What humidity should a seasoning humidor be at?

I don't use a hydrometer, that would be crazy. I just use a sling psychrometer and an altimeter. I installed a Johnson control system and a series of sensors to monitor humidity, temperature, CO2, TVOCs, as well as small particle laser light scatter sensors and a beetle occupancy sensor. All data is sent via wireless to my multitasking iPad.

Damn, that's a hot setup!
