Pentakeep is the only product in the world that contains 5-aminolevulinic acid. This promotes photosynthesis, whereby the plant produces more dry matter and so therefore stimulates the growth of plants and flowers.

Pentakeep is a liquid nitrogen fertilizer to which 5-aminolevulinic acid has been added. This amino acid promotes photosynthesis. 5-aminolevulinic acid is an important amino acid for the plant; it plays an important role in the formation of chlorophyll (leaf green). The fertilizer mix Pentakeep includes nitrogen, magnesium and trace elements. It has been proven that these nutrients in conjunction with 5-aminolevulinic acid have a strengthening effect on the growth of plants.
