Clay Pebbles Vitalink 10L

Porous substrate for hydroponic cultivation (suitable for recirculation). It is composed of aggregate clay forming balls of between 8 and 16 mm. The internal structure is porous, absorbing and releasing water with nutrients according to the needs of the plant. It is clean, does not decompose and is free of diseases and parasites.

It has a stabilised pH between 5.5 and 6.5, which makes it an excellent medium for hydroculture. It can also be mixed with other substrates. Expanded clay does not absorb water for a long time, which means that in hydroponics it does not have a very high safety coefficient in case the timer or irrigation pump fails. Soak the expanded clay in the nutrient solution 24 hours before transplanting to stabilise the pH.

It is also widely used to put in the bottom of the pot for better drainage and to avoid waterlogging of the pot.

The clay balls allow great aeration and perfect drainage. It contains a highly porous structure derived from expansion at high temperatures. It retains 15-20% of its weight in water. When mixed with substrates, it increases their porosity and provides aeration. It is also highly appreciated as a decorative element placed on the surface of pots and planters. It is an unalterable material that is free of germs, thus achieving the natural suppression of weeds. Clay balls are clean, light, decorative and easy to handle.
