I live in an apartment with no control over the heat. Over the past week it has been really cold up here in Toronto so the super has cranked up the heat in the building :angry: and my humidor temp has risen as high as 74.5 degrees during the day. When I check in the morning it is around 72. I have decided to freeze some distilled water in a small tupperware container and place it in a corner of my 100ct. humidor in order to get the temp down. Hopefully this will work.
