GG4

What Are GG4 Seeds?

GG4 seeds produce one of the most resin-drenched, trichome-heavy sativa-leaning hybrids you can grow at home. Bred from a triple cross of Chem Sis, Sour Dubb, and Chocolate Diesel, GG4 — also known as Gorilla Glue #4 — packs 27% THC alongside 0.8% CBD, delivering an energetic, uplifting high with a sharp pine-and-diesel terpene edge. These feminized seeds guarantee every plant flowers, so there's no wasted weeks identifying and culling males. The strain stays compact at 90–120 cm indoors, finishes in 8–10 weeks under a standard 12/12 light cycle, and throws dense, sticky colas that are built for solventless extraction. We've stocked GG4 seeds in our Amsterdam shop since 1999 — that's over 25 years on our shelves — and they outsell most newcomers every single season. If you want a reliable, forgiving grow with serious potency and extract potential, GG4 feminized seeds are the obvious starting point.

Why You Need This

Here's the problem with most seed purchases: you pop a pack, spend three weeks in veg, and then discover half your plants are male. You cull them, your canopy has gaps, and your yield takes a hit. Or worse — you pick a trendy strain that stretches to the ceiling, demands precise nutrient ratios, and still gives you wispy, underwhelming buds. We've seen it happen from behind our counter in Amsterdam more times than we can count.

GG4 feminized seeds eliminate most of that frustration. Every seed produces a flowering female plant, so nothing gets wasted. The genetics are forgiving — this strain doesn't throw tantrums over minor pH swings or imperfect climate control. It stays between 90–120 cm indoors, which means it fits comfortably in a standard tent without aggressive topping or constant height management. And the resin output is genuinely exceptional. During trimming, the trichome layer literally glues your fingers together. Scissors stick shut. It's the strain that earned its name honestly.

We first put Gorilla Glue #4 seeds on our Amsterdam shelves in 1999. Since then, we've watched hundreds of trendy genetics cycle in and out — but GG4 never left. It's still here because it works. First-timers succeed with it because it stays compact and doesn't demand a perfect environment. Experienced growers come back to it because 27% THC and that heavy trichome coverage make it one of the most efficient strains for rosin pressing and solventless extraction. If you've been burned by unreliable genetics before, GG4 seeds are the reset.

How to Grow GG4 Seeds: Step by Step

1. Germinate: Soak your GG4 seeds in water for 12–24 hours, then transfer to damp paper towels in a warm, dark spot. Taproots typically appear within 48 hours.
2. Seedling stage: Plant the sprouted seed 1 cm deep in a small pot with light, airy soil. Keep humidity around 65–70% and use a gentle 18/6 light schedule.
3. Vegetative growth: Allow 2–3 weeks of veg under 18/6 lighting. GG4 stays compact, so this is the time to start LST or set up your trellis net for an even canopy.
4. Flip to flower: Switch to a 12/12 light cycle to trigger flowering. Expect 8–10 weeks from flip to harvest. Watch humidity closely — drop it below 50% by mid-flower.
5. Late-flower airflow: Those dense, resin-soaked colas trap moisture. Run oscillating fans and keep relative humidity at 40–45% in the final weeks to prevent mould in the centre of the buds.
6. Flush and harvest: Flush with plain water for the last 7–10 days. Harvest when trichomes shift from clear to milky-amber. Dry slowly in a dark room at 18–20°C for the best terpene preservation.

GG4 Strain Effects and Flavour Profile

GG4 seeds grow into a mostly sativa-leaning hybrid that hits with an immediate cerebral rush — focused, uplifting, and energetic without the jittery edge some pure sativas bring. The 27% THC lands fast, lifting mood and sharpening creativity before a gentle body warmth settles in. It's a daytime strain at heart, though the 0.8% CBD rounds the experience just enough to keep tension at bay.

The terpene profile is unmistakable. Crack open a cured jar and you get a wall of sharp pine and raw diesel, inherited directly from the Chem Sis and Sour Dubb parentage. Underneath that fuel-forward punch sits a sweet fruit finish — a subtle, almost candied note courtesy of the Chocolate Diesel genetics. When you smoke or vape it, the pine leads on the inhale and the sweetness lingers on the exhale. It's loud, complex, and absolutely drenched in resin. During harvest, the trichome coverage is so dense your trimming scissors will seize up within minutes. That sticky, glue-like resin is exactly what makes GG4 one of the top choices for pressing rosin — the return rates are consistently impressive.

Compared to GSC (Girl Scout Cookies), GG4 finishes faster, pushes higher THC, and leans energetic rather than sedative. GSC takes longer in flower, drops harder into couch-lock territory, and requires more precise feeding schedules. If you want a quicker turnaround with a more uplifting effect, GG4 seeds are the stronger pick.

How to Grow GG4 Seeds Indoors

GG4 seeds thrive indoors under a standard 12/12 light cycle during flower, with 8–10 weeks from flip to chop. Start your plants under 18/6 lighting for 2–3 weeks of vegetative growth — this strain stays between 90–120 cm, so you won't need excessive vertical space. A 120x120 cm tent with 5 plants is the sweet spot for canopy coverage.

Training is where GG4 really responds well. Low-stress training (LST) opens up the lower bud sites and keeps the canopy flat, while a trellis net distributes those heavy colas evenly across the tent. Top once during early veg to encourage lateral branching, then weave shoots through the net as they stretch in the first two weeks of flower.

Now, the honest bit: GG4's dense, resin-soaked buds are a double-edged sword. That thick trichome layer and tight bud structure trap humidity inside the colas. If you don't manage airflow in late flower, you'll risk mould forming in the centre of the buds — and you won't see it until you cut them open. Keep relative humidity below 45% from week six onward. Run oscillating fans at canopy level and make sure your exhaust is pulling air consistently. A carbon filter handles the intense diesel smell while maintaining airflow. Get the environment right and GG4 rewards you with some of the stickiest, most extract-worthy buds you'll ever trim.
