Description
VOODOO JUICE 4 LITRE is Advanced Nutrients’ flagship beneficial bacteria inoculant — one of the most researched and most consistently effective root-zone microbiome products in the professional growing market. We have been recommending Voodoo Juice to UK growers since 2017 because the science behind beneficial bacteria in the root zone is compelling and well-documented, and the results growers report with Voodoo Juice in DWC, coco, and soil systems are consistently impressive.
The Science Behind Voodoo Juice
Voodoo Juice contains multiple strains of plant growth-promoting rhizobacteria (PGPR) — specifically selected bacteria that colonise the root surface and rhizosphere, producing a range of compounds that directly benefit the plant. These include indole-3-acetic acid (a natural auxin that stimulates root elongation and lateral root branching), siderophores (iron-chelating molecules that improve micronutrient uptake), and volatile compounds that trigger the plant’s own root-growth response pathways. The practical result is root systems that are measurably larger, denser, and more prolific than those grown without beneficial bacteria — and larger root systems absorb more water and nutrients, which translates directly to faster vegetative growth and heavier flowering performance. The 4-litre size is the choice of serious growers who use Voodoo Juice consistently across multiple cycles.
How to Get the Most From Voodoo Juice
Apply Voodoo Juice from the first watering after transplant or when moving rooted cuttings into their final growing medium. Use at 2ml per litre for the first two weeks to establish the bacterial colony in the root zone, then reduce to 1ml per litre as a maintenance dose through the vegetative phase. Voodoo Juice is compatible with most nutrient systems and growing media, but avoid using in combination with heavily chlorinated tap water or high-concentration fungicide applications that could kill the live bacteria cultures. Store opened bottles in the refrigerator to extend shelf life between uses.
Pair Voodoo Juice 4 Litre with Tarantula (beneficial fungi) and Piranha (beneficial bacteria and trichoderma) for the complete Advanced Nutrients root inoculation programme that builds the most productive root zone possible.
