Heat issues with UTH and Thermostat

[Binkskii]

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.

If i didnt have a herpstat2 or an extra thermostat do you think it would be worth the trouble? Is it THAT bad for the temps do be where they are?
