High Humidity

Hi guys, I have got high humidity 2 weeks into flower and I can't lower my humidity it's sitting at nearly 75% and I'm worried I might get powdery mildew or bud rot or both.IMG_0274.pngI'm using a 25 liter Dehumidifier and it's not bringing the RH down. But it is removing over 10 liters per day. What can I do? Do I need another 25 liter dehumidifier? I'm only running a small 4x4 tent. It was working for 2 weeks and the humidity was sitting around 55% - 60% but now it's shot right up to nearly 75% RH. I have checked to see if there is a problem with the dehumidifier but there isn't any problems. It's still pulling water from the air and storing it inside the dehumidifier.

Easiest option would be to increase temps a little. But as far as humidity it might help to try and place the dehuey outside the tent by the intakes and have it only pull from where the dehuey is. The cycling of a dehuey can be a real PITA.

I already have it outside the tent by the intakes dude. I'm literally struggling I thought a 25 liter Dehumidifier would be enough for a 4x4 tent. The air feels really muggy today. Do you think the humidity outside could be why it's so humid in here?

Yes for sure outside ambient humidity affects inside. You should watch the 25liter and see if it is cycling off...if so you may want a larger one or second one. It adds heat though the more you have.

Ac in surrounding room and dump tent air into ac, ac exchanges outside air as well...?

I just have a 4x4 tent exhausting outside of the room and the door is pinching the ducting so it remains closed as much as possible. It's really hot and humid right now.

It's not cycling off. It's just not reaching the humidity I tell it to go to. If I set it at 35% RH on the lowest setting the best it reaches is 45% outside of the tent. But it's still 75% RH inside the tent. And for the past week or two it's been sitting at 55% Humidity and now it's raised to 75% humidity and my bathroom is right next to my grow tent so I can't have a bath due to the fact it would increase the humidity even more. I am fucked.

Its been 95-100% humidity here lately so i feel your pain. We got 1000mm rain in two days. Even with the dehumidifier running it barely gets under 85-90%. Im in full flower too so its been a huge hindrance. The plant is just not drinking or taking in nutrients at this stage. Took a while to hit the plant hard, but the difference in water retention in the medium is insane. Especially considering it was already hungry a week or so ago. Its now eating itself to stay alive as it cant breathe.

Winter is supposed to be cool and dry here, but its been 80f and 90% humidity constantly. My blinds are covered in beads of water every morning with the windows closed and dehumidifier running. I'm ready to give up too lol. I'm beginning week 6 of flower so it's critical AF.

It hadn't rained at all the other night for a whole day and all the trees and power lines were dripping water still. i came out thinking it had rained and was greeted with stars. Drove home that night at sea level and there was ground level cloud everywhere.

Never seen weather like this going on winter in two weeks. last year it was 50-72f and 40% humidity at this time. Would go a week or two without seeing a decent cloud. The joys of La nina events.
