Botanixx pH Up 25%: Restore Balance for Optimal Growth

Drifting too far into the acidic zone can be just as dangerous as climbing too high. Botanixx pH Up 25% is the corrective tool you need when your nutrient solution becomes too acidic, ensuring your plants stay in the safety zone where growth happens.

Formulated with a concentrated 25% Potassium Hydroxide solution, this additive allows you to gently and accurately raise the pH levels of your reservoir. It is the perfect counterweight to accidental overdoses of acid or natural pH drops during the flowering cycle.

Please note that we currently do not have 1L and 5L bottles in stock at our nursery. Please allow 7–10 days for processing.

Why You Need It

• Correct Acidity Instantly: When pH drops below 5.5, essential macronutrients like Calcium and Magnesium become "locked out," leading to deficiencies and stunted growth. This solution pulls the pH back up to a usable range.

• The "Sweet Spot" Swing: Just like our pH Down, this product helps you maintain that critical window between 5.8 and 6.2. Keeping your reservoir in this range ensures that the full spectrum of nutrients remains available to your roots.

• Bonus Potassium: Because this formula is based on Potassium Hydroxide (KOH), it provides a small additional boost of Potassium—a vital element for water regulation and flower development.

• Concentrated Efficiency: With a 25% concentration, this is a powerful adjuster. You do not need to pour half the bottle in to see a result; a small dose goes a long way.

Safety First

This is a strong alkaline solution (a base) and is corrosive. Always handle with care. We strongly recommend using gloves, goggles, and proper protective gear whenever you are handling or measuring this liquid. Avoid contact with skin and eyes.

Pro-Tip: Check Your Silicon First

If you are using Botanixx Liquid Silicon, remember that silicon is naturally very alkaline and will raise your pH significantly on its own! Always mix your silicon first, let it settle, and check your meter. You might find you do not need to add extra pH Up at all.
