I know there are many posts about temperatures on the Internet about red tail boa痴 however I just need to ask this what is the lowest temperature that the colder side should be at I知 pushing 74 1/2 to 75 in a glass enclosure? Without buying a new bulb for the cold side what are some ways that I can get it up to that degree if it needs to go up that high I do have a heat tape And another thermostat that I can use?
