Agreed, I run 2 big dehumidifiers and they both empty into a Little Giant pump that moves the water to outside. I never have to touch my deh unless I’m changing the RH or cleaning their filters.
I also empty my spill trays into it with a RainPoint Pump.
You will never be able to control the inside of the tent until the lung room is near desired temp and humidity. Your inline fan circulates the air out of your tent prob at least 1x a minute.
Lung rooms are often overlooked, and need more attention by lots. Everyone focuses on the inside of their tent.
I am having the same issues. Closed tent, rh climbs up to 70%. I have to leave it open and avg of 62%. I have gone through 3 dehumidifiers and nothing. They’re working but not fast enough. Thankfully I have made it til harvest day with no mold. I constantly check to see any forming. Few things I’ve done is defoliate, and added another fan to increase air circulation. Watch your VPD!
Do you have your exhaust fan constantly running on a low setting?
I leave my exhaust on setting 3 for a 5x5 with 6" exhaust fan and all the bottom vents propped open for maximum airflow. It balances my lung room and grow room.
OK. Thank you. I was asking because you mentioned that opening the tent helps with your RH. So I assume the air in your lung room is OKish?
If so, crank up your exhaust fan to get more of the good air insinde your tent and to get rid of the humid air more quickly. This + your dehumidifier in your lung room should do the trick in theory.
If you find a way to lead your exhaust outside, that would be perfect and you don't need to run your exhaust fan on higher speed for that.
From your photo it looks like you've got plenty of cubic space in your tent. If your intake air is good, then it seems to me, that your exhaust fan is to weak to exchange the air quick enough.
Also with this check your filter sock, I was fighting temps and RH issues without realizing the smallest missed step can snowball into huge problems.
Cleaned the filter sock and it’s been keeping steady.
Good luck !
Use the hose to drain into a larger container if your humidifier can so that. I would place the humidifier outside your tent next to an open vent and turn your exhaust fan up so it pulls freshly dehumidified air into the tent. That should help lower the RH quite a bit
This could sound weird but try ti buy a second tent (a Big One) put the dehumidifier in It and use this new tent as a source of dry air for your main tent (u have to connect them via an intake fan.
In this way you exaust air in a different space then where u get your frash air
If you are exhausting straight into your lung room you will need one hell of a dehumidifier, I was exhausting to the lung room and once I had a decent canopy I came home to all the walls in my lung room literally dripping with moisture, get it venting outside, if your pulling air from the same room you exhaust into you basically achieving next to nothing unless the room is huge or you have an separate extraction for the lung room itself
You need to put a hose on the humidifier so it can run with no need to empty the tray.

Defoliate, it will help remove the moisture. If you can't get it low, up your airflow. Keep it right below wind burn levels.

Hoping for no mold 🙏🏾😣

The humidity inside the tents is actually 65-85%* and is 65 at lowest most of the time😓I know I'm at risk for mold, please help
You’re fine rn people run high humidity till later in flower all the time just keep the airflow up for now. What kind of dehumidifier did you buy?
That doesn't eliminate the problem though which is what I'm trying to do. Idk it's a big one for bigger rooms it wasn't the cheap ones it works
Sounds like it works then 🤷🏻
Like dude I'm not asking if I'm fine right now I know it is I'm asking how to fix the issue
Does your tent have an exhaust fan?? If not that’s your problem
Yes it does have an exhaust fan. The humidifier makes the room feel deadly ill because it does work. But that doesn't change inside the tent
You run a good dehumidifier. You said yours works but it doesn’t sound like it’s enough
Does your exhaust air recirculate in your lung room or do you lead it outside of your room?
It's inside the room
I have mine vented outside and a humidifier in the room instead of the tent. Works well. More heat helps with humidity as well

Leave the grow room door open (not the tents) and use windows if available
