A-13 x C99

Cannabis Strain by Dutch Flowers

Introduction
A-13 x C99 from Dutch Flowers combines two legendary Brothers Grimm genetics: Apollo 13 and Cinderella 99. This mostly sativa cross represents a piece of cannabis breeding history, though Dutch Flowers no longer operates as a seed company—making this cultivar a relic of an earlier era in commercial cannabis genetics.

Lineage
Apollo 13 (A-13) emerged from Brothers Grimm's work with P75—a mysterious female of unknown origin that produced exceptional offspring. Crossed with Genius (a Cinderella 99/Apollo 11 hybrid), A-13 became known for potent, trippy effects and complex aromatics. Cinderella 99 (C99), perhaps the most famous Brothers Grimm creation, descended from a single seed found in Jack Herer flower, developed through extensive cubing to stabilize desirable traits. Combining these two genetics creates a mostly sativa expression carrying the best of Brothers Grimm's late-1990s breeding achievements.

Terpenes
Both parent strains express terpinolene-dominant profiles with tropical, citrus, and floral characteristics. A-13 contributes spicy, almost hallucinogenic aromatic notes, while C99 adds sweet pineapple and grapefruit characteristics. The combination should produce complex, fruit-forward aromatics with underlying spice—neither parent was known for subtlety.

Growth
Without documented flowering time for this specific cross, growers should expect mostly sativa timelines: likely 8-10 weeks minimum. Both parents produce medium-height plants with moderate stretch, meaning the cross should remain manageable for indoor cultivation. Regular seeds require sex identification. The "does not exist any more" status indicates finding authentic genetics requires hunting through preservation-focused seed collectors.

Effects
Effects from this sativa-dominant combination likely emphasize cerebral stimulation and potential psychedelic character—both parents were renowned for intense, mentally active experiences rather than physical sedation.

Documentation
Dutch Flowers' closure means no official source exists. Genetic preservation communities may maintain authentic lines, though verification proves challenging for discontinued strains.
