About Sour Kush Feminised

Here is what Sour Kush delivers at harvest, with resin production peaking at 26% THC. The picture comes together when you work backwards through the 9-10 weeks window. Weight distribution across the 9-10 weeks cycle is pleasingly even, with a noticeable surge in the closing two weeks that rewards growers who resist harvesting prematurely. The 50/50 balance means you get both calyx stacking density and respectable trichome spread. For outdoor growers, the ideal harvest window lands between mid-March and mid-April — early enough to dodge late-autumn moisture in most states, late enough to capture the full caryophyllene terpene development.

Maximising Your Harvest

To reach the upper end of this strain's yield potential, focus your efforts on three critical windows during the 9-10 weeks period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Moderate 30-40% stretch is typical. One round of low-stress training on the tallest shoots keeps everything level.

Window 2: Weeks 3-5 of bloom. Caryophyllene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8°C to encourage terpene accumulation — New Zealand autumn evenings (March-April) naturally provide this swing for outdoor growers. Indoor cultivators should target 25-26°C during lights-on and 18-20°C during lights-off. Supplement with potassium-heavy bloom nutrients at EC 1.6-1.8.

Window 3: Final 10-14 days before harvest. Cease all nutrient input and flush with pH-adjusted water. Monitor trichomes daily with a 60x jeweller's loupe — harvest at 10-15% amber for a balanced effect. Southern Hemisphere outdoor growers: this window typically falls in late March through mid-April.

Flowering: 9-10 weeks. Indoor yield: 600 g/m2. Rated intermediate difficulty.

Flavour, Aroma, and Experience

The sensory arc of Sour Kush unfolds in stages. Initial inhalation at 26% THC brings a warm peppery spice that tingles at the back of the throat. The relaxed, happy, euphoric effects emerge within minutes, presenting as a simultaneous head-and-body experience. Mental clarity remains intact whilst the muscles release tension progressively. This dual action makes it adaptable — a lighter dose suits afternoon tasks, a heavier dose transitions seamlessly into evening relaxation. The limonene secondary terpene adds a distinct layer: a mood-elevating brightness that counterbalances any heaviness.

Terpene Breakdown

Primary: Caryophyllene · Secondary: Limonene · Tertiary: Myrcene. This particular terpene trio appears frequently in award-winning cultivars and produces a nose that most growers find immediately appealing when jars are first opened after curing. The caryophyllene dominance anchors the aroma, limonene provides mid-range character, and myrcene contributes a subtle background note that distinguishes this strain from others sharing the same primary terpene.

Suitability and Recommendations

Who grows Sour Kush successfully? Indoor growers seeking full control over their harvest timeline. Outdoor cultivators who want to decide exactly when flowering begins. Anyone with the space and patience to vegetate this plant to its full potential before triggering bloom. Difficulty is rated intermediate, meaning a moderate learning curve that rewards attention without demanding laboratory-grade conditions. Delivered nationwide in discreet, unbranded packaging with sourced grow data on every strain page.

Stabilisation Notes — 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 — 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.
