C-99 x Blueberry (fast) Feminized

C-99 x Blueberry (fast) feminized seeds combine two landmark sativa-leaning genetics into a fast-finishing hybrid that punches well above its compact flowering window. This strain delivers dense, trichome-heavy buds with a fruit-forward terpene profile and a clean, uplifting effect, all within approximately 45 days of flower indoors.

Genetics & Lineage

The cross brings together Cinderella 99 — a compact, fast-cycling sativa phenotype descended from Jack Herer and noted for its resin production and cerebral potency — with the Original Blueberry, DJ Short's indica-dominant classic built on Thai, Purple Thai, and Afghani landrace foundations. A fast-version modifier has been introduced into the Blueberry parent line, which shortens the flowering period without altering the core chemical or aromatic expression. The result sits broadly in the sativa-dominant hybrid category, inheriting C-99's structure and mental clarity alongside Blueberry's flavour depth and resin density.

Aroma, Flavour & Effects

The dominant terpenes are pinene and linalool, which together produce a profile that is both sharp and softly floral. On the nose, fresh blueberry and ripe berry fruit sit at the front, undercut by a crisp, forest-clean pine note that keeps the sweetness grounded. The aroma intensifies noticeably in the final two weeks of flower — at full ripeness it carries real presence. After curing, the flavour becomes rounder and more complex, with the berry notes deepening and a subtle lavender-like quality from the linalool emerging on the exhale.

Effects are sativa-forward: clear-headed, uplifting, and mentally active without tipping into anxiety. The Blueberry genetics add a physical ease that rounds out the experience without heaviness. Onset is relatively quick given the sativa dominance, and the duration holds steady for 2 to 3 hours at moderate doses.

Growing Profile

Indoors, flowering completes in approximately 45 days, making this one of the faster-finishing hybrids in its class. Expect significant vertical stretch during the transition to flower — plan for plants to increase in height by 50 to 80 percent from their pre-flower size. Despite this vigour, the buds form tightly and require minimal manicuring at harvest, which reduces post-harvest workload considerably. Yields are substantial for the flowering window, with well-managed indoor plants producing dense, resinous colas throughout the canopy. Outdoors, harvest typically falls in mid-September, ahead of most autumn weather risks. The fast version genetics make it particularly suitable for climates with shorter warm seasons. Low-stress training and screen-of-green setups are well suited to managing the stretch while maximising light penetration and overall output.

Difficulty sits at beginner-to-intermediate. The plant responds well to feeding, tolerates moderate humidity variation, and the abbreviated flowering time reduces the window for late-stage issues like mould or bud rot.

Who This Strain Is For

Growers who want a sativa-influenced effect without committing to a 70-plus-day flowering cycle will find this strain highly practical. It suits indoor cultivators working with vertical space constraints who can manage stretch through training, and outdoor growers in temperate regions who need a reliable mid-September finish. The terpene profile appeals to consumers who favour fruit-forward flavours with complexity rather than one-dimensional sweetness. Both first-time and experienced growers can run this strain confidently.

For a fast-finishing sativa hybrid with genuine flavour depth and consistent structure, this cross is a well-constructed option that delivers on its genetics.
