Condensation in milk snake tank!?!?

[DangerNoodle]

Hi! So my baby noodle moved in today! She's a 7 month old pueblan milk snake. She's burrowed down and not quite felt happy enough to come say hello yet so I'm leaving her to settle but I noticed a build up of condensation in her tank before
The substrate is dry and fresh out the bag so I don't understand what it could be can anyone help?
Attached are pictures of her tank

I think you need a bigger enclosure, (or 2 hides at least, one in the warm side, one in the fresh), and a way to control and read the temperature of that heat mat or you'll have a tragedy. It's very probably that the condensation comes from the water dish, as looks like there's little ventilation in the container.

Its likely the warmth in the tank causing the water from the dish to evaporate. Not a big deal if the humidity dosent go too high. If it gets too high you can always put in a smaller dish

You control humidity by ventilation flow. With the air hole on the side of a container you have higher humidity. If you put the air holes in the top of the lid the humidity will drop.
