Light expanded clay aggregates are made by heating the clay. As the #clayballs heat up, they fill with bubbles and form into small marble sized balls.Irregular in size - these clay pebbles are the most favorable medium for drain systems.

Benefits : 

• They are best at retaining moisture. 
• They are great for water drainage
• These light weight and porous balls hold air in them and increases the aeration for the root system of the plant. 
• Leca balls are reusable
• Since the Leca only wicks water up to the plant when it is needed and this means the time between the watering is extended. 

How to use :

• Rinse the clay balls with water & repeat the process until the leftover water is clean.
• The clay balls are covered with dust and it can cause clogging hence it is advisable to clean it outside. 
• Once cleaned, soak it for min 24 hrs. Wash again before use.
• Ph water level should be anywhere b/w 5.5 - 6 as it works well with most plants. 
• If you are new to this growing medium, it's best to start with easy to propagate in water / with small plants.
• Ensure you change water once in every 2-3 days. 
• You can use liquid fertilizer at a later stage.

Note : 

*** Leca is just a collection of clay balls & doesn't contain any nutrients. It only takes care of watering your plant.
