So, I dried the beads.
I put some of each in a tupperware container with a hygrometer. Both read about 40%. So, I assume I maybe dried them too much? Retraining necessary?
Or should I put them in the cooler as is and let them soak up some moisture first?
It is possible the seal where I put the cooling unit is not great. I'll pull that apart and seal it good, too.
