What I've been doing lately is I keep two seperate tubes in my desk top and two seperate trays in my primary cooler of 65% beads. I only add distilled water as needed to one tube/tray to regulate RH. That way if there is a spike in heat or humidity my "dry" tube/tray can soak it up.

Now I understand that, as advertised, the beads should self regulate and equalized over time, but I open my humi and cooler usually twice a day and I've found there has remained enough of a difference between the tube/trays that my RH has been really stable lately.

In my 2'nd cooler I have the little gel jars that should stay at 70% but them roam all over the place. I am working away from those.
