Lineage: Cinderella 99 × Jack Herer, then crossed with Magnum — Dutch Passion's Auto Cinderella Jack stacks a surprisingly ambitious gene pool into a self-timing autoflower that doesn't ask much from the grower. THC tests typically land between 18–24%, which puts this well above the average auto on the market without requiring a controlled photoperiod schedule.

From seed to harvest runs roughly 10–11 weeks total, and indoor growers regularly pull 400–500 g/m² when given decent light and consistent watering. The aroma leans earthy with a clean sweetness underneath — nothing polarizing, easy to work with in a home grow space. Difficulty is rated easy, and it performs in both indoor and outdoor setups, making it a reasonable choice for Canadian growers who want to squeeze a late patio run before temperatures drop below 15°C.

A solid pick for newer autoflower growers who want above-average THC numbers without the complexity of a photoperiod strain.

Indoor Growing: Expect a flowering time of 10-11 weeks total with yields of 400-500g/m². Plants typically reach 60-120cm indoors.
