skunk, there's a proper lemon-zest note that cuts through the heaviness and lifts the whole aroma.
When smoked or vaped, the flavour follows the nose closely. The inhale carries the skunky, slightly earthy base, and the exhale opens up into citrus and a faint berry sweetness inherited from the Monkey Spunk parent. The smoke is thick and resinous — you can feel the potency before the effects even arrive. If you've been growing modern cookie or gelato crosses and miss that classic, room-clearing dankness, Fat Bastard brings it back with force.
A carbon filter is non-negotiable if you're growing this strain indoors. The smell during late flowering is intense enough to announce itself through walls and doors. We'd pair this with a proper extraction setup rated for your tent size — don't cheap out on the filter with a strain this loud.
How to Grow Fat Bastard Seeds
Fat Bastard seeds germinate best using the paper towel method at 22–25°C, with taproots typically emerging within 24–72 hours. Follow these steps for a successful grow from seed to harvest:
- Germinate using the paper towel method: place seeds between damp (not soaking) paper towels on a plate, cover with a second plate, and keep at 22–25°C. Taproots typically emerge within 24–72 hours.
- Transfer sprouted seeds to small pots with light, airy growing medium. Keep humidity high (65–70%) and temperatures stable during the seedling stage.
- Transition to vegetative growth under 18/6 light. Fat Bastard responds well to low-stress training — bend and tie branches early to create an even canopy and maximise light penetration.
- Provide consistent nutrition throughout veg and flower. A balanced NPK feed during veg, switching to a bloom-focused formula with higher phosphorus and potassium once you flip to 12/12.
- Flip to 12/12 light when plants have filled your desired canopy space. Flowering takes 8–10 weeks — monitor trichomes with a jeweller's loupe and harvest when most are milky with some amber.
- Outdoors, plant after the last frost and allow a full vegetative season. Support heavy branches with stakes or netting as buds develop. Harvest around mid-October.
- Dry in a dark, well-ventilated space at 18–21°C and 55–60% humidity for 7–14 days. Cure in glass jars for at least 2–4 weeks, burping daily for the first week.
Why Buy Fat Bastard Seeds for Your Next Grow
Fat Bastard delivers one of the highest combinations of THC potency and yield available in feminised seed form today. The cannabis seed market is saturated with strains claiming 30%+ THC. Most of them are marketing fluff. Fat Bastard backs up the numbers with genetics that have been specifically bred for resin production and potency — the Goldmember x Monkey Spunk cross wasn't accidental, and Blimburn Seeds have a track record of delivering on their stated figures.
What sets this strain apart from other high-THC options isn't just the potency — it's the combination of potency and yield. Plenty of strains will test high but produce modest harvests. Fat Bastard gives you both: up to 900 g per plant outdoors and 400–600 g/m² indoors, all coated in trichomes. For growers who want to maximise both quantity and quality from a single run, this is one of the strongest choices available. If you're looking to order seeds that genuinely deliver on big claims, Fat Bastard belongs at the top of your shortlist.
The effects lean hybrid despite the indica-dominant genetics. Users report an initial energy boost and mood lift from the Monkey Spunk influence, followed by a gradual physical relaxation that doesn't immediately glue you to the sofa. It's a versatile smoke — functional enough for a late afternoon session, heavy enough to wind down with in the evening. The 30–38% THC range means experienced users get what they're after, but newcomers should approach with genuine respect. A single puff goes a long way at this concentration.
Growing Fat Bastard indoors? A ScrOG net helps distribute those heavy colas evenly and maximises your g/m² return. Pair with a quality carbon filter — the skunk aroma on this strain will test any budget option. For nutrients, BioBizz Bloom works well during the flowering phase to support those dense buds. If you're after another heavy-yielding Blimburn Seeds variety to run alongside, get their Sitka feminised seeds for a complementary grow with different terpene profiles. Growers who enjoy classic skunk genetics might also appreciate Sensi Seeds Skunk #1 for a side-by-side comparison of old-school flavour.
Frequently Asked Questions
What does Fat Bastard taste like?
Fat Bastard delivers a thick, skunky smoke with prominent citrus notes on the exhale. There's a subtle berry sweetness underneath, inherited from its Monkey Spunk parent. The flavour is old-school and pungent — if you enjoy classic dank strains over modern dessert genetics, this one hits the mark.
How long does Fat Bastard take to flower?
Fat Bastard flowers in 8–10 weeks indoors under a 12/12 light cycle. Outdoors, plants are ready for harvest around mid-October in the Northern Hemisphere. Monitor trichome colour with a loupe to dial in your preferred harvest window.
Is Fat Bastard suitable for beginner growers?
Fat Bastard is adaptable and vigorous, which helps less experienced growers. The main challenge is managing the heavy colas in late flower — they may need support — and controlling the intense smell. If you have a decent setup with a carbon filter and some patience, it's manageable as a first or second grow.
How much does Fat Bastard yield indoors?
Blimburn Seeds states 400–600 g/m² indoors with an 8–10 week flowering period. Achieving the upper end of that range typically requires training techniques like ScrOG or LST, strong lighting, and consistent feeding throughout the cycle.
Why is the THC so high on Fat Bastard?
The 30–38% THC range comes from the Goldmember x Monkey Spunk cross — both parents were selected for resin production and potency. Actual THC levels depend on your growing conditions, but the genetic ceiling on this strain is genuinely among the highest available in feminised seed form.
Does Fat Bastard smell a lot during flowering?
Yes, intensely. The skunky, pungent terpene profile means this strain produces a strong odour from mid-flower onwards. A properly sized carbon filter and extraction fan are non-negotiable for indoor grows. Without them, the smell will travel well beyond your grow space.
What are the effects of Fat Bastard?
Users report an initial mood lift and energy boost, followed by a gradual full-body relaxation. Despite being indica-dominant, the hybrid genetics keep it from being immediately sedating. At 30–38% THC, the effects are strong and fast-acting — start slow if you're not accustomed to high-potency strains.
