Type 2 The water culture system is the simplest of all active hydroponic systems. The platform that holds the plants is usually made of Styrofoam and floats directly on the nutrient solution. An air pump supplies air to the air stone that bubbles the nutrient solution and supplies oxygen to the roots of the plants.

Type 3 The Ebb and Flow system works by temporarily flooding the grow tray with nutrient solution and then draining the solution back into the reservoir. This action is normally done with a submerged pump that is connected to a timer.

3 advantages and disadvantages
Disadvantages of using a soilless system include having to maintain the balance of nutrients in the solution, pH monitoring, pump maintenance, and a high initial cost. These disadvantages are being overcome with automation, human ingenuity and commercialization.
