It comprises a big terrarium with sliding doors (130 cm long, 110 cm high and 60 cm large):
The terrarium is lit by a 250 W Metal Halid lamp. It is of course possible to use other light source such as HPS lamp, fluocompact tubes , T5/T8 tubes or envirolites.
The spectrum is not perfect (there's not enough red) but it is more than enough for Nepenthes culture. I grow tropical pitcher plants with this kind of light for almost four years now.
There is 10 cm of water at the bottom of the tank. I placed an aquarium heater which heats the water at 26 °C. I thus obtain a very good level of humidity (70 to 80 % at day and 100% at night.
The terrarium is placed in my living-room where the minimum temperatures is 15 °C at night. Thanks to the aquarium heater, the temperatures never drop below 20°C.
I will soon set some fans for air circulation. The lowland plants have been grown for a few years without air circulation but I'm convinced that air movement will be beneficial (I already tried that for a few months in the past).

Francois, Your lowland tank must be very humid in there. I have never known Hoya lacunosa to produce aerial roots before. Your N. bicalcarata is just the best in small size and color. Well done! My bicals average about four feet across and about five feet high, and these are the small plants!
