Well the LED experiment has sort of fizzled. My Christmas cactus rotted (I mistakenly put water inside the soil of a moisture-wicking african violet pot, creating cactus soup), and the carnivorous plant seeds never did germinate. (Of course the ones in regular light didn't either, but I'm hanging onto hope with them). In here I was just over it.
Now the lonely pothos has the wardian case all to himself.
Still growing nicely, though not exactly huge.
