Auto Do-Si-Dos Cookies by 00 Seeds – 22% THC Indica Hybrid – High-Yielding Autoflower

Auto Do-Si-Dos Cookies by 00 Seeds is a high-THC autoflowering powerhouse that delivers top-shelf quality with beginner-friendly growing, giving you dense, resin-coated buds in under 90 days.

Overwhelmed by complicated grows and inconsistent results?

Let’s be real — not everyone has time for a 5-month grow cycle, delicate photoperiods, or plants that barely survive nutrient changes. You want something that just works, without the stress.

Why do so many grows end up disappointing?

Most autoflowers promise big yields but deliver weak flavors, spindly structure, or mold-prone buds. Others need constant tweaking — pH checks, aggressive training, or perfect climate control. And when you finally harvest? The high’s underwhelming, the taste is flat, and you’re left wondering if it was worth it.

Auto Do-Si-Dos Cookies is your no-fuss, high-reward solution

Bred from legendary Girl Scout Cookies and Do-Si-Dos genetics, this autoflower combines fast flowering with massive yields and a knockout flavor profile. It grows strong and bushy, resists common stressors, and finishes in just 80–90 days — all with minimal intervention. You get sticky, aromatic buds that deliver a deeply relaxing, happy high, perfect for unwinding after a long day.

High yield, minimal effort

This isn’t just another autoflower — it’s a production machine. Indoors, it pumps out 450–500 g/m² (1.5–1.6 oz/ft²) under strong lighting, with plants staying compact at 0.80–0.90 m (2.62–2.95 ft). Outdoors, it can hit up to 800 g (1.75 lb) per plant when grown from April to November. Thanks to its indica-dominant structure and Ruderalis backbone, it thrives in a wide range of conditions without needing advanced techniques.

Get the most out of your grow with this simple, expert-backed plan tailored to the strain’s genetics.

Quick overview

Autoflower from 00 Seeds — 80–90 day cycle, low to medium difficulty, ideal for indoor or outdoor setups in temperate to Mediterranean climates.

• Start in final pot (11–18 L) to avoid root stress
• Use well-aerated soil or coco with Soil Grow for strong root development
• Provide 18–20 hours of light daily with 600W HID or equivalent LED
• Keep temperatures between 22–26 °C (71.6–78.8 °F) in veg, 20–25 °C (68–77 °F) in flower
• Monitor pH: 6.0–6.5 in soil, 5.8–6.2 in coco

Stable seedling

Give your seeds the best start with consistent moisture and protection.

• Germinate in a moist paper towel or starter cube at 22–25 °C (71.6–77 °F)
• Transplant gently when the radicle is ~1 cm (0.4 in) long
• Use Bio-stimulator Growth Booster Max Green Hope to speed up root establishment
• Keep humidity at 60–70% for the first week
• Use low-intensity lighting (200–300 µmol) for the first 3–5 days

Directed growth

Guide your plant for maximum bud sites and airflow.

• Apply gentle LST early to open up the canopy
• Water when the top 2–3 cm (0.8–1.2 in) of soil is dry
• Feed with mild nutrients — avoid nitrogen overload
• Ensure good airflow to prevent humidity buildup
• Use BioTabs Tablets for slow-release nutrition and microbial support

Efficient flowering

Maximize resin and yield during the final stretch.

• Lower humidity to 40–50% to prevent bud rot
• Support heavy colas with soft ties if needed
• Boost flowering with bloom-focused additives in weeks 4–6
• Flush with Canna Flush 7–10 days before harvest
• Watch trichomes: harvest when milky with some amber for full relaxation

Frequently Asked Questions

Is Auto Do-Si-Dos Cookies good for beginners?

Yes — it’s forgiving, fast, and doesn’t require advanced techniques. Just keep it well-lit and avoid overwatering.

Can I grow this outdoors in a colder climate?

Absolutely. Its Ruderalis genes give it resilience to cooler temps and variable weather, especially when planted from April to November.

Does it smell strong during flowering?

Yes — it has a rich, sweet-earthy aroma. Use a carbon filter like those in our Seedfinder grow kits to stay discreet.

Can I use SCROG with this strain?

Yes — its bushy structure responds well to SCROG. Just avoid topping or FIM, as it can stress autoflowers.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Auto Do-Si-Dos Cookies stands out. I ran it in a 1.2 x 1.2 m tent with 600W LED and five plants in 15L pots. I used Soil Grow with BioTabs and kept it simple — no topping, just light LST. By week 10, the room smelled like a bakery with a hint of forest. The buds were rock-hard, covered in trichomes, and tested at 22% THC. The high is smooth — not couch-locking, but deeply calming. I’d rate it 9/10 for flavor, yield, and ease. If you want a reliable, high-impact auto that doesn’t demand perfection, this is it.
