Product Description
LECA--Hydroponic LECA Growing Media
LECA(Lightweight expanded clay aggregate) or also knowns as pH balanced expanded clay. These expanded shell pellets form a porous growing medium averaging 816 mm in diameter. Perfect for use with aeroponic and hydroponic gardens, including ebb and flow tables and systems that use grow cups to upport plants. It is also use as decoratives for pot plants.
Garden Clay Pebbles:
Lightweight Expanded Clay pebbles is a great growing medium for all plants. It provides excellent drainage as well as moisture retention. Use it as a decorative mulch for potted plants, in ground plants, as anadd mix to containers, and as a bottom layer for drainage. It is also widely used in hydroponic growing and is
pH neutral. The pores in the stones store water and release water when required therefore providing an
excellent environment for root development. Ideal for roses, orchids and all types of fruits and vegetables
Light expanded clay aggregate, also commonly referred to as "grow rock", is ideal for indoor hydroponic
growth because of its neutral properties - Garden clay pebble has no acid or alkaline characteristics.
( 1 ) With developed Surface pore and specific surface area, ceramsite filter material is suitable for all kinds of microbial growth, also the stable and highly active biological membrane in its surface can handle water with high quality.
( 2 ) Take the advantage of regular shape, density moderate, easy to back flush, low energy consumption, back flush do not lose material, ceramsite filter material can overcome the disadvantage of big flow resistance and easy to cause oxidation pond jams andstrong back flush strength and scour broken easily of irregular granular filter material.
( 3 ) With void distribution uniform of precoat, ceramsite filter material can overcome the shortcomings of serious loss and frequent plugging or harden of water caused by non-uniform distribution of pore of filter material layer.
( 4 ) With good use of size grading, ceramsite filter material has strong assimilative capacity and high filter material utilization ratio and wateread loss increase slowly and also with long operation cycle and big water yield.
( 5 ) Ceramsite filter material has compressive strength resistance to friction, high stability of physical and chemical and long service life, etc. Made of inorganic inert material under high temperature, it will not release any material to water to produce secondary pollution even soak for a long time.

What makes it good for hydroponics?
The properties of LECA are highly attractive to hydroponic gardeners; it is inert, can be used multiple times and is also pH neutral. As it is made up of hard, porous pellets it also enhances the levels of oxygen the plants are exposed to and drains well in hydroponics systems.
LECA also provides a number of distinct benefits:
- The high oxygen levels and improved drainage provided by LECA can help to prevent root rot.
- It helps to conserve water and is ideal for hydroponics systems due to the fact that it drains quickly.
- Gives roots a solid foothold so that they can become secure.
- It can be recycled multiple times making it very cost effective.
- Can be easily sterilised if transferring plants or starting a new project with existing materials.
- The main disadvantage is that LECA doesn’t hold moisture as well as more absorbent mediums, such as coco-coir, although this can be combated by combining it with other mediums
