Keeping lights off temps same as lights on to fight humidity?

Yo guys i'm just wondering about something here, i gotta 5x5x6 tent with 5NL flowering at about week 7.

My humidity when lights on is about 45% but during lights off it can hit 70%, i have 2 oscillating fans in there (always on) and a 350cfm extractor, passive intake, ambient room temps are 72ish.

I tested something and i stuck a fan heater in there for lights off and it pretty much kept the temps identical to day temps (78-80) but the humidity stayed at 45-50% !!

Is it ok to do this? or is a temp drop during 'night' pretty important?

Btw the temps during lights off without the fan heater are same as ambient room temps (70-72)

thanks!

Bump.. Anyone?

put an extra small exhaust booster fan in that runs 24/7 so that the lights dont heat up your room and soil and cause moisture to build up? or put it on the intake, i noticed my room stays about 75 and goes up to 80 because when the lights shut off so does the fan, and then the lights are still giving off heat

I have same problem in summer with high humidity your ballasts and light hood/ lights still give off heat after lights out u need to cool then before sealimg the room for the night, I turn lights off then keep the door open an extra hour and move fans to blow cool air on lights and ballasts untill aprox 1hr then I return fans and close room dropped the temps 10 degrees and kept humidity down to 55 % also I use lights on during night time during summer to fight heat humidity untill mid sep then I move back today lights bcz I like what the cold does to the colours on my blueberry phenos

Hey thanks ! Umm, my lights don't really overheat the tent, max it gets to is 80, and im keeping it at 80 lately cuz i heard warmer temps are good against rot or something? could be wrong but i heard anything below 70 allows botyritis to thrive, even at night. I ordered a cheap dehumidi which i hope reduces the RH by at least 10-15% down to like 35% is this safe?

Until it arrives i have no clue how to stop the lights off RH reaching 65%, but havign the fan heater on in there during night keeps temps around 75-77 and humidity stays dry around 45-50, is it safe to do this until it arrives??

I've already had 2 minor cases of rot in 2 large colas, probably due to me not having the oscillating fans on full for a few days (misinformed). So now theyr all on full blast and i stuck another 1 i nthere too so its windy as shit in there now, this is good right? Sorry if i sound flustered but i honestly am, it's my 3rd grow and iv had rot in all crops but this time its really minor and i still got a lot of nice bud coming on, probly giving it another 2 weeks.

Btw i run a 600 hps and a 250hps with a 125 cfl aider.
