Do-si-dos Automatic by Royal Queen Seeds – Fast, Potent & High-Yielding Autoflower with 20% THC

Do-si-dos Automatic by Royal Queen Seeds is a high-octane autoflower that delivers up to 20% THC and impressive yields in just 70–75 days, making it a top choice for fast, potent, and reliable harvests.

Are You Still Waiting Months for a Single Harvest?

Most autoflowers make you choose: speed or power. You end up stuck with weak buds or long waits. It’s frustrating when you just want quality results without the hassle.

Why Settle for Slow or Weak When You Can Have Both?

Waiting 12 weeks for mediocre THC or low yields kills your momentum. You miss out on perpetual harvests, waste space, and lose the chance to experiment. That limited approach means less stash, less fun, and more stress.

Do-si-dos Automatic: Power, Speed, and Simplicity in One Plant

Meet the autoflower that breaks the mold. Do-si-dos Automatic packs 20% THC, finishes in 70–75 days, and produces up to 400g/m². Whether you're a stealthy indoor grower or a backyard cultivator, this strain adapts and delivers—no compromises.

Indoor Powerhouse: Maximize Yield in Minimal Space

Inside, Do-si-dos Automatic stays compact at 0.80–1.20 m (2.62–3.94 ft), perfect for small tents or stealth grows. Under a 250W LED, she fills the space with dense, frosty colas in under 10 weeks. Use low-stress training (LST) early to spread the canopy and boost light penetration. With proper airflow and a carbon filter, you’ll avoid odors and mold while harvesting up to 400g/m² (1.32 oz/ft²). Pair her with Kit Hesi Starterbox Hydro for a seamless setup from seed to harvest.

Outdoor Flexibility: Discreet, Resilient, and Rewarding

Outside, she stretches to 1.40 m (4.59 ft), blending in with companion plants like basil or lavender to mask her sweet, skunky scent. She handles Mediterranean and temperate climates with ease, resisting mold and pests when airflow is good. Sow in a 20L pot with well-draining soil and let her shine under full sun. Expect 100–150 g/plant (3.53–5.29 oz/plant), with peak harvest in late September to October in the Northern Hemisphere. Her balanced indica-sativa effect lets you enjoy her after work without locking you to the couch.

How to Choose the Best Setup for You

Still unsure where she’ll thrive best? Here’s how to decide:

• If you value discretion and control, indoor growing gives you consistent, high-quality results.
• If you love nature and have a sunny spot, outdoor growing maximizes free sunlight and plant size.
• If you're new to growing, her low-maintenance nature and fast cycle make her a stress-free win.
• If you're experienced, use her for perpetual harvests—sow new seeds every 2–3 weeks.

How to grow Do-si-dos Automatic seeds

Quick overview: autoflowering · Royal Queen Seeds · 70–75 days · low difficulty · ideal for indoor tents or sunny patios.

Safe start: Germinate in a damp paper towel at 22–25 °C. Transplant when the taproot is 1 cm long. For faster rooting, Rhizotonic XP boosts early root development.

Stable seedling: Keep humidity at 60–70%. Use a light, airy soil mix. Water lightly and avoid nutrients for the first week. A mycorrhizal inoculant helps build resilience.

Directed growth: Provide 18–20 hours of light daily. Transplant to a 20L pot early. Apply BN-Roots - Biomineral root system enhancer - Bio Nova to strengthen roots and prevent stress.

Efficient flowering: Maintain humidity at 40–50%. Support heavy colas with stakes. In mid-flower, a bloom booster like Brutal Bloom Flowering Booster increases density and resin production.

Harvest and refinement: Harvest when trichomes are mostly milky with some amber. Flush 7–10 days before harvest. Dry at 18–22 °C and 50–60% RH for 7–10 days, then cure in jars for 2–4 weeks.

Frequently Asked Questions

Can I grow Do-si-dos Automatic outdoors in a cold climate?

Yes, she tolerates mild cold, but thrives best in temperate or Mediterranean climates. Protect her from frost and heavy rain to avoid mold.

How many plants do I need for a personal supply?

One well-grown plant can yield 100–150 g, enough for several weeks of regular use. For a perpetual harvest, grow 3–4 plants on staggered schedules.

Can I use LST on this autoflower?

Absolutely. Low-stress training works great to open up the canopy. Just avoid topping or FIM, as autos have less time to recover.

What nutrients work best with Do-si-dos Automatic?

She’s not a heavy feeder. Use a balanced organic or mineral base. Add a PK booster in mid-flowering for bigger buds. Overfeeding can cause nutrient burn.

When should I harvest for a more energetic effect?

Harvest earlier when most trichomes are milky. For a more relaxing high, wait until more turn amber.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Do-si-dos Automatic stands out. I ran three in a 1.20 x 1.20 m tent under a 250W LED, and they filled the space in 9 weeks. I used LST at week 2 to spread the canopy, and the buds came out thick and frosty. The smell during flowering was intense—sweet, skunky, with a hint of citrus—so I kept my carbon filter on. I flushed for 10 days and dried slowly. The high is smooth: it starts cerebral, then melts into a deep body relaxation. It’s perfect for unwinding after a long day without knocking me out. I’d recommend this to anyone, from first-timers to seasoned growers. It’s reliable, potent, and delivers every time.
