Expanded Clay (Arlita) 10L has a stabilized pH level between 5.5 and 6.5, which makes it an excellent support for hydroponic crops. We also recommend using it by mixing it with other types of substrates.
The expanded clay does not absorb water for a long time, which means that hydroponic crops do not have a very high safety factor in case the timer or irrigation pump fails.
Clay is a type of porous substrate for hydroponic crops. It is composed of compressed clay forming balls of between 8 and 16mm.
The inner part of the clay is porous, absorbing the water with nutrients and releasing it to the needs of the plants. The arlite is a clean substrate that does not decompose, is free of diseases and parasites.
Tip: Dip the expanded clay balls into the nutrient solution 24 hours before transplanting to stabilize the pH.
