Leca®

Leca

Leca® is a Lightweight Expanded Clay, formed by the heating and firing of clay in a rotary kiln, at temparatures of up to 1150°C. The process transforms the clay into various lightweight ceramic granules, which have a hard ceramic shell and a porous core.

Leca® is the world leader in horticultural, agricultural & hydroponic substrates and your first choice in lightweight building aggregates.

Intact Granules

  • Higher insulation (more closed pores)
  • Better drainage (bigger gaps between granules)

 

Fragmented Granules

  • Better moisture retention (more open pores)
  • Better soil aeration (promotes healthy bacterias)
  • Increases root biomass (sharp edges split and induce exponential root development)
