Question

What is it called when you grow plants in water instead of soil?

Answer

This method of growing plants without using soil is known as hydroponics.

Hydroponic systems use nutrient-rich water to provide essential elements needed for plant growth. Instead of relying on soil to supply these components, they rely directly on the water solution itself which contains dissolved minerals that nourish the plant roots. The absence of solid medium like soil allows for more efficient control over environmental factors such as temperature, humidity, light exposure, etc., making it particularly popular among indoor gardeners or those with limited outdoor space.
