Van Iperen CalMag Iron Horticultural Grade is a derivate of Calcium and Magnesium Nitrate. The product is recognizable by its unique flake shape which is easily soluble with record solubility levels.
Combining Calcium and Magnesium with Nitrates is useful to promote healthy vegetative growth, strong fruit setting and qualitative fruit growth. This is achieved thanks to healthy cell walls and high chlorophyll production.
In addition, the product contains chelated Iron which brings an extra boost to chlorophyll production.
Van Iperen CalMag Iron Horticultural Grade is recommended from early flowering and until end of fruit growth stages.
