Most soilless substrates are natural nonrenewable resources which involve environmental damage. The CompoCharTM is a biochar growing substrate, made locally from wood wastes and composted sewage sludge. The CompoChar has available macro and micro elements, a great balance between water holding capacity, drainage, and aeration. In addition, 1 ton of CompoChar locks 1.2 ton of atmospheric CO2.
