Deep water culture, which I will refer to as D  WC from here on out, is hands-down the easiest type of hydro system to use.​

How  DWC works:-

  • In a DWC system, you use a reservoir to hold a nutrient solution. The roots of your plants are suspended in that solution so they get a constant supply of water, oxygen, and nutrients.
  • To oxygenate the water, you use an air pump with an air stone to pump bubbles into the nutrient solution. This prevents your roots from drowning in the water — a weird thing to think about, but it can (and does) happen to many beginner hydroponic gardeners.
  • Your plants are typically housed in net pots that are placed in a foam board or into the top of the container that you’re using for your reservoir. With some hydroponic growing media added into your net pots, they provide a home for the very beginning of your root system and plant stems.​​

Benefits of Deep Water Culture :- 

  • Very inexpensive and easy to make at home.
  • Extremely low-maintenance.
  • Recirculating, so less wasted inputs.

Downsides of Deep Water Culture:-

  • Does not work well for large plants.
  • Does not work well for plants with long growing period.
