Hydroponics pH Down — the professional-grade solution for lowering and stabilising nutrient solution pH in all hydroponic systems across the UAE. Formulated with food-grade phosphoric acid for safe, effective, and precise pH reduction.

Why pH Control is Critical in UAE Hydroponics

In the UAE’s climate, nutrient solutions often drift alkaline due to tap water quality. Our pH Down solution corrects this quickly, keeping your pH in the optimal 5.5–6.5 range where all major plant nutrients are fully available.

Features & Benefits

• Food-Grade Phosphoric Acid — safe for edible crops including lettuce, herbs, tomatoes
• Concentrated Formula — a small dose lowers pH across large reservoirs
• Compatible with All Systems — NFT, DWC, Dutch Bucket, drip irrigation, aeroponics
• UAE Stock — fast delivery to Dubai, Abu Dhabi, Sharjah, RAK, and all emirates
• Trusted by UAE Growers — rated 4.2★ by 25+ verified UAE customers

How to Use pH Down

Add pH Down in small amounts (3–5ml per 10L) to your nutrient reservoir while stirring. Re-test pH after 15 minutes using a calibrated pH meter. Target pH of 5.8–6.2 for most crops. Never add directly to concentrated nutrients — dilute first.

Compatible Growing Systems

• NFT (Nutrient Film Technique) systems
• DWC (Deep Water Culture) reservoirs
• Dutch Bucket and drip systems
• Coco coir and rockwool substrate growing
• Aquaponics systems

Frequently Asked Questions

What pH should I target for hydroponics? Most crops thrive between 5.8 and 6.2. Leafy greens prefer 6.0–6.5; fruiting plants like tomatoes and peppers do best at 5.8–6.0.

How often should I check pH? Daily checks are recommended in hot UAE weather as evaporation can cause pH drift. Automated pH dosing systems are ideal for larger operations.
