Types of Hydroponic Systems
“What are the different types of hydroponics systems?”
The best thing about hydroponics is that there are so many different types of systems available. You are certain to find one that suits your needs.
Have a read through these different systems below. It might help you decide which will be best for your grow. And of course, if you have any questions, always feel free to ask us 🙂
Deepwater Culture (DWC), also known as the reservoir method, is by far the easiest method for growing plants with hydroponics. In a Deepwater Culture hydroponic system, the roots are suspended in a nutrient solution. An aquarium air pump oxygenates the nutrient solution keeping the plant’s roots from drowning. Remember to prevent light from penetrating your system as this can cause algae to grow. This will wreak havoc on your system which can be difficult to fix. Any easy solution to this is to ensure you use black hosing for your dripper and feed lines, as opposed to clear or white.
The main benefit of using a Deepwater Culture system is that there are no drip or spray emitters that can become clogged. This makes DWC an excellent choice for organic hydroponics as hydroponics systems that use organic nutrients are more prone to clogs.
Nutrient Film Technique
Nutrient Film TechniqueNutrient Film Techinque, or NFT, is a type of hydroponic system where a continous flow of nutrient solution runs over the plants roots. This type of solution is on a slight tilt so that the nutrient solution will flow with the force of gravity.
This type of system works very well because the roots of a plant absorb more oxygen from the air than from the nutrient solution itself. Since only the tips of the roots come in contact with the nutrient solution, the plant is able to get more oxygen which fascilitates a faster rate of growth.
Aerogarden Aeroponics SystemAeroponics is a hydroponics method by which the roots are misted with a nutrient solution while suspended in the air. There are two primary methods to get the solution to the exposed roots. The first method involves a fine spray nozzle to mist the roots. The second method uses what’s called a pond fogger. If you decide to use a pond fogger then make sure you use a Teflon coated disc, as this will reduce the amount of maintenance required.
You may have heard of the AeroGarden, which is a commercialized aeroponics system. The AeroGarden is an excellent entry point to aeroponics. It’s a turn-key system that requires little setup. It also comes with great support and supplies to get you started.
Hydroponic Wick SystemWicking is one of the easiest and lowest costing methods of hydroponics. The concept behind wicking is that you have a material, such as cotton, that is surrounded by a growing medium with one end of the wick material placed in the nutrient solution. The solution is then wicked to the roots of the plant.
This system can be simplified by removing the wick material all together and just using a medium that has the ability to wick nutrients to the roots. This works by suspending the bottom of your medium directly in the solution. We recommend using a medium such as perlite or vermiculite. Avoid using mediums such as Rockwool, coconut coir, or peat moss because they may absorb too much of your nutrient solution which can suffocate the plant.
Ebb & Flow
Ebb and Flow SystemAn ebb & flow hydroponics system, also known as a flood and drain system, is a great system for growing plants with hydroponics. This type of system functions by flooding the growing area with the nutrient solution at specific intervals. The nutrient solution then slowly drains back into the reservoir. The pump is hooked to a timer, so the process repeats itself at specific intervals so that your plants get the desired amount of nutrients.
An ebb & flow hydroponics system is ideal for plants that are accustomed to periods of dryness. Certain plants flourish when they go through a slight dry period because it causes the root system to grow larger in search of moisture. As the root system grows larger the plant grows faster because it can absorb more nutrients.
Drip SystemA hydroponic drip system is rather simple. A drip system works by providing a slow feed of nutrient solution to the hydroponics medium. We recommend using a slow draining medium, such as Rockwool, coconut coir, or peat moss. You can also use a faster draining medium, although you will have to use a faster dripping emitter.
The downside to a system like this is that the drippers / emitter are famous for clogging. We prefer not to use drip systems, but it can be an effective method for growing if you can avoid the clogs that plague this type of system. The reason the system gets clogged is because particles from nutrients that build up in the emitter. Systems that use organic nutrients are more likely to have this kind of issue.
