Controlling humidity

Aside from a dehumidifier, how can you control humidity in a microgrow?

Are there simple/inexpensive ways to higher/lower it?

Does the frequency of watering have anything to do with this?

Lower- more air exaust

Higher- water jug in grow room.

An air conditioner will not only cool the room but will dry the room at the same time.
