About NYC Diesel Auto

Everything about NYC Diesel at harvest follows from one decision, which is when you stop. The figures are 300-350 g/m2 indoors and 75-120 g/plant outdoors, with resin filling towards 20% THC. The 40/60 balance gives steady gain with a lift in the closing fortnight. Outdoors, aim to be finished by mid-October rather than hoping for a dry third week of it.

Where the weight is won

Three parts of the 55-65 days seed to harvest of bloom account for most of the difference between a good result and an average one on a plant rated 300-350 g/m2 indoors and 75-120 g/plant outdoors.

The stretch, days 1-10 after the flip. Canopy height set here decides how evenly light lands for the rest of the run. Around a third is usual. A single pass of training across the tallest shoots keeps the top flat.

Weeks three to five. Caryophyllene production climbs through this stretch and responds to a 6-8°C gap between lights-on and lights-off. Outdoors an Irish September provides that without help; indoors it has to be built, at roughly 25°C by day and 18-20°C at night. Bloom feed goes potassium-forward around EC 1.6-1.8.

The final fortnight. Feeding stops, plain pH-corrected water goes on, and the loupe comes out daily. Ten to fifteen per cent amber sits in the middle of its range. Outdoors, that falls between late September and mid-October, and the forecast gets a say.

Flowering: 55-65 days seed to harvest. Indoor yield: 300-350 g/m2. Outdoor yield: 75-120 g/plant. Plant height: 60-90 cm. Rated beginner difficulty.

Flavour, aroma and effect

NYC Diesel arrives in order. The first draw at 20% THC gives peppercorn heat that lands at the back of the throat. The energetic, happy, uplifted character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Limonene underneath contributes a lift that stops it going heavy.

Terpene breakdown

Primary: Caryophyllene · Secondary: Limonene · Tertiary: Myrcene. This is a combination that turns up repeatedly in cultivars people rate, and it is usually what gets commented on when a jar is opened for the first time after a proper cure. Caryophyllene anchors it, limonene holds the middle, and myrcene sits behind both — the last of those being what separates this from other strains leading on the same terpene.

Who it suits

Who does well with NYC Diesel? Back-garden and balcony growers in Dublin, Cork and Galway. Anyone who wants a crop dry and put away before the autumn closes in. Indoor growers short of headroom. The autoflowering genetics run to their own clock, so there is no schedule to manage and no anxiety about light leaks. Rated beginner, which means a first grow with a basic setup and a bit of discipline about feeding will produce something worth having.

NYC Diesel Auto — Breeder Information

Royal King Genetics

Bred and stabilised in-house by Royal King Genetics — our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read the full breeding process and about page.

Breeding Programme
Royal King Genetics Auto Line — recessive trait stabilisation
Stabilisation Notes — What This Means for Your Grow

Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. NYC Diesel sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.

Breeding Goal

Stabilise the recessive ruderalis trait in NYC Diesel for uniform auto-trigger.

Selection Focus

Chosen for vigour, terpene saturation and a tight finish window that allows production planning.

Pollen / Mother Source

Royal King Genetics select-mother programme — pollen drawn from an internally maintained reversed-female line.
