After seeing those nifty Utriculariums that Swords built, I had to try my hand at it!
Its just cork-bark (formally used to grow dendrobiums) cut and sanded to size to fit the large "Cube of Death." I have LFS in rain water at the bottom, into which I planted a plug of U. sandersonii 'Blue Form.' I hope that it fills the space and even climbs the cork-bark one day. (My apologies for the blurry pictures)
On the cork-bark itself, and inspired by reports of Mexican Pinguiculae growing on the trunks of trees, I put a few pullings of P. moranensis cv. unkown into some cracks and crevices. Im hoping at least a few will really root in (as best as a ping can!) and that there is enough moisture wicked up by the bark.
I have it sitting in an east-facing window, getting direct sun for a few hours in the AM then brightish light the rest of the day. We'll see. Thanks for looking!
