Hi all, currently building a custom enclosure for my BD and just hoping to get some confirmation/clarity before I start scaping the background. I will be forming the 3 sided background out of XPS foam, and then coating it in multiple layers of a sanded grout, and then sealing with mod podge. Given that the basking platform will be formed in this manner, do I need to be concerned with heaving a heating source overtop it? Im still doing some research but right now my plan is to have an arcadia halogen bulb, a 50w arcadia DPH, 12% arcadia T5 uvb, and some overlap of the arcadia jungle dawn full spectrum LED bar. Is there any danger of using the DHP over the thickly grouted and sealed basking area? Thank you in advance!
