GG#4 Auto

GG#4 Auto Cannabis Seeds by Auto Seeds

GG#4 Auto is a fully stabilised autoflowering cannabis seed that packs the legendary potency of the original Gorilla Glue #4 into a compact, fast-finishing plant anyone can grow. Auto Seeds crossed a selected phenotype of the original GG#4 with their Auto #1, producing an autoflower with THC levels between 23% and 27% — territory that most photoperiod strains struggle to reach. From seed to harvest in 70–75 days, with yields up to 600g/m² indoors, this is the strain that makes autoflowers hard to dismiss.

Why GG#4 Auto Cannabis Seeds Deserve the Hype

The original Gorilla Glue #4 built its reputation on the US west coast with some phenotypes testing above 30% THC — numbers that turned heads across the entire cannabis world. The problem was always accessibility: she was a photoperiod-only clone, fussy about light schedules, and not exactly beginner-friendly. Auto Seeds solved that. Their GG#4 Auto brings the same resin-drenched, glue-your-scissors-shut genetics into an autoflowering format that finishes in 70–75 days regardless of your light cycle.

We'd pick this over most photoperiod indicas if speed and simplicity matter to you. A 65-day flowering window means you can run multiple cycles per year, even outdoors in northern Europe. And because she stays between 65cm and 100cm, you're not fighting height issues in a 120cm tent. We've seen growers squeeze four of these into an 80x80 and pull genuinely impressive harvests — the kind of results that make you wonder why you ever bothered with photoperiods at all.

The honest limitation? Autoflowers don't let you extend veg time to recover from early mistakes. If you stunt her in the first two weeks with overwatering or a cold snap, you can't just flip to 12/12 later and let her catch up. She's on a genetic timer. Treat those first 10 days like they matter — because they do.

Growing GG#4 Auto: What to Expect

GG#4 Auto cannabis seeds are genuinely forgiving. Auto Seeds stabilised this strain to handle fluctuations in nutrients, pH, moisture, and temperature — the kind of variables that would stress a more temperamental cultivar into foxtailing or hermaphroditism. That tolerance makes her the best autoflowering strain for first-time growers who want results that don't look like a first-time grow.

She pushes through veg with solid vigour and transitions into flower automatically around day 10–14. By week three, you'll notice the stretch slowing and bud sites stacking. By week five, the resin production kicks into overdrive — this is where GG#4 earns the "Gorilla Glue" name. Trichomes coat everything: fan leaves, sugar leaves, even stems. If you've never had to clean your trimming scissors with rubbing alcohol every ten minutes, you're about to learn.

1. Germinate seeds using the paper towel method or directly in a small pot of lightly moistened seedling soil. Keep temperatures around 22–25°C.
2. Transplant into your final container (7–11 litres works well) once the first true leaves appear. Autoflowers don't love root disturbance, so avoid repotting more than once.
3. Run 18–20 hours of light throughout the entire cycle. GG#4 Auto doesn't need a light schedule change to flower — she'll do it herself around day 10–14.
4. Start feeding at quarter strength once the third node appears. Increase gradually. This strain tolerates nutrient variation, but she's not invincible — ease into bloom nutrients when you see pistils forming.
5. Monitor humidity: keep it below 50% during flowering to protect those dense, resin-heavy buds from mould. Good airflow is non-negotiable once the canopy fills in.
6. Flush with plain water for the final 7–10 days before harvest. Trichomes should be mostly milky with a few turning amber — that's your window for peak potency.
7. Dry slowly in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in glass jars for at least two weeks. The terpene profile develops significantly during curing.

Flavour, Aroma and Resin: GG#4 Auto Terpene Profile

GG#4 Auto delivers a robust, earthy flavour with unmistakable layers of pine, diesel, chocolate, and coffee. It's not a subtle smoke — the diesel hits first, then the chocolate and coffee notes settle in on the exhale. The aroma during the final weeks of flowering is equally bold: sharp pine resin and fuel that a carbon filter can only partially tame. If discretion matters, plan accordingly.

The resin production is, frankly, absurd. The original GG#4 parentage — with some phenotypes exceeding 30% THC — passes that sticky, trichome-heavy character straight through to this autoflowering version. According to research published in BMC Complementary Medicine and Therapies, terpenes such as beta-myrcene (commonly found in cannabis) demonstrate anti-inflammatory properties in laboratory settings (PMC11085560). The terpene and cannabinoid combination in GG#4 Auto is part of what researchers call the entourage effect — a phenomenon where terpenes work in combination with cannabinoids, as described in a 2018 study published in the Journal of Cannabis Research (PMC5968020).

For hash makers and extract enthusiasts, this strain is a dream. The sheer volume of trichome heads means higher returns on dry sift, bubble hash, or rosin pressing compared to most autoflowers — and quite a few photoperiod strains, too.

THC Potency and What That Means for You

With THC levels ranging from 23% to 27%, GG#4 Auto sits firmly in the heavy-hitter category. For context, the average dispensary strain in mature markets hovers around 18–22%. This strain exceeds that ceiling comfortably, and its indica-dominant genetics deliver a physical, full-body effect that builds in intensity. The original GG#4 has been documented at over 30% THC in certain phenotypes — Auto Seeds' version inherits that potency lineage.

According to a review published in the Journal of the International Neuropsychological Society, higher THC concentrations were correlated with increased intensity of cognitive and mood effects (PMC6455965). This is a strain where starting slow and respecting the potency pays off. A single joint of properly grown and cured GG#4 Auto is not a casual weeknight smoke — it's a commitment. Indica lovers will appreciate the depth; newcomers should approach with caution and small amounts.
