Hydroponic farming is a method of growing plants without soil, where plant roots are directly exposed to a nutrient-rich water solution. Unlike traditional farming methods which rely on soil as a medium for plant growth, hydroponic farming utilizes various systems such as nutrient film technique (NFT), deep water culture (DWC), or aeroponics to deliver nutrients directly to the roots. This precise control over nutrient delivery, along with the absence of soil-borne pests and diseases, sets hydroponic farming apart from conventional methods.
