ok admittedly new to all this but always willing to learn 
Had heard of flex tape, under tank heaters and even Kane mats ..but RHP...please do tell. We are building a 4x2x2 enclosure for the beardies and as we live in "the great white north" & heat with wood, keeping a warm cage at a low cost is a priority; especially since if we work this cage out, a cage for the daughter's Egyptian Uro who likes a MUCH warmer cage is not far behind. Hubby is an electrician so wiring stuff is his dept I am just the researcher so please incl any electrical stuff too so I can pass it on to him along with any no nos since he has never done this type of thing before(I dragged him into the repti world)
Was originally thinking that we would simply insert glass/plexi panels into the bottom of the cage so we could use undertank heaters for substrate but this sound easier? And would the panels be able to withstand the weight of the sand we use as substrate?
Also would like to make the cages mobile, so was thinking of mounting castors/wheels underneath but would I need to then mount a small square on each bottom corner to attach the wheels?
soo many questions and more occurring every minute.
