How to Grow Cinderella 99
Cinderella 99 is a classic, uplifting sativa famous for its sweet, fruity flavor and easy grow. It is an 80/20 sativa-dominant feminized plant with a balanced, medium 13-17% THC, a berry, fruity, sweet and tropical flavor, and a creative, focused and munchie-inducing effect. Compact for a sativa at around 1 m but a strong yielder, it is a rewarding, beginner-friendly way to grow a lively daytime strain.
This is a feminized, photoperiod strain, so every seed grows into a flowering female and you never have to identify the sex or remove males. It flowers in response to the light cycle rather than on a timer, so indoors you switch it to 12/12 to start flowering once it has reached the size you want, and outdoors it finishes around October. Its lively, fruity character comes from a Jack Herer and Shiva Skunk heritage, a cross that balances sativa energy with manageable size.

Growing a Feminized Strain
Cinderella 99 is a feminized, photoperiod plant, so it flowers in response to the light cycle rather than on a timer. Indoors you grow it under long days of around 18 hours of light while it builds size, then switch to a 12/12 cycle to trigger flowering once it has reached the height and shape you want. Outdoors it follows the seasons and flowers as the days shorten, finishing around October. Because the seeds are feminized, every plant grows into a flowering female, so there is no sexing and no need to remove males.
Being photoperiod, it gives you full control over the vegetative stage: veg it longer for a bigger plant or flip it early to keep it compact. Unusually for an 80% sativa, it stays short at around 1 m, which makes it much easier to manage than most sativas and a good fit for smaller spaces. Give it a little low-stress training during veg to open the canopy, and it builds resinous, fruity buds with the lively character its Jack Herer side is known for.
Climate and Where to Grow It
Cinderella 99 suits a warm, tropical or Mediterranean-style climate with plenty of sun, steady warmth and good airflow. Outdoors it finishes around October, so it suits regions where the early autumn stays dry and mild enough for its buds to ripen cleanly. Its compact size also makes it a practical choice where space or height is limited.
It performs well both indoors and out. Indoors it returns a strong 500 g/m² in a well-managed tent, which is excellent for such a compact sativa, while outdoors it gives around 400 g per plant with full sun and room for the roots. As a short, skunk-influenced sativa of around 1 m it is easy to manage, so the main job is keeping the canopy open so light and air reach the lower buds.
Keep humidity under control through flowering to protect the resinous buds: around 55-60% early on, nearer 40-45% as the flowers fill out, and lower toward harvest. Its moderately dense, sativa-leaning buds benefit from steady airflow, so keep the air moving and humidity sensible to keep the finish clean. Aim for daytime temperatures around 72-82°F (22-28°C), which this warm-climate plant enjoys.
Feeding Schedule (EC Guide)
Cinderella 99 is a moderate feeder that responds well to a steady, measured feeding schedule. Build nutrients up gradually through the vegetative stage, then shift toward bloom nutrients once it flips to flower and the buds begin to swell. Taper off for the final flush so the sweet, fruity flavor comes through clean and the smoke finishes smooth. The ranges below are a starting guide; adjust to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed while roots establish |
| Vegetative | 0.8-1.2 | Raise nitrogen as the plant builds size |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Indoors, Cinderella 99 flowers in about 8 to 10 weeks once you switch it to a 12/12 light cycle, while outdoors it ripens around October as the days shorten. It fills out with resinous, fruity-smelling buds on a compact, sativa-leaning frame, keeping the lively structure of its Jack Herer parent without the usual sativa stretch. As a mostly sativa plant it still finishes in a reasonable window, which makes timing the harvest straightforward.
Yields are strong for a compact plant: around 500 g/m² indoors and 400 g per plant outdoors with good sun and space. Give it light training so the lower buds get light, feed it steadily through its cycle, and harvest when most of the trichomes have turned cloudy for the fullest sweet, fruity flavor and a lively, creative effect.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry is worthwhile with such a fruity strain, because a gentle dry protects the sweet, tropical aroma and the trichomes that carry its flavor.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings out the berry, fruity, sweet and tropical notes and smooths the smoke, which matters on a strain like Cinderella 99 where that bright, sweet character is the main attraction.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Cinderella 99 is a resinous, aromatic plant, so its trim works well for dry sift, bubble hash or rosin. It makes for a flavorful, sweet-and-fruity concentrate run from material most growers would otherwise throw away, keeping that bright Cin99 character in a lighter everyday extract.
Flavor and Terpenes
Cinderella 99 has a bright, sweet flavor: ripe berry and fruit with a sweet, tropical lift, the kind of full, juicy fruitiness that made it a classic. It is a smooth, sweet-and-fruity smoke, and a good cure really brings that character forward in the jar and on the inhale.
Its terpene profile shapes that character. Terpinolene drives the fresh, fruity and slightly tropical lift that defines Cin99, while myrcene lays down a ripe, fruity base. Caryophyllene adds a gentle, peppery spice, and alpha-pinene brings a fresh, piney edge, with terpineol rounding it out with a soft, herbal-floral note. Together these terpenes frame the berry, fruity, sweet and tropical character Cinderella 99 is known for.
Effects and Best Use
With its balanced, medium 13-17% THC and sativa-dominant 80/20 make-up, Cinderella 99 delivers a bright, clear-headed experience. It is reported as creative, focused and munchie-inducing, pairing an upbeat, inspired head with a tendency to leave you reaching for a snack, so it leans to daytime and active use. Its moderate potency keeps it very approachable and easy to dose.
That creative, focused and munchie-inducing profile makes it a good daytime strain, suited to staying active, creative and sociable while enjoying its sweet, fruity flavor. The combination of a compact, high-yielding grow, a gentle effect and a classic sweet profile is exactly why it has stayed popular for so long.
Common Problems and Pro Tips
The main thing that makes Cinderella 99 easy is its compact size: unlike most sativas it stays short at around 1 m, so it rarely needs aggressive height control. Still, keep the air moving, hold humidity down as the buds fill out, and defoliate a few of the largest fan leaves in mid-flower so light and air reach the lower buds. A tidy canopy keeps the whole plant ripening evenly.
Because it is photoperiod, you can decide its final size: veg it longer for a bigger plant or flip early to keep it even more compact, and give it low-stress training during veg to spread the canopy. Its short, even structure makes a multi-plant run simple, since the plants grow at a similar pace and there are no males to remove.
As a pro tip, feed it steadily rather than hard: it is a moderate feeder, so build nutrients up gradually and ease off into a plain-water flush for the last week or two to keep the sweet, fruity flavor clean. Harvest when most trichomes are cloudy, and give it a full three to four week cure to round out its bright aroma.
