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.

    Frequently Asked Questions

    What is your returns policy?

    We always aim to make sure our customers love our products, but if you do need to return an order within 14 days of purchase (not including plants*), or any items are damaged, we’re happy to help. Just email us directly at hello@growtropicals.com, and we’ll take you through the process. 

    Please note: we cannot be held liable for any packaging costs should the original packaging be discarded.

    *Unfortunately we cannot accept returns of undamaged plants as these are perishable items and are not saleable upon return. If a plant is damaged, we will compensate for this as per our live arrival guarantee.

    When will my order arrive and how much is shipping?

    When placing your order, you can choose from three dispatch speeds to suit your needs: Economy (prepared and shipped within 4-5 days), Standard (3-5 days), or Express (dispatched the very next day). Please keep in mind that "dispatch" refers to the time it takes our team to prepare and pack your items before handing them over to the courier, not the total delivery time.

    Shipping costs are based on your total order value and will be calculated at checkout, with free shipping automatically applied to all orders over £60. For a full breakdown of shipping prices see our Help Centre.

    Additionally, to protect the health and quality of our live plants, orders containing plants are exclusively shipped Monday through Thursday. This careful scheduling prevents your plants from being stuck in a dark shipping depot over the weekend, ensuring they arrive at your door vibrant and healthy.
