Expanded Clay or LECA (lightweight expanded clay aggregate) is an excellent growing medium which can be used in aquaponic farming, hydroponic growing systems, and conventional soil-based agriculture too.
Comes in 1L and 5L options of expanded clay balls
Clay balls range from 8mm-16mm in diameter
Packaged in cardboard (to reduce plastic waste)
Easy to use and mess-free
Inorganic and inert
The surface of the clay has tiny holes all over its surface. This allows better root aeration and increases the available surface area for nitrate crunching bacteria to grow (perfect for aquaponic systems).
The nutrient water will dry out before the nutrients have the chance to turn to algae.
Best used in our Hydropot series, but also a suitable medium for use in flood and drain or nutrient film technique hydroponic systems.
Note: Requires an initial wash to rinse clean. Soak for a few hours and stir around before draining.

This is the first time I’m using this type of product and so far I’ve been happy with the results. The plants are surviving.
Honestly I was a bit skeptical this product, but I really loved it using it with hydro plants and a plant topper to prevent pests does the trick. Would 100% reccommend.
Seem to be helping my orchids and air plants - they are all flowering! The also look great in pots
Still very new with this medium, so far having fun experimenting it as a toper, at the bottom of soils and for hydroponic plants . Will definitely purchase when running low
It s good quality and easy to use.
