Hydro Rokz Cocos 60-40 is a substrate which mixes a 60% of clay balls and a 40% of coconut fiber.
Hydro Rokz Cocos offers a lot of benefits to the hydroponic culture. The clay pebbles give an excellent drain, because they barely retain water. This diminishes the risk of excessive watering. When water is drained, the fresh air gets to the root area and gives this substrate a high air proportion for an optimal root development.
Adding coconut augments the substrate's water retention. Coconut offers a regulator between water times, because it ensures the humidity levels near the roots are stable.
