The objectives of this research were to study the growth rate of microbial sludge in the fermented juice and to study the efficiencies of fermented juice and melodies on Fairy Rose growth. In the experiments the growth rate of microbial sludge was analyzed with 10 parameters for 4 weeks. Moreover the Fairy Rose was divided into 2 groups used and non-used the fermented juice. Each experimental group was tested with 3 types of melodies including jazz classical and Mozart. All experiments were set 3 replications by the total number of 24 Fairy Roses. The growth of the Fairy rose was analyzed by considering the number of leaf Height length of root and mass. The experimental results showed that the growth of microbial sludge in fermented juice was good and produced microbial sludge in fermented juice approximately 1063 ±158 mg/L on average. The Fairy Rose more growing with water and fermented juice. The number of leaves was 144±11 leaves in average Height was 30±1 cm in average Length of root was 38±8 cm in average and weight of Fairy Rose at the end of experimentation was found 400 g in average. In the case of melody affected Fairy Roses growth was classical. The growth of fairy roses found that the number of leaves was 143±6 leaves in average height was 29±1 cm in average Length of root was 34±1 cm in average and weight of Fairy Roses at the end of experimentation was 93 g in average
