You can mix active and passive humidification, but you have to be very careful about it or, as others have pointed out you will just saturate your beads. I know people who do have both active humidification and HCM beads togeter, but I have never seen it done with the Aristocrat. Bob's Set-And-Forget system is awesome.

You can put HCM and Heartfelt beads in the same humidor. The HCM beads will end up at the same RH as the Heartfelt beads. However, for the purpose you mentioned I would go with either Heartfelt or HCM but not both. I think its more difficult to manage two different types of beads than it is to manage one.
