This block of compressed coconut results into 10litres of ready-to-use coconut substrate after adding 3 liters of water to it. Furthermore, its volume will increase approximately tenfold. As a result of its initial size, the substrate is fairly easy to transport. Compared to regular peatsubstrate (potting soil) coconut substrate has a great number of benefits, which are: It is easy to use, it has the low EC value of < 0.4 mS/cm, it has the ideal Ph value of 5.8, it stimulates a perfect root development, the coco substrate is not compact which makes it easy to drain, it is a light product: 85 kg/m3 (peatsubstrate weighs 125 kg/m3), coconut has a good and swift waterabsorption, coconut substrate can be re-used and the use of coconut often leads to a higher yield compared to other substrates. This substrate is thoroughly washed out and treated for diseases, vermin and weeds. Moreover, it contains special additives in order to assure a top result. Comes in a pack of 6 x 10litre bricks.
