Hey Zeb!
Using a fan or a ventilation system will change the humidity. Also if you cool the air using an AC unit, or compress it using an air compressor then you can remove the water content.

May not be the best solution but if you can get 240V in or outside the greenhouse - take a second-hand dehumidifier, and connect up the plug to a relay board. The picaxe will then be able to turn on and off the dehumidifier through the relay, hopefully changing the humidity.
