Cinex
Cinex, sometimes spelled Cinnex, is the cross of Cinderella 99 and Vortex first stabilized in the Pacific Northwest in the early 2010s, with Reservoir Seeds running the original seed-form release and breeders including Joey Weed preserving the Cinderella 99 working line that anchors the cross. The flavor leans sweet citrus and floral on the inhale with a faint earthy exhale, and plants finish in nine to ten weeks indoors with medium-density buds and a moderate trichome layer. The high is one of the sharpest cerebral lifts in the sativa-hybrid category — fast onset, clear-headed, and energetic for the first hour before settling into a mild body warmth. Cinex is widely recommended as a daytime productivity strain for users with low THC tolerance because the cerebral effect lands more on focus than on stimulation.

Terpene profile
The aromatic compounds below shape how Cinex smells, tastes, and ultimately feels in the body.
- dominant
Terpinolene
Piney and fruity — fresh, slightly floral, common in sativa-leaning cultivars.
- secondary
Limonene
Uplifting citrus — typically associated with mood elevation and stress relief.
- secondary
Ocimene
Sweet and herbal — light, tropical, with a decongestant character.
- minor
Pinene
Alert and pine-forward — associated with mental clarity and bronchodilation.

Lineage
Cinex traces to Cinderella 99 × Vortex. The cross sits in the C99 / Vortex family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for Cinex
These EC and NPK targets are starting points calibrated for the strain's Sativa lean and moderate difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 1.2-1.4 EC
- Early flower
- 1.3-1.5 EC, NPK 2-2-3
- Mid flower
- 1.6-1.8 EC, NPK 1-3-4
- Late flower
- 1.4-1.6 EC
- Final week
- Plain pH-balanced water for the last 7-10 days; light flush if you ran nutrients on the higher end.

What to expect through the grow cycle
Cinex is documented with a 10-week flower and a longer stretch phase typical of sativa-leaning hybrids. The visual below maps a documented 14-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Cinex concentrate the most observational notes on the stretch window. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for Cinex. Plants establish root structure, leaf canopy, and node count before flower triggering, with a moderate difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-8)
- Cinex is documented as having high stretch. Reports describe the plant roughly doubling in height during this phase as the sativa-leaning structure establishes its final flowering frame.
- Bud sites (weeks 9-10)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Cinexnote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 11-12)
- Flowers thicken and calyxes fatten through this phase. Documented Cinex runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 13)
- Trichomes transition from clear toward cloudy and amber. Reports for Cinex describe the Terpinolene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 14)
- Calyx swelling is documented as complete and the harvest window opens. Published Cinex runs end here, within the 9-10 week flowering range reported by the breeder.

Common questions about Cinex
What does the name Cinex mean?
It is a contraction of the two parent strains — Cinderella 99 and Vortex (sometimes written as Cinnex or CinEx). The naming convention is common in Pacific Northwest breeding circles.
Is Cinex related to Cinderella 99?
Yes — Cinderella 99 is one parent of the Cinex cross. The Cinderella 99 (C99) side contributes the sweet citrus-floral terpene profile and the fast cerebral high, while Vortex adds the structural vigor and yield bump.
