Herba Iron consists of potassium silicate added to humic acids from vermicompost. This product, if used by roots, stimulates the ability of plants to adapt to extreme stress conditions and considerably strengthens and greenens the aerial part of the plant.

Applied via the leaves, herba Iron absorbs moisture and hardens the leaf epidermis and the humic acids present in the solution improve its absorption.

Why buy Herba Line products?

Because since 1983  our company has been extracting humic acids from the  vermicompost  obtained from its own earthworm farm of the Eisenia Foetida family, through cold extractions and very long procedures. Advanced extraction techniques, developed by our company, which allow not to alter the precious bacterial and enzymatic microflora typical of earthworm humus. An Italian product of excellence.
