If you don’t have big, healthy, robust root systems, a lot of your growing efforts will prove fruitless. That’s because your plants’ roots won’t be able maximize uptake, so a lot of the nutrients you feed them will go to waste. Now, imagine doubling their root size. Visualize those thick, extensive roots reaching out and sucking up energy and nutrients for vigorous growth – and ultimately bigger yields. 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%!
