About Cinex Auto

Read Cinex backwards from the harvest: up to 450 g/m2 under lights, up to 350 g/plant outdoors, with resin filling out towards 20% THC. Weight goes on evenly across the 50-60 days seed to harvest of bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 30/60 split gives you calyx density and an even spread of resin rather than one at the cost of the other. Outdoors, late September to mid-October is the window that misses the wettest of the finish across most of the country while still letting the caryophyllene arrive.

Getting the weight out of this plant

Three stretches of the 50-60 days seed to harvest of bloom decide whether you reach the top of this strain's range (up to 450 g/m2 indoors, up to 350 g/plant outdoors). The rest is maintenance.

The first ten days of flower. What the plant does during the stretch sets canopy height, and canopy height sets how evenly the light lands. Somewhere around a third is typical. One pass of low-stress training over the tallest shoots keeps the top flat.

Weeks three to five. Caryophyllene production climbs through here, and it responds to a day-night temperature gap of 6-8°C. British autumn nights hand that to outdoor growers for free from September; indoors you have to build it, at roughly 25-26°C lights-on and 18-20°C lights-off. Bloom feed goes potassium-heavy around EC 1.6-1.8.

The last ten to fourteen days. Stop feeding and run pH-corrected water. Check trichomes daily under a 60x loupe — cut at 10-15% amber for the middle of the range. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Flowering: 50-60 days seed to harvest. Indoor yield: up to 450 g/m2. Outdoor yield: up to 350 g/plant. Rated intermediate difficulty.

Flavour, aroma and effect

Cinex arrives in stages. The first draw at 20% THC brings dry pepper that registers at the back of the throat. The energetic, euphoric, uplifted character follows within minutes, as a head and body effect at once. The mind stays clear while the muscles let go by degrees, which is what makes it adaptable — a small dose carries an afternoon, a larger one turns into an evening. The limonene underneath adds a lift that stops it turning heavy.

Terpene breakdown

Primary: Caryophyllene · Secondary: Limonene · Tertiary: Myrcene. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with caryophyllene; after three or four weeks sealed in glass at 16-18°C the myrcene underneath comes up and the whole thing gains a layer. Vaporising between 180°C and 195°C catches the widest span of them, since the lighter myrcene molecules are the first thing heat destroys.

Who it suits

Who does well with Cinex? Balcony growers in flats from Brighton to Glasgow. Anyone wanting one quick outdoor crop rather than a long project. Indoor growers short of headroom. The autoflowering genetics run on their own clock, so there is no light schedule to manage, no anxiety about light leaks, and harvest comes 10-12 weeks from germination whatever the season is doing. Difficulty is rated intermediate, which means a moderate learning curve that rewards attention without demanding a laboratory.

Cinex Auto — 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.

F5
Generations
5+
Breeding Programme
Autoflower Programme — five-generation auto trait fixing
Stabilisation Notes — What This Means for Your Grow

Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. Cinex sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.

Breeding Goal

Lock the autoflower trait in Cinex through five generations of selection.

Selection Focus

Chosen for terpene profile, vigour, structure and finish-time consistency.

Pollen / Mother Source

Royal King Genetics in-house breeder room — pollen taken from a generation-tracked sibling-male line.
