I have a three foot vivarium which is 25 inches high. Here a googled picture but the dimensions (lamp inside the guard) looks right ish compared to my setup :
The lamp I am using :
The probe of the pulse stat is in the middle ish of the viv. WHen I set it so the temperature just above the hide is 85F I am even unable to touch the guard its so hot (110+)
For now I lowered the temps to around 80 and moved a king snake in which is fine, but for a royal I obviously need higher temperatures so before I finish up the stack part of the viv for the royal I'd love to know what the best cause of action is here ...
It seems that it is impossible to get wider guards and most shields I found seem quite wide so I am not sure if that will all work ...
I am tempted to get someone to build me a custom guard which is a lot wider (I THINK I have about an inch and a half on the sides between bulp and guard) but I thought I rather ask ...
