GG#4 Auto

GG#4 Auto by FastBuds — Award-Winning Resin Monster, Now on Autopilot

GG#4 Auto is an autoflowering cannabis seed from FastBuds that delivers the legendary resin production and couch-melting potency of the original Gorilla Glue #4 — without the fuss of photoperiod light schedules. Created from the genetics of Joesy Whales and Lone Watie's multi-cup-winning hybrid, this autoflower finishes seed to harvest in just 8–9 weeks and coats everything it touches in a thick layer of sticky trichomes. If you want a no-nonsense grow with genuinely impressive output, this is where you start.

Why GG#4 Auto Seeds Deserve a Spot in Your Grow Room

The original GG#4 won Best Hybrid at both the 2014 SoCal Cup and the 2014 Michigan Cup — back-to-back, no contest. That kind of pedigree doesn't happen by accident. The strain earned its nickname because the resin literally glues your scissors shut during trimming. We've seen growers go through three pairs of trimming shears on a single plant. FastBuds took those genetics and crossed them into a ruderalis-backed autoflower that keeps the ridiculous trichome coverage and adds the convenience of a fixed life cycle.

What you get is a plant that doesn't care about your light schedule. Set it to 18/6 or 20/4 from seed and she'll do her thing regardless. No flipping to 12/12, no worrying about light leaks disrupting the flowering cycle. For growers in smaller spaces — or anyone who just wants to keep things simple — that's a genuine advantage over the photoperiod version.

The honest limitation? Autoflowers generally produce slightly less weight per plant than their photoperiod counterparts. You're not going to pull a kilo off a single GG#4 Auto. But the quality-to-effort ratio is outstanding. The buds are dense, absolutely caked in resin, and the terpene profile — pine, lemon, diesel fuel — fills the room from week five onwards. If you've ever grown a photoperiod GG#4 and loved the end product but hated babysitting the light timer, this is the answer.

GG#4 Auto Growing Specs and Yield Performance

FastBuds rates GG#4 Auto at 400–600g/m² indoors under a 600W light, which is seriously competitive for an autoflower. Outdoors, expect up to 300g per plant under optimal conditions. The full cycle from germination to chop runs 8–9 weeks — roughly two months from cracking the seed to drying your harvest.

GG#4 Auto Aroma and Flavour — Pine, Lemon, and Diesel

Crack open a cured bud and the first thing that hits you is sharp pine, almost like snapping a fresh spruce branch. Underneath that sits a bright lemon note that lifts the whole profile, followed by a deep, unmistakable fuel funk that lingers on your fingers. It's not subtle. If you're growing without a carbon filter, your neighbours will know about it by mid-flower.

The smoke carries those same notes through — the pine and lemon lead on the inhale, and the diesel comes through on the exhale with a slightly earthy, almost chocolate undertone. It's a complex, layered flavour that keeps you coming back. Compared to something like a Zkittlez Auto, which is all fruit and candy, GG#4 Auto sits firmly on the dank, resinous side of the spectrum. If you like your weed to smell like weed, this is your strain.

How to Grow GG#4 Auto Seeds

1. Germinate your GG#4 Auto seeds using the paper towel method or directly in a small pot of moist, airy soil. Taproots typically appear within 24–72 hours.
2. Plant the germinated seed 1–2cm deep in its final container. Autoflowers don't love transplanting — start in the pot you plan to finish in. A 15–20 litre fabric pot works well.
3. Set your light schedule to 18 hours on, 6 hours off from day one. Some growers push to 20/4 for extra growth; either works. GG#4 Auto doesn't need a light flip to start flowering.
4. Keep humidity around 65–70% during the seedling stage, dropping to 40–50% once flowers form. Good airflow prevents mould, especially given how dense these buds get.
5. Feed lightly for the first two weeks, then ramp up nutrients as she enters pre-flower (usually around week 3–4). She's not a heavy feeder early on, but she'll drink once the stretch kicks in.
6. Watch for the explosive resin production from around week 5. Trichomes will coat the sugar leaves, calyxes, and even parts of the stems. Use a jeweller's loupe to check trichome colour — harvest when most are milky with a few turning amber.
7. 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 two weeks. The pine and lemon terps develop beautifully during a proper cure.

GG#4 Auto vs Photoperiod GG#4 — What's the Trade-Off?

The photoperiod GG#4 gives you more control. You can veg her longer, train her into a wide canopy, and potentially pull bigger harvests. But she needs a strict 12/12 light cycle to flower, and any light leaks can cause stress or hermaphrodite issues. Total grow time runs 14–18 weeks depending on how long you veg.

GG#4 Auto trades some of that control for speed and simplicity. Eight to nine weeks, done. No light schedule changes, no worrying about light pollution. The resin production is comparable — genuinely, we'd challenge anyone to tell the difference in a blind trichome comparison. Yield per plant is lower, but yield per year can actually be higher because you can fit more cycles into the same calendar.
