BAC pH Up Potassium Hydroxide pH Increaser (1 L) is the definitive solution for correcting and stabilizing the acidity of your irrigation water or nutrient solution, a fundamental step to unlock the full genetic potential of your plants and avoid the silent killer of many crops: an incorrect pH.

Have you ever invested weeks in your plants only to see them turn yellow, grow slowly, or show nutrient deficiencies despite using top-shelf fertilizers? That frustration, that waste of time and resources, often comes down to one invisible enemy: a pH that’s out of the ideal range. When the pH is off, your plants literally can’t eat, no matter how rich your nutrient mix is. You’re pouring money down the drain and watching your hard work stagnate.

This imbalance doesn’t just stunt growth; it weakens your plants, making them vulnerable to pests and diseases, turning a promising harvest into a constant battle. The cost isn’t just in lost nutrients, but in lost time, yield, and the satisfaction of a successful grow. It’s the gap between a mediocre result and the explosive, resinous harvest you know your genetics can deliver.

This is where BAC pH Up becomes your essential ally. This professional-grade potassium hydroxide formula is the precise, reliable tool you need to take absolute control of your cultivation environment. It’s not just a correction; it’s the key to unlocking efficient nutrient uptake, robust health, and ultimately, the massive, potent buds you’re aiming for.

Quick spec sheet of the product

  • Brand: BAC (B.A.C. – B’cuzz)
  • Product Type: pH regulator / pH increaser.
  • Format: 1-litre bottle with practical dosing cap.
  • Active Ingredient: Potassium Hydroxide (KOH).
  • Primary Function: Raises and stabilizes the pH level of irrigation water or nutrient solutions.
  • Compatibility: Suitable for all cultivation media: soil, coco coir, and hydroponic systems.
  • Application Stage: Used throughout the entire growth cycle (Vegetative and Flowering stages) whenever pH correction is needed.
  • Key Benefit: Enables precise pH control, which is crucial for optimal nutrient absorption.

Key advantages over basic pH correction methods

While you could try improvised methods, BAC pH Up offers a professional, controlled, and safe approach. Using random household products is a gamble; this product is precision engineering for plants.

  • Precision & Stability: Potassium Hydroxide provides a strong, predictable, and stable pH increase, unlike bicarbonate-based products that can fluctuate.
  • Nutrient-Friendly: Formulated specifically for plant nutrition, it doesn’t introduce unwanted salts or elements that could lock out other nutrients.
  • Fast-Acting: Works immediately upon mixing, allowing for quick corrections and getting your plants back on track without delay.
  • Professional-Grade Purity: Manufactured under strict controls for horticulture, ensuring consistency and reliability batch after batch.
  • Plant Health Focus: Correct pH reduces plant stress, strengthens cell walls, and improves resistance to pests and pathogens.
  • Yield Maximizer: By ensuring optimal nutrient availability, it directly contributes to maximizing final yield and quality.

Real benefits you’re going to notice

This isn’t about abstract chemistry; it’s about tangible results in your grow room or garden. When you integrate BAC pH Up into your routine, you stop guessing and start seeing a direct impact.

First, you’ll see your plants become more vibrant. The persistent yellowing or deficiency signs disappear because the roots can now efficiently absorb the nitrogen, phosphorus, potassium, and micronutrients you’re providing. Growth becomes uniform and vigorous.

Secondly, you gain peace of mind and save resources. No more wasting fertilizers that your plants can’t use. You apply nutrients knowing they will be absorbed, making every millilitre count. It turns cultivation from a constant troubleshooting session into a smooth, predictable process.

Finally, the ultimate benefit: heavier, denser, and more aromatic buds. A plant that feeds optimally throughout its cycle dedicates all its energy to producing top-quality flowers, not fighting to survive. The difference in resin production, terpene profile, and final weight is palpable.

Step-by-step usage guide

  1. Prepare Your Solution: Fill your reservoir or watering can with the final volume of water you will use.
  2. Add Nutrients First: Always add your base fertilizers and additives before adjusting the pH. Adding nutrients usually alters the pH.
  3. Measure Initial pH: Use a calibrated pH meter to check the pH of your nutrient solution. The ideal range is typically between 5.8 and 6.3 for hydroponics/coco, and 6.0 to 6.8 for soil.
  4. Add BAC pH Up Gradually: Shake the bottle well. Add a few drops (using the dosing cap) to the solution, stir thoroughly, and wait a minute.
  5. Re-measure and Repeat: Measure the pH again. Repeat steps 4 and 5 until you reach your desired target pH. Always add small amounts to avoid overshooting.
  6. Apply to Plants: Once the pH is stable and correct, use the solution to water your plants as normal.
  7. Clean Your Meter: Always rinse your pH meter probe with clean water after use and store it properly with storage solution to ensure its longevity and accuracy.

Frequently Asked Questions

What is the ideal pH range for cannabis?

For hydroponic and coco coir systems, aim for a pH between 5.8 and 6.3. For soil cultivation, a slightly higher range of 6.0 to 6.8 is ideal. BAC pH Up helps you reach and maintain this sweet spot.

Why use a specialized product like BAC pH Up instead of baking soda?

Baking soda (sodium bicarbonate) can add unwanted sodium to your medium, potentially causing salt buildup and nutrient lockout over time. BAC pH Up uses potassium hydroxide, which is a plant-available form of potassium, making it a much safer and more effective choice for consistent, professional results.

How often should I check and adjust my pH?

You should check the pH of your nutrient solution every time you water or feed. Environmental factors and nutrient uptake can cause pH to drift. Regular monitoring and correction with BAC pH Up (or pH Down) are non-negotiable for optimal growth.

Can I use BAC pH Up in organic grows?

Yes, absolutely. While it is a mineral-based product, it is perfectly compatible with organic cultivation mediums and nutrient lines. Its function is purely to correct pH, allowing your organic nutrients to be absorbed effectively.

What happens if my pH is too low (too acidic)?

A low pH (below 5.5 in hydro/coco or below 6.0 in soil) locks out crucial nutrients like calcium, magnesium, and phosphorus. This leads to severe deficiencies, stunted growth, and weak plants. BAC pH Up corrects this immediately.

Is this product compatible with all BAC and other brand nutrients?

Yes, BAC pH Up is formulated to be universally compatible. It works seamlessly with the entire BAC nutrient line and with fertilizers from any other major brand like Advanced Hydroponics or Advanced Nutrients, making it a versatile tool in your grow room.

Personal Experience of Pevgrow’s CEO (Alan)

“Let’s be real: pH management used to be my biggest headache. I’d see my plants struggling, and it was always a guessing game. Since we started using and recommending BAC pH Up, that stress is gone. The precision is unmatched. I use it in my coco-perlite mixes. After adding my base feed, I check the pH. If it’s dropped too low (which it often does), a few drops of this, a good stir, and bam – back to a perfect 6.0. The plants respond within days. The growth is uniform, the leaves stay a deep, healthy green, and I know every euro I spend on other top-shelf nutrients is actually being used by the plant. It’s not a ‘nice-to-have’; it’s as essential as the lights themselves. For any grower, from beginner to pro, having reliable pH Up and pH Down on hand isn’t optional – it’s the foundation of a successful harvest. This 1L bottle lasts for ages because you use so little each time, making it one of the most cost-effective investments you can make for your garden.”
