Circulation Fans vs Humidity

How many circulation fans do ya'll have running? I only have one at this moment and one on the way. I don't run it constantly ATM because I'm trying to keep my humidity up during early veg. Currently, my fan is mounted above my light facing downwards to the back corner. Pushes the hot hair down into the canopy, but doing so really depletes my humidity. I know I will need one pointed at canopy soon, need to get that air movement around the little ladies.

How does one find the balance in tents? Am I over thinking this?

I have 3x8" fans in my 4x4 as well as the 6" exhaust fan.

2 fans blowing slightly above ground level and 1 fan at canopy level. Considering its winter here and dry as balls I still maintain 50% RH with no humidifier.

EDIT: I've found my exhaust fan speed to be the biggest factor in maintaining RH%

I just have one regular 12” hanging from the top right corner of my 4x4 on low, it works great.

Ok, seams like for me its more environmental then. My exhaust fan only runs when temps or humidity goes beyond my set points. Which is 75 degrees for temp and 70% for humidity. Running no filter, hood plumbed in. I have 6" exhaust, and one 6" fan. another 6" is on the way. I need AC Infinity to release there circ. fans asap so I can buy and use with my controller. there is no direct air movement around my canopy now.
I have a humidifier running 24/7 on low. that way i can go 24 hours before I have to refill the reservoir.

Most days my temp at canopy is around 68 degrees and my RH is about 50%. On average. Somedays higher, but that's all environmental.

I know all this will change as my weather changes in the coming months.

Just stick a few more circulation fans in.
You don't want PM ey.
Plus more fans equals more Watts equals more heat.

I usually do a 16" oscillating wall fan every 6 feet or about 2 meters of wall space or so up high staggering wall fans low as well to blow under canopies without needing floor fans.

Mounting the wall fans low in oscillation will give the lower part of your plants lots of airflow and also help ward off bugs trying to hangout in your pots/growing medium if you have a powerful enough fan.

You want passive airflow where your not blasting the plants directly with the fans. More is better than less, less airflow your asking for more stagnant loving pests, diseases and ultimately an inconsistent environment.. If you notice plants are whipping around and you "over do" your fans then just turn them down to low/medium power.. Redundancy is important too.. Always plan for any piece of equipment to potentially fail at any time.

Two is one, one is none..

I run one 12in fan on the outside of my tent thru the bottom vent flap but I found if I keep the temp the same inside and outside the tent the RH is easier to manage.

I have 2x 6" fans in my tent, one on each end. They're not on at the same time though, they alternate hours. I also have both exhaust and intake fans that are controlled by the same controller. They have a minimum low setting and trigger by additional heat/humidity depending.
