This is my gh right now at 73°/40% humidity. As you can see, it's packed fairly full. Both doors and one window were open today to promote circulation along with a fan. I misted early this afternoon but the dry air from outside brought the humidity down as well as kept the temp down inside . I can keep the temp rather stable at 63° over night these days. But the humidity fluctuates. I would like to keep the humidity constant at around 60-70%. Any hints?
