I put Heartfelt Tubes in my Newair wineador. I have 4 65%, 2 on the bottom of the unit, 1 in the middle, and 1 near the top. I initially had sprayed them and was gettting high readings so I dried them out. I have 3 calibrated hygrometers init and I’m getting reading of 64% on the bottom, 68% in the middle.and 70% on top. Is it normal/common to have those kind of variances in a wineador? Does it take some time for the Heartfelts to get the RH in the target range?
I have a tower and have the opposite problem, higher on the bottom, lower on the top. It's bigger than your wineador so I have 2 fans on a timer both blowing up. Still doesn't even it out completely but makes a big difference. Mine will range from 62-70% depending on the time of year. I used to worry more about it but haven't ever had issues with how they smoke and have never had mold.
