A new modular hydroponic tray system has been developed in Kerala at the Maker Village in Kinfra Hi-Tech Park, Kalamassery, and Cochin University of Science and Technology (Cusat). The system was created by Santosh Kumar M.B., Head of Information Technology at Cusat, and Pradeep Kumar P., CEO of X Boson AI Pvt Ltd. The Government of India granted an official patent to this design, naming it ‘Hydroponic Device for Improving Plant Growth.’ Each tray holds up to nine plants and includes a self-contained nutrient reservoir. This reservoir circulates nutrients continuously without needing external tanks or complex plumbing. This setup uses much less water, making it ideal for homes, urban farms, and small controlled environments. The modular design allows users to start with one tray and expand to multi-unit setups. This makes it useful for micro-farming at home, research projects, and smart city farming. The system solves problems like limited space, water saving, and easy use, providing a smart way to grow plants efficiently in tight urban areas.
