Ok, I am going to buy a N. judith finn pretty soon and I want to know how do you know these things. My very first one was about...1 inch diameter, to be honest i am guessing, but it had really small pitchers and it grew really slow...horribly slow. I tried putting ice at nighttime to stiumlate highland conditions and that didn't help it and lowland conditions didn't help either. I grow all my plants outside, if that helps.
