Lightweight Expanded Clay Pebbles or better known as LECA is definitely a personal favourite for hobbyists and home system owners.  type of growing media. This popular aggregate is lightweight but still provide the plants with the support they need.

LECA is highly porous to create the perfect environment for bacteria due to its ability to retain water and assist in aeration. We recommend using clay balls that are between 9-16mm.

One downside to this type of grow media is that the initial expense of purchasing LECA is quite steep. However, we like to look at it as an investment. LECA is non-degradable, reusable and is worthwhile for crops including ginger and galangal.
