Cinderella XX
Also known as: Cinderella 99 XX, C99 XX
Overview
Cinderella XX is an indica-dominant hybrid strain (70% indica/30% sativa) created by Brothers Grimm Seeds as a feminized phenotype of the legendary Cinderella 99 strain. Developed in 2016 by breeder MrSoul (Rick Campanella), this strain represents the culmination of selective breeding techniques to create the ultimate feminized version of Cinderella 99. The strain was created by selecting Brothers Grimm's favorite C99 female, renowned for exceptional resin production, to serve as the pollen donor for their original Princess parent, creating an all-female version that preserves the best qualities of the original Cinderella 99 genetics. Cinderella XX has become known as a 'Grail Strain' among cannabis connoisseurs due to its exceptional quality and uniformity. The strain features striking oversized, club-shaped bright emerald-green buds with deep green undertones, super thick orange hairs, and a frosty coating of vibrantly white crystal trichomes. This strain has gained legendary status over the past two decades as the 'Holy Grail' of indoor marijuana, prized for its consistently excellent phenotype expressions, high THC content, and exceptional bag appeal.

Growing Information
Cinderella XX is considered an excellent strain for both novice and experienced growers. The plant requires a flowering time of 56-65 days (8-9 weeks) and thrives with added silica, calcium, and magnesium supplements. Indoor plants started at 18 inches will finish around 48 inches tall, making them ideal for SOG or SCROG setups with support from tomato cages or stakes. The strain produces vigorous, fast-flowering plants with robust structure and high calyx-to-leaf ratio, resulting in large, tight colas. Outdoor cultivation can produce giant bushes with proper pruning. Average indoor yields range from 4-8 ounces per plant, with outdoor plants commonly producing one-pound yields. The strain is known for its heavy nutrient requirements and may need support due to dense, heavy buds that can cause branch breakage.
