I used a peaty mix to start but when i actually repot i will move to orchid bark/perlite mix. I am not crazy about repotting and neither are the nepenthes. I generally don't give them much daily water(10cc or so)....basically what they need to keep the soil damp; however with the slow moving water I am assuming at some point I am going to have to add some fast moving fresh water to flush out the slow moving stagnant water trapped in the soil itself to keep the nepenthes happy.....or I could be over thinking it.
If so what would a good recommendation be? flush every 3 months maybe?
