Royal Kush Automatic seeds from Royal Queen Seeds give you fast, high-quality harvests in just 11–12 weeks from seed to smoke, delivering a smooth, uplifting high and unmistakable Kush flavor without the hassle.

Feeling overwhelmed by complicated grows and unpredictable results? You’re not alone. Many beginners jump in excited, only to face stunted plants, weak yields, or endless waiting with no clear roadmap. Even experienced growers can get tripped up when they skip steps or rush the process.

Without a clear plan, it’s easy to make mistakes—overwatering seedlings, pruning too late, or harvesting at the wrong time. These small errors add up, leaving you frustrated and wondering if the strain just “doesn’t work.” But the truth? Most failures come from the process, not the plant.

That’s where Royal Kush Automatic changes the game. This autoflowering powerhouse follows a simple, predictable growth cycle—no guesswork, no complicated light schedules. Just plant, follow the phases, and watch it thrive. With its resilient genetics and forgiving nature, it guides you step by step to a rewarding harvest, whether you’re growing in a closet or on a balcony.

Preparation: Set Up for Success

Before you even crack the seed, make sure your environment is ready. Royal Kush Automatic thrives when conditions are stable from day one.

• Choose a location with consistent temperatures between 22–26 °C (71.6–78.8 °F)
• Use pots of 18–27 L (6.35–9.54 gal) to avoid transplant stress
• Prepare a well-draining soil mix or coco substrate with good aeration
• Ensure access to 18–20 hours of light daily throughout the cycle
• Check pH levels: 6.0–6.5 for soil, 5.8–6.2 for coco

Germination and Early Growth

Start strong with a solid foundation. This strain sprouts quickly, so be ready to act.

1. Germinate seeds using the paper towel method or directly in soil
2. Keep humidity high (60–70%) and temperature around 22–25 °C (71.6–77 °F)
3. Water lightly—just enough to keep the medium moist, not soaked
4. Transplant once the taproot reaches about 1 cm (0.39 in)
5. Place under consistent light to prevent stretching

Vegetative and Flowering Development

1. Allow natural growth—avoid topping or aggressive training due to its autoflowering nature
2. Apply gentle LST (Low Stress Training) if needed to control height
3. Maintain humidity at 50–60% during early growth, dropping to 40–50% in flowering
4. Feed with balanced nutrients, increasing phosphorus and potassium as flowering begins
5. Monitor for signs of maturity: dense, neon green buds forming by week 6–7
6. Expect a strong, spicy-kush aroma in late flowering—consider a carbon filter if discretion is key

Harvest, Drying and Curing

Finish strong and preserve quality. Timing is everything.

1. Harvest between 50–55 days after sprouting, when trichomes turn milky to amber
2. Cut branches and trim excess leaves for better airflow
3. Dry slowly at 18–22 °C (64.4–71.6 °F) and 50–60% humidity for 7–10 days
4. Cure in airtight jars, opening daily for the first two weeks
5. Enjoy smoother flavor and enhanced effects after 2–4 weeks of curing

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown Royal Kush Automatic both indoors and on my rooftop, and it never fails to impress. I started with three seeds in 20L pots, using a simple soil mix with Plagron Top Grow Box Soil—it gave me consistent results without overcomplicating things. The plants stayed under 90 cm, perfect for my stealth setup. By week 8, the buds were already dense and aromatic. I didn’t top them—just a little LST to spread the canopy. One thing I learned: don’t overfeed. I pushed nutrients too hard the first time and got minor burn. Backed off, and the next harvest was smooth, resinous, and flavorful. It’s now one of my go-to strains for quick turnarounds and reliable quality.
