Hydro Rokz is made from pure, salt-free, baked clay granules. These clay balls are ideal for use in hydroponics.

The clay balls can be placed at the bottom of the pot or mixed into the substrate for better aeration. Optimal oxygenation of the substrate is necessary for good root development.

You can also grow directly with Hydro Rokz in combination with an oxygen pump. The roots are in constant contact with water mixed with liquid fertilizers and the pump provides the necessary oxygen for the roots. In hydroponics, the clay balls and the nutrient solution in water are the perfect combination for a good supply of oxygen to the entire plant.

It contains a very low concentration of elements. The quality of the clay is largely determined by its pH. Hydro Rokz is of the highest quality and has the RHP seal.

What does it mean that Hydro Rokz substrate is RHP certified?

The RHP quality seal is the Dutch RHP standard for horticultural substrates that ensures strict quality control that will give you extraordinary results.
