Hello peeps,
Need to know if you can use solution for calibrating your pH-meter in your DWC reservoir, as pH upper or downer?
The reason is it's impossible buying the real stuff for hydro where I'm at, and I'm not too comfy using vinegar.
Ingredients:
For the pH 4.01 solution: Potassium Hydrogen Phthalate
For the pH 7.01 solution: Potassium Dihydrogen Phosphate and Disodium Hydrogen Phosphate
Thanks in advance for any input!!
