Re: setup, herpstat, advise
Looks like an older model of the herpstat. I'd send dion at spyder robotics an email asking about it and he can probably help you out with that.
As for flexwatt and stacking the cages, yes and yes. Flexwatt works great with AP cages and they're designed to be stacked. There's should be holes at the front of the cage tops to use pins to keep them aligned when stacked. If your room is warm enough, you could probably use just flexwatt and cover the cutouts for your lamps and be able to keep humidity in the enclosures better as well.
