Appearance

Cinderella Jack typically develops medium-density flower clusters with a high calyx-to-leaf ratio, resulting in sculpted buds that are relatively easy to trim. The flowers are often a vibrant green, accented by amber pistils that deepen as the plant matures. Minimal sugar leaves are common on well-formed buds, which are heavily coated in trichomes, indicating substantial resin production.

The buds often appear glassy or sugared due to the dense trichome coverage, feeling noticeably sticky even before full maturity. Plant morphology generally remains compact to medium in height, even for an autoflower, with moderate internodal spacing that supports dense bud development throughout the canopy.

Aroma & Flavor

The aroma of Cinderella Jack is characterized by bright, coniferous notes, including distinct pine needles, crushed herbs, and citrus zest. Underlying these top notes are tropical fruit undertones, often reminiscent of pineapple and grapefruit, a likely contribution from its Cinderella 99 lineage. A subtle peppery warmth, attributed to beta-caryophyllene, adds a spicy complexity to the bouquet.

On the palate, the flavor profile begins with a clean pine taste, followed by grapefruit-citrus notes and a faint floral sweetness. The finish often presents an earthy, hash-like echo with a hint of clove or pepper, grounding the overall taste. Vaporized flower tends to highlight the citrus-pine clarity, while combustion can bring out more of the spicy and resinous forest characteristics.

Effects

Cinderella Jack delivers a fast-acting and potent cerebral experience, characterized by energetic and euphoric sensations. Its sativa-leaning genetics promote uplift and a sharpened mental focus, making it suitable for daytime use. The effects are often described as invigorating and mood-enhancing, providing a strong psychotropic experience due to its high THC content.

Terpenes & Cannabinoids

This strain is noted for its robust terpene profile, with total terpene content reported around 1.6% in some examples, which is considered significant for an autoflower. Dominant terpenes include alpha-pinene, myrcene, and beta-caryophyllene, contributing to its pine, citrus, and peppery aromatic and flavor notes. The cannabinoid profile is dominated by THC, with independent lab results reaching up to 25%, placing it among the most potent autoflowering varieties. CBD content is typically less than 1%, allowing the THC to drive the primary effects.

Growing

Cinderella Jack is an autoflowering hybrid that completes its life cycle from seed to harvest in approximately 10–11 weeks under optimal conditions. It is known for its potential to produce XL yields, with some reports indicating substantial harvests from single plants. The strain exhibits a strong resin production and reliable uniformity, making it a grower-friendly option.

The plant morphology is generally compact to medium in stature, with moderate internodal spacing and good lateral branching. It is noted for its vigor and resilience, characteristics inherited from its autoflowering genetics. The buds are typically medium-density with a high calyx-to-leaf ratio, and the flowers frost heavily, indicating high resin output.

Origins & Lineage

Cinderella Jack is a creation of Dutch Passion, a deliberate cross designed to combine the potency and desirable traits of two renowned strains, Cinderella 99 and Jack Herer, with the rapid life cycle of autoflowering genetics. Autoflowering capabilities were integrated using genetics sourced from the Magnum line.

The objective of this cross was to achieve cup-worthy potency within a compact, fast-cycling autoflower format. Cinderella 99 contributes its zesty, tropical, and energetic characteristics, while Jack Herer lends its crisp, cerebral focus. Magnum provided the essential autoflowering trait, vigor, and robust production capabilities. The resulting hybrid has been stabilized to ensure consistent expression of its potent cannabinoid and terpene profiles.
