Day/Night temperatures in rack system

Hello, I'm pretty new to the hobby and just recently acquired some rack systems. I had a basic thermostat from Petco running them with 90°F hot side 80°F cool side. I just purchased and installed a Herpstat 2 redline thermostat and noticed it has a night cycle option. So, basically my question is do you guys use a lower temp night cycle or not? If so, what do you have it set to? I set mine for daytime at 90° hot, and night cycle from 8pm to 7am at 80° hot as I found in the instruction manual that came with the Petco thermostat. Let me know what you guys think and what you have your racks set to.

Thanks in advance!

No reason to drop temperatures.

You are setting yourself up for issues keep you temps steady 24/7, you can change your temp if breeding but even that is unecessary.

ok cool, thank you. I actually ended up setting it back to 90 constant before I went to bed lol.
