HESI pH+ Plus

Hesi pH+ pH adjustment during growth and flowering phase

Hesi Fertilizer pH+ is used to regulate and increase the pH value in nutrient solutions for plant cultivation on soil, coco substrate, and in hydroponic systems. An optimal pH value allows roots to efficiently absorb nutrients. Ideally, the pH value is around 6, with a range of 5.8 to 6.2 considered optimal. A pH value that is too low can cause root damage, while a pH value that is too high can impair nutrient absorption.

Special Suitability and Applications

Hesi pH+ can be used in all growing media and is particularly suitable for coco substrates and hydroponic systems, as precise pH control is required here.

Hesi offers two products for pH adjustment:

• Hesi pH-  – Lowers the pH value.
• Hesi pH+ – Increases the pH value.

Application

Hesi pH+ is used as needed during the growth and flowering phase to correct the pH value in the nutrient solution. The ideal pH range is 5.8 to 6.2. First, the nutrient solution is mixed and the pH value is measured. If it is too low, Hesi pH+ is added drop by drop, the solution is stirred well, and the pH value is measured again. This process is repeated until the desired pH value is reached.

Caution: The product is highly corrosive!
