Bioactive volcanic substrate 2kg Sub Stratum EXO TERRA

Sub Stratum is a natural volcanic bioactive substrate originating from the Aso volcano in Japan. This type of substrate is very rich in minerals, which makes them great for breeding, plants grow much faster than in a standard substrate.

The substrate is in the form of fine granules, thanks to which it works as:

• independent substrate for plants (3-5cm) stimulating the strong development of nitrifying bacteria and the decomposition of dead organic
• as drainage to remove excess water from the upper layer of the substrate
• as an element of a mixed substrate enriching with minerals and beneficial bacteria

Composition: natural volcanic soil (Andisol), activated carbon, live bacterial cultures
