WELGRO® HIDROPONIC is a homogenized and balanced solution of Iron chelate (Fe-DTPA) with Manganese (Mn-EDTA), Copper (Cu-ED TA) and Zinc (Zn-EDTA) chelates; it also contains Boron and Molybdenum. Metallic ions chelated by DTPA or EDTA do not react with other nutritive solution components in both hydroponics or fertigation, so, metallic oligoelements are kept in solution, totally available for the plant.
Also avariable without Boron: WELGRO® HIDROPONIC SIN BORO
