Cinderella 99 is also known as “Holy Grail”. It is a variety of marijuana that enjoyed great popularity in the mid-2000s to the point of being one of the most desired plants.

It is also a very popular variety since then by banks such as Female Seeds or G13 Labs, among many others. On prestigious sites such as Leafly or Seedfinder, it has very favorable opinions. Those who grow it and smoke it once want to smoke it again.

Cinderella 99 is the work of Mr Soul, breeder of the Brothers Grimm Seeds seedbank. His story begins in the Dutch coffee shop Sensi Smile, owned by Sensi Seeds, where Mr Soul acquires a bag of Jack Herer buds.

In one of these buds he finds several seeds that he decides to cultivate, giving rise to three powerful females that were used for some of the best works of this bank. One of them was Princess, which after a long breeding process gave birth to Cinderella 99.

C99 is definitely an Indica-dominant hybrid that comes from a Jack Herer mother and a father of unknown origin. It will never be known from which male the pollen that fertilized that Jack Herer bud came from, although it is known that it came from the Sensi Seeds genetic collection.

How to grow Cinderella 99

It is a plant that we guarantee you will enjoy. It grows fast in any climate and has a very short flowering period despite its Sativa dominance.

If there is an easy to grow and hardy variety, it is our Cindy 99. You will obtain plants of vigorous development that will reach a height of 2.5 meters that will guarantee a great production.

Flowering is very short and it is usual to cut towards the end of September, before the first rains of autumn in some areas can endanger the outdoor harvest.

In indoor it is perfect for SOG cultivation when a mother with contained branching is selected. When small cuttings are grown in pots of maximum 3 liters, thick colas are obtained that will be difficult to maintain vertically.

The speed of flowering also allows the largest number of crops per year, since only about 50 days will be necessary to be able to cut. And despite its Skunk genes, it is not a variety that smells excessively of marijuana, so it is also very discreet.

Features of Cinderella 99

The buds are large, very resinous and heavy. Any extraction lover will enjoy C99 because of its great return.

Cinderella 99 also does not disappoint with its flavor and aromas. It has exotic and sweet hints of fresh exotic fruits such as pineapple and grapefruit that linger in the mouth for a long time, it is really appetizing.

    Had 5 plants outdoor in Bavaria in 2023. Harvest in middle of Oct. Nice plants, not to big (in comparison to others on the same spot, C99 reached 2,4m), buds were dense without mold and with sweet flavour. The smoke is strong and definitely more high than stoned. Got medical weed with 22% and C99 brought similar potency. This is a high recommendable Strain, which I will use furthermore. The only disadvantage is the moderate yield 200g/plant.
