I just got a triple lamp Maui and for humidity control I drilled a hole in the back in the acrylic, for a piece of 1/2" PVC pipe to snuggly fit through, and then attached this
fogger to the PVC (the fogger's hose fit perfectly over the tiny piece of PVC pipe). The fogger is controlled by this hygrometer
controller. The controller also controls, via it's thermostat, two reptile heat mats set under the Orchidarium. The controller even allows a user set temperature drop at night via a light sensing diode on the controller's main panel that senses when the light are out (I set mine for a 15F degree temp drop at night).
All of this has allowed my Maui to automatically hold VERY steady to my set parameters for intermediate and warm growers— 78-81F peak during the day, 63F-65F at night and 60%-70% relative humidity.
I find the circulation in my Maui just fine. It draws in plenty of fresh air, and the plants are often slightly moving in the breeze—and these are stiff leaved standard Catts too!
Now I just hope the three CF lamps are enough to get standard Catts to bloom...!
