Syvävesiviljely

Syvävesiviljely, also known as deep water culture (DWC), is a hydroponic growing method where plants are suspended in a nutrient-rich water solution. In this system, the plant roots are submerged in the water, and an air pump with an air stone is used to oxygenate the solution. This constant supply of oxygen is crucial for root health and prevents root rot.

The plants are typically held in net pots filled with an inert growing medium, such as clay pebbles or rockwool, which supports the stem and allows roots to grow down into the reservoir. The nutrient solution is a carefully balanced mixture of water and essential minerals that the plants need for growth. The reservoir can be made of various materials, like plastic tubs or tanks, and needs to be opaque to prevent light from reaching the nutrient solution, which can encourage algae growth.

Syvävesiviljely is known for its simplicity and efficiency. It requires less equipment compared to some other hydroponic methods and can be relatively easy to set up and maintain. The rapid growth rates are a notable advantage, as plants have direct access to water, nutrients, and oxygen. However, it's important to monitor the nutrient solution's pH and concentration regularly to ensure optimal plant health. Common crops grown using syvävesiviljely include leafy greens like lettuce and spinach, as well as herbs.
