Essentials LAB pH Up is a concentrated alkaline solution (50% potassium hydroxide) which can be used in small, controlled doses to raise the pH (decrease acidity) of nutrient solutions.
Mix thoroughly and measure with a calibrated pH meter to attain the desired pH reading. Ideal for adjusting large volumes of nutrient solution.
Highly concentrated Can adjust the pH of large volumes of nutrient solution.
Technical Specifications: 50% potassium hydroxide PH: >11.5
Q: How should I use Essentials LAB pH- to adjust the pH level of my nutrient solution?
A: First, carefully check the pH of your nutrient solution. If the pH reading is too low, then the solution is too acidic. Add a small, measured amount of Essentials LAB pH+ to your nutrient reservoir and mix thoroughly. Check the pH level again and note how much it has changed. You now know how much a certain dosage of Essentials LAB pH+ has raised the pH in your reservoir, and from this, you can judge how much more, if any, you need to add to achieve the desired pH level.
Q: The pH level of my solution is already high. What should I do?
A: If the pH is within the recommended range, you should do nothing. But if the pH is too high, then you should use Essentials LAB pH- to adjust it to a lower level, within the recommended range.
