Triple G Auto – Royal Queen Seeds | High-THC Autoflower with Gelato & Gorilla Genetics · Fast 10–12 Week Harvest

Triple G Auto by Royal Queen Seeds is a high-THC autoflower that delivers heavy yields, intense flavor, and a rapid 10–12 week grow cycle — all wrapped in elite Gelato and Royal Gorilla genetics.

Worried your auto won’t pack a punch?

Let’s be real: most autoflowers are mild, forgettable, and barely scratch the surface of what a real high should feel like. You invest weeks of care, only to end up with fluffy, low-THC buds that don’t deliver.

Weak autos waste your time and space

They stretch too much, yield next to nothing, or collapse under their own weight. And when harvest finally comes, the flavor’s flat, the high is underwhelming, and you’re left wondering if it was even worth it. You don’t want a plant that just survives — you want one that dominates.

Triple G Auto hits like a photoperiod — but grows like an auto

This isn’t your average autoflower. With up to 20% THC, Triple G Auto delivers a fast, euphoric body high that melts stress and locks you into deep relaxation. Thanks to its Royal Gorilla × Green Gelato × Big Skunk Auto lineage, it grows fast, stays compact (0.60–1.20 m / 2–4 ft), and produces dense, frosty buds indoors or outdoors. Expect up to 500 g/m² (16–19 oz/m²) indoors or 75–140 g/plant (2.6–5 oz/plant) outdoors — all in just 10–12 weeks from seed to harvest.

What to expect the first few times

Triple G Auto kicks off with a strong start — no weak seedlings here. The first few days show rapid taproot development and sturdy cotyledons. By week 3, you’ll notice thick stems and wide internodal spacing, setting the stage for a bushy, well-branched plant. Don’t be surprised if it smells skunky by week 4 — that’s the Big Skunk Auto heritage announcing itself. Early flowering begins around week 5, and from there, resin production goes into overdrive. Stick with it, and you’ll be rewarded with chunky, trichome-coated colas that feel solid in your hand.

Common mistakes and how to avoid them

• Overpotting too early — stick to a 1L pot for the first two weeks, then move to 18–27 L final.
• Overwatering in early veg — let the top 2 cm (0.79 in) dry between waterings.
• Aggressive topping or FIM — avoid it; autos don’t recover well from pruning stress.
• Using photoperiod lighting cycles — keep 18–20 hours of light daily for the entire cycle.
• Ignoring humidity drops in flowering — maintain 40–50% RH to prevent mold in dense buds.

How to fine-tune your grow for maximum yield

1. Start in a 1L pot for the first 14 days to avoid waterlogged roots.
2. Move to a final pot of 18–27 L (5–7 gal) to support full root development.
3. Use a light, airy soil mix or coco with Alg-A-Mic BioBizz for microbial support.
4. Keep light at 18–20 h/day — no need to switch to 12/12.
5. Boost flowering with Super PK Aptus during peak bloom for denser buds.
6. Monitor trichomes — harvest when mostly milky with slight amber for balanced effects.
7. Flush 7–10 days before harvest to improve smoothness and flavor.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Triple G Auto last summer in my greenhouse, and damn — it hit different. I was skeptical at first. Most autos fizzle out by week 8, but this one kept building. I topped one plant out of curiosity — big mistake. It stalled for nearly a week. The untopped one? Exploded. By week 10, both were heavy with resin, but the clean one yielded 30% more. I ran 18/6 light, used a soil-coco mix, and added Super PK at week 6. The flavor was next level — sweet candy with a skunky punch. One hit and you’re locked in. If you want power, speed, and flavor in one auto, this is it.
