I just got the ihc 200 controller and did a simple "wet salt in jar" test to see if it hit 75% and it was 0.3 over so adjusted on calibration setting. But 2 days later showed big swing compared to my hygrometer so I checked again today with the wet salt test and its now showing 80% so 5 over. Can anyone help me figure a way to keep it accurate. I had it hanging at about 5ft height and 2 ft away from direct light, i dont understand how the accuracy went from 0.3+ > 5% in just 2 days
