Royal King Genetics — Seed-Lot Testing

Figures below come from our own seed-lot testing rather than breeder marketing, taken from a single batch tested 2026-03-18 on 375 seeds.

Germination rate: 97.4% (n=375)
Last QC test date: 2026-03-18
Indoor yield: 421-572 g/m² (avg across 17 verified grower reports)
Outdoor yield: 667-1024 g/plant (avg across 4 verified grower reports)

About Red Widow Feminised

Days 1 to 14, seed to fourth node: Expect Red Widow to crack in roughly 48 hours on damp paper towel and to break soil by day three. Growth is even and unhurried — four solid nodes by day 14, spaced somewhere between the two parent types. Damping off is rare if you hold near 70% humidity through this stage.

Weeks 3 to 6, building the frame: One top at node four and a light tie-down is all it asks for. Six leaders and an even canopy across roughly 70 x 70 cm, then it is ready to flip.

Bloom, weeks 1 to 10: The 47/53 character becomes obvious here. Caryophyllene usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: 305-610 g/m² (~ 400 g/m²). Height: Medium (150-245 cm). Tested at 25% THC. Difficulty: easy.

Bloom Through to Jar

Weeks 4 to 6. This is where the plant stops looking like a frame and starts looking like a crop. Development stays even across the bud sites, and the canopy work done in veg pays off now — eight comparable colas rather than one dominant top over a set of also-rans. Trichomes should be visible without magnification from about week four.

Weeks 8 to 10, ripening. Drop to plain water for the final ten days. The caryophyllene carry gets strong enough that carbon filtration stops being optional in a residential street. Trichomes run clear to milky across the last fortnight, amber showing on sugar leaves before it reaches the calyxes; around 15% amber on the calyxes themselves is a common place to cut.

Drying and curing. Whole-plant hang in the dark at 17°C and 58% humidity for roughly 12 days — when stems snap instead of bending, it is ready for glass. Burp twice daily for the first fortnight, then once daily through weeks three and four. Finished weight should land near the 305-610 g/m² (~ 400 g/m²) estimate. The myrcene note comes through markedly stronger after curing than it did at harvest, which is the clearest evidence that a cure builds flavour rather than merely preserving it.

Difficulty: easy. In flower for 8-10 weeks. Stands Medium (150-245 cm). Indoors it returns 305-610 g/m² (~ 400 g/m²). Outdoors, 425-567 g/plant (~ 550 g/plant) a plant. Feminised seeds.

What Red Widow Is Like to Use

The effects most commonly reported for this cultivar are relaxed, happy, euphoric. At 25% THC it sits in a bracket where flexibility is the point. Lower doses read clear and functional in the morning, higher doses read relaxed in the evening. Because the 47/53 split is even, direction is set by how much you take rather than fixed by the genetics. The Caryophyllene/Myrcene pairing leaves a warm spice that dries slightly on the exhale on the palate.

Where it fits: most occasions, with the dose adjusted to whatever the situation asks for.

The Aromatic Three

Leading with Caryophyllene, then Myrcene, and Humulene underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, caryophyllene leads. After three or four weeks in sealed glass at 16-18°C the humulene undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile humulene molecules are the first thing you lose.

Suitability and Recommendations

Red Widow is a reasonable fit for growers with the basics already in place. Understand pH, know roughly what nutrient ratios do, and be able to hold a light cycle — it will not carry you, but it does not punish the occasional slip either. Photoperiod genetics leave size and timing in your hands — hold it in veg for a bigger plant, or flip early when headroom is the constraint. A September-to-May outdoor season comfortably covers a 8-10 weeks bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.

Royal King Genetics Backcross Line — BX2 modern hybrid stabilisation
Stabilisation Notes — What This Means for Your Grow

Red Widow carries clone-derived parents from the recent-era. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and pack-to-pack uniformity run uniform across the population.

Breeding Goal

Carry a clone-derived recent-era hybrid through to a stable seed pack.

Selection Focus

Chosen for trichome density, bud structure and the hybrid trait balance the cross was engineered for.

Pollen / Mother Source

Royal King Genetics breeding facility — pollen from internally selected sibling males of the recurrent parent.
