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.
NYC Sour D Autoflower seeds come in four pack sizes: 1, 3, 5, and 10 seeds. If you're running a single plant to test the genetics, the 1-pack does the job. For a proper run that lets you pick the best phenotype, grab the 5 or 10-pack — more seeds means more chances to find a standout keeper.
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.
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.
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.
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.
Running NYC Sour D Auto indoors? Pair these seeds with a complete grow tent kit — tent, light, fan, and carbon filter in one box. The carbon filter is non-negotiable with this strain's diesel terpene output. If you're growing outdoors, a fabric pot (15–20 litres) gives roots the air-pruning they need for healthy autoflower development.
| Strain | Genetics | Seed to harvest | Indoor yield | THC | Dominant terpenes |
|---|---|---|---|---|---|
| NYC Sour D Auto (RQS x Tyson 2.0) | NY Diesel x Sour Diesel Auto | ~12 weeks | Up to 500g/m² | ~21% | Diesel, citrus, sour |
| Northern Light Auto (RQS) | Northern Light autoflower | ~9–10 weeks | Up to 500g/m² | ~14% | Earthy, sweet, pine |
| Hulkberry Auto (RQS) | Hulkberry autoflower | ~10–11 weeks | Up to 450g/m² | ~21% | Sweet, berry, citrus |
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.

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.
About 12 weeks from germination to harvest. She'll begin flowering automatically around week 3–4 without any change to your light schedule. Indoor and outdoor timelines are roughly the same.
Sharp diesel fuel up front, followed by sour citrus and a fruity finish. The aroma is intense — expect your grow space to reek of fuel and grapefruit during the final weeks of flower. A carbon filter is strongly recommended indoors.
Yes. Autoflowers remove the complexity of light schedule management entirely. NYC Sour D Auto is feminised, so no males to identify and remove. Feed lightly, keep humidity in check, and she'll do the rest.
Indoors, up to 500g/m² under optimised conditions. Outdoors, around 180g per plant. Actual results depend on your light, nutrients, and growing medium — but these figures are realistic, not marketing fantasy.
Indoors she stays compact at roughly 80cm — fits easily in a standard grow tent. Outdoors, plants can reach about 150cm. She won't tower over your garden fence.
NYC Sour D Auto is autoflowering and feminised — she flowers on her own schedule regardless of light hours, and every seed produces a female plant. Photoperiod Sour Diesel requires a 12/12 light switch to trigger flowering and typically yields more per plant but takes longer.
Absolutely. She'll flower regardless of day length, so you can plant her outdoors from spring through summer in most European climates. Plants reach about 150cm outdoors and produce around 180g each.
