Depends on the rillo.. I've had some that are dry cured, and others that aren't.. Honestly, I have some that I buy with the sole purpose of storing them in a humi for 3-4 months before even starting to smoke on.
I wouldn't store dry cured in a humi, but the non dry cured rillos def need humidification. My experience is go low on the RH. 69-72 is too much. go 65, maybe 62... they tend to burn much better with lower rh.
