Here is one for the field observers/growers(Andreas, Rob-hope you are reading this one)
I was wondering how many people out there adapt their compost formula, based on the habitat description of a particular species of Nepenthes.
For example, if a certain species grows in mossy forest, as an epiphyte, does it actually grow in the moss on the trees? Therefore, wouldn't sphagnum moss with some bark be a good choice? I think most people who try to cater to epiphytes use more of a bark medium(or other chunky materials) and less sphagnum or peat.
I think we touched a little on laterite, which seems a good component for somwone trying to copy ultanmafic or ultrabasic soils.
I guess another example would be trying to grow N. lavicola with lava rock(scoria) in the compost or at the bottom of the pot.
I get curious when I read the specific habitats of these plants, even though most grow them in their standard composts.
