I am setting up a lowland nepenthes terrerium and I am wondering if it is possible to grow a sphagnum "carpet" in lowland conditions. The plants will be in potts, but the pots will be sitting on those expanded clay things (forgot the name). Since they are used in hydroponics and hold small amounts of water, I figure that they would be a good medium for sphagnum to grow over. Is there any one type of sphagnum that grows better in warm conditions. I have a small patch of sphagnum outside that survived a 105f heat wave for 2 weeks, but I heard that standard sphagnum used in outdoor bog gardens needs a cool dormancy. I have heard that in SE Asia, sphagnum begins to appear at about 1000m elevation and is largely absent in the lowlands.
