About NYC Diesel Auto
The way to plan NYC Diesel is backwards from the day you intend to cut, with 300-350 g/m2 per square metre indoors and 75-120 g/plant per plant outdoors as the figures you are working toward, at 20% THC. Count 55-65 days seed to harvest back from that date and you have your flip date. Weight comes on evenly across 55-65 days seed to harvest, with a late surge that punishes impatience. The 40/60 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot — after the summer humidity has broken, before the first Highveld frost.
Where the Weight Actually Comes From
Yield on NYC Diesel — the 300-350 g/m2 indoors and 75-120 g/plant outdoors quoted above — is decided in three short stretches of the 55-65 days seed to harvest bloom rather than evenly across it.
The first ten days after the flip. Whatever stretch happens here sets your canopy, and an uneven canopy wastes light for the remainder of the grow. Stretch of 30-40% is normal. One round of low-stress training on the tallest shoots levels it out.
Weeks three to five. This is when caryophyllene production climbs, and it answers to the gap between day and night temperature rather than to either number on its own. Keep at least 6-8°C between them. Outdoor growers in the interior provinces get that swing free in March and April; indoors, aim for 25-26°C lights-on against 18-20°C lights-off, with potassium-led bloom feed at EC 1.6-1.8.
The last ten to fourteen days. Stop feeding, flush with pH-corrected water, and read trichomes daily under a 60x loupe. Cut at 10-15% amber to keep both sides of the hybrid in play. Outdoors that usually lands between late March and mid-April.
Difficulty: beginner. In flower for 55-65 days seed to harvest. Stands 60-90 cm. Indoors it returns 300-350 g/m2. Outdoors, 75-120 g/plant a plant.
Aroma, Flavour and Effect
The first thing NYC Diesel does at 20% THC is settle a warm peppery spice at the back of the throat. The energetic, happy, uplifted effects follow within minutes, across head and body at once. Thinking stays clear while muscle tension drains off, which leaves the dose as the deciding factor — light for the afternoon, heavier and it moves into the evening without a jolt. Limonene sits underneath all of it, adding a brightness that offsets any heaviness.
The Aromatic Three
Leading with Caryophyllene, then Limonene, and Myrcene underneath. This trio turns up repeatedly in cultivars that win things, and it is why a jar of NYC Diesel tends to get a reaction the first time it is opened after curing. Caryophyllene sets the anchor, limonene fills the middle, and myrcene sits in the background doing the work that separates this from every other strain built on the same primary terpene.
Suitability and Recommendations
Who does well with NYC Diesel? People growing on flat balconies from Cape Town to Johannesburg. Smallholders after a fast outdoor crop. Indoor growers short on headroom. Autoflowering genetics run to their own clock, so there is no light schedule to hold, no worrying about light leaks, and harvest lands 10-12 weeks from germination whatever the season is doing. It is rated beginner, which in practice means a first-time grower with a basic setup and a feeding schedule they actually follow will get a decent result.

NYC Diesel Auto — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics , the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
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.
Stabilise the recessive ruderalis trait in NYC Diesel for uniform auto-trigger.
Chosen for vigour, terpene saturation and a tight finish window that allows production planning.
