About Purple Diesel Feminised
Will Purple Diesel handle a South African summer outdoors? Yes. Put this 30/70 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 65-75 days, placing harvest between March and May across most provinces.
What yield is realistic? up to 400 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, up to 800 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 18% THC with limonene 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 30/70 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 65-75 days environment. Outdoors, across a September-to-May season, gives you sunlight intensity no LED at any price reproduces, and the full up to 800 g/plant. Difficulty: easy. In flower for 65-75 days. Stands Short. Indoors it returns up to 400 g/m2. Outdoors, up to 800 g/plant a plant.
Aroma, Flavour and Effect
The first thing Purple Diesel does at 18% THC is lift it with a bright, nearly effervescent citrus. The happy, relaxed, uplifted 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. Pinene sits underneath all of it, adding an alertness that keeps thinking crisp.
The Aromatic Three
Leading with Limonene, then Pinene, and Terpinolene underneath. How this combination survives the move from flower to vapour or smoke is not a given. Held low, at 180-188°C, the pinene and terpinolene notes stay legible with limonene underneath them. Run it hotter, or burn it, and the three collapse into one — still pleasant, but without the separation that makes this cultivar worth paying attention to.
Suitability and Recommendations
Who does well with Purple Diesel? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. It is rated easy, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions.
