Gorilla Glue #4 Auto: The Sticky-Fingered Champion
Looking to get your hands on a bona fide legend? Gorilla Glue #4 Auto is the same award-winning heavyweight, but with a new engine. This fast-growing, resin-soaked autoflower delivers the same powerful combo of euphoria and deep relaxation as its photoperiod big brother. If you’re looking to buy autoflowering Gorilla Glue #4 seeds in Australia, you’re investing in a ridiculously resilient, ridiculously frosty powerhouse that sticks to everything it touches.
Quick Stats
Hybrid autoflower with ~20–25% THC, running a 9–10 week seed-to-harvest sprint. Indoors expect roughly 400–500 g/m²; outdoors up to 100–250 g/plant in warm, sunny spots. In Australia, outdoor harvest typically lands late March–April. Matty’s tip: start her in the final pot and go easy on feed—autos usually hate heavy EC.
The Legend
Gorilla Glue #4, or GG4, is a three-way genetic masterpiece: Chem’s Sister × Sour Dubb × Chocolate Diesel. She shot to fame with big wins at the 2014 Cannabis Cups (Michigan & Los Angeles) and the High Times Jamaican World Cup in 2015.
Funny fact: the “Glue” name stuck after growers found the resin so thick it literally gummed up fingers and trimming shears. If you’ve ever glued your fingers together, you’ll know the pain.
Flavour & Aroma
Big, loud, and impossible to ignore—GG4 arrives with boots on.
- On the nose: rich earth and fresh pine with a sharp diesel edge.
- On the tongue: diesel-forward and earthy with nutty/chocolate flickers; a lingering, punchy finish.
Matty’s Take: “She smells like a mechanic’s bay parked in a pine forest—bit of cocoa peeking through. Proper in-your-face funk.”
Effects & What to Expect
GG4 is a hybrid for a reason—she hits both head and body.
First wave: a bright, cerebral lift and creative spark.
Then the glue sets: deep, heavy relaxation that makes couches feel magnetic. Perfect for evenings when the to-do list is done and the snacks are lined up.
How I Grow It (Matty’s Way)
New to autos or just want a fast, explosive run? This one’s a champ. Keep the basics tight and she’ll reward you with dense, sugar-dusted colas.
Matty’s Feeding & pH Know-How: “Start her in the final pot, no mucking about. pH 6.0–7.0 in soil; 5.5–6.5 in coco/hydro. Gentle, steady feed—autos don’t like heavy hands.”
Maximising Yield: Short, bushy structure loves light, warmth, and airflow. Gentle LST opens the canopy and evens the tops. With just 9–10 weeks from seed, she’s perfect for quick turnarounds. In Australia, outdoor finish is usually late March–April.
Grow Log: Inside the Tent
Matty’s Warning: “She frosts up like a bakery freezer door—dense buds mean airflow is non-negotiable. A decent fan is cheaper than losing a cola to botrytis.”
| Phase/Week | Key Action | Matty’s Tip |
|---|---|---|
| Veg Week 3 | Explosive, bushy growth with tight node stacking. | Start gentle LST now to open the canopy early. |
| Flower Week 4 | Stretch done; bud sites stacking; resin appearing. | She’s hungry—keep feeds steady but don’t overdo EC. |
| Flower Week 7 | Colas get heavy; aroma cranks up. | Carbon filter will work overtime—check airflow paths. |
| Harvest Week | Rock-solid, sugar-dusted colas. | Plain water for 7–10 days before chop for a clean finish. |
Matty’s Advanced Notes (For the Nerds in the Room)
- EC in bloom (hydro/coco): sweet spot ~1.5–2.0 EC; many autos are happiest ≤1.8 EC. Ramp from ~1.2–1.3 EC early flower to peak—watch leaf tips.
- Reservoir temps: keep 18–20 °C with strong dissolved oxygen.
- Environment targets: flower VPD roughly 1.2–1.4 kPa; RH ~45–55% early bloom, easing to 40–45% late.
- pH: soil 6.0–7.0; coco/hydro 5.5–6.5 (aim ~5.8–6.0 in hydro).
- Airflow: dense buds need cross-breeze through (not just over) the canopy; rotate fans as plants fill out.
Mythbusting
Myth: “Autos can’t handle training.”
Truth (Matty): Gentle, early LST is ideal—more light on more sites = better yield.
Myth: “Autos need massive EC to stack weight.”
Truth (Matty): Too hot backfires. Most GG4 autos shine at ≤1.8 EC with clean, stable feeds.
Myth: “Auto highs are short and weak.”
Truth (Matty): GG4 Auto hits hard—bright first act, heavy finish, plenty of stay-time.
Who It’s For?
Perfect If You:
- Want fast, reliable runs without flipping light schedules.
- Prefer dense, resin-caked buds and easy trimming.
- Like an evening high that lifts first, then settles you right down.
Maybe Not For You If You:
- Need ultra-zippy daytime strains only.
- Prefer long veg, high-training photoperiod projects.
Final Verdict
- Speed: seed to jar in ~9–10 weeks.
- Pedigree: celebrated GG4 lineage with proven cup credentials.
- Return: chunky yields and extreme resin with minimal fuss.
- Experience: euphoric lift that glides into premium couch-time.
Matty’s Final Word: “Don’t fight the glue—line up the snacks and enjoy the stuck.”
