Lineage: Cinderella Jack Auto traces back to Seedsman's own Cinderella Jack cut, pushing sativa-dominant traits into an autoflowering format that doesn't require a light schedule change to trigger bloom. The THC range runs 18–25%, which puts the upper end firmly in heavy-hitting territory for an auto — not just a casual afternoon smoke.

Indoors, growers are pulling 400–550g/m² across the 9–11 week seed-to-harvest window, which is a solid return for a strain rated easy to grow. The flavor profile leans into pine and earth rather than anything sweet or fruity, so expect a clean, resinous nose in the dry room. It works in both indoor and outdoor setups, making it flexible for small-space tent growers and backyard runs alike.

Good pick for newer growers who want a fast, high-THC sativa without the complexity of managing photoperiod timing.

THC Level & Potency

Cinderella Jack Auto delivers THC levels of 18-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies.

Growing Cinderella Jack Auto

Cinderella Jack Auto is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 9-11 weeks total with yields of 400-550g/m². Plants typically reach 60-120cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Cinderella Jack Auto features a pine, earthy terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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 Jack Auto is commonly reported to help with depression, fatigue, lack of motivation, and ADHD symptoms. The uplifting, focusing effects make it popular among medical users seeking daytime functionality. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
