Tegu Enclosure

[John1982]

I guess I just don't understand why anyone wouldn't want to provide supportive conditions year round. A lot of the ones I've seen that were maintained with optimal conditions year round still remain active, or at least go through a much shorter and lighter brumation. To each their own then.

That's different from my personal experience. Mine seem to take their cues more strongly from the photoperiod than actual temperatures. They start going down in August. Temperatures are still getting into the high 90s, or even low 100s, during the days. If I maintained them in "supportive" conditions as you put them then I'd end up with half starved, or dead, tegus by the end of the season.
