C99 F4
Also known as: Cinderella 99 F4, KOS C99 F4, KOS Cinderella 99, Cindy 99 F4
Overview
C99 F4 is a fourth-generation inbred line of the legendary Cinderella 99 strain, developed by Kingdom Organic Seeds (KOS) from original Brothers Grimm genetics obtained around 2004. This sativa-dominant hybrid maintains a 75% sativa and 25% indica ratio with a flowering time of 7-8 weeks indoors. The F4 generation has brought out a beautiful purple color that was a hidden trait in the original C99 line, with many plants now showing purple coloration on their leaves and/or calyxes. The strain represents a true-breeding line that has been stabilized through selective breeding, offering more consistency than earlier generations.
This KOS line features two distinct female phenotypes at approximately a 3:1 ratio - a normal phenotype and a citrus phenotype. About one in every 3-4 plants expresses "The Beast" phenotype, which often has a pineapple flavor and smell and yields about 20% more than typical C99 plants. Despite being genetically a smaller yielding plant, this F4 line is known to produce slightly better yields than most C99 variations while maintaining the strain's characteristic fast flowering time and potent effects.

Growing Information
C99 F4 is recommended for True Living Organics (TLO) growing style with a flowering time of 7-8 weeks (50-57 days) indoors. While not genetically a big yielding plant, this line yields better than most C99 varieties but still produces small to medium yields. Plants tend to double in size during flowering and can be grown under MH, HPS, LED, or T5 lights. Not recommended for outdoor growing, especially in humid environments. The strain is known for being easy to grow and highly consistent due to its F4 stabilization. Plants typically reach moderate heights and respond well to various training techniques.
