Condensation on tent walls. Cant identify problem

[Siz]

That humidity is wild, I don't know. We are missing something here....

I have never ran into the R.H getting any higher than 65% so it was easily dealt with, by using a little 40 pint dehumidifier.

I am running high rh for veg and im flipping to flower tonight. Ill drop the dehu one more stage to see if it makes a difference on the condensation.


Would that buildup on the wall be an issue in flower?

Im going to try upping the intake and extraction. I had them on a lower setting because the dehu wouldnt kick on

It will make your bud mold, it's because your humidity is so high that you have wet walls. I max at 65 in veg, 70s is for seedlings. You are playing with fire having the humidity so high

Agree. Growth is insane but I am playing with fire since my environment isnt 100%. Im sitting next to the tent playing with all settings to see what will work. If I cant get it to work I will definitely drop the rh and possibly even move the dehu out of the tent.

I was trying to keep the tent warmer than the room by keeping the intake and extraction on the lowest setting so now Ive upped them to see a closer temp and rh from outside to inside. Hoping this can help

If you set your exhaust at a slightly faster speed than your intake, you probably wont need a dehumidifier. A bit of negative pressure is all I have ever done, and it sits at 53% R.H during the entire flowering cycle. No mould issues!

You can have explosive growth at lower humidity it's a genetic thing mostly. Vpd is crap in my book, thats just me though. It's fun to experiment sometimes just be careful

Ive tried but I think my tent is stuffed to the max lol hum stays up there.


I just took out the dehu still trying to find the sweet spot. Less swings but the dehu is constantly running

Negative pressure is what I use as well, I've never had an issue with mold or anything.

Just remember like 95% of the water your plamlnts uptake they put back into the air.

Yeah its just not efficient because all the humidity is in the tent. When dehu was inside it would cycle on and off. Outside the tent I have 2 dehu’s running to bring it down.

-___-

My intake and exhaust are overpowered so I tried all combinations of negative pressure. From high exhaust low intake to same speed to low exhaust high intake.

Ahhhhh! Im going crazy hahahaha

Says dew point is 74.3. Lower your humidity or raise your temp it should go away.

Swings flattened but had to raise my room temp by 6 deg and im still not as high as i would like to be.

Temp inside and outside tent are same. I have 2 dehus running continuously 80 pint and 95 pint.

When i had the dehu in the tent it was running off only the 80 pint and it would cycle. Its very inefficient running it this way but the temps are super steady for the plants.
