Description

Keep your irrigation system, substrates and root zones pristine with Athena Cleanse. A powerful yet plant-safe cleaning and flushing solution that helps prevent mineral build-up, biofilm and scale. Ideal for hydroponics, coco, soil or recirculating systems, Athena Cleanse is designed to maintain optimal growing conditions and support healthy, vigorous root development throughout every stage of growth.

Athena Cleanse uses a mild oxidiser based on hypochlorous acid, derived via a proprietary electro-chemical process, making it non-toxic, non-nutritive and safe for plants at any stage, from seedlings and clones to mature flowering crops.
The solution breaks down accumulated mineral salts, organic residues and biofilm in media, reservoirs, pipes and irrigation lines, converting them into harmless by-products. This ensures cleaner water flow, fewer blockages, improved oxygen and nutrient availability around roots and a reduced risk of root-zone problems.

Key Features & Benefits

  • Non-toxic & Safe for All Growth Stages: Plant-safe and non-nutritive, suitable for seedlings, clones and mature plants without interfering with nutrient routines
  • Neutral pH & Low TDS: Maintains stable pH and mineral balance, preventing EC spikes or nutrient disruption
  • Prevents Mineral Scale & Biofilm: Ideal for recirculating systems, reservoirs and drip lines, dissolving scale, precipitates and biofilm that can block lines or impair nutrient delivery
  • Improves Root Zone Oxygen & Nutrient Access: Clears build-up and organic residue, promoting healthier roots and better nutrient uptake
  • Extends System Lifespan & Reduces Maintenance: Regular use keeps irrigation components running smoothly and reduces the need for frequent deep cleaning
  • Routine Preventative Maintenance Treatment: Can be used as a flush for media and lines, or as a surface sanitizer/foliar spray when diluted appropriately

How to Use

Regular Maintenance: Mix 2 to 5 ml per gallon (~0.5 to 1.3 ml per litre) of water for routine irrigation upkeep
Deep Clean / Severe Conditions / System Flush: Increase dose to 5 to 10 ml per gallon (~1.3 to 2.6 ml per litre) to flush media or recirculating systems
Clones / Cuttings Treatment: Use diluted to sanitise water or media, promoting healthy root formation
Foliar or Surface Cleaning: When correctly diluted, can sanitize surfaces, equipment, pots or work areas
Important: Athena Cleanse is not a nutrient and should never be mixed directly with nutrient solutions during feeding cycles. Flush thoroughly before reintroducing nutrients

Frequently Asked Questions (FAQ)

Is Athena Cleanse safe to use on plants at any stage of growth?
Yes. It’s non-nutritive and plant-safe, suitable for seedlings, clones and mature plants.

Will Cleanse affect my nutrient solution or cause pH/EC issues?
No. Neutral pH and low TDS ensure mineral balance is maintained and nutrient solutions remain stable when used as directed.

Can I use Athena Cleanse with hydro, coco, soil or recirculating systems?
Yes. Highly versatile and suitable for hydroponics, coco, rockwool, soil, RDWC/DWC systems, drip irrigation and more.

How often should I use Cleanse?
Many growers use it regularly, such as every reservoir change or growth cycle, as preventative maintenance. Use maintenance dose routinely and increase to flush-strength if build-up occurs.

Can Cleanse help with root disease or algae/biofilm issues?
Yes. By breaking down biofilm, organic residue and mineral deposits, it maintains a cleaner, oxygen-rich root environment, reducing the risk of anaerobic microbial growth, root rot and system blockages.

Athena Cleanse is essential for growers in hydroponics, coco, or recirculating systems, or anyone wanting to keep irrigation setups clean and efficient. It prevents mineral scale and biofilm, promotes better oxygen and nutrient availability to roots, and extends the lifespan of your system.
