Cinderella 99 Auto brings tropical flavor, bright sativa energy, and a fast seed-to-harvest cycle into one standout package. With 24–26% THC and an 80% sativa profile, it delivers a vivid, uplifting experience and resin-rich buds in just 10–12 weeks.

Our breeders crossed (Jack Herer × Cinderella 99) with Magnum Auto to create this mostly sativa autoflower. Ruderalis genetics give it automatic flowering, while the celebrated Cinderella 99 lineage shapes its energetic character and fruity, tropical profile.

Expect a smooth, sweet inhale layered with ripe fruit and tropical notes. A fresh citrus edge brightens the flavor, while dense, crystal-coated flowers release a rich aroma that carries through to the finish.

Cinderella 99 Auto is known for a euphoric, energetic lift that can spark focus and creativity. Mild body relaxation rounds out the experience without taking away its lively edge. It’s a compelling choice for daytime sessions and creative pursuits.

Terpinolene leads with a fresh tropical-fruit and apple aroma, joined by bright, citrus-minty alpha-phellandrene. Nerolidol adds a soft orange-blossom and light-wood note. The terpene blend complements the strain’s upbeat character, while its rich resin makes it appealing for concentrates. Listed use cases include anxiety, migraines, and pain; effects can vary from person to person.

These autoflowering seeds flower automatically, without requiring a change in light schedule. The full cycle takes around 10–12 weeks from germination, and germination is guaranteed. This hardy, moderately easy strain suits newer growers as well as experienced cultivators.

Give seedlings a quality, well-draining medium such as coco, peat, or a blend with perlite, and provide steady light from the start. A consistent 18/6 or 20/4 schedule supports vigorous growth. Keep young plants on a measured feeding routine and check regularly for pests.

Plants can reach about 4.9 feet (1.5 m), with a sativa-leaning structure, sturdy central stem, and productive side branches. Maintain good airflow and comfortable temperatures, and keep humidity in check as flowering progresses. Indoor or outdoor setups can both suit this adaptable variety.

Flowering begins on its own, typically within three to four weeks of germination. As harvest approaches, dense buds swell with resin and develop their sweet, citrus-kissed aroma. Indoor growers can expect around 500–600 g/m²; outdoor yields are listed at 150–200 g per plant under favorable conditions.
