Your humidity jumps at lights out because the temperature drops from lights being off. So the air loses its capacity to hold water and thus your RH rockets.
I would just run the exhaust fan constantly. Does the basement become humid? If it does you'll have to open a window or something to let the RH drop. Or get a Dehumidifier to turn on during lights off.

dehumdiifer inside the tent will work. Set it to work full time during lights off.

Yea I was thinking about running a 50 pint dehumidifier inside the tent with a trolmaster but I don’t know if I’ll run into other issue doing that

Why do you need the Trolmaster? I mean it's fine. But you can just put it on a timer if it has a n auto on setting.

I use Trolmaster as well, but the humidity relay is kind of useless. Lol. I use mine to run a fan. They are only good for 10a so constant heavy use by something running 7+ Amps I don't trust it to be reliable.
 
Me personally, I would definitely put the dehumidifier in there and exhaust the heat but wht I just found out by listening to Kyle Kushman is tht if you turn your fans off whn the lights go off tht drops ur humidity a little. NOT EXHAUST fan just fans sitting in grow!

Makes sense since the plants would transpire less if the arent being blown on.
But I wouldn't do that. Sounds like a recipe for PM and other fungal issues. I'd just run the dehumidifier safer.
 
No doubt I agree I just ran across the vid and thought I’ll share the knowledge. I also tried it, and seen the difference but I like my fans blowing he help keep my nighttime a lot cooler

a 50 pint dehumidifier may create too much heat and may be overkill for that tent. I run this in my sealed 6x6x6.5 and love it:

As others have suggested before, venting all the time will help and I also believe a smaller dehumidifier will serve you well.
