Do you know if leaving them in 90+ humidity will harm them? I live in Ontario (CA) and today's forecast was Location: Toronto Buttonville Temperature: 46 °F Comfort level: 42 °F Dew point: 45 °F Barometer: 29.79 "Hg Humidity: 93% Visibility: 15 mi Although its getting cold I still haven't closed my windows yet because I like the ventilation it gives the room so I also run an extra heater in the room to keep it warm but allow air flow from outside to come inside. Could this be the reason why my humidity keeps sky rocketing? I noticed if I get my room to about 29 Celsius yes extremely hot! it gets really dry in the room then I can keep my humidity at a constant 75. The EE has added a lot of humidity to the tank but I'm afraid a little too much. Any suggestions? A thermostat wouldn't help me would it? Sorry for the 101 questions but you guys are really the best help there is out there.
