100% Organic. Advanced Nutrients Voodoo Juice contains 5 strains of beneficial bacteria (every liter contains 50 billion microbes) that colonize the plant's root system facilitating the conversion of nutrients. Nutrients are converted to forms that become bio-available to the plants while also stimulating explosive root growth. Plants are better able to acquire vital nutrients and moisture, which massively enhances plant growth. In testing, root mass has been found to increase over control plants as much as 90%. Not a mycorrhizal mixture.
