I do have a heat lamp but i had no problems with humidity before the insulation, i just put the insulation on yesterday and all day today i have had to mist like every 2 hrs.
A. Before putting on the insulation thats what i did, misted it about 2-3 times a day and it kept really constant at about 50% humidity.
B. Ok well i do have a humid hide for her, with moss in it and she goes in there whenever
C. I tried a room humidifier but it was hard more "me" to live in, made my whole apartment muggy.
