Voodoo Juice Bacterial is one of the bacteria-based products; it consists of five species of beneficial bacteria. Voodoo Juice will focus only on roots using their ability to create symbiotic relationships with fungi and beneficial bacteria. Advanced Nutrients’ Piranha, which contains fungi beneficial to plants, is recommended as an ideal companion to our product. Just one litre of Voodoo Juice contains as many as 50 billion bacteria that convert plant nutrients into bioavailable forms. One of these five bacteria is also a nitrogen fixer. Plants treated with Voodoo Juice have been shown to develop about 90% more roots.
