Leca Production

During the LECA® LWA manufacturing process, the natural clay once treated and dried is passed through a rotary kiln and fired to a temperature of approximately 1150°C. This process expands the clay, fuses and melts to form pellets up to five times the clays original size. The resulting LECA® LWA particle has a hard and resistant exterior skin and a cellular interior. THESE ARE THE PRIME

What is Leca and why is it useful for plants? Plant care

13/04/2020· Leca is an acronym and it stands for: Lightweight expanded clay aggregate. It sounds very complicated, but it's quite easy to explain. Essentially, Leca is a growing medium, like soil, in which you can grow your plants. Leca is a collection of baked clay balls that expand when you soak them in water. Opposed to using soil, Leca is not able to provide nutrients to your plants by itself. So you

The Complete Guide to Leca Indoor Plant Addicts

Due to the manufacturing process leca is extremely porous which aids in its ability to capture and hold oxygen. This is great for your plants roots and helps mitigate the risk of root diseases like root rot. Leca also doesn’t decay or compact over time, which occurs in organic based soils from decomposition. This helps maintain a healthy air flow to the root system and provides ample oxygen
