| javiersing | 0:ab240102b895 | 3 | // SUBSTRATE CALIBRATION: You have to convert the voltage to VWC using soil or substrate specific calibration. Decagon has generic calibrations (check the 10HS manual at http://manuals.decagon.com/Manuals/13508_10HS_Web.pdf) or you can determine your own calibration. We used our own calibration for Fafard 1P (peat: perlite, Conrad Fafard, Inc., Agawam, MA) |
