So I have a 65g hex aquarium & stand that I want to set up as a terrarium. I've never made one before, and I figure that I've got two options. 1) Transplant all my various potted cacti into the terrarium and use it is a dry terrarium. 2) Get new plants that prefer a humid environment, and take advantage of the closed lid, etc, and enjoy something new! Probably I'll do #2 and so I thought I'd pick your brains to see if any geophytes make good terrarium specimens. I'd love to try irises, but I suspect they need temperature fluctuations throughout the year to grow & bloom properly??? I'm guessing. Another option would be to experiment with native plants. Like maybe try the native Opuntia humifusa (which I grow outdoors just fine) or Manfreda virginica, or something. But somehow that doesn't appeal to me as much as growing something tropical. I hope this stirs up some good conversation! Dennis in Cincinnati, Ohio, USA
