MiaFLSurf,
First, PM me for my copious historical notes on my wineador. I don't have time to condense them and clean them up for public consumption, but I'll be happy to share then with you, warts and all, if you like.
Second, I've made just about every mistake you can make with my wineador, a Whynter CHC-251S, and have finally arrived at a happy place. My advice is:
1) Add a wick to the drain hole. You stop air-transport (and thus humidity loss) but still allow water condensate to migrate from the inside of the cabinet to the outside.
2) You will still get condensate running to the floor of your unit so throw a bag of beads down there and check it weekly.
3) RESIST ALL URGES TO ADD TOO MUCH WATER. Sure, you need to add water now and then, but it's far less than you think. I got to the point where any water I added simply evaporated, then condensed, then flowed to the outside of my unit, and things never achieved equilibrium. It was shedding water the water I kept adding! It has now stabilized at 65%-66% rH and will go NO HIGHER. With this system, and my locations and environment, that's just the way the physics work. If I add more water to try to achieve 70%rH I will destroy the equilibrium and ultimately fail. (And before anyone says it, yes, 66%-67% is perfect!)
4) Get at least 2 small computer fans and have them running half the time, preferably in interfals. I can show you how. You need air movement to avoid humidity stratification.
5) Ensure there's an open area on each shelf to allow more air movement between shelves.
5) Make damn sure your hygrometers are accurate and steady. I've been using many CAO Tags (no relation to the cigars) for wireless humidity and temperature readings and they "drift" every couple of months, making me think I need to add water! NOT GOOD! I now calibrate them often against some simple digital dial versions I know are true and steady. (Note that with _any_ electronic hygrometer, you will only ever get to +/-2% rH anyway, so don't get carried away.)
6) Take lots of notes.
Some day I'll retire and build my Humidor Masterpiece. It will have a separate enclosure for the Peltier cooling unit where all condensate drips into the active humidification reservoir, an active humidification system, fans to drive the cool humid stable air into and around the cigar inventory, and PID Controllers to manage everything. I recently "scienced the sh*t" out of my electric smoker, so I can certainly do the same for the humidor.
