1. History

Cinderella (aka Cinderella 99, Cindy, or just C99) is a Sativa-dominant hybrid dating back to the late 1990s. The most commonly accepted story says that a couple of brothers bought Jack Herer buds in a coffee shop in Amsterdam and found a couple of seeds. The brother then grew the seeds and discovered that the effects were much more potent and psychedelic than any other strain they’ve tried before, naming it Princess due to the beautiful appearance the plant had. Knowing the gem they had in their hands, the brothers then bred their Princess with a male Shiva Skunk, resulting in a Cinderella 88 which was then crossed once more to the original Princess, resulting in the Cinderella 99 we know today.

2. Specifications

The Fast Buds team was able to redesign the genetics and the beautiful old-school strain is now available in auto version. Cinderella Auto offers a terpene mix of sweet tropical fruits that will eave your mouth watering while growing very well in most climates, providing growers of all levels an easy-to-grow plant that delivers top-shelf buds. 

Our auto version of the original Cinderella reaches up to 120 cm and yields up to 550 gr/m2 in as little as 56 - 63 days. Thanks to the insane trichome production, Cinderella Auto produces up to 23% THC and a nice uplifting high that’ll allow you to focus and do the chores before relaxing your whole body and leaving you floating on a cloud. 

3. Week-By-Week Guide

Remember this article serves as a guide and will allow you to know what to expect when growing our Cinderella Auto in similar conditions but keep in mind that plant growth may vary slightly depending on your setup.

This written timeline will help you identify any possible issues and allow you to compare plant growth to know if your plant is growing how it should. So let’s start with our Cinderella Auto week-by-week guide!

Germination - Week 0 

Germination week (aka week 0) is where this weekly guide begins. The grower germinated the seeds directly in the substrate without any issues at all. We usually recommend soaking the seeds in a glass of water for up to 48 hours before transferring the seeds to a paper towel or planting them in the final pot.

Remember that you can germinate cannabis seeds any way you want but cannabis seeds germinate under certain conditions so it doesn’t matter the method, as long as you keep good conditions your seeds will germinate. If it’s your first time germinating cannabis seeds, make sure to leave the glass cup (and eventually the paper towels with the seeds inside) in a dark, cool place. If you’re having problems maintaining high humidity levels,  it’s highly recommended to place a plastic cup over the seedling to maintain high humidity, at least for the first couple of days.

Vegetative Stage - Week 1

If everything is right, your plant should have come out of the soil by week 1. In this case, Cinderella Auto has grown 2 pairs of true leaves so if you’re planning on performing plant training techniques, now would be the right time.

Now, if it’s your first time growing then it’s recommended to go for low-stress training techniques such as tying down the branches instead of high-stress training techniques such as topping. But if you have enough experience you can do whatever you need to, just remember to do it carefully to avoid stunting plant growth.

Vegetative Stage - Week 2

By week 3 from germination the roots will probably have been established and your plants should be growing exponentially. As you can see the Cinderella Auto has grown quite a bit. If you choose to perform plant training techniques, remember to always keep the growing conditions on point. During the vegetative stage you want to have the temperature around 22-28°C and the humidity between 70-75%.

Healthy and happy plants on week 2 of veg.

Always remember that you need to check and adjust the pH depending on the fertilizers you’re using. The nutrient solution’s pH is what allows your plant to absorb the nutrients so if the pH is out of control, your plant won’t be able to eat even if the food is in the soil.

Vegetative Stage - Week 3

This week marks the week before the pre-flowering stage. As your plant gets ready for flowering, you’ll see how the flowering sites start turning light green. This is a sign that your plant will soon transition from the vegetative stage into the flowering stage. Now, keep in mind that if you’re not growing feminized seeds, there’s a high chance that some plants are male so keep an eye out for pollen sacs.

If you’re growing feminized seeds there’s no need to worry about pollen sacs. Just ensure your plants are happy and healthy and in a couple of days, you’ll see the white hairs starting to develop. These white hairs come out of the bracts and are what soon enough will become what every grower aims for: the flowers.

Pre-Flowering Stage - Week 4 

The fifth week from germination marks the pre-flowering stage, aka the transition from the vegetative into the flowering stage. During the pre-flowering stage you’ll see how the white hairs (aka stigmas) start to appear. Plants need more food when they start producing flowers so make sure to feed a Bloom fertilizer that provides more phosphorus and potassium.

With the different nutrient requirements also comes different growing conditions. So during the pre-flowering stage make sure to keep the temperature between 18-25 °C and humidity levels around ranging from 65-60%. Also, if you’re training your plant, now would be the time to stop because plant training can stress cannabis plants during flowering; By now your plant should have the desired structure or size and be ready to start producing beautiful flowers.

Flowering Stage - Week 5 

This week marks the beginning of the first half of the flowering stage. At this stage, trichome production should explode and your plant will probably start reeking of the delicious cannabis smell we all love. If the weed smell is an issue, make sure to install a carbon filter and exhaust fan to eliminate the smell.

If you cannot afford or cannot find the equipment needed, you can always use odor neutralizers which work just fine but actually do not eliminate the smell, just help mask it so if the smell is really an issue and you don’t want to attract unwanted attention, go for carbon filters!

Flowering Stage - Week 6 

During this week you’ll see how the buds are fairly formed but still need to fatten up a bit so make sure to feed Bloom nutrients to provide everything your plants need but make sure you don’t feed in excess because overfeeding can stunt growth and end up affecting plant size and yields.

As the buds continue to fatten up, remember to keep the conditions on point. Keeping the right conditions will prevent bugs and mold from attacking the buds. Mold and bugs can eat the buds from the inside out so always adjust and maintain the humidity around 40-50% and temperatures between 18 - 24 °C.

Flowering Stage - Week 7

This week marks the last week before harvest week. The flowers should be almost ready by now and completely covered in trichomes, giving the flowers that beautiful shiny appearance but don’t get confused, it’s not time to harvest yet!

Even though it seems like your plant is ready and the white hairs are completely orange or brown, the standard harvest practice is to harvest based on the state or color of the trichomes so if possible, grab a magnifier or preferably a jeweler’s loupe and check the trichomes.

Harvesting - Week 8

If you were able to get a magnifier, you’ve probably seen that the trichomes were clear, which is an indication that your plant is not ready for harvest. Now, once the trichomes start changing color then you need to keep an eye out. If you’re looking for a more psychoactive effect then it’s recommended you harvest when the majority of the trichomes are cloudy or milky and if you’re looking for a more relaxing corporal effect, it’s recommended to harvest when the majority of the trichomes have turned amber.

Once the trichomes are good to go, remember to flush thoroughly to enhance the smell and flavor even more. Keep in mind that after harvesting you’ll still have to dry the buds so make sure the drying room is prepared and chop down your plant asap!

4. Terpene Profile

Cinderella Auto offers a deliciously sweet and tropical terpene profile composed of the following main terpenes:

With the secondary terpenes being Linalool, Limonene, and Myrcene.
