Expanded Clay 8-16mm 10L
SUST0055
Porous substrate for hydroponic cultivation (suitable for recirculation). It is composed of clay added to form balls between 8 and 16 mm. The internal structure is porous, absorbing and releasing water with nutrient according to the needs of the plant. It is clean, does not decompose and is free of diseases and parasites.
It has a stabilized pH between 5.5 and 6.5 which makes it an excellent support for hydroponics. It can also be mixed with other substrates.
The expanded clay does not absorb water for a long time, which means that in hydroponic cultivation it does not have a very high safety coefficient in case the timer or the pump fails. irrigation.
Submerge the expanded clay in the nutrient solution 24 hours before transplanting to stabilize the pH.
