LECA - Light Expanded Clay Aggregate Growing Medium - Leca Red 8-16mm granules
Regular price R14.00 Save Liquid error (product-template line 117): Computation results in '-Infinity'%Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a light weight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure. LECA has an approximately round or potato shape due to circular movement in the kiln.
Leca® is the world leader in horticultural, agricultural & hydroponic substrates. The benefits of Leca are :
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)
Manufactured to relevant ISO standards, Leca® is consistent in nature:
- pH neutral
- stable & durable
- anti-fungal
- resistant to insects
