Expanded Clay Pebbles
Expanded Clay Pebbles – aka LECA or Hydroton. Expanded Clay Pebbles is a light weight, inert, clay aggregate. It is an organic, sustainable material which is shaped into balls, and then fired in an oven at about 650 degrees Celsius. The little balls then puff up into air filled pebbles 9-12mm in size and are a very unique hydroponic and aquaponic growing medium. Growers love them because they have a good balance between air and moisture, easy to use and reusable for many grows to come.
Available sizes: 5L & 50L
