Wow so many questions. To tell you the truth I was drooling over all the cp plants and blinded to other things.
Robert,
I think it is a combinations of misting, drip piping (as used in the growing of strawberries) and running water. In the above photo you will see plants sit on troughs. Water are passed through these troughs. The plants are grown in pure sphagnum moss. So water are then absorbed by the moss. Since this is a highland area, the heavily precipitated air also helps to keep the top layer of moss moist.
Lim,
The above photo also showed the floor is covered with some kind of plastic.
Bonsay,
This time of the year is the rainy season, so the temperature is cooler. I estimate the night temp to be 20°C. But I think the wet humid air is more important than low temperature.
Varhoon,
I have no problem buying three large sarracenia hybrids and a large veitchii (hose mountain). But have to beg before they agreed to sell me N. rhombicaulis (NE-69) and N. diatas (NE-92). The two plants are about 3 inch across.
If the trip to CH with David and Dr Charles Clark materialise, I will try to go YG again to get answers for all these questions.
