- Hydroponics is the method of growing plants without soil, using mineral nutrient solutions in a water solvent.
How It Works
- Terrestrial plants can be grown with their roots directly exposed to the nutrient solution.
- Alternatively, roots may be supported by an inert medium such as gravel.
- Nutrients can come from various sources, including fish waste or duck manure.
Examples of Hydroponic Crops
- Tomato
- Cucumber
- Red chili
- Lettuce
- Spring onions
- Peppers
- Spinach
- Strawberries
- Blueberries
Historical Note
- Dr William Gericke perfected hydroponic techniques in the 1940s and is credited with inventing the concept of hydroponics.
