About Pop Rox Auto
Days 1-14, germination and early veg. Pop Rox generally cracks within about two days on damp kitchen paper and is above the medium by day three. The first fortnight came in even, without either racing or stalling. Four solid nodes by day 14 and the spacing that suggests the frame it will build. Keep the humidity near 70% and damping off stops being a concern.
Weeks 3-6, veg. A top at node four and a few ties produced six even leaders and a flat canopy across a 70cm square by the time it was flipped.
Bloom, weeks 1-9. The 42/58 character came through clearly. Caryophyllene was noticeable by week three and kept building; resin was obvious without a loupe from about week five. Indoor yield: up to 350 g/m2. Height: Short. Tested at 20%. Rated intermediate.
The rest of the run
Weeks 4-6, mid-bloom. Loose clusters from week three closed up into defined colas. Development stayed even across the canopy, which is what the veg training was for: eight comparable colas instead of one dominant top and a set of stragglers.
Ripening, weeks 7-9. Plain water for the last ten days. Caryophyllene was strong enough by then that carbon filtration was not optional in a terraced house. Heads went clear to milky over the final fortnight, amber showing on sugar leaves first, and around 15% amber on the calyxes is a defensible place to stop.
Drying and curing. Hung whole in the dark at 17ยฐC and 58% humidity for twelve days, both held by a dehumidifier because an October room here will hold neither. Stems snapped instead of bending, which is the only test worth trusting. Four weeks in glass after that. The up to 350 g/m2 figure held up. Limonene was far more present after the cure than at harvest โ the cure makes flavour, it does not merely preserve it.
Flowering: 50-60 days. Indoor yield: up to 350 g/m2. Outdoor yield: up to 350 g/plant. Plant height: Short. Rated intermediate difficulty. Regular seeds, autoflowering.
Flavour, aroma and effect
Pop Rox arrives in order. The first draw at 20% THC gives peppercorn heat that lands at the back of the throat. The euphoric, calm character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Limonene underneath contributes a lift that stops it going heavy.
Terpene breakdown
Primary: Caryophyllene ยท Secondary: Limonene ยท Tertiary: Myrcene. This is a combination that turns up repeatedly in cultivars people rate, and it is usually what gets commented on when a jar is opened for the first time after a proper cure. Caryophyllene anchors it, limonene holds the middle, and myrcene sits behind both โ the last of those being what separates this from other strains leading on the same terpene.
Who it suits
Who does well with Pop Rox? Back-garden and balcony growers in Dublin, Cork and Galway. Anyone who wants a crop dry and put away before the autumn closes in. Indoor growers short of headroom. The autoflowering genetics run to their own clock, so there is no schedule to manage and no anxiety about light leaks. Rated intermediate, which means a moderate learning curve that rewards attention without needing specialist kit.

Pop Rox Auto โ Breeder Information
Royal King GeneticsBred and stabilised in-house by Royal King Genetics โ our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read the full breeding process and about page.
Pop Rox is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the pack-to-pack uniformity the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.
Lock the autoflower trait in Pop Rox through five generations of selection.
Chosen for trichome density, bud structure and the hybrid trait balance the cross was engineered for.
