Red Volcanic Rocks
Volcanic Rocks are rich in iron, magnesium, nitrogen and other minerals which are excellent for healthy succulents. The jagged and irregular edges of Volcanic Rocks create gaps within the potting media which enhances air circulation, drainage and porosity. Pumice
Porous and breathable. Pumice provides excellent drainage and air circulation for the roots. It’s high water absorbancy helps absorb excess moisture within the media preventing root rot. It does not break down easily over time, thus reducing the need to repot the plant frequently due to caking of the media. Green Zeolite
The mineral contents of the Green Zeolite helps in improving soil conditions such as the  water retention and fertility retention. Green Zeolite contains a variety of elements, active substances, and it can help to control harmful bacteria and viral substances in the soil. It also increases the disease resistance of plants and is a popular media used within a succulent potting mix. Medical Stones
The minerals within the medical stones can effectively improve the soil quality and promote the growth of succulents. The surface of the medical stones are filled with pores making it water-permeable and air-permeable, hence improving the airflow and drainage of water.
