sera Professional floreground leads to ideal aeration of the bottom ground, and the bottom filtration is maximized. Due to its consistency, it prevents zones in which dangerous rot gases form.
This protects the sensitive plant roots against severe damage. The decorative soil placed on top (e.g. sand or gravel) will last considerably longer.
Placing under the substrate allows roots to establish around the Floreground, giving it higher aeration, more room for growth and a healthier looking plant.
