For all growing methods: hydroponics and soil
PRO Roots is a growth and bloom activator

It stimulates the development of micro organisms in the root mass and promotes the growth of roots and rootlets.
It improves the roots biotope and hardens the root cap. This activates the development of a vigorous root mass and a better settlement of the plant in its environment.
It allows better resistance to disease and pathogenic moulds (powdery mildew, dumping off in seedlings and cuttings, etc).
