Description

Profs – pH- contains 59% pure phosphoric acid and is formulated for intensive cultivation and horticultural systems. Phosphoric acid is highly effective at lowering pH and also contributes phosphate to the plant.

A stable pH ensures balanced uptake of nutrients. Elements such as iron, manganese, phosphorus, and zinc are poorly absorbed when pH is off, even if present. pH- ensures they remain available and soluble for root uptake.

In addition to lowering pH, phosphoric acid supplies phosphorus — critical for plant energy, cell structure, root formation, and bloom initiation. This dual action is especially useful during stages of high phosphate demand.

The formula is chemically stable and long-lasting. Its 59% concentration is strong enough for all nutrient systems, while remaining compatible with fertilizers. It doesn’t react with other elements and causes no precipitation or water disturbance.

pH- is a core component of Profs’ water management strategy. Within the Basic Liquid line, it helps growers control fundamental parameters like pH and EC without compromising quality or consistency.

Fully soluble and unaffected by temperature changes, the formula integrates seamlessly with the full Profs schedule. Its controlled acidification maintains biological balance in both soil and hydroponics.

By using phosphoric acid instead of aggressive alternatives like nitric or sulfuric acid, pH- avoids disturbing nitrogen or sulfur levels — keeping the feeding scheme predictable and balanced.

pH- is suitable for any growth stage, supporting both root development and nutrient uptake efficiency throughout the crop cycle. It enables the full Profs nutrient line to perform optimally within the target pH range.
