I got my ball back at the end of last year (literally, got it on the 31st of December) and being my first snake I have been learning as I go. One of the biggest issues for me was maintaining the heat. Once I got that figured out the humidity went out the window also and it has been a struggle to find the right combination. This looks great, I am trying it now in hopes that this will be the answer that I needed.
I live in Arizona and summer is on it's way I am now wondering if this will be too hot for my ball during then. It was about 10:30pm when I was working on this with the cover off and putting the bedding in with the uth on and it had climbed up to 104 by the time I was done about 30minutes later (Granted my thermostat is not as nice as the one shown in your tutorial).
Also before I forget, thank you for this lovely post, it was informative, helpful, and greatly easy to follow :)
The tank looks even better with it blacked out than it did before. I suppose if it does get too hot later in the season I will just remove things bit by bit until a good balance is reached...
Again, many thanks for this awesome post!
