Static Solution / Deep Water Culture

Static Solution and Deep Water Culture systems are very similar so I will discuss both of these in this post

Static Solution System

Static Solution is one of the easiest homemade hydroponic systems that you can build.

Basic Design

The basic components of a Static Solution Culture system are a  reservoir and optionally an air pump with an air stone to aerate the nutrient solution.  The lid of the reservoir has holes drilled into it and the plants are suspended through the holes with their roots only very slightly suspended into the nutrient solution.  The plants are generally placed in pots filled with aggregate  to hold them in place.

With this method you can simply have one plant growing in a mason jar or any other conatiner with a lid that you have around the house.  A vase or other stylish container can be used, it’s really easy so give it a try.

Design Considerations

There are a few things to keep in mind when you design your Static Solution hydroponic system

  • The nutrient needs to be kept in a dark reservoir to stop algae growing, you can paint the outside of the container to stop light getting in
  • Ensure that the roots are only just in the nutrient to stop the roots from rotting
  • You will need to refresh the nutrient solution

Deep Water Culture (DWC)

Deep Water Culture (DWC) is another easy homemade hydroponic system that you can quickly build

Basic Design

The basic components of a DWC system are a  reservoir, an air pump with an air stone to aerate the nutrient solution.  The lid of the reservoir has holes drilled into it and the plants are suspended through the holes with their roots suspended into the aerated nutrient solution.  The plants are generally placed in a net pot to hold them in place.

Design Considerations

There are a few things to keep in mind when you design your DWC hydroponic system

  • The nutrient needs to be kept in a dark reservoir to stop algae growing, you can paint the outside of the container to stop light getting in
  • The plants require air around the roots to stop the roots from rotting
  • You will need to refresh the nutrient solution

I have located the following YouTube video which demonstrates building a DWC system.  In the video a system is built for propagating plants, simply up size the reservoir for normal plants.

Please refer to the Vegetable Growing Guide for the required nutrient concentration to place into the reservoir.
