Diesel Auto Royal Queen Seeds – Fast 8-Week Harvests & NYC Diesel Flavor

Diesel Auto Royal Queen Seeds delivers the unmistakable taste and clear high of New York City Diesel in a fast, easy-to-grow autoflowering package that finishes in just 8–9 weeks, perfect for beginners and veterans alike.

Struggling to grow classic sativa-dominant strains without the stress, space, or time?

Most legendary strains like NYC Diesel demand long grow cycles, expert care, and perfect conditions — and even then, they can be finicky, stretchy, and vulnerable to mold. Miss a feeding or a humidity spike, and your harvest suffers. Plus, their strong odor can be a dead giveaway.

Meet Diesel Auto — the no-stress, high-reward solution that brings the iconic diesel punch and citrus zing to your grow space in record time, without the hassle.

Enjoy NYC Diesel Flavor in Half the Time

Diesel Auto cuts the wait dramatically, going from seed to harvest in just 55–65 days. You get the same bold, chemical-diesel aroma with a bright citrus twist, minus the 3-month wait. Whether you're in a small tent, a closet, or growing outdoors discreetly, this compact powerhouse (40–70 cm indoors) delivers up to 375g/m² of aromatic, trichome-covered buds. It’s the perfect way to enjoy a modern classic without the commitment.

How to grow Diesel Auto seeds for maximum yield

1. Start with fresh seeds and germinate in a moist paper towel or directly in a light, airy substrate like Alga Grow Plagron.
2. Transplant carefully into a final pot of 18–27 L to avoid root stress; use soil or coco with good drainage.
3. Provide 18–20 hours of light daily; keep temperatures at 22–26 °C during veg and 20–25 °C in flowering.
4. Water when the top inch of soil feels dry; avoid overwatering, especially in late flowering.
5. Apply light nutrients early, increasing gradually; avoid heavy feeding to prevent nutrient burn.
6. Use low-stress training (LST) early to shape the plant, but avoid topping or aggressive pruning.
7. Harvest when 70% of trichomes turn from clear to milky; expect dense, resinous colas in 8–9 weeks.

Care, maintenance and storage of seeds

Store seeds in a cool, dark, dry place — ideally in their original packaging inside an airtight container. A refrigerator (not freezer) at 4–8 °C is perfect for long-term storage. Keep them away from light, heat, and humidity to maintain high germination rates for up to 5 years. Once planted, ensure consistent watering and avoid pH swings (keep soil at 6.0–6.5) to support strong root development.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Diesel Auto in my 1.20 x 1.20 m (4 x 4 ft) tent under a 600W LED. I used a soil mix with Start Up Plagron and kept it simple. No topping, just light LST. It stayed short at 65 cm (25.6 in), filled the space evenly, and smelled like a NYC taxi garage — in the best way. I harvested 310 grams (10.94 oz) after 63 days. The high is clean, social, and motivating — not overwhelming. It’s one of my go-to autos for a fast, flavorful, and reliable harvest. Just watch the smell if you're not using a filter.
