Can LECA Clay Pebbles be Boiled?
Many people, myself included, want to reuse their LECA and want to know how best to clean them. So, can LECA be boiled?
The simple answer is yes, you can safely boil LECA (Lightweight Expanded Clay Aggregate). LECA is considered inorganic potting media, just like lava rock, perlite (also known as sponge rock), pumice, rock wool, hydroton, Growstone, stones & pebbles and several other types of media, and can be boiled safely. Doesn't it look like I'm cooking black beans? 😜
Write something about yourself. No need to be fancy, just an overview.
