About Supergirl Feminised

Here is what Supergirl delivers at harvest, with resin production peaking at 26% THC. The picture comes together when you work backwards through the 7-9 weeks window. The bulk of your final weight accumulates during weeks 5 through 8 β€” a period where the 88/12 genetics stack calyxes rapidly and trichome coverage shifts from scattered to frosted. Southern Hemisphere outdoor growers targeting a late-March harvest should calculate their flip date (or natural light trigger) accordingly, aiming for buds to enter this critical fattening stage during February when daylight hours are still generous.

Maximising Your Harvest

To reach the upper end of this strain's yield potential, focus your efforts on three critical windows during the 7-9 weeks period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Expect modest stretch of 20-30% β€” a quick defoliation of lower fan leaves at day 7 redirects energy to developing bud sites.

Window 2: Weeks 3-5 of bloom. Myrcene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8Β°C to encourage terpene accumulation β€” New Zealand autumn evenings (March-April) naturally provide this swing for outdoor growers. Indoor cultivators should target 25-26Β°C during lights-on and 18-20Β°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 β€” harvest at 15-20% amber for the full-bodied effect this genetics is known for. Southern Hemisphere outdoor growers: this window typically falls in late March through mid-April.

Flowering: 7-9 weeks. Indoor yield: 450-550 g/m2 (SOG). Rated intermediate difficulty.

Flavour, Aroma, and Experience

The sensory arc of Supergirl unfolds in stages. Initial inhalation at 26% THC brings a deep, musky earthiness that coats the palate. The relaxed, sleepy, happy effects emerge within minutes, beginning as a pleasant heaviness behind the eyes that migrates downward through the shoulders, chest, and limbs. By the fifteen-minute mark, a deep physical stillness sets in β€” not sedation exactly, but a reluctance to move that makes the couch remarkably appealing. Duration runs 2-3 hours at moderate doses. The caryophyllene secondary terpene adds a distinct layer: a grounding warmth that prevents the experience from feeling unanchored.

Terpene Breakdown

Primary: Myrcene Β· Secondary: Caryophyllene Β· Tertiary: Linalool. 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 myrcene dominance anchors the aroma, caryophyllene provides mid-range character, and linalool contributes a subtle background note that distinguishes this strain from others sharing the same primary terpene.

Suitability and Recommendations

Who grows Supergirl 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.
