Well, I don't really have the option of setting up a terrarium where I live, so I'm going to try growing some Neps in my windowsill. House is air-conditioned, so humidity is almost nil. Window gets a bunch of sun in the evening. I've been reading nepsaroundthehouse for tips and recommended plants.
N. ventricosa red x talengensis
If you have any experience with windowsill growing, let me know! I searched for my copy of The Savage Garden, but I failed to find it (lost in storage, probably eaten by rats/birds). I know that Peter discusses it and grows several difficult plants in his windowsill.
Edit: Is the general consensus that manually misting would not help much?
