About Sour Kush Feminised

The way to plan Sour Kush is backwards from the day you intend to cut, with 600 g/m2 per square metre indoors and 1200 g/plant per plant outdoors as the figures you are working toward, at 26% THC. Count 9-10 weeks back from that date and you have your flip date. Weight comes on evenly across 9-10 weeks, with a late surge that punishes impatience. The 50/50 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot β€” after the summer humidity has broken, before the first Highveld frost.

The Aromatic Three

Leading with Caryophyllene, then Limonene, and Myrcene underneath.

Difficulty: medium. In flower for 9-10 weeks. Stands Medium. Indoors it returns 600 g/m2. Outdoors, 1200 g/plant a plant.

Sour Kush Feminised β€” Breeder Information

Stabilisation Notes β€” What This Means for Your Grow

Sour Kush began life as a clone-only cut. Translating a clone into seed without losing the pack-to-pack uniformity 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

Translate a clone-only recent-era cultivar to seed without losing the mother profile.

Selection Focus

Chosen for hybrid frame, clean terpene expression and consistent yield across the population.

Pollen / Mother Source
