Cinderella 99 (C99) Cannabis Strain Review: Effects, Flavor, and Growing Tips

Cinderella 99, commonly known as C99 or Cindy 99, is a sativa-dominant hybrid cannabis strain celebrated for its potent cerebral effects, sweet fruity flavors, and efficient growth characteristics. Developed by Mr. Soul of Brothers Grimm, the C99 strain has garnered a dedicated following among both recreational users and cultivators. ​

Genetics and Lineage

Cinderella 99, often affectionately called “C99” or “Cindy,” has a fascinating and somewhat serendipitous origin. Its story begins in the late 1990s when the breeder known as “Mr. Soul” from Brothers Grimm Seeds discovered a few seeds in a Sensi Seeds 2-gram package of Jack Herer purchased from a coffee shop in Amsterdam. Intrigued by the exceptional quality of the buds, he germinated the seeds and began a meticulous breeding project.
Through a careful process of backcrossing and phenotype selection over several generations, Mr. Soul stabilized a line that consistently expressed the traits he admired—short flowering time, manageable height, dense buds, and a sweet, fruity aroma. One standout female phenotype, nicknamed “Princess,” became the cornerstone of the Cinderella 99 project.
Cinderella 99’s final genetic lineage is commonly cited as Jack Herer crossed with Shiva Skunk, blending the uplifting cerebral high of Jack Herer with the hardiness and resin production of Shiva Skunk. The resulting strain is 85% sativa and 15% indica, making it well-known for its energetic, euphoric effects and high THC content.
C99 is particularly renowned for its ability to deliver sativa-like effects with an impressively fast flowering time (usually 7–9 weeks), which is rare for sativa-dominant strains. This makes it a favorite among both indoor growers and those seeking a potent, creative, and clear-headed high without the long wait.

Aroma and Flavor Profile

Cinderella 99 is celebrated not just for its potent effects, but also for its captivating aroma and flavor that appeal to both novice and seasoned consumers. The strain boasts a vibrant terpene profile dominated by myrcene, limonene, and caryophyllene, which contribute to its distinctive scent and taste.
Its aroma is often described as a sweet, tropical bouquet bursting with notes of pineapple, mango, papaya, and citrus zest. These fruity overtones are balanced by subtle earthy and herbal hints, sometimes with a whisper of spice or skunk from its Shiva Skunk lineage.
When consumed, C99 delivers a smooth, flavorful smoke or vapor that mirrors its scent. The flavor profile combines juicy tropical fruitiness with tangy citrus and a touch of pine and spice, creating a refreshing and memorable palate experience. Some users also report a slight floral or vanilla-like sweetness on the exhale, adding to its complexity.
This sensory richness makes C99 not only a favorite for recreational enjoyment but also a go-to for cannabis connoisseurs who appreciate nuanced flavor and aroma in their strains.

Effects and Usage

The effects of Cinderella 99 are predominantly cerebral and energizing. Users often experience an uplifting and euphoric high that enhances creativity and focus, making it suitable for daytime use. The strain’s potency is notable, with THC levels ranging between 16% and 22%. While many appreciate its stimulating effects, some users have reported potential side effects such as anxiety or paranoia, especially with higher doses. ​
Medically, C99 has been utilized to alleviate symptoms associated with stress, depression, and fatigue. Its uplifting properties can provide temporary relief from mood disorders, while its energizing effects may combat feelings of tiredness. However, as with all cannabis strains, individual experiences may vary, and it’s advisable to consult with a healthcare professional before using C99 for medicinal purposes. ​

Cultivation Information

Cinderella 99 is a top choice for both novice and experienced cultivators due to its grower-friendly characteristics, fast flowering time, and impressive yields. Developed with efficiency in mind, this sativa-dominant hybrid defies the typical long flowering period associated with many sativa strains, completing its cycle in just 7 to 9 weeks—a significant advantage for those looking to optimize production timelines.
One of C99’s standout traits is its compact stature. Despite being sativa-dominant (85% sativa / 15% indica), the plants grow relatively short and bushy, rarely exceeding 3.5 feet in height indoors. This makes them ideal for indoor grows, especially in tent or cabinet setups, where vertical space is limited. Its structure responds well to training techniques such as topping, low-stress training (LST), and ScrOG (Screen of Green), which can help maximize light penetration and yield.
Cinderella 99 produces dense, crystal-coated buds with a high flower-to-leaf ratio, reducing the effort required during trimming. The buds are often large and sticky with a thick coating of trichomes, reflecting the strain’s high resin production—another bonus for hash or concentrate makers.
In terms of yield, C99 is known to produce up to 1.5 to 2 ounces per square foot indoors, and more when grown in optimal outdoor conditions. While it thrives indoors due to its compact size and environmental control, it can also be grown outdoors in warm, Mediterranean-like climates where it finishes before the first frost.

Final Thoughts

Cinderella 99 stands out as a sativa-dominant hybrid that combines a rich genetic background with appealing sensory attributes and potent effects. Its sweet, fruity aroma and flavor, coupled with its energizing and euphoric high, have solidified its reputation among cannabis enthusiasts. Also, its favorable cultivation traits make it a preferred choice for growers aiming for quality and efficiency. As with any cannabis strain, individual experiences may vary, so it’s recommended to approach C99 with mindfulness to personal tolerance and preferences.​
Cinderella 99 continues to earn its place among favorites—whether you’re seeking an uplifting high or a productive grow. Consider this strain when evaluating your next cannabis choice.
