NYC Sour D

NYC Sour D Autoflower Cannabis Seeds

NYC Sour D Autoflower is a sativa-dominant autoflowering cannabis seed born from a collaboration between Royal Queen Seeds and Tyson 2.0 — Mike Tyson's cannabis brand. A cross of NY Diesel and Sour Diesel Auto, this cultivar packs gassy, citrus-forward terpenes into a compact plant that finishes in roughly 12 weeks from germination. If you want diesel genetics without the fuss of photoperiod lighting schedules, this is the seed to drop.

Why NYC Sour D Autoflower Seeds Deserve a Spot in Your Grow

The Sour Diesel lineage has been a cornerstone of East Coast cannabis culture for decades. What Royal Queen Seeds and Tyson 2.0 have done here is distil that legacy into a seed that practically grows itself. NYC Sour D Autoflower doesn't need a light cycle change to flip into flower — she'll do it on her own, roughly three weeks after germination, regardless of your lighting schedule. That alone removes one of the biggest headaches for newer growers.

But the real draw is what happens after harvest. Dried and cured buds carry that unmistakable diesel funk — fuel-forward, sharp, with a citrus sourness that hits the back of your throat. It's not subtle. If you've ever cracked open a bag of proper Sour Diesel and had the whole room turn their heads, you know the profile. The gassy terpenes on this one are the real deal.

One honest limitation: autoflowers generally produce less per plant than their photoperiod cousins. You're trading raw yield for speed and simplicity. If you're chasing absolute maximum harvests and don't mind managing light schedules, Royal Queen Seeds' photoperiod Sour Diesel might be more your speed. But if you want a fast, forgiving grow with genuinely impressive terps, NYC Sour D Auto is hard to beat.

NYC Sour D Autoflower Growing Characteristics

This autoflower is built for growers who want results without drama. From germination to harvest, you're looking at approximately 12 weeks — that's seed to chop in about three months. No light schedule manipulation, no sexing plants, no waiting for autumn to trigger flowering outdoors.

Indoors, expect a compact plant around 80cm tall — she fits comfortably in an 80x80cm tent without dominating the canopy. Despite her small stature, yields can reach up to 500g/m² under good light (think 18/6 or 20/4 throughout the entire cycle). Outdoors, plants stretch to about 150cm and produce roughly 180g per plant, which is a solid return for an autoflower of this size.

Terpene Profile and Flavour of NYC Sour D Auto

The flavour on this strain is where it truly earns its name. Crack a cured bud open and you'll get hit with sharp diesel fuel notes first — that classic Sour D pungency that sticks to your fingers. Behind that initial gassy wave comes a citrus brightness, almost like someone squeezed a grapefruit over a petrol station forecourt. There's a sour tang that lingers on the exhale, rounded out by subtle fruity undertones that keep things interesting.

The aroma fills a room quickly. If discretion matters to your grow setup, a carbon filter isn't optional with this one — the terpene output is genuinely intense. We've had customers tell us the smell during the final two weeks of flower is borderline antisocial. That's the diesel lineage doing its thing.

Effects of NYC Sour D Autoflower

With approximately 21% THC and sativa-dominant genetics, NYC Sour D Auto delivers a cerebral, uplifting experience. According to research examining patient-reported effects, sativa varieties have a reputation for producing more cerebral and stimulating effects while indica varieties tend toward more sedative outcomes (Pearce et al., 2018, PMC6275121). This aligns with what you'd expect from the Sour Diesel lineage — a motivating, clear-headed experience rather than a couch-lock situation.

The effects tend to come on relatively quickly and can last 2–3 hours for most people, gradually tapering into a smooth comedown. According to research published in Medical News Today, cannabis groups in a comparative study reported some reduction in anxiety, though individual responses varied (CBD vs. THC, MedicalNewsToday). If you're new to strains in this THC range, the standard advice from clinical guidance applies: start low, go slow — one or two puffs, then wait 10–15 minutes before deciding if you want more.

How to Grow NYC Sour D Autoflower Seeds

1. Germinate your seeds. Use the paper towel method or soak directly in a glass of water for 12–24 hours until taproots appear. Handle seeds with clean hands or tweezers — contamination from skin oils is a real thing.
2. Plant into final containers. Autoflowers don't love being transplanted. Go straight into your final pot — 11–15 litres is the sweet spot. Use a light, airy growing medium with good drainage.
3. Set your lights. Indoors, run 18 hours on, 6 hours off from day one through harvest. Some growers push to 20/4 for extra growth. Unlike photoperiod strains, you never need to switch to 12/12.
4. Feed lightly. Autoflowers are smaller and more sensitive to overfeeding than photoperiod plants. Start at half the recommended nutrient dose and increase only if the plant asks for it (pale leaves, slow growth).
5. Watch for pre-flowers around week 3–4. NYC Sour D Auto will begin flowering automatically. You'll see white pistils forming at the nodes — that's your signal to transition to bloom nutrients.
6. Maintain airflow and humidity. During flower, keep relative humidity below 50% to prevent mould in those dense buds. A small oscillating fan does wonders.
7. Harvest around week 10–12. Check trichomes with a jeweller's loupe — milky white with a few amber trichomes indicates peak ripeness. Chop, dry slowly over 7–10 days at 18–20°C, then cure in glass jars for at least two weeks.

NYC Sour D Auto Compared to Other Autoflower Seeds

If you want something faster and milder, Northern Light Auto finishes a couple of weeks earlier and sits at a more approachable 14% THC — a good pick for newer growers who want a gentler introduction. Hulkberry Auto matches NYC Sour D on potency but swaps the diesel funk for sweeter berry notes. We'd pick NYC Sour D Auto specifically for that gassy, sour terpene profile — nothing else in the Royal Queen Seeds autoflower range quite nails that old-school East Coast diesel character.

Safety and Interactions

This content is written for adults aged 18 and over. Cannabis seeds are sold as collector's items and for cultivation where permitted.

At approximately 21% THC, NYC Sour D Auto produces potent flower. According to research, adverse effects of cannabis can include fatigue, increased drowsiness, and changes in appetite (PMC11171823). High-THC sativa varieties may occasionally cause racing thoughts or anxiety in sensitive individuals, particularly at higher doses.

Cannabis may interact with certain medications. Research indicates that MAOIs (monoamine oxidase inhibitors) may prolong or intensify CNS-depressant effects when combined with other substances. If you take prescription medication — particularly antidepressants, blood thinners, or sedatives — speak with your doctor before using cannabis products.
