I put more holes in my tub and my temperatures on the cool side are at about 77 now with my space heater and the hot spot is floating from 89-91, so I have almost everything set but my humidity. My humidity has been steady at 70 which is the lowest I have gotten it to stay at. Should I still put more holes in the tubs, or is 70% alright? I figure it's a little to high so I can easily put holes in the tubs and hopefully lower it.
