Purpinator is an aroma & color enhancement late- bloom finisher. It’s a purpose-built, commercial-ready additives that layer cleanly onto your base program to help elevate late-stage quality—aromatics, color expression, and visual appeal—without overcomplicating your feed.

General Hydroponic’s Purpinator is a first-of-its-kind plant nutrient made for crops that produce anthocyanins. It feeds to help increase terpene and flavonoid production, encourage trichome development, and boost expression of purple pigments in capable genetics—so you finish with heightened aromatics and standout color you can see and smell.

Built to slot into your existing schedule as a targeted additive, Purpinator keeps your program simple while leveling up bag appeal.

 

Purpinator feeds to help encourage terpene and flavonoid production, trichome development, and purple pigment expression in plants with anthocyanin potential.

Use during bloom and late bloom according to the product label. Add to mixed nutrient solution, agitate thoroughly, and check pH and EC before feeding.

Late bloom is when finished quality cues become most visible. Purpinator helps growers support aroma, color, and trichome expression without replacing the base nutrient program.

Usage Guide

Purpinator — How to Use

● When to start: Introduce in bloom and continue through late bloom/finish per
your standard timing.
● How to dose: Add to your mixed nutrient solution (do not add to undiluted
concentrates). Agitate, then verify pH/EC before feeding.
● Program fit: Use alongside your base fertilizer and bloom supplements. Keep
your core recipe; treat Purpinator as the finishing layer.
● Expectation setting: Purple coloration requires genetics capable of anthocyanin
expression; Purpinator supports that potential where present.
● Operational tip: Standardize your late-bloom window across rooms or benches so
staff apply Purpinator consistently with your SOPs.

Grower Benefits

Purpinator — Key Benefits

● Finish with presence: Feeds to encourage increased terpene production for
richer, more noticeable aromatics in the final weeks.
● Color that pops: Helps enhance color and supports anthocyanin (purple)
expression in genetics that can express it—ideal for cultivars where visual impact
matters.
● Quality cues that sell: Feeds to help increase flavonoid production and
encourage trichome production for a finished look consumers gravitate toward.
● Purpose-built for late bloom: Designed to support the final push so crops close
strong without re-engineering your base program.
● Plug-and-play additive: Drop into your current bloom schedule; the format keeps
operations simple while giving your team a clear finishing lever.

Frequently Asked Questions

How should Purpinator® be stored, and what is its shelf life and warranty?

Store Purpinator® tightly sealed in a cool, dry place away from direct sunlight, ensuring average temperatures stay above 40 °F and the liquid does not freeze. Unopened, it remains stable for up to 2 years (and should be used within one year of opening). It carries a 1-year manufacturer warranty conforming to label specifications.

Is Purpinator® compatible with all systems and nutrient lines?

Yes. Purpinator® is a highly soluble liquid concentrate that layers cleanly onto any existing base nutrient program (whether GH-branded or competitor lines). It runs cleanly in commercial fertigation setups, hydroponics, coco coir, and soilless container gardens.

How should Purpinator® be mixed into irrigation water, and will it alter water chemistry?

Always add Purpinator® directly to your already mixed nutrient solution—never mix it with undiluted concentrates. Purpinator® is derived from monopotassium phosphate, potassium sulfate, and magnesium sulfate. While it adds to your overall EC, it is not a pH control product; always agitate the reservoir thoroughly and adjust pH and EC last.

What are terpenes and trichomes, and how does Purpinator® physiologically support them?

Terpenes are natural molecules in plant oils responsible for aroma and taste, while trichomes are the tiny crystal-like structures where these oils are synthesized and stored. Purpinator® provides targeted nutrition that stimulates the biosynthetic pathways responsible for developing these resin- rich structures, improving both the scent profile and visual "bag appeal" of the final harvest.

When should Purpinator® be introduced, and how does it fit into the grow schedule?

Purpinator® is a purpose-built additive designed to be used throughout the entire vegetative and bloom phases of the plant's life cycle. It is a "plug-and-play" additive that slots directly into your existing schedule as a premium finishing layer, meaning you do not need to alter or re-engineer your core base nutrient recipe.

Will Purpinator® turn any plant purple?

No, purple coloration requires genetics that are naturally capable of anthocyanin expression. Purpinator® acts as a facilitator to support and enhance that genetic potential where present, but if a plant variety lacks those specific genetics, it will not turn purple. However, non-purple varieties will still benefit from heightened aromas, flavors, and increased trichome density.

What is Purpinator® and how does it differ from a standard terpene booster?

Purpinator® (0-2-4) is a first-of-its-kind plant nutrient additive engineered to boost crop quality and aesthetic appeal. Beyond increasing terpene and flavonoid production and encouraging trichome development, it is formulated to help increase the natural expression of purple pigments (anthocyanins) in capable plant genetics.
