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 2026-04-15 on 500 seeds.

Germination rate: 98.8% (n=500)
Last QC test date: 2026-04-15
Indoor yield: 465-630 g/m² (avg across 13 verified grower reports)
Outdoor yield: 621-902 g/plant (avg across 4 verified grower reports)

About Hyper Critical Auto

Days 1 to 14, seed to fourth node: Expect Hyper Critical to crack in roughly 48 hours on damp paper towel and to break soil by day three. Early growth comes in low and wide — broad seed leaves first, then the dark fan leaves the indica side is known for. Four nodes by the end of week two, stacked close together. Damping off is rare if you hold near 70% humidity through this stage.

Weeks 3 to 6, building the frame: Top at the fourth node and the laterals take over fast. A 60 x 60 cm footprint filled by week five is normal, still under 40 cm tall, which is what makes this workable in a small tent.

Bloom, weeks 1 to 79: The 68/32 character becomes obvious here. Linalool usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: 325–425 g/m². Height: 70–110 cm. Tested at 18% 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. Density climbs almost daily — by week five a developing cola should feel firm rather than springy under light pressure. Pull the fan leaves shading the lower canopy at the start of week four, which matters more than usual if the room is sitting near 55% humidity through a damp autumn.

Weeks 77 to 79, ripening. Drop to plain water for the final ten days. The linalool 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 325–425 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 7–9 weeks from seed. Stands 70–110 cm. Indoors it returns 325–425 g/m². Outdoors, 400–500 g/plant a plant. Regular seeds with autoflowering genetics.

What Hyper Critical Is Like to Use

The effects most commonly reported for this cultivar are euphoric, creative, calm. At 18% THC it sits in a bracket where the dose does most of the work. A single bowl vaporised at 185°C gives a manageable body relaxation with your head still intact — enough to close out a long day in the summer heat. Push the dose and it moves decisively toward physical sedation, which is how it tends to end up as a winter evening cultivar. The Linalool/Myrcene pairing leaves a shifting profile that keeps turning up new notes on the palate.

Where it fits: quiet evenings, a film, recovery after exercise, and the hours before sleep.

The Aromatic Three

Leading with Linalool, then Myrcene, and Caryophyllene underneath. This trio turns up repeatedly in cultivars that win things, and it is why a jar of Hyper Critical tends to get a reaction the first time it is opened after curing. Linalool sets the anchor, myrcene fills the middle, and caryophyllene sits in the background doing the work that separates this from every other strain built on the same primary terpene.

Suitability and Recommendations

Hyper Critical 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. Because it autoflowers there is no light cycle to manage at all, which is what makes it work on a balcony, in an out-of-the-way outdoor spot, or anywhere a timer would be one more thing to go wrong. A September-to-May outdoor season comfortably covers a 7–9 weeks from seed bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.
