Some of the most common plants grown hydroponically include tomatoes, lettuce, strawberries, and basil.There are a number of different hydroponic techniques that can be used to grow food on water. The most common methods include:*
-*Deep water culture (DWC)
In DWC systems, plants are suspended in a nutrient-rich water solution. The roots of the plants are constantly submerged in the water, which provides them with all of the nutrients they need to grow.
-
-*Nutrient film technique (NFT)
In NFT systems, a thin film of nutrient-rich water is continuously circulated over the roots of the plants. This method provides the roots with a constant supply of nutrients and oxygen.
-*Aeroponics
In aeroponic systems, the roots of the plants are suspended in the air and are misted with a nutrient-rich solution. This method provides the roots with a high level of oxygen, which can promote rapid growth.
Hydroponics has a number of advantages over traditional soil-based gardening. These advantages include:*
-*Increased yields
Hydroponic systems can produce higher yields than soil-based gardens, as they provide plants with a more controlled environment and a constant supply of nutrients.
