Ideally it'd be moss and a few smaller classic-looking ferns.
What type of moss (I like the color/texture of rock cap, if it would grow on soil too in the following conditions?) and fern (Athyrium otophorum maybe?) would be good for something like that? Something that is okay in fluorescent light and a light amount of natural light from a window. Room temperature(68 - 72 deg'ish), any type of watering schedule is fine.
Also I've been reading a bit about planting and I've been seeing that stones or rocks underneath the soil (as a sort of substrate) isn't necessary, is this also true for my application?
Ill also attach a type of container im considering. (-the wire frame, any suggestions on lid on vs off?)
Any other suggestions, tips, comments? ... Preferably constructive.
