So different RH packs will fight I get it but won't the 320 gram 75rh buried at the bottom of my leaky wood 300 count box merely serve to charge the 8 gram 62 rh packs distributed around the middle and top shelf?
The systema and Ammodors don't have mixed packs but I suspect the wooden box mainly leaks humidity out of the bottom as when I leave it on the desk for a while it leaves what appears to be a condensation print. It now sits on zip bags on the shelf.

Everything I have read on this is doing much rh levels. Mixing the gram sizes is ok. I have only used the same rh, and I be use 65 rh in my cooler and it's pretty much right on.

It may case thunderstorms in your humidor.
