What is the practice of raising plants in a nutrient liquid solution called?

The practice of raising plants in a nutrient liquid solution is known as hydroponics. This method involves growing plants without soil, utilizing a nutrient-rich water solution instead. Hydroponics allows for the efficient delivery of nutrients directly to the plant roots, promoting faster growth and higher yields compared to traditional soil-based methods.

In hydroponic systems, various techniques may be employed, such as deep water culture or nutrient film techniques, to ensure that plants receive the necessary water and nutrients. This method is particularly useful in areas with poor soil quality or limited arable land.

Other options do not accurately describe this practice. Aeroponics involves growing plants in an air or mist environment, where roots are suspended in the air and receive nutrients through a mist. Soil culture, on the other hand, refers to traditional methods of growing plants in soil. Germination is the process by which seeds sprout and begin to grow but does not pertain specifically to how plants are grown after sprouting.
