Science Notes - Hydroponics

- 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.
