Mine is running about 80-82 with light on and pretty steady 74 lights off. You could try running dehumidifier only at light off period. It raises heat, but of course if your humidity already low may not an option. I don’t think your levels are to bad though, I’ve certainly grown with much higher swings in the past.
You could try running a heater but I wouldn’t put it inside tent. It can be hard to dial in without a central air basically.
On a side note, I despise trimming can we be friends? Lol
