Re: Starting to have issues with the Vino's RH lately....
What is the current temp set to?
You may want to use a Johnson's temperature controller as well. If you set it to closer to 70 degrees, it will turn on/off less frequently which should reduce the frequency of wide RH swings.
Also, adding fans will help to evenly distribute the RH throughout.
Sorry, for reason I thought you said you calibrated your hygros - if not, Ranger and Apoco are absolutely correct. Replace the batteries and calibrate them first so we know where we stand.
Hygros do "drift" and weak batteries can give unfavorable readings.
I hope this helps
