Spec sheet first — strain: sativa, seed type: feminized, THC: 40-50%, yield band: medium, environment: indoor or outdoor.

Premium Cultivars lists this at $31.50 — above the median of $25.98 across 20 listings. Pack options: 3-seed at $31.50, 5-seed at $37.50, plus larger sizes.

The lab panel on this one stops people mid-scroll — 40–50% THC is a number most growers treat with healthy skepticism until they run it themselves. Cinderella 99 has been earning that figure since the 1990s, tracing back through Jack Herer and Shiva Skunk to produce a sativa-leaning plant that finishes in 9–11 weeks, which is notably quick for something this potent. Indoors or out, expect 400–500g/m² when conditions are dialed in. The smoke profile leans fruity and sweet upfront, with a skunky edge that kicks in on the exhale — not a one-note experience.

Difficulty sits at moderate, meaning you'll want some environmental control and feeding experience, but you don't need to be a seasoned pro to pull a solid harvest. Growers chasing a fast-finishing, high-THC sativa for daytime creative use will find this one worth the attention it demands.

Effects & Experience

With THC levels reaching 50%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Cinderella 99 delivers THC levels of 40-50%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Cinderella 99

Cinderella 99 is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 9-11 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Cinderella 99 features a fruity, skunky, sweet, floral terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Cinderella 99 is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
