Ferro PH + 1L Grow

pH Plus is used to increase the pH level of nutrient solution.

The pH level will need to be raised when a more alkaline solution is required. Hesi pH Up contains potassium hydroxide (KOH) 50%. This is a very caustic liquid and should be handled with extreme care. Use Hesi pH up in conjunction with a reliable pH meter to raise the pH level of nutrient solution. Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level. Hesi Ph Up is available in 1 litre bottles.

To use: after adding all nutrients and additives to your nutrient solution, measure the pH level in the tank using a pH meter. If the initial pH reading is lower than that required by your specific crop, add Hesi pH Up. Start by adding very small quantities – drop by drop if necessary – and then mix the solution thoroughly before taking further readings. A pipette is useful for this purpose. Continue to gradually add more Hesi pH Up until the optimal acidity is reached.
