What is Expanded Clay?

LECA (Light Weight Expanded Clay Aggregate, Expanded clay pebbles) is made from 100% natural clay at average 1200 degree  in rotary kiln,

the Yielding gases are expanded by thousands of small bubbles as long as this temperature and porosity will appear by many voids and honeycombs

at these round shape aggregates when melted materials become cold. 

 Main sizes of expanded clay

 1) Expanded Clay ~ 2-4mm                                                                    2) Expanded Clay 4-8mm

     3) Expanded Clay 8-16mm                                                                4) Expanded Clay 10-30mm

How To Use Expanded Clay?

1. Rinse expanded clay pebbles to remove excess dirt and debris.

2. Fill plant container with clay pebbles.

3. Sprinkle seeds over clay pebbles directly or transplant seedlings into system.

    You can often find that new transplants are started in rockwool.

4. Fill the reservoir with a nutrient enriched solution following the product’s specifications.

    Empty your reservoir and refill with new nutrient solution approximately every two weeks.

    You may have to refill your reservoir more frequently depending on your plant’s nutrient consumption.

5. Set your timer to flood your plant container a couple times per day. If your system is using a combination of clay pebbles and another type

    of growing medium you may have to adjust the frequency of flooding as some materials hold water more readily than clay.

Lastly, make sure your water drains before reaching the upper surface of your clay pebbles as this can encourage algae growth and can cause issues with plant growth.
