Pythoff Plus – Organic-Compliant Pythium & Root Rot Prevention | 1L & 5L

Stop Root Rot Before It Stops Your Grow

Pythoff Plus is a professional-grade water treatment designed to protect your root zone from pythium, root rot, and biofilm buildup — without compromising your crop or your organic compliance status.

Why Growers Choose Pythoff Plus

🌿 Non-toxic & non-systemic — safe to use from seed all the way through to harvest

✅ Organic-farming compliant — no systemic chemicals, meets guidelines that prohibit systemic inputs

🚿 Prevents plumbing blockages — keeps drippers, jets, filters, and pumps flowing freely

💧 Extends nutrient solution life — maximises the effective working life of your water and nutrient mix

🔧 Compatible with all systems & substrates — works in DWC, NFT, coco, rockwool, and more

How to Use

Add Pythoff Plus directly to your reservoir or irrigation system as a preventative treatment throughout the growing cycle. Dose consistently for best results — prevention is far more effective than cure when it comes to pythium.

⚠️ Important: Pythoff Plus is not compatible with hydrogen peroxide (H₂O₂) or beneficial bacteria products. Do not use alongside these inputs.

Available Sizes

• 1L — ideal for home growers and smaller systems
• 5L — best value for commercial grows and larger reservoirs

If you're running a recirculating system, pythium is one of the biggest threats to your yield. Pythoff Plus gives you a safe, proven, and compliance-friendly way to keep your root zone clean and your plants thriving — from day one to harvest day.
