Potting soil

Potting soil is used for growing plants. Most potting soils contain fertilizers, which allow plants to grow in potting soil for the first few weeks without additional fertilizer. What you may not know is that animal waste products are added to almost all potting soils as fertilizer. We do this completely differently at Cellmax. Cellmax guarantees that no animal raw materials are used for all products. We like that better.

A substrate is an artificial soil for plants that gives firmness to the roots. Because substrates do not contain nutrients, they are added from the beginning of the cultivation process. Substrates can be made from all kinds of materials, often also from non-natural materials such as rock wool. Cellmax substrates are actually made from natural materials such as coconut and clay.


Our Coco mixes are made from coconut husks. They are 100% peat-free and reusable products. Strictly speaking, they are substrates, but because they are very similar to potting soil in use, they are often simply referred to as potting soil.

Coconut retains water well and therefore has a good buffering capacity: nutrients are gradually absorbed. You can choose from two types of Coco mix: the standard mix and the mix with perlite. The latter has an extra airy structure, which ensures a perfect water balance and more oxygen for the roots.
