Expanded clay balls are pellets of inert clay that have been fired to create small marble-sized balls that can be used in hydroponic growing systems. Also sometimes known as LECA (lightweight expanded clay aggregate) or hydroton.



Specifications

  • Clay balls range from 8mm-16mm in diameter
  • Packaged in cardboard (to reduce plastic waste)
  • Easy to use and mess-free
  • Neutral pH
  • Inorganic and inert
  • The surface of the clay has tiny holesĀ all over that allow better root aeration and increase the available surface area for nitrate crunching bacteria to grow (perfect for aquaponic systems).
  • The nutrient water will dry out before the nutrients have the chance to turn to algae.

Good value

Worked really well with my indoor plants in one of my hydroponic pots. There was a really large amount in a nice cardboard box. Would definitely buy again.
