What term refers to growing plants without soil?

• A. Igneous rock
• B. Hydroponics
• C. Impermeable
• D. Infiltration

Answer: (B)

Growing plants without soil is done by supplying water with dissolved nutrients directly to the roots, often using an inert support medium. This method is called hydroponics. It lets you control exactly which nutrients the plants receive and how much water they use, which can lead to faster growth and the ability to farm in places with poor soil or limited space. Other terms refer to different things: igneous rock is a type of rock formed from cooling magma or lava, impermeable describes a material that water cannot pass through, and infiltration is the process of water soaking into the soil. These do not describe growing plants without soil.
