Good luck!
I deal with the opposite over here in a English west country wet air winters. Besides the night frost it's such thick air I have to watch for fungal problems constantly and spend an arm and a leg on airflow!
Just have to get the girls all nice and snug! Got anything to make them more comfortable?
I got something for the heat and its called turning my light up I'm only running my hps @ 150w's right now so she'll jump up a few degrees lol Fubared on the humidity though,Have 4 open containers of water and still can't raise the thing past high 20's
