There are some species of succulents that require no water, no fertilizer or any fertile ground as such, no wind, no nothing really except bright light... survive temp ranges from -10 to +35 C and grow about a cm in a decade.
Actually you can only kill them by caring for them and plunging some water on their head.
If all else fails... ;D
What normal soft leaved plants need most is just 2 basics...
1- Bright light giving a spectrum for photosyntesis
2- Fertilizer
Edit: 3- And water of course (but that should be obvious)
You can drop all the perfect ground and fertilizer in a vivarium, but if the plant can't properly photosynthesize, it is useless and it will eventually die.
A normal 60W light bulb with a color temp of around 6-6.5K is about as bright as a shadow is on a summer day. Once you know that you realize just how bright a light should be for plants that require full or partial sunshine. Of course there are specialized grow light giving off a huge purple hue which to the human eye seems to be far less bright, but heck, you do not want that in your vivarium
If you google images of "photosynthesis color response" you'll see the color spectrum plants desire. You see high peaks in blues and reds. Now if you want to make the light pleasurable to look at (ie- resembling sunshine) you need it either to be white or slightly warmer to yellow. To attain those high peaks in blues and reds with the appropriate other colors, you'll get intensely bright white light as a result. Hence LED lighting is so popular because it can in fact create very intense light over shorter distances at a reasonable price, so you can actually grow plants in a room which is in fact dark without the use of the old (and big, expensive, energy sucking) grow lamps.
PS. I'm dutch, I now keep my fingers crossed that the police isn't going to knock on my door asking questions about growing plants indoors in a dark room.
