Description

Cinderella 99 Auto Strain Info

Cinderella 99 Auto is an 80% Sativa/20% Indica autoflowering strain created from Jack Herer, Cinderella 99, and Magnum Auto genetics. Its THC range of 24-26% gives the smoke a strong yet active personality, especially for users who enjoy a clear mental rise with a relaxed finish. Plants reach around 4.9ft (150cm), showing a taller Sativa-style structure while keeping the convenience of automatic flowering. The flavor leans fruity and tropical, with sweetness shaping the finish. Effects begin uplifting, then settle into a smoother hybrid rhythm.

Genetics

Cinderella 99 Auto was bred from Jack Herer, Cinderella 99, and Magnum Auto, combining classic Sativa energy with autoflower practicality. Jack Herer contributes a clear cerebral push and old-school daytime character. Cinderella 99 adds tropical sweetness and a creative, upbeat profile, while Magnum Auto brings automatic flowering behavior and a faster route to harvest. The result is a mostly Sativa auto that keeps the spirit lively while making the grow easier to schedule.

Flowering Time

Cinderella 99 Auto goes from seed to harvest in 70-84 days, or around 10-12 weeks. It begins flowering automatically after early vegetative growth, so growers do not need to change the light cycle to trigger bloom. Strong lighting and steady feeding help it use the full window well. The grow takes longer than many autos, but the extra time supports stronger yield and fuller resin development.

Yields

Indoors, Cinderella 99 Auto can produce around 1.6-2oz/ft² (500-600g/m²) under quality LEDs and controlled humidity. Outdoors, healthy plants return about 5.3-7.1oz (150-200g) per plant in favorable conditions. Indoor production is clearly the stronger side here, especially when the plant receives enough light and root space.

Effects

The high starts with a clean euphoric lift that can make the mind feel sharper and more willing to play. Energy comes through in a friendly way, giving creative tasks a brighter pulse. As the session continues, a mild body relaxation arrives without dragging the whole mood downward. Cinderella 99 Auto suits daytime use, social plans, or low-pressure creative work that needs a little tropical spark.

THC and CBD Levels

With 24-26% THC, Cinderella 99 Auto sits in a strong potency range for an autoflower. CBD is not officially specified, so the experience is shaped mainly by THC and terpene expression. The Sativa dominance gives the effect its uplifting character, while the small Indica share helps smooth the landing. Newer users should keep the first dose modest.

Smell and Taste

The aroma opens with tropical fruit and a sweet candy-like softness. On the inhale, the fruity side feels bright and juicy, giving the smoke an easy daytime feel. The exhale leaves a warmer sweetness that lingers without becoming heavy. It is simple in the best way: sunny, smooth, and built around pleasure rather than mystery.

Grow Tips

Cinderella 99 Auto can reach 4.9ft (150cm), so it needs more vertical room than a tiny auto. It prefers Mediterranean-style conditions around 70-85°F (21-29°C), with strong light and well-draining soil. Since autoflowers recover best from gentle handling, early planning matters.

  • Use an 18/6 or 20/4 light schedule indoors for stronger yields.
  • Keep RH around 55-60% early, then lower it to about 40% in flower.
  • Choose coco coir or a perlite-rich substrate for balanced moisture.
  • Use gentle LST if height control becomes necessary.
  • Reduce humidity near harvest to protect resinous buds.
