When I had the Tower of power humidor, I used the Hydra without issue.
The issue I did have was different humidity levels at the bottom and top.
I wouldn't blame the Hydra, it was more the tall narrow design of the humidor.
I solved the issue by putting a bag of beads on each shelf.
That's the setup that worked for me.

I have the set and forget now, in a different humidor, and I have no issue with it.
I don't use beads any longer, but my current system includes multiple reservoirs and circulation fans.
An extra reservoir in the Tower of Power could be a little cumbersome and eat into the capacity a bit.
