What is one advantage of hydroponics?

The advantage of reduced water usage in hydroponics is significant because this method of growing plants uses a system that recirculates water and nutrients, allowing for far less water to be consumed compared to traditional soil-based agriculture. In hydroponic systems, plants receive all needed nutrients and moisture directly, resulting in a much lower evaporation and runoff, which can lead to up to 90% less water usage overall.

In contrast to the other options, hydroponics does not improve soil fertility, as it does not rely on soil at all. It also does not facilitate faster pest propagation; in fact, it can often reduce pest issues because the controlled environment minimizes exposure to pests found in soil. Lastly, hydroponic systems can be designed to function independently of weather conditions, as they are often utilized in indoor settings or greenhouses, providing a consistent growing environment regardless of outside climate factors.
