Who This Is For

  • You are adding a finishing supplement because your harvest genetics are not hitting their full visual potential.
  • You are integrating a cellular pH balancer because acidic environments are muting the pigments in your crop.

What We Found

  • We find this works best when you already have your base nutrients dialed in and just need that final push for color.
  • The way this maintains neutral cell pH is the real secret to unlocking those deep pigments late in the cycle.

What Users Say

  • Growers who switched from Terpinator say they kept the same aromatic punch while finally seeing those deep purples.
  • Buyers report that adding this to a standard hydroponic setup helped them hit higher price points for bag appeal.

General Hydroponics Purpinator

Genetic potential means nothing if your plants lack the nutritional support to fully express their phenotypic characteristics. General Hydroponics Purpinator feeds plants the precise building blocks needed to enhance anthocyanin and flavonoid production. While its sister product, General Hydroponics Terpinator Nutrients, focuses on maximizing aromatic intensity, Purpinator unlocks vibrant purple coloration in capable cultivars while simultaneously boosting terpene concentrations for superior aromatics and flavor profiles.

Purpinator works at the cellular level by maintaining neutral plant cell pH and delivering targeted nutrients that support secondary metabolite production. After application, the formula travels to plant cells in direct contact with the epidermal layer, where it's stored with the help of bioosmotic potentiators until needed for metabolic processes. This strategic nutrient delivery system ensures your plants have constant access to the compounds required for enhanced pigment and terpene synthesis throughout the flowering cycle.

Compatible with base systems like General Hydroponics FloraNova Bloom Nutrients and any feeding regimen, Purpinator integrates seamlessly into hydroponic, soil, or soilless growing systems. Whether you're cultivating hemp, vegetables, herbs, fruits, or flowers across rockwool, coco, potting mix, or water culture setups, this specialized supplement helps maximize both visual appeal and aromatic quality in your final harvest.

Features

🟣
Enhanced Purple Expression

Facilitates anthocyanin and flavonoid production to unlock vibrant purple coloration in genetically capable cultivars.

🌿
Improved Terpene Profile

Provides building blocks for secondary metabolites, enhancing terpene and terpenoid concentrations for superior aroma and flavor.

🔬
Cellular pH Balance

Maintains neutral plant cell pH to optimize metabolic processes and nutrient utilization at the cellular level.

💎
Increased Trichome Production

May boost trichome counts and productivity through targeted fertilizer additions that support resin production.

How Purpinator Works

1. Transports: After application, Purpinator travels to plant cells in direct contact with the epidermal layer of the plant, ensuring targeted delivery where it's needed most.

2. Stores: Purpinator is stored in plant cells and pushed into storage with the help of bioosmotic potentiators, creating a reservoir of nutrients ready for use during critical metabolic processes.

3. Builds: The formula serves as a building block for secondary metabolites, providing the raw materials plants need to synthesize complex compounds like anthocyanins and terpenes.

4. Produces: By providing building blocks for secondary metabolites, Purpinator may increase trichome counts and productivity through the strategic addition of targeted fertilizer compounds.

Key Benefits

Improved Color: Purpinator facilitates the production of anthocyanin compounds and other flavonoids, which improve the expression of phenotypic characteristics such as purple coloration in capable cultivars. This dramatically enhances the final bag appeal of finished product and sets your harvest apart from the competition.

Enhanced Aromatics: Purpinator helps enhance your plants' natural terpene profile for an improved concentration of terpenes and terpenoids, which results in superior aroma and flavor in your final product. To further maximize flower weight alongside color, many growers integrate General Hydroponics Liquid KoolBloom Nutrients during the final ripening phase.

Support & Manuals

FAQ

Will Purpinator make all my plants turn purple?+

Purpinator enhances purple coloration only in genetically capable cultivars—plants that already possess the genetic traits for purple expression. It provides the nutritional building blocks needed for anthocyanin production, but the underlying genetics must be present for color changes to occur.

Can I use Purpinator with my existing nutrient line?+

Yes, Purpinator is designed to work alongside General Hydroponics FloraGro Nutrients or any feeding regimen. It's compatible with hydroponic, soil, and soilless growing systems, making it a versatile supplement that integrates seamlessly into your current feeding schedule.

When should I start using Purpinator in my grow cycle?+

Refer to the Purpinator feeding chart for specific application timing and dosage rates. Generally, Purpinator is applied during the flowering cycle when plants are actively producing secondary metabolites and expressing phenotypic characteristics like color and terpene production.

How does Purpinator improve terpene production?+

Purpinator provides the building blocks for secondary metabolites, which include terpenes and terpenoids. By supplying plants with targeted nutrients and maintaining optimal cellular pH, it helps enhance your plants' natural terpene profile, resulting in improved aroma and flavor concentrations.

What are bioosmotic potentiators and how do they work?+

Bioosmotic potentiators are compounds in the Purpinator formula that help push nutrients into plant cell storage. This creates a reservoir of building blocks that plants can access during critical metabolic processes, ensuring consistent availability of nutrients needed for anthocyanin and terpene production.

Will Purpinator increase my final yield?+

Purpinator is primarily designed to enhance color expression and terpene production rather than increase total biomass. However, by potentially increasing trichome counts and productivity through targeted fertilizer additions, it may contribute to improved resin production and overall quality of your harvest.

What growing media is Purpinator compatible with?+

Purpinator works with all growing media including rockwool, potting mix, coco, peat lite mix, in-ground soil, and water culture systems. It's suitable for both indoor and outdoor cultivation of hemp, vegetables, herbs, fruits, flowers, and other high-value crops.

Does Purpinator affect nutrient solution pH?+

Purpinator is designed to maintain neutral plant cell pH at the cellular level, which is different from nutrient solution pH. You should still monitor and adjust your nutrient solution pH as normal using General Hydroponics Liquid pH Up Nutrients and General Hydroponics Liquid pH Down Nutrients to maintain the optimal 5.5-6.5 range.
