About Rockstar Kush Feminised
The way to plan Rockstar Kush is backwards from the day you intend to cut, with up to 400 g/m2 per square metre indoors and up to 450 g/plant per plant outdoors as the figures you are working toward, at 18% THC. Count 60-65 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 Caryophyllene, then Myrcene, and Bisabolol underneath.
Difficulty: intermediate. In flower for 60-65 days. Stands 70–110 cm. Indoors it returns up to 400 g/m2. Outdoors, up to 450 g/plant a plant.

Rockstar Kush Feminised — 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.
Rockstar Kush began life as a clone-only cut. Translating a clone into seed without losing the bud-to-leaf ratio demands backcrossing — we crossed our chosen pheno back to the parental line three times (BX3) to fix the elite mother into stable seed form.
Translate a clone-only 2010s production cultivar to seed without losing the mother profile.
Chosen for purple/dark expression where it shows, dense bud structure and a true indica relaxation profile.
