About Lethal Purple Feminised

Lethal Purple announces itself in a fixed order, and limonene is always first out of the jar β€” a citrus lift that arrives before the lid is fully off, lemon rind and tangerine with a sweetness trailing it. caryophyllene follows mid-palate, adding a grounding spice. The lab figure on this 38/62 hybrid 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 Limonene, then Caryophyllene, and Linalool underneath.

Difficulty: intermediate. In flower for 45 – 55 days. Stands Tall. Indoors it returns up to 450 g/m2. Outdoors, up to 450 g/plant a plant.

Lethal Purple 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
Royal King Genetics Backcross Line β€” BX2 modern hybrid stabilisation
Stabilisation Notes β€” What This Means for Your Grow

Lethal Purple carries clone-derived parents from the mid-2010s. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and finish-time consistency run uniform across the population.

Breeding Goal

Pin the finish-time consistency that came out of the original Lethal Purple cross.

Selection Focus

Chosen for balanced indica/sativa expression, terpene fidelity and pack-to-pack uniformity.

Pollen / Mother Source

Royal King Genetics select-mother programme β€” pollen drawn from an internally maintained reversed-female line.
