Every grower knows: without nutrients, there is no healthy growth. But even the best fertilizers lose their value if your crop cannot absorb them. One of the most decisive factors in this process is the pH of your nutrient solution. While much of the focus is often on lowering pH — since many water sources and feeding recipes tend to be too high — the opposite problem is just as common: a pH that is too low.

A low pH blocks essential nutrients and creates imbalance in your crop. Calcium and magnesium become less available, the root zone turns acidic, and plants experience stress. Even with a perfectly designed feeding schedule, uptake lags behind.

That’s why raising pH is just as important as lowering it. With Profs pH+ you have a powerful and reliable pH increaser in hand that quickly and stably brings your nutrient solution back into the optimal range. In doing so, you open the door to maximum uptake and vigorous growth.

Why a low pH causes problems

pH is the measure of acidity in a solution. On the scale from 0 to 14, 7 is neutral; lower is acidic, higher is alkaline. Most growing systems perform best within a pH range of 5.5 to 6.5. Within this window, nutrients are most soluble and therefore available for uptake.

When pH falls below this range, issues begin to appear. Calcium and magnesium become less available, while metals such as manganese and aluminum become overly soluble. This leads to root stress, slowed growth, and often leaf burn or discoloration. Phosphorus availability can also be compromised in overly acidic conditions, directly impacting energy management and flowering.

In short: a pH that is too low closes the door to certain nutrients while opening it too wide for others in harmful amounts. The result is imbalance that weakens your crop and reduces yield potential.

The pH of your nutrient water is not the same as the pH in your medium — but they do influence each other

Many growers assume that the pH they measure in their tank is automatically the same as the pH in their soil or substrate. This is not true. They are two distinct values that are connected, but each follows its own dynamics.

• The pH of your nutrient water: this is the inlet value — the pH your plants receive with irrigation at that moment. You can control this directly and accurately with Profs pH+.
• The pH of your soil or medium: this is a system value. Substrates such as soil, coco, and rockwool have buffering capacity. Lime, organic matter, and chemical properties in the medium slow down changes. Roots and microorganisms further influence this balance.

The two values are different, but they do influence each other. By consistently providing nutrient water at the correct pH, you also gradually steer the pH of your medium. This process takes time, but stability in your nutrient solution is the key to long-term balance in the root zone.

What makes Profs pH+ unique?

Profs pH+ was developed specifically for professional use. It excels in three areas:

1. Powerful and effective
   Small dosages already produce a noticeable increase in pH. This makes the product efficient to use and gives you precise control.
2. Stable and predictable
   Every addition of Profs pH+ has a consistent effect. No fluctuations, just reliable results you can count on.
3. Market-conform pricing
   Profs pH+ is priced in line with other pH increasers, but because you need less per correction, your cost per liter of nutrient solution is often lower.

On top of that, Profs pH+ is versatile: suitable for hydro, coco, and soil, and compatible with virtually all feeding programs and additives.

How to use Profs pH+ in practice

Raising pH is not guesswork. It requires a structured approach.

1. Prepare your full nutrient solution
   Add all fertilizers and additives first. Let them dissolve fully and mix thoroughly.
2. Measure the pH
   Always use a reliable digital pH meter — not strips.
3. Add Profs pH+ in small steps
   Drip or pour in a small amount, stir well, and wait a few minutes.
4. Measure again
   Check your value and repeat if necessary until you are within your target range (for many systems, 5.8–6.2).
5. Record your dosage
   By noting the amounts per batch, you can correct faster and more consistently in the future.

The key is to work calmly and systematically. A large correction all at once often overshoots the target and causes instability.

Safety when using Profs pH+

Profs pH+ is a strong base. Handle it with care.

• Protect yourself: wear gloves and safety goggles.
• Work ventilated: avoid fumes or splashes.
• Use resistant materials: make sure tanks, pipes, and fittings can withstand bases.
• Storage: keep in a cool, dry place, out of reach of children and pets.

Following these simple steps ensures safe use without worries.

Common mistakes when raising pH

Even experienced growers sometimes run into problems when increasing pH. Here are the most common pitfalls:

• Adding too much at once → overshooting, then having to bring it back down with acid, causing fluctuations.
• Not mixing thoroughly → measuring too quickly leads to incorrect readings and unnecessary additions.
• Using inaccurate tools → strips or poorly calibrated meters give false values.
• Expecting medium pH to change immediately → this is a slow process. Focus on consistent nutrient water.
• Chasing exact decimals → pH management is about ranges, not exact numbers after the decimal point.

What Profs pH+ delivers

By consistently keeping your nutrient water within the optimal range using Profs pH+, you gain:

• Maximum nutrient uptake;
• A stable root environment with less stress;
• Better balance between macro- and micronutrients;
• Uniform growth and stronger plants;
• Higher yields and improved quality.

The greatest advantage: peace of mind and predictability. No more surprises, just a system that works as intended.

Frequently asked questions about Profs pH+

Do I always need to use pH+?
No. Only when your measurement shows the pH of your nutrient water is too low. Correcting without measuring is not recommended.

Can I use Profs pH+ in any system?
Yes. It is suitable for hydro, coco, and soil, and works with all common feeding programs.

How often should I measure?
In recirculating systems daily; in drain-to-waste systems at every new batch of feed.

Is Profs pH+ safe for my crops?
Yes. When used correctly, Profs pH+ is safe and effective. It was developed for professional cultivation.

How about the price?
Profs pH+ is market-conform in price, and thanks to its high effectiveness it is economical in use.

Conclusion

pH is the foundation of nutrient uptake. When your pH is too low, part of your feed remains unavailable, creating stress and lowering yields.

With Profs pH+ you have a powerful, efficient, and reliable tool to raise the pH of your nutrient water quickly and stably. This keeps your crop balanced, maximizes nutrient uptake, and creates peace of mind in your cultivation.

Serious growers know: pH management is not optional, it’s fundamental. With Profs pH+ you raise pH simply and stably — and take your crop to the next level.
