Too much information and contradictory opinions on the internet so I'm after straight forward answers if possible. Making two enclosures for beardies. Basking light on timer or thermostat? I'm assuming that it would be the same answer for a basking light for snakes? What is best choice for heating at night? Ambient, under substrate or other option? Looking to house two beardies (or 1 beardie and other terrestrial herp) and a diamond python if that helps. Oh and enclosure sizes will be two 1200wx600hx600d and one 1000wx1200hx600d if that makes any difference.
