Five Types of Hydroponic Growing Systems

There are many different types of hydroponic growing systems. Some of the most common include wick, reservoir, drip, and aeroponic. Each type of system has its own advantages and disadvantages. This article will discuss some of the most common types of hydroponic growing systems.

Wick

One of the first types of hydroponic growing systems is the wick variety. Wick systems are the simplest type. The type of system uses a wick to draw nutrient solution into the growing medium. These hydroponic growing systems can use different growing mediums such as Vermiculite, coconut fiber, and Perlite. The main disadvantage of the wick system is that large plants may use more solution that the wick can supply.

Ebb and Flow

Ebb and flow systems are commonly referred to as flow and drain systems. These hydroponic growing systems flood the growing tray with nutrient solution then drain it back into a reservoir. This is usually accomplished by a timer that is connected to a pump. The main disadvantage of these hydroponic growing systems are that they are susceptible to timer and pump complications. If the roots aren't given nutrient solution for a while, they will quickly dry out.

Drip

Drip systems are the most common type used. These hydroponic growing systems use a pump controlled by a timer to release solution. Once released, the solution goes through a line that drips it onto the base of each plant. Some drip systems recycle excess solution, while others don't. The hydroponic growing systems that recycle the solution can experience shifts in the pH and nutrient levels, so they require more maintenance.

Reservoir

The reservoir system has a Styrofoam platform holds the plants. This platform floats directly on the nutrient solution. These hydroponic growing systems also have an air pump connected to an air stone. This air stone is responsible for producing the bubbles that supply oxygen to the roots of the plants. These hydroponic growing systems don't work well with large plants, so they are commonly used for plants that grow fast and require a lot of water like lettuce.
