Don't know about the parrafin... They don't "need" high humidity
as much as Nepenthes do but it wouldn't hurt. I've been growing
mine (two hybrids so I don't know how much this will help) in
normal humidity = whatever it is in my house. They seen to be
less brittle and much less prone to fungus this way. I have them
in tall pots with a mix which is basically Nepenthes mix:perlite
in 1:1. My Nepenthes mix is (2/3 peatmoss, 1/3 perlite or styro-
foam, 1/3 diatoms):(orchid mix or pine bark) in 1:1. The pots are
sitting in water. The "trick" to them is the roots must be wet
but they must also have good air flow to them also. I wonder if
sand:perlite:peat in 2:2:1 would also be a good mix?

P.S. I doubt you could give these plants too much light, pour on
the sun.
