Get Royal Cookies Automatic seeds and grow a powerful, easy-care autoflowering version of the legendary Girl Scout Cookies — with heavy yields, 18% THC, and a sweet, earthy flavor in just 50–60 days.

Still stuck with slow-growing photoperiods that need light cycle changes and endless babysitting? You’re not alone. Most growers waste weeks waiting for flowering to start, only to end up with weak yields and inconsistent quality. And if you’re short on space or time, traditional strains just don’t cut it.

That frustration only grows when you realize you’re missing out — your plants take too long, demand too much, and still don’t deliver that rich, cookie-like flavor you’re chasing. Every day you wait is another day without harvest, another chance for mold, pests, or light leaks to ruin your run.

But what if you could grow top-shelf GSC-quality buds in under ten weeks, with zero light management and minimal effort? Royal Cookies Automatic changes the game. Thanks to its autoflowering genetics, it starts flowering on its own, delivering up to 450g/m² indoors and 180g per plant outdoors. With tight, resin-coated buds, a THC punch of up to 18%, and that iconic sweet, earthy aroma, this strain brings the flavor and power you want — fast. It’s forgiving, mold-resistant, and perfect for SOG setups, so even beginners score like pros.

How to grow Royal Cookies Automatic seeds

Grow fast, grow easy — this autoflower thrives with simple care and smart inputs.

Quick overview: autoflowering · Royal Queen Seeds · 50–60 day cycle · low difficulty · ideal for indoor, outdoor, and balcony grows.

Safe start: germinate in a moist paper towel at 22–25 °C. Transplant carefully when the taproot is ~1 cm long. For a stronger start, Clonex Rooting Hormone Gel boosts root development and reduces shock.

Stable seedling: keep humidity at 60–70% and use gentle light. Water lightly and ensure good drainage. A well-aerated soil mix prevents root rot and supports early growth.

Directed growth: provide 18–20 hours of light daily. Use a final pot of 18–27 L early to avoid transplant stress. FloraDuo Grow delivers balanced nutrition for steady, healthy development without overfeeding.

Efficient flowering: maintain RH at 40–50% and increase airflow to prevent mold. Support branches if needed. HESI Hydro Bloom enhances resin production and bud density during peak flowering.

Harvest and refinement: harvest when trichomes turn milky to amber for a balanced effect. Flush 7–10 days before harvest. Dry at 18–22 °C and 50–60% RH, then cure for 2–4 weeks to maximize flavor.

Frequently Asked Questions

Personal Experience of Pevgrow’s CEO (Alan)

Let me tell you, Royal Cookies Automatic was a game-changer for my balcony grow last summer. I was tired of waiting 14 weeks for photoperiods to finish, so I gave these a shot — and damn, they delivered. Planted three in 20L pots, used a simple soil mix with some perlite, and ran 18/6 lighting. They popped fast, grew sturdy, and started flowering like clockwork. No stress, no light leaks, no drama. By week ten, I had dense, trichome-covered colas that smelled like fresh-baked cookies. I cured them for three weeks, and the flavor? Unreal — sweet, earthy, with that minty kick. The high hit hard and smooth, perfect for chilling after work. Even my neighbor, who knows nothing about growing, asked what I was smoking. If you want GSC power without the wait, this is your seed. Just don’t overwater — I lost one plant to root rot early on. Learn from my mistake: go easy on the water, and you’ll be golden.
