C99 F2
Also known as: Cinderella 99 F2, Cindy 99 F2
Overview
C99 F2 (Cinderella 99 F2) is a sativa-dominant hybrid that represents the second filial generation of the legendary Cinderella 99 strain. Originally developed by Mr. Soul (Rick Campanella) of Brothers Grimm Seeds in the late 1990s, the F2 version maintains the exceptional qualities that made the original famous while offering more genetic stability. The strain emerged from seeds found in a Sensi Seeds Jack Herer package purchased in Amsterdam, which were carefully bred through backcrossing and phenotype selection over multiple generations.
The C99 F2 is particularly notable for combining classic sativa effects with an unusually fast flowering time of 7-8 weeks, making it highly desirable for both commercial and home cultivation. This strain produces dense, resin-coated buds with an exceptional flower-to-leaf ratio, featuring light to medium green coloration with abundant orange pistils and crystalline trichomes. The plants typically remain compact and bushy despite their sativa dominance, rarely exceeding 100cm in height indoors, making them well-suited for indoor cultivation. The F2 designation indicates increased genetic stability compared to the original, with breeders like Cannapot and OriginSeeds working to preserve the authentic pre-2000s genetics from the original Brothers Grimm stock.

Growing Information
C99 F2 is considered moderately easy to grow and is well-suited for both indoor and outdoor cultivation. Indoor flowering time is exceptionally fast for a sativa-dominant strain at 7-8 weeks (49-63 days), with plants staying relatively compact at 80-100cm height. The strain responds well to hydroponics and can yield up to 1.5-2 ounces per square foot indoors, with some growers reporting yields of 0.5-1 ounce per square foot. Outdoor cultivation works best in warm, Mediterranean-like climates where plants can reach 2-3 meters in height. The strain benefits from topping and training techniques, requires good air circulation to prevent mold, and thrives with proper humidity control (40-60% vegetative, 30-40% flowering). Temperature range should be maintained between 68-80°F with at least 600 watts per square meter for indoor growing.
