Thank you so much!! I made 11 holes, do you think that would be enough? I'm so surprised how well the tub keeps the humidity~~~It even slowly grows because of the water bowl!!! I want to move all my snakes in tubs lol!!!!It's really great!!! I should find a place to sell my glass tanks lol!!! Oh and may I know why we should always stick the probe to the heat mat instead of putting it inside their hide? Is that because it's more safe? Thank you so much!
