I'm considering upgrading my PVC Adult and Subadult racks to the the ARS 5040 & 7020 or 30. I keep my snakes in an open floor basement that is not specifically heated with the animals in mind, although it does typically stay between 68-75 ambient due to my primary home thermostat.
How well do the ARS racks work in an open room like this with a lower ambient and a bit of temp fluctuation?
