Question

what is meant by hydroponics ​

Answer 1

Explanation:

Hydroponics is a method of growing plants without using soil (i.e., soil less). This technique instead uses a mineral nutrient solution in a water solvent, allowing the nutrient uptake process to be more efficient than when using soil. There are several types or variations of hydroponics.

Answer 2

Explanation:

The process of growing plants without soil is called hydroponics. Using hydroponics to grow tomatoes means their roots will be suspended in a liquid nutrient solution instead of growing down into dirt. You can see "water" in the word hydroponics if you look closely: hydro means "water" in Greek.
