Plant people are crazy!!!!  And also, I'm totally jealous of that orchid
chamber.  And also, that Hippy is unbelievable!!

Thanks for the great pics.  I just planted my 11 Hippys in regular boring
dumb pots.  Actually that's not true, several of them are potted
semi-hydroponically this year, like I my orchids.  I bet they love it!
