Growth Technology pH Down – Precision pH Control for Optimal Nutrient Uptake
Professional-Grade 85% Phosphoric Acid Formula for Stable pH Adjustment
Maintain perfect nutrient absorption with Growth Technology pH Down, the strongest, most reliable pH adjuster for hydroponics, coco, and soil-less systems. With its high-concentration 85% phosphoric acid formula, a little goes a long way in locking your nutrient solution in the ideal 5.5–6.5 range—where plants absorb nutrients most efficiently.
Why Proper pH Control Matters
🌿 Nutrient Availability – Outside 5.5–6.5 pH, plants can’t absorb key minerals
⚖️ Prevents Lockout – Stops deficiencies before they start
🔬 Stabilizes Solutions – Counters pH drift in recirculating systems
🌱 Healthier Roots – Avoids stress-induced stunting
Key Features & Benefits
✔ Ultra-concentrated – 85% phosphoric acid (more adjustments per bottle)
✔ Fast-acting – Drops pH within seconds of mixing
✔ Nutrient-friendly – Phosphoric acid supports bloom phase
✔ Trusted by labs & growers – Consistent, dependable results
How to Use Safely & Effectively
-
Always add nutrients first, then adjust pH
-
Dilute before use – Add 1mL pH Down to 1L water (then dose slowly)
-
Mix well & retest – Small amounts drastically affect pH
-
Recirculating systems – Check pH daily (drift is common)
Dosage Guide:
-
Starting point: 0.5–1mL per 10L nutrient solution
-
Always titrate slowly!
Critical Safety Precautions
⚠️ Wear gloves & goggles – Concentrated acid burns skin/eyes
⚠️ Add acid to water – NEVER water to acid (risk of violent reaction)
⚠️ Lock away from children/pets
⚠️ Store in cool, dark place
Who Needs pH Down?
-
Hydroponic growers (DWC, NFT, aeroponics)
-
Coco coir users (buffers high pH water)
-
Recirculating systems (combats daily pH rise)
-
Any serious gardener optimizing nutrient uptake
Why Cheap pH Adjusters Fail
"After wasting money on weak, inconsistent pH products, switching to Growth Technology’s 85% formula was a game-changer. 1 bottle lasts 3x longer, and my plants never suffer pH swings." – Jake R., Commercial Hydroponic Farmer
Frequently Asked Questions
Q: How often should I adjust pH?
A: Test daily in hydro, weekly in soil/coco. Recirculating systems often need daily tweaks.
Q: Can I use vinegar instead?
A: Not recommended—vinegar is unstable and promotes microbial growth.
Q: What if I spill it?
A: Flush with water immediately. Neutralize with baking soda if needed.
Q: Does it expire?
A: No, but store tightly sealed to prevent moisture absorption.
