About Purple Dragon Auto
Purple Dragon announces itself in a fixed order, and linalool is always first out of the jar — soft lavender with a powdery sweetness behind it, like a garden an hour after rain. myrcene follows mid-palate, adding an earthy floor. The lab figure on this 66/34 indica is 18% THC, though potency is the least interesting thing about it — plenty of cultivars test the same and taste of very little.
Growing for Aroma Rather Than Weight
The choices that bring out the Linalool/Myrcene/Caryophyllene profile in Purple Dragon are not the choices that maximise yield, and at some point you have to pick one. The aromatic version starts in living soil — microbial activity in an established no-till bed produces secondary metabolites a synthetic feed schedule never will, and South Africa has enough good local compost and worm-casting suppliers to make that affordable rather than aspirational.
Through 50-60 days, stop foliar spraying after week two: anything that lands on a developing trichome is still there at harvest. The closing three weeks decide which terpenes end up in front — nights held at 16-18°C push linalool forward, a warmer finish protects the lighter caryophyllene top notes, and you cannot have both. Decide which version of the strain you want before you get there.
Most of the loss happens after the cut. Hang for 10-14 days at 15-18°C and 55-60% humidity, which through a South African summer realistically means a climate-controlled room or a wine fridge set to 16°C. Then jar it and burp twice daily for the first fortnight. The myrcene layer that makes this cultivar worth the trouble does not surface until somewhere between day 21 and day 28 in glass.
Difficulty: easy. In flower for 50-60 days. Stands 90-120 cm. Medium. Indoors it returns up to 350 g/m2. Outdoors, up to 400 g/plant a plant.
What Purple Dragon Is Like to Use
The effects most commonly reported for this cultivar are creative, focused, calm. At 18% THC it sits in a bracket where the dose does most of the work. A single bowl vaporised at 185°C gives a manageable body relaxation with your head still intact — enough to close out a long day in the summer heat. Push the dose and it moves decisively toward physical sedation, which is how it tends to end up as a winter evening cultivar. The Linalool/Myrcene pairing leaves a shifting profile that keeps turning up new notes on the palate.
Where it fits: quiet evenings, a film, recovery after exercise, and the hours before sleep.
The Aromatic Three
Leading with Linalool, then Myrcene, and Caryophyllene underneath. How this combination survives the move from flower to vapour or smoke is not a given. Held low, at 180-188°C, the myrcene and caryophyllene notes stay legible with linalool 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
Purple Dragon is a reasonable fit for growers with the basics already in place. Understand pH, know roughly what nutrient ratios do, and be able to hold a light cycle — it will not carry you, but it does not punish the occasional slip either. Because it autoflowers there is no light cycle to manage at all, which is what makes it work on a balcony, in an out-of-the-way outdoor spot, or anywhere a timer would be one more thing to go wrong. A September-to-May outdoor season comfortably covers a 50-60 days bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.

Purple Dragon 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. Purple Dragon sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.
Stabilise the recessive ruderalis trait in Purple Dragon for uniform auto-trigger.
Chosen for trichome coverage, stout structure and consistent flowering time across the pack.
