Rhizoflora® Purpinator®, Purple Plant Pigment Enhancer, 0-2-4, Terpene & Resin Enhancer (1 Quart) Designed to help enhance the expression of purple in capable cultivars, Purpinator® feeds to help support the increased production of flavonoids (plant pigments) and maintains a neutral plant cell pH. Like Terpinator®, Purpinator® provides the building blocks for secondary metabolites, which helps increase the production of terpenes for improved aromatics and flavors. Use alongside General Hydroponics® nutrients or any feed regimen, whether growing hydro, in soil, or with soilless media. How it works Transports - After application, Purpinator® travels to plant cells in direct contact with the epidermal layer of the plant. Stores - Purpinator® is then stored in plant cells, and pushed into storage with the help of bioosmotic potentiators until ready for use. Builds - Purpinator® helps as a building block for secondary metabolites. Produces - Providing building blocks for secondary metabolites, Purpinator® may increase trichome counts and productivity through the addition of fertilizer.
