Abstract

Vertical farming using a hydroponics system is a soilless cultivation farming method, in which plants are grown in nutrient-rich water. Industry's most significant problem in recirculating systems is the possibility of the rapid development of microorganisms leading to nutrient-deficient plants. This paper proposes an ultraviolet C (UVC) for water disinfection and yellow sticky traps for this indoor proposed pest control system. The proposed system implements fuzzy logic through an Arduino microcontroller to handle the decision-making and improve monitoring and control of cultivation parameters. The test species used for the experiments is lettuce. Results showed that the proposed system has a higher shoot, root, total biomass, and lower root mass ratio (p<0.05) and had fewer pest infestations than the standard system. This system helps promote chemical-free pathogen and pest control, thereby improving cultivation and plant growth parameters.
