So I'm just getting into Nepenthes and other carnivorous plants in my vivariums. My first attempts were growing N.ampullaria from seeds, and growing sundews on a moss drip wall. So far I've had success. Now I have a N.campanulata on order. I'm debating putting it in a terrarium with frogs where it will be placed on a piece of driftwood with some moss. I know they grow slow and stay small.
I've read they grow as a lithophyte as well, so can I get away with a small amount of sphagnum moss around its roots? Will that work or will I need the typical Nepenthes substrate mix I keep finding on websites?
Thanks for the help.
