Quick read: 18-25% THC, 60-120cm mature height, 9-11 weeks total bloom. Genetics: Cinderella Jack (Seedsman genetics). Difficulty: easy.

Lineage: Cinderella Jack traces back to Seedsman's own breeding program, crossing sativa-dominant stock selected for both resin production and a clean pine-forward nose. That heritage shows up in the numbers — growers are pulling 400–550 g/m² in as little as 9–11 weeks from seed, with THC testing between 18–25% depending on environment and finishing conditions.

The flavor profile stays in pine and earthy territory, which suits indoor setups where terpene preservation is easier to manage. Because it's an autoflower, light schedule flexibility makes it a practical option for Canadian growers dealing with shorter outdoor seasons or supplemental lighting indoors. Difficulty is rated easy, so it doesn't punish minor feeding errors or humidity swings the way some high-THC sativas can. CBD sits below 1%, so expect a clear, head-focused effect rather than anything sedating.

Best suited to growers who want a high-THC sativa-leaning auto without babysitting a photoperiod through a Manitoba or Ontario shoulder season.

THC Level & Potency

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.
