How do you keep a snake during the summer?

[Stewart_Reptiles]

im keeping a 10 gal inside a 40 gal. (i know weird) cuz my 40 gal does not have a door yet. and i didnt realize how small the snake is compared to the tank. i have a medium uth under the 40 and i keep one side of the 10 gal on top of the heat pad. i only use it at night but since the heat pad gets too hot, im using a timer to turn on and off every 30 min since i dont have a thermostat yet.

the temp of the room is around the same as the cage's temp

That is an accident waiting to happen, you must buy a thermostat to control your heat source. You need to do so to prevent severe burns and possible fire hazard and house fire.

A thermostat is the single most important piece of equipment when it comes to husbandry, don't delay if you can't get it soon get a dimmer from Lowes or home depot.
