Ice Crytal Gel
I have a 150 count humidor that I got recently as a gift that came with a couple of those rectangular humidifier blocks. I would prefer not to keep those in there because I read they get moldy real easily. So, I replaced them with a 4oz jar of Ice Crystals to maintain humidity, but I notice that when I just have the ice gel in there, the humidity starts to dip. To compensate I put one of those blocks back in the humi on the bottom shelf. Should I put another jar of Ice in there? I don't want to over-humidify, but I don't want to keep the sponge in there either.
