Struggling with lights off rh.

[Greenthumbgrower1986]

I routinely run 65-70% RH day and night and have not had any mold, rot, etc.
I'm attributing that to good air movement and exchange and maybe a little luck.

Have very good air movement. I'll try moving the intake to another room and see what happens tonight. I'll report back tomorrow

You said the tent is in your bedroom? --How's the humidity in that room? Reducing that in some manner should help.

You also mentioned "the window is always open" perhaps too much outside RH especially at night and early mornings. Sure the air is nice & cool, but moist too. Close that window more often, perhaps?

Defoliating definitely helps. Also watering exactly right when the lights come on. Water less often maybe? --like have a more substantial wet/dry cycle, assuming not in DWC.

So I tried intake from another room last night that has windows closed, and closed bedroom window yet still the same. I'm using a 25l pot so maybe the soil. I'll defoliate some today and see how she goes

I've given her a hair cut.hopefully will help.

Try throwing that oil heater in and raising ur temps at night a little

Have you tried switching off your intake fan at lights out? Have it running on the same timer as your lights.

Yes I have only reduced it by 2%

Testing where you intake from is next on the list then.

we could be giving you ideas for lowering it and you could be intaking 70% lol.

Well thats why we asked what the house RH is,cant do shit if thats also high.

Maintained a neutral temperature differential, then Guage the RH spike and add a dehumidifier.

As Relative Temp decreases the amount of water the air can't hold becomes less and as a environmental response the excess moisture raises humidity

So I left some rh monitors in all rooms and they were all the same this morning, 59%. I've tried in taking from these rooms yet still temps in tent at night are 21/22°c and 68% . I've also tried reversing my intake so air is extracted through bottom and top of tent, and I've tried shutting off intake completely, I will try the oil heater tonight and see what happens, I have 3 fans in the tent running 24hrs so I hope the air movement will be enough for the rh to not cause problems

This!!!
Nothing wrong with high humidity if good air movement.
