This is a question about mouting a Ceramic Heat low in my vivarium. It would be protected from anything getting near it. The reason behind is that if heat rises it would make more sense to have the source of the heat start low in the cage right? (roughly 10" from the substrate floor) Also, Should I mount my Flourescent inside of the Vivarium? So as to keep the top completely sealed? Or should it be set ontop and screened off? Now is the time to incorporate this stuff into my setup if its ideal for warming and keeping humidity in the vivarium. The top is going to be completely sealed and done in Dura-Ceramic tile.
