All you need to grow this legendary strain at home


In this growing guide for Cinderella 99, you will learn several important steps and tips to help you grow this sativa dominant strain. We have created this series to help you grow your favorite strain, and the subject of today’s guide has something of a legend attached.

The strain was allegedly created from seeds found in a 2-gram package of Jack Herer in Amsterdam. Even if this story isn’t true, it is likely that Cinderella is a phenotype of Jack Herer. It was developed by Mr. Soul (Brother Grimm’s) and is the subject of a complicated process.

Apparently, the seeds found in the coffee shop were grown into a strain named Princess. Next, he crossed Princess with Café Girl and Genius to create this marvelous strain. Cinderella 99 is also called C99 or Cindy by its legion of fans and is known for the quality of its cerebral high. Keep reading to learn how to grow C99 but remember, you will probably grow a different Cinderella 99 strain to what you might expect.

Tip #1 – Cinderella 99 Strain Review: What Effects Am I Likely to Feel When Using This Weed?

If you are using Cinderella 99 for the first time, don’t be fooled by the delayed onset of its effects. It will normally take at least 15 minutes and is best described as a ‘creeping’ high. If you make the mistake of taking several more tokes, you will be sorry. The initial head high makes you feel light and euphoric. Its THC content varies significantly; from 13.5% all the way to a powerful 22%.

Soon, you will feel a relaxing body high. It is a popular daytime strain because it provides users with an energy boost. You can safely relax and enjoy a break from your worries, and you can also use it to get through the dreaded afternoon slump; just don’t get caught and fired from your job! The Cinderella 99 high will last around 90 minutes, and you should feel elated and ready to complete whatever tasks stand in your way.

Tip #2 – Difficulty Growing – Is Cinderella 99 For Experts Only?

Cinderella 99’s grow difficulty is classified as easy to moderate. As long as you keep the humidity of your grow room in check, this strain has a high resistance to most diseases and pests. Keep humidity in the 55-65% range during the vegetative stage, and reduce it to 40% by the flowering stage.

Once the relative humidity (RH) of your grow room exceeds 65% for a long period, it increases the risk of mildew, mold and other unwanted biological growth. However, if the RH goes below 30%, it slows growth and hinders photosynthesis. A hygrometer measures humidity and is an essential purchase.

One of the best ways to control humidity is through good ventilation. You can reduce humidity by increasing the amount of air exchanged in the room.

Tip #3 – Cinderella 99 Growing Techniques

The problems caused by excessive humidity levels are exacerbated with thick sativa dominant hybrids such as Cinderella 99. It needs to be topped and trained for an even canopy which allows for good airflow throughout the plant.

For novices, Low-Stress Training (LST) is a good way to train your plant without damaging it. The LST method involves bending the branches of the plant as it grows and tying down extra-long branches. Pulling the top of your Cinderella 99 plants down in an ‘L’ shape will help ensure that the hormone, auxin, will be more equally distributed. The result is a faster-growing plant.

Use special green tape purchased from a garden store to tie down the branches. When you expose several bud sites, the colas of your plants will grow sideways and produce several more colas.

Tip #4 – How Big is the Cinderella 99 Yield?

Cinderella 99 has a very high yield when you use clever growing tactics. While the yield is just 16 ounces per square meter indoors, it can reach a monstrous 35 ounces when grown outdoors. The combination of great taste, high THC, and large yield means that concentrate makers love Cindy.

If you want to make C99 concentrates at home, we urge caution. A lot of people use this strain to create butane hash oil, but it is a dangerous solvent to use. It is easier and safer to make edibles instead of wax, shatter or budder. If you lack the skills to make edibles, find a Cinderella 99 cannabis oil and mix it with a fat or oil for a potent edible mix. If you would prefer to use C99 flower to make edibles, make sure you decarboxylate it in the oven first to unlock its THC.

Tip #5 – Feeding for Cinderella 99

As Cinderella 99 is an easy to maintain plant, there are no special feeding instructions. It grows best when fed organic nutrients. The primary nutrients are Nitrogen, Phosphorus, and Potassium. Provide C99 with lots of Nitrogen in the vegetative stage and cut down as it blooms. A week or two before harvest, consider flushing your plants to remove excess nutrients. Otherwise, you may end up with the unpleasant taste of nitrogen as you toke.

Other crucial nutrients required when feeding Cinderella 99 include Sulfur, Magnesium, and Calcium. Overall, marijuana plants need dozens of nutrients, although micronutrients are only required in relatively small amounts. They include Cobalt, Boron, Copper, Iron, Manganese, Chlorine, and Silicon.

If you grow hydroponically, you have full control over feeding. With great power comes great responsibility, and those who use a hydroponics system are more likely to either overfeed or underfeed their plants. When you use an organic ‘super soil,’ you add things like bone meal and bat guano to boost the soil’s nutrient level. If you do it right, you’ll only need to water the plants and occasionally add carbohydrates.

Tip #6 – Should You Grow This Strain Indoors or Outdoors?

Cinderella 99 can be grown outdoors in the right climate. It offers a higher yield when grown outside and is typically ready for harvest by the end of September. While you get a lower yield indoors, growing this strain in controlled conditions makes life a lot easier. Its size and squat stature make it ideal if you have a tiny grow space. While you can grow it hydroponically, you will enjoy better flavors if you grow Cinderella 99 in soil.

Tip #7 – Cinderella 99’s Flowering Time

Cinderella 99’s flowering time is approximately 8 weeks. When you research any strain, you tend to find generic information. To be fair,most of it will prove somewhat useful, but it is nice to find some tailored information now and then!

With most hybrids, you get good results when you plant between 10 and 16 plants per square meter in 3-4-liter pots, to begin with. After a maximum of three weeks in the vegetative stage, you begin blooming and only need to top once.

Cinderella 99 doesn’t necessarily respond to the above as you might expect. If you have the time, resources and patience, it is worth experimenting with this strain. Perhaps you can use larger but fewer pots, increase the vegetative stage duration, and top several times.

Tip #8 – What is the Ideal Climate for Growing Cinderella 99?

Cinderella 99 is known for its wonderful tropical taste, and if you want it to maintain its flavor, grow it in a consistent climate between 68- and 80-degrees Fahrenheit. It is a high yielding plant that thrives when exposed to a lot of sunshine outdoors, and a lot of light when grown inside.

In the modern era, there are three common types of grow light: High-Intensity Discharge (HID), Compact Fluorescent Lights (CFLs), and Light Emitting Diodes (LEDs). HID lighting has been upgraded, but the core principles remain the same. When growing weed indoors, choose 400W and 600W bulbs and make sure the lights are 12-20 inches above the plant canopy.

CFLs are normally used in small grow rooms but can be very effective as an MH alternative. It works well within the cool white spectrum, and if you place a 250W CFL 4 inches above the canopy, it provides results comparable to a 400W HID bulb that is 12 inches away.

The newest LED systems have caught up to their HID rivals. You can find high-performance kits that draw up to 400W and outperform 600W Metal Halide (MH) and High-Pressure Sodium (HPS) lights.
