GG#4 Auto Seeds by BSF Seeds — Sticky Autoflowering Genetics
GG#4 Auto is an autoflowering feminised cannabis seed that delivers the resin-drenched, heavy-hitting character of the original Gorilla Glue #4 in a compact, fast-finishing package. BSF Seeds from Spain crossed an elite GG#4 clone with their own third-generation autoflowering genetics, and the result is a plant that practically grows itself — medium height, low maintenance, and absolutely caked in trichomes. If you've ever handled GG#4 bud and had your fingers stick together like you'd grabbed a glue trap, you know exactly what this lineage is about.
This is the auto we'd point you towards if you want serious resin production without babysitting a photoperiod plant through light schedule changes. Sixty-five days from germination to harvest. That's it. Pop the seed, keep her fed and lit, and she'll reward you with dense, frosted flowers that smell like a diesel pump parked in a pine forest.
GG#4 Auto Variant and Pack Size
GG#4 Auto is available in a single pack of 4 feminised autoflowering seeds. Every seed is female — no males to cull, no sexing required. Four seeds gives you enough for a solid SOG setup or a couple of outdoor pots with spares in the fridge for next season.

Why GG#4 Auto Seeds Deserve a Spot in Your Grow
The original Gorilla Glue #4 became a West Coast legend for one reason above all else: resin. The buds produce so much sticky trichome coverage that trimming becomes an event — scissors gumming up every few snips, fingers coated in a layer of hash-like residue. BSF Seeds managed to carry that trait into this autoflowering version without diluting it into something forgettable. We've seen a lot of autos that trade potency and frost for speed, but GG#4 Auto isn't one of them.
The 65-day seed-to-harvest cycle is genuinely fast. For context, most photoperiod strains need 8–10 weeks of flowering alone, plus a month or more of veg. Here you're looking at roughly 9 weeks total. Indoor growers pulling 500g/m² from an auto in that timeframe are getting exceptional value per day of electricity. Outdoors, 300g per plant is solid — especially from a plant that doesn't care about light cycles and will flower under any schedule from 12 to 24 hours of light.
The one honest limitation: like most autos, she doesn't respond well to high-stress training early on. There's no time to recover from mistakes when the clock is already ticking. BSF Seeds does note she takes well to topping and SOG, but you'll want to top early — around the 3rd or 4th node — and only if the plant looks vigorous. If she's growing slowly for any reason, leave her alone and let her do her thing. Compared to a photoperiod GG#4 where you can veg for as long as you like to recover from training stress, the auto version demands a lighter touch.
Growing GG#4 Auto — What to Expect
This strain is genuinely low-maintenance. She grows to a medium height, which means she fits comfortably in an 80x80 or 100x100 tent without stretching into your lights. The indica-dominant structure keeps internodal spacing tight, producing a bushy plant with multiple bud sites — ideal for SOG setups where you pack several plants into a small footprint.
Experienced growers will appreciate how well she responds to Sea of Green. Plant 4–9 per square metre, keep them on 20/4 or 18/6 light, and you'll get a canopy of dense, uniform colas. The resin production really kicks in during the final 2–3 weeks — that's when you'll start noticing the sticky, gluey trichomes the strain is named for. A carbon filter is non-negotiable from week 5 onwards; the diesel and pine terpenes are pungent.
One thing we'd flag: because of the extreme resin output, GG#4 Auto is more susceptible to bud rot in humid conditions than less frosty strains. Keep your relative humidity below 50% during late flower. If you're growing outdoors, harvest promptly when trichomes turn milky — don't leave her out in autumn rain hoping for a few extra grams.
Flavour, Aroma, and Resin Profile of GG#4 Auto
Crack open a cured bud and you'll get hit with diesel first — sharp, fuel-like, unmistakable. Underneath that sits a base of damp earth and sweet, woody pine that rounds out the nose. It's not a subtle smell. Your grinder will reek of it for days.
The terpene profile leans heavily on myrcene, caryophyllene, and limonene. According to a study published in PMC, beta-myrcene in particular stands out for its significant anti-inflammatory properties as observed in human chondrocyte research (PMC11085560). That terpene combination is also what gives the smoke its layered character — the pine sweetness on the inhale, the diesel bite on the exhale.
The resin production is the real star. GG#4 Auto throws out enough trichomes to make her an excellent candidate for concentrates and edibles. If you've been wanting to press your own rosin or make bubble hash, this is the strain to grow. The sticky, gluey texture of the fresh buds isn't just a name — it's a genuine handling experience. Keep isopropyl alcohol nearby during trim.
GG#4 Auto Compared to Other Autoflowering Strains
| Feature | GG#4 Auto (BSF Seeds) | Typical Fast Auto | Typical High-Yield Auto |
|---|---|---|---|
| Seed to Harvest | 65 days | 55–60 days | 70–80 days |
| Indoor Yield | 500g/m² | 300–400g/m² | 500–600g/m² |
| Resin Production | Exceptional | Moderate | Good |
| Training Tolerance | Good (topping, SOG) | Low | Moderate |
| Flavour Complexity | Diesel, earth, pine | Often one-note | Varies |
GG#4 Auto sits in a sweet spot: faster than most heavy-yielding autos, more productive than most fast-finishing ones. The resin output puts her in a different league entirely for extract-focused growers.
Growing GG#4 Auto indoors? Pair her with a proper grow tent and carbon filter setup — the diesel terps will announce themselves to your entire building by week 5. A magnifying loupe is also worth grabbing so you can check trichome colour and harvest at peak ripeness rather than guessing.
How to Grow GG#4 Auto Seeds
- Germinate seeds using the paper towel method or directly in a small pot of moist, airy soil. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final container early — 11–15 litre pots work well. Autos don't like root disturbance, so minimise transplanting. Some growers start directly in the final pot.
- Provide 18–20 hours of light per day from seedling stage through harvest. GG#4 Auto doesn't need a light cycle change to trigger flowering.
- Begin light feeding with a balanced vegetative nutrient around week 2. Switch to bloom nutrients when you see the first pistils, typically around day 21–28.
- If topping, do it once at the 3rd or 4th node while the plant is growing vigorously — ideally before day 21. After that, stick to low-stress training only.
- Monitor humidity closely from week 5 onwards. Keep RH below 50% to protect those resin-heavy buds from mould.
- Harvest around day 65 when trichomes are mostly milky with a few turning amber. The diesel and pine aromas will be at full intensity — trust your nose and your loupe.
- Dry slowly in a dark room at 18–20°C and 55–60% RH for 7–10 days, then cure in glass jars for at least 2 weeks. The flavour improves dramatically with proper curing.
Frequently Asked Questions
How long does GG#4 Auto take from seed to harvest?
About 65 days from germination to chop. That's roughly 9 weeks total — significantly faster than photoperiod versions of GG#4, which need a separate veg period plus 8–9 weeks of flowering.
What yield can I expect from GG#4 Auto indoors?
BSF Seeds lists up to 500g/m² indoors under optimal conditions. In a well-dialled 18/6 light setup with proper feeding, 400–500g/m² is realistic. Outdoors, expect around 300g per plant.
Is GG#4 Auto suitable for beginner growers?
Yes — she's low-maintenance and doesn't require light schedule changes. New growers can get solid results by simply providing consistent light, water, and nutrients. Just avoid heavy training techniques until you're comfortable reading the plant's response.
Can I use GG#4 Auto for making concentrates?
Absolutely — this is one of the best auto strains for extracts. The resin production is exceptional, making her well suited to rosin pressing, bubble hash, and edible production. The diesel and pine terpenes carry through into concentrates beautifully.
What flavours does GG#4 Auto produce?
Expect sharp diesel on the front, followed by damp earth and sweet, woody pine. The terpene profile is dominated by myrcene, caryophyllene, and limonene — it's a complex, layered flavour that improves with a proper 2-week cure.
Does GG#4 Auto respond well to topping?
BSF Seeds confirms she takes well to topping and SOG. Top once at the 3rd or 4th node before day 21 while the plant is growing strongly. After that point, stick to low-stress training — there isn't enough veg time left for the plant to recover from high-stress techniques.
What's the difference between GG#4 Auto and photoperiod GG#4?
The auto version finishes in 65 days total regardless of light schedule, stays shorter, and requires no light cycle change. The trade-off is slightly less control over plant size and a narrower training window. Resin production and flavour are very close to the photoperiod original.
