Well since this thread is so fresh, and it seems to be worked out for the OP, figure ill ask here about my humidity.
Any reccomendations? Running a 4x4 tent in a sealed 12x12 room. Im at day 24 of 12/12 and I cannot get the humidity down during the day.

I am running 800 cfm 8" AC infinity for exhaust and 600cfm 6" AC infinity for intake, two port holes are open at the bottom also for passive flow.

Two waykar 2,000 sqft dehumidifiers in the room keep the lung room air below 50% usually.

I have a 12" oscillating fan at the canopy, three clip fans under, and one clip fan at the top of the tent. I also am using 1500 ppm of co2

Yet I'm still running up to 67% humidity during the day, and 68% spike at lights off
The red lines are start of day and end of day

Someone can correct me if I'm wrong but I think you want the dehumidifier outside the tent, in the room. That way you're pulling in dry air to begin with, instead of trying to dry it on the way from the intake to the exhaust.

20 degrees isn't that cold but if you bump it up the rh will go down as well.

I agree with this. I keep my dehumidifier outside the tent so low humidity air is drawn in.
In veg I keep a humidifier in the tent for a small boost but I don’t really care If it gets exhausted.
You’d only want your dehumidifier in the plant area if your running a sealed room with C02

I’ve flipped my plants just over 2 weeks ago to 12/12 and the humidity has went pretty high in the 70s-80s, I have a small dehumidifier but it’s not really helping much any other tips to what I can do, do you think I need a better carbon filter set up??

Depends where you are... where i am the outside air is 80% so increasing air flow does jack...

I got a massive dehumidifier and I SLOW the air flow.

You don't need to worry tilcyou get to week 4 really

I've got everything dialed in now Tf but I'll share a past thought that might help with humidity, it's free to share, it might even work great, it could also be a complete waste of time?

Old filter, drill the rivets empty and clean, fill the old filter with disectant or rock salt (idk which most efficient) fix the lid back and stick in your tent with a fan on it and just let it pass air through, both salt and disectant attract moisture, there's maybe better stuff this was just one of those silly passing thoughts I've never looked into it? Lol
