Thank you for the ideas!
I'm not able to put the snakes in tubs or a rack setup right now. My mom doesn't want them there. I have the tubs, but she wants them in tanks instead.
So they are in glass tank--one 20 gallon long, a 29 gallon, and a 40 gallon breeder. I have all of the screen tops covered in layers of duct tape and aluminum foil to help keep humidity in.
I have one of the snakes on newspaper, the other 2 on Aspen shavings.
Hot side temps with the heat mats on is typically 85-90 degrees (one tank is 85, one is 90). I have to go check the hot spot on the 29 gallon to find out what that is, but I'd guess 80-85.
How do I insulate the sides? That does sound like a fantastic idea.
I've tried running an extension cord to the living room and plugging the space heater in there. When I do that my sister's electricity in the room next to me gets shut off, as does the electricity running to the light over the stairs, near the front door.
Our house is old style and the electricity is very awkward, according to the electrician who came out a month or so ago and examined everything.
Umm...what else...Humidity is roughly around 10% if that. I keep spraying, spraying, spraying, but the lights I put over the tanks to try to keep the heat up dry it up minutes after I spray.
I'm afraid to spray without the lights on because it will be too cold.
I also have a fish tank (20 gallon tall) in my room. That is the reason the humidity is at %10. I'm lucky for that.
I'm worried to put the water bowl over the hot spots because then the snakes will be cold.
Thanks for all the help. I'm trying really hard, but I wanted some other opinions.
