Yes I measure throughout the day. If it’s full blast, there is a layer of fog in tank. Air humidity under lights doesn’t go much over 75%. If I put in lowest setting the air humidity is only 35-40% under basking lights. Excess humidity seems to just leave tank which is half covered by a Rubbermaid lid. When I watched Afroherpkeeper open his grow tent, fog poured out. Also, in their  native environment and in Everglades,the air humidity is extremely high which is what I would of thought they evolved to thrive in? If fogger was to be turned off, under the lights the air humidity would drop down drastically right away and if he’s not in the humid substrate, but is basking like is his usual routine, he will be exposed to dry air, which could lead to shedding and hydration issues. It seems like that is two of the biggest issues faced by Tegu owners, which I would think might be because of heavy emphasis on humid substrate and not air humidity.


If I am off or misunderstood about air humidity please correct me. How often are/should they exposed to dry air? Perhaps I should just use setting in between high and low setting? Also, the fogger is over center of tank over water dish to catch drips, not over the basking spot so it’s not getting drenched.
