Hydrotons/LECA - 2.5 Litre Pack

LECA/ Hydrotons /Clay Ball

Lightweight Expanded clay aggregates (LECA) are porous ceramic products with a uniform pore structure of fine, closed cells and with a densely sintered, firm external skin. It is manufactured in rotary kilns from raw materials containing clay minerals. The raw material is prepared, moulded and then subjected to a firing process at temperatures of between 1100 and 1200 ºC, resulting in a significant increase in volume due to expansion. The LECA grains internal cellular structure with thousands of air-filled cavities helps plant roots to develop faster and strong.

Key Features 

·         Water Retention & Drainage - This material is filled with tiny pores, much like a ‘micro sponge’. Because of this, it holds the perfect amount of water and drains any excess to prevent overwatering.

·         Aeration – Unlike soil that compacts and reduces available oxygen over time, hydroton retains its shape and allows for continuous oxygen exchange, keeping your plant roots healthy.

·         PH Neutral – In gardening, it is important to have a growing medium that isn't too acidic or basic. This material is a pH neutral product, so you won’t have to worry about any nutrient lockup or plant health issues due to unstable pH.

·         Sterile – It is produced in large rolling kilns that ‘bake’ it into its final shape. Since high temperatures are used, hydroton comes to the gardener as a sterile product. This is highly beneficial because you don’t want to introduce disease and harmful bacteria into your garden.
