Essentials LAB pH+ 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 and pH- (81% phosphoric acid) can be used to lower the pH (increase acidity) of nutrient solutions.
- Highly concentrated
- Can adjust the pH of large volumes of nutrient solution
- pH+: 50% potassium hydroxide
- pH+ PH: >11.5
- pH- 81% phosphoric acid
- pH- pH: <1.0
- Volume: 2 x 250ml bottles
How to use?
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.
If the pH is too high, then you should use Essentials LAB pH- in the same way to adjust it to a lower level, within the recommended range.
