What system do you use?
If you could use DWC or other hydroponics, it would raise humidity naturally…

Pail of water and a couple wet towels hanging.
Just leave the end of towel in the water.
Kinda basic but will raise the rh a few points.

I’ve just put bowls of water in before and it works to a certain degree but the towel bit is brilliant!

I use humidifiers, but overall its dry here. It says its your first post so let me welcome you to OG!
If you search threads theres a guy on here used a clip fan on a 5 gallon bucket, said it goes thru a gallon a day.

Hello, @GirlScout1985 - and welcome to overgrow!
As others have pointed out, a container of water is a simple (and passive) way to slightly raise your humidity. I would suggest that you also aim your oscillating fan to blow across the top of that water container to increase the humidity even more.
How low is the humidity in your tent?

I experimented with cloth pots, I could add 10+ %. But you need to control RH levels after lights out as it shoots up.

I’ve done quite a few different setups for humidity, but I like this one I did last night. Its in a 2X4 wood chamber(I know not ideal) and the humidity went from 26% to 47%.
The fans are pointing downwards into the container so they blow air out the other side. I figured the fans would last longer getting less direct humidity that way.
And this one in my 3x5 closet is different.
The heater in front blows warm air across the water, past the rags, and behind each rag is the intakes for an air purifier so it sucks the air in and blows it straight up.
I put a little peroxide in the water, or the rags will get moldy and gross.

I put one of these:
Into one of these:
And fill with a line from my RO filter directly into the jug. I monitor with a webcam, and I add water from outside the tent by turning a 1/4 turn valve.
You do not need a fan to blow the fog around if you have decent air movement in the tent. I originally implemented IP67 rated fans on each of my fogger setups but they are (in my case) unnecessary.
I also pulse my exhaust fan on 15 seconds, off 45, on the lowest setting that will scrub odor. Helps to not remove so much freshly generated humid air.

U a mudvayne fan? @LD50 ?
Wet towels work well BUT you can buy humidifiers cheaply. There are 2 different kinds of humidifier ultrasonic and evaporative. Ultrasonic is the quieter of the two and what I personally use when needed.

No, why? After a quick google you’ve gotten me quite curious!

It’s strange… when I 1st started I added humidity… because my plants were NOT uptaking correctly… after raising Temps under led now humidity constantly rises unless I need to feed (they’re dry) etc… I constantly fight humidity with my ac infinity inline fan… It kicks on at 60 percent… so it’s always getting to 60’s

LD50 was the name of their 1st hit album… has the song “dig”
I struggle with high humidity. I’ve got a 12l floor standing dehumidifier I use when I’m half way through flower.

I’ve stopped chasing the perfect vpd if I’m honest

Me too… especially under led… it’s all hogwash… outdated Info… the margin is much more divided under led… so higher temps and lower humidity for a proper vpd… I’m at 88 degrees tops… and 85 minimum temps… and 45 lowest and 60 highest humidity (lights on)

Ha that’s great! I first hard of the acronym in a HAZWOPER class. “LD50” is of course short for Lethal Dose (50%)… the dose of something that is expected to kill 50% of the population being dosed. Heavy acronym, always stuck with me.
IDLH is similarly fun.
