Green Gelato Auto – Royal Queen Seeds | 24% THC Indica-Dominant Hybrid for Fast, High-Yielding Grows

Green Gelato Auto by Royal Queen Seeds is an insanely potent, fast-flowering autoflower that delivers up to 24% THC and yields of 450g/m² in just 70 days — no green thumb required.

Are you tired of weak autoflowers that barely get you buzzed?

Most autoflowering strains are known for mild potency and modest harvests — perfect for beginners, but forgettable for real connoisseurs. You want something that hits hard, tastes incredible, and doesn’t demand your full attention.

What if your auto could rival a top-shelf photoperiod?

Imagine waiting weeks for a mediocre yield, only to find weak flavor and a forgettable high. Or worse — your plant stretches out of control, smells up the neighborhood, or crashes during flowering. That’s the auto experience most growers know. You end up frustrated, underwhelmed, and questioning if it was worth the time.

Green Gelato Auto delivers photoperiod power in an autoflower package

Thanks to elite genetics from Thin Mint Cookies and Sunset Sherbet, this strain breaks the mold. With 24% THC, dense trichome-covered buds, and a rich dessert-like flavor, it’s built to impress. It finishes in 9–10 weeks from seed, stays compact at 0.80–1.20 m (2.62–3.94 ft), and produces up to 450g/m² indoors or 100g (3.53 oz) per plant outdoors. No training needed — just plant, feed, and watch it shine.

How Green Gelato Auto maximizes yield and flavor in record time

This autoflower doesn’t waste a second. From day one, it focuses energy on vertical growth and bud production, not foliage. Its short life cycle means you can run multiple harvests per year, especially under continuous 18–20h lighting. Indoors, it fills a 27L pot with a single main cola and strong lateral branching. Outdoors, it resists mold and pests, thriving in Mediterranean or temperate climates. The result? A bucket of frosty, aromatic buds in under 10 weeks.

Simple steps to grow Green Gelato Auto like a pro

1. Start with a 3–5L pot and move to 18–27L once roots peek out — this prevents stress and boosts yield.
2. Use a well-draining soil or coco mix; keep pH at 6.0–6.5 (soil) or 5.8–6.2 (coco).
3. Provide 18–20 hours of light daily; maintain temps at 22–26°C in veg and 20–25°C in flower.
4. Water when the top inch feels dry; avoid overfeeding — autos hate nutrient burn.
5. Support tall colas with stakes if needed, especially outdoors in windy areas.
6. Harvest when trichomes turn milky to amber for a balanced, long-lasting high.

Tips to get the most out of your Green Gelato Auto harvest

For maximum resin production, use a bloom booster like Top Bloom during peak flowering. Pair it with Orca Liquid Mycorrhizae at transplant to supercharge root development and nutrient uptake. Keep humidity below 50% in late flower to prevent mold, and flush with plain water 7–10 days before harvest for a smoother smoke.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Green Gelato Auto last summer in my 1.2m² tent with a 600W LED and 27L pots. Planted three seeds, all germinated, and two turned into monsters — one hit 115 cm (3.77 ft) with a main cola that needed staking. I used a simple soil mix with Granulated Bat Guano at the base and fed lightly with Top Crop. No topping, no LST — just let them fly. Harvested at 72 days with milky-amber trichomes. Dried slow, cured 3 weeks. The buzz? Clear, uplifting, then deeply relaxing — perfect for evening creativity or chilling with friends. The flavor is unreal: sweet vanilla with a citrus kick. If you want a no-fuss auto that smokes like a $30/8th, this is it.
