By backcrossing Princess with Shiva Skunk, Mr. Soul created a strain that not only boasted rapid flowering but also retained the powerful effects and aromatic qualities of its parents.
The lineage of Cinderella 99 is a testament to careful breeding. The combination of Jack Herer and Shiva Skunk results in a sativa-dominant hybrid that is both potent and flavorful. The strain’s genetic makeup contributes to its fast flowering time, making it a favorite among cultivators aiming for quick harvests without sacrificing quality.
Effects and Characteristics
Cinderella 99 is renowned for its uplifting and energetic effects, making it a go-to choice for those seeking a creative and euphoric high. Its THC content ranges from 18% to 22%, delivering a potent experience that can invigorate the mind and body.

Growing Cinderella 99 Indoors vs Outdoors
Environmental Requirements
To cultivate Cinderella 99 successfully, maintaining the right environmental conditions is crucial. Indoors, temperatures should range between 70-85°F (21-29°C) during the day, with slightly cooler nights. Humidity levels must be kept stable to prevent mold, ideally between 40-50% during flowering. Adequate lighting, such as high-quality LED or HPS lamps, is essential for robust growth.
For outdoor cultivation, Cinderella 99 thrives in warm, sunny climates. Ensure the chosen location receives ample sunlight and has well-draining soil. In cooler regions, using a greenhouse can extend the growing season and protect plants from adverse weather. Outdoor growers should aim for a harvest between late September and early October.
Common Cultivation Challenges
While Cinderella 99 is generally resilient, growers may encounter challenges such as nutrient imbalances or pest infestations. Regular monitoring of pH levels, ideally between 6.0-6.5, and nutrient concentrations can prevent deficiencies and toxicities. Using organic pest control methods, such as neem oil or introducing beneficial insects, can help manage pests without harming the plants.
Another common issue is odor control, especially during the flowering phase. Installing carbon filters or using odor-neutralizing agents can mitigate the strong aroma. Ensuring proper airflow and ventilation in the grow space is crucial to prevent mold and mildew, which thrive in stagnant, humid environments.
Advanced Techniques for Maximizing Yield
For those aiming to maximize their Cinderella 99 yields, employing advanced cultivation techniques can be beneficial. Techniques such as the Screen of Green (ScrOG) or the Sea of Green (SOG) can optimize light exposure and canopy management, leading to higher yields. These methods involve training plants to grow horizontally, ensuring even light distribution and promoting bud development.
Additionally, implementing a CO2 enrichment system can enhance photosynthesis and accelerate growth. By increasing CO2 levels to around 1200-1500 ppm during the vegetative stage, plants can experience faster growth rates and potentially higher yields. However, it’s crucial to monitor environmental conditions closely to avoid stressing the plants.

Professional Tips for Growing Cinderella 99
- Maintain 70-85°F (21-29°C) during the day to optimize growth. Temperatures outside this range can stress plants, reducing yield and potency.
- Use a light cycle of 18/6 during vegetative growth. Switching to 12/12 initiates flowering, crucial for timely harvests.
- Ensure pH levels remain between 6.0-6.5 for nutrient absorption. Deviations can cause deficiencies or toxicities, impacting plant health.
- Keep humidity at 40-50% during flowering to prevent mold. High humidity can lead to bud rot, destroying crops.
- Install carbon filters to manage strong odors during flowering. Neglecting odor control can attract unwanted attention.
- Monitor for pests weekly. Early detection of issues like spider mites prevents infestations from escalating.
