Cellmax Perlite Premium 10-litre Soil Improver
Natural potting soil improver for an airy soil structure and healthy root development. Cellmax Perlite Premium improves the water-air ratio in the soil and is suitable for potting soil, hydroponics and open-field cultivation. Cellmax Perlite is a natural potting soil improver with which you add more air and structure to potting soil or another substrate. Perlite is volcanic rock that expands significantly when heated. This creates light, porous granules that create space between the other components of the potting soil. This open structure ensures that air reaches the roots more easily and excess water can drain away better. This prevents the potting soil from compacting quickly or remaining too wet for long periods. A good balance between water and oxygen supports the development of strong roots and root hairs.
