What is the correct temperature factor for a typical hydroponic solution? Most meters seem to use NaCl (~2) but wondering if that is at all appropriate for nutrients.
Here is the table from wikipedia
Code:Aqueous solution at 25 °C Concentration (mass percentage) α (%/°C) HCl 10 1.56 KCl 10 1.88 H2SO4 50 1.93 NaCl 10 2.14 HF 1.5 7.20 HNO3 31 31
