I have an N. ventricosa and N. sanguinea I'd like to repot. They are currently in the soil mix I purchased them in, which I believe is peat/perlite/vermiculite, and would like to switch to pure LFS for simplicity. Would switching media have any adverse effects on the plant? I've heard that the roots are very delicate and that any disturbance could put the plants into distress, so any tips on minimizing the damage? I've repotted VFTs and Sarracenia before without any problems, but Nepenthes worry me a bit.
