About A-10 Feminised

Days 1-14, germination and early veg. A-10 generally cracks within about two days on damp kitchen paper and is above the medium by day three. The first fortnight came in low and thickset, wide seed leaves followed by the broad dark fans this side of the genetics gives. Four nodes by day 14, the gaps between them already short. Keep the humidity near 70% and damping off stops being a concern.

Weeks 3-6, veg. Branching filled out fast after a single top at node four, holding a 60cm square and staying under 40cm — which is what makes this shape practical in the small tents most people actually have room for.

Bloom, weeks 1-9. The 70/20 character came through clearly. Myrcene was noticeable by week three and kept building; resin was obvious without a loupe from about week five. Indoor yield: up to 400 g/m2. Height: Short. Tested at 18-22%. Rated intermediate.

The rest of the run

Weeks 4-6, mid-bloom. Loose clusters from week three closed up into defined colas. Density climbed daily until a bud squeezed like a firm ball by week five. Fan leaves came off at the start of week four to keep air under the canopy, which mattered — an Irish autumn room sits damp, and flower this tight does not tolerate still air.

Ripening, weeks 7-9. Plain water for the last ten days. Myrcene 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 17°C 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 400 g/m2 figure held up. Caryophyllene was far more present after the cure than at harvest — the cure makes flavour, it does not merely preserve it.

Flowering: 50-60 days. Indoor yield: up to 400 g/m2. Outdoor yield: up to 450 g/plant. Plant height: Short. Rated intermediate difficulty. Feminised seeds.

Flavour, aroma and effect

A-10 arrives in order. The first draw at 18-22% THC gives earth and musk, coating rather than sharp. The creative, relaxed, happy character follows in minutes, as weight behind the eyes that works down through the shoulders. By a quarter of an hour it reads as physical stillness rather than sedation — a strong disinclination to stand up. Two to three hours at a sensible dose. Caryophyllene underneath contributes warmth that keeps it anchored.

Terpene breakdown

Primary: Myrcene · Secondary: Caryophyllene · Tertiary: Linalool. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps caryophyllene and linalool audible over the myrcene; run it hotter, or burn it, and all three collapse into one note that is pleasant enough and tells you nothing.

Who it suits

Who does well with A-10? Indoor growers who want to choose their own timeline. Tunnel growers who want to decide when flowering starts rather than letting August decide it. Anyone with the space to veg it properly first. Rated intermediate, which means a moderate learning curve that rewards attention without needing specialist kit.

A-10 Feminised — Breeder Information

Royal King Genetics

Bred and stabilised in-house by Royal King Genetics — 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.

Breeding Programme
Backcross Stabilisation (BX2) — modern hybrid fixing
Stabilisation Notes — What This Means for Your Grow

A-10 carries clone-derived parents from the modern hybrid. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and compact internode spacing run uniform across the population.

Breeding Goal

Pin the compact internode spacing that came out of the original A-10 cross.

Selection Focus

Chosen for resin density, indica-leaning frame and tight internodes that suit indoor production.

Pollen / Mother Source

Royal King Genetics in-house mother stock — pollen taken from a sibling male drawn from the same selected pheno population.
