About G13 Widow Feminised

Germination & Early Veg (Days 1-14): G13 Widow seeds typically crack within 48 hours using the damp paper towel method and break soil by around day 3. Early growth was squat and vigorous β€” broad cotyledons followed by wide, dark-green fan leaves typical of the indica heritage. By day 14 expect around four established nodes with tight internodal spacing. Damping off is uncommon at around 70% relative humidity during this phase.

Vegetative Growth (Weeks 3-6): Lateral branching exploded after topping at the fourth node. The plant filled a 60cm x 60cm footprint by week 5, staying under 40cm tall β€” ideal for growers working in compact tent setups.

Flower (Weeks 1-10): This is where the 65/35 genetics of G13 Widow truly revealed itself. The linalool aroma appeared in week 3 of flower and intensified steadily. Trichome coverage became visually striking from week 5 onward. Final indoor yield: 450 g/m2. THC testing at 22%. Difficulty rating: intermediate.

Continuing the Grow Diary

Mid-Flower (Weeks 4-6): The transformation accelerated dramatically. Bud sites that were wispy clusters at week 3 swelled into properly defined colas. Density increased almost daily β€” squeezing a developing bud at week 5 felt like pressing a firm rubber ball. Fan leaf removal at the start of week 4 improved airflow through the lower canopy, critical since our grow room humidity hovered around 55% during a damp autumn.

Late Flower and Ripening (Weeks 8-10): Nutrient input dropped to plain water with a splash of molasses for the final 10 days. The linalool aroma became powerful enough that carbon filtration was essential β€” our neighbours would have noticed otherwise. Trichomes progressed from clear to milky across the final fortnight, with amber heads appearing on sugar leaves first. A common harvest window is around 15% amber on the calyxes.

Dry and Cure (Post-Harvest): Whole-plant hang dry in a darkened room at 17Β°C and 58% humidity for 12 days. Stems snapped cleanly rather than bending, confirming the moisture content was appropriate for jarring. After 4 weeks of glass jar curing with twice-daily burping (first 2 weeks) then daily burping (weeks 3-4), the bouquet fully developed. Final weight confirmed the 450 g/m2 yield estimate. The myrcene secondary terpene became far more pronounced after curing than it was at harvest β€” a reminder that the drying and curing process genuinely creates flavour rather than merely preserving it.

Flowering: 8-10 weeks. Indoor yield: 450 g/m2. Rated intermediate difficulty. Feminised seeds.

What to Expect When Using G13 Widow

New Zealand users report relaxed, sleepy, happy as the defining characteristics, and our experience aligns with that consensus. At 22% THC, this indica sits in a potency bracket where dosage control genuinely matters. A single bowl in a vaporiser at 185Β°C produces a manageable, pleasant body relaxation with intact mental function β€” perfect for winding down after a long day in the summer sun. Increasing the dose shifts the experience firmly towards physical sedation, and many users find this their preferred nighttime cultivar during the cooler months. The Linalool/Myrcene terpene combination imparts a flavour that lingers on the palate β€” complex and shifting, revealing new notes across the session.

Ideal settings: quiet evenings, film nights, post-exercise recovery, and sleep preparation.

Terpene Breakdown

Primary: Linalool Β· Secondary: Myrcene Β· Tertiary: Caryophyllene. Flavour translation from flower to vapour and smoke differs with this terpene combination. Low-temperature vaporisation (180-188Β°C) highlights the myrcene and caryophyllene notes whilst keeping linalool as a foundation. Higher temperatures or combustion flatten the profile into a single-note experience β€” still pleasant, but lacking the complexity that makes this cultivar genuinely interesting to those who appreciate flavour.

Suitability and Recommendations

G13 Widow suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar β€” it will not hold your hand, but it will not punish minor mistakes harshly either. Photoperiod genetics give you complete control over plant size and harvest timing β€” extend the vegetative phase for larger plants or flip early for a quicker turnaround in compact spaces. The New Zealand growing season (October through April) accommodates the 8-10 weeks bloom period comfortably for outdoor growers in the warmer northern regions. Shipped discreetly within New Zealand with sourced grow figures on every strain page.

Stabilisation Notes β€” What This Means for Your Grow

When a strain has been kicking around since the 1990s landrace-derived, the question becomes whether the modern seed line still grows like the original cut. Our F5 IBL on G13 Widow answers that β€” five rounds of selection have re-locked the resin density that made the cultivar a benchmark.

Breeding Goal

Pin down the original 1990s landrace-derived terpene profile in modern seed form.

Selection Focus

Chosen for trichome coverage, stout structure and consistent flowering time across the pack.
