I did a retro-fit to the other 2 enclosures this evening. Now, all 3 have screen fronts. This means I can turn off the ventilation fans to those enclosures.
Saving a little money and cutting down on the noise in the snake room and elimination the interference to my T.V.
I think the snakes like it or at least they were checking it out when I shut the lights off.
I post a couple photo in the morning. For now it's bedtime.
