I'm wondering, if i use a solid lid on a 41qt container, and heat the enclosure with 2 heat lamps from above, would this be a feasible idea? the lid is not clear, and light does not enter the enclosure, yet the lid becomes very warm, and seems to warm the enclosure quite well. Also, will the ambient air inside the enclosure heat the bottom surface enough for my monty? or do i need a uth as well? I'm using one at the moment, but if i use it in conjunction with my 2 lamps, the surface temp reaches up to 100 degrees! ouch!
