Green Zeolite 3-5mm
Price range: $30.00 through $32.50
Zeolite is Silicate of potassium, sodium and calcium. It's a volcanic rock with a high cation exchange capacity and water absorption thanks to the high content of "tectosilicatic" minerals such as chabasite and phillipsite. The zeolite for horticultural use has to be imagined as a scaffold; within the spaces of the scaffold the nutrient are slowly released and only under request of the plants.
