All :
I know UTH is what's recommended/preferred by most folks here, & that's what I'm using. & I have been told repeatedly here that corns don't need to bask. I do not have a light for the cage at all -- the tank is in a room that gets indirect bright sun several hours a day, & in the evening, it's dark.
Naagas, I am reading Kathy Love's Corn Snakes: The Comprehensive Owners Guide, & Chapter 3 (Basic Caging & Housing Requirements) is exactly to which I'm referring, in the section HEATING. On page 50-51, after discussing heating pads & heat tapes & heat rocks, she then says:
"Spotlights or hooded reflectors may also be used to direct incandescent light to a special basking rock or branch that the snake can utilize easily...The basking temperature on the perch site directly under the lamp should be in the 90s F. This slightly "too hot" spot allows the snake to thermoregulate properly to reach the temperatures it desires or needs, but also lets it move away from it when warm enough, just as it would do in sunlight."
I have been paying attention since before our snake arrived to EVERYONE here who told me no bask, no bask, no bask -- I was just surprised to read in what is apparently the corn snake Bible such specific instructions for setting up a spotlight & basking rock/branch, which implies that it's recommended, esp given her claim on page 50 that:
"Basking in sunlight is by far the method [for thermoregulating] corn snakes use most often. They can count on the sun on most days of the year in the wild range."
