Thanks! I've found other sites for folks doing aqua-bonsai... I'm not taking it too seriously, at this point. It's easier for me than dirt, because I can tell at a glance if my poor plant needs water... oh dear, it does... but the fine roots didn't dry out thanks to capillary force.

Weird thing about bonsai, the goal isn't to maximize... more like, I wanna just fail at killing the thing.
