My first grow and I want to make it impressive

I run a co2 generator and I get no spikes in humidity when I do - if anything the room gets dryer from the extra heat.

Higher temps will result in lower humidity. The temperature will keep the water from condensing.

However, once light turns off, all of the water vapor condenses and humidity skyrockets.

Ever notice during morning hours, as the sun comes up, the morning dew starts to evaporate. As the sun goes down and temperature decreases, water condenses on everything.

The chemical reaction of NG to CO2:

CH4 + 2 O2 → CO2 + 2 H2O

and heat! (and possible incomplete combustion carbon monoxide)

I have an electric heater that kicks in with lights off - never let my temp drop more then 10 degrees, that and I have overkill ventilation.
