8-16mm expanded clay pebbles
LECA(Lightweight expanded clay aggregate) or also knowns as pH balanced expanded clay. These expanded
shell pellets form a porous growing medium averaging 8-16 mm in diameter. Perfect for use with
aeroponic and hydroponic gardens, including ebb and flow tables and systems that use grow cups to
support plants. It is also use as decoratives for pot plants.
LECA is a wonderful and ideal replacement of conventional soil for garden plant and follower growth.
Due to thousands of cavities, LECA can deep more water and nutrition than the conventional soil and has better
air permeability and water discharge. So, we only need to recharge water and nutrition one or twice a month for
plants and followers
LECA keeps away from the pollution of conventional soil and is impervious to attack by wet rot and insects. So
it makes it easy to manage the plants and followers.
LECA is a super lightweight particle and let us easy to carry and move the plant and follower containers here
and there.
To prevent any pollution by insects or bacteria, we can clean the LECA by water than boil the LECA one or
twice a year in case we do not want to buy new LECA for replacement.
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 an
add 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.
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 .
