B.A.C. Lava-Soil is a special substrate treated with our “Final Solution” formula, which promotes a beneficial symbiosis, resulting in a high quality substrate for plant cultivation. This substrate stands out for providing an optimal growing medium, improving both the quality and speed of plant growth. The distinctive feature of our substrate lies in its enrichment with natural lava, which is rich in a wide range of essential nutrients. This addition of lava gives the substrate a porous and aerated structure, favoring air circulation and proper water drainage. As for its technical specifications, the substrate has an electrical conductivity (EC) of 1.4 mS/M and a neutral pH of 6.5, which makes it ideal for the healthy development of plants.
