I had "quit" Nepenthes and all growing of plants in late 2006 early 2007 but I have been slowly sucked back in starting with succulents in 2009 and vivariums in 2010 and now (inevitably) here is my new Highland Nepenthes chamber. It's based on the same principle as my old one but using a new controller the Zoomed Hygrotherm.
Before triggering the controller:
The fog gets so dense at times you can't see anything but I've got it set to stop before anything gets wet so it stays nice and high but not too high. I've still gotta fidget with the fan and temp settings, it's too cool! LOL
The Hygrotherm controller can be set for daytime temps and night time temps down to 50*F. Humidity can be set between 15 and 95% RH. The photosensor on the controller display senses the terrarium lights going out, room lights, TV, PC, etc will not prevent it from going into nighttime mode so that's nice for night owls like me!
This piggy back cord for the controller accepts 2 and 3 prong heating/cooling and humidifying appliances and the LED lights up to show which appliance (or both) are running.
And here is the meat and potatoes of the whole thing: PC fan in the window, 4" diameter duct tube, ultrasonic humidifier plugged with a piece of 2" diameter sump pump hose that intersects the duct to humidify the incoming air when the humidity drops.
Just one day after moving my stuff in here I THINK I may actually be witnessing a Nepenthes inermis germinating, can anyone confirm from this crummy pic? It's definitely not moss, I've watched that germinate in all my other Nepenthes seed pots... LOL
