At an ambient air temp of 72ºF you need to hold close to 80% RH to be equal humidity as 80ºF 60%. If the air is 84ºF you would only need close to 50% RH to be the same as 80ºF @ 60% RH. I agree that there are many factors but the amount you need is a huge part. (BTW the dew point for all three is the same 65ºF what I am pointing out is related directly to dew point. Many just calculate dew point combinations. basically I am simplifying it)



This is the statement I commented on, lights don't actually dry out tanks there is no magic 4th state of water and glass has a very low water absorption. lights change the air flow patterns but your statement is basically flawed.

I still see no correlation in using the lowest recorded temps and temperature recommendations. Especially in light of the status changing among biologists to reclassify Royals as crepuscular (yes there is still debate but it is starting). Averaging the coldest temps recorded each day is simply silly, it is likely only represents 20-50 hours of a month. Using an evening morning averages is likely to be closer, and discard the lowest and highest temperatures.

You really think I thought light itself has something to do with humidity? The heat generated is what I was talking about. Again the heat directed in a tank is a problem. You are making broad assumptions on the setup. You are assuming humidity levels that is unknown. I live in WI my humidity will be a lot different then someone who lives in Florida. Right now the outside humidity here is 22% outside and 64 degrees . In New York it is 60 and 38% humidity. In Minneapolis it is 69 and 19% humidity. Dallas it is 66 degrees and 73% humidity. Now with your reasoning if I live in any of these areas I can put a light in my tank to raise the temp to 80 and my humidity will be perfect. It doesn't work that way. However it will dry your tank out unless other things are addressed to make it work. Again we would need to enclose it and have the right amount of water surface to change the humidity. Raising the temp with a light isn't going to do it by itself.

How can you see no correlation with low temps? Ball pythons do not go out at night? How is it silly? You keep saying my thoughts and reasoning are flawed and silly yet you show no examples as to why. You just seem to read as deep as possible into my comments and say that is flawed. I never thought light had anything to do with humidity. Also you seem to think ball pythons do not go out at night. Again I said a long time ago the high and low temps averaged together makes sense IF they only go out in the morning or in the evening. If they go out at night then lows do need to be considered.
