Description
Description
Athena Nutrients Renew is a liquid irrigation line cleaner for the removal and prevention of inanimate scale and buildup in irrigation lines between crop cycles. Designed as a premium water line cleaner, it targets the mineral scale, debris, and residue that can reduce flow and create uneven delivery in modern irrigation systems.

Renew is built around a specialized blend of acids, oxidizers, and chelators, giving it multiple modes of action for breaking up stubborn deposits. It is intended to remove mineral buildup and help keep irrigation systems running optimally by addressing the inanimate scale that accumulates on internal surfaces over time. When buildup is left unchecked, emitters and drippers are more likely to perform inconsistently; Renew is made to support clearer lines and more reliable system function from run to run.

The chemistry is purpose-driven and clearly defined. Renew contains etidronic acid (HEDP), a chelator that binds metals and minerals that accumulate in irrigation lines. It also relies on high levels of food-grade hydrogen peroxide, which oxidizes and helps remove scale and other inanimate organic particulates. Together, these inputs are designed to lift deposits that cling to pipes and components, helping reduce the residue that can contribute to restricted flow and recurring maintenance headaches.

Athena Nutrients Renew is designed for irrigation pipes and drip irrigation lines, with coverage that extends beyond tubing alone. The intended cleaning scope includes key system parts such as pumps, filters, emitters, manifolds, valves, and membranes, making it a practical choice for growers who want one focused irrigation system maintenance tool for scale and buildup control. The formula is a clear liquid, keeping the product straightforward and easy to identify in a dedicated maintenance routine.

This is a good fit for growers and facilities that prioritize consistent irrigation performance and want a dedicated irrigation line cleaner for between-cycle cleaning. If your goal is removal and prevention of inanimate scale, fewer flow restrictions, and cleaner irrigation components across the system, Athena Nutrients Renew is built to keep lines running clear and maintenance more predictable.

How To Use

How to Use Athena Nutrients Renew - 18.9 Litres

Step-by-step mixing and feeding instructions for Athena Nutrients Renew - 18.9 Litres.

Mixing & preparation

Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Athena Nutrients Renew - 18.9 Litres well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.

Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

Week-by-week feeding schedule

Vegetative stage — Renew

  • Week 1: mix 7.81 ml per litre of water or nutrient solution.

Flowering stage — Renew

  • Week 1: mix 7.81 ml per litre of water or nutrient solution.
Tips for best results
  • Maintain pH and EC/ppm within the range recommended for your growing medium and crop.
  • Use fresh nutrient solution whenever possible and avoid leaving mixed solution stagnant for long periods.
  • Store nutrients in a cool, dark place away from direct sunlight and extreme temperatures.
  • Keep bottles tightly sealed when not in use to reduce air exposure and preserve product quality.
  • Use clean measuring tools and regularly rinse or clean your reservoir, lines, and irrigation equipment.
Common mistakes to avoid
  • Do not mix different nutrients or additives together in concentrated form before adding them to water.
  • Do not exceed the recommended dosage unless you are following a tested, crop-specific feeding plan.
  • Do not skip pH or EC/ppm checks when growing in hydroponic or soilless systems.
  • Do not allow the nutrient solution to freeze or overheat, as this can damage the formulation.
  • Do not ignore the directions on the product label for your specific crop, growth stage, and system type.

Warnings & Safety
Chemical Safety Precautions

Keep out of reach of children and pets. Do not breathe fumes, mist, vapour, or spray. Avoid contact with skin, eyes, and clothing. Wear protective gloves, protective clothing, and eye or face protection when handling this product.

Chemical First Aid – Skin Contact

IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with water or shower. Wash contaminated clothing before reuse. Seek medical advice if irritation, burning, or discomfort persists.

Chemical First Aid – Eye Contact

IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Contact a poison centre or doctor immediately.

Chemical First Aid – Ingestion

IF SWALLOWED: Rinse mouth. Do not induce vomiting unless instructed by a medical professional. Contact a poison centre or doctor immediately.

Chemical First Aid – Inhalation

IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness, or other symptoms occur, seek medical assistance.

Chemical Important – Medical

If medical advice is needed, keep the product label or container available. Always follow the specific instructions and safety recommendations provided by the manufacturer. This safety notice is intended as general guidance and does not replace official label directions or documentation.

Liquid Chemical Handling

Handle liquid chemical products carefully and use only as directed on the product label. Avoid splashing, avoid contact with skin and eyes, and use in a well-ventilated area. Keep the container tightly closed when not in use and wash hands after handling.

Dilution & Mixing Safety

Dilute or mix only as directed on the product label. Use clean measuring tools and avoid splashing. Do not mix with other chemicals, cleaners, pesticides, fertilizers, or additives unless the manufacturer specifically says it is safe to do so.

Oxidizer Safety

Hydrogen peroxide may act as an oxidizer and can react with combustible or incompatible materials. Keep away from heat, sparks, open flame, organic materials, dirt, metals, and other chemicals unless the product label specifically allows contact.

Hydrogen Peroxide Storage

Store tightly closed in the original container, in a cool, dry, well-ventilated area away from direct sunlight, heat, and incompatible materials. Keep out of reach of children and pets. Follow the product label for storage temperature, shelf life, and disposal.

Frequently Asked Questions
Why is 1-Hydroxyethylidene-1 important in nutrient mixes for plants?

It’s important because it helps stop hard-water minerals from forming scale and precipitates that clog irrigation and reduce nutrient availability, which keeps feeding more consistent; it’s unique because it focuses on solution stability and deposit control rather than directly feeding the plant like standard nutrients.

Why is HEDP (1-Diphosphonic Acid) important in plant feeding systems?

HEDP helps keep minerals from forming scale or dropping out of nutrient solutions, which improves nutrient availability and keeps irrigation delivery consistent; it’s unique because it acts as both a mineral-control agent and a scale-growth blocker, not just a simple acid or a single-purpose micronutrient chelator.

Read the full guide

Why is peroxyacetic acid important for plant growth systems?

It helps keep reservoirs, lines, and grow surfaces free of biofilm and harmful microbial buildup, which protects root function and makes nutrient uptake more consistent—making it unique from many other cleaners because it works fast as an oxidizing sanitizer and targets slimy buildup that often hides recurring problems.
