I don't know what plants to recommend you grow in your office, Rob...My
terrarium has only one little 10 or 15 w bulb, and I grow all different
species in it, but (importantly), the terrarium is in front of a window,
so it gets a lot of natural light. BTW, if anyone considers putting a
terrarium in front of a window, remember to "crack" the lid (i.e. leave
open a cm), or the greenhouse effect will fry your plants.
garding bugs, chances are, the gnats' eggs are in your plants' media, so
they will probably crop up in your new terrarium, too. I remember an old CPN
article talked about buying and breeding fruit flies as CP fodder, but that
seems like too much work to me. But
maybe worth considering. Plus, you
can do genetic research as you raise food for your plants!
