I was finally able to snap a couple of shots of two of my better highlanders. It took a while to get the highland tank set up in the basement and after about a year and a half of nothing from the N diatas, it obviously likes the current home:
Last summer I did get a couple of pitchers on the N spectabilis, but they weren't at the same time. Now there are 2 open, 2 forming and a basal with 3 or 4 pitchers on it.
I am hoping that this means that I can finally start trying some of the more finicky highlanders. The diatas was a big confidence boost that I was heading in the right direction.
I'm not sure of the conditions in the tank. Humid-very humid.
