Through the use of our automated misting system, we achieve a daytime high in the 70% to 80% humidity allowing the cage to dry out overnight to a low of 50% before an 8:00 AM lights on and 1 minute substrate misting cycle. We believe it is essential that the Basins do not experience extreme fluctuations in humidity, that is, that their environment is not allowed to repeatedly "dry out" and then become humid. This seems to be a recipe for creating respiratory problems. Depending on manual misting to maintain humidity for your Basins is a bad idea in view of the distractions everyday life presents.
