question abou humidifyer

At what height should i place a humidifyer? Up or down. Thanks

i would say up, however its personal choice hope this helps

Thanks for the replay. I am wondering where is the humidity going upway or downway eg. is it heavier than the air

hot air forces the humidity up plus if you are using an extraction fan
this will cause the water molecules to rise too,hot air rises cool air falls
basically,i am using a de humidifier at the moment and it's near the roof of my growroom
this is the only place it seem's to be effective,when i have to use my humidifier i place it on
the floor in the centre of my growroom,i could be wrong,but this is the way it works best for me,hope this is of some help
to you!!

what is your humidity level. you may not need a humidifier.

if you create to much humidity you will create havoc. I never used a humidifier ever cause i have 45 percent humidity constantly

I forgot to say that i only use a humidifier in my veg room,i like to keep it at 60 - 70% in there,
and as vertise said i like to keep mine as close to 40% in flower if i can and even lower getting near harvest,
once you get a mould attack once,you will never want to repeat the mistake of having the hum too high in
your flowering garden!!!
