You need to be patient when moving Nepenthes around since they seem to take at least a month or more before they will start responding to the new conditions. My N. rafflesiana (or hybrid?) wasn't doing very well until I moved it. It produced 2 beautiful pitchers about 2 months later and now it has a 3rd! Below is the link to the 2 pitchers together.
I haven't taken the 3 pitchers together yet.
If you move the plant every week or 2 it will be very difficult to know which is the best position for it.
Happy growing, or in the case of my plants, happy swimming! - We've had soooooo much rain recently!
