How To Humidify A Grow Room When Exchanging Room Air Frequently?

I have a grow room with exhaust fan and a circulating fan. The humidity in the room is about 25% so I added a room humidifier to try to bring it up to 50-60%. The problem I have is that the humidity is being exhausted out by the exhaust fan. The humidifier I have is 4 times larger than needed for the room already. The fans and humidifiers are running 24 hours per day. How do I get my humidity up and still keep fresh air inside?
 
Ahh yes, this is the same issue I encountered when first growing. I dont have a humidifier on my furnace (I really should get one) so my humidity drops in the 20's in winter. It's also several degrees colder.

Running a humidifier with exhaust is like pissing in the wind... you're wasting your time, unless you humidify the whole room.

I reconfigured my intake to pull from outside my tent and disconnected my carbon scrubber. I have an air cooled hood otherwise I'd shut the exhaust off entirely. So the fan is pulling from and exhausting in the room. I open an upper port and let the air inside the tent humidify by the natural transpiration of the plants and evaporation of the media. This keeps humidity up. This can only be done in veg if you're concerned with odor. But it works well since you want low humidity in flower. So just hook up the intake back to the scrubber and off you go.

Hopefully this makes sense. I apologize for my brevity as I'm about to walk out the door.
 
If you can, plug your fans in a thermostat, so that they kick in only let's say when temps go over 80. When they don't run humidity will go up. Check out Saturn 5 by titan, spendy controller but that's all you'll need. It will run your temps, rh, co2
 
Last week, I spilled about 2/3 quart of water on the floor of my basement. I threw down a old towel and soaked up the water. The humidity in my basement was 46%. I left the soaked towel on the cement floor to see how that would impact the humidity. It went up (about 15 feet away where the humidistat is) to 53% and stayed there overnight and slowly came down as the towel dried over the next 30 or so hours. So I agree that it works.
 
Yes yes yes and yes again!!Haven't done it,seen it in every single room ive been in!!A flat surface with a wet towel,***thonk*** and humidity goes up,want more? Put 2 on different sides/places in the room!!
 
I'll come back at myself for what i said earlier in this thread

My the room the tent is in got quite colder the last two days and the towel/bucket stopped giving out humidity due to lower density limit of the air!Now giving out a max of 2% where it was 12%+...
 
I will give the wet towel a try. Are there any concerns this method might create mold spores though? Maybe hang it on a small clothes line type of thing?

Hey kola, Saturn 5 is the one, basically same as 4 but with more controls and ways of tweaking things the way you want. That thing is the CPU of my grow, no exageration.
 
When it dries replace with clean one...

I recently found out that an extra pot with dirt in it watered down puts off great humidity...
 
I just hung a soaking wet beach towel up in the grow space and it raised the humidity 5%. The towel with one end in a bucket of water to wick up more moisture might be a good idea to try too. Thanks.
 
Wont the wet-untreated medium make bacteria and stuff that i don't have to deal with in pebbles? If not i can do that tonight already,i have 2 11lt pots i can fill with forest-thick mud that hold a shit load of water!!The wet towel thing just takes up space and does weird things to the smell in the air!I also like to witness a spotless space free tent in a 1.5x1.5m one that can be easily clogged with just the basics you need ;/

Another thing i thought about is using the choco haze i got as freebie in soil with a bit of clay pebbles and starting it tomorrow without manifolding it (it will veg along the 2 remaining weeks of the Church maybe 3 and then flip 2gether! Im not sure if i can use my RunToWaste nutes in pebbles/soil if i actually run it all to waste with a 10% runoff minimum...
 
Oh no thats not what i said lol!!If i can use my nutes that are only for RunToWaste systems in a soil-pebbles mix if i ensure there is enough runoff!
