The Basics of Hydroponics

Hydroponics is a fascinating form of agriculture that allows plants to grow in a water-based, nutrient-rich solution, eliminating the need for soil. There are many different hydroponic methods you could use based on space constraints and plant needs, making it highly adaptable for educational settings. The most common types of hydroponic systems include:

• Wick Systems: The simplest type of hydroponic system, where a wick passively transports nutrients to the plants.

• Deep Water Culture (DWC): Plants are supported on a floating material while the roots hang below in a nutrient solution.

• Nutrient Film Technique (NFT): An active hydroponic system that uses pumps to circulate the nutrient solution through shallow channels where the plant roots lie. 

• Aeroponics: Plant roots hang in the air and are periodically misted with nutrients.

The benefits of hydroponics extend beyond environmental factors; they include logistical advantages such as requiring less space and alleviating soil quality concerns, making it ideal for urban schools that might lack large outdoor areas. These systems can be set up indoors, such as in a classroom or on a rooftop, providing a year-round gardening opportunity that is particularly beneficial in colder climates.
