One compressed brick that expands into a whole bucket of living growing medium. The BioNova coco brick is pre-washed and buffered, so it is ready to use as soon as the water has been absorbed: no salt residues and no guessing about starting values.

With 4 - 5 litres of warm water, the brick expands to about 10 litres of RHP-certified coco fibre. The structure is airy and water retention is even, so the roots get moisture and oxygen at the same time. The neutral pH and low starting EC make it easy to combine with any nutrient line, on its own or mixed with perlite.

The compressed form saves storage space and is light to transport: the same amount of growing medium fits in a bag on the way home. Suitable for indoor growing, greenhouses, pots and the seedling stage.
