Will a black light heat lamp disturb my BP at night? My mom keeps our house so cold, that her ambient temps on the cool side get waaay too cold. I put her cage next to the radiator, and that still wasn't enough, so I put an incandescent black lightbulb in a hood and put it over her tank in the middle, but slightly towards the cool side. If it will disturb her, how else can I raise her ambient temps?
