About Purple Star Auto

The way to plan Purple Star is backwards from the day you intend to cut, with up to 250 g/m2 per square metre indoors and up to 350 g/plant per plant outdoors as the figures you are working toward, at 10% THC. Count 50-60 days back from that date and you have your flip date. Most of the final weight lands between weeks 5 and 8, when calyxes stack fastest and trichome cover goes from patchy to complete. Outdoors in the Southern Hemisphere you want that fattening phase falling in February while the days are still long, which puts a late-March cut about right for most of the country.

The Aromatic Three

Leading with Myrcene, then Caryophyllene, and Linalool underneath.

Difficulty: easy. In flower for 50-60 days. Stands 90-120 cm. Medium. Indoors it returns up to 250 g/m2. Outdoors, up to 350 g/plant a plant.

Purple Star Auto β€” Breeder Information

Royal King Genetics

Recreated 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.

Stabilisation Level

Generations
5+
Breeding Programme
Autoflower Stabilisation (F5) β€” ruderalis trait fixing
Stabilisation Notes β€” What This Means for Your Grow

Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. Purple Star sits at F5 β€” every plant in the pack autoflowers reliably and finishes inside a tight window.

Breeding Goal

Stabilise the recessive ruderalis trait in Purple Star for uniform auto-trigger.

Selection Focus

Chosen for purple/dark expression where it shows, dense bud structure and a true indica relaxation profile.

Pollen / Mother Source

Royal King Genetics in-house breeder room β€” pollen taken from a generation-tracked sibling-male line.
