Hydroponic Growing Systems

Hydroponic Growing Systems
Hydroponic Growing Systems

There are six different types of hydroponic growing systems, they are: Aeroponic, Drip, Ebb and Flow, N.F.T, Water Culture and Wick.

  • Aeroponic System: One of the most high tech growing systems
  • Drip System: The most widely used type of hydroponic systems
  • Ebb and Flow System: The system can be modified in many ways
  • N.F.T.: Nutrient Film Technique System – most commonly thought of
  • Water Culture System: A very simple to use hydroponic system
  • Wick System: The simplest of all hydroponic systems

Aeroponic System: One of the most high tech growing systems

Aeroponic Growing System

One of the most high tech growing systems
The growing medium is primarily air
The roots hang in the air and are misted with nutrients every few minutes
A timer must be used to control the nutrient pump to ensure the plants are properly misted with the nutrients

What you’ll need:

Reservoir
Pump and Spray Nozzles
Grow Media
Nutrient Solutions
pH and EC/TDS controller, such as the Hanna HI 2500

Drip System: The most widely used type of hydroponic systems

Hydroponic Drip Growing System

The most widely used type of hydroponic systems
A timer controls a submersed pump that releases a nutrient solution onto the base of each plant
In a Recovery Drip System, the excess nutrient solution is collected and reused
The Recovery Drip System is more sustainable, however the pH and nutrient strength levels may vary because the nutrient solution is reused
In a Non-Recovery Drip System, it does not collect the excess solution
The Non-Recovery Drip System must have a precise timer to ensure that the least amount of nutrient solution is wasted

What you’ll need:

Water reservoir
Pump for fertilized water
Drip manifold and lines
Grow tray and media
Nutrient solutions
Air pump and diffuser
pH and EC/TDS controller, such as the Hanna HI 5000

Ebb and Flow System: The system can be modified in many ways

Ebb and Flow Growing System

This system works by temporarily flooding the grow tray with nutrient solution and then draining the solution back into the reservoir, which is controlled by a submeresed pump on a timer
Several times a day, the timer comes on and allows the pump to release the nutrient solution into the grow tray
When the timer shuts off the nutrient solution is collected back into the reservoir
This system can be modified in many ways such as filling the grow tray with grow rocks or gravel
One main disadvantage of this system is the possibility of a power outage and/or pump timer failures, due to the growing medium that is used

What you’ll need:

Water reservoir
Pump for fertilized water
Grow tray and media
Nutrient solutions
Air pump and diffuser
pH and EC/TDS meter, such as the Hanna HI 9813-6

N.F.T.: Nutrient Film Technique System – most commonly thought of

Water Culture System: A very simple to use hydroponic system

Water Culture Growing System

A very simple to use hydroponic system
A styrofoam platform typically holds the plants and floats on the nutrient soltuion
An air pump is used to supply air to a bubbling stone that releases the nutrient solution and supplies oxygen to the plant roots
Leaf lettuce is the predominant plant grown in this type of system, very few other plants grow well in the Water Culture System

What you’ll need:

Water reservoir
Grow tray and media
Air pump and diffuser
Nutrient solutions
For small scale systems, a pH and EC/TDS Tester, such as the Hanna HI 98129
For large scale systems, a pH and EC/TDS controller such as the Hanna HI 10,000 fertigation unit

Wick System: The simplest of all hydroponic systems

Wick Growing System

The simplest of all hydroponic systems
The Wick System is a passing system, meaning it has no moving parts
The nutrient solution is released into the grow tray through a wick
There are several different growing mediums that can be used in this hydroponic system

What you’ll need:

Water reservoir
Grow tray and media
Air pump and diffuser
Nutrient solutions
pH and EC/TDS testers such as the Hanna HI 98127 and HI 98311
