Cinderalla (99) is a legendary strain from the "Brother Grimm"
The Brother grimm stopped trading in 2004 and after 11 years they are back as of Aprill 20th 2016.
Here is an explanation of their cubing process. The Brother Grimm have been famed for their highly stable crosses and you too can now use their technique.

Can you explain the ‘cubing’ process used to make the Cinderella?
The breeding technique called “cubing” (because there are 3 backcrosses involved) works as follows:

1. Pollinate a flowering clone of the chosen female with the pollen of a related male, preferably her father or a brother – to preserve any female traits that are linked to the male side of the family. An unrelated male won’t have the Y-chromosome of the chosen female’s family & therefore any Y-linked traits of the family will always be missing in the seed line. The resulting seeds contain 1/2 the original female’s genes and 1/2 those of the male.

2. Grow the above seeds & flower them.

3. Pollinate a flowering clone of the chosen female with pollen from a male selected from the above group. These seeds contain 1/2 the chosen female’s genes plus 1/4 more from the male being 1/2 her genetics too. I call this first back-cross generation .75 to capture the idea that it’s 3/4 of the original female’s genetics.

4. Grow the above seeds & flower them.

5. Pollinate a flowering clone of the chosen female, using a selected male from the above generation. These seeds contain 7/8 the original genes (1/2+3/8), so this second back-cross is the .88 generation.

6. Grow the above seeds & flower them.

7. Pollinate a flowering clone of the original female with pollen from a selected male off the above generation. These seeds contain 15/16 the original genes (1/2+7/16), in other words, so we’ll call this third back-cross the “.94” generation.

Theoretically, this will be a stable, true-breeding seed line from which all females are replicas of the original.
