I meant that I've never run a tank that was an actual terrarium or vivarium - all I've ever had before were aquariums (fully aquatic for fish and/or aquatic newts).
The little tester terrarium is still going!

I haven't seen any growth yet (most of the stuff in it is slow-growing anyway), but nothing has died, so far, and the soil is staying nice and healthy.
I'm really itching to start a full-blown thing with waterfalls and everything - I wanted to run this little tester-terrarium for a while, but then I realized this weekend that I HAVE all the materials I need to set up a more complicated tank, just sitting around in my garage! (Except the lighting I would need).
In order not to drive my husband out of his mind, I am forcing myself to finish the projects I'm already working on before I start a new tank, LOL. I'm one of those people with fifty thousand things going on at once, hehe. At the moment, I'm refinishing my master bathroom cabinets and an antique desk.
