I have a sterilite tub for my snake and am running into issues keeping the air inside above 75 degrees. I live in Washington state so it is pretty chilly. Currently the only way for me to maintain a temperature of >75 degrees in the tub is to set the thermostat for my whole apartment to 75 degrees. This is making me somewhat uncomfortable and has raised my utility bill considerably. So I am wondering if there is a good way that I can raise the temperature of the air inside the tub without heating my entire apartment.
