Anyway to heat up?

Well i've got a infa red bulb on the way but how can i heat up the cool side while i wait? It just got colder here and the cool end has dropped to 75F which is unhealthy.Also i have the thermometer on the substrate.

You might be able to use a regular high watt light bulb.?? try that maybe something like 100 watts.Good luck-ray

UTH hooked to a thermostat. No light bulb. Screen top tank?? Cover 3/4 of the top with something to help hold in heat and humidity.
75 is a little cool. As long as the hot spot is 90 or so the snake will move to where it wants to be.

Ok well i already have a UTH on the warm side and the bulb im getting is 50 watts.and it is hooked to a thermostat.Plus i have a mesh top.The hot spot is about 91F

Oh and im going to use a red bulb so i don't upset her day/night cycle.
