Triple G

Triple G Autoflower Cannabis Seeds by Royal Queen Seeds

Triple G Autoflower is an indica-dominant autoflowering cannabis seed from Royal Queen Seeds that delivers dense, resinous buds in just 10-12 weeks from seed. A cross between regular Triple G (Gorilla Glue #4 x Gelato 33) and Big Skunk Auto, this 80% indica hybrid packs 20% THC into a compact plant that rarely tops 120cm indoors. If you want heavy resin production without the fuss of photoperiod lighting schedules, this is the one.

Triple G Auto Genetics: Gorilla Glue Meets Gelato in an Autoflower

The name Triple G comes from the parent strain's lineage: Gorilla Glue #4 crossed with Gelato 33. That pairing alone is responsible for some of the stickiest, most aromatic flower in recent cannabis breeding history. Royal Queen Seeds then crossed regular Triple G with their Big Skunk Auto to lock in autoflowering traits and add a layer of Skunk vigour to the mix. The result is 80% indica genetics wrapped in a ruderalis-driven flowering engine that doesn't care what your light cycle looks like.

What you actually get from this genetic cocktail: tight internodal spacing, thick central stems, and buds that stack up like little fists along the branches. The Gorilla Glue side brings the resin — expect trichome coverage that extends well onto the sugar leaves. The Gelato influence shows up in the terpene profile, adding sweetness and depth to what would otherwise be a straight diesel-and-earth affair. And the Big Skunk Auto backbone keeps the whole thing moving fast, pushing from seedling to sexed plant in roughly 5 weeks.

Growing Triple G Autoflower Seeds: What to Expect

Triple G Autoflower is a short, stocky grower that stays manageable even in tight spaces. Indoor plants typically reach 60-120cm with close internodes, thick foliage, and strong central stems that don't need much support. Outdoors, plants stretch a bit taller — up to around 140cm — depending on your climate and sun exposure.

Once past the seedling stage, these plants grow vigorously, especially under long light hours. We'd run 20/4 indoors for the best balance of growth and rest. After roughly 5 weeks of vegetative growth, Triple G Auto plants sex themselves and flip into flower without any change to your lighting schedule. That's the beauty of autos — no timer gymnastics, no light leak paranoia.

The flowering phase is where this strain earns its keep. Buds fatten up quickly, stacking dense calyxes coated in resin. Indoor yields reach up to 500g/m2 in optimal conditions — that's strong for an auto. Outdoor plants produce 90-120g per plant, which is respectable for a plant that barely reaches waist height. Total time from seed to chop: 10-12 weeks. Outdoor plants may run slightly longer depending on temperatures and day length.

Aroma and Flavour Profile of Triple G Auto

This is where Triple G Autoflower really stands out. Crack open a cured bud and the first thing that hits you is earth — deep, damp, almost forest-floor rich. Then the sweetness rolls in: candy-like, with a distinct chocolate undertone that's more dark cocoa than milk bar. Behind all of that sits the Skunk, unmistakable and pungent, adding a sharpness that rounds out the whole profile.

During the later weeks of flowering, the plants themselves start filling the room with a fresh, earthy aroma laced with spice. If you're growing without a carbon filter, your neighbours will know about it. Once you light up the dried flower, the pungency goes up another level — thick, resinous smoke that coats the palate with that chocolate-earth-Skunk combination. The terpene mix here is complex enough to keep things interesting across multiple sessions.

One honest note: the Skunk side of this strain is not subtle. If discretion matters to you during the grow, invest in proper extraction and carbon filtration. The buds themselves store well in airtight glass jars, but even a quick open fills whatever room you're in.

Why Triple G Autoflower Is Worth Growing

We've carried a lot of autoflower seeds over the years, and the gap between autos and photoperiods has closed dramatically. Triple G Auto is a good example of where modern auto breeding has landed: 20% THC, 500g/m2 potential, and a terpene profile that doesn't take a back seat to its photoperiod parent. Five years ago, you'd have laughed at those numbers from an auto. Now it's just Tuesday.

The real selling point is the timeline. Ten to twelve weeks from dropping the seed into soil to trimming finished buds. No veg-to-flower transition to manage, no worrying about light pollution triggering early bloom. You plant it, feed it, and it does its thing on autopilot. For growers running perpetual harvests, that predictability is gold — you can stagger plantings and pull a fresh crop every few weeks from the same tent.

Compared to something like Royal Queen Seeds' Royal Gorilla (the photoperiod version), Triple G Auto trades a bit of raw potency and yield ceiling for speed and simplicity. Royal Gorilla can push past 25% THC and produce monster yields, but it needs 8-9 weeks of flower after a full veg cycle, plus precise 12/12 lighting. Triple G Auto gives you 80% of the result in half the total time. For most home growers, that's the better deal.

The one thing to watch: because of the dense bud structure (thanks to that indica dominance and tight internodal spacing), airflow matters. In humid climates or poorly ventilated spaces, those thick colas can trap moisture. A small oscillating fan pointed at the canopy during late flower goes a long way. Defoliate the lower canopy in week 3-4 of flower to let air circulate around the base of the plant.

How to Grow Triple G Autoflower Seeds

1. Germinate your seeds using the paper towel method or by placing them directly into moist soil or a jiffy pellet. Keep temperatures around 22-25°C and maintain humidity at 70-80% during germination. Taproots typically emerge within 24-72 hours.
2. Transplant seedlings into their final container as soon as the first true leaves appear. Autos don't like being transplanted mid-grow — root disturbance slows them down and you can't recover lost time with a longer veg phase. Use 11-15 litre pots for a good balance of root space and manageable watering.
3. Set your indoor lights to a 20/4 schedule (20 hours on, 4 hours off) from seedling through to harvest. Triple G Auto responds well to extended light hours. Use a quality LED or 400-600W HPS for best results.
4. Feed lightly during the first 2-3 weeks — seedlings don't need much. Once vegetative growth kicks in (around week 2-3), introduce a mild grow-phase nutrient. Switch to bloom nutrients when you see the first pistils forming, typically around week 5.
5. Monitor humidity as buds develop. Drop relative humidity to 40-50% during late flower to protect those dense, resinous colas from mould. Defoliate lower fan leaves in weeks 3-4 of flower to improve airflow through the canopy.
6. Harvest when 70-80% of trichomes have turned milky white with a few amber heads. This typically falls between weeks 10-12 from seed. 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 2 weeks before sampling.
