High Humidity

I have found even cleaning the prefilters on the carbon exhausts makes a huge difference. 2 or 3 notches on the fan almost in difference. Just some ideas. Or even remove the prefilters or even the carbons as needed. But as you know you cant lower the humidity below ambient. The lights raise the temp and that helps a little with humidity. Week 2 3 4 5 I think you are OK it is 6 and on that gets trickier.

Some things that come to my mind:
- Dirty filter on the dehumidifier
- Maybe needs cooling gas refilled on the dehumidifier if it's older than 2 years
- Exhaust fan or carbon filter dirty, resulting in low ventilation
- Open all the intake flaps on your tent
- Leakage in your walls, floors or windows which lets in the outdoor humidity. Although this is impossible to fully fix, no room is 100% sealed, but still check for bigger openings that you could maybe seal temporarily.

And hopefully you will be able to afford a small AC unit, maybe a used one in good condition and clean. Look into portable units, i assume they are cheaper but i never owned one so hopefully someone can help you with that.
You will need cooling soon when the summer comes, especially at the end of the flower and drying. And AC units will also help dehumidify some of the air while cooling. Also that dehumidifier surely puts out some heat, at least mine does.

The filter did look a bit dirty but it's only 2 weeks old.
it's only 2 weeks old so I don't think it could be the cooling gas?
My carbon filter sleeve looks a bit dirty maybe I could replace it I do have a spare one :)
All intakes flaps are open :bigjoint:

Increase air flow and air exchange rate bring heat up two or three degrees. And make sure outside room humidity and ambient temps aren’t contributing to your tent humidity room humidity should be desired tent humidity to keep them the same. Expelling hot humid air into room will just keep the high humidity in the tent as it’s not really going anywhere.

I imaging with a dehumidifier running his heat is up plenty, I still think a portable ac blowing out the window will control the environment in the room giving him cooler 72 degree 35% humidity air to draw into the tent, making his tent about 80 degrees f at 50 55 rh

I run forced air type heat that creates really dry air in my room and a portable ac through the door and have like seven fans moving and a dehumidifier to keep my stuff at a desired 81 -83 degrees and between 50 to 62 percent humidity depending on the outside weather. Then I Hoover around 65 when it rains but I don’t see any real problems with it in the may area

Did you just water your plants. How long has it been that high for. I have separate room in a basement and can keep it 20% difference from the adjoining room. Do you have any standing water in your tent. How is your exhaust a dirty carbon filter will retain moisture and not pull properly leaving stagnant air in the tent.

No I haven't watered my plants yet and I am in coco which means I need to feed my plants daily and if I feed until run off that is going to increase the humidity to about 85%. But I need to feed them today

I would try and remove the air from the outer room with fans and ac bringing it to more stable humidity in the high to mid 60’s and bring up the temp In The tent to create a somewhat vacuum effect if you drop your room humidity and create a good exchange rate in the outside room it’ll make the humidity travel from the tent with the heat to the outside room expelling it from there should lower tent humidity. Also have you cleaned your dehumidifier filter if it’s dirty it won’t remove moisture at the rate it’s designed to. Also radiant heat doesn’t always work with bringing down humidity you want to use a air flow type of heater.

Dirty or not remove it, you gotta move air or your gonna loose your crop. Try to send that air out the window or into another room to, not just out of your tent

I think I figured out my problem. Because my plants are in the second week of flowering they are stretching a lot (2inches per day) and the inkbird sensor was slightly leaning on a leaf and giving a false reading. I moved the sensor up by 1 inch and now it's reading 55% humidity again :bigjoint:
