From this I can only potting soil each drindend abraten- She tested only organic soil with greatly increased Cadniumwerten at Eco Test 2012. Cadnium is a poisonous Schmermetall which is absorbed through the plants / herbs from the human organism. It remains an average of 30! Years in the body. Plants store it in root, stem and leaves and blooms. The manufacturer will also violates the law because the earth would have to be labeled as "Cadnium greatly increased". It is simply scandalous that such a health and environmental harmful product wird- sold under "Bio", the manufacturer should be ashamed.
