3 types of hydroponic systems

Here are some hydroponic systems, Drip System, Water Culture, Aeroponics, and Wick.


  • Drip system- a timer controls a submersed pump. The timer turns the pump on and nutrient solution is dripped onto the base of each plant.
  • water culture- the platform that holds the plant is usually made of Styrofoam and floats directly on the nutrient soil. an air pump supplies to the air stone that bubbles the nutrient soil and supplies oxygen to the roots of the plant.
  • aeroponics- the roots hang in the air and are misted with nutrient soil. The misting are usually done every few minutes.
