Description

pH+ from Profs is a powerful liquid pH booster based on pure potassium hydroxide. This alkaline compound is specially selected to raise the acidity of nutrient water in a controlled and effective way, without side effects or chemical instability.
pH largely determines nutrient availability. If pH drops below 5.5, calcium, magnesium, and nitrogen compounds become less available, leading to growth stagnation or burn. pH+ brings the level back into range and restores full nutrient uptake.
Potassium hydroxide is fully water-soluble and does not leave residues or cause unwanted reactions. Unlike carbonate-based alternatives, it acts directly, with minimal dose and maximum control.
Besides correcting pH, pH+ delivers extra potassium – essential for sap flow, photosynthesis, sugar transport, and cell wall strength. This makes pH+ both corrective and nutritive, ideal for intensive schedules.
Within the Basic Liquid line, pH+ complements pH-, giving growers complete bidirectional control of water quality.
The formula is stable, easy to dose, and compatible with all other Profs elements – with no precipitation or buffering issues when used correctly.
Thanks to its clean composition and controlled effect, pH+ can be used throughout all crop stages: from rooting to late flowering.
Stable pH = less stress, better distribution, and higher photosynthesis efficiency — for stronger plants and consistent yields.
The use of potassium hydroxide rather than sodium means pH+ also nourishes, not just corrects. Potassium improves fruit sugar pressure, cell firmness, and stomatal regulation — in line with Profs’ philosophy: stimulate and strengthen.
