So as some of you guys might know I posted a thread about building an enclosure for a lizard and the plans fell through a little bit with financials lol... (long story..) But I am still considering treating myself to a nice Rat snake, possibly Albino Radiated, or Leucistic of some sort. Anyways I am going to be using a tote for an enclosure, I will be expanding ontop of it with another tote the same size eventually but at first I will be just using one. Only problem I'm having is I'm concerned about heating the enclosure.. as the tub is a sturdy material, I am not sure whether using a UTH, or basking bulb would be more efficient. If I used a UTH I would be just cutting a hole in the lid nd hanging a low wattage bulb in for a photoperiod day/night sched. If I used a bulb I would be cutting a section of the lid out match a piece of mesh or screen to so that I could set a fixture on top hang it over the opening. Ideas on heating? As the material is like a plastic, so with little ventilation humidity should stay steady in the enclosure with the substrate I will be using.
