The process for growing plants in a water and nutrient solution without soil is called?

• A. Xeriscaping
• B. Hydroponics
• C. Aquaculture
• D. Olericulture

Answer: (B)

Growing plants in a water and nutrient solution without soil is called hydroponics. In hydroponics, the roots receive minerals dissolved in water, often with an inert growing medium to support the plants or the roots may be suspended. This setup lets you control exactly what nutrients the plants get and how much water they use, which can speed up growth and increase yields in controlled environments like greenhouses or indoor systems.

Other terms aren’t describing the same method: xeriscaping involves designing landscapes to minimize irrigation, aquaculture is farming fish and other aquatic animals, and olericulture is the broader study of vegetable cultivation (usually in soil).
