I think I may have accidentally cracked the underside of my glass cage by means of a rapid temp. change when I sprayed water in it. At first I thought I had too much cypress mulch piled up as bedding and that retained the heat and caused the crack. I have sealed the crack and will just use a heat rope for that cage, but I don't want my other two cages to undergo the same damage. What is the best way to mist and water down a glass cage while still using the UTH's? Spraying hot or warm water would seem to do the trick, but is there a certain substrate that will keep the water from touching the glass but still be thermoconductive? Also, I find that cypress mulch sucks at retaining humidity, despite numerous claims to the contrary. I think that Exo-Terra's Jungle Earth combined with some eco-earth coconut soil works best, what do you guys think? Also, are dry sheds or shedding in bit's and pieces a direct result of insufficient humidity and does zoo-med repti-shedding aid help any? Thanks for all the info in advance.

if your tank cracked when the water hit the spot where the uth was, then the uth must have been defective and got to hot.
