The auxiliary material (also called aggregate or additive) made from the natural rock perlite is used in professional indoor cultivation for mineral soil improvement. Potting soil can increase the volume of water storage through the added rock, is optimally ventilated and has a more stable structure. A garden with a mix of potting soil and insulation material is the perfect breeding ground for all plants that need a well-ventilated substrate as a basis for optimal root growth, such as roses, tulips and vegetables.
