About Cinex Auto

Here is what Cinex delivers at harvest: up to 450 g/m2 per square metre indoors, up to 350 g/plant per plant outdoors in UK conditions, with resin production peaking at 20% THC. Those numbers tell a story when you work backwards through the 50-60 days seed to harvest window. Weight distribution across the 50-60 days seed to harvest cycle is pleasingly even, with a noticeable surge in the closing two weeks that rewards growers who resist harvesting prematurely. The 30/60 balance means you get both calyx stacking density and respectable trichome spread. For outdoor UK customers, the ideal harvest window lands between late September and mid-October — early enough to dodge the wet autumn finish in most regions, late enough to capture the full caryophyllene terpene development.

Maximising Your Harvest

To reach the upper end of this strain's yield potential (up to 450 g/m2 indoors, up to 350 g/plant outdoors), focus your efforts on three critical windows during the 50-60 days seed to harvest period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Moderate 30-40% stretch is typical. One round of low-stress training on the tallest shoots keeps everything level.

Window 2: Weeks 3-5 of bloom. Caryophyllene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8°C to encourage terpene accumulation — UK autumn evenings (September-October) naturally provide this swing for outdoor growers. Indoor cultivators should target 25-26°C during lights-on and 18-20°C during lights-off. Supplement with potassium-heavy bloom nutrients at EC 1.6-1.8.

Window 3: Final 10-14 days before harvest. Cease all nutrient input and flush with pH-adjusted water. Monitor trichomes daily with a 60x jeweller's loupe — harvest at 10-15% amber for a balanced effect. UK outdoor growers: this window typically falls from late September through mid-October.

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 Experience

The sensory arc of Cinex unfolds in stages. Initial inhalation at 20% THC brings a warm peppery spice that tingles at the back of the throat. The energetic, euphoric, uplifted effects emerge within minutes, presenting as a simultaneous head-and-body experience. Mental clarity remains intact whilst the muscles release tension progressively. This dual action makes it adaptable — a lighter dose suits afternoon tasks, a heavier dose transitions seamlessly into evening relaxation. The limonene secondary terpene adds a distinct layer: a mood-elevating brightness that counterbalances any heaviness.

Terpene Breakdown

Primary: Caryophyllene · Secondary: Limonene · Tertiary: Myrcene. Together these three compounds construct an aromatic signature that evolves throughout the curing process. Freshly dried flower leads with caryophyllene presence, but after three to four weeks in sealed glass jars at 16-18°C, the myrcene undertone strengthens and the overall bouquet develops a layered complexity. Vaporisation between 180°C and 195°C captures the broadest spectrum of these terpenes — higher temperatures degrade the more volatile myrcene molecules first.

Suitability and Recommendations

Who grows Cinex successfully? Balcony growers in flats from Brighton to Glasgow. Regional cultivators wanting a quick-turnaround outdoor crop. Indoor growers with limited headroom in small tents. The autoflowering genetics run on their own internal clock — no light schedule adjustments, no stress about light leaks, and harvest arrives 10-12 weeks after germination regardless of the season. Difficulty is rated intermediate, meaning a moderate learning curve that rewards attention without demanding laboratory-grade conditions. Delivered UK-wide in discreet, unbranded packaging with germination guarantee included.

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.
