Hi Kosher, no, this is just a converted refrigerator. I guess my use of "reefer" is apparently a so-Cal thing, as you're not the first to think I was talking about a walk-in (I wish....but then, I wish for a true cave, underground....!).
The issue I'm having is that the programmable humidifier nominally goes to 90% - then shuts off when it's sensor registers that maximum. The trouble is, the wireless I have is registering lower.
So, if I presume it's the case of an accurate remote sensor and a bad humidifier sensor, I was hopeful of finding a way of gaming the system somehow by increasing the humidity while keeping the humidifier rolling...perhaps, a separate level of the refrigerator that gets some of the humidifier humidity, but increased by some of the methods you suggest. The good news out of this, I think, is that I had wanted a drying chamber at 55F and 90-75% RH, per some thoughts gleaned from Linuxboy. I strongly suspect I have strata of different RH's within this one cooler, and that would be ideal, for me.
I know that if I simply put a pan or something like this by the humidifier, it will only shut off "sooner," not achieve a higher RH than 90%. More than you asked for, I'm sure. On the highest nominal RH, the good news, or at least better news, is that even the remote sensor is now registering 87%, but it sure took it's sweet time to get there. I actually do not trust either of the sensors, and will back them up with an analog, calibratable hygrometer. Hopefully, it will either show one of them is spot on, or if not, that it is consistently off so I can work an an assumed difference.
Linux, if you're watching - presume an RH in the high 80's will mean b. linens will likely not do so well, yes? Based on some other comments you made - basically, a simpler notion of tomme, not the kitchen-sink idea; emphasizing mycodore/derm - I get the wisdom, so am not too terribly disappointed at this juncture if the red-smear characteristics are muted, or even almost nil. But it would be nice to know the field of play among Geo, P. candidum, KL71, mycodore/derm, b. linens, for different cheeses, or different variations on a given cheese, with an RH in the high 80's as opposed to 90, or 95%.
