I have a 100W ceramic bulb, and it is keeping the air temp around 88-92 degrees, however when I put my hand in my baby ball python's tank the substrate doesnt feel too warm, and neither does his hide spot. Should I get a UTH? If so what is the best brand? I have heard T-Rex Cobra's are good. Also should I get another lamp but for use at night for viewing? I am asking because I dont want to overheat my snake. Thank you!
