Cinderella 99 is a sativa leaning reference line created by MrSoul and Brothers Grimm Seeds. Its development began in 1996 with Princess, a selected female grown from a seed found in a Jack Herer flower. Repeated backcrosses to Princess produced P.50, P.75, P.88 and P.94. Princess and P.94 finally produced the original Cinderella 99.
Cinderella 99, often called C99 or Cindy, combines a relatively short flowering period with a slender, well branched plant structure and an unusually well documented breeding history. The strain is not simply Jack Herer × Shiva Skunk. That shortened formula removes Princess and the repeated backcrossing process from the actual story.
The distinction matters. Jack Herer was the maternal plant of the flower in which the original seed was found. The pollen donor responsible for that seed remained unknown. Shiva Skunk was introduced later as the selected male used for the first controlled cross with Princess. Every later generation was crossed back to Princess.
Cinderella 99 in one sentence
Cinderella 99 is a Brothers Grimm seed line released in 1999 that used repeated backcrossing through P.50, P.75, P.88 and P.94 to transfer the Princess selection into seed form.

Cinderella 99 explained: What is C99 really?
Cinderella 99 is a reference line developed by MrSoul at Brothers Grimm Seeds. The starting point was Princess, a distinctive female selected in 1996 from a seed found in a Jack Herer flower.
Princess was first crossed with a male Shiva Skunk plant. This produced P.50. Selected males from that generation were then crossed back to Princess. The process continued through P.75, P.88 and P.94.
The final combination of Princess and a selected P.94 male produced Cinderella 99. The regular seed line was released in 1999.
Princess
The female starting plant with Jack Herer as the known maternal side and an unknown pollen donor.
Shiva Skunk
The male plant used to create the first P.50 generation.
Cinderella 99
The final seed line from Princess and P.94 with a theoretically very high proportion of the Princess genetic background.
C99 is therefore not a conventional two parent cross. It is the result of a breeding programme using repeated backcrossing across several generations.
The origin of Princess in 1996
The story began in 1996 during a trip to Amsterdam. MrSoul found several seeds in a Jack Herer flower purchased at the Sensi Smile coffeeshop.
One of these seeds produced a female plant named Princess. She showed an unusual combination for a sativa leaning line: relatively compact structure, short maturation, substantial resin formation and a fruit driven profile with a pronounced pineapple direction.
Princess was preserved as a clone for many years. This allowed the same female starting plant to remain available throughout the later cubing process.
Important: Princess was not an officially released Jack Herer selection from a standard seed pack. She came from a chance seed found in a Jack Herer flower.
Why the pollen donor behind Princess remains unknown
The maternal side of Princess can be connected to the Jack Herer flower. The male plant responsible for the original seed was never documented.
This means:
- Jack Herer is a confirmed part of the Princess background.
- The second genetic contribution to the original seed is unknown.
- Princess should not be treated as genetically identical to Jack Herer.
- Jack Herer × Shiva Skunk is not a complete formula for Cinderella 99.
Shiva Skunk was introduced later by MrSoul for the first controlled cross with Princess. The unknown father of Princess and the later Shiva Skunk male are therefore separate genetic roles.
The correct short formula
Princess × P.94 is the direct formula for the original Cinderella 99. Jack Herer and Shiva Skunk explain important parts of its development but not the complete final cross.
The role of Shiva Skunk in C99 genetics
MrSoul used pollen from a resinous Shiva Skunk male to pollinate Princess for the first controlled generation. The resulting seeds were called P.50.
Shiva Skunk was not introduced again in every following generation. Its direct role was the production of P.50. Selected males from each later generation were then crossed back to Princess.
The Skunk side was intended to contribute stronger branches and a more supportive plant framework. Princess herself could produce heavy flower clusters that placed substantial pressure on her branches.
Skunk #1 Origin and Genetics provides the wider historical context for the Skunk family.
What does cubing mean in Cinderella 99?
Cubing in this context describes repeated backcrossing of selected male offspring to the same female starting plant. The aim was to reproduce the important characteristics of Princess in a seed line.
The simplified process was:
- Princess was crossed with a Shiva Skunk male.
- Suitable males were selected from P.50.
- These P.50 males were crossed back to Princess.
- New males were selected from P.75.
- The process continued through P.88 and P.94.
- Princess × P.94 produced Cinderella 99.
Each backcross increased the theoretical proportion of Princess genetics. The male plants were also selected according to the breeding goals rather than chosen at random.
Cubing is therefore more than a mathematical calculation. The result depends on selection, population size, testing and the actual inheritance of individual traits.
Backcross vs Linebreeding explains the broader breeding distinction.
P.50, P.75, P.88 and P.94 explained
| Generation | Cross | Theoretical Princess proportion | Role in the programme |
|---|---|---|---|
| P.50 | Princess × Shiva Skunk | 50% | First controlled generation using Shiva Skunk as the male side |
| P.75 | Princess × selected P.50 male | 75% | First backcross to Princess |
| P.88 | Princess × selected P.75 male | 87.5% | Further movement towards Princess |
| P.94 | Princess × selected P.88 male | 93.75% | Male parent generation of the final C99 |
| Cinderella 99 | Princess × selected P.94 male | 96.875% | Final regular seed line |
The percentages describe the theoretical expected contribution of the repeatedly used female. They do not mean that every visible characteristic appears in exactly the same proportion.
Genetic recombination and phenotype remain relevant. Genotype vs Phenotype in Cannabis provides the necessary foundation.
Why is the strain called Cinderella 99?
The name connects the breeding story with the familiar fairy tale. A chance seed led to Princess and later to one of the most recognised lines from Brothers Grimm Seeds.
The number 99 refers to the year in which the original regular seed line was completed and released.
Cinderella therefore describes the path from an unplanned seed discovery to a breeding reference. C99, Cindy 99 and Cindy are common shortened names for the same historical line.
The original regular Cinderella 99 from 1999
The seeds created through the original cubing process were regular. They could produce male and female offspring and formed the basis of the Cinderella 99 release in 1999.
Brothers Grimm Seeds lists the direct cross as Princess × P.94. The regular version is particularly relevant when considering the original selection logic and the use of C99 as breeding material.
At Cannoptikum, the regular version carries product ID 94328. Flowering takes approximately 56 to 65 days. The profile is fruit driven, often compared with Hawaiian Punch and accompanied by a stronger, slightly funky undertone.
Classification: Regular means the seeds may produce male and female plants. It does not mean that every individual plant is a complete copy of Princess.
The feminized Cinderella 99 from 2016
The original C99 released in 1999 was not a feminized line. According to Brothers Grimm Seeds, MrSoul began producing feminized Cinderella 99 seeds in 2016.
The current feminized version available at Cannoptikum is also listed as Princess × P.94. It continues the historical genetic space in a seed format directed towards female flowering offspring.
The feminized version has approximately 56 to 63 days of flowering, a sativa leaning structure and a tropical, sweet and lightly earthy profile direction.
Regular and feminized should not be read as completely separate strains. They are two seed formats within the Cinderella 99 line maintained by Brothers Grimm.
Is Cinderella 99 Sativa or Indica?
Cinderella 99 is classified by Brothers Grimm Seeds and Cannoptikum as a sativa leaning hybrid. The strain nevertheless combines traits that differ from the common image of a tall, late flowering Sativa.
Recurring C99 traits include:
- slender and responsive plant structure
- well developed side branches
- moderate stretch
- relatively short flowering time
- more compact height than many classic Sativa lines
- dense and resinous flower sites
This combination made Princess and later Cinderella 99 useful breeding material. A sativa leaning architecture could be combined with a substantially shorter maturation window.
Direct answer
The original Cinderella 99 by Brothers Grimm Seeds is sativa leaning but remains more compact and faster than many traditional Sativa lines.
Plant structure and recurring C99 traits
Cinderella 99 usually grows with a slender to medium width and develops a useful side branch framework. Height remains manageable when flowering begins early. Outdoors, the line can become substantially wider and taller.
Recurring structural traits include:
- strong central stem
- well developed side branches
- moderate internodal spacing
- useful flower to leaf ratio
- visible stretch without extreme Sativa height
- need for support when branches carry substantial weight
Brothers Grimm Seeds describes C99 as suitable for multi branch plants, even canopies, SOG and ScrOG. The chosen method does not change the genetics but can direct the existing branching and available area differently.
Mark, Cannoptikum Crew: The balance matters with C99. The line is lighter and more responsive than a compact Indica but remains considerably easier to control than many long Sativa genetics. Side branches should be organised evenly from an early stage.Profile direction and terpenes of Cinderella 99
The original C99 direction is commonly described through tropical fruit, pineapple, citrus, sweet notes and a stronger background. The regular Brothers Grimm version is also associated with a fruit profile similar to Hawaiian Punch.
The feminized version at Cannoptikum is described as tropical, sweet, fruity and lightly earthy. Cinderella Pineapple shifts the selection further towards pineapple and citrus.
A single universal terpene profile cannot be established from these descriptions. Actual expression depends on the seed population, selection, phenotype and conditions.
A factual classification should therefore combine:
- original version or descendant
- regular or feminized seed format
- specific seed bank
- documented cross
- described profile direction
Cannabis Terpene Profiles provides the wider foundation.
Why Cinderella 99 and C99 versions differ
The C99 name has been used by different seed banks for many years. Not every version descends from the same Princess × P.94 line.
Original continuation
Brothers Grimm Seeds works directly with the Cinderella 99 line created by MrSoul.
Reproduction or selection
Other seed banks may use older C99 seeds, F2 generations or their own selections.
Similar name only
A product may use the C99 name even when a different cross is documented.
The Cannoptikum range demonstrates this distinction. Cinderella 99 by Brothers Grimm Seeds is listed as Princess × P.94. C99 by G13 Labs is listed as Jack Herer × Haze.
Both products may show short flowering, fruit driven profiles and sativa leaning structure. Their documented genetics are still not identical.
Cinderella 99 comparison at Cannoptikum
The following products show the original feminized release, the regular original version, a separate C99 interpretation and two important descendants.
Cinderella 99 Feminized by Brothers Grimm Seeds
Cinderella 99 by Brothers Grimm Seeds is the main feminized reference in the Cannoptikum range. The documented cross is Princess × P.94.
Flowering takes approximately 56 to 63 days. The plant is classified as sativa leaning, remains manageable indoors and develops a well branched framework.
Product role: feminized original continuation by MrSoul and Brothers Grimm Seeds.
Cinderella 99 Regular by Brothers Grimm Seeds
Cinderella 99 Regular by Brothers Grimm Seeds is the version most closely connected to the original 1999 release. The cross is also Princess × P.94.
Flowering takes approximately 56 to 65 days. The regular seed format may produce male and female offspring and is relevant for selection, preservation and further breeding work.
Product role: regular original format connected directly to the cubing programme.
C99 by G13 Labs
C99 by G13 Labs is listed at Cannoptikum as Jack Herer × Haze. This differs from Princess × P.94 and should not be presented as genetically identical to the original C99.
The feminized line has approximately 55 to 60 days of flowering and a tropical profile with grapefruit, pineapple and citrus.
Product role: independent C99 interpretation with a different documented cross.
Cinderella Pineapple by Brothers Grimm Seeds
Cinderella Pineapple by Brothers Grimm Seeds builds on the original Cinderella 99 line and shifts the selection further towards a pineapple profile.
Flowering takes approximately 60 days. Plant structure and development remain closely connected to the C99 genetic space.
Product role: fruit directed selection within the Cinderella family.
Rosetta Stone by Brothers Grimm Seeds
Rosetta Stone by Brothers Grimm Seeds combines a Jack Herer female with Cinderella 99 as the pollen donor.
Flowering takes approximately 56 to 70 days depending on expression. Rosetta Stone shows how C99 was used to make a more strongly Jack Herer influenced framework faster and more compact.
Product role: classic C99 cross with Jack Herer.
| Product | Seed type | Documented cross | Classification | Time reference |
|---|---|---|---|---|
| Cinderella 99 Brothers Grimm | Feminized photoperiod | Princess × P.94 | Sativa leaning original genetic space | 56 to 63 days flowering |
| Cinderella 99 Regular | Regular photoperiod | Princess × P.94 | Regular original format | 56 to 65 days flowering |
| C99 G13 Labs | Feminized photoperiod | Jack Herer × Haze | Separate C99 interpretation | 55 to 60 days flowering |
| Cinderella Pineapple | Feminized photoperiod | Original Cinderella 99 selected towards pineapple | C99 family selection | About 60 days flowering |
| Rosetta Stone | Feminized photoperiod | Jack Herer × Cinderella 99 | C99 descendant | 56 to 70 days flowering |
Why C99 by G13 Labs must be considered separately
C99 by G13 Labs uses the recognised shortened name but has a different cross in the Cannoptikum data sheet. The line is listed as Jack Herer × Haze.
It shares several visible characteristics with the wider C99 profile:
- sativa leaning structure
- short flowering period
- tropical and citrus profile direction
- moderate height
The documented ancestry is still not Princess × P.94. The version should therefore be treated as an independent interpretation.
The name is a search signal. The documented cross is the more important genetic signal.
Cinderella 99 family and important descendants
C99 became an important parent because it could contribute sativa leaning structure, short flowering and useful branching to later crosses.
Cinderella Pineapple
A C99 direction selected further towards pineapple and tropical fruit within the Brothers Grimm programme.
Rosetta Stone
Jack Herer × Cinderella 99 connects a classic Jack Herer framework with the faster C99 side.
Space Queen
Romulan × Cinderella 99 combines a more compact Romulan structure with the more responsive and faster C99 development.
Further Brothers Grimm lines use Cinderella 99 directly or indirectly as a genetic component. These include Durban Thai × Cinderella 99 and several Apollo related lines.

Cinderella 99 strain or C99 strains?
The singular Cinderella 99 strain describes the historical reference line created by MrSoul and Brothers Grimm Seeds. This is why the main title uses the singular form.
The plural C99 strains is useful when comparing several versions and descendants:
- regular and feminized Brothers Grimm versions
- separate C99 interpretations from other seed banks
- C99 F2 generations
- selections such as Cinderella Pineapple
- crosses such as Rosetta Stone and Space Queen
The singular asks about origin and identity. The plural asks about the wider genetic family.
Context: Cinderella 99 strain, C99 or genetics?
The main questions around Cinderella 99 concern Princess, the cubing process used by Brothers Grimm Seeds, the generations from P.50 to P.94 and modern C99 versions.
This guide therefore focuses on:
- the seed discovery in 1996
- Princess as the female starting plant
- the unknown original pollen donor
- Shiva Skunk as the male side of P.50
- the cubing process through P.50, P.75, P.88 and P.94
- Princess × P.94 as the direct C99 formula
- the regular release in 1999
- the feminized version from 2016
- original releases and different C99 lines
- C99 as a parent in later crosses

Cinderella 99 strain FAQ
Cinderella 99 is a sativa leaning reference line from MrSoul and Brothers Grimm Seeds. It was created through repeated backcrossing of P.50, P.75, P.88 and P.94 to the female starting plant Princess.
The direct original formula is Princess × P.94. Princess came from a seed found in a Jack Herer flower. The original pollen donor remained unknown. Shiva Skunk was later used to create P.50.
No. This formula is too simplified. Shiva Skunk was used to create the first P.50 generation. The final Cinderella 99 was produced from Princess × P.94 after several backcrosses to Princess.
P.94 is the generation produced after repeated backcrossing to Princess. It theoretically contains 93.75 percent Princess genetics. A selected P.94 male was crossed to Princess to create Cinderella 99.
Cubing here means repeatedly crossing selected male offspring back to the same female starting plant, Princess. The goal was a seed line that carried important Princess traits as consistently as possible.
The original Cinderella 99 is classified as a sativa leaning hybrid. It remains more compact and matures faster than many traditional Sativa lines.
The feminized Brothers Grimm version takes approximately 56 to 63 days. The regular version is listed at approximately 56 to 65 days. Other C99 versions may differ.
Princess was selected in 1996. The regular Cinderella 99 was completed and released in 1999. MrSoul began producing feminized Cinderella 99 seeds in 2016.
No. Brothers Grimm Seeds lists Princess × P.94. Other seed banks may work with reproductions, F2 generations, independent selections or entirely different crosses.
The regular or feminized Cinderella 99 from Brothers Grimm Seeds provides the clearest connection to the original line. Other versions should be assessed through their documented cross.
Conclusion
Cinderella 99 is not a generic name for every short flowering and fruit driven Sativa line. The historical reference begins with Princess, introduces Shiva Skunk in P.50 and then returns repeatedly to Princess through P.75, P.88 and P.94.
The direct formula Princess × P.94 explains the original C99 more accurately than the common simplification Jack Herer × Shiva Skunk. Jack Herer belongs to the confirmed maternal side of the original seed. The first pollen donor remained unknown. Shiva Skunk was introduced later for the cubing programme.
The regular version from 1999 and the feminized Brothers Grimm format from 2016 form the clearest original genetic space. C99 releases from other seed banks and crosses such as Rosetta Stone, Cinderella Pineapple or Space Queen must be classified through their own ancestry.
