Thermostats!

I've looked at many posts regarding this topic and they seem to vary quite a bit.

I received a stack of 321d cages from Boaphile today and they seem pretty well made. All have heat tape installed but I noticed they don't leave an opening for the thermostat probe/s; is this normal for them? Also, I'm curious about how other's have their multi-cage units setup; do you use 5 thermostat probes or a single probe for multiple identical cages?

Thanks again

You drill your own hole for the probe. Folks have their own ideas of the best place put it. And the level of your subtrate will make a difference too.
