Only products of the Bio Hesi line are biological. These meet all requirements for biological and organic cultivation, and can be recognised by the "Bio Hesi" name with the corresponding "100% natural", "vegan" and "organic farming" logo's.
The raw materials used in products of this line are sustainably sourced from byproducts of food production, and 100% vegan.
Besides these, Hesi Bio products do contain minerals and trace elements as well. Plants simply need these to survive. While these components technically can't be considered to be organic (in the same way that plain table salt can't be seen as such either), Bio Hesi's ingredients do meet all requirements to be fully permitted for organic and biological farming. The magnesium/calcium salts, as well as all the phosphates and trace elements naturally occur in soil and compost.
