@Avery I believe they are seed grown; I joined willy in importing them in from labflytrap. I‘ve tried many nepenthes seeds in the past without any success; hoping one day I’ll be lucky. My traditionally-grown nepenthes are slow; these guys have doubled in size while my seedlings got maybe a a few new leaves at best!
I haven’t personally hardened any nepenthes out of TC but from what @Will20013 told me, his nepenthes were incredibly vigorous out of TC from the get go.
This culture was very weird. Initially I made it at home, with a DIY formula I created and the plant was one big callus culture. Overtime, the plant started to grow some normal structures so I decided to bring it into the lab with some proper lighting..... Since then it has exploded in growth.
