Voodoo Juice allows growers to double their plant root size. Scientific tests on your high-value crops isolated 11 strains of plant growth-promoting rhizobacteria (PGPR) that help to expand root mass by up to 117%. This in turn increases nutrient absorption by up to 700%! Try it for yourself and you’ll see an enormous difference. You may not see your root mass triple like one grower experienced, or witness meter-long roots like another – and your plants may not double in size, like others reported – but we can ensure your satisfaction with our world-famous Grower Guarantee: Either you love Voodoo Juice and the way it spikes up your yields, or you get all your money back.
