When not burmating my snake room has an ambient temperature of 75-80f with a natural drop of a few degrees at night, I then use thermostated heat mats to provide a hot spot of 90-92f below 1/3 of the tub, these temperatures seem to suit the hognose fast metabolism.

Good airflow is a must, this is achieved by melting or drilling holes into the lids, fronts and sides of the tubs. This allows air to flow through the tubs and reduces humidity.

(if you drill holes please make sure no sharp edges remain as this can damage the snake)
