Need for Controlled Environment Agriculture (CEA) also known as weather and climate proof farming was never so great, as now in the times of climate change for meeting millennium development goals of global nutritional security. This has brought hydroponic farming at the core of secure food production systems. hydroponic systems focus on the core elements of plant growth i.e. light, water, nutrients and CO2 while eliminating all other collateral elements. It can be further summed up that soul of hydroponics lies in eliminating soil as growing media and meeting the plant nutrient and water requirements through nutrient solution alone. Innovations in nutrient solution recipes, delivery systems and management has transformed vertical farming in the recent times.
