About NYC Sour Diesel Auto
Will NYC Sour Diesel handle a South African summer outdoors? Yes. Put this 11/89 sativa in the ground between September and November and you will be cutting from March to May. It will stretch, and it will use every hour of a long summer day, so give it room early rather than trying to contain it later. Bloom runs 55-65 days flowering (75-90 days seed to harvest), placing harvest between March and May across most provinces.
What yield is realistic? up to 500 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, up to 180 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 15% THC with pinene in front, the return on effort is good.
How much can go wrong before it shows? Some. Anyone who understands pH, a feeding schedule and a light cycle will be fine. Neglect it entirely and it will suffer, but a single missed watering will not undo the grow.
Further Questions from South African Growers
Which medium suits it best? Depends what you are optimising for. Organic soil cut with 30% perlite and amended with bone meal, rock phosphate and kelp meal gives the fuller flavour, and all three are stocked by garden centres, agricultural co-ops and hydro shops countrywide. Coco under automated fertigation at EC 1.4-1.8 through bloom gives the bigger number. This sativa genetics performs in either.
Does it cope with real summer heat? Better than most things you could plant. An open canopy sheds heat on its own. Past 38°C you may see midday wilt, but it recovers within the hour once temperatures fall — 30% shade cloth takes the edge off the UV without costing you growth.
When do I switch to bloom feed? As soon as pistils show, not a fortnight later. The 11/89 genetics changes its demand sharply at the transition: phosphorus and potassium uptake rises while nitrogen demand falls away. Soil growers can top-dress with guano and sulphate of potash; coco and hydro growers should move to a low-N, high-PK formula immediately.
Indoors or outdoors? Indoors buys control over the 55-65 days flowering (75-90 days seed to harvest) environment. Outdoors, across a September-to-May season, gives you sunlight intensity no LED at any price reproduces, and the full up to 180 g/plant. Difficulty: intermediate. In flower for 55-65 days flowering (75-90 days seed to harvest). Stands 80 cm. Indoors it returns up to 500 g/m2. Outdoors, up to 180 g/plant a plant.
Aroma, Flavour and Effect
The first thing NYC Sour Diesel does at 15% THC is arrive clean and resinous, like a pine plantation in the mist belt after rain. The euphoric, creative, energetic, calm effects follow within minutes, as a sharpening rather than a lift: colour reads more saturated, music holds more detail, conversation wanders further than it would have. It runs two to three hours on a plateau instead of a peak, so nothing drops out from under you at the end. Limonene sits underneath all of it, adding a brightness that offsets any heaviness.
The Aromatic Three
Leading with Pinene, then Limonene, and Caryophyllene underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, pinene leads. After three or four weeks in sealed glass at 16-18°C the caryophyllene undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile caryophyllene molecules are the first thing you lose.
Suitability and Recommendations
Who does well with NYC Sour 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 intermediate, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions.
