Boost your hydroponic or soil growth with Intense Nutrients pH Down Ultra. This NPK-neutral formula offers rapid, stable pH adjustment, preventing nutrient lockout and system mineral deposit build-up. Achieve the optimal pH range (5.5-6.5) for maximum nutrient uptake and robust plant health.
-
Achieving the perfect nutrient balance is crucial for maximising plant health and yield in any hydroponic system. Intense Nutrients pH Down Ultra is the essential, professional-grade solution engineered to provide rapid, precise, and long-lasting pH stabilisation in your nutrient reservoir. Using an advanced NPK-neutral formulation based on Methanesulfonic Acid, this product sets a new standard for growers who demand accuracy without compromising their carefully balanced feed ratios. Say goodbye to nutrient spikes and inconsistent readings; ensure your plants can absorb every element efficiently, from root to tip.
Key Benefits of using pH Down Ultra
- NPK-Neutral Formulation: Unlike traditional phosphoric acid pH adjusters, this ultra-pure formula will not spike your Nitrogen (N), Phosphorus (P), or Potassium (K) levels, preserving the integrity of your feeding schedule.
- Rapid & Stable Adjustment: Quickly brings your nutrient solution into the ideal, slightly acidic range (typically pH 5.5–6.5) and holds it there for longer than common alternatives like citric acid.
- Maximise Nutrient Uptake: Maintaining the correct pH is vital for root health and allows your plants to fully uptake essential macro and micro-nutrients required for robust vegetative growth and heavy flowering.
- Protects System Components: Aids in the prevention of mineral deposit build-up and scale in reservoirs, irrigation pipework, and pumps, promoting system longevity and consistent delivery.
What Intense Nutrients pH Down Ultra is Used For
Intense Nutrients pH Down Ultra is used to accurately lower the pH level of your hydroponic or recirculating nutrient solution. It is vital for ensuring that all the elements in your base nutrients remain soluble and bio-available to the plant roots. The secondary use is as a descaler, keeping your entire system clean and free from mineral blockages.
How to Use pH Down Ultra
Always use appropriate safety equipment, such as gloves and goggles, when handling this concentrated acid solution.
For pH Adjustment:
- After mixing your base nutrients and any additives into your reservoir, measure the current pH using a reliable pH meter or test kit. These can be found in the pH Management section.
- Add a small amount of pH Down Ultra directly to the reservoir.
- Mix the nutrient solution thoroughly for 1–2 minutes.
- Re-test the pH level.
- Repeat steps 2–4 until the desired pH (typically between 5.8 and 6.2 for most hydroponic crops) is achieved. Note: Due to the high concentration, precise dosage is dependent on your water hardness and buffer capacity; always add slowly and incrementally.
For Scale Prevention (Maintenance):
- Initial Dose: Add approximately 1ml per litre of nutrient solution when setting up a fresh reservoir.
- Maintenance Dose: Use 0.5ml per litre every time you top up your reservoir, or as needed, to prevent mineral deposit build-up in pipework and pumps.
Available in 250ml.
Frequently Asked Questions
How often should I check and adjust the pH in my hydroponic system?
It is highly recommended to check your nutrient solution's pH level daily, especially during peak growth and bloom phases. Higher reservoir temperatures can accelerate pH drift, requiring more frequent monitoring and adjustment.Is it better to adjust the pH before or after adding nutrients and supplements?
Always add all your base nutrients and supplements first, mix the solution thoroughly, and then measure and adjust the pH. The chemicals and buffers within the nutrient products themselves will alter the starting pH of the water, making any prior adjustment inaccurate.Why does my pH keep rising even after I use pH Down Ultra?
A persistently rising pH is a common phenomenon often caused by the natural biological processes of the plants releasing alkaline ions into the solution as they uptake nutrients. High alkalinity in your source water (hard water) or high reservoir temperatures can also contribute.What is the ideal pH range I should aim for when using pH Down Ultra?
While the ideal range varies slightly by crop, most plants thrive in a slightly acidic range between pH 5.5 and 6.5. For most hydroponic growers, targeting a sweet spot between pH 5.8 and 6.2 ensures optimal nutrient uptake for all essential elements.SKU: 1840 Free delivery on orders over £60*
