i want to built up a highland nepenthes terrarium since I've started cultivating CP's. Now I have the ultimate place (or not?) for this. A vine cellar. There's a constant temperature of 12-15°C in Summer even if outside temperature is 30°C!! In winter the Temperature is about 10-13°C. So I want to built a 114x60x80cm terrarium. I'm going to built a terrarium just out of wood and then I will line this with pond film. For illumination I thought about a 400W metal halide lamp. For extra cooling I'll build a fog machine and for extra heating I'll have a 40W heat cable.
What do you think about this idea?
