How old is your lowii and did you grow it from seed?
Great looking plants! How do you cool your terrarium and at what temp range? How's the eddie doing?
I see that a number of people have success with this species. I acquired 2 clones last year & both are quite reluctant to 'thrive'. Both are growing & increasing leaf size (especially during the cool winter weather) but neither has inflated a pitcher for months. I have a small N. argentii that is even more stubborn --- meanwhile another clone is growing great. Go figure!my N glabrata has about ten growth points
