Hydroponics: Growing Plants Without Soil Through Innovative Techniques

Hydroponics is a method of growing plants without soil, using nutrient-rich water. This technique allows plants to grow faster and healthier by providing direct access to nutrients. Historically, civilizations like the Babylonians and Aztecs used hydroponic methods. Modern applications include NASA's space missions. Hydroponics offers advantages such as faster growth, higher yields, and reduced pesticide use. It requires less water and can be practiced in limited spaces, making it environmentally friendly and efficient.
