@blacklake, Hi there, yes, please excuse my delay, but I somehow missed your reply. What type of soil moisture sensor did you use and what was your experience with that particular model? I am asking because I have never encountered a "hobbyist" grade soil moisture sensor that did not degrade rapidly, the conductive ones did oxidize even in AC pulsed mode, the capacitive ones encountered massive signal drift and even my diy solution did drift, so it might be my slmore my soil and less the sensors. I know of a few industrial solutions like porosity pressure or colorimetric heating, I just haven't found a solution for home applications. Or for that matter an affordable professional kit.
