A uth must be plugged in and regulated by a thermostat. ..uth unregulated can get well over 110 and can burn snakes.I highly recommend any herpstat brand thermostat....there are cheaper routes like hydrofarm. You could also use a lamp dimmer in the mean time... I switch a few of my species to cypress come winter here in Minnesota. . You can mist it and it doesn't mold....if you are located in the Minneapolis area there are a few really good reptile shop that have everything you need there...one is twin citys reptiles...they have ve thermostats in stock (very good models to) and all your substrates...there are some very knowledgeable keepers and breeders there. Are you gauges analog or digital?
