The Bacillus subtilis plant growth is a high-quality liquid that will help to increase the number of roots and stems of plants and will encourage faster plant growth.The Bacillus Subtilis plant growth is a mix of two bacteria strains that work together to help plant roots to grow more and more robust. These bacteria strains are B. subtilis and B. amyloliquefaciens. B. subtilis helps plant roots to increase their intake of nitrogen and B. amyloliquefaciens helps plant roots to increase their uptake of phosphorus.
