The Arlita (expanded clay) is a type of porous substrate for hydroponics (it is suitable for recycling).It is composed of aggregate clay forming balls of more or less 8 and 16mm.
Arlita 3L has a pH stabilized between 5.5 and 6.5, which makes it an excellent support for hydroponic cultivation.It can also be mixed with other types of substrates.The expanded clayballs does not absorb water for a long time, which means that in hydroponic farming does not have a very high safety factor in case the timer or irrigation pump fails.
Tip: Dip the arlite or expanded clay balls into the nutrient solution 24 hours before transplanting to stabilize the pH.
