I think the only thing I would change is the location of the accurite and the probe. The probe placement makes sense for the kind of hides you are using but I am sure the acutal temp of the tank under the substrate and hide is much higher, if they snake ever happened to go there...yeah
Also I would move the whole accurite unit farther to the cool side and closer to the ground.
Just my 2 cents! Great viv setup and I agree, sticky!
