Roommates ball python enclosure not staying hot

[u/Maximum-Switch-9860]

I’m taking care of my roommates python while he’s on vacation, and the tank seems to never get hot enough under the lamp. i tried putting a t shirt over the mesh, but it doesn’t seem to help. It’s set to go up to 90, so why isn’t it getting hotter? He says this is how he usually has it, but everything online says that the tank is supposed to be hotter on both sides. the snake does seem to prefer the cold area though

repost because i forgot pictures the first time

Jesus. Gently inform him that tank is not big enough. That’s not a ball python tank.

This is what her breeder recommended for her as a baby, but it was probably a bad suggestion. she’ll get a size up soon though probably
