Switching to a UTH i need some help

[Amp625]

I have decided to switch to a UTH instead of a basking light for hummidity and a couple other things i just want one questioned answered. do i need a CHE or red light for the night time when i start at night the temps drop to about 75 but he'll have the uth on all the time and in the winter i will definatly have a CHE for the ambient temps to be over 80, thanks

ya u can use a CHE or red light on the cool side to keep ambient temps in the low 80's. i do that when it gets cold. just never turn off ur UTH, leave it on all the time.

thanks! so i think right now its okay cause its only down to around 75 but soonn it will get a lil colder and ill get a CHE or red light to boost the night time temps thanks! Also where should i put the probes for the digital thermometer and the T-stat i have a heating zoo med pad

[mpkeelee]

the thermometer should be inside the enclosure underneath the substrate on the bottom of the enclosure right above the UTH. the T-stat probe should be outside the enclosure, some put it on top of the UTH i put it underneath.

If the probe can be effected by a/c or a heater vent then taping the probe against the uth and covering it with masking tape or electrical tape will help.

thanks everyone the thermostat i have right now sucks so i ordered a good one from spyderrobotics right now im back to my old set up with the basking light which is fine, when it comes i will switch back to the UTH and CHE, also one more question why would i put the digital thermometer under the substrate when the surface temp is so difference
