humidity 95% at night. bad

[hulio]

i got a humidity problem. up to 95%. got a 300mm inline fan/filter sucking air inside grow room and another fn bring fresh air inn. during lights on its fine but when lights off at night humidity goes up. to cold with fan on.7 or 8 degrees. dont know yanky term. anyone know a way o fix this?

make one of the fans suck bad air out. you have to get the humidity down. you need an exhaust fan.

yeah ill move the fan and filter outside growroom. the only reason i leave it inn is cause hydro shop man says can leave inside or out. thanks i ll see how it goes

you can leave it inside, just make sure it is sucking from inside the room and blowing outside.

yeah done that i reckon that make big difference. in bottom corner is 150mm inline fan and the big 300mm one outside sucking air from inside opposite side up high. it lifts the plastic up off the floor.

home depot, rona.. those must be some shitty hydro shops if they dont have dehums

i recommend getting as much air OUT as you can.

and make sure the air you bring IN isnt humid itself.


and hey, look at it this way. it could be worse, that could be the humidity with the lights ON, which could lead to wayy higher chances of mold and fungus.

yeah australian hydro shops. i probably find one if i had a look around. So if only 12 hours of light are humid is this enough to get bud rot? average of 80% humidity with lights off and 55 to 65 withlights on.

I dunno where bouts you are in aus, but where i'm at its fooking cold! And it's dry cold air, not much humidity.. don't tell me you in the NT or something lol

 

[Tree??]

I am having same problem...but my room is a basement with a sump pump therefore always some setting water in it. I covered it up and noticed a small difference. the more moving air you can generate in there the better i would say. and the dehum...yeah i am looking for one too...they are kinda high

 

[hulio]

adelaide. yeah ill just have to run both fans flat out 24 7 that should keep it down. but gets cold at night with fans running. doest matter. ive found some small amounts of water in old upside down pots. fixed that and ill only water small amount each day or two

you want lower humidity and temperature at night day hotter and more humid just like the outdoors themselves.
