thank you for your opnion! beleive it or not my humididty stays between 54% and 62%. I also on the coast less than a 1/4 mile from the beach. So im sure that has a lot to do with it. I have ordered some flexwatt to increase the are of the hot spot. Again the previous owner had a used a 6"x 4" UTH. I would really like to increase the cool temp closer to 80. Im terrifyed of and RI developing.
