Switching From Boveda 65% To 58% Question

[Connoisseur Kim]

I recently purchased Govee H5074 Thermohygrometer since I'd like to know the temperature and humidity inside of my tupperdor. When I checked the app, I noticed that temperature constantly hitting 29°C, and the humidity kept swinging between 67-68%. Will switching from Boveda 65% to 58% allow me to keep CCs at 58%-65% 24/7? I know the RH can be 3%+ higher with air tight containers including tupperdor, and the summer weather in my country is very humid and blazing hot, but it's still terrifying to see the RH of my tupperdor being stuck at 67%-68%.

Note.

• The calibration settings of my Govee H5074 are -0.5°C (with ice bath method) and -0.5% (matched to 75.5% using DIY Boveda 75% Hygrometer Calibration Kit for 36+ hours at constant 20~21°C with the help of air con at other room).
• I can't add stronger air con in my room as structure of my room makes impossible to add outdoor unit (unable to control temperature).

I use Govees in all of my coolidors and the office humi and often see the fluctuations you mention. Sometimes it's just the relative humidity of our house. In spring and fall (in Florida) when the A/C is not running very much and the home's relative humidity rises, this drives the office humidor's relative humidity -- especially every time I open the humidity to get a few cigars for the dry-box. I do have 63% large bovedas in the humi but I really don't see much of an impact from them.  

In the coolidors, temperature fluctuates as the swamp cooler comes on and off and of course relative humidity fluctuates with the temperature. I have not found that bovedas really help much with either lowering or raising the humidity. They just seem to operate way too slowly.  In my circumstances where the temperature is low, I'm trying to raise the relative humidity. I've put several large bovedas into the coolidor and really not seen any change in relative humidity and later find them dried out (which of course means they are working but too slowly). My coolidor humidity issues are mostly driven by the age of the cigars and the introduction of new boxes of cigars. I can watch the humidity go up as any new box is added (sometimes by 5 to 7 points) and it usually takes months to reach equilibrium with the remainder of the coolidor contents. In my situation, I tend to rearrange the coolidors and put new boxes in with my low relative humidity coolidor - this makes a much bigger and quicker impact on all boxes. Last issue is to just leave the coolidors alone. Any time I go into one to get a new box for the office humidor or do a 6-month check, I have real issues getting the coolidor's stable again.

My guess is it would work well in the other direction as well. Take an old box or some Spanish cedar and put it in the refrigerator to dry out. Then place it at the bottom of the tupperdor and it should work as a humidity sponge until it acclimates - then repeat with a new piece as the relative humidity begins to rise again.

Thanks, buddy! I'll try this method if 58% doesn't work.

Recent Korean summer weather is hotter than the past (mid 30°C+ with high ambient humidity is more prevalent these days), and this seems to cause RH fluctuation in my stash.
