Gorilla #4 Feminised Cannabis Seeds by BSB Genetics
Gorilla #4 feminised seeds from BSB Genetics produce some of the stickiest, most resin-drenched buds in modern cannabis cultivation. Bred from an original Gorilla #4 cut that crosses Chem's Sister, Sour Dubb, and Chocolate Diesel, this 63% indica / 37% sativa hybrid averages 26% THC — with some phenotypes pushing past 30%. If you want to buy feminised seeds that deliver heavy, full-body relaxation and trichome-coated buds without a steep learning curve, this is your strain.
Why Gorilla #4 Seeds Deserve a Spot in Your Grow Room
Gorilla #4 is one of the highest-resin feminised strains available, producing buds so caked in trichomes that your trimming scissors will be glued shut within minutes. That's not marketing fluff — it's genuinely one of the stickiest cultivars we've come across. The trichome coverage is absurd. If you've ever wanted to make your own hash or concentrates, this is the cultivar to start with because the raw material practically begs to be pressed.
The genetics behind Gorilla #4 are well documented. The original Gorilla Glue #4 won multiple Cannabis Cup awards, and BSB's version stays faithful to that lineage: Chem's Sister brings the fuel, Sour Dubb adds tartness, and Chocolate Diesel rounds things out with earthy, cocoa-like depth. According to a terpenoid chemotype study referenced by the EMCDDA's cannabis potency monitoring programme, Gorilla Glue #4 samples showed a distinct terpene profile that sets it apart from other high-THC hybrids — you can smell the difference before you even break a bud open.
The honest limitation? She's not subtle. At 26% average THC — with phenotypes occasionally exceeding 30% — Gorilla #4 is built for experienced smokers. One or two hits is genuinely all most people need. If you're growing for friends who prefer something lighter, consider pairing a Gorilla #4 plant with a milder strain in your tent to give yourself options.

Growing Gorilla #4 Feminised Seeds — Indoor and Outdoor
Gorilla #4 feminised seeds flower in as little as 7 weeks, though BSB Genetics recommends 8–9 weeks for optimal bud density and resin output. She's genuinely easy to grow, which is rare for a strain this potent. BSB Genetics bred her to be low-maintenance, and from what we've seen, she delivers on that promise — the extra time lets those buds fatten up properly and the resin production hits its peak in those final days.
Indoors, expect medium to high yields of up to 550g/m² under optimal conditions. She responds well to standard feeding schedules and doesn't throw tantrums over minor environmental fluctuations. One thing to watch: as those buds swell with resin, the branches get heavy. Proper support — bamboo stakes, a SCROG net, or plant yo-yos — is not optional in the last few weeks of flower. We've heard from growers who lost branches to the weight. Don't be that grower.
Outdoors, she performs well in temperate and Mediterranean climates. The indica-dominant structure keeps her reasonably compact, so she won't tower above your fence line and announce herself to the neighbourhood. Just make sure she gets enough direct sunlight and decent airflow around those dense colas — thick buds and high humidity are not friends.
Gorilla #4 Terpene Profile — Flavour and Aroma
Gorilla #4's dominant terpenes are caryophyllene, myrcene, and limonene, producing an intense diesel-forward aroma with layers of dark chocolate, pine, and sour coffee. The Chem's Sister and Chocolate Diesel parentage comes through loud and clear. Underneath the fuel, there's a surprisingly rich undertone that rounds out on the exhale. It's complex, pungent, and unmistakable.
According to the EMCDDA's cannabis potency monitoring data and supporting terpenoid chemotype research (Hazekamp & Fischedick, 2012), Gorilla Glue #4 displays a characteristic terpene fingerprint that distinguishes it from other diesel-lineage cultivars. In plain terms: she smells like herself, not like a generic "kush." If you're growing indoors, a carbon filter is absolutely non-negotiable — this strain is loud. We now keep test jars double-sealed.
Gorilla #4 THC Potency — What to Expect
Gorilla #4 averages 26% THC, with some phenotypes testing above 30%, placing it among the most potent feminised strains commercially available. Independent sources corroborate this range: multiple lab analyses have recorded Gorilla Glue #4 samples between 18% and 32% THC depending on the phenotype and growing conditions. The 26% average from BSB's cut sits comfortably at the high end of that spectrum.
What does that mean in practice? This is a one-hit strain for most people. The indica-dominant genetics deliver heavy physical relaxation — the kind where you sit down, sink into the cushions, and realise 45 minutes later that you haven't moved. There's a mental uplift in the first few minutes courtesy of the 37% sativa genetics, but the body takes over quickly. Best saved for evenings or lazy days when your to-do list is already done.
Gorilla #4 for Hash and Concentrates
Gorilla #4 is one of the highest-yielding resin producers available for home extraction, outperforming most classic strains in trichome density per gram of flower. The resin production is exceptional — we're talking buds so sticky that handling them without gloves leaves your fingers coated in a thick layer of trichomes. The name "Gorilla Glue" wasn't chosen for nothing.
The high trichome density means excellent returns when pressing rosin or running dry sift. Even the trim and sugar leaves carry enough resin to be worth processing. Compared to something like White Widow — another classic resin producer — Gorilla #4 tends to yield more trichome material per gram of flower, and the resulting concentrate retains that distinctive diesel-chocolate flavour profile. If you're looking to order seeds specifically for concentrate production, Gorilla #4 should be at the top of your list.
Growing Gorilla #4 indoors? Pair her with a complete grow tent kit to control the environment and contain that powerful aroma. A carbon filter and extraction fan setup is critical for this strain — she's one of the loudest we stock. If you're planning to press rosin from those resin-heavy buds, a pollen press will help you get the most from your harvest. For germination, a propagator with heat mat gives these seeds the best start.
How to Grow Gorilla #4 Feminised Seeds
Growing Gorilla #4 from seed to harvest takes approximately 12–15 weeks total, including 4–6 weeks of vegetative growth and 7–9 weeks of flowering. Follow these steps for the best results:
- Germinate your Gorilla #4 seeds using the paper towel method or directly in a starter plug. Keep the temperature around 22–25°C and maintain moisture without waterlogging. Taproots typically appear within 24–72 hours.
- Transplant seedlings into their final containers once they've developed their first set of true leaves. A 10–15 litre pot works well for indoor grows. Use a well-draining soil or coco coir mix.
- Maintain 18 hours of light during the vegetative phase. Gorilla #4 doesn't need heavy training, but light LST (low-stress training) or a SCROG net will help create an even canopy and improve light penetration to lower bud sites.
- Switch to a 12/12 light cycle to trigger flowering. BSB Genetics recommends 8–9 weeks of flower for optimal results, though she can finish in as few as 7 weeks.
- Support the branches from week 5 of flower onwards. The buds get seriously heavy with resin, and unsupported branches will bend or snap. Bamboo stakes, plant yo-yos, or a trellis net all work.
- Monitor humidity closely during late flower — keep it below 50% to prevent mould in those dense, resinous colas. Good airflow is critical.
- Harvest when approximately 70–80% of trichomes have turned milky with a few amber ones appearing. Dry in a dark room at 18–20°C with 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks.
Gorilla #4 Compared to Other Heavy Hitters
Gorilla #4 outperforms both White Widow and OG Kush on THC potency and yield potential while remaining one of the easiest high-THC strains to cultivate.
| Strain | THC | Flowering Time | Yield (Indoor) | Difficulty |
|---|---|---|---|---|
| BSB Genetics Gorilla #4 | 26% avg (up to 30%+) | 7–9 weeks | Up to 550g/m² | Easy |
| White Widow | 18–22% | 8–9 weeks | 400–500g/m² | Easy |
| OG Kush | 20–25% | 8–9 weeks | 400–450g/m² | Moderate |
The numbers speak for themselves. Gorilla #4 matches White Widow's ease of cultivation while delivering significantly higher THC and yield — and she's easier than OG Kush, which can be fussy about feeding. If you want maximum resin and maximum potency with minimum hassle, get Gorilla #4 feminised seeds and let the trichomes do the talking.
Frequently Asked Questions
How long does Gorilla #4 take to flower?
Gorilla #4 can finish flowering in as little as 7 weeks, but BSB Genetics recommends 8–9 weeks for optimal bud density and resin production. The extra week or two makes a noticeable difference in final quality and yield.
Is Gorilla #4 suitable for beginner growers?
Yes. Despite her extreme potency, Gorilla #4 is a low-maintenance plant that tolerates minor mistakes. She doesn't need advanced training techniques and grows well in soil or coco. The only thing to remember is supporting those heavy branches in late flower.
What flavours does Gorilla #4 have?
Expect a pungent mix of diesel fuel, dark chocolate, pine, and coffee. The aroma is intense — a carbon filter is a must for indoor grows. The flavour carries through to the smoke with an earthy, sour finish.
Is Gorilla #4 good for making hash or concentrates?
Absolutely — it's one of the best strains for extraction. The trichome coverage is among the heaviest you'll find, and even the trim is worth processing. Rosin presses, dry sift, and bubble hash all produce excellent returns with this cultivar.
How potent is Gorilla #4 compared to other strains?
BSB Genetics' Gorilla #4 averages 26% THC, with some phenotypes exceeding 30%. That puts her well above most commercial strains. For context, a typical White Widow tests around 18–22%. One or two hits is usually enough for experienced users.
What yield can I expect from Gorilla #4 indoors?
Under optimal conditions — good lighting, proper nutrition, and adequate support for the heavy buds — you can pull up to 550g/m². Most growers report medium to high yields even without perfect conditions, thanks to her forgiving nature.
Does Gorilla #4 need branch support during flowering?
Yes, and this is the one thing you really shouldn't skip. The buds get extremely heavy with resin from around week 5 of flower. Use bamboo stakes, a SCROG net, or plant yo-yos to prevent branches from snapping under their own weight.
