Biobizz Bio-PH- PH Regulator 5L pH DOWN

Adjust pH Downward Naturally With Biobizz Bio-PH-, 5 L

Maintaining correct pH is one of the most critical factors in growing healthy plants. When pH drifts too high, nutrient lockout occurs — plants lose access to iron, manganese, zinc, and other essential micronutrients even when those elements are present in the nutrient solution. In soil, coco, and hydroponic systems, pH must be checked and corrected regularly to keep nutrient uptake efficient throughout the grow cycle.

Biobizz Bio-PH- is a plant-based pH down solution formulated with citric acid rather than harsh synthetic phosphoric or sulfuric acids. Designed for the plant-based farming sector, it lowers pH gently and precisely in all growing media — soil, coco substrate, and hydroponic systems — without disrupting nutrient availability or introducing synthetic chemical residue.

Key Features & Benefits

• Citric acid formula — uses citric acid — a naturally derived organic acid — rather than the synthetic phosphoric or sulfuric acids found in conventional pH down products.
• Precise pH control — enables gradual, controlled pH adjustment to avoid overcorrection and pH swings that can stress plants or destabilize nutrient solutions.
• Compatible with all Biobizz nutrients — integrates directly into the Biobizz feeding program without reacting adversely with organic nutrient components.
• Works in soil, coco, and hydroponic systems — suitable for use in all standard growing media — soil, coco substrate, hydroponic reservoirs, and soilless mixes.
• 5 L volume — available in five liters for mid-scale growing operations.

Who Should Use Biobizz Bio-PH- (5 L)

Growers using Biobizz organic nutrients who need to lower the pH of their nutrient solution before watering — particularly those running coco or hydroponic systems where pH must be precisely managed, or soil growers whose tap water or nutrient mix runs alkaline.

How to Use Bio-PH- in Your Nutrient Mix

Always prepare your full nutrient solution before adjusting pH. Add the required nutrient doses to water, mix well, then check pH with a calibrated meter. Add Bio-PH- drop by drop while stirring until the target pH is reached. Target ranges vary by growing medium: soil typically 6.0–7.0, coco and hydroponic systems typically 5.5–6.5. Allow the solution to stabilize before final pH measurement. Follow the Biobizz official Nutrient Schedule for recommended dosages.

Frequently Asked Questions

What is Biobizz Bio-PH-?

Bio-PH- is a plant-based pH down solution made with citric acid. It is designed for growers using organic and natural growing approaches who need to lower the pH of their nutrient solution before watering. It is part of the Biobizz pH adjustment range.

What pH does Bio-PH- work in?

Bio-PH- can be used to lower pH in soil (target range 6.0–7.0), coco substrate (5.5–6.5), and hydroponic systems (5.5–6.5). Always measure pH after adjusting and allow the solution to stabilize before final verification.

Does Bio-PH- affect nutrients in solution?

Bio-PH- is formulated to lower pH without disrupting the availability of nutrients in solution. Unlike phosphoric acid-based pH down products, it does not add excess phosphate to the nutrient mix, which can skew nutrient ratios over time.

Can I use Bio-PH- with all Biobizz fertilizers?

Yes — Bio-PH- is designed to be compatible with all Biobizz organic nutrients and supplements. Add it after mixing your complete nutrient solution, and adjust gradually with a calibrated pH meter.

How should I store Bio-PH-?

Store Bio-PH- in a cool, dry location away from direct sunlight. Keep the container tightly sealed between uses. pH adjustment solutions should be handled with care — avoid contact with eyes and skin.
