About Master Kush Feminised

The way to plan Master Kush is backwards from the day you intend to cut, with Up to 600 gr./m2 per square metre indoors and Up to 700 gr./plant per plant outdoors as the figures you are working toward, at 21% THC. Count 50-55 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 Linalool, then Myrcene, and Caryophyllene underneath.

Difficulty: easy. In flower for 50-55 days. Stands Short. Indoors it returns Up to 600 gr./m2. Outdoors, Up to 700 gr./plant a plant.

Master Kush Feminised 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.

Breeding Programme
IBL Heritage Programme β€” five-generation inbred fixing
Stabilisation Notes β€” What This Means for Your Grow

One of the longest-running stabilisation projects in our catalogue. Master Kush traces its origins to late-1990s legacy stock, and the Royal King Genetics team has layered five generations of inbred selection on top. Pheno drift has been pulled out of the line; pack-after-pack, what you grow runs true.

Breeding Goal

Restabilise a late-1990s legacy cultivar to contemporary uniformity standards.

Selection Focus

Chosen for resin density, indica-leaning frame and tight internodes that suit indoor production.

Pollen / Mother Source

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