This Wabi Kusa / Terrarium was inspired by James Wong which I set up yesterday. The container is about 10cm in diameter and has a cork lid to keep the humidity up. I'm using Bucephalandra 'Mini Needle Leaf' and 'Mini Catherinae', Java Moss and a piece of Icelandic Lava Rock I collected on a trip last year, so it's become quite a nice souvenir. The moss was grown in the submerged form, but I expect it to flatten out and grow upwards eventually. The Bucephalandras aren't glued or buried and they can root into the Aquasoil or on the rock if they want to. It's really nice and low maintenance, but as you can see the glass is a pain to keep clean.
