New BP terrarium question

[Malum Argenteum]

use the light during the day for ambient temps [...] so currently, until I have this sorted out, I have turned the uth off

I think it is accepted by most keepers that dropping the heat at night on a BP, especially down to ambient, isn't a good idea. Turning the UTH off because it is running warm makes less sense than turning the thermostat down until the desired temperature is reached.
