About OG #18 Feminised

OG #18 announces itself in a fixed order, and terpinolene is always first out of the jar β€” a herbal bouquet that resists being placed, part rosemary and part crisp apple, with a floral edge that shifts the longer you breathe it in. limonene follows mid-palate, adding a bright citrus edge. The lab figure on this 22/78 sativa is 20% THC, though potency is the least interesting thing about it β€” plenty of cultivars test the same and taste of very little.

The Aromatic Three

Leading with Terpinolene, then Limonene, and Ocimene underneath.

Difficulty: intermediate. In flower for 9 weeks. Stands Short. Indoors it returns 500-600 g/m2. Outdoors, 595 g a plant.

OG #18 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.

Generations

Breeding Programme
Royal King Genetics Backcross Line β€” BX3 clone-only restabilisation
Stabilisation Notes β€” What This Means for Your Grow

OG #18 began life as a clone-only cut. Translating a clone into seed without losing the haze-character terps demands backcrossing β€” we crossed our chosen pheno back to the parental line three times (BX3) to fix the elite mother into stable seed form.

Breeding Goal

Pin the haze-character terps of the elite cut into the population.

Selection Focus

Chosen for sativa vigour, bud-to-leaf ratio and the distinctive terpene character of the original cut.

Pollen / Mother Source

Royal King Genetics breeding facility β€” pollen from internally selected sibling males of the recurrent parent.
