Question about re-hydrating beads

[PSUBALL10]

I have a tube of 65% rh heartfelt beads in my 50 count humi. I was wondering how offen people are re-hydrating their beads. The humi was seasoned and has about 40 to 45 sticks inside. It appears to have a very tight seal. I am re-hydrating the beads about every week or so, not sure if this is normal.
