Hi Soon,
Haha.... If I move in there'll be no more room for your plants...
Yes, I think for any enclosed setup, the main concerns will be heat dissipation (if using natural sunlight as the light source or part of the light source) caused by "green house" effect and air movement. The mister used by swiftlet's operators should be perfect for a cool room and cool house, the unit will produce ample humidity and some air flow when it's activated. It's also durable and practically self sustaining once setup properly.
You may need a controller with sensor to control the humidity and temperature. There's such a device where you set a certain range / limit for temperature / humidity and it'll trigger on/off the power to the device you wanted it to be control. Should come in handy...
