charcoal for humidity?

Has anyone ever used this for humidity control? Humidity is getting close to 65-70 while on 12/12

It won't work for changing humidity levels.

i think putting a basin of water / cup of water in your grow room would add humidity.

don't think charcoal will reduce humidity.....65-70 is high but not that bad

run a fan 27/7 in your flower room. The air movement will drop your humidity.
If that's not enough your going to need to exhaust the air from the flower room, and run your fan in the flower room.
or a De-humidifier if all else fails.

charcoal for odor control.

I have the same 'problem'. Highish humidity but excellent airflow.

Eh let's go with a trial and error method...

50% or higher can and will create mold issues in your room. Bud mold can come on quickly and is not noticeable until its too late. I would not fool around with humidity if you are flowering already. Buy a de-humidifier and run your room at 50% or lower(mine is 30-40% always). You will gain back the cash you put out for the unit in your first crop. The plants will love ya for it!

What's 27/7?

that extra 3 hours a day really must pack the weight on!

I think that should be 24/7 or 24 hours, 7 days a week.
If you have a circular fan in the grow room (not in the box) that should reduce the humidity.

What's your set up?

Cab grow 4 cfl bout a 1.78 liter pot. Have to keep the doors open due to massive heat build up. Just transplanted so plant is pretty well wet from 3 days ago...

It is also slang for "24 hours a day, 7 days a week."

Well I put a cup in there of charcoal in and it dropped it a good 5 percent in the past few hours.

The whole room dropped 5% because of a cup of charcoal? Bull shit, just run fans 24/7 as advised and forget this crazy idea.

No a cabinet... Can't read? Need help? Stop smoking so much bro....
