I have a Pro Panel on my cool side to bring up the temps. Its set on 80 and keeps the cool side floor 77.8 on a cold nights and runs a low % days keeping it 79.6/80*.
Works awesome this way and you can just add a larger water bowel to raise Humidity. I have a 5qt water Bowel from Tractor Supply Plus on my Hot Side and I add a 2.5qt on cool side during winter. I get 58-68% depending how full the bowels are.
