Hydroponics is a method of growing plants without soil, using mineral nutrient solutions in a water solvent. Plants are often grown in inert media such as perlite, rockwool, or gravel, which provide support but do not contribute nutrients. The nutrient solution delivers all the necessary elements for plant growth directly to the roots.

There are several types of hydroponic systems, including Deep Water Culture (DWC), Nutrient Film Technique (NFT), Ebb and Flow, Drip Systems, and Aeroponics. Each system circulates the nutrient solution in a different way to provide water, nutrients, and oxygen to the plant roots. For instance, DWC involves suspending plant roots directly in a nutrient-rich water reservoir, while NFT uses a continuous flow of nutrient solution over the roots.

Hydroponic gardening offers several advantages. It can lead to faster plant growth and higher yields compared to traditional soil-based farming because nutrients are readily available to the plants. It also conserves water, as systems can be designed to recirculate water and nutrients, reducing waste. Furthermore, hydroponics can be done in areas with poor soil quality or limited space, such as urban environments or indoors. It also eliminates the need for weeding and can reduce pest and disease problems associated with soil. However, it requires a consistent supply of electricity for pumps and lights, and careful monitoring of nutrient levels and pH is essential for success.
