Humidity variance within wineador

[Deezwho]

I live in Central FL so it’s above 70 F in my house all year round. 
 

I picked up a wineador with 6 shelves a while back to store my cigars below 70,  seasoned it, and put in a bunch of Boveda 65% packs. Temp set to 64 F. 
 

I’ve noticed continued significant variance in the humidity readings depending on which level the hygrometer is placed. I now have 3 of them in there and the one of the top shelf reads 67%, the one in the middle reads 69%, and the one on the bottom reads 64%. 

Is this typical for a wineador set up? I assume it has to do with the fact that this one has 1 fan located in the middle of the device for circulation so airflow differences must be causing this variance.
 

Do I need to buy an additional battery powered fan to circulate air up and down to normalize the humidity?

I would have thought having multiple 65% Boveda packs would mitigate this but it doesn’t seem to be doing so unless I just need more of them?

Or should I mix and match the Boveda packs, putting a 70% down in the bottom and a 65% in the middle or do they not work well together in that way?

Or is it close enough to ideal that the cigars will be safe in that range and I’m just being OCD?

Your humidity will stratify in any cabinet. I would expect your RH to be highest on top, but this might be a function of how long your cigars/boxes have been in and resting.

You can get a fan and attempt to equalize the RH across your shelves. Back when I had wineadors I used a fan and it did bring the spread closer together, but didn't eliminate it completely.

I prefer my cubans closers to the 62% mark, so in your case i'd probably put my cubans low and my NCs high.

Personally, I'd just find a range that you're comfortable with and forget about it.

There is more to ambient conditions than temperature. If the home is 70F and the ambient rH is less than 60rH then supplement your rH with a device, Boveda, beads or other and unplug the thing.

Good controlled conditions in an actively cooled humidor is not an easy feat. I know, I have built them for over a decade now.

Good luck on your project! -the Pig
