Pack of 40s, Biochar sponges, biodegradable growing media

40pcs of biochar per pack

Biochar stands out by its extremely porous structure. Because of this characteristic, Biochar is able to absorb five times as much of its own weight of water and its dissolved substances.

Another advantage of Biochar is its great cation exchange capacity (CEC), which is due to its porosity. The CEC is a measure of soil science and describes the ability to store positively loaded ions on the surface and, as a result, make it available again for plants and micro-organisms.

A high CEC-Value secures that less mineral and also organic nutrients from the soil are washed out, leading to a higher availability of nutrients in the ground.
