The Cinderella 99 Auto seeds are an autoflowering, sativa-dominant variety with a high THC content (24-26%). They stand out for their fruity, sweet and tropical flavour and a euphoric, powerful and relaxed effect, making them a great daytime choice for growers who want an uplifting, quick-finishing harvest.
The Cinderella 99 Auto seeds deliver a modern, autoflowering take on a legendary sativa. Built for speed and clarity, this variety pairs a strongly sativa-leaning structure with generous resin production and a bright, tropical aroma. It has earned a reputation among growers who want a cerebral, energising smoke without a long wait from seed to jar.
This cultivar comes from crossing (Jack Herer x Cinderella 99) with Magnum Auto, adding ruderalis genetics so the plant flowers automatically. The result is a mostly sativa profile of 20% Indica and 80% Sativa in an autoflowering seed format. The original Cinderella 99 is celebrated for its clear, uplifting character, and the Cinderella 99 Auto seeds keep that heritage alive while making it far easier to run in short seasons or compact spaces.
Expect a fruity, sweet and tropical flavour carried by terpenes such as Alpha-Phellandrene, Alpha-Pinene, Terpineol, Delta-3-Carene, Nerolidol and Terpinolene. The nose is citrusy and fresh, with a candied sweetness on the exhale. Effects lean euphoric, powerful and relaxed, offering a lucid, motivating head lift with a gentle body ease. This makes the variety a natural fit for daytime use, creative work or social sessions where mental clarity matters.
As an autoflower, the total life cycle from seed runs about 10 to 12 weeks. Plants reach around 150 cm and prefer a dry climate, with an all-season harvest window thanks to the automatic flowering. Indoor yields land between 500 and 600 g/m2, while outdoor plants can return 150 to 200 g/plant. Growth is compact and resilient; a light, airy substrate such as coco coir or peat with perlite helps protect the roots and keeps the terpene profile crisp. Because the plant does not rely on a light-schedule change to flower, the Cinderella 99 Auto seeds are well suited to balcony grows, stealth setups and regions with shorter summers. Keep feeding light in the early weeks, increase gradually through the stretch, and finish with a proper flush so the smoke stays smooth and the sweet, tropical notes come through clean.
These Cinderella 99 Auto seeds suit growers who value speed, simplicity and a sativa high. Beginner-friendly and forgiving, they reward first-time cultivators while still satisfying experienced hands looking for a quick, high-THC autoflower. Their compact structure fits tight spaces, and the fast turnaround allows several runs across a single season. If you want an uplifting, tropical-tasting harvest with minimal fuss, this variety is a dependable and consistently rewarding choice.
