Your heavy winter days down there in NC and ours are much different... We'll trade you! lol These humidifiers we're talking about are rated for up to 3,200 square feet and even though mine is running on high 24/7 (and never shutting off since winter officially arrived) in a little 8' x 11' room, it's becoming a constant battle to try and keep the humidity at least 50%. It holds 9 gallons and still needs to be filled about every other day... I see now the humidity outside jumped up to 79% from only 55% earlier today. Since my post a little bit ago, the humidity in my snake room went up from only 46% to 53%. I closed the heater vent in my snake room and i'm keeping a close eye on the temperature in there, so I can adjust my oil space heater settings accordingly. So far, the temperature only dropped from 75 degrees to 73 degrees, but i've been letting it drop to 73 degrees at night for breeding, anyway... I'm hoping the space heater might cause at least a little less dryness in the room than having warm air blowing in there from the furnace. *fingers crossed*
