This may be a longshot, but I have a large N spectabilis "giant" x ventricosa that is near flowering size and looks to be close to the vining stage, and I am interested in a N. hamata. I have had the plant for a little over a year starting off from a small cutting. It consistently produces pitchers even in low humidity conditions. It has produced two basal offshoots so far, and currently has one pitcher that is ~7 inches in length. Below are a few pictures of current and past pitchers, and the entire plant. Each leaf is ~8 inches long currently.

Shoot me a PM if you are interested. Thanks
