Fast, Powerful Sativa Leaning Auto with Classic Cinderella Traits

A combination of cannabis legends Jack Herer and Cinderella 99 with Keepers Ruderalis, 1-800-Cinderella-99 Autoflower is a feminized autoflower with pronounced sativa traits and supercharged power, along with a simplified growing schedule that makes it easier than growing a conventional photoperiod plant.

At 24% to 26% THC and around 1% CBD, this strain is not for the faint of heart. Experienced consumers will appreciate the energetic onset and relaxing finish, while those with a lower tolerance should approach this strain with caution.

Since the plant ages and begins to flower regardless of light cycle (as with conventional 12/12 to trigger bloom), these autos offer additional indoor growing flexibility and outdoor harvest planning. Feminized seeds mean even better space utilization as growers can focus on the flower-producing side of the equation.

Autoflower with Recognizable Genetics

The lineage is (Jack Herer x Cinderella 99) x Keepers Ruderalis. Both Jack Herer and Cinderella 99 are renowned for producing bright fruity or citrus aromas and strong resin, and for offering uplifting, clear-headed sativa effects. Ruderalis keeps the cross short and brings the autoflowering trait.

This plant is not a tiny auto. Seedkeepers indicates the indoor and outdoor height is around 59.1 inches. Realistically, growers should expect a five-foot plant if all conditions are right for development. That additional height allows for plenty of flowering sites and is still usable in most home gardens.

The flowers are heavy, dense, and resinous. By the end, growers should see a frosty layer, which is the look they want when growing Cinderella 99. For those who appreciate a lot of trichomes, that cover the finish, and the bags, along with the ease of an autoflower, that is a big part of this cultivar’s attraction.

A Bright, Layered Aroma

From the family tree, we can see that a fresher and sweeter profile is likely rather than one that is more earthy. There are tropical fruits, pineapple, and light flowers in the Cinderella 99 family. The Jack Herer family leans toward more pine, spice, and a clean herbal approach. Each phenotype and growing condition alters the final scent, however, it must lead to a fruit-forward sweetness on top with a sharp finish.

The contrast offered by 1-800-Cinderella-99 Autoflower gives more personality than an auto chosen simply for a high THC content. Bright aromas, sticky flowers, and sativa-leaning effects provide a clear identity.

Uplifting to Relaxing

Seedkeepers reflects the experience as uplifting and relaxing. The energetic aspect of the profile could correspond to conversation, music, creative hobbies, or a chilled afternoon. As the experience progresses the more relaxing side helps to soften the edges without the effect becoming too heavy or one-dimensional.

Potency deserves some respect. THC is listed at 24-26%, so modest amounts may be enough for less experienced consumers. Individual responses vary based on tolerance, setting, harvest timing, and method of consumption, so the effect profile should be seen as a guideline and not a promise.

Growing 1-800-Cinderella-99 Autoflower

It is not the easiest autoflower to take care of, but it is not the hardest either. The difficulty is rated medium, and Seedkeepers suggest it for more experienced growers. Autoflower genetics remove the need to change the lighting schedule, but the plant still requires consistent attention from the beginning.

Mistakes made in the early phase can be troublesome. Plants that are stressed have a limited period to recover before flowering starts. Giving enough water, nutrition, and being gentle, during the early phase, can do more good than being aggressive.

For indoor growing, ensure that the space is at least 5 feet tall from the light to allow for plant growth. Be sure to not overcrowd the top of the plant. When budding, dense flowers will need space and air flow around them to prevent rot. During the vegetative phase of plant growth, use low-stress training to widen the top of the plant and increase light in the lower areas of the plant. Avoid heavy pruning during this phase since recovery will take time and will be limited to the length of the vegetative phase.

When growing, the outdoors should be a bright area with drainage and wind to help dry the plants. The containers should be large enough to allow the root systems to spread. The amount of sunlight, nutrition, climate, and daily health of the plants will determine the yield. Seedkeepers yields for outdoors is 5.3 to 7.1 oz per plant and indoors is 1.6 to 2.0 oz per square foot. When cultivating, consider all aspects of the plants including phenotype, lighting, and climatic conditions, as they will determine the final yield.

1-800-Cinderella-99 Autoflower is ideal for intermediate growers wanting a feminized auto with clear sativa leaning tendencies in the cross. It should also appeal to collectors looking for a Jack Herer/Cinderella 99 cross with more character than a high-THC generic to cross.

With its moderate height, it suits both outdoor and indoor cultivation and its dense, resinous buds with 24% to 26% THC make the finished product very noticeable. If you want an uplifting experience, a fruit-and-citrus family tree, and blooming without having to change the light cycle, this cultivar is a must. Just remember the tradeoff: it prioritizes strength and character over high-end production.
