What is hydroponics?

Hydroponics is defined as a method of growing plants without soil, using nutrient-rich water. This innovative approach involves providing plants with essential nutrients dissolved in water, allowing them to grow in a controlled environment where factors such as pH, nutrients, and light can be carefully monitored and adjusted for optimal growth.

This method is particularly advantageous as it can lead to faster plant growth compared to traditional soil-based agriculture, promotes efficient use of water, and allows for cultivation in areas where soil quality is poor or non-existent. Hydroponics systems often utilize various techniques, such as nutrient film technique, deep water culture, and aeroponics, among others, to foster plant health and productivity while minimizing the space required for cultivation.

The other choices do not capture the essence of hydroponics accurately. Planting in sandy soil, for example, involves traditional soil cultivation methods, while growing plants exclusively in greenhouses is too restricted and does not encompass the versatility of hydroponics, which can also be implemented outdoors or in various controlled environments. Lastly, a technique for drying crops does not relate to the growth of plants at all, but rather to post-harvest processing, further illustrating the distinct nature of hydroponics as a method focused on growth without the
