About Mandarin Auto
Will Mandarin handle a South African summer outdoors? Yes. Put this 36/64 hybrid in the ground between September and November and you will be cutting from March to May. The balanced genetics take what the country gives them, from coastal humidity in KwaZulu-Natal through to dry Karoo heat. Bloom runs 45 – 55 days, placing harvest between March and May across most provinces.
What yield is realistic? up to 300 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, up to 200 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 18% THC with myrcene 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.
The Aromatic Three
Leading with Myrcene, then Limonene, and Pinene underneath.
Difficulty: easy. In flower for 45 – 55 days. Stands Short. Indoors it returns up to 300 g/m2. Outdoors, up to 200 g/plant a plant.

Mandarin 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.
Mandarin is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the cross-derived trait balance the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.
Reach auto trigger and finish-window uniformity for the Mandarin pack.
Chosen for vigour, terpene saturation and a tight finish window that allows production planning.
