OK, I searched and searched but couldn't find a specific answer I was looking for. I AM going to order some beads in tubes, but for the meantime:
The consensus states that usually, you will add a few drops of distilled water to the foam "puck" in the humidifier. And every 3rd or 4th time, use the 50/50 solution. Do you ever have to rinse clean and let dry the unit?? To the best of my knowledge, the PG doesn't evaporate, so every time you add the 50/50 solution, you are increasing the ratio of PG to DW in the foam to 60/40, 70/30 etc.
Now, this will go away once I get beads, but for the meantime, can anyone answer this?
Thanks.
