how do I raise humidity?

I live in so cal and the humidity has been very low lately, around 25% what is the easiest way or best way for me to raise it? will just a few buckets of water do it? I think my fan that cools the lights is sucking out the humidity, could this also be possible?

ye try forst to put few buckets with water there.

the move venting the less humidity.
you could do either of the following:
decrease venting.
add buckets of water.
use a humidity dome over the plants. any clear container would work. to control humidity levels add holes that will allow humidity escape.

are you in the veg. or flowering stage? in flowering its ain't that bad.

Thanks I am trying that now its just very dry in so cal

I am in the first day of flowering after a 6 week veg they are about 24" tall here is a pic I am so proud. this is just from a minute ago, arnt they lovely?thanks for your help

they look fantastisch.

25% humidity is a bit dry, just lower your ventilation a bit and get humidity to 35%. they should be fine with 35%.

Foliar feeding will also raise humidity. How much depends on how heavily you feed.

You can get a decent cool air humidifier at walmart for $30. Works well but needs refilled often.

Thanks I and first going to get a controller for the hydro store and turn down the ventilation. If that don't work I will check out walmart. Peace & love
