Thanks Mighty! Honestly, all I did with it before tonight was mist it every once in a while, and air it out occasionally. I anticipate the hydrocotyle might be a bit unruly for the setup long term, but it looks cool and I don't mind having to trim it occasionally. Otherwise, the nana petite and the pillow moss are pretty slow growing, and as long as I don't accidentally let it dry out, it pretty much takes care of itself.
Hydro, I don't think you can keep iguanas and geckos together... Their families have been feuding for generations. Kinda like the Capulets and Montagues. Most of them don't really care any more, but feel trapped by societal pressures to keep up the facade. Or so I've heard...
