House & Garden Roots Excelurator is the most powerful root product currently available. It is our showpiece in the area of nutrients! This powerful root nutrient ensures explosive growth of the roots, rids the plants of brown root & root diseases and provides an excellent rhizosphere (root environment) in soil, coco or hydroponic substrates. Roots Excelurator creates a film around the roots, which functions as a kind of membrane. It keeps harmful diseases and pathogens out of the root zone but allows ultra-efficient absorption of nutrients.
