In addition to these benefits, Purpinator will improve the coloration of plants with purple phenotypes. Much like its predecessor, Terpinator, Purpinator activates the metabolic pathways for trichome and terpene production in plants by providing the building blocks for these processes. Purpinator will also regulate the pH of the cell sap in plant vacuoles, resulting in a more neutral cell sap pH which yields increased purple coloration expressed in the plant.
