Heat issues with UTH and Thermostat

[ckuhn003]

I just recently got a temp gun and the UTH is up to about 88-89. However the cold spot is around 73-74. What would you suggest I do? Put a heat lamp on? What kind and how long should it be on?

I'm having the same issue with my cold spot area hovering around 74-75 so I ordered another UTH and I'm gonna control that with my Herpstat2 and set it for the low 80s.
