growmediaWhen setting up your Aquaponics system you will find you have a wide variety of Grow Media to choose from. Whatever you decide to use, it must be able to drain well so plants roots don’t get water logged and begin to rot.

Most Aquaponics users, including us use LECA, (Light weight Expanded Clay) Pebbles or Hydroball. They have a high porosity and air content, and are 4-16mm which is best for roots to move easily through. Plus they are light weight, taking strain off your grow beds.

The grow media in an aquaponics system serves several very important purposes:

 

  • Hold the plants in place
  • A home for the beneficial bacteria and worms
  • Moisture retention during the drain cycle
