Fix Root Rot, Slime, Blockages & Nutrient Problems—Before They Destroy Your Yield

If your system is suffering from brown or slimy roots, root rot (Pythium), algae or biofilm buildup, clogged irrigation lines, or poor nutrient uptake—The cause of this problem could be a few things. But essentially its your system hygiene.

Guardian Hydro Clean is a professional-grade hydroponic steriliser and nutrient conditioner designed to eliminate pathogens, clean your system, and restore a healthy root zone for maximum plant performance.

The go-to solution for growers searching for a root rot treatment in hydroponics, a hydroponic system cleaner, or a reliable way to remove slime, algae, and biofilm from their grow setup in Australia.

Why Guardian Hydro Clean Works

Eliminates Root Rot & Harmful Pathogens — Targets fungi, bacteria, and parasites including Pythium—the leading cause of root rot in hydroponic systems.
Cleans Slime, Algae & Biofilm — Breaks down organic buildup that blocks irrigation lines, reduces oxygen flow, and causes system failure.
Improves Nutrient Efficiency — Conditions your nutrient solution so plants absorb minerals more effectively and develop stronger, healthier roots.
Prevents Root Browning — Keeps roots white, oxygen-rich, and highly absorbent throughout the grow cycle.
Protects Your Entire System — Stops blockages in pipes and drippers, sludge buildup, and the organic waste that attracts pests.

Common Grow Problems This Solves

Guardian Hydro Clean is specifically designed to address the most damaging system hygiene issues in hydroponics:

Root rot caused by Pythium and bacterial infection
Brown, slimy, or dying root systems
Algae and biofilm accumulation in reservoirs and lines
Clogged drippers and irrigation systems
Fungus gnats and root-zone pests attracted by organic waste

By sterilising the nutrient solution and removing pathogen food sources, Hydro Clean restores a clean root environment that supports efficient feeding and vigorous growth.

Why System Cleanliness Directly Impacts Yield

Most growers focus on their nutrient program—but a contaminated system causes nutrient lockout, oxygen deprivation, and disease outbreaks that no feeding schedule can overcome.

Dirty system = nutrient lockout, root stress, disease spread, yield loss
Clean system with Hydro Clean = better root health, more efficient feeding, stronger plants, higher yields

System hygiene is your insurance policy against root rot and system failure—not an optional extra.

Performance Benefits

Cleaner, healthier root systems with visible improvement
Faster plant recovery from disease and heat stress
Improved nutrient uptake and feeding efficiency

Stronger, more vigorous plant growth throughout the cycle

How to Use Guardian Hydro Clean

Maintenance Dose: 2ml per 10L of nutrient solution from week 3 through to harvest

Disease Treatment: Apply directly to the reservoir or affected media to halt the spread of active pathogens

⚠️ Important: Do NOT use in conjunction with hydrogen peroxide (H₂O₂) or beneficial bacteria/microbes—these are incompatible with Hydro Clean.
