I'm constantly worrying about the flexwatt/thermostats in my snake room. A couple of weeks ago I ordered more tstats so I could begin outfitting my racks with backup thermostats that will turn the heat tape off in the event of primary thermostat failure. Due to recent events I'm about a million times less comfortable with all of this rigged up flexwatt in my house.

I've seen a few people comment about "some big breeders" who use ambient temperatures only with no hot spots. Are there any of you who are doing this with success, or can perhaps point me in the right direction?
