Rhizoflora Purpinator Purple Plant Pigment Enhancer (1 Gallon)
Best additive for growers seeking enhanced color, aroma, and resin production.
Rhizoflora Purpinator is a specialty nutrient additive designed to enhance flavonoid, terpenoid, and resin production in plants. It effectively boosts purple coloration in capable cultivars by regulating cell sap pH, leading to increased trichome and terpene development. This formula improves aromatics, flavors, and potency without plant growth regulators or heavy metals. Purpinator is applied as a root drench and can be integrated into any feeding schedule. For optimal color expression, consider combining with supplemental blue light treatments.

Know before you buy
Purpinator enhances purple coloration only in cultivars that are genetically capable of producing anthocyanins. It works by regulating cell sap pH to help express these natural pigments, but it cannot force a plant to turn purple if it lacks the genetic predisposition.
Yes, Purpinator is designed to be compatible with any existing feeding schedule. Because it has an NPK ratio of 0-2-4, you should account for the added phosphorus and potassium when calculating your total nutrient concentration.
Beyond color enhancement, Purpinator is formulated to boost the production of flavonoids, terpenoids, and resins. This leads to improved aromatics, flavor profiles, and overall potency in the final harvest.
Yes, Purpinator is suitable for soil, coco coir, and hydroponic setups. As a liquid concentrate applied via root drench, it is formulated to integrate easily into various irrigation and delivery systems.
No, Purpinator does not contain any plant growth regulators or heavy metals. It relies on a mineral-based formula to support the plant's natural metabolic processes.
The usage rate increases as the plant matures: use 2-5mL per gallon during the vegetative stage, 6-15mL per gallon during early bloom, and 20-30mL per gallon during late bloom.
