Hi!! So I’ve been struggling with humidity in my grow tent. I have 3 fans and an EXHAUST (not intake i originally (stupidly) posted) fan (set to 67%) going AND a small dehumidifier but it will not go below 73%!! Any recommendations or suggestions??

Without knowing more either a bigger dehumidifier or find potential sources of humidity and correcting, like covering the tops of pots or buckets, etc.

I’ve also fucked up many many plants in the short time that I’ve been growing so I’m like hyper focused on trying to make sure everything is right

I am still new to all of this, but it was my understanding that when you’re in flower phase to be below 70%

Meh...you only need to worry when you start to see white patches(powdery mildew) on ur leaves...until then dont go chasing shadows...or 'yak shaving' it's also called.
Yak shaving is programming lingo for the seemingly endless series of small tasks that have to be completed before the next step in a project can move forward

Are you

Do you have an actual exhaust fan pulling air out of the tent through a duct? From my count you've got an intake fan, and 3 circulation fans.

sorry yes in addition to the 3 fans that are going I do have the cloudline infinity exhaust fan-that I have programmed to 67 but it’s not dipping below 70

So you don't have an exhaust fan? If you're only running one fan for ventilation it should be an exhaust fan rather than an intake fan. Suck the moist air out of the tent and that will pull drier external air in.

Fuckkkkk I’m screwing this post ALL up. It’s an exhaust fan not intake. Can I delete this and start over haha??? I know you experienced growers are rolling your eyes. Sorry. The fan is not going outside. It is circulating back into my room that my tent is in. I didn’t care about the smell . I haven’t had any humidity issues in this until it’s started getting colder outside. I turned the vent off in this room for our heat and that doesn’t seem to be helping either.

That's your issue, you need to dump the air outside.

I was worrying about this not long ago, but I was told if you have a inline fan sucking air out the amount needed within minute.... And if you have fans pushing air around. You will not have to worry much about humidity use a vpd chart and that will help you!
