@CamoSutra thanks for the info. The beads are spread throughout. I actually have them loose on the floor with a large bag near the back to catch condensate, two pucks near the bottom front, a large tube two spots up in a drawer, a large rectangle in the back below the fan, a large tube on the shelf above the lower drawer, a large tube on the next shelf (other side), large tube in the next drawer. So they are EVERYWHERE. It's still at 60% (a hygro on the front of each drawer) so I think the beads are just playing catch up.

You can't see in the photo to well but the hygros read 60%/67F while the display reads 57F.
